How To Use This Soil Survey

This document supplements the Soil Survey of Tulsa County, Oklahoma, published in

1977 (USDA, 1977). Advancements in technology and more intensive and varied land

uses require updated soils information. To prepare for this publication, the correlation for

the Tulsa County soil survey was amended in January 1997 and September 2000.

This publication includes the recorrelated map unit legend, information on the use and

management of the soils, major soil properties, and the detailed soil maps.

The map unit symbols have not changed. The map unit name and series name may

be different from the first publication, but the map unit symbols and the soil map

delineations have not changed.

The detailed soil map unit descriptions are archived in the original Soil Survey of Tulsa

County, Oklahoma. These descriptions can be useful in planning and management of

small areas, and are available in many libraries or from the Natural Resources

Conservation Service and the Tulsa County Conservation District office in Tulsa,

Oklahoma.

To find information about your area of interest, locate that area on the Index to Map

Sheets, which precedes the soil maps. Note the number of the map sheet, and turn to

that sheet.

Locate your area of interest on the map sheet. Note the map unit symbols that are in

the area. The Summary of Tables shows which table has data on a specific land use

for each detailed soil map unit. See Contents for sections of this publication that may

address your specific needs.

This soil survey is a publication of the National Cooperative Soil Survey, a joint effort of

the United States Department of Agriculture and other Federal agencies, State agencies

including the Agricultural Experiment Stations, and local agencies. The Natural

Resources Conservation Service (formerly the Soil Conservation Service) has leadership

for the Federal part of the National Cooperative Soil Survey.

Major fieldwork for this soil survey was completed in 1968-74. Soil names and

descriptions were approved in 2000. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 2000. This survey was made

cooperatively by the Natural Resources Conservation Service, the Oklahoma Agricultural

Experiment Station, and the Oklahoma Conservation Commission. It is part of the

technical assistance furnished to the Tulsa County Conservation District.

Soil maps in this survey may be copied without permission. Enlargement of these

maps, however, could cause misunderstanding of the detail of mapping. If enlarged,

maps do not show the small areas of contrasting soils that could have been shown at a

larger scale.

The program and activities conducted under the memorandum of understanding for

this survey are in compliance with the nondiscrimination provisions contained in the

Titles VI and VII of the Civil Rights Act of 1964, as amended, and other nondiscrimination

statutes, namely, Section 504 of the Rehabilitation Act of 1973, Title IX of the Education

Amendments of 1972, and the Age Discrimination Act of 1975. The program and

activities also are in accordance with regulations of the Secretary of Agriculture

(7 CFR-15, Subparts A and B), which provide that no person in the United States shall

on the grounds of race, color, national origin, age, sex, religion, marital status, or

handicap be excluded from participation in, be denied the benefits of, or be otherwise

subjected to discrimination under any program or activity receiving Federal financial

assistance from the Department of Agriculture or any agency thereof.

Foreword

The Soil Survey of Tulsa County contains much information useful in any landplanning program. Of prime importance are the predictions of soil behavior for selected

land uses. Also highlighted are limitations or hazards to land uses that are inherent in

the soil, improvements needed to overcome these limitations, and the impact that

selected land uses will have on the environment.

This soil survey has been prepared for many different users. Farmers, ranchers,

foresters, and agronomists can use it to determine the potential of the soil and the

management practices required for food and fiber production. Planners, community

officials, engineers, developers, builders, and home buyers can use it to plan land use,

select sites for construction, develop soil resources, or identify special practices that

may be needed to insure proper performance. Conservationists, teachers, students, and

specialists in recreation, wildlife management, waste disposal, and pollution control can

use the soil survey to help them understand, protect, and enhance the environment.

Many people assume that soils are all more or less alike. They are unaware that great

differences in soil properties can occur even within short distances. Soils may be

seasonally wet or subject to flooding. They may be shallow to bedrock. They may be too

unstable to be used as a foundation for buildings or roads. Very clayey or wet soils are

poorly suited to septic tank absorption fields. A high water table makes a soil poorly

suited to basements or underground installations.

These and many other soil properties that affect land use are described in this soil

survey. The location of each kind of soil is shown on detailed soil maps. Each soil in the

survey area is described, and much information is given about each soil for specific

uses. Additional information or assistance in using this publication can be obtained from

the local office of the Natural Resources Conservation Service or the Cooperative

Extension Service.

We believe that this soil survey supplement can help bring us a better environment

and a better life. Its widespread use can greatly assist us in the conservation,

development, and productive use of our soil, water, and other resources.

Soil Survey Supplement of

Tulsa County, Oklahoma

By Everett L. Cole, Donald G. Bartolina, and Bill G. Swafford, Natural Resources

Conservation Service

United States Department of Agriculture, Natural Resources Conservation Service,

in cooperation with

the Oklahoma Agricultural Experiment Station

Tulsa County is in the northeastern part of

Oklahoma (fig. 1). The county is bounded on the west

by Osage and Creek Counties; on the north by

Pawnee, Osage, and Washington Counties; on the

east by Rogers and Wagoner Counties; and on the

south by Wagoner and Okmulgee Counties. Tulsa, the

county seat, is in the central part of the county. The

county has an area of 375,674 acres, or 587 square

miles.

How This Survey Was Made

Soil scientists made this survey to learn what kinds

of soil are in the survey area, where they are, and how

they can be used. The soil scientists went into the area

knowing they likely would locate many soils they

already knew something about and perhaps identify

some they had never seen before. They observed the

steepness, length, and shape of slopes; the size of

streams and the general pattern of drainage; the kinds

of native plants or crops; the kinds of rock; and many

facts about the soils. They dug many holes to expose

soil profiles. A profile is the sequence of natural layers,

or horizons, in a soil; it extends from the surface down

into the parent material, which has been changed very

little by leaching or by the action of plant roots.

The soil scientists recorded the characteristics of

the profiles they studied, and they compared those

profiles with others in counties nearby and in places

more distant. Thus, through correlation, they classified

and named the soils according to nationwide, uniform

procedures.

A guide for classifying and naming the soils was

prepared, and the soil scientists drew the boundaries of

the individual soils on aerial photographs. These

photographs show trees, buildings, fields, roads, and

other details that help in drawing boundaries. The

detailed soil maps at the back of this publication were

prepared from aerial photographs.

The areas shown on a soil map are called soil

map units. Some map units are made up of one

kind of soil, others are made up of two or more

kinds of soil, and a few have little or no soil material

at all.

While a soil survey is in progress, samples of soils

are taken as needed for laboratory measurements and

for engineering tests. The soils are field tested, and

their interpretations are modified as necessary during

the course of the survey. New interpretations are added

to meet local needs, mainly through field observations

of different kinds of soil in different uses under different

levels of management. Also, data are assembled from

other sources, such as test results, records, field

experience, and information available from state and

local specialists. For example, data on crop yields

under defined practices are assembled from farm

records and from field or plot experiments on the same

kinds of soil.

22 Soil Survey Supplement of

Only part of a soil survey is complete when the soils

have been named, described, interpreted, and

delineated on aerial photographs and when the

laboratory data and other data have been assembled.

Organizing this mass of detailed information is

necessary to make it useful to different groups of

users, among them farmers, managers of rangeland

and woodland, engineers, planners, developers and

builders, home buyers, and those seeking recreation.

Use and Management of the Soil

The soil survey is a detailed inventory and evaluation

of the most basic resource of the survey area—the soil.

It is useful in adjusting land use, including urbanization,

to the limitations and potentials of natural resources

and the environment. Also, it can help avoid soil-related

failures in uses of the land.

While a soil survey is in progress, soil scientists,

conservationists, engineers, and others keep extensive

notes about the nature of the soils and about unique

aspects of behavior of the soils. These notes include

data on erosion, drought damage to specific crops,

yield estimates, flooding, the functioning of septic

systems, and other factors affecting the productivity,

potential, and limitations of the soils under various uses

and management. In this way, field experience and

measured data on soil properties and performance are

used as a basis for predicting soil behavior.

Information in this survey is useful in planning use

and management of soils for crops and pasture,

rangeland, and woodland, and as sites for buildings,

highways and other transportation systems, sanitary

facilities, parks and other recreation facilities, and

wildlife habitat. From the data presented, the potential

of each soil for specified land uses can be determined,

soil limitations to these land uses can be identified,

and costly failures in houses and other structures,

caused by unfavorable soil properties, can be avoided.

A site where soil properties are favorable can be

selected, or practices that will overcome the soil

limitations can be planned.

Planners and others using the soil survey can

evaluate the impact of specific land uses on the overall

productivity of the survey area or other broad planning

area and on the environment. Productivity and the

environment are closely related to the nature of the soil.

Plans should maintain or create a land-use pattern in

harmony with the natural soil.

Contractors can find information that is useful in

locating sources of sand and gravel, roadfill, and

topsoil. Other information indicates the presence of

bedrock, wetness, or very firm soil horizons that cause

difficulty in excavation.

Health officials, highway officials, engineers, and

many other specialists also can find useful information

in this soil survey. The safe disposal of wastes, for

example, is closely related to properties of the soil.

Pavements, sidewalks, camp sites, playgrounds,

lawns, and trees and shrubs are influenced by the

nature of the soil.

General Nature of the County

Additional information about the soil survey area is

given in this section. It will be most useful to persons not

familiar with Tulsa County. This section describes the

climate, settlement and development, relief and drainage,

natural resources, and transportation and industry.

Climate

The consistent pattern of climate in Tulsa County is

one of cold winters and long, hot summers. Heavy rains

occur mainly in spring and early in summer, when

moist air from the Gulf of Mexico interacts with drier

continental air. The annual rainfall is normally adequate

for wheat, soybeans, and all other grain crops.

The table “Temperature and Precipitation” gives data

on temperature and precipitation for the survey area as

recorded at Tulsa for the period 1951 to 1974. The table

“Freeze Dates in Spring and Fall” shows probable dates

of the first freeze in fall and the last freeze in spring.

The table “Growing Season” provides data on length of

the growing season.

In winter, the average temperature is 39 degrees F

and the average daily minimum is 28 degrees. The

lowest temperature on record, which occurred at Tulsa

on December 23, 1963, was -5 degrees. In summer,

the average temperature is 81 degrees, and the average

daily maximum is 91 degrees. The highest temperature

recorded on July 14, 1954, was 112 degrees.

Growing degree days are shown in the table

“Temperature and Precipitation.” They are equivalent to

“heat units.” Beginning in spring, growing degree days

accumulate by the amount that the average temperature

each day exceeds a base temperature (50 degrees F).

The normal monthly accumulation is used to schedule

single or successive plantings of a crop between the last

freeze in spring and the first freeze in fall.

Of the total annual precipitation, 25 inches, or 64

percent, usually falls in April through September, which

includes the growing season for most crops. The April

through September rainfall is less than 18 inches in two

years out of 10. The heaviest 1-day rainfall during the

period of record was 7.54 inches at Pawhuska on

July 27, 1963. Thunderstorms number about 55 each

year; 22 occur in summer.

maximum and minimum daily temperatures, dividing the sum by 2, and subtracting the temperature below which

growth is minimal for the principal crops in the area (50 degrees F).

Tulsa County, Oklahoma 25

Average seasonal snowfall is 10 inches. The

greatest snow depth at any one time during the period

of record was 10 inches. On the average, 3 days per

year have at least 1 inch of snow on the ground, but the

number of days varies greatly from year to year.

The average relative humidity in midafternoon is

about 55 percent. Humidity is higher at night in all

seasons, and the average at dawn is about 80 percent.

The sun shines 70 percent of the time possible in

summer and 54 percent in winter. Prevailing winds are

southerly. Average windspeed is highest, 13 miles per

hour, in March.

Tornadoes and severe thunderstorms occur

occasionally but are local and of short duration.

Damage varies and is spotty. Hailstorms occur at times

during the warmer part of the year but in an irregular

pattern and only in small areas.

Settlement and Development

Cherokee Indians were the early settlers of the area

that now is Tulsa County. Land was allotted to the

Indians on the basis of its cash value; the largest

allotments were in areas of the rolling, timbered soils.

Land could also be leased for farming subject to the

supervision of the Indian agency. The sale or lease of

the land brought farmers into the county.

Most of these new settlers farmed a small

subsistence acreage. Cotton, grain sorghum, peanuts,

small grains, and alfalfa hay were the major cash

crops; other crops were grown only to feed horses,

mules, hogs, chickens, and beef and milk cattle. Some

farmers sold their land because they found that they

could not make a living on it. Farmers in other areas

acquired these lands, and farm units increased in size.

Farmers specialized in certain types of crop and

livestock enterprises to more efficiently manage larger

farm units. They became more mechanized, started

using irrigation to supplement moisture needs of field

crops, and converted old cultivated areas to tame

pasture.

One large reservoir was built on the Arkansas River

for municipal and industrial purposes. Some industries

were established.

Relief and Drainage

The soils of Tulsa County, except for those on the

panhandle, are predominantly nearly level to gently

sloping; more strongly sloping soils are along

drainageways. Soils in the panhandle in the western

part of the county are predominantly gently sloping

through steep. The general slope is from north to south.

The Arkansas and Caney Rivers drain most of the

county. Bird, Joe, Polecat, Hominy, Snake, Mingo, and

Duck Creeks are the main tributary streams. The rivers

and creeks have entrenched to a depth of about 20 to

100 feet.

Landforms in the county include prairies, woodlands,

and flood plains. The prairies and woodlands are on

divides between nearly level to gently sloping flood

plains, which range from 200 feet wide along the

smallest streams to about 3 miles wide along some of

the rivers. The slopes that extend into the flood plains

are strongly sloping through steep.

Natural Resources

The soil is one of the most important natural resources

in the county. It produces grass for livestock, timber,

crops, and mineral resources that are necessary to

sustain a substantial part of the economy in the county.

The water supply for the city of Tulsa comes mostly

from Spavinaw and Eucha Lakes in Delaware County,

Oklahoma. The water supply for suburban areas of

Tulsa and for other towns and communities comes

mainly from wells and small reservoirs. Hydroelectric

and flood-control reservoirs furnish recreation and

electricity. Farm ponds supply water for livestock.

Income from the sale of timber has been

considerably reduced in recent years. Most of the

timber has been culled, and the trees that were left to

propagate new stands are of poor quality. The timber is

used mostly for lumber.

Pockets of oil are scattered throughout the county.

Oil furnishes additional income and provides jobs for

the community.

Limestone is the most common surface mineral. It is

mined in the east-central part of the county for roads

and for industrial and commercial purposes.

Wildlife and game live outside of the metropolitan

area. Quail, dove, rabbit, and duck are hunted in

season. Fishing is mostly in the Keystone Reservoir,

the Arkansas River, and farm ponds.

In the survey area, sand is obtained from the soils

adjacent to the Arkansas River. Water-washed sand is

taken from the streambed.

A good mineral resource in the county is bituminous

coal. The coal fields, however, are mostly inactive.

The Keystone Reservoir, Arkansas River, and

numerous small ponds attract thousands of visitors

each year. Visitors are most numerous in the Keystone

Reservoir area during the spring and summer.

Transportation and Industry

Railroads, State and Federal highways, and county

roads form a network of transportation facilities in the
26

county. The Midland Valley and Atchison-Topeka and

Santa Fe Railroads transect the county north and

south, and the Missouri-Kansas-Texas and St. LouisSan Francisco Railroads furnish transit east and west.

U.S. Highway 64 and State Routes 51, 67, 33, and 20

extend east and west across the survey area, and U.S.

Highways 169 and 75 and State Routes 11 and 97 are

the main north-south roads. U.S. Highway 66 and

Interstate Highway 44 cross the county from southwest

to northeast. In farm areas, paved county roads provide

access to State and Federal highways.

Small grains, sorghum, vegetables, soybeans,

timber, and livestock are marketed in the county. Most

of the grain is shipped by rail or truck or through the

Port of Catoosa. Limestone is mined commercially in

the east-central part of the county. Most of the

industries are based on coal, oil, recreation, or

commerce and are located near Tulsa.

Formation and Classification of the Soils

This section relates the soils in this survey area to

the major factors of soil formation and describes the

system of soil classification. The classification and

extent of the soils in the survey area are shown in the

tables “Classification of the Soils” and “Acreage and

Proportionate Extent of the Soils,” which are at the end

of this section.

Formation of the Soils

In this section, the five major factors that affect the

formation of soils are described. Soil is produced by

the action of soil-forming processes on materials

deposited or accumulated by geologic agencies. The

characteristics of the soil at any given point are

determined by the physical and mineral composition of

the parent material; the climate under which the soil

material has accumulated and has existed since

accumulation; the plant and animal life on and in the

soil; the relief, or lay of the land; and the length of time

the forces of soil formation have acted on the parent

material.

Climate and vegetation are the active factors in soil

formation. They act on the parent material accumulated

through the weathering of rocks and slowly change it

into a natural body that has genetically related

horizons. The effects of climate and vegetation are

conditioned by relief. The parent material also affects

the nature of the profile and, in extreme instances,

determines most of its characteristics. Finally, time

is needed to change the parent material into a soil

profile. It may be much or little, but generally much

time is required to develop a profile that has distinct

horizons.

The five factors of soil formation are so closely

interrelated in their effects on the soil that few

generalizations can be made about the effect of any

one unless conditions are specified for the other four.

Many of the processes of soil development are

unknown.

Climate.—The climate of the survey area is

temperate and humid. Winds are southerly. Rainfall is

generally well distributed throughout the year, but dry

periods of 2 to 6 weeks occur during summer. The

average annual rainfall is about 36 inches and is

enough to support trees, which have contributed to soil

development in about 37 percent of the area. Intensive

rains, which commonly occur during spring, erode most

slopes. Erosion has occurred on most cultivated soils.

The average annual temperature is about 60 degrees

F, but extremes range from higher than 90 degrees to

less than 0 degrees. The frost-free season is about 215

days. Freezing and thawing have especially altered the

rock structure in the upper 2 feet of the soil, which

developed in sandstone material.

The climate is fairly uniform throughout the survey

area and is partly responsible for the dominance of

prairie grasses or trees. The influence of climate in

weathering the soil material and in developing horizons

is greatly altered by the effects on soil of parent

material, vegetation and animals, relief, time, and man.

Parent material.—Parent material is weathered,

unconsolidated rock or mineral material from which the

soil forms. In the formation of soils, parent material

affects color, texture, structure, natural fertility, and

other soil characteristics

Residuum and alluvium are two general kinds of

parent material in the survey area. On the prairie, soils

that formed in residuum were derived from shales,

sandstone, and limestone of the Pennsylvanian age.

Dennis, Eram, and Okemah soils formed mostly in

shales and sandstone material. Bates and Coweta

soils formed over sandstone. Bates soils have loamy,

clay-enriched horizons, and Coweta soils have a loamy

horizon that is shallow over sandstone.

Apperson, Catoosa, Lula, Newtonia, and Shidler

soils formed in loamy and clayey material over

limestone. Parsons and Pharoah soils formed in clayey

valley fill, which is alluvium. These soils have a clayenriched horizon that is similar to the parent material

but that has been strongly weathered. Also on the

prairie are the Okay soils, which formed in loamy

material on the uplands that parallel some of the large

streams in the county.

In wooded areas on uplands, the soils formed in

shale and sandstone. Darnell, Hector, and Linker soils

were derived from the sandstone, which is on most

ridges. Endsaw and Niotaze soils formed in clayey
28 Soil Survey Supplement of

parent material; they have a clayey subsoil, which

corresponds to the parent material.

In wooded areas on flood plains, the soils formed in

sandy, loamy, or clayey sediments. Kiomatia soils

formed mostly in sandy sediments, and Choska,

Cleora, Mason, Radley, Severn, Tullahassee, and

Wynona soils formed mostly in loamy alluvial

sediments. Latanier and Osage soils formed mostly in

clayey alluvium.

Plant and animal life.—Plants and animals are

active in soil formation. Plants and micro-organisms

grow in the weathered parent material and help break

down rock structure. They also produce organic

residue. As this residue is produced, an organic layer

(A horizon) is formed and gradually thickens.

The organic layer is the most fertile part of the soil.

In this layer, bacteria, fungi, and other micro-organisms

decompose organic matter, convert humus to simpler

forms, liberate plant nutrients, and fix nitrogen. Larger

organisms, such as the earthworms that are plentiful in

the soils, contribute to the translocation of plant

residue, to soil aeration, and to the development of soil

structure.

The kind and amount of vegetation regulate the

thickness of the A horizon. The kind of vegetation

depends largely on the moisture supply and on the

texture and acidity of the surface layer.

In wooded areas on uplands, the soils have a thin A

horizon, usually an E horizon, and they have a low or

medium base saturation. Darnell, Hector, Endsaw,

Glenpool, Kamie, Larton, Linker, and Niotaze soils are

examples.

In wooded areas on flood plains, the soils generally

have a thick, dark-colored A horizon because they

receive extra water for more plant growth. Timber on the

Kiomatia and Severn soils has added only a small

amount of organic matter because these soils are very

young and have a thin A horizon. Soils that are on flood

plains and that have a thick A horizon are Choska,

Cleora, Latanier, Osage, Radley, Tullahassee, and

Wynona soils.

The other soils in the county formed under native

grass and have a thick, dark A horizon. Large amounts

of plant residue and basic elements are returned to the

surface layer, since about one-third of the grass roots

die and are regrown each year. Soils on the prairie are

normally less acid than soils that formed under trees in

upland areas.

Relief.—Relief alters the effect of climate on soil

development and horizon formation. If the slope is

steep, runoff removes soil material almost as fast as it

forms, but if slope is gentle or nearly level, soil material

accumulates. For example, Parsons soils, which are

nearly level, are more developed than Dennis or Bates

soils, which are gently sloping on uplands. Parsons

soils receive additional water and have more water

percolating through the profile to influence loss, gain,

and transfer of soil constituents. They have lost clay,

iron, aluminum, and base elements from a bleached

eluvial (E) horizon. The eluvial horizon and the upper

clay-enriched (Bt) horizon are usually more acid and

have lower base saturation than horizons in most of the

other soils on the prairie. The accumulation of clay in

the clay-enriched horizon has become sufficient to

restrict internal drainage in Parsons soils and cause a

reversal in the leaching of basic elements. One of the

most easily leached elements, sodium, has begun to

accumulate; with time, Parsons soils may develop a

sodium-enriched Bt horizon similar to the one in

Pharoah soils.

The gently sloping Dennis soils, on uplands, have a

thicker and more clayey, clay-enriched (Bt) horizon

than the moderately deep Bates soils on similar slopes

primarily because their parent material is more

weatherable. Coweta soils are shallow over sandstone,

have more runoff and less accumulation of soil material

than Bates soils. Other soils on the uplands formed in

a manner similar to Parsons, Dennis, Bates, and

Coweta soils.

Relief also alters the effect of climate on soil

development and horizon formation in soils on flood

plains, which receive floodwater that contributes to the

thickening of the A horizon and to the high base

saturation. These soils have not had sufficient time to

develop a clay-enriched Bt horizon.

Time.—The length of time required for a soil to form

depends on the combined effects of other soil-forming

factors. The soils in the survey area range from

immature to old. The age of the soils is indicated by

the degree of horizon development. If the soil-forming

factors have not been active long enough for genetically

related horizons to form, the soils are considered

young or immature. Mature soils have genetically

related horizons, and old soils show advanced horizon

development or degradation of some horizon within the

pedon. Severn, Choska, and Coweta soils are

immature soils in Tulsa County; Dennis, Endsaw, and

Newtonia soils are considered mature soils, since they

have a Bt horizon. The old soils in the county, such as

Parsons soils, have developed an E horizon.

Classification of the Soils

The system of soil classification currently used was

adopted by the National Cooperative Soil Survey in

1965. Readers interested in further details about the

system should refer to the latest literature available

(USDA, 1993; USDA, 1998; and USDA, 1999).
Tulsa County, Oklahoma 29

The system of classification has six categories.

Beginning with the broadest, these categories are the

order, suborder, great group, subgroup, family, and

series. In this system the classification is based on the

different soil properties that can be observed in the field

or those that can be inferred either from other

properties that are observable in the field or from the

combined data of soil science and other disciplines.

The properties selected for the higher categories are

the result of soil genesis or of factors that affect soil

genesis. In the table “Classifications of the Soils,” the

soils of the survey area are classified according to the

system. Categories of the system are discussed in the

following paragraphs.

ORDER. Twelve soil orders are recognized as

classes in the system. The properties used to

differentiate among orders are those that reflect

the kind and degree of dominant soil-forming

processes that have taken place. Each order is

identified by a word ending in sol. An example is

Mollisol.

SUBORDER. Each order is divided into suborders

based primarily on properties that influence soil

genesis and are important to plant growth or that are

selected to reflect the most important variables within

the orders. The last syllable in the name of a suborder

indicates the order. An example is Udoll (Ud, meaning

himid, plus oll, from Mollisol).

GREAT GROUP. Each suborder is divided into great

groups on the basis of close similarities in kind,

arrangement, and degree of expression of pedogenic

horizons; soil moisture and temperature regimes; and

base status. Each great group is identified by the name

of a suborder and a prefix that suggests something

about the properties of the soil. An example is

Hapludolls (Hapl, meaning minimal horizonation, plus

udoll, the suborder of the Mollisols that has a udic

moisture regime).

SUBGROUP. Each great group may be divided into

three subgroups: the central (typic) concept of the

great groups, which is not necessarily the most

extensive subgroup; the intergrades, or transitional

forms to other orders, suborders, or great groups; and

the extragrades, which have some properties that are

representative of the great groups but do not indicate

transitions to any other known kind of soil. Each

subgroup is identified by one or more adjectives

preceding the name of the great group. An example is

Fluventic Hapludolls.

FAMILY. Families are established within a subgroup

on the basis of similar physical and chemical

properties that affect management. Among the

properties considered in horizons of major biological

activity below plow depth are particle-size distribution,

mineral content, temperature regime, thickness of the

soil penetrable by roots, consistence, moisture

equivalent, soil slope, and permanent cracks. A family

name consists of the name of a subgroup and a series

of adjectives. The adjectives are the class names for

SERIES. The series consists of soils that formed in

a particular kind of material and have horizons that,

except for texture of the surface soil or of the

underlying substratum, are similar in differentiating

characteristics and in arrangement in the soil profile.

Among these characteristics are color, texture,

structure, reaction, consistence, and mineral and

chemical composition.

Soil Series and Detailed Soil Map Units

In this section, each soil series shown on the

detailed soil maps at the back of this publication is

described. The descriptions, together with the soil

maps, can be useful in determining the potential of

managing a soil for food and fiber production; in

planning land use and developing soil resources; and in

enhancing, protecting, and preserving the environment.

Preceding the name of each map unit is the symbol

that identifies the unit on the detailed soil map. Each

map unit description includes general facts about the

soil and a brief description of the soil profile. In each

description, the principal hazards and limitations are

indicated and the management concerns and practices

needed are discussed.

A map unit represents an area on the landscape and

consists mostly of the soil or soils for which the unit is

named. Most of the delineations shown on the detailed

soil map are phases of soil series.

Soils that have profiles that are almost alike make

up a soil series. Except for allowable differences in

texture of the surface layer or of the underlying

substratum, all the soils of a series have major

horizons that are similar in extent of the component in

the map unit, thickness, and arrangement in the profile.

A soil series commonly is named for a town or

geographic feature near the place where a soil of that

series was first observed and mapped. All the soils in

the United States having the same series name have

essentially the same properties that affect their use

and their response to management practices.

Soils of one series can differ in texture of the surface

layer or in the underlying substratum and in slope,

erosion, stoniness, salinity, wetness, or other

characteristics that affect the use of the soils. On the

basis of such differences, a soil series is divided into

phases. The name of a soil phase commonly indicates

a feature that affects use or management. For

example, Dennis silt loam, 1 to 3 percent slopes, is

one of several phases within the Dennis series.

Some map units are made up of two or more

dominant kinds of soil. These areas are called

complexes. A complex consists of areas of two or more

soils that are so intricately mixed or so small in size

that they cannot be shown separately on the soil map.

Each area of a complex contains some of each of the

two or more dominant soils, and the pattern and

proportion are somewhat similar in all areas. DennisPharoah complex, 1 to 3 percent slopes, is an

example.

Most map units include small, scattered areas of

soils other than those that appear in the name of the

map unit. Some of these soils have properties that

differ substantially from those of the dominant soil or

soils and thus could significantly affect use and

management of the map unit. The soils that are

included in mapping are recognized in the description

of each map unit. Some of the more unusual or

strongly contrasting soils that are included are

identified by a special symbol on the soil map.

Most mapped areas include places that have little or

no soil material and support little or no vegetation.

Such places are called miscellaneous areas. They are

delineated on the soil map and given descriptive

names. Pits is an example. Some of these areas are

too small to be delineated and are identified by a

special symbol on the soil map.

The acreage and proportionate extent of each

mapping unit are given in the table “Acreage and

Proportionate Extent of the Soils,” and additional

information on properties, limitations, capabilities, and

potentials for many soil uses are given for each kind of

soil in other tables in this survey. (See “Summary of

Tables.”) Many of the terms used in describing soils are

defined in the Glossary.

Soil Properties

Data relating to soil properties are collected during

the course of the soil survey. The data and the

estimates of soil and water features, listed in tables,

are explained on the following pages.

Soil properties are determined by field examination

of the soils and by laboratory index testing of some

benchmark soils. Established standard procedures are

followed. During the survey, many shallow borings are

made and examined to identify and classify the soils

and to delineate them on the soil maps. Samples are

taken from some typical profiles and tested in the

laboratory to determine grain-size distribution,

plasticity, and compaction characteristics.

Estimates of soil properties are based on field

examinations, on laboratory tests of samples from the

survey area, and on laboratory tests of samples of

similar soils in nearby areas. Tests verify field

observations, verify properties that cannot be estimated

accurately by field observation, and help to

characterize key soils.

The estimates of soil properties shown in the tables

include the range of grain-size distribution and

Atterberg limits, the engineering classification, and the

physical and chemical properties of the major layers of

each soil. Pertinent soil and water features also are

given.

Engineering Index Properties

The table “Engineering Index Properties” gives

estimates of the engineering classification and of the

range of index properties for the major layers of each

soil in the survey area. Most soils have layers of

contrasting properties within the upper 5 or 6 feet.

Depth to the upper and lower boundaries of each

layer is indicated. The range in depth and information

on other properties of each layer are given in the series

descriptions section of this survey.

Texture is given in the standard terms used by the

U.S. Department of Agriculture. These terms are

defined according to percentages of sand, silt, and clay

in the fraction of the soil that is less than 2 millimeters

in diameter. “Loam,” for example, is soil that is 7 to 27

percent clay, 28 to 50 percent silt, and less than 52

percent sand. If the content of particles coarser than

sand is as much as 15 percent, an appropriate modifier

is added, for example, “gravelly.” Textural terms are

defined in the Glossary.

Classification of the soils is determined according to

the system adopted by the American Association of State

Highway and Transportation Officials (AASHTO, 2000)

and the Unified soil classification system (ASTM, 2001).

The Unified system classifies soils according to

properties that affect their use as construction material.

Soils are classified according to grain-size distribution

of the fraction less than 3 inches in diameter and

according to plasticity index, liquid limit, and organic

matter content. Sandy and gravelly soils are identified

as GW, GP, GM, GC, SW, SP, SM, and SC; silty and

clayey soils as ML, CL, OL, MH, CH, and OH; and

highly organic soils as PT. Soils exhibiting engineering

properties of two groups can have a dual classification,

for example, SP-SM.

The AASHTO system classifies soils according to

those properties that affect roadway construction and

maintenance. In this system, the fraction of a mineral

soil that is less than 3 inches in diameter is classified

in one of seven groups from A-1 through A-7 on the

basis of grain-size distribution, liquid limit, and

plasticity index. Soils in group A-1 are coarse grained

and low in content of fines (silt and clay). At the other

extreme, soils in group A-7 are fine grained. Highly

organic soils are classified in group A-8 on the basis of

visual inspection.

If laboratory data are available, the A-1, A-2, and A-7

groups are further classified as A-1-a, A-1-b, A-2-4,

A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additional

refinement, the suitability of a soil as subgrade material

can be indicated by a group index number. Group index

numbers range from 0 for the best subgrade material to

20 or higher for the poorest.

Rock fragments larger than 10 inches in diameter

and 3 to 10 inches in diameter are indicated as a

percentage of the total soil on a dry-weight basis. The

percentages are estimates determined mainly by

converting volume percentage in the field to weight

percentage.

Percentage (of soil particles) passing designated

sieves is the percentage of the soil fraction less than 3

inches in diameter based on an ovendry weight. The
100 Soil Survey Supplement of

sieves, numbers 4, 10, 40, and 200 (USA Standard

Series), have openings of 4.76, 2.00, 0.420, and 0.074

millimeters, respectively. Estimates are based on

laboratory tests of soils sampled in the survey area

and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits)

indicate the plasticity characteristics of a soil. The

estimates are based on test data from the survey area

or from nearby areas and on field examination.

The estimates of grain-size distribution, liquid limit, and

plasticity index are generally rounded to the nearest 5

percent. Thus, if the ranges of gradation and Atterberg

limits extend a marginal amount (1 or 2 percentage

points) across classification boundaries, the classification

in the marginal zone is omitted in the table.

116 Soil Survey Supplement of

Physical Properties

The table “Physical Properties of the Soils” shows

estimates of some characteristics and features that

affect soil behavior. These estimates are given for the

major layers of each soil in the survey area. The

estimates are based on field observations and on test

data for these and similar soils.

Depth to the upper and lower boundaries of each

layer is indicated. The range in depth and information

on other properties of each layer are given in the series

descriptions section of this survey.

Clay as a soil separate, or component, consists of

mineral soil particles that are less than 0.002 millimeter

in diameter. The estimated clay content of each major

soil layer is given as a percentage, by weight, of the

soil material that is less than 2 millimeters in diameter.

The amount and kind of clay greatly affect the

fertility and physical condition of the soil. They

determine the ability of the soil to adsorb cations and

to retain moisture. They influence shrink-swell

potential, permeability, plasticity, the ease of soil

dispersion, and other soil properties. The amount and

kind of clay in a soil also affect tillage and earth-moving

operations.

Moist bulk density is the weight of soil (ovendry) per

unit volume. Volume is measured when the soil is at

field moisture capacity, that is, the moisture content at

1

/3-bar moisture tension. Weight is determined after

drying the soil at 105 degrees C. In the table “Physical

Properties of the Soils,” the estimated moist bulk

density of each major soil horizon is expressed in

grams per cubic centimeter of soil material that is less

than 2 millimeters in diameter. Bulk density data are

used to compute shrink-swell potential, available water

capacity, total pore space, and other soil properties.

The moist bulk density of a soil indicates the pore

space available for water and roots. A bulk density of

more than 1.6 can restrict water storage and root

penetration. Moist bulk density is influenced by texture,

kind of clay, content of organic matter, and soil

structure.

Permeability (Ksat ) refers to the ability of a soil to

transmit water or air. The estimates indicate the rate of

downward movement of water when the soil is

saturated. They are based on soil characteristics

observed in the field, particularly structure, porosity,

and texture. Permeability is considered in the design of

soil drainage systems and septic tank absorption

fields.

Available water capacity refers to the quantity of

water that the soil is capable of storing for use by

plants. The capacity for water storage is given in inches

of water per inch of soil for each major soil layer. The

capacity varies, depending on soil properties that affect

the retention of water and the depth of the root zone.

The most important properties are the content of

organic matter, soil texture, bulk density, and soil

structure. Available water capacity is an important

factor in the choice of plants or crops to be grown and

in the design and management of irrigation systems.

Available water capacity is not an estimate of the

quantity of water actually available to plants at any

given time.

Linear extensibility refers to the change in length of

an unconfined clod as moisture content is decreased

from a moist to a dry state. It is an expression of the

volume change between the water content of the clod

at 1/3- or 1/10-bar tension (33kPa or 10kPa tension) and

oven dryness. The volume change is reported in the

table as percent change for the whole soil. Volume

change is influenced by the amount and type of clay

minerals in the soil.

Linear extensibility is used to determine the shrinkswell potential of soils. The shrink-swell potential is low

if the soil has a linear extensibility of less than 3

percent; moderate if 3 to 6 percent; high if 6 to 9

percent; and very high if more than 9 percent. If the

linear extensibility is more than 3, shrinking and

swelling can cause damage to buildings, roads, and

other structures and to plant roots. Special design

commonly is needed.

Organic matter is the plant and animal residue in the

soil at various stages of decomposition. In the table

“Physical Properties of Soils,” the estimated content of

organic matter is expressed as a percentage, by

weight, of the soil material that is less than 2

millimeters in diameter.

The content of organic matter in a soil can be

maintained or increased by returning crop residue to

the soil. Organic matter affects the available water

capacity, infiltration rate, and tilth. It is a source of

nitrogen and other nutrients for crops.

Erosion factors.—Soil erodibility (K) and soil-loss

tolerance (T) factors are used in an equation that

predicts the amount of soil lost through water erosion in

areas of cropland. The procedure for predicting soil loss

is useful in guiding the selection of soil and water

conservation practices.

Erosion factor K indicates the susceptibility of a soil

to sheet and rill erosion by water. Factor K is one of six

factors used in the Universal Soil Loss Equation

(USLE) to predict the average rate of soil loss by sheet

and rill erosion in tons per acre per year. The soil

properties that influence erodibility are those that affect

the infiltration rate, the movement of water through the

soil, and the water storage capacity of the soil and

those that allow the soil to resist dispersion, splashing,

abrasion, and the transporting forces of rainfall and

runoff. The most important soil properties are the

content of silt plus very fine sand, the content of sand

coarser than very fine sand, the content of organic

matter, soil structure, and permeability. The estimates

are modified by the presence of rock fragments. Values

of K range from 0.02 to 0.64. The higher the value, the

more susceptible the soil is to sheet and rill erosion.

Erosion factor Kf indicates the erodibility of the fineearth fraction, or the material less than 2 millimeters in

size. This is one of the factors used in the revised

Universal Soil Loss Equation.

Erosion factor T is an estimate of the maximum

annual rate of soil erosion by wind or water that can

occur over a sustained period without affecting crop

productivity. The rate is expressed in tons of soil loss

per acre per year. Ratings of 1 to 5 are used,

depending on soil properties and prior erosion. The

criteria used in assigning a T factor to a soil include

maintenance of an adequate rooting depth for crop

production, potential reduction of crop yields,

maintenance of water-control structures affected by

sedimentation, prevention of gullying, and the value of

nutrients lost through erosion.

Wind erodibility groups.—Wind erodibility is directly

related to the percentage of dry, nonerodible surface

soil aggregates larger than 0.84 millimeter in diameter.

From this percentage, the wind erodibility index factor

(I) is determined. This factor is an expression of the

stability of the soil aggregates, or the extent to which

they are broken down by tillage and the abrasion

caused by windblown soil particles. Soils are assigned

to wind erodibility groups (WEG) having similar

percentages of dry soil aggregates larger than 0.84

millimeter.

Wind erodibility groups are made up of soils that

have similar properties affecting their resistance to soil

blowing in cultivated areas. The groups indicate the

susceptibility to soil blowing. Soils are grouped

according to the following distinctions:

WEG 1. Very fine sand, fine sand, sand, and

coarse sand.

WEG 2. Loamy very fine sand, loamy fine sand,

loamy sand, loamy coarse sand, ash, and sapric

organic soil material.

WEG 3. Very fine sandy loam, fine sandy loam,

sandy loam, and coarse sandy loam.

WEG 4. Clay, silty clay, and noncalcareous clay

loam and silty clay loam with more than 35 percent

clay.

WEG 4L. Calcareous loam, silt loam, clay loam,

and silty clay loam characterized by a strongly or

violently effervescent reaction to cold dilute (1N) HCl.

WEG 5. Noncalcareous loam and silt loam with

less than 20 percent clay and sandy clay loam, sandy

clay, and hemic organic soil material.

WEG 6. Noncalcareous loam and silt loam with

more than 20 percent clay and noncalcareous clay

loam with less than 35 percent clay.

WEG 7. Silt, noncalcareous silty clay loam with less

than 35 percent clay, and fibric organic soil material.

WEG 8. Soils that are not susceptible to soil

blowing because of rock fragments on the surface or

because of surface wetness.

Wind erodibility index is a numerical value indicating

the susceptibility of soil to soil blowing, or the tons per

acre per year that can be expected to be lost to soil

blowing. There is a close correlation between soil

blowing and the size and durability of surface clods,

rock fragments, organic matter, and a calcareous

reaction. Soil moisture and frozen soil layers also

influence soil blowing.

Additional information about wind erodibility groups

and K, Kf, T, and I factors can be obtained from local

offices of the Natural Resources Conservation Service

or the Cooperative Extension Service.

126 Soil Survey Supplement of

Chemical Properties

The table “Chemical Properties of the Soils” shows

estimates of some characteristics and features that

affect soil behavior. These estimates are given for the

major layers of each soil in the survey area. The

estimates are based on field observations and on test

data for these and similar soils.

Depth to the upper and lower boundaries of each

layer is indicated. The range in depth and information

on other properties of each layer are given in the series

descriptions section of this survey.

Cation-exchange capacity is the total amount of

exchangeable cations that can be held by the soil,

expressed in terms of milliequivalents per 100 grams of

soil at neutrality (pH 7.0) or at some other stated pH

value. Soils having a low cation-exchange capacity hold

fewer cations and may require more frequent

applications of fertilizer than soils having a high cationexchange capacity. Soils having a high cationexchange capacity can retain cations. The ability to

retain cations helps to prevent the pollution of ground

water.

Soil reaction is a measure of acidity or alkalinity and

is expressed as a range in pH values. The range in pH

of each major horizon is based on many field tests. For

many soils, values have been verified by laboratory

analyses. Soil reaction is important in selecting crops

and other plants, in evaluating soil amendments for

fertility and stabilization, and in determining the risk of

corrosion.

Calcium carbonate equivalent is the percent of

carbonates, by weight, in the soil. The availability of

plant nutrients is influenced by the amount of

carbonates in the soil. Incorporating nitrogen fertilizer

into calcareous soils helps to prevent nitrite

accumulation and ammonium-N volatilization.

Gypsum is given as the percent, by weight, of

hydrated calcium sulfates in the soil. Gypsum is

partially soluble in water and can be dissolved and

removed by water. Soils that have a high content of

gypsum (more than 10 percent) may collapse if the

gypsum is removed by percolating water.

Salinity is a measure of soluble salts in the soil at

saturation. It is expressed as the electrical conductivity

of the saturation extract, in millimhos per centimeter

(decisiemens per meter) at 25 degrees C. Estimates

are based on field and laboratory measurements at

representative sites of nonirrigated soils. The salinity of

irrigated soils is affected by the quality of the irrigation

water and by the frequency of water application. Hence,

the salinity of soils in individual fields can differ greatly

from the value given in the table. Salinity affects the

suitability of a soil for crop production, the stability of

the soil if used as construction material, and the

potential of the soil to corrode metal and concrete.

Sodium adsorption ratio is the measure of sodium

(Na) relative to calcium (Ca) and magnesium (Mg) in

the water extract from saturated soil paste. It is the

ratio of the Na concentration divided by the square

root of one-half of the Ca + Mg concentration. Soils

having a sodium adsorption ratio of 13 or more may

be characterized by an increased dispersion of

organic matter and clay particles, reduced

permeability and aeration, and a general degradation

of soil structure.

Water Features

The table “Water Features” gives estimates of

various water features. The estimates are used in

land use planning that involves engineering

considerations.

Hydrologic soil groups are based on estimates of

runoff potential. Soils are assigned to one of four

groups according to the rate of water infiltration when

the soils are not protected by vegetation, are

thoroughly wet, and receive precipitation from longduration storms.

The four hydrologic soil groups are:

Group A. Soils having a high infiltration rate (low

runoff potential) when thoroughly wet. These consist

mainly of deep, well drained to excessively drained

sands or gravelly sands. These soils have a high rate of

water transmission.

Group B. Soils having a moderate infiltration rate

when thoroughly wet. These consist chiefly of

moderately deep or deep, moderately well drained or

well drained soils that have moderately fine texture to

moderately coarse texture. These soils have a

moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when

thoroughly wet. These consist chiefly of soils having a

layer that impedes the downward movement of water or

soils of moderately fine texture or fine texture. These

soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate

(high runoff potential) when thoroughly wet. These

consist chiefly of clays that have a high shrink-swell

potential, soils that have a high water table, soils that

have a claypan or clay layer at or near the surface, and

soils that are shallow over nearly impervious material.

These soils have a very slow rate of water

transmission.

If a soil is assigned to two hydrologic groups in the

table, the first letter is for drained areas and the second

is for undrained areas.

The months in the table indicate the portion of the

year in which the feature is most likely to be a concern.

Water table refers to a saturated zone in the soil.

The table “Water Features” indicates, by month, depth

to the top (upper limit) and base (lower limit) of the

saturated zone in most years. Estimates of the upper

and lower limits are based mainly on observations of

the water table at selected sites and on evidence of a

saturated zone, namely grayish colors or mottles

(redoximorphic features) in the soil. A saturated zone

that lasts for less than a month is not considered a

water table.

Ponding is standing water in a closed depression.

Unless a drainage system is installed, the water is

removed only by percolation, transpiration, or

evaporation. The table “Water Features” indicates

surface water depth and the duration and frequency of

ponding. Duration is expressed as very brief if less

than 2 days, brief if 2 to 7 days, long if 7 to 30 days,

and very long if more than 30 days. Frequency is

expressed as none, rare, occasional, and frequent.

None means that ponding is not probable; rare that it is

unlikely but possible under unusual weather conditions

(the chance of ponding is nearly 0 percent to 5 percent

in any year); occasional that it occurs, on the average,

once or less in 2 years (the chance of ponding is 5 to

50 percent in any year); and frequent that it occurs, on

the average, more than once in 2 years (the chance of

ponding is more than 50 percent in any year).

Flooding, the temporary inundation of an area, is

caused by overflowing streams, by runoff from adjacent

slopes, or by tides. Water standing for short periods

after rainfall or snowmelt is not considered flooding, and

water standing in swamps and marshes is considered

ponding rather than flooding.

Duration and frequency are estimated. Duration is

expressed as extremely brief if 0.1 hour to 4 hours,

very brief if 4 hours to 2 days, brief if 2 to 7 days, long

if 7 to 30 days, and very long if more than 30 days.

Frequency is expressed as none, very rare, rare,

occasional, frequent, and very frequent. None means

that flooding is not probable; very rare that it is very

unlikely but possible under extremely unusual weather

conditions (the chance of flooding is less than 1

percent in any year); rare that it is unlikely but possible

under unusual weather conditions (the chance of

flooding is 1 to 5 percent in any year); occasional that

it occurs infrequently under normal weather conditions

(the chance of flooding is 5 to 50 percent in any year);

frequent that it is likely to occur often under normal

weather conditions (the chance of flooding is more than

50 percent in any year but is less than 50 percent in all

months in any year); and very frequent that it is likely

to occur very often under normal weather conditions

(the chance of flooding is more than 50 percent in all

months of any year).

The information is based on evidence in the soil

profile, namely thin strata of gravel, sand, silt, or clay

deposited by floodwater; irregular decrease in organic

matter content with increasing depth; and little or no

horizon development.

Also considered are local information about the

extent and levels of flooding and the relation of each

soil on the landscape to historic floods. Information

on the extent of flooding based on soil data is less

specific than that provided by detailed engineering

surveys that delineate flood-prone areas at specific

flood frequency levels.

Water Features

(See text for definitions of terms used in this table. Estimates of the frequency of ponding and flooding apply to

 the whole year rather than to individual months. Absence of an entry indicates that the feature is not a

 concern or that data were not estimated.)

soil features. The estimates are used in land use

planning that involves engineering considerations.

A restrictive layer is a nearly continuous layer that

has one or more physical, chemical, or thermal

properties that significantly impede the movement of

water and air through the soil or that otherwise provide

an unfavorable root environment. Examples are

bedrock, cemented layers, dense layers, and frozen

layers. The table indicates the hardness and thickness

of the restrictive layer, both of which significantly affect

the ease of excavation. Depth to top is the vertical

distance from the soil surface to the upper boundary of

the restrictive layer.

Subsidence is the settlement of organic soils or of

saturated mineral soils of very low density. Subsidence

generally results from either desiccation and shrinkage

or oxidation of organic material, or both, following

drainage. Subsidence takes place gradually, usually

over a period of several years. The table shows the

expected initial subsidence, which usually is a result of

drainage, and total subsidence, which results from a

combination of factors.

Potential for frost action is the likelihood of upward

or lateral expansion of the soil caused by the formation

of segregated ice lenses (frost heave) and the

subsequent collapse of the soil and loss of strength on

thawing. Frost action occurs when moisture moves into

the freezing zone of the soil. Temperature, texture,

density, permeability, content of organic matter, and

depth to the water table are the most important factors

considered in evaluating the potential for frost action. It

is assumed that the soil is not insulated by vegetation

or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in

winter are the most susceptible to frost action. Well

drained, very gravelly, or very sandy soils are the least

susceptible. Frost heave and low soil strength during

thawing cause damage mainly to pavements and other

rigid structures.

Risk of corrosion pertains to potential soil-induced

electrochemical or chemical action that dissolves or

weakens uncoated steel or concrete. The rate of

corrosion of uncoated steel is related to such factors

as soil moisture, particle-size distribution, acidity, and

electrical conductivity of the soil. The rate of corrosion

of concrete is based mainly on the sulfate and sodium

content, texture, moisture content, and acidity of the

soil. Special site examination and design may be

needed if the combination of factors results in a severe

hazard of corrosion. The steel in installations that

intersect soil boundaries or soil layers is more

susceptible to corrosion than steel in installations that

are entirely within one kind of soil or within one soil

layer.

For uncoated steel, the risk of corrosion, expressed

as low, moderate, or high, is based on soil drainage

class, total acidity, electrical resistivity near field

capacity, and electrical conductivity of the saturation

extract.

For concrete, the risk of corrosion also is

expressed as low, moderate, or high. It is based on

soil texture, acidity, and amount of sulfates in the

saturation extract.

Agronomy

General management concerns affecting crops, hay

and pasture are identified in this section. The system of

land capability classification used by the Natural

Resources Conservation Service is explained, the

estimated yields of the main crops and hay and

pasture plants are listed for each soil, and the soils

that meet the requirements for prime farmland are

identified.

Planners of management systems for individual

fields or farms should consider obtaining specific

information from the local office of the Natural

Resources Conservation Service or the Cooperative

Extension Service.

Land Capability Classification

Land capability classification shows, in a general

way, the suitability of soils for most kinds of field crops.

Crops that require special management are excluded.

The soils are grouped according to their limitations for

field crops, the risk of damage if they are used for

crops, and the way they respond to management. The

criteria used in grouping the soils do not include major

and generally expensive landforming that would change

slope, depth, or other characteristics of the soils, nor

do they include possible but unlikely major reclamation

projects. Capability classification is not a substitute for

interpretations designed to show suitability and

limitations of groups of soils for rangeland, for

woodland, or for engineering purposes.

In the capability system, as described in “Land

Capability Classification” (USDA, 1961), soils generally

are grouped at three levels: capability class, subclass,

and unit. These levels indicate the degree and kinds of

limitations affecting mechanized farming systems that

produce the more commonly grown field crops, such as

corn, small grain, cotton, hay, and field-grown vegetables.

Only class and subclass are used in this survey.

Capability classes, the broadest groups, are

designated by Arabic numerals 1 through 8. The

numerals indicate progressively greater limitations and

narrower choices for practical use.

If properly managed, soils in classes 1, 2, 3, and 4

are suitable for the mechanized production of

commonly grown field crops and for pasture and

woodland. The degree of the soil limitations affecting

the production of cultivated crops increases

progressively from class 1 to class 4. The limitations

can affect levels of production and the risk of

permanent soil deterioration caused by erosion and

other factors.

Soils in classes 5, 6, and 7 are generally not suited

to the mechanized production of commonly grown field

crops without special management, but they are

suitable for plants that provide a permanent cover, such

as grasses and trees. The severity of the soil

limitations affecting crops increases progressively from

class 5 to class 7. The local office of the Natural

Resources Conservation Service or the Cooperative

Extension Service can provide guidance on the use of

these soils as cropland.

Areas in class 8 are generally not suitable for crops,

pasture, rangeland, or woodland. These areas may

have potential for other uses, such as recreational

facilities and wildlife habitat.

Capability subclasses identify the dominant kind of

limitation in the class. They are designated by adding

a small letter, e, w, s, or c, to the class numeral, for

example, 2e. The letter e shows that the main hazard

is the risk of erosion unless a close-growing plant

cover is maintained; w shows that water in or on the

soil interferes with plant growth or cultivation (in some

soils the wetness can be partly corrected by artificial

drainage); s shows that the soil is limited mainly

because it is shallow, droughty, or stony; and c, used

in only some parts of the United States, shows that

the chief limitation is climate that is very cold or very

dry.

There are no subclasses in class 1 because the

soils of this class have few limitations. Class 5

contains only the subclasses indicated by w, s, or c

because the soils in class 5 are subject to little or no

erosion. They have other limitations that restrict their

use mainly to pasture, rangeland, woodland, wildlife

habitat, or recreation.

The capability classification of each map unit is

given in the table “Land Capability and Yields per Acre

of Crops,” which is in this section.
152 Soil Survey Supplement of

Estimated Yields of Crops, Hay, and

Pasture

The average yields per acre that can be expected of

the principal crops and pasture under a high level of

management are shown in the tables “Land Capability

and Yields per Acre of Crops” and “Land Capability and

Yields per Acre of Pasture.” In any given year, yields

may be higher or lower than those indicated in the table

because of variations in rainfall and other climatic

factors. The land capability classification of each map

unit also is shown in the table.

The yields are based mainly on the experience and

records of farmers, conservationists, and extension

agents. Available yield data from nearby counties and

results of field trials and demonstrations are also

considered.

The management needed to obtain the indicated

yields of the various crops depends on the kind of soil

and the crop. Management can include drainage,

erosion control, and protection from flooding; the proper

planting and seeding rates; suitable high-yielding crop

varieties; appropriate and timely tillage; control of

weeds, plant diseases, and harmful insects; favorable

soil reaction and optimum levels of nitrogen,

phosphorus, potassium, and trace elements for each

crop; effective use of crop residue, barnyard manure,

and green manure crops; and harvesting that ensures

the smallest possible loss.

The estimated yields reflect the productive capacity

of each soil for each of the principal crops. Yields are

likely to increase as new production technology is

developed. The productivity of a given soil compared

with that of other soils, however, is not likely to change.

Crops other than those shown in the table are grown

in the survey area, but estimated yields are not listed

because the acreage of such crops is small.

Under good pasture management, proper grazing is

essential for the production of high-quality forage, stand

survival, and erosion control. Proper grazing helps

plants to maintain sufficient and generally vigorous top

growth during the growing season. Brush control is

essential in many areas, and weed control generally is

needed. Rotation grazing and renovation also are

important management practices.

A pasture program is needed to provide the desired

amount of forage during each month of the year. A

study of the growth habits of the different plants is

necessary to ensure adequate forage during each

month. The months that various kinds of forage plants

grow are indicated in Figure 2 in the “Range” section of

this survey (page 173). The percent growth that can be

safely grazed each month without substantially

reducing the total yield for each kind of plant is

illustrated.

Yield estimates are often indicated in animal unit

months (AUM), or the amount of forage or feed required

to feed one animal unit (one cow, one horse, one mule,

five sheep, or five goats) for 30 days.

The local office of the Natural Resources

Conservation Service or of the Cooperative Extension

Service can provide information about forage yields

other than those shown in the table “Land Capability

and Yields per Acre of Pasture.”

(Yields are those that can be expected under a high level of management. They are

 for nonirrigated areas. Absence of a yield indicates that the soil is not

 suited to the crop or the crop generally is not grown on the soil.)

Cropland Limitations and Hazards

The management concerns affecting the use of the

detailed map units in the survey area for crops are

shown in the table “Cropland Limitations and Hazards.”

The main concerns in managing nonirrigated cropland

are conserving moisture, controlling soil blowing and

water erosion, and maintaining soil fertility and tilth.

Conserving moisture primarily involves reducing the

evaporation and runoff rates and increasing the rate of

water infiltration. Applying conservation tillage and

conservation cropping systems, farming on the contour,

stripcropping, establishing field windbreaks, and leaving

crop residue on the surface conserve moisture.

Generally, a combination of several practices is

needed to control soil blowing and water erosion.

Conservation tillage, stripcropping, field windbreaks, tall

grass barriers, contour farming, conservation cropping

systems, crop residue management, diversions, and

grassed waterways help to prevent excessive soil loss.

Measures that are effective in maintaining soil

fertility include applying fertilizer, both organic and

inorganic, including manure; incorporating crop residue

or green manure crops into the soil; and using proper

crop rotations. Controlling erosion helps to prevent the

loss of organic matter and plant nutrients and thus

helps to maintain productivity, although the level of

fertility can be reduced even in areas where erosion is

controlled. All soils used for nonirrigated crops respond

well to applications of fertilizer.

On irrigated soils the main management concerns

are efficient water use, nutrient management, control of

erosion, soil tilth, pest and weed control, and timely

planting and harvesting for a successful crop. An

irrigation system that provides optimum control and

distribution of water at minimum cost is needed.

Overirrigation wastes water, leaches plant nutrients,

and causes erosion. Also, it can create drainage

problems, raise the water table, and increase soil

salinity.

Some of the limitations and hazards shown in the

table cannot be easily overcome. These are channels,

flooding, depth to rock, ponding, gullies, and lack of

timely precipitation.

Additional limitations and hazards are as follows:

Areas of rock outcrop and oil waste land.—Farming

around these areas may be feasible. Subsoiling or

deep ripping soft sedimentary beds increases the

effective rooting depth and the rate of water infiltration.

Excessive permeability.—This limitation causes

deep leaching of nutrients and pesticides. The

capacity of the soil to retain moisture for plant use is

poor.

Potential for ground-water pollution.—This is a

hazard in soils with excessive permeability, hard

bedrock, or a water table within the profile.

Lime content, limited available water capacity, poor

tilth, restricted permeability, and surface crusting.—The

adverse effects of these limitations can be reduced by

incorporating green manure crops, manure, or crop

residue into the soil; applying a system of conservation

tillage; and using conservation cropping systems. Also,

crops may respond well to additions of phosphate

fertilizer to soils that have a high content of lime.

Surface rock fragments.—This limitation causes

rapid wear of tillage equipment. It cannot be easily

overcome.

Slope.—Where the slope is more than 8 percent,

water erosion and soil blowing may be accelerated

unless conservation farming practices are applied.

Surface stones.—Stones or boulders on the surface

can hinder normal tillage unless they are removed.

Salt and sodium content.—In areas where this is a

limitation, only salt- and sodium-tolerant crops should

be grown.

Criiteria for Limitations and Hazards

Following is an explanation of the criteria used to

determine the limitations or hazards.

Areas of rock outcrop.—Rock outcrop is a named

component of the map unit.

Areas of rubble land.—Rubble land is a named

component of the map unit.

Areas of oil waste land.—Oil waste land is a named

component of the map unit.

Channeled.—The word “channeled” is included in the

name of the map unit.

Depth to rock.—Bedrock is within a depth of 40

inches.

Water erosion.—The surface K factor multiplied by

the upper slope limit is more than 2 (same as prime

farmland criteria).

Excessive permeability.—The upper limit of the

permeability range is 6 inches or more within the soil

profile.

Flooding.—The component of the map unit is

occasionally flooded or frequently flooded.

Gullied.—The word “gullied” is included in the name

of the map unit.

Lime content.—The surface layer has more than 15

percent calcium carbonate equivalent or has a wind

erosion equation of 4L.

Limited available water capacity.—The available

water capacity calculated to a depth of 60 inches or to

a root-limiting layer is 6 inches or less.
162 Soil Survey Supplement of

Ponding.—A ponding duration is assigned to the

component of the map unit.

Potential for ground-water pollution.—The soil has a

water table within a depth of 4 feet or bedrock within 40

inches of the surface, or permeability is more than 2

inches per hour within the soil profile.

Poor tilth.—The component of the map unit has

more than 35 percent clay in the surface layer.

Restricted permeability.—Permeability is 0.06 inch

per hour or less within the soil profile.

Salt content.—The component of the map unit has

an electrical conductivity of more than 4 in the surface

layer or more than 8 within a depth of 30 inches.

Slope.—The upper slope limit of the component of

the map unit is more than 8 percent.

Sodium content.—The sodium adsorption ratio of the

component of the map unit is more than 13 within a

depth of 30 inches.

Soil blowing.—The wind erodibility index is equal

to or greater than 8.

Surface rock fragments.—The terms describing the

texture of the surface layer include any rock fragment

modifier except for gravelly or channery.

Surface crusting.—The organic matter content is

less than 2 percent in the surface layer.

Surface stones.—The terms describing the texture

of the surface layer include any stony or bouldery

modifier, or the map unit is a stony or bouldery phase.

Water table.—The component of the map unit has a

water table within a depth of 3 feet.

Prime Farmland

Prime farmland is of major importance in meeting

the Nation’s short- and long-range needs for food and

fiber. The acreage of high-quality farmland is limited,

and the U.S. Department of Agriculture recognizes that

government at local, State, and Federal levels, as well

as individuals, must encourage and facilitate the wise

use of our Nation’s prime farmland.

Prime farmland soils, as defined by the U.S.

Department of Agriculture, are soils that are best suited

to food, feed, forage, fiber, and oilseed crops. Such

soils have properties that favor the economic production

of sustained high yields of crops. The soils need only

to be treated and managed by acceptable farming

methods. An adequate moisture supply and a

sufficiently long growing season are required. Prime

farmland soils produce the highest yields with minimal

expenditure of energy and economic resources, and

farming these soils results in the least damage to the

environment (USDA, 2002).

Prime farmland soils may presently be used as

cropland, pasture, rangeland, or woodland or for other

purposes. They either are used for food and fiber or are

available for these uses. Urban or built-up land, public

land, and water areas cannot be considered prime

farmland. Urban or built-up land is any contiguous unit

of land 10 acres or more in size that is used for such

purposes as housing, industrial, and commercial sites,

sites for institutions or public buildings, small parks,

golf courses, cemeteries, railroad yards, airports,

sanitary landfills, sewage treatment plants, and watercontrol structures. Public land is land not available for

farming in National forests, National parks, military

reservations, and State parks.

Prime farmland soils commonly receive an

adequate and dependable supply of moisture from

precipitation or irrigation. The temperature and growing

season are favorable, and the level of acidity or

alkalinity and the content of salts and sodium are

acceptable. The soils have few, if any, rocks and are

permeable to water and air. They are not excessively

erodible or saturated with water for long periods, and

they are not frequently flooded during the growing

season or are protected from flooding. Slopes range

from 0 to 8 percent.

Soils that have a high water table, are subject to

flooding, or are droughty may qualify as prime

farmland where these limitations are overcome by

drainage measures, flood control, or irrigation.

Onsite evaluation is necessary to determine the

effectiveness of corrective measures. More information

about the criteria for prime farmland can be obtained

at the local office of the Natural Resources

Conservation Service.

A recent trend in land use has been the conversion

of prime farmland to urban and industrial uses. The loss

of prime farmland to other uses puts pressure on lands

that are less productive than prime farmland.

About 126,000 acres, or nearly 34 percent of the

survey area, meets the requirements for prime

farmland. The map units in the survey area that meet

the requirements for prime farmland are listed in the

table “Prime Farmland.” The location of each map unit

is shown on the detailed soil maps at the back of this

publication. The soil qualities that affect use and

management are described in the section “Soil

Series and Detailed Soil Map Units.” This list does

not constitute a recommendation for a particular

land use.

Range

Mark Moseley, range conservationist, Natural Resources

Conservation Service, Stillwater, helped prepare parts of this

section.

Range, grazed forest land, and native pasture

provide forage for livestock in the survey area.

Range is defined as land on which the native

vegetation (the climax, or natural potential, plant

community) is predominantly grasses, grasslike plants,

forbs, and shrubs suitable for grazing and browsing.

Range includes natural grasslands, savannas, many

wetlands, some deserts, tundra, and certain shrub and

forb communities. Range receives no regular or

frequent cultural treatment. The composition and

production of the plant community are determined by

soil, climate, topography, overstory canopy, and

grazing management.

Grazed forest land is defined as land on which the

understory includes, as an integral part of the forest

plant community, plants that can be grazed without

significant impairment of other forest values.

Native pasture is defined as land on which the

potential (climax) vegetation is forest but which is used

and managed primarily for the production of native

forage plants. Native pasture includes cutover forest

land and forest land that has been cleared and is

managed for native or naturalized forage plants.

The table “Rangeland Productivity and Characteristic

Plant Communities” in this section shows, for each

soil, the ecological site; the total annual production of

vegetation in favorable, normal, and unfavorable years;

the characteristic vegetation; and the average

percentage of each species. Only those soils that are

used as rangeland or are suited to use as rangeland

are listed. Explanation of the column headings in this

table follows.

About 11 percent of the soils in Tulsa County are in

native range on which domestic animals graze. The

range is generally grazed throughout the year, but the

forage is supplemented by protein and hay or tame

pasture.

Most of the local ranches and livestock farms are

cow-calf operations. There are some pure stocker

enterprises and some ranchers that diversify their cowcalf operation with stockers to provide greater flexibility.

Several livestock operations supplement the grazing

of native rangeland with introduced grasses such as

bermudagrass and ‘Plains’ bluestem. Forage crops are

also used. Protein, hay, and small grain crops are used

to supplement livestock through winter.

Droughts occur in varying lengths and short-term

summer droughts are common. Longer periods of

drought, some lasting several months, also happen

frequently.

The pre-settlement vegetation evolved with periodic

natural fires, droughts, migratory grazing by bison, and

impact from many other wildlife species. The bison

would heavily impact an area and then move to other

grazing range.

Early settlement brought continuous grazing and

eliminated much of the high-quality vegetation on some

range sites. Areas that were once open savannah range

sites with a mixture of grasses, forbs, and scattered

trees, are now covered with oak, a few tall and mid

grasses, and low successional grasses and forbs.

Some prairie sites are now growing low successional

grasses and forbs instead of tall grasses. The amount

of forage presently produced may be less than half of

that originally produced. Eastern redcedar has

increased significantly on some sites due to the lack of

prairie fires.

However, remnants of the original plant species are

still found on most rangeland and progressive grazing

management will allow these high quality plants to

reestablish without reseeding.

An ecological site for rangeland is a distinctive kind

of land and vegetation with specific physical

characteristics that makes it different from other kinds

of land in its ability to produce a distinctive kind and

amount of vegetation.

There are many different ecological sites in Tulsa

County. Over historical time, the combination of plants

best suited to a particular soil and climate became

dominant. If the soil is not excessively disturbed, this

group of plants is the natural plant community for the

site. Natural plant communities are not static but vary

slightly from year to year and place to place.

The relationship between soils and vegetation was

ascertained during this survey; thus, ecological sites
172 Soil Survey Supplement of

generally can be determined directly from the soil map.

Soil properties that affect moisture supply and plant

nutrients have the greatest influence on the productivity

of range plants. Soil reaction, salt content, and a

seasonal high water table are also important. The “Field

Office Technical Guide,” which is available at local

offices of the Natural Resources Conservation Service,

can provide specific information about ecological sites.

Total dry-weight production is the amount of

vegetation that can be expected to grow annually on

well managed rangeland. It includes all vegetation,

whether or not it is palatable to grazing animals. It

includes the current year’s growth of leaves, twigs, and

fruit of woody plants, It does not include the increase in

stem diameter of trees and shrubs. It is expressed in

pounds per acre of air-dry vegetation for favorable,

normal, and unfavorable years. In a favorable year, the

amount and distribution of precipitation and the

temperatures make growing conditions substantially

better than average. In a normal year, growing

conditions are near the historical monthly average. In

an unfavorable year, growing conditions are well below

average, generally because of low available soil

moisture. Figure 2 shows a typical growth curve for

native vegetation and other forage that represents the

percentage of total growth that occurs each month.

Dry weight is the total annual yield per acre of air-dry

vegetation. Yields are adjusted to a percent of air-dry

moisture content. The relationship of green weight to

air-dry weight varies according to such factors as stage

of maturity, exposure, amount of shade, recent rains,

and unseasonable dry periods.

Characteristic vegetation consists of the grasses,

forbs, and shrubs that make up most of the potential

natural plant community on each soil. The plants are

listed by common name. Under composition, the

anticipated percentage of the total annual production is

given for each species making up the characteristic

vegetation. The amount that can be used as forage

depends on the kinds of grazing animals and on the

grazing season.

Similarity Index

Similarity index indicates, by percentages ranging

from 1 to 100, the extent to which the present plant

community resembles one of two other plant

communities on an ecological site. The Natural

Resources Conservation Service uses similarity index

two ways.

The first is to use similarity index to compare the

present vegetation on an ecological site to the presumed

historic vegetation for that site. This comparison provides

a basis to the client for knowing the extent and direction

of changes that have taken places between current

vegetation and historic vegetation.

A similarity index of 70 would suggest that the

present plant community contain 70 percent of the

presumed historic plant community for that site.

The second is to use similarity index, as a measure

of how near the current plant community is to the

landowners goal for the land. The management goal for

rangeland is not necessarily a similarity index of 100

as compared to the historic plant community.

Therefore, the similarity index can represent the

percentage of the plant community that resembles a

desired plant community.

Abnormal disturbances that change the natural plant

community include repeated overuse by livestock,

excessive burning, erosion, and cultivation. Grazing

animals select the most palatable plants. These plants

will eventually die if they are continually grazed at a

severity that does not allow for recovery. A very severe

disturbance can completely destroy the natural

community. Under these conditions, the less desirable

plants, such as annuals and weed-like plants, can

increase. If the plant community and the soils have not

deteriorated significantly, it eventually can return to

predominantly natural plants if proper range

management is applied.

Knowledge of the ecological site is necessary as a

basis for planning and applying the management

needed to maintain or improve the desired plant

community for selected uses. Such information is

needed to support management objectives, planned

grazing systems, stocking rates, suitable wildlife

management practices, potential for recreational uses,

and condition of watersheds.

Range Management

Range management requires a knowledge of the

kinds of soil and of the potential natural plant

community. It also requires an evaluation of the

similarity index.

Effective range management conserves rainfall,

enhances water quality, reduces the hazard of

downstream flooding, improves yields, provides forage

for livestock and wildlife, enhances recreational

opportunities, and protects the soil. The main

management concern is recognizing important changes

in the plant cover or rhe range trend. These changes

take place gradually and can be overlooked.

Each range manager should evaluate the type of

plant community that best supports the ranch and then

apply management and ecological principles to achieve

the goals. The desired plant community should be

within the capabilities of the land.
Tulsa County, Oklahoma 173

The primary range management practices used in

Tulsa County include prescribed grazing, stock-water

developments, and fences. If undesirable plants

become dominant, range seeding, brush management,

or prescribed burning are commonly used.

Range management includes four major

considerations:

1. Proper grazing distribution, which is achieved by

managing livestock to graze all parts of the grazing unit

equally.

2. Selective grazing, which occurs because

animals graze preferred plants to balance their diets. If

selective grazing occurs repeatedly, the preferred

plants are damaged.

3. A proper stocking rate, which is achieved by

balancing animal numbers with forage production.

4. Rest periods during which grazed plants are

given enough rest to recover and to maintain their

growth.

It is important to remember that forage production is

controlled by rainfall while composition is determined

by grazing management.

Setting the stocking rate is not an exact science

because there are influences from grazing management

systems, season of use, mix of livestock, and seasonal

forage production. Some rules of thumb, however, can be

helpful. To maintain a nutritional cover of plants, about 50

percent, of the annual growth of the key or most

important grazing plants, should remain at the end of the

grazing season. Plants can be removed not only through

grazing by livestock but also through grazing by rodents,

insects, and wildlife and through the deterioration

caused by climatic variations. Because of these factors,

a safe initial stocking rate for livestock should be

calculated on the basis of 25 percent of the total annual

growth, by weight, of the vegetation.

For example, production on the loamy prairie range

site with a similarity index above 70 to the historic plant

community for an average season could be 3,500

pounds per acre of air-dry grasses, forbs, and limited

woody species. Twenty five percent of this is 875

pounds per acre.

A 1,000-pound cow and her calf is equivalent to one

animal unit (AU) and will consume about 2.6 percent of

her body weight (26 pounds) of forage per day. So, in

one month, an animal unit will consume 790 pounds of

native vegetation, depending on the quality and stage of

growth of the plants (26 pounds per day times 365

days per year divided by 12 months per year).

Dividing 875 pounds (forage allocation) by 26 pounds

(forage required per day for one animal unit) suggests

that 1 acre of loamy prairie range site with a similarity

Figure 2.—Forage calendar showing the estimated monthly percentage of growth on an annual basis for forage

production.
174 Soil Survey Supplement of

index of 70 will feed one cow for 33.6 days. To convert

forage available from 1 acre to animal unit months

(AUM), the available forage (875 pounds) is divided by

the amount required to feed an animal unit for 1 month

(790 pounds). One acre will provide 1.1 AUM of grazing.

Therefore, 10.9 acres will feed one cow for 12 months

in this example. Another approach is to calculate the

annual forage needs of an animal unit (790 pounds per

month times 12 months equals 9490 pounds). Dividing

the 875 pounds of usable forage per acre into the 9490

pounds needed by the cow reveals that approximately

10.9 acres is needed for one cow annually. Stocking

rate calculation should be adjusted for animal size,

grazing system, and grazing season.

More information about planning a grazing program

is available from the local office of the Natural

Resources Conservation Service.

Ecological Sites

Twelve ecological sites are recognized in Tulsa

County. The ecological site identifier has ten

characters. The first four characters identify the major

land resource area, the fifth character identifies the

major land resource unit subdivision, the next three

characters identify the individual ecological site

number, and the final two characters identify the state.

This is followed by the proper name for the ecological

site. The following descriptions list the plants that are

characteristic of the sites. Detailed ecological site

descriptions are available at the local office of the

Natural Resources Conservation Service.

112XY059OK, Loamy Prairie (northeast).—This

site is in areas where climax plant cover is primarily

true prairie grasses such as big bluestem, little

bluestem, Indiangrass, and switchgrass. These plants

make up about 80 percent of the vegetation. Plants

such as jointtail, purpletop, and dropseeds make up to

30 percent of the vegetation. Those plants that invade

when pastures decline include broomsedge, splitbeard,

windmillgrass, silver bluestem, and buffalograss.

Weedy invaders are western and lanceleaf ragweed,

narrowleaf sumpweed, broomweed, and ironweed.

084AY075OK, Sandy Savannah (west).—This site

is in areas of deep, gently sloping to steep, moderately

productive, loamy, upland soil. Under good

management the important plants are a scattered

stand of post oak and blackjack oak with little

bluestem, big bluestem, Indiangrass, perennial

sunflowers, and perennial lespedezas. Continued

abuse will result in an increase of poison ivy, tall

dropseed, sideoats grama, Scribner panicum,

purpletop, and heathaster. Woody vegetation is

approximately 10 to 15 percent of the total.

112XY077OK, Sandy Savannah.—This site is in

areas where the principal plants are little bluestem,

Indiangrass, big bluestem, and switchgrass. These

plants represent about 40 percent of the climax cover.

Other warm-season grasses include purpletop,

sideoats grama, bearded skeletongrass, and tall

dropseed. Cool-season plants include Canada wildrye,

Virginia wildrye, Texas bluegrass, and flatsedge

species. Virginia tephrosia, slender lespedeza,

roundhead lespedeza, trailing lespedeza, and tickclover

are important legumes. Woody species compose about

25 percent of the cover such as post oak, blackjack

oak, hickory, ash, elm, bumelia, coralberry, greenbrier,

poison-ivy, Virginia creeper, and grape. Plants such as

broomsedge bluestem, splitbeard bluestem, fringeleaf

paspalum, Japanese brome threeawns, partridgepea,

ragweeds, croton, bitter sneezeweed, persimmon, and

hawthorn dominate when the site is abused.

118XY075OK, Sandy Savannah.—This site is in

areas of mixed tall grasses and low grade hardwoods

with some scrub pine. Principal grasses are big

bluestem, Indiangrass, little bluestem, and switchgrass

in approximately that order of dominance. These

grasses represent about half of the total original cover.

Principal cool-season plants are Canada and Virginia

wildrye, low panicums, and sedges. Woody species

comprise about 30 percent of the vegetation. The main

species are post oak, blackjack oak, southern red oak,

hickory, persimmon, and sassafras, grading into pine

and hardwood forest at about 45 inches of precipitation.

084AY079OK, Savannah Breaks.—This site is in

areas of mid-tall grasses and oak-hickory climax. Big

bluestem, little bluestem, and Indiangrass compose

about 40 to 50 percent of the total vegetation. The

canopy of woody species will generally constitute 15 to

20 percent. Abuse caused by overgrazing results in a

gradual thickening of the woody species and a

corresponding reduction in grass. The taller grasses

are restricted to the deeper soils while low growing

perennials and annual grasses will occupy the very

shallow soils. Hairy grama, Scribner panicum, and

several muhly grasses, including rock, threeawn, and

nimblewill are typical of the low growing type

vegetation.

112XY010OK, Claypan Prairie.—The potential

plant community for this site is a tall grass aspect.

Species composition, by weight, is 80 percent grasses,

15 percent forbs, and 5 percent woody plants. Big

bluestem, Indiangrass, switchgrass, little bluestem,

prairie scurfpea, Illinois bundleflower, leadplant,

blacksampson, gay feathers, and poison-ivy are plants

that make up 70 percent of production in high

ecological condition. Under continuous heavy grazing,

These plants are replaced by meadow dropseed,
Tulsa County, Oklahoma 175

sideoats grama, Scribner panicum, fringeleaf

paspalum, buffalograss, wild indigo, ashy sunflower,

milkweeds, sagewort, goldenrods, wingedelm, and

sumacs. As the site deteriorates, plants such as

broomsedge bluestem, splitbeard bluestem, silver

bluestem, windmillgrass, threeawns, Japanese brome,

showy partridgepea, ragweeds, croton, bitter

sneezeweed, persimmon, and hawthorn dominate the

site.

112XY086OK, Shallow Prairie (eastern).—Little

bluestem, big bluestem, Indiangrass, and switchgrass

comprise 50 to 60 percent of the vegetation on this

site. Meadow dropseed, sideoats grama, and Scribner

panicum increase on the deeper soils under continuous

grazing. Important legumes are catclaw sensitive brier,

Illinois bundleflower, Virginia tephrosia, leadplant, and

priairieclover. Woody species occur in minor amounts

including coralberry, hackberry, wingedelm, and

persimmon. These species increase when the site is

abused.

084AY088OK, Shallow savannah.—This site is in

areas of mid-tall grass savannahs. Little bluestem,

sand bluestem, and sideoats grama are the more

important grasses. Sideoats grama is important on the

very shallow spots. Decreaser grasses and legumes

make up about 50 percent of the climax vegetation.

Principal legumes are Stueve’s lespedeza, roundhead

lespedeza, Virginia tephrosia, and prairieclover. Post

oak, blackjack oak, and associated woody species

represent about 10 percent of climax. Buckeye, a

common woody shrub that is sometimes poisonous to

livestock, occurs on this site.

118XY088OK, Shallow Savannah.—This site

produces an open stand of post oak, blackjack oak,

and associated hardwoods, with an understory of tall

grasses. Oak species average 15 to 20 percent of the

composition. Big bluestem, little bluestem, and

Indiangrass compose about 70 percent of the

production, with other grasses and brush making up

about 10 to 15 percent. When the site condition

declines, grasses thin out and are replaced by oak

sprouts. The site may develop the appearance of a

forest; however, the brush will not reach commercial

woodland size. Shortleaf pine is found on the dry edge

of the humid zone but is sub-marginal for woodland

products, since it occurs in a rangeland area (not a

forest site).

112XY098OK, Very Shallow.—On this site,

moisture and root penetration are very limited and

result in a varied plant community. Drought-tolerant

grasses such as blue, sideoats, and hairy grama

predominate. Bands of deeper soils support tall

grasses such as big bluestem, Indiangrass, little

bluestem, and switchgrass. Annual grasses, along with

perennial forbs such as cobea penstemon, willowleaf

sunflower, and dotted gay feather are abundant during

years of normal rainfall.

118XY020OK, Deep Sand Savannah.—This site

supports a vegetative cover composed of 75 percent

grasses and forbs, along with a 25 percent crown

canopy of woody species. Forage species are 80

percent climax species with the principal ones being

big bluestem, sand bluestem, Indiangrass, little

bluestem, switchgrass, broadleaf uniola, beaked

panicum, and sand lovegrass. Other plants that

increase with prolonged mismanagement are

broomsedge bluestem, splitbeard bluestem, showy

partridgepea, bitter sneezeweed, ragweeds, and white

snakeroot. Principal woody species are post oak,

blackjack oak, winged elm, and persimmon.

112XY856OK, Reseeded Loamy Prairie.—This

site is in areas where seeded species include tall

grasses such as little bluestem, big bluestem,

Indiangrass, switchgrass, sideoats grama, Illinois

bundleflower, and a few others. Under continuous

heavy grazing, they are replaced by plants such as

dropseed, Scribner panicum, wildindigo, heath aster,

goldenrod, sagewort, sumacs, and blackberry. If the

site continues to deteriorate, plants such as

broomsedge, splitbeard bluestem, silver bluestem,

Japanese brome, threeawn, showy partridgepea,

broomweed, ragweed, croton, and persimmon dominate

the site. Because of cultivation, this site is not as

productive as the original plant community.

Windbreaks and Environmental Plantings

Windbreaks protect livestock, buildings, and yards

from wind and snow. They also protect fruit trees and

gardens, and they furnish habitat for wildlife. Several

rows of low- and high-growing broadleaf and coniferous

trees and shrubs provide the most protection.

Field windbreaks are narrow plantings made at right

angles to the prevailing wind and at specific intervals

across the field. The interval depends on the erodibility

of the soil. Field windbreaks protect cropland and crops

from wind, help to keep snow on the fields, and provide

food and cover for wildlife.

Environmental plantings help to beautify and screen

houses and other buildings and to abate noise. The

plants, mostly evergreen shrubs and trees, are closely

spaced. To ensure plant survival, a healthy planting

stock of suitable species should be planted properly on

a well prepared site and maintained in good condition.

Windbreaks are often planted on land that did not

originally support trees. Knowledge of how trees

perform on such land can be gained only by observing

and recording the performance of trees that have been

planted and have survived. Many popular windbreak

species are not indigenous to the areas in which they

are planted.

Each tree or shrub species has certain climatic and

physiographic limits. Within these parameters, a tree

or shrub may grow well or grow poorly, depending on

the characteristics of the soil. Each tree or shrub has

definable potential heights in a given physiographic

area and under given climatic conditions. Accurate

definitions of potential heights are necessary when a

windbreak is planned and designed.

The table “Windbreaks and Environmental Plantings”

shows the height that locally grown trees and shrubs

are expected to reach in 20 years on various soils. The

estimates in this table are based on measurements

and observation of established plantings that have been

given adequate care. They can be used as a guide in

planning windbreaks and screens. Additional

information on planning windbreaks and screens and

planting and caring for trees and shrubs can be

obtained from local offices of the Natural Resources

Conservation Service or the Cooperative Extension

Service or from a local nursery.

Wildlife Habitat

Soils affect the kind and amount of vegetation that

is available to wildlife as food and cover. They also

affect the construction of water impoundments. If

food, cover, or water is missing, inadequate, or

inaccessible, wildlife will be scarce or will not inhabit

the area.

The table “Wildlife Habitat” in this section shows the

soils that have potential for habitat development.

Wildlife habitat can be created or improved by planting

appropriate vegetation, properly managing the existing

plant cover, and fostering the natural establishment of

desirable plants.

Elements of Wildlife Habitat

The elements of wildlife habitat are described in the

following paragraphs.

Grain and seed crops are domestic grains and seedproducing herbaceous plants used by wildlife.

Examples are wheat, rye, oats, and barley.

Grasses and legumes are domestic perennial

grasses and herbaceous legumes planted for wildlife

food and cover. Examples are fescue, bromegrass,

timothy, orchardgrass, clover, alfalfa, trefoil, reed

canarygrass, and crownvetch.

Wild herbaceous plants are native or naturally

established grasses and forbs, including weeds, that

provide food and cover for wildlife. Examples are

bluestem, Indiangrass, blueberry, goldenrod,

lambsquarters, dandelions, blackberry, ragweed,

wheatgrass, fescue, and nightshade.

The major soil properties affecting the growth of grain

and forage crops and wild herbaceous plants are depth

of the root zone, texture of the surface layer, the

amount of water available to plants, wetness, salinity or

sodicity, and flooding. The length of the growing season

also is important.

Hardwood trees and woody understory produce nuts

or other fruit, buds, catkins, twigs, bark, and foliage

that wildlife eat. Examples are oak, poplar, boxelder,

birch, maple, green ash, willow, and American elm.

Examples of fruit-producing shrubs that are suitable for

planting on soils that have good potential for these

plants are hawthorn, honeysuckle, American plum,

Redosier dogwood, chokecherry, serviceberry, silver

buffaloberry, and crabapple.

Coniferous plants are cone-bearing trees, shrubs, or

ground cover that provides habitat or supplies food in

the form of browse, seed, or fruitlike cones. Examples

are pine, spruce, hemlock, fir, yew, cedar, larch, and

juniper.

The major soil properties affecting the growth of

hardwood and coniferous trees and shrubs are depth of

the root zone, the amount of water available to plants,

and wetness.

Wetland plants are annual and perennial wild

herbaceous plants that grow on moist or wet sites.

Submerged or floating aquatic plants are excluded.

Wetland plants produce food or cover for wetland

wildlife. Examples of these plants are smartweed, wild

millet, rushes, sedges, bulrushes, wild rice, arrowhead,

waterplantain, pickerelweed, and cattail.

The major soil properties affecting wetland plants are

texture of the surface layer, wetness, acidity or

alkalinity, and slope.

Shallow water areas have an average depth of less

than 5 feet. They are useful as habitat for some wildlife

species. They are naturally wet areas or are created by

dams, levees, or water-control measures in marshes or

streams. Examples are muskrat marshes, waterfowl

feeding areas, wildlife watering developments, beaver

ponds, and other wildlife ponds.

The major soil properties affecting shallow water

areas are depth to bedrock, wetness, surface

stoniness, slope, and permeability.

Kinds of Wildlife Habitat

Habitat for openland wildlife consists of cropland,

pasture, meadows, and areas that are overgrown with

grasses, herbs, and shrubs. These areas produce grain

and seed crops, grasses and legumes, and wild

herbaceous plants. The wildlife attracted to these areas

include Hungarian partridge, pheasant, sharp-tailed

grouse, sage grouse, meadowlark, field sparrow,

killdeer, cottontail rabbit, and red fox.
196 Soil Survey Supplement of

Habitat for woodland wildlife consists of areas of

hardwoods or conifers or a mixture of these and

associated grasses, legumes, and wild herbaceous

plants. The wildlife attracted to this habitat include wild

turkey, ruffed grouse, thrushes, woodpeckers, owls, tree

squirrels, porcupine, raccoon, deer, elk, and black bear.

Habitat for wetland wildlife consists of open,

marshy or swampy shallow water areas that support

water-tolerant plants. The wildlife attracted to

this habitat include ducks, geese, herons,

bitterns, rails, kingfishers, muskrat, otter, mink,

and beaver.

Habitat for rangeland wildlife consists of areas of

shrubs and wild herbaceous plants. The wildlife

attracted to rangeland include antelope, deer, sage

grouse, meadowlark, and lark bunting.

Recreation

The soils of the survey area are rated in the tables

“Recreational Development 1” and “Recreational

Development 2” according to limitations that affect their

suitability for recreation. The ratings are both verbal and

numerical. Rating class terms indicate the extent to

which the soils are limited by all of the soil features

that affect the recreational uses.

Not limited indicates that the soil has features that

are very favorable for the specified use. Good

performance and very low maintenance can be

expected.

Somewhat limited indicates that the soil has

features that are moderately favorable for the specified

use. The limitations can be overcome or minimized by

special planning, design, or installation. Fair

performance and moderate maintenance can be

expected.

Very limited indicates that the soil has one or more

features that are unfavorable for the specified use. The

limitations generally cannot be overcome without major

soil reclamation, special design, or expensive

installation procedures. Poor performance and high

maintenance can be expected.

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

(1.00) and the point at which the soil feature is not a

limitation (0.00). The ratings in the tables are based on

restrictive soil features, such as wetness, slope, and

texture of the surface layer. Susceptibility to flooding is

considered.

Not considered in the ratings, but important in

evaluating a site, are the location and accessibility of

the area, the size and shape of the area and its scenic

quality, vegetation, access to water, potential water

impoundment sites, and access to public sewer lines.

The capacity of the soil to absorb septic tank effluent

and the ability of the soil to support vegetation also are

important. Soils that are subject to flooding are limited

for recreational uses by the duration and intensity of

flooding and the season when flooding occurs. In

planning recreational facilities, onsite assessment of

the height, duration, intensity, and frequency of flooding

is essential.

The information in the tables “Recreational

Development 1” and “Recreational Development 2” can

be supplemented by other information in this survey, for

example, interpretations for building site development,

construction materials, sanitary facilities, and water

management.

Camp areas require site preparation, such as

shaping and leveling the tent and parking areas,

stabilizing roads and intensively used areas, and

installing sanitary facilities and utility lines. Camp

areas are subject to heavy foot traffic and some

vehicular traffic. The ratings are based on the soil

properties that affect the ease of developing camp

areas and the performance of the areas after

development. Slope, stoniness, and depth to bedrock

or a cemented pan are the main concerns affecting the

development of camp areas. The soil properties that

affect the performance of the areas after development

are those that influence trafficability and promote the

growth of vegetation, especially in heavily used areas.

For good trafficability, the surface of camp areas should

absorb rainfall readily, remain firm under heavy foot

traffic, and not be dusty when dry. The soil properties

that influence trafficability are texture of the surface

layer, depth to a water table, ponding, flooding,

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Picnic areas are subject to heavy foot traffic. Most

vehicular traffic is confined to access roads and parking

areas. The ratings are based on the soil properties that

affect the ease of developing picnic areas and that

influence trafficability and the growth of vegetation after

development. Slope and stoniness are the main

concerns affecting the development of picnic areas. For

good trafficability, the surface of picnic areas should

absorb rainfall readily, remain firm under heavy foot

traffic, and not be dusty when dry. The soil properties

that influence trafficability are texture of the surface

layer, depth to a water table, ponding, flooding,

permeability, and large stones. The soil properties that
204 Soil Survey Supplement of

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Playgrounds require soils that are nearly level, are free

of stones, and can withstand intensive foot traffic. The

ratings are based on the soil properties that affect the

ease of developing playgrounds and that influence

trafficability and the growth of vegetation after

development. Slope and stoniness are the main concerns

affecting the development of playgrounds. For good

trafficability, the surface of the playgrounds should absorb

rainfall readily, remain firm under heavy foot traffic, and not

be dusty when dry. The soil properties that influence

trafficability are texture of the surface layer, depth to a

water table, ponding, flooding, permeability, and large

stones. The soil properties that affect the growth of plants

are depth to bedrock or a cemented pan, permeability,

and toxic substances in the soil.

Paths and trails for hiking and horseback riding

should require little or no slope modification through

cutting and filling. The ratings are based on the soil

properties that affect trafficability and erodibility. These

properties are stoniness, depth to a water table,

ponding, flooding, slope, and texture of the surface layer.

Off-road motorcycle trails require little or no site

preparation. They are not covered with surfacing

material or vegetation. Considerable compaction of

the soil material is likely. The ratings are based on

the soil properties that influence erodibility,

trafficability, dustiness, and the ease of revegetation.

These properties are stoniness, slope, depth to a

water table, ponding, flooding, and texture of the

surface layer.

Golf fairways are subject to heavy foot traffic and

some light vehicular traffic. Cutting or filling may be

required. Irrigation is not considered in the ratings. The

ratings are based on the soil properties that affect plant

growth and trafficability after vegetation is established.

The properties that affect plant growth are reaction;

depth to a water table; ponding; depth to bedrock or a

cemented pan; the available water capacity in the

upper 40 inches; the content of salts, sodium, or

calcium carbonate; and sulfidic materials. The

properties that affect trafficability are flooding, depth to

a water table, ponding, slope, stoniness, and the

amount of sand, clay, or organic matter in the surface

layer. The suitability of the soil for traps, tees, roughs,

and greens is not considered in the ratings.

(The information in this table indicates the dominant soil condition but does not eliminate the need for

 onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The larger the

 value, the greater the limitation. See text for further explanation of ratings in this table.)

Engineering

This section provides information for planning land

uses related to urban development and to water

management. Soils are rated for various uses, and the

most limiting features are identified. Ratings are given

for sanitary facilities, waste management, building site

development, construction materials, and water

management. The ratings are based on observed

performance of the soils and on the estimated data and

test data in the tables described in the “Soil Properties”

section.

Information in this section is intended for land use

planning, for evaluating land use alternatives, and for

planning site investigations prior to design and

construction. The information, however, has limitations.

For example, estimates and other data generally apply

only to that part of the soil within a depth of 6 feet.

Because of the map scale, small areas of different

soils may be included within the mapped areas of a

specific soil.

The information is not site specific and does not

eliminate the need for onsite investigation of the soils

or for testing and analysis by personnel experienced in

the design and construction of engineering works.

Government ordinances and regulations that restrict

certain land uses or impose specific design criteria

were not considered in preparing the information in this

section. Local ordinances and regulations should be

considered in planning, in site selection, and in design.

Soil properties, site features, and observed

performance were considered in determining the ratings

in this section. During the fieldwork for this soil survey,

determinations were made about grain-size distribution,

liquid limit, plasticity index, soil reaction, depth to

bedrock, hardness of bedrock within 5 or 6 feet of the

surface, soil wetness, depth to a seasonal high water

table, slope, likelihood of flooding, natural soil structure

aggregation, and soil density. Data were collected

about kinds of clay minerals, mineralogy of the sand

and silt fractions, and the kinds of adsorbed cations.

Estimates were made for erodibility, permeability,

corrosivity, shrink-swell potential, available water

capacity, and other behavioral characteristics affecting

engineering uses.

This information can be used to evaluate the

potential of areas for residential, commercial, industrial,

and recreational uses; make preliminary estimates of

construction conditions; evaluate alternative routes for

roads, streets, highways, pipelines, and underground

cables; evaluate alternative sites for sanitary landfills,

septic tank absorption fields, and sewage lagoons; plan

detailed onsite investigations of soils and geology;

locate potential sources of gravel, sand, earthfill, and

topsoil; plan drainage systems, irrigation systems,

ponds, terraces, and other structures for soil and water

conservation; and predict performance of proposed

small structures and pavements by comparing the

performance of existing similar structures on the same

or similar soils.

The information in the tables, along with the soil

maps, the soil descriptions, and other data provided in

this survey, can be used to make additional

interpretations.

Some of the terms used in this soil survey have a

special meaning in soil science and are defined in the

Glossary.

Sanitary Facilities

The tables “Sanitary Facilities 1” and “Sanitary

Facilities 2” show the degree and kind of soil limitations

that affect septic tank absorption fields, sewage

lagoons, sanitary landfills, and daily cover for landfill.

The ratings are both verbal and numerical. Rating class

terms indicate the extent to which the soils are limited

by all of the soil features that affect these uses.

Not limited indicates that the soil has features that

are very favorable for the specified use. Good

performance and very low maintenance can be

expected.

Somewhat limited indicates that the soil has features

that are moderately favorable for the specified use. The

limitations can be overcome or minimized by special

planning, design, or installation. Fair performance and

moderate maintenance can be expected.

Very limited indicates that the soil has one or more

features that are unfavorable for the specified use. The

limitations generally cannot be overcome without major

soil reclamation, special design, or expensive

installation procedures. Poor performance and high

maintenance can be expected.
222 Soil Survey Supplement of

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

(1.00) and the point at which the soil feature is not a

limitation (0.00).

Septic tank absorption fields are areas in which

effluent from a septic tank is distributed into the soil

through subsurface tiles or perforated pipe. Only that

part of the soil between depths of 24 and 60 inches is

evaluated. The ratings are based on the soil properties

that affect absorption of the effluent, construction and

maintenance of the system, and public health.

Permeability, depth to a water table, ponding, depth to

bedrock or a cemented pan, and flooding affect

absorption of the effluent. Stones and boulders, ice,

and bedrock or a cemented pan interfere with

installation. Subsidence interferes with installation and

maintenance. Excessive slope may cause lateral

seepage and surfacing of the effluent in downslope

areas. Some soils are underlain by loose sand and

gravel or fractured bedrock at a depth of less than 4

feet below the distribution lines. In these soils the

absorption field may not adequately filter the effluent,

particularly when the system is new. As a result, the

ground water may become contaminated.

Sewage lagoons are shallow ponds constructed to

hold sewage while aerobic bacteria decompose the

solid and liquid wastes. Lagoons should have a nearly

level floor surrounded by cut slopes or embankments of

compacted soil. Nearly impervious soil material for the

lagoon floor and sides is required to minimize seepage

and contamination of ground water. Considered in the

ratings are slope, permeability, depth to a water table,

ponding, depth to bedrock or a cemented pan, flooding,

large stones, and content of organic matter. Soil

permeability is a critical property affecting the

suitability for sewage lagoons. Most porous soils

eventually become sealed when they are used as sites

for sewage lagoons. Until sealing occurs, however, the

hazard of pollution is severe. Soils that have a

permeability rate of more than 2 inches per hour are too

porous for the proper functioning of sewage lagoons. In

these soils, seepage of the effluent can result in

contamination of the ground water. Ground-water

contamination is also a hazard if fractured bedrock is

within a depth of 40 inches, if the water table is high

enough to raise the level of sewage in the lagoon, or if

floodwater overtops the lagoon. A high content of

organic matter is detrimental to proper functioning of

the lagoon because it inhibits aerobic activity. Slope,

bedrock, and cemented pans can cause construction

problems, and large stones can hinder compaction of

the lagoon floor. If the lagoon is to be uniformly deep

throughout, the slope must be gentle enough and the

soil material must be thick enough over bedrock or a

cemented pan to make land smoothing practical.

A trench sanitary landfill is an area where solid

waste is placed in successive layers in an excavated

trench. The waste is spread, compacted, and covered

daily with a thin layer of soil excavated at the site.

When the trench is full, a final cover of soil material at

least 2 feet thick is placed over the landfill. The ratings

in the table are based on the soil properties that affect

the risk of pollution, the ease of excavation,

trafficability, and revegetation. These properties include

permeability, depth to bedrock or a cemented pan,

depth to a water table, ponding, slope, flooding,

texture, stones and boulders, highly organic layers, soil

reaction, and content of salts and sodium. Unless

otherwise stated, the ratings apply only to that part of

the soil within a depth of about 6 feet. For deeper

trenches, onsite investigation may be needed. Hard,

nonrippable bedrock, creviced bedrock, or highly

permeable strata in or directly below the proposed

trench bottom can affect the ease of excavation and the

hazard of ground-water pollution. Slope affects

construction of the trenches and the movement of

surface water around the landfill. It also affects the

construction and performance of roads in areas of the

landfill. Soil texture and consistence affect the ease

with which the trench is dug and the ease with which

the soil can be used as daily or final cover. They

determine the workability of the soil when dry and when

wet. Soils that are plastic and sticky when wet are

difficult to excavate, grade, or compact and are difficult

to place as a uniformly thick cover over a layer of

refuse. The soil material used as the final cover for a

trench landfill should be suitable for plants. It should

not have excess sodium or salts and should not be too

acid. The surface layer generally has the best

workability, the highest content of organic matter, and

the best potential for plants. Material from the surface

layer should be stockpiled for use as the final cover.

In an area sanitary landfill, solid waste is placed in

successive layers on the surface of the soil. The waste

is spread, compacted, and covered daily with a thin

layer of soil from a source away from the site. A final

cover of soil material at least 2 feet thick is placed over

the completed landfill. The ratings in the table are

based on the soil properties that affect trafficability and

the risk of pollution. These properties include flooding,

permeability, depth to a water table, ponding, slope,

and depth to bedrock or a cemented pan. Flooding is a

serious problem because it can result in pollution in

areas downstream from the landfill. If permeability is

too rapid or if fractured bedrock, a fractured cemented
Tulsa County, Oklahoma 223

pan, or the water table is close to the surface, the

leachate can contaminate the water supply. Slope is a

consideration because of the extra grading required to

maintain roads in the steeper areas of the landfill. Also,

leachate may flow along the surface of the soils in the

steeper areas and cause difficult seepage problems.

Daily cover for landfill is the soil material that is

used to cover compacted solid waste in an area

sanitary landfill. The soil material is obtained offsite,

transported to the landfill, and spread over the waste.

The ratings in the table also apply to the final cover for

a landfill. They are based on the soil properties that

affect workability, the ease of digging, and the ease of

moving and spreading the material over the refuse daily

during wet and dry periods. These properties include

soil texture, depth to a water table, ponding, rock

fragments, slope, depth to bedrock or a cemented pan,

reaction, and content of salts, sodium, or lime. Loamy

or silty soils that are free of large stones and excess

gravel are the best cover for a landfill. Clayey soils may

be sticky and difficult to spread; sandy soils are

subject to wind erosion. Slope affects the ease of

excavation and of moving the cover material. Also, it

can influence runoff, erosion, and reclamation of the

borrow area.

After soil material has been removed, the soil

material remaining in the borrow area must be thick

enough over bedrock, a cemented pan, or the water

table to permit revegetation. The soil material used as

the final cover for a landfill should be suitable for plants.

It should not have excess sodium, salts, or lime and

should not be too acid.

Agricultural Waste Management

Soil properties are important considerations in areas

where soils are used as sites for the treatment and

disposal of organic waste and wastewater. Selection of

soils with properties that favor waste management can

help to prevent environmental damage.

The tables “Agricultural Waste Management 1” and

“Agricultural Waste Management 2” show the degree

and kind of soil limitations affecting the treatment of

agricultural waste, including municipal and foodprocessing wastewater and effluent from lagoons or

storage ponds. Municipal wastewater is the waste

stream from a municipality. It contains domestic waste

and may contain industrial waste. It may have received

primary or secondary treatment. It is rarely untreated

sewage. Food-processing wastewater results from the

preparation of fruits, vegetables, milk, cheese, and

meats for public consumption. In places it is high in

content of sodium and chloride. In the context of these

tables, the effluent in lagoons and storage ponds is

from facilities used to treat or store food-processing

wastewater or domestic or animal waste. Domestic and

food-processing wastewater is very dilute, and the

effluent from the facilities that treat or store it

commonly is very low in content of carbonaceous and

nitrogenous material; the content of nitrogen commonly

ranges from 10 to 30 milligrams per liter. The

wastewater from animal waste treatment lagoons or

storage ponds, however, has much higher

concentrations of these materials, mainly because the

manure has not been diluted as much as the domestic

waste. The content of nitrogen in this wastewater

generally ranges from 50 to 2,000 milligrams per liter.

When wastewater is applied, checks should be made

to ensure that nitrogen, heavy metals, and salts are not

added in excessive amounts.

The ratings in the tables are for waste management

systems that not only dispose of and treat organic

waste or wastewater but also are beneficial to crops

(application of manure and food-processing waste,

application of sewage sludge, and disposal of

wastewater by irrigation) and for waste management

systems that are designed only for the purpose of

wastewater disposal and treatment (overland flow of

wastewater, rapid infiltration of wastewater, and slow

rate treatment of wastewater).

The ratings are both verbal and numerical. Rating

class terms indicate the extent to which the soils are

limited by all of the soil features that affect agricultural

waste management. Not limited indicates that the soil

has features that are very favorable for the specified

use. Good performance and very low maintenance can

be expected. Somewhat limited indicates that the soil

has features that are moderately favorable for the

specified use. The limitations can be overcome or

minimized by special planning, design, or installation.

Fair performance and moderate maintenance can be

expected. Very limited indicates that the soil has one

or more features that are unfavorable for the specified

use. The limitations generally cannot be overcome

without major soil reclamation, special design, or

expensive installation procedures. Poor performance

and high maintenance can be expected.

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

(1.00) and the point at which the soil feature is not a

limitation (0.00).

Application of manure and food-processing waste

not only disposes of waste material but also can

improve crop production by increasing the supply of

nutrients in the soils where the material is applied.

Manure is the excrement of livestock and poultry, and

food-processing waste is damaged fruit and vegetables

and the peelings, stems, leaves, pits, and soil particles

removed in food preparation. The manure and foodprocessing waste are either solid, slurry, or liquid. Their

nitrogen content varies. A high content of nitrogen limits

the application rate. Toxic or otherwise dangerous

wastes, such as those mixed with the lye used in food

processing, are not considered in the ratings.

The ratings are based on the soil properties that

affect absorption, plant growth, microbial activity,

erodibility, the rate at which the waste is applied, and

the method by which the waste is applied. The

properties that affect absorption include permeability,

depth to a water table, ponding, the sodium adsorption

ratio, depth to bedrock or a cemented pan, and

available water capacity. The properties that affect plant

growth and microbial activity include reaction, the

sodium adsorption ratio, salinity, and bulk density. The

wind erodibility group, the soil erodibility factor K, and

slope are considered in estimating the likelihood that

wind erosion or water erosion will transport the waste

material from the application site. Stones, cobbles, a

water table, ponding, and flooding can hinder the

application of waste. Permanently frozen soils are

unsuitable for waste treatment.

Application of sewage sludge not only disposes of

waste material but also can improve crop production by

increasing the supply of nutrients in the soils where the

material is applied. In the context of this table, sewage

sludge is the residual product of the treatment of

municipal sewage. The solid component consists

mainly of cell mass, primarily bacteria cells that
242 Soil Survey Supplement of

developed during secondary treatment and have

incorporated soluble organics into their own bodies.

The sludge has small amounts of sand, silt, and other

solid debris. The content of nitrogen varies. Some

sludge has constituents that are toxic to plants or

hazardous to the food chain, such as heavy metals and

exotic organic compounds, and should be analyzed

chemically prior to use.

The content of water in the sludge ranges from about

98 percent to less than 40 percent. The sludge is

considered liquid if it is more than about 90 percent

water, slurry if it is about 50 to 90 percent water, and

solid if it is less than about 50 percent water.

The ratings in the table are based on the soil

properties that affect absorption, plant growth, microbial

activity, erodibility, the rate at which the sludge is

applied, and the method by which the sludge is

applied. The properties that affect absorption, plant

growth, and microbial activity include permeability,

depth to a water table, ponding, the sodium adsorption

ratio, depth to bedrock or a cemented pan, available

water capacity, reaction, salinity, and bulk density. The

wind erodibility group, the soil erodibility factor K, and

slope are considered in estimating the likelihood that

wind erosion or water erosion will transport the waste

material from the application site. Stones, cobbles, a

water table, ponding, and flooding can hinder the

application of sludge. Permanently frozen soils are

unsuitable for waste treatment.

Disposal of wastewater by irrigation not only

disposes of municipal wastewater and wastewater from

food-processing plants, lagoons, and storage ponds but

also can improve crop production by increasing the

amount of water available to crops. The ratings in the

table are based on the soil properties that affect the

design, construction, management, and performance of

the irrigation system. The properties that affect design

and management include the sodium adsorption ratio,

depth to a water table, ponding, available water

capacity, permeability, slope, and flooding. The

properties that affect construction include stones,

cobbles, depth to bedrock or a cemented pan, depth to

a water table, and ponding. The properties that affect

performance include depth to bedrock or a cemented

pan, bulk density, the sodium adsorption ratio, salinity,

reaction, and the cation-exchange capacity, which is

used to estimate the capacity of a soil to adsorb heavy

metals. Permanently frozen soils are not suitable for

disposal of wastewater by irrigation.

Overland flow of wastewater is a process in which

wastewater is applied to the upper reaches of sloped

land and allowed to flow across vegetated surfaces,

sometimes called terraces, to runoff-collection ditches.

The length of the run generally is 150 to 300 feet. The

application rate ranges from 2.5 to 16.0 inches per

week. It commonly exceeds the rate needed for

irrigation of cropland. The wastewater leaves solids and

nutrients on the vegetated surfaces as it flows

downslope in a thin film. Most of the water reaches the

collection ditch, some is lost through

evapotranspiration, and a small amount may percolate

to the ground water.

The ratings in the table are based on the soil

properties that affect absorption, plant growth, microbial

activity, and the design and construction of the system.

Reaction and the cation-exchange capacity affect

absorption. Reaction, salinity, and the sodium

adsorption ratio affect plant growth and microbial

activity. Slope, permeability, depth to a water table,

ponding, flooding, depth to bedrock or a cemented pan,

stones, and cobbles affect design and construction.

Permanently frozen soils are unsuitable for waste

treatment.

Rapid infiltration of wastewater is a process in which

wastewater applied in a level basin at a rate of 4 to 120

inches per week percolates through the soil. The

wastewater may eventually reach the ground water. The

application rate commonly exceeds the rate needed for

irrigation of cropland. Vegetation is not a necessary

part of the treatment; hence, the basins may or may

not be vegetated. The thickness of the soil material

needed for proper treatment of the wastewater is more

than 72 inches. As a result, geologic and hydrologic

investigation is needed to ensure proper design and

performance and to determine the risk of ground-water

pollution.

The ratings in the table are based on the soil

properties that affect the risk of pollution and the

design, construction, and performance of the system.

Depth to a water table, ponding, flooding, and depth to

bedrock or a cemented pan affect the risk of pollution

and the design and construction of the system. Slope,

stones, and cobbles also affect design and

construction. Permeability and reaction affect

performance. Permanently frozen soils are unsuitable

for waste treatment.

Slow rate treatment of wastewater is a process in

which wastewater is applied to land at a rate normally

between 0.5 inch and 4.0 inches per week. The

application rate commonly exceeds the rate needed for

irrigation of cropland. The applied wastewater is treated

as it moves through the soil. Much of the treated water

may percolate to the ground water, and some enters

the atmosphere through evapotranspiration. The applied

water generally is not allowed to run off the surface.

Waterlogging is prevented either through control of the

application rate or through the use of tile drains, or

both.
Tulsa County, Oklahoma 243

The ratings in the table are based on the soil

properties that affect absorption, plant growth, microbial

activity, erodibility, and the application of waste. The

properties that affect absorption include the sodium

adsorption ratio, depth to a water table, ponding,

available water capacity, permeability, depth to bedrock

or a cemented pan, reaction, the cation-exchange

capacity, and slope. Reaction, the sodium adsorption

ratio, salinity, and bulk density affect plant growth

and microbial activity. The wind erodibility group,

the soil erodibility factor K, and slope are considered

in estimating the likelihood of wind erosion or water

erosion. Stones, cobbles, a water table, ponding,

and flooding can hinder the application of waste.

Permanently frozen soils are unsuitable for

waste treatment.

 onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The larger the

 value, the greater the limitation. See text for further explanation of ratings in this table.)

266 Soil Survey Supplement of

Building Site Development

Soil properties influence the development of building

sites, including the selection of the site, the design of

the structure, construction, performance after

construction, and maintenance. The tables “Building

Site Development 1” and “Building Site Development 2”

show the degree and kind of soil limitations that affect

dwellings with and without basements, small

commercial buildings, local roads and streets, shallow

excavations, and lawns and landscaping. The ratings in

the tables are both verbal and numerical. Rating class

terms indicate the extent to which the soils are limited

by all of the soil features that affect building site

development.

Not limited indicates that the soil has features that

are very favorable for the specified use. Good

performance and very low maintenance can be

expected.

Somewhat limited indicates that the soil has

features that are moderately favorable for the specified

use. The limitations can be overcome or minimized by

special planning, design, or installation. Fair

performance and moderate maintenance can be

expected.

Very limited indicates that the soil has one or more

features that are unfavorable for the specified use. The

limitations generally cannot be overcome without major

soil reclamation, special design, or expensive

installation procedures. Poor performance and high

maintenance can be expected. Numerical ratings in the

tables indicate the severity of individual limitations. The

ratings are shown as decimal fractions ranging from

0.01 to 1.00. They indicate gradations between the

point at which a soil feature has the greatest negative

impact on the use (1.00) and the point at which the soil

feature is not a limitation (0.00).

Dwellings are single-family houses of three stories or

less. For dwellings without basements, the foundation

is assumed to consist of spread footings of reinforced

concrete built on undisturbed soil at a depth of 2 feet or

at the depth of maximum frost penetration, whichever is

deeper. For dwellings with basements, the foundation is

assumed to consist of spread footings of reinforced

concrete built on undisturbed soil at a depth of about 7

feet. The ratings for dwellings are based on the soil

properties that affect the capacity of the soil to support

a load without movement and on the properties that

affect excavation and construction costs. The

properties that affect the load-supporting capacity

include depth to a water table, ponding, flooding,

subsidence, linear extensibility (shrink-swell potential),

and compressibility. Compressibility is inferred from the

Unified classification. The properties that affect the

ease and amount of excavation include depth to a

water table, ponding, flooding, slope, depth to

bedrock or a cemented pan, hardness of bedrock or a

cemented pan, and the amount and size of rock

fragments.

Small commercial buildings are structures that are

less than three stories high and do not have

basements. The foundation is assumed to consist of

spread footings of reinforced concrete built on

undisturbed soil at a depth of 2 feet or at the depth of

maximum frost penetration, whichever is deeper. The

ratings are based on the soil properties that affect the

capacity of the soil to support a load without movement

and on the properties that affect excavation and

construction costs. The properties that affect the loadsupporting capacity include depth to a water table,

ponding, flooding, subsidence, linear extensibility

(shrink-swell potential), and compressibility (which is

inferred from the Unified classification). The properties

that affect the ease and amount of excavation include

flooding, depth to a water table, ponding, slope, depth

to bedrock or a cemented pan, hardness of bedrock or

a cemented pan, and the amount and size of rock

fragments.

Local roads and streets have an all-weather surface

and carry automobile and light truck traffic all year.

They have a subgrade of cut or fill soil material; a base

of gravel, crushed rock, or soil material stabilized by

lime or cement; and a surface of flexible material

(asphalt), rigid material (concrete), or gravel with a

binder. The ratings are based on the soil properties that

affect the ease of excavation and grading and the

traffic-supporting capacity. The properties that affect the

ease of excavation and grading are depth to bedrock or

a cemented pan, hardness of bedrock or a cemented

pan, depth to a water table, ponding, flooding, the

amount of large stones, and slope. The properties that

affect the traffic-supporting capacity are soil strength

(as inferred from the AASHTO group index number),

subsidence, linear extensibility (shrink-swell potential),

the potential for frost action, depth to a water table, and

ponding.

Shallow excavations are trenches or holes dug to a

maximum depth of 5 or 6 feet for graves, utility lines,

open ditches, or other purposes. The ratings are based

on the soil properties that influence the ease of digging

and the resistance to sloughing. Depth to bedrock or a

cemented pan, hardness of bedrock or a cemented

pan, the amount of large stones, and dense layers

influence the ease of digging, filling, and compacting.

Depth to the seasonal high water table, flooding, and

ponding may restrict the period when excavations can

be made. Slope influences the ease of using

machinery. Soil texture, depth to the water table, and
Tulsa County, Oklahoma 267

linear extensibility (shrink-swell potential) influence the

resistance to sloughing.

Lawns and landscaping require soils on which turf

and ornamental trees and shrubs can be established

and maintained. Irrigation is not considered in the

ratings. The ratings are based on the soil properties

that affect plant growth and trafficability after vegetation

is established. The properties that affect plant growth

are reaction; depth to a water table; ponding; depth to

bedrock or a cemented pan; the available water

capacity in the upper 40 inches; the content of salts,

sodium, or calcium carbonate; and sulfidic materials.

The properties that affect trafficability are flooding,

depth to a water table, ponding, slope, stoniness, and

the amount of sand, clay, or organic matter in the

surface layer.

 (The information in this table indicates the dominant soil condition but does not eliminate the need

 for onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The larger the

 value, the greater the limitation. See text for further explanation of ratings in this table.)

284 Soil Survey Supplement of

Construction Materials

The tables “Construction Materials 1” and

“Construction Materials 2” give information about the

soils as potential sources of gravel, sand, topsoil,

reclamation material, and roadfill. Normal compaction,

minor processing, and other standard construction

practices are assumed.

Sand and gravel are natural aggregates suitable for

commercial use with a minimum of processing. They

are used in many kinds of construction. Specifications

for each use vary widely. In the table “Construction

Materials 1,” only the likelihood of finding material in

suitable quantity is evaluated. The suitability of the

material for specific purposes is not evaluated, nor are

factors that affect excavation of the material. The

properties used to evaluate the soil as a source of sand

or gravel are gradation of grain sizes (as indicated by

the Unified classification of the soil), the thickness of

suitable material, and the content of rock fragments. If

the bottom layer of the soil contains sand or gravel, the

soil is considered a likely source regardless of

thickness. The assumption is that the sand or gravel

layer below the depth of observation exceeds the

minimum thickness. The soils are rated good, fair, or

poor as potential sources of sand and gravel. A rating of

good or fair means that the source material is likely to

be in or below the soil. The bottom layer and the

thickest layer of the soils are assigned numerical

ratings. These ratings indicate the likelihood that the

layer is a source of sand or gravel. The number 0.00

indicates that the layer is a poor source. The number

1.00 indicates that the layer is a good source. A

number between 0.00 and 1.00 indicates the degree to

which the layer is a likely source.

The soils are rated good, fair, or poor as potential

sources reclamation material, roadfill, and topsoil. The

features that limit the soils as sources of these

materials are specified in the tables. The numerical

ratings given after the specified features indicate the

degree to which the features limit the soils as sources

of topsoil, reclamation material, or roadfill. The lower

the number, the greater the limitation.

Reclamation material is used in areas that have

been drastically disturbed by surface mining or similar

activities. When these areas are reclaimed, layers of

soil material or unconsolidated geological material, or

both, are replaced in a vertical sequence. The

reconstructed soil favors plant growth. The ratings in

the table do not apply to quarries and other mined

areas that require an offsite source of reconstruction

material. The ratings are based on the soil properties

that affect erosion and stability of the surface and the

productive potential of the reconstructed soil. These

properties include the content of sodium, salts, and

calcium carbonate; reaction; available water capacity;

erodibility; texture; content of rock fragments; and

content of organic matter and other features that affect

fertility.

Roadfill is soil material that is excavated in one

place and used in road embankments in another place.

In this table, the soils are rated as a source of roadfill

for low embankments, generally less than 6 feet high

and less exacting in design than higher embankments.

The ratings are for the whole soil, from the surface to a

depth of about 5 feet. It is assumed that soil layers will

be mixed when the soil material is excavated and

spread. The ratings are based on the amount of

suitable material and on soil properties that affect the

ease of excavation and the performance of the material

after it is in place. The thickness of the suitable

material is a major consideration. The ease of

excavation is affected by large stones, depth to a water

table, and slope. How well the soil performs in place

after it has been compacted and drained is determined

by its strength (as inferred from the AASHTO

classification of the soil) and linear extensibility (shrinkswell potential).

Topsoil is used to cover an area so that vegetation

can be established and maintained. The upper 40

inches of a soil is evaluated for use as topsoil. Also

evaluated is the reclamation potential of the borrow

area. The ratings are based on the soil properties that

affect plant growth; the ease of excavating, loading, and

spreading the material; and reclamation of the borrow

area. Toxic substances, soil reaction, and the

properties that are inferred from soil texture, such as

available water capacity and fertility, affect plant growth.

The ease of excavating, loading, and spreading is

affected by rock fragments, slope, depth to a water

table, soil texture, and thickness of suitable material.

Reclamation of the borrow area is affected by slope,

depth to a water table, rock fragments, depth to

bedrock or a cemented pan, and toxic material. The

surface layer of most soils is generally preferred for

topsoil because of its organic matter content. Organic

matter greatly increases the absorption and retention of

moisture and nutrients for plant growth.

Construction Materials 1

(The information in this table indicates the dominant soil condition but does

 not eliminate the need for onsite investigation. The ratings given for

 the thickest layer are for the thickest layer above and excluding the

 bottom layer. The numbers in the value columns range from 0.00 to 0.99.

 The greater the value, the greater the likelihood that the bottom layer

 or thickest layer of the soil is a source of sand or gravel. See text for

 further explanation of ratings in this table.)

Water Management

The tables “Water Management 1,” “Water

Management 2,” “Water Management 3,” and “Water

Management 4” give information on the soil properties

and site features that affect water management. The

degree and kind of soil limitations are given for pond

reservoir areas; embankments, dikes, and levees;

aquifer-fed excavated ponds; grassed waterways and

surface drains; terraces and diversions; tile drains and

underground outlets; and irrigation. The ratings are both

verbal and numerical. Rating class terms indicate the

extent to which the soils are limited by all of the soil

features that affect these uses.

Not limited indicates that the soil has features that

are very favorable for the specified use. Good

performance and very low maintenance can be

expected.

Somewhat limited indicates that the soil has

features that are moderately favorable for the specified

use. The limitations can be overcome or minimized by

special planning, design, or installation. Fair

performance and moderate maintenance can be

expected.

Very limited indicates that the soil has one or more

features that are unfavorable for the specified use. The

limitations generally cannot be overcome without major

soil reclamation, special design, or expensive

installation procedures. Poor performance and high

maintenance can be expected.

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

(1.00) and the point at which the soil feature is not a

limitation (0.00).

Pond reservoir areas hold water behind a dam or

embankment. Soils best suited to this use have low

seepage potential in the upper 60 inches. The seepage

potential is determined by the permeability of the soil

and the depth to fractured bedrock or other permeable

material. Excessive slope can affect the storage

capacity of the reservoir area.

Embankments, dikes, and levees are raised

structures of soil material, generally less than 20 feet

high, constructed to impound water or to protect land

against overflow. Embankments that have zoned

construction (core and shell) are not considered. In this

table, the soils are rated as a source of material for

embankment fill. The ratings apply to the soil material

below the surface layer to a depth of about 5 feet. It is

assumed that soil layers will be uniformly mixed and

compacted during construction. The ratings do not

indicate the ability of the natural soil to support an

embankment. Soil properties to a depth even greater

than the height of the embankment can affect

performance and safety of the embankment. Generally,

deeper onsite investigation is needed to determine

these properties. Soil material in embankments must

be resistant to seepage, piping, and erosion and have

favorable compaction characteristics. Unfavorable

features include less than 5 feet of suitable material

and a high content of stones or boulders, organic

matter, or salts or sodium. A high water table affects

the amount of usable material. It also affects

trafficability.

Aquifer-fed excavated ponds are pits or dugouts that

extend to a ground-water aquifer or to a depth below a

permanent water table. Excluded are ponds that are fed

only by surface runoff and embankment ponds that

impound water 3 feet or more above the original

surface. Excavated ponds are affected by depth to a

permanent water table, permeability of the aquifer, and

quality of the water as inferred from the salinity of the

soil. Depth to bedrock and the content of large stones

affect the ease of excavation.

Constructing grassed waterways and surface drains

is the construction of natural or constructed channels,

generally broad and shallow, that conduct surface water

to outlets at a nonerosive velocity. Large stones,

wetness, slope, and depth to bedrock or to a cemented

pan affect the construction of grassed waterways. A

hazard of soil blowing, low available water capacity,

restricted rooting depth, toxic substances such as

salts and sodium, and restricted permeability adversely

affect the growth and maintenance of the grass after

construction.

Constructing terraces and diversions is the

construction of embankments or a combination of

channels and ridges constructed across a slope to

control erosion and conserve moisture by intercepting

runoff. Slope, wetness, large stones, and depth to

bedrock or a cemented pan affect the construction of

terraces and diversions. A restricted rooting depth, a

severe hazard of soil blowing or water erosion, an

excessively coarse texture, and restricted permeability

adversely affect maintenance.

Tile drains and underground outlets consists of the

removal of subsurface water from the soil. How easily

and effectively the soil is drained depends on the depth

to bedrock, to a cemented pan, or to other layers that

affect the rate of water movement; permeability; depth

to a high water table; slope; susceptibility to flooding;

subsidence of organic layers; and the potential for frost

action. Excavating and grading and the stability of

ditchbanks are affected by depth to bedrock or to a

cemented pan, large stones, slope, and the hazard of
Tulsa County, Oklahoma 301

cutbanks caving. The productivity of the soil after

drainage is adversely affected by extreme acidity or by

toxic substances in the root zone, such as salts,

sodium, and sulfur. Availability of drainage outlets is not

considered in the ratings.

Irrigation is the controlled application of water to

supplement rainfall and support plant growth. The

methods that could be utilized are sprinkler, drip or

trickle, furrow, graded border, or basin or paddy

irrigation. The design and management of an irrigation

system are affected by depth to the water table, the

need for drainage, flooding, available water capacity,

intake rate, permeability, erosion hazard, and slope.

The construction of a system is affected by large

stones and depth to bedrock or to a cemented pan.

The performance of a system is affected by the depth

of the root zone, the amount of salts or sodium, and

soil reaction.

(The information in this table indicates the dominant soil condition but does not eliminate the need for

 onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The larger the

 value, the greater the limitation. See text for further explanation of ratings in this table.)

Glossary

Aeration, soil. The exchange of air in soil with air from

the atmosphere. The air in a well aerated soil is

similar to that in the atmosphere; the air in a poorly

aerated soil is considerably higher in carbon

dioxide and lower in oxygen.

Aggregate, soil. Many fine particles held in a single

mass or cluster. Natural soil aggregates, such as

granules, blocks, or prisms, are called peds. Clods

are aggregates produced by tillage or logging.

Alkali (sodic) soil. A soil having so high a degree of

alkalinity (pH 8.5 or higher) or so high a percentage

of exchangeable sodium (15 percent or more of the

total exchangeable bases), or both, that plant

growth is restricted.

Alluvium. Material, such as sand, silt, or clay,

deposited on land by streams.

Alpha,alpha-dipyridyl. A dye that when dissolved in

1N ammonium acetate is used to detect the

presence of reduced iron (Fe II) in the soil. A

positive reaction indicates a type of redoximorphic

feature.

Animal unit month (AUM). The amount of forage

required by one mature cow of approximately 1,000

pounds weight, with or without a calf, for 1 month.

Aquic conditions. Current soil wetness characterized

by saturation, reduction, and redoximorphic

features.

Argillic horizon. A subsoil horizon characterized by

an accumulation of illuvial clay.

Aspect. The direction in which a slope faces.

Association, soil. A group of soils or miscellaneous

areas geographically associated in a characteristic

repeating pattern and defined and delineated as a

single map unit.

Available water capacity (available moisture

capacity). The capacity of soils to hold water

available for use by most plants. It is commonly

defined as the difference between the amount of

soil water at field moisture capacity and the

amount at wilting point. It is commonly expressed

as inches of water per inch of soil. The capacity, in

inches, in a 60-inch profile or to a limiting layer is

expressed as:

Very low .......................................................... 0 to 3

Low .................................................................. 3 to 6

Moderate .......................................................... 6 to 9

High ................................................................ 9 to 12

Very high .............................................. more than 12

Backslope. The position that forms the steepest and

generally linear, middle portion of a hillslope. In

profile, backslopes are commonly bounded by a

convex shoulder above and a concave footslope

below.

Badland. Steep or very steep, commonly nonstony,

barren land dissected by many intermittent drainage

channels. Badland is most common in semiarid and

arid regions where streams are entrenched in soft

geologic material. Local relief generally ranges from

25 to 500 feet. Runoff potential is very high, and

geologic erosion is active.

Base saturation. The degree to which material having

cation-exchange properties is saturated with

exchangeable bases (sum of Ca, Mg, Na, and K),

expressed as a percentage of the total cationexchange capacity.

Bedding planes. Fine strata, less than 5 millimeters

thick, in unconsolidated alluvial, eolian, lacustrine,

or marine sediment.

Bedrock. The solid rock that underlies the soil and

other unconsolidated material or that is exposed at

the surface.

Bench terrace. A raised, level or nearly level strip of

earth constructed on or nearly on a contour,

supported by a barrier of rocks or similar material,

and designed to make the soil suitable for tillage

and to prevent accelerated erosion.

Blowout. A shallow depression from which all or most

of the soil material has been removed by the wind.

A blowout has a flat or irregular floor formed by a

resistant layer or by an accumulation of pebbles or

cobbles. In some blowouts the water table is

exposed.

border of an upland summit that is dissected by

ravines.

Brush management. Use of mechanical, chemical, or

biological methods to make conditions favorable for

reseeding or to reduce or eliminate competition

from woody vegetation and thus allow understory

grasses and forbs to recover. Brush management

increases forage production and thus reduces the

hazard of erosion. It can improve the habitat for

some species of wildlife.

Catena. A sequence, or “chain,” of soils on a

landscape that formed in similar kinds of parent

material but have different characteristics as a

result of differences in relief and drainage.

Cation. An ion carrying a positive charge of electricity.

The common soil cations are calcium, potassium,

magnesium, sodium, and hydrogen.

Cation-exchange capacity. The total amount of

exchangeable cations that can be held by the soil,

expressed in terms of milliequivalents per 100

grams of soil at neutrality (pH 7.0) or at some other

stated pH value. The term, as applied to soils, is

synonymous with base-exchange capacity but is

more precise in meaning.

Cemented. Material in an air-dry test specimen that

does not slake after being immersed in water for 1

hour. Cemented soil material has a brittle, hard

consistence caused by some cementing agent

other than clay. Calcium carbonate, silica, or

oxides or salts of iron and aluminum are common

cementing materials.

Channeled. Refers to a drainage area in which natural

meandering or repeated branching and

convergence of a streambed have created deeply

incised cuts, either active or abandoned, in alluvial

material.

Channery soil material. Soil material that has, by

volume, 15 to 35 percent thin, flat fragments of

sandstone, shale, slate, limestone, or schist as

much as 6 inches (15 centimeters) along the

community on a particular site. The plant cover

reproduces itself and does not change so long as

the environment remains the same.

them separately at the selected scale of mapping.

The pattern and proportion of the soils or

miscellaneous areas are somewhat similar in all

areas.

Concretions. Cemented bodies with crude internal

symmetry organized around a point, a line, or a

plane. They typically take the form of concentric

layers visible to the naked eye. Calcium carbonate,

iron oxide, and manganese oxide are common

compounds making up concretions. If formed in

place, concretions of iron oxide or manganese

oxide are generally considered a type of

redoximorphic concentration.

Conglomerate. A coarse grained, clastic rock

composed of rounded or subangular rock fragments

more than 2 millimeters in diameter. It commonly

has a matrix of sand and finer textured material.

Conglomerate is the consolidated equivalent of

combination with needed cultural and management

practices. In a good conservation cropping system,

the soil-improving crops and practices more than

offset the effects of the soil-depleting crops and

practices. Cropping systems are needed on all

tilled soils. Soil-improving practices in a

conservation cropping system include the use of

rotations that contain grasses and legumes and

the return of crop residue to the soil. Other

practices include the use of green manure crops of

grasses and legumes, proper tillage, adequate

fertilization, and weed and pest control.

Conservation tillage. A tillage system that does not

invert the soil and that leaves a protective amount

of crop residue on the surface throughout the year.

Consistence, soil. Refers to the degree of cohesion

and adhesion of soil material and its resistance to

deformation when ruptured. Consistence includes

resistance of soil material to rupture and to

of puddled soil material; and the manner in which

the soil material behaves when subject to

compression. Terms describing consistence are

defined in the “Soil Survey Manual.”

Consolidated sandstone. Sandstone that disperses

within a few hours when fragments are placed in

water. The fragments are extremely hard or very

hard when dry, are not easily crushed, and cannot

be textured by the usual field method.

Consolidated shale. Shale that disperses within a few

hours when fragments are placed in water. The

fragments are extremely hard or very hard when dry

and are not easily crushed.

Consolidated siltstone. Siltstone that disperses

within a few hours when fragments are placed in

water. The fragments are extremely hard or very

hard when dry and are not easily crushed.

Contour stripcropping. Growing crops in strips that

follow the contour. Strips of grass or close-growing

crops are alternated with strips of clean-tilled crops

or summer fallow.

Control section. The part of the soil on which

classification is based. The thickness varies

among different kinds of soil, but for many it is that

part of the soil profile between depths of 10 inches

and 40 or 80 inches.

Coppice dune. A small dune of fine grained soil

material stabilized around shrubs or small trees.

Corrosion. Soil-induced electrochemical or chemical

action that dissolves or weakens concrete or

uncoated steel.

improve and protect the soil between periods of

regular crop production, or a crop grown between

trees and vines in orchards and vineyards.

to the soil, which helps to maintain soil structure,

organic matter content, and fertility and helps to

control erosion.

side and a steep slope on the other; specifically,

an asymmetric, homoclinal ridge capped by

resistant rock layers of slight or moderate dip.

Cutbanks cave (in tables). The walls of excavations

tend to cave in or slough.

Decreasers. The most heavily grazed climax range

bedrock or to other material that restricts the

penetration of plant roots.

Deferred grazing. Postponing grazing or resting

grazing land for a prescribed period.

Dense layer (in tables). A very firm, massive layer that

has a bulk density of more than 1.8 grams per

cubic centimeter. Such a layer affects the ease of

digging and can affect filling and compacting.
342 Soil Survey Supplement of

Depth, soil. Generally, the thickness of the soil over

bedrock. Very deep soils are more than 60 inches

deep over bedrock; deep soils, 40 to 60 inches;

moderately deep, 20 to 40 inches; shallow, 10 to

20 inches; and very shallow, less than 10 inches.

Depth to rock (in tables). Bedrock is too near the

surface for the specified use.

Dip slope. A slope of the land surface, roughly

determined by and approximately conforming to the

dip of the underlying bedrock.

Diversion (or diversion terrace). A ridge of earth,

generally a terrace, built to protect downslope

areas by diverting runoff from its natural course.

Drainage class (natural). Refers to the frequency and

duration of wet periods under conditions similar to

those under which the soil formed. Alterations of

the water regime by human activities, either

through drainage or irrigation, are not a

consideration unless they have significantly

changed the morphology of the soil. Seven classes

of natural soil drainage are recognized—

excessively drained, somewhat excessively

drained, well drained, moderately well drained,

somewhat poorly drained, poorly drained, and very

poorly drained. These classes are defined in the

“Soil Survey Manual.”

Drainage, surface. Runoff, or surface flow of water,

from an area.

Drainageway. An area of ground at a lower elevation

than the surrounding ground and in which water

collects and is drained to a closed depression or

lake or to a drainageway at a lower elevation. A

incised channels at its upper reaches or throughout

its course.

Draw. A small stream valley that generally is more

open and has broader bottom land than a ravine or

gulch.

Dune. A mound, ridge, or hill of loose, windblown

granular material (generally sand), either bare or

covered with vegetation.

Eluviation. The movement of material in true solution

or colloidal suspension from one place to another

within the soil. Soil horizons that have lost material

through eluviation are eluvial; those that have

received material are illuvial.

Endosaturation. A type of saturation of the soil in

which all horizons between the upper boundary of

saturation and a depth of 2 meters are saturated.

Eolian soil material. Earthy parent material

accumulated through wind action; commonly refers

to sandy material in dunes or to loess in blankets

on the surface.

Ephemeral stream. A stream, or reach of a stream,

that flows only in direct response to precipitation. It

receives no long-continued supply from melting

snow or other source, and its channel is above the

water table at all times.

Episaturation. A type of saturation indicating a

perched water table in a soil in which saturated

layers are underlain by one or more unsaturated

layers within 2 meters of the surface.

Erosion. The wearing away of the land surface by

water, wind, ice, or other geologic agents and by

such processes as gravitational creep.

Erosion (geologic). Erosion caused by geologic

processes acting over long geologic periods and

resulting in the wearing away of mountains and the

building up of such landscape features as flood

plains and coastal plains. Synonym: natural

erosion.

Erosion (accelerated). Erosion much more rapid

than geologic erosion, mainly as a result of human

or animal activities or of a catastrophe in nature,

such as a fire, that exposes the surface.

Escarpment. A relatively continuous and steep slope

or cliff breaking the general continuity of more

gently sloping land surfaces and resulting from

erosion or faulting. Synonym: scarp.

Excess salt (in tables). Excess water-soluble salts in

the soil that restrict the growth of most plants.

Excess sodium (in tables). Excess exchangeable

sodium in the soil. The resulting poor physical

properties restrict the growth of plants.

productivity through accumulation of moisture.

Summer fallow is common in regions of limited

rainfall where cereal grain is grown. The soil is tilled

for at least one growing season for weed control

and decomposition of plant residue.

Fertility, soil. The quality that enables a soil to provide

plant nutrients, in adequate amounts and in proper

balance, for the growth of specified plants when

light, moisture, temperature, tilth, and other growth

factors are favorable.

Fibric soil material (peat). The least decomposed of

all organic soil material. Peat contains a large

amount of well preserved fiber that is readily

identifiable according to botanical origin. Peat has

the lowest bulk density and the highest water

content at saturation of all organic soil material.

Field moisture capacity. The moisture content of a

soil, expressed as a percentage of the ovendry

weight, after the gravitational, or free, water has

drained away; the field moisture content 2 or 3

days after a soaking rain; also called normal field

capacity, normal moisture capacity, or capillary

capacity.
Tulsa County, Oklahoma 343

Fine textured soil. Sandy clay, silty clay, or clay.

First bottom. The normal flood plain of a stream,

subject to frequent or occasional flooding.

stream and is subject to flooding unless protected

artificially.

Fluvial. Of or pertaining to rivers; produced by river

action, as a fluvial plain.

Footslope. The position that forms the inner, gently

inclined surface at the base of a hillslope. In profile,

microknolls in nearly level areas or of microvalleys

and microridges parallel with the slope. Typically,

the microrelief of clayey soils that shrink and swell

considerably with changes in moisture content.

Gleyed soil. Soil that formed under poor drainage,

resulting in the reduction of iron and other elements

in the profile and in gray colors.

Grassed waterway. A natural or constructed

waterway, typically broad and shallow, seeded to

grass as protection against erosion. Conducts

surface water away from cropland.

Gully. A miniature valley with steep sides cut by

running water and through which water ordinarily

runs only after rainfall. The distinction between a

gully and a rill is one of depth. A gully generally is

an obstacle to farm machinery and is too deep to

be obliterated by ordinary tillage; a rill is of lesser

depth and can be smoothed over by ordinary

tillage.

Gypsum. A mineral consisting of hydrous calcium

sulfate.

Hard bedrock. Bedrock that cannot be excavated

except by blasting or by the use of special

equipment that is not commonly used in

construction.

Hardpan. A hardened or cemented soil horizon, or

They form oxides and hydroxides that are basic.

Examples are copper, iron, cadmium, zinc,

manganese, lead, and arsenic.

Hemic soil material (mucky peat). Organic soil

material intermediate in degree of decomposition

between the less decomposed fibric material and

the more decomposed sapric material.

corn used for grain. If properly managed, residue

from these crops can be used to control erosion

until the next crop in the rotation is established.

These crops return large amounts of organic matter

to the soil.

Hill. A natural elevation of the land surface, rising as

much as 1,000 feet above surrounding lowlands,

commonly of limited summit area and having a well

defined outline; hillsides generally have slopes of

more than 15 percent. The distinction between a

hill and a mountain is arbitrary and is dependent on

local usage.

Horizon, soil. A layer of soil, approximately parallel to

the surface, having distinct characteristics

produced by soil-forming processes. In the

identification of soil horizons, an uppercase letter

represents the major horizons. Numbers or

lowercase letters that follow represent subdivisions

of the major horizons. An explanation of the

subdivisions is given in the “Soil Survey Manual.”

The major horizons of mineral soil are as follows:

O horizon.—An organic layer of fresh and decaying

plant residue.

A horizon.—The mineral horizon at or near the

surface in which an accumulation of humified

organic matter is mixed with the mineral material.

Also, a plowed surface horizon, most of which was

originally part of a B horizon.

E horizon.—The mineral horizon in which the main
344 Soil Survey Supplement of

feature is loss of silicate clay, iron, aluminum, or

some combination of these.

B horizon.—The mineral horizon below an A

horizon. The B horizon is in part a layer of

transition from the overlying A to the underlying C

horizon. The B horizon also has distinctive

characteristics, such as (1) accumulation of clay,

sesquioxides, humus, or a combination of these;

(2) prismatic or blocky structure; (3) redder or

browner colors than those in the A horizon; or (4) a

combination of these.

C horizon.—The mineral horizon or layer, excluding

indurated bedrock, that is little affected by soilforming processes and does not have the

properties typical of the overlying soil material. The

material of a C horizon may be either like or unlike

that in which the solum formed. If the material is

known to differ from that in the solum, an Arabic

numeral, commonly a 2, precedes the letter C.

Cr horizon.—Soft, consolidated bedrock beneath

the soil.

R layer.—Consolidated bedrock beneath the soil.

The bedrock commonly underlies a C horizon, but

it can be directly below an A or a B horizon.

Humus. The well decomposed, more or less stable

part of the organic matter in mineral soils.

Hydrologic soil groups. Refers to soils grouped

according to their runoff potential. The soil

properties that influence this potential are those

that affect the minimum rate of water infiltration on

a bare soil during periods after prolonged wetting

when the soil is not frozen. These properties are

depth to a seasonal high water table, the infiltration

rate and permeability after prolonged wetting, and

depth to a very slowly permeable layer. The slope

and the kind of plant cover are not considered but

are separate factors in predicting runoff.

molten or partially molten state. Major varieties

include plutonic and volcanic rock. Examples are

andesite, basalt, and granite.

roots penetrate slowly or not at all. No soil is

absolutely impervious to air and water all the time.

increase in amount as the more desirable plants

are reduced by close grazing. Increasers

commonly are the shorter plants and the less

water can infiltrate into a soil under a given set of

conditions.

Infiltration rate. The rate at which water penetrates

the surface of the soil at any given instant, usually

expressed in inches per hour. The rate can be

limited by the infiltration capacity of the soil or the

rate at which water is applied at the surface.

Intake rate. The average rate of water entering the soil

under irrigation. Most soils have a fast initial rate;

the rate decreases with application time. Therefore,

intake rate for design purposes is not a constant

but is a variable depending on the net irrigation

application. The rate of water intake, in inches per

hour, is expressed as follows:

Less than 0.2 .............................................. very low

0.2 to 0.4 ............................................................. low

0.4 to 0.75 ........................................ moderately low

0.75 to 1.25 ................................................ moderate

1.25 to 1.75 ..................................... moderately high

1.75 to 2.5 .......................................................... high

that flows for prolonged periods only when it

receives ground-water discharge or long, continued

contributions from melting snow or other surface

and shallow subsurface sources.

and grow after the climax vegetation has been

reduced by grazing. Generally, plants invade

following disturbance of the surface.

content of iron and manganese oxide because of

chemical reduction and removal, but having a clay

content similar to that of the adjacent matrix. A

type of redoximorphic depletion.

small earth ridges called border dikes, or borders.

Controlled flooding.—Water is released at intervals

from closely spaced field ditches and distributed

uniformly over the field.

Corrugation.—Water is applied to small, closely

spaced furrows or ditches in fields of close-growing

crops or in orchards so that it flows in only

one direction.

Drip (or trickle).—Water is applied slowly and

under low pressure to the surface of the soil or into

the soil through such applicators as emitters,

porous tubing, or perforated pipe.

by cultivation implements. Furrows are used for

tree and row crops.

Sprinkler.—Water is sprayed over the soil surface

through pipes or nozzles from a pressure system.

potential of soils. It is an expression of the volume

change between the water content of the clod at 1/3

or 1/10-bar tension (33kPa or 10kPa tension) and

oven dryness. Volume change is influenced by the

amount and type of clay minerals in the soil. The

volume change is the percent change for the whole

Solum. The upper part of a soil profile, above the C

horizon, in which the processes of soil formation

are active. The solum in soil consists of the A, E,

and B horizons. Generally, the characteristics of

the material in these horizons are unlike those of

the material below the solum. The living roots and

plant and animal activities are largely confined to

the solum.

Species. A single, distinct kind of plant or animal

having certain distinguishing characteristics.

Stone line. A concentration of coarse fragments in a

soil. Generally, it is indicative of an old weathered

surface. In a cross section, the line may be one

fragment or more thick. It generally overlies

material that weathered in place and is overlain by

recent sediment of variable thickness.

Stones. Rock fragments 10 to 24 inches (25 to 60

centimeters) in diameter if rounded or 15 to 24

inches (38 to 60 centimeters) in length if flat.

Stony. Refers to a soil containing stones in numbers

that interfere with or prevent tillage.

Stratified. Arranged in strata, or layers. The term

refers to geologic material. Layers in soils that

result from the processes of soil formation are

called horizons; those inherited from the parent

material are called strata.

Strath terrace. A surface cut formed by the erosion of

hard or semiconsolidated bedrock and thinly

mantled with stream deposits.

Stream channel. The hollow bed where a natural

stream or surface water flows or may flow; the

deepest or central part of the bed, formed by the

main current and covered more or less

continuously by water.

Stream terrace. One of a series of platforms in a

stream valley, flanking and more or less parallel to

the stream channel. It originally formed near the

level of the stream and is the dissected remnants

of an abandoned flood plain, streambed, or valley

floor that were produced during a former stage of

erosion or deposition.

Stripcropping. Growing crops in a systematic

arrangement of strips or bands that provide

vegetative barriers to wind erosion and water

erosion.

Structure, soil. The arrangement of primary soil

particles into compound particles or aggregates.

The principal forms of soil structure are—platy

(laminated), prismatic (vertical axis of aggregates

longer than horizontal), columnar (prisms with

rounded tops), blocky (angular or subangular), and

granular. Structureless soils are either single

grained (each grain by itself, as in dune sand) or

massive (the particles adhering without any regular

cleavage, as in many hardpans).

Stubble mulch. Stubble or other crop residue left on

the soil or partly worked into the soil. It protects

the soil from wind erosion and water erosion after

harvest, during preparation of a seedbed for the

next crop, and during the early growing period of

the new crop.

Subsoil. Technically, the B horizon; roughly, the part of

the solum below plow depth.

Subsoiling. Tilling a soil below normal plow depth,

ordinarily to shatter a hardpan or claypan.

Substratum. The part of the soil below the solum.

Subsurface layer. Any surface soil horizon (A, E, AB,

or EB) below the surface layer.

Summer fallow. The tillage of uncropped land during

the summer to control weeds and allow storage of

moisture in the soil for the growth of a later crop. A

practice common in semiarid regions, where

annual precipitation is not enough to produce a

crop every year. Summer fallow is frequently

practiced before planting winter grain.

Summit. The topographically highest position of a

hillslope. It has a nearly level (planar or only

slightly convex) surface.

Surface layer. The soil ordinarily moved in tillage, or

its equivalent in uncultivated soil, ranging in depth

from 4 to 10 inches (10 to 25 centimeters).

Frequently designated as the “plow layer,” or the

“Ap horizon.”

Surface soil. The A, E, AB, and EB horizons,

considered collectively. It includes all subdivisions

of these horizons.

Tailwater. The water directly downstream of a

structure.

Taxadjuncts. Soils that cannot be classified in a

series recognized in the classification system.

Such soils are named for a series they strongly

resemble and are designated as taxadjuncts to

that series because they differ in ways too small to

be of consequence in interpreting their use and

behavior. Soils are recognized as taxadjuncts only

when one or more of their characteristics are

slightly outside the range defined for the family of

the series for which the soils are named.

Terrace. An embankment, or ridge, constructed across

sloping soils on the contour or at a slight angle to

the contour. The terrace intercepts surface runoff

so that water soaks into the soil or flows slowly to

a prepared outlet. A terrace in a field generally is

built so that the field can be farmed. A terrace

intended mainly for drainage has a deep channel

that is maintained in permanent sod.

Terrace (geologic). An old alluvial plain, ordinarily flat

or undulating, bordering a river, a lake, or the sea.

Texture, soil. The relative proportions of sand, silt, and

clay particles in a mass of soil. The basic textural

classes, in order of increasing proportion of fine

particles, are sand, loamy sand, sandy loam, loam,

silt loam, silt, sandy clay loam, clay loam, silty clay

loam, sandy clay, silty clay, and clay. The sand,

loamy sand, and sandy loam classes may be

further divided by specifying “coarse,” “fine,” or “very

fine.”

Thin layer (in tables). Otherwise suitable soil material

that is too thin for the specified use.

Tilth, soil. The physical condition of the soil as related

to tillage, seedbed preparation, seedling

emergence, and root penetration.

Toeslope. The position that forms the gently inclined

surface at the base of a hillslope. Toeslopes in

profile are commonly gentle and linear and are

constructional surfaces forming the lower part of a

hillslope continuum that grades to valley or closeddepression floors.

Topsoil. The upper part of the soil, which is the most

favorable material for plant growth. It is ordinarily

rich in organic matter and is used to topdress

roadbanks, lawns, and land affected by mining.

Trace elements. Chemical elements, for example,

zinc, cobalt, manganese, copper, and iron, in soils

in extremely small amounts. They are essential to

plant growth.

Trafficability. The degree to which a soil is capable of

supporting vehicular traffic across a wide range in

soil moisture conditions.

Tread. The relatively flat terrace surface that was cut or

built by stream or wave action.

Upland. Land at a higher elevation, in general, than the

alluvial plain or stream terrace; land above the

lowlands along streams.

Valley. An elongated depressional area primarily

developed by stream action.

Valley fill. In glaciated regions, material deposited in

stream valleys by glacial meltwater. In nonglaciated

regions, alluvium deposited by heavily loaded

streams.

Variegation. Refers to patterns of contrasting colors

assumed to be inherited from the parent material

rather than to be the result of poor drainage.

Very deep soil. A soil that is more than 60 inches

deep over bedrock or to other material that restricts

the penetration of plant roots.

Very shallow soil. A soil that is less than 10 inches

deep over bedrock or to other material that restricts

the penetration of plant roots.

Well graded. Refers to soil material consisting of

coarse grained particles that are well distributed

over a wide range in size or diameter. Such soil

normally can be easily increased in density and

bearing properties by compaction. Contrasts with

poorly graded soil.

Wilting point (or permanent wilting point). The

moisture content of soil, on an ovendry basis, at

which a plant (specifically a sunflower) wilts so

much that it does not recover when placed in a

humid, dark chamber.
