This survey includes general information about the survey area, descriptions of the

detailed soil map units and soil series in the area, and a description of how the soils

formed. Also described is the use and management of the soils and the major soil

properties. This data may be updated as further information about soil management

becomes available.

The detailed soil map unit descriptions, when used in conjunction with the detailed

soil maps, can be useful in planning the use and management of small areas.

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 that area. Turn to the Index to Map Units in this survey, which lists the map units by

symbol and name and shows the page where each map unit is described.

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.

How To Use This Soil Survey

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 1995. Soil names and

descriptions were approved in 1996. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 1996. 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 Okfuskee 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.

This soil survey contains information that can be used in land-planning programs in

Okfuskee County. It contains predictions of soil behavior for selected land uses. The

survey also highlights limitations and hazards inherent in the soil, improvements

needed to overcome the limitations, and the impact of selected land uses on the

environment.

This soil survey is designed for many different users. Farmers, ranchers, foresters,

and agronomists can use it to evaluate the potential of the soil and the management

needed for maximum food and fiber production. Planners, community officials,

engineers, developers, builders, and home buyers can use the survey to plan land

use, select sites for construction, and identify special practices needed to ensure

proper performance. Conservationists, teachers, students, and specialists in

recreation, wildlife management, waste disposal, and pollution control can use the

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

Great differences in soil properties can occur within short distances. Some soils are

seasonally wet or subject to flooding. Some are shallow to bedrock. Some are too

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

poorly suited to use as 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. Broad areas of soils are shown on the general soil map. The location of each

soil is shown on the detailed soil maps. Each soil in the survey area is described.

Information on specific uses is given for each soil. Help in using this publication and

additional information are available at the local office of the Natural Resources

Conservation Service or the Cooperative Extension Service.

OKFUSKEE COUNTY is located in east-central Oklahoma (fig. 1). It has an area of about

402,515 acres, or 629 square miles. This soil survey updates the soil survey of

Okfuskee County, Oklahoma, published in 1952 (9). It provides additional information

and has larger maps, which show the soils in greater detail.

General Nature of the Survey Area

This section gives general information about the survey area. It describes history;

industry, transportation, and recreation; physiography and drainage; geology;

landscape evolution; and climate.

History

The area of present-day Okfuskee County was claimed by the Osage Indians at the

time of the Louisiana Purchase in 1803. It was ceded to the Creek Nation in 1826 by

the United States Government in exchange for their lands in Georgia.

A few white settlers engaged in ranching in the survey area as early as 1870, but

the land was not formally opened for settlement until after 1903. At that time, the Creek

Nation was given individual allotments and were allowed to sell all but 40 acres. This

resulted in many small farm operations.

In 1907, Okfuskee County was organized in its present size and shape. The early

settlers came principally from Texas, Arkansas, Kansas, and Missouri.

 The early agriculture of the Creek Indians consisted mainly of livestock production

and the cultivation of small patches of corn along the stream bottoms. The Indians

obtained most of their food by hunting and fishing: agriculture was only incidental.

By the early 1870’s and 1880’s, several cattle ranches were established by white

settlers. Large numbers of cattle grazed on the prairies and in forested areas. In the

early days, Okemah was surrounded with barbed-wire fencing that protected it from

ranging herds of Longhorn steers. The early ranchers grew very few crops; crops were

mainly grown for food for a rancher’s own use.

By the early 1900’s, free range became restricted and livestock production had to

be supplemented by farming. Corn, cotton, oats, grain sorghums, cowpeas, and alfalfa

were grown after the railroad provided access to outside markets. The Fort Smith and

Western Alabama Railroad served the county from 1903 to 1938. Corn and cotton

were the principal cash crops.

Today the major crop is peanuts. Grain sorghum, corn, and soybeans are grown as

minor crops. Production of bermudagrass hay, native grass hay, and alfalfa hay for onfarm use and as a cash crop is a major agribusiness in Okfuskee County.

 The population of Okfuskee County has fluctuated over time. The population was at

its highest in the late 1920’s, given as 29,016 in the 1930 census. The population

steadily declined to a low of 10,683 in 1970. In 2000, the population was 11,242.

Boley and Clearview, two of the all black towns in Oklahoma, were originally settled

after the Civil War by Freedmen from the south and/or by the Five Civilized Tribes.

These towns were incorporated by and for African Americans. Boley, a National

Historic Town, was founded in 1903 on land of the Creek Freedwoman Abigail Barnett.

In 1911, Boley had a population of 7,000 and more than 25,000 lived in the

surrounding communities. Clearview was established in the early 1900’s, and

experienced its peak in business commerce and population just before the Great

Depression.

Industry, Transportation, and Recreation

The leading industry in Okfuskee County historically has been and continues to be

agriculture and the supporting agribusiness. Today, petroleum production provides

additional income to supplement agriculture.

Okfuskee County is connected to other areas of the State by Interstate Highway 40,

two U.S. Highways, and five State Highways. The southeastern part of the county is

served by the Burlington Northern Santa Fe and the Union Pacific Railways.

Several paved farm-to-market roads extend into almost every part of the county.

The county road system consists of graded or unimproved roads. Many of the roads

on the fine-textured prairie soils are graveled and are passable during wet weather, but

some are impassable during protracted rainy spells.

Hunting and fishing have always been popular pastimes of many of the local people.

Okfuskee County has extensive areas of good to excellent wildlife habitat for dove,

quail, turkey, and deer.

Okemah Lake and the Deep Fork Wildlife Management Area are the main sources

of public recreation in the county. Some local towns have golf courses, baseball

diamonds, and parks.

Physiography and Drainage

Okfuskee County is in the Osage Plains section of the Central Lowland

Physiographic Province. There are four major land resource areas within its

Figure 1.—Location of Okfuskee County in Oklahoma.

boundaries. The far western edge of the county near the Paden area is in the Central

Rolling Red Prairies Major Land Resource Area. The remainder of the western part of

the county is in the Northern Cross Timbers Major Land Resource Area. The central

portion of the county is in the Cherokee Prairies Major Land Resource Area. The

southeastern portion of the county near the Weleetka area is in the Western Arkansas

Valley and Ridges Major Land Resource Area.

The major portion of the county is a gently rolling plain that slopes to the southeast.

There are some rough stony ridges and low hills in the southeastern part of the county.

The plain is interrupted at intervals of several miles, by east-facing escarpments that

are 50 to 100 feet high. These escarpments generally follow a southwest-northeast

course across the county and are capped by hard sandstone and underlain by shale.

These escarpments typically occupy watershed divides between drainage systems of

creeks, but in some places streams have dissected the plain above the escarpments.

In the western part of the county, the plain is more rolling and more deeply dissected.

Okfuskee County is underlain by interbedded Pennsylvanian sandstones and

shales. Many relief irregularities are the result of different rates of geologic erosion of

the two types of underlying material. The shale is subject to more rapid erosion and

occupies the broad smooth valleys between intervening ridges and escarpments,

which are protected by a cap of resistant sandstone. A few thin limestone beds occur

in places, especially in the north-central part of the county. Unconsolidated beds of

alluvial material occupy the valleys of the larger streams. Some of these are 100 feet

or more above the river and as much as 4 or 5 miles from the present river course.

These deposits are of Pleistocene age.

The highest elevation in the county, about 1,000 feet above sea level, is about 3.5

miles north of Okemah. The lowest elevation, approximately 660 feet, is where the

North Canadian River leaves the county southeast of Weleetka. The greatest localized

change in elevation occurs east of Weleetka near the county line, where hills rise

about 300 feet above the river.

The Deep Fork and North Canadian Rivers control drainage and have a gradient to

the east of about 2 and 3 feet per mile, respectively. These rivers and their tributaries

have carved broad, shallow valleys across the county. The Deep Fork River skirts the

northern boundary, and the North Canadian River crosses the southern portion of the

county and forms part of the southwestern boundary. Local drainage is controlled by

small tributaries that flow at right angles to these rivers.

Geology

Kenneth V. Luza, Oklahoma Geological Survey, helped prepare this section.

Rock units in Okfuskee County consist of Middle and Upper Pennsylvanian-age

shale and sandstone and a few thin limestone and conglomerate beds (3, 7, 8). The

outcropping rocks, which have a total thickness of about 3,850 feet, were deposited on

lowlands and in shallow seas that once covered much of eastern Oklahoma. Surficial

deposits of Quaternary age, which include flood plain deposits and high terrace sand

and gravel deposits, occur along and near the North Canadian and Deep Fork Rivers

and their major tributaries.

The oldest geologic unit exposed in Okfuskee County, the Senora Formation

(Middle Pennsylvanian in age), crops out in the southeastern corner of the county. The

Senora Formation is about 190 feet thick and consists of brown and green-brown

shale with interbedded thin, fossiliferous limestones, a few thin sandstone interbeds,

and a few coal seams. Sedimentary rocks in the Senora Formation are the parent

materials for Hector, Endsaw, and Clearview soils. Endsaw soils are deep, well

drained, and slowly permeable and formed in loamy colluvium overlying clayey

residuum weathered from shale. Hector soils are shallow, well drained, and moderately

rapidly permeable and formed in residuum weathered from sandstone. Clearview soils

are moderately deep, somewhat poorly drained, and moderately permeable and

formed in residuum weathered from sandstone with thin shale interbeds.

The Marmaton Group (Middle Pennsylvanian in age) overlies the Senora Formation

and includes, in ascending order from oldest to youngest, the Calvin Sandstone, the

Wetumka Shale, the Wewoka Formation, and the Holdenville Shale. These formations

dip generally westward and crop out along northeast-southwest trends in the eastern

third of the county. The Calvin Sandstone is a medium-grained, thin-bedded to

massive sandstone and silty shale. Total thickness is a uniform 245 feet. The Wetumka

Shale consists of 150 feet of sandy, silty, laminated shale. The Wewoka Formation is

composed of interbedded fine- to medium-grained sandstone and calcareous shale

and ranges in thickness from 730 to 780 feet. The Holdenville Shale consists of 210 to

280 feet of yellowish brown to gray-green shale with interbeds of fine-grained,

calcareous sandstone and thin limestone. Soils that developed in sedimentary rocks of

the Marmaton Group include Hector, Endsaw, Clearview, Okemah, Coweta, and Eram.

Okemah soils are very deep, somewhat poorly drained, and slowly permeable and

formed in fine textured alluvium overlying residuum weathered from shale. Coweta

soils are shallow, well drained or somewhat excessively drained, and moderately

permeable and formed in residuum weathered from sandstone with few shale

interbeds. Eram soils are moderately deep, moderately well drained, and slowly

permeable and developed primarily in residuum weathered from shale with thin

sandstone interbeds.

Sedimentary rocks in the Skiatook Group overlie the Marmaton Group and crop out

in the central part of the county. Total thickness ranges from 975 to 1,075 feet. The

Skiatook Group includes, in ascending order from oldest to youngest, the Seminole

Formation, the Checkerboard Limestone, the Coffeyville Formation, the Hogshooter

Limestone, the Nellie Bly Formation, and the Dewey Limestone. The Seminole

Formation consists of 250 to 330 feet of interbedded chert-pebble conglomerate,

shale, and fine-grained sandstone and a few thin coal seams. The Checkerboard

Limestone is a fossiliferous, crystalline limestone that ranges in thickness from 2 to 7

feet. The Coffeyville Formation consists mainly of yellowish brown and gray-green

shale with yellowish brown, fine- to medium-grained sandstone that is interbedded with

chert and limestone conglomerate. The sandstone beds are indurated and erosionresistant and form long dip slopes on cuestas. Total thickness is about 245 feet. The

Hogshooter Limestone is a massive crinoidal limestone that ranges in thickness from

1 to 6 feet. The Nellie Bly Formation is composed of 440 to 460 feet of yellowish-brown

shale and numerous fine-grained sandstone interbeds. The Dewey Limestone consists

of a lower, maximum 12-foot thick, sandy limestone or calcareous sandstone and an

upper, brownish yellow, 25- to 50-foot thick shale. The thin Checkerboard and

Hogshooter Limestones pinch out to the south and grade into shale in the central part

of the county. Soils that developed in sedimentary rocks of the Skiatook Group include

Okemah, Coweta, and Eram soils and Stephenville, Darsil, and Newalla soils near

Lake Okemah. Stephenville soils are moderately deep, well drained, and moderately

permeable and formed primarily in residuum weathered from sandstone. Darsil soils

are shallow, excessively drained, and rapidly permeable and formed in residuum

weathered from sandstone. Newalla soils are deep, moderately well drained, and very

slowly permeable and formed in sandy sediments overlying residuum weathered from

shale.

The Ochelata Group overlies the Skiakook Group, crops out in the central part of

the county, and includes, in ascending order from oldest to youngest, the Chanute,

Barnsdall, and Tallant Formations. The Chanute Formation consists of a lower, fine- to

medium-grained, 3- to 8-foot-thick sandstone and an upper, brownish yellow, 20 to 50-

foot-thick shale. The Barnsdall Formation is mostly fine-grained sandstone that is

overlain by shale. Maximum total thickness is 80 feet. The Tallant Formation consists of

basal sandstone that has a maximum thickness of 25 feet and is overlain by shale of

variable thickness. Stephenville, Darsil, and Newalla soils developed in sedimentary

rocks of the Ochelata Group.

The youngest bedrock units, the Upper Pennsylvanian Vamoosa Formation and the

Ada Group, crop out in the western part of the county and have a combined total

thickness of about 880 feet. These strata consist of a complex sequence of fine- to

very fine-grained sandstone and siltstone; red to reddish-brown shale; and

conglomerate with thin interbeds of dolomitic limestone. They were primarily deposited

in a deltaic environment. The Vamoosa Formation consists of 650 to 690 feet of thin to

massive layers of fine- to coarse-grained sandstone and sandy or silty shale. Chert

conglomerate occurs in the middle and lower parts of the formation. Soils that

developed in sedimentary rocks of the Vamossa Formation are Stephenville, Darsil,

and Newalla. The Ada Group is composed of 125 to 200 feet of orange-brown, finegrained sandstone and reddish-brown to gray shale. Soils that developed in

sedimentary rocks of the Ada Group are Grainola, Chickasha, and Renfrow. Grainola

and Renfrow soils are fine textured, moderately deep to very deep, well drained, and

very slowly permeable and developed in sediments and residuum weathered from

shale. Chickasha soils are deep, well drained, and moderately permeable and formed

in sediments and residuum weathered from sandstone.

Pleistocene high terrace deposits in Okfuskee County occur along the Deep Fork

and North Canadian Rivers and result from the entrenchment of these river valleys.

These older alluvial sediments are topographically higher and generally adjacent to

modern flood plains. Stream terrace deposits are composed of lenticular beds of sand,

silt, clay, and gravel. Total thickness ranges from a few feet to about 100 feet. Glentosh,

Larton, and Karma soils developed in alluvium on Pleistocene stream terraces.

Glentosh soils are very deep, excessively drained, and rapidly permeable and formed

in sandy alluvium reworked by wind. Larton soils are very deep, well drained, and

moderately permeable. They also developed in sandy alluvium reworked by wind and

are often associated with Glentosh soils. Karma soils are very deep, well drained, and

moderately permeable and formed in loamy alluvium.

Holocene alluvium in Okfuskee County occurs on flood plains of the Deep Fork and

North Canadian Rivers and their tributaries and is composed of sand, silt, clay, and

lenticular beds of gravel. Thickness ranges from about 30 to 100 feet and averages

about 50 feet along the Deep Fork and North Canadian Rivers. Along minor streams,

thickness ranges from a few feet to about 50 feet and averages about 25 feet. Grady,

Severn, and Yahola soils formed in Holocene alluvium. Grady soils are very deep,

poorly drained, and slowly permeable and formed in fine textured alluvium. Severn and

Yahola soils are very deep, well drained, and moderately rapidly permeable and

formed in silty or loamy alluvium.

The regional structure of Okfuskee County is characterized as a gently dipping

homocline in which the strata generally strike north to northeast with a westward dip of

0.5 to 1 degree. Surface faults within the county typically produce an en echelon

pattern and occur in belts that trend northwest to southeast. All of these faults appear

to show normal displacement. Fault displacements are generally less than 40 feet at

the surface and decrease downward. However, several faults extend into deeper,

subsurface strata. Twenty-three earthquakes are known to have occurred in Okfuskee

County from 1882 to 2000 (6). Two earthquakes with surface sensation were recorded

in the county on May 2, 1969, and March 3, 1984. Both earthquakes were centered

about 12 kilometers north of Okemah and produced no damage, and the affected

areas were probably restricted to a few tens of square kilometers from the epicenter.

The remaining earthquakes were instrumentally located and are not known to have

surface expression. Small movements of only several millimeters on some of the deep,

subsurface faults may be responsible for these earthquakes.

Good-quality ground water is abundant in some of the major Quaternary alluvium

and terrace deposits along stream beds and also in the Vamoosa-Ada aquifer. The

aquifer, about 850 feet thick, yields 25 to 150 gallons per minute of water containing

200 to 400 milligrams per liter of total dissolved solids (3, 4, 7). The aquifer is

recharged by precipitation and runoff that infiltrate and percolate down through the soil

into the porous and permeable sandstone beds of the Vamoosa Formation and the

Ada Group.

Oil and gas are the most important mineral resources in the county. Oil has been

found in every township of Okfuskee County (8). The principal non-metallic mineral

resources are sand and gravel, which are mined from alluvium associated with the

North Canadian and Deep Fork Rivers and their major tributaries. Gravel pits are at

many locations along the outcrop of the Vamoosa Formation. At least three volcanic

ash deposits occur in Okfuskee County (8). The deposits are generally small (less

than 100 acres in size), are less than 10 feet thick, and are associated with stream

terrace deposits. No record of coal production officially exists for Okfuskee County (5).

However, abandoned mine shafts are in Sections 15 and 28, Township 10 N.,

Range 12 E.

Landscape Evolution

The evolution of the landscape is not static. What we see today is only a brief

moment of geologic time. The landscape changes are the product of years of uplift and

erosion. Years of erosion and deposition by water and wind change the surface of the

land. Over the last million years, many climatic changes associated with ice ages and

periods of warming have produced intense periods of erosion and deposition. These

periods were interspersed with long periods of stability. The two rivers which cross

Okfuskee County have sculpted the landscape, eroding valleys and depositing

sediments. Wind later reworked some of the sandier sediments. These processes

combined with geologic uplifts and different rates of geologic erosion have produced

the landscape of present-day Okfuskee County.

Climate

The table “Temperature and Precipitation” gives data on temperature and

precipitation for the survey area as recorded at Okemah, Oklahoma, in the period

1961 to 1990. 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 the length of the growing season.

In winter, the average temperature is 40 degrees F and the average daily minimum

temperature is 30 degrees. The lowest temperature on record, which occurred at

Okemah on January 18, 1930 is -10 degrees. In summer, the average temperature is

80 degrees and the average daily maximum temperature is 91 degrees. The highest

temperature, which occurred at Okemah on August 10, 1936, is 115 degrees.

Growing degree days are shown in the table “Temperature and Precipitation”. They

are equivalent to “heat units.” During the month, growing degree days accumulate by

the amount that the average temperature each day exceeds a base temperature (40

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.

The total annual precipitation is about 38.76 inches. Of this, 23.46 inches, or about

61 percent, usually falls in April through September. The growing season for most

crops falls within this period. The heaviest one-day rainfall during the period of record

was 10.05 inches, recorded at Okemah on April 14, 1945. Thunderstorms occur on

about 51 days each year, and most occur in May.

The average seasonal snowfall is 6.6 inches. The greatest snow depth at any one

time during the period of record was 15 inches. On an average, 3 days per year have

at least 1 inch of snow on the ground. The heaviest one-day snowfall on record was

10.5 inches.

The average relative humidity in mid-afternoon is about 53 percent. Humidity is

higher at night, and the average at dawn is about 71 percent. The sun shines 78

percent of the time in summer and 54 percent in winter. The prevailing wind is from the

south-southeast. Average windspeed is highest, 12.2 miles per hour, in March.

How This Survey Was Made

This survey was made to provide information about the soils and miscellaneous

areas in the survey area. The information includes a description of the soils and

miscellaneous areas and their location and a discussion of their suitability, limitations,

and management for specified uses. Soil scientists observed the steepness, length,

and shape of the slopes; the general pattern of drainage; the kinds of crops and native

plants; and the kinds of bedrock. They dug many holes to study the soil profile, which

is the sequence of natural layers, or horizons, in a soil. The profile extends from the

surface down into the unconsolidated material in which the soil formed. The

unconsolidated material is devoid of roots and other living organisms and has not

been changed by other biological activity.

The soils and miscellaneous areas in the survey area are in an orderly pattern that

is related to the geology, landforms, relief, climate, and natural vegetation of the area.

Each kind of soil and miscellaneous area is associated with a particular kind or

segment of the landscape. By observing the soils and miscellaneous areas in the

survey area and relating their position to specific segments of the landscape, soil

scientists develop a concept, or model, of how the soils were formed. Thus, during

mapping, this model enables the soil scientists to predict with a considerable degree of

accuracy the kind of soil or miscellaneous area at a specific location on the landscape.

Individual soils on the landscape commonly merge into one another as their

characteristics gradually change. To construct an accurate map, however, soil

scientists must determine the boundaries between the soils. They can observe only a

limited number of soil profiles. Nevertheless, these observations, supplemented by an

understanding of the soil-vegetation-landscape relationship, are sufficient to verify

predictions of the kinds of soil in an area and to determine the boundaries.

Soil scientists recorded the characteristics of the soil profiles that they studied. They

noted color, texture, size, and shape of soil aggregates, kind and amount of rock

fragments, distribution of plant roots, reaction, and other features that enable them to

identify soils. After describing the soils in the survey area and determining their

properties, the soil scientists assigned the soils to taxonomic classes (units).

Taxonomic classes are concepts. Each taxonomic class has a set of soil

characteristics with precisely defined limits. The classes are used as a basis for

comparison to classify soils systematically. Soil taxonomy, the system of taxonomic

classification used in the United States, is based mainly on the kind and character of

soil properties and the arrangement of horizons within the profile. After the soil

scientists classified and named the soils in the survey area, they compared the

individual soils with similar soils in the same taxonomic class in other areas so that

they could confirm data and assemble additional data based on experience and

research.

While a soil survey is in progress, samples of some of the soils in the area generally

are collected for laboratory analyses and for engineering tests. Soil scientists interpret

the data from these analyses and tests as well as the field-observed characteristics

and the soil properties to determine the expected behavior of the soils under different

uses. Interpretations for all of the soils are field tested through observation of the soils

in different uses and under different levels of management. Some interpretations are

modified to fit local conditions, and some new interpretations are developed to meet

local needs. Data are assembled from other sources, such as research information,

production records, and field experience of specialists. For example, data on crop

yields under defined levels of management are assembled from farm records and from

field or plot experiments on the same kinds of soil.

Predictions about soil behavior are based not only on soil properties but also on

such variables as climate and biological activity. Soil conditions are predictable over

long periods of time, but they are not predictable from year to year. For example, soil
Soil Survey of Okfuskee County, Oklahoma

11

scientists can predict with a fairly high degree of accuracy that a given soil will have a

high water table within certain depths in most years, but they cannot predict that a high

water table will always be at a specific level in the soil on a specific date.

After soil scientists located and identified the significant natural bodies of soil in the

survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings, fields,

roads, and rivers, all of which help in locating boundaries accurately.

The descriptions, names, and delineations of the soils in this survey area do not

fully agree with those of the soils in adjacent survey areas. Differences are the result

of a better knowledge of soils, modifications in series concepts, or variations in the

intensity of mapping or in the extent of the soils in the survey areas.

13

This section relates the soils in the survey area to the major factors of soil

formation.

Factors of Soil Formation

Soil is produced by the action of soil-forming processes on materials deposited or

accumulated by geologic agents. The characteristics of the soil at any given point are

determined by the physical and mineralogical composition of the parent material; the

climate under which the soil material has accumulated and existed since

accumulation; living organisms on and in the soil; topography, or relief; and the length

of time that the forces of soil development have acted on the soil material.

Parent Material

Parent material influences the chemical, physical, mineral composition, and color of

the soil. Whether the parent material is unconsolidated or consolidated and the degree

of consolidation influence the rate of soil formation.

Soils on the uplands in Okfuskee County formed in materials weathered from

sandstone, shale, and thin strata of limestone. Soils that formed in the western and

central parts of the county, on gently rolling plains, include Bates, Dennis, and

Stephenville soils. Soils that formed in the southeastern part of the county, on stony

ridges and low hills, include Hector and Clearview soils.

Alluvial sediments are extensive along steams and rivers in the county. The kind of

sediments deposited and the kinds of soil that formed in the sediments depend largely

on the source of the sediment and the velocity of the streams. Soils that formed in

ancient fluvial sediments include Konawa and Stidham soils. Soils that formed in

recent fluvial sediments include Roebuck and Yahola soils.

Climate

Okfuskee County has a subtropical humid climate. Because the climate is fairly

uniform throughout the county, the differences between soils cannot be attributed to

differences in climate based on the present climatic regime. The amount of moisture

and warm temperatures have been sufficient to promote the formation of distinct layers

in many of the soils. Soil leaching is moderate because the generous amount of

precipitation is well distributed. The summers are excellent for rapid and luxuriant plant

growth.

Living Organisms

Plants, burrowing animals, insects, and soil micro-organisms have a direct influence

on the formation of soils. The native grasses and trees in the county have different

effects on the losses and gains of organic matter and plant nutrients and on the soil

structure and porosity. Soils that formed under prairie vegetation, such as Okemah

Formation of the Soils
Soil Survey of Okfuskee County, Oklahoma

14

and Bates soils, have a very dark brown surface layer and a moderately high content

of organic matter. Soils that formed under trees, such as Niotaze soils, have a grayish

brown or brown surface layer and a low content of organic matter.

Topography

Relief influences the formation of the soils mainly through its effect on the

movement of water, erosion, soil temperature, and the kind of plant cover. In Okfuskee

County, the resistance of underlying formations to weathering and geological erosion

determines relief. The topography of the western and central parts of Okfuskee County

is a gently rolling plain that slopes to the southeast. The soils in these areas are deep

or moderately deep and are more developed. The stony ridges and low hills of the

southeastern part of the county are more dissected and have more runoff and erosion.

The soils in these areas are residual, are moderately deep to shallow, and are less

developed.

Time

As a factor in soil formation, time is difficult to measure strictly in years. The length

of time needed for development of genetic horizons depends on the intensity and the

interactions of the soil-forming factors in promoting the losses, gains, transfers, or

transformations of the constituents necessary in the formation of soil horizons. Soils

that have no definite genetic horizons are young or immature. Mature or older soils

have approached equilibrium with their environment and tend to have well defined

horizons.

Soils in Okfuskee County range from young to very old. Dennis and Okemah soils

are examples of old soils. Stephenville and Bates soils are younger soils, but they have

well expressed horizons. Darsil and Hector soils are considered young soils because

they have had sufficient time to develop well expressed horizons. Because they are

sloping, however, geological erosion has taken away soil material almost as fast as it

forms. Yahola and Gaddy soils are young soils that formed in recent sediments on

flood plains and show little horizon development.
15

The system of soil classification used by the National Cooperative Soil Survey has

six categories (11, 14). Beginning with the broadest, these categories are the order,

suborder, great group, subgroup, family, and series. Classification is based on soil

properties observed in the field or inferred from those observations or from laboratory

measurements. The table “Classification of the Soils” shows the classification of each

of the soils in the survey area. The categories are defined in the following paragraphs.

ORDER. Twelve soil orders are recognized. The differences among orders reflect

the dominant soil-forming processes and the degree of soil formation. Each order is

identified by a word ending in sol. An example is Mollisol.

SUBORDER. Each order is divided into suborders primarily on the basis of

properties that influence soil genesis and are important to plant growth or properties

that 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 humid, 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 development of pedogenic horizons;

soil moisture and temperature regimes; and base status. Each great group is identified

by the name of a suborder and by a prefix that indicates a property of the soil. An

example is Argiudolls (Argi, meaning argillic horizonation, plus udoll, the suborder of

the Mollisols that has an udic moisture regime).

SUBGROUP. Each great group has a typic subgroup. Other subgroups are

intergrades or extragrades. The typic is the central concept of the great group; it is not

necessarily the most extensive. Intergrades are transitions to other orders, suborders,

or great groups. Extragrades have some properties that are not representative of the

great group, 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 Aquic Argiudolls.

FAMILY. Families are established within a subgroup on the basis of physical and

chemical properties and other characteristics that affect management. Generally, the

properties are those of horizons below plow depth where there is much biological

activity. Among the properties and characteristics considered are: particle-size class,

mineral content, temperature regime, thickness of the root zone, consistence, moisture

equivalent, slope, and permanent cracks. A family name consists of the name of a

subgroup preceded by terms that indicate soil properties. An example is fine, mixed,

thermic Aquic Argiudolls.

SERIES. The series consists of soils that have similar horizons in their profile. The

horizons are similar in color, texture, structure, reaction, consistence, mineral and

chemical composition, and arrangement in the profile. The texture of the surface layer

or of the substratum can differ within a series.

Descriptions of the soils are available in the “Official Series Descriptions,” which are

online at http://soils.usda.gov. Characteristics of the soil and the material in which it

formed are identified for each soil series. A pedon, a small three-dimensional area of

soil, which is typical of the series is described. The detailed description of each soil

horizon follows standards in the “Soil Survey Manual” (13). Many of the technical terms

used in the descriptions are defined in “Soil Taxonomy” (11).

The map units on the detailed soil maps in this survey represent the soils or

miscellaneous areas in the survey area. The map unit descriptions in this section,

along with the maps, can be used to determine the suitability and potential of a unit for

specific uses. They also can be used to plan the management needed for those uses.

More information about each map unit is given in the section “Use and Management of

the Soils.”

A map unit delineation on the detailed soil maps represents an area on the

landscape and consists of one or more soils or miscellaneous areas. A map unit is

identified and named according to the taxonomic classification of the dominant soils or

miscellaneous areas. Within a taxonomic class there are precisely defined limits for the

properties of the soils. On the landscape, however, the soils and miscellaneous areas

are natural phenomena, and they have the characteristic variability of all natural

phenomena. Thus, the range of some observed properties may extend beyond the

limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if

ever, are mapped without areas of minor components of other taxonomic classes.

Consequently, map units are made up of the soils or miscellaneous areas for which

they are named and some areas of included soils that belong to other taxonomic

classes.

Most included soils have properties similar to those of the dominant soil or soils in

the map unit, and thus they do not affect use and management. These are called

noncontrasting or similar inclusions. They may or may not be mentioned in the map

unit description. Other included soils and miscellaneous areas, however, have

properties and behavioral characteristics divergent enough to affect use or to require

different management. These are called contrasting, or dissimilar, inclusions. They

generally are in small areas and could not be mapped separately because of the scale

used. Descriptions of the soils are available in the “Official Series Descriptions,” which

are online at http://soils.usda.gov. Some small areas of strongly contrasting soils or

miscellaneous areas are identified by a special symbol on the maps. The included

areas of contrasting soils or miscellaneous areas are mentioned in the map unit

descriptions. A few included areas may not have been observed and consequently

they are not mentioned in the descriptions, especially where the pattern was so

complex that it was impractical to make enough observations to identify all the soils

and miscellaneous areas on the landscape.

The presence of included areas in a map unit in no way diminishes the usefulness

or accuracy of the data. The objective of mapping is not to delineate pure taxonomic

classes but rather to separate the landscape into segments that have similar use and

management requirements. The delineation of such landscape segments on the map

provides sufficient information for the development of resource plans, but if intensive

use of small areas is planned, onsite investigation is needed to define and locate the

soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions.

Each description includes general facts about the unit and gives the principal hazards

and limitations to be considered in planning for specific uses.

Soils that have profiles that are almost alike make up a soil series. Except for

differences in texture of the surface layer or of the underlying layers, all the soils of a

series have major horizons that are similar in composition, thickness, and

arrangement.

Soils of one series can differ in texture of the surface layer or of the underlying

layers. They also can differ in slope, stoniness, salinity, wetness, degree of erosion,

and other characteristics that affect their use. On the basis of such differences, a soil

series is divided into soil phases. Most of the areas shown on the detailed soil maps

are phases of soil series. 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 a

phase of the Dennis series.

Some map units are made up of two or more major soils or miscellaneous areas.

These map units are complexes or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricate

pattern or in such small areas that they cannot be shown separately on the maps. The

pattern and proportion of the soils or miscellaneous areas are somewhat similar in all

areas. Endsaw-Hector complex, 5 to 12 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas

that could be mapped individually but are mapped as one unit because similar

interpretations can be made for use and management. The pattern and proportion of

the soils or miscellaneous areas in a mapped area are not uniform. An area can be

made up of only one of the major soils or miscellaneous areas, or it can be made up of

all of them. Glentosh and Larton soils, 0 to 3 percent slopes, is an undifferentiated

group in this survey area.

This survey includes miscellaneous areas. Such areas have little or no soil material

and support little or no vegetation. The Gullied land part of Konawa-Gullied land

complex, 3 to 12 percent slopes, is an example. Miscellaneous areas are shown on

the soil maps. Areas that are too small to be to be shown are identified by a special

symbol on the soil maps.

The table “Acreage and Proportionate Extent of the Soils,” located at the end of this

section, gives the acreage and proportionate extent of each map unit. Other tables

(see “Summary of Tables”) give properties of the soils and the limitations, capabilities,

and potentials for many uses. The Glossary defines many of the terms used in

describing the soils or miscellaneous areas.

This soil survey is an inventory and evaluation of the soils in the survey area. It can

be used to adjust land uses to the limitations and potentials of natural resources and

the environment. Also, it can help to prevent soil-related failures in land uses.

In preparing a soil survey, soil scientists, conservationists, engineers, and others

collect extensive field data about the nature and behavioral characteristics of the soils.

They collect data on erosion, droughtiness, flooding, and other factors that affect

various soil uses and management. Field experience and collected data on soil

properties and performance are used as a basis in predicting soil behavior.

Information in this section can be used to plan the use and management of soils for

crops and pasture; as rangeland and woodland; as sites for buildings, sanitary

facilities, highways and other transportation systems, and parks and other recreational

facilities; and for wildlife habitat. It can be used to identify the potentials and limitations

of each soil for specific land uses and to help prevent construction failures caused by

unfavorable soil properties.

Interpretive ratings help engineers, planners, and others understand how soil

properties influence important nonagricultural uses, such as building site development

and construction materials. The ratings indicate the most restrictive soil features

affecting the suitability of the soils for these uses.

Soils are rated in their natural state. No unusual modification of the soil site or

material is made other than that which is considered normal practice for the rated use.

Even though soils may have limitations, it is important to remember that engineers and

others can modify soil features or can design or adjust the plans for a structure to

compensate for most of the limitations. Most of these practices, however, are costly.

The final decision in selecting a site for a particular use generally involves weighing

the costs of site preparation and maintenance.

Planners and others using soil survey information can evaluate the effect of specific

land uses on productivity and on the environment in all or part of the survey area. The

survey can help planners to maintain or create a land use pattern in harmony with the

natural soil.

Contractors can use this survey to locate sources of sand and gravel, roadfill, and

topsoil. They can use it to identify areas where bedrock, wetness, or very firm soil

layers can cause difficulty in excavation.

Health officials, highway officials, engineers, and others may also find this survey

useful. The survey can help them plan the safe disposal of wastes and locate sites for

pavements, sidewalks, campgrounds, playgrounds, lawns, and trees and shrubs.

The classification and extent of the soils in this survey area are shown in the

tables “Classification of the Soils” and “Acreage and Proportionate Extent of the

Soils.”

Resources Conservation Service is explained, and the estimated yields of the main

crops and hay and pasture plants are listed for each soil.

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, soils generally are grouped at three levels: capability class,

subclass, and unit (10). 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 the 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 and Pasture.”

Land Capability and Yields per Acre of Crops and 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)

Estimated Yields of Crops, Hay, and Pasture

The average yields per acre that can be expected of the principal crops under a

high level of management are shown in the table “Land Capability and Yields per Acre

of Crops and 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.

For yields of irrigated crops, it is assumed that the irrigation system is adapted to

the soils and to the crops grown, that good-quality irrigation water is uniformly applied

as needed, and that tillage is kept to a minimum.

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 8, in the “Range” section. 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 Crops and Pasture.”

Prime Farmland

Prime farmland is of major importance in meeting the Nation’s short- and longrange 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
Soil Survey of Okfuskee County, Oklahoma

130

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 (12).

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 are not 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 water-control

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 82,000 acres, or more than 20 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.” On some

soils included in the table, measures that overcome limitations are needed. The

location of each map unit is shown on the detailed soil maps. The soil qualities that

affect use and management are described in the section “Detailed Soil Map Units.”

This list does not constitute a recommendation for a particular land use.

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 table “Agricultural Waste Management, Parts I and II,” shows the degree and

kind of soil limitations affecting the treatment of agricultural waste, including municipal

and food-processing 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 this table, the

effluent in lagoons and storage ponds is from facilities used to treat or store foodprocessing 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 table 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 table 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

food-processing 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.
Soil Survey of Okfuskee County, Oklahoma

133

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 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.
Soil Survey of Okfuskee County, Oklahoma

134

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 effect plant growth and microbial activity. Slope, permeabitity, 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 propert 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.

Permently 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 throught the soil. Most 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.

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.

Range

Mark Moseley, Range Conservationist, Natural Resources Conservation Service, helped prepare this

section.

Range, grazed forestland, 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,

savannahs, 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 forestland 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 forestland and forestland that has been cleared and is

managed for native or naturalized forage plants.

Rangeland makes up about 37 percent of the land in Okfuskee County and is

located mainly in the western and central parts of the county. There has been a recent

trend to reseed some areas of abandoned cropland with a mixture of native grass

species or to allow them to naturally reseed to native species. The range is used

primarily for grazing by domestic cattle or to produce native hay; however, its

importance as wildlife habitat is becoming increasingly important as more landowners

choose to lease the hunting rights on their range for an additional source of income.

The range in Okfuskee County originally produced a wide variety of tall grasses and

some mid grasses interspersed with an abundance of forbs. The plant communities,

however, have changed drastically during the past 130 years. Heavy overgrazing has

deteriorated some of the grassland, and the extent of high-quality vegetation has been

severely reduced. Many areas are now dominated by poor-quality grasses, and there

is a significant increase in the extent of poor-quality forbs and woody shrubs. Eastern

red cedar, winged elm, common persimmon, blackjack oak, and post oak have also

encroached as a result of the lack of prairie fires since humans have settled the area.

However, many small remnant areas of the original plant species still occur where

protected. Good grazing management can help to re-establish these areas to highquality plants.

Okfuskee County has four types of range. The first type is in the far western part of

the county around the Paden area, west to the county line, and along the North

Canadian River flood plain. The soils of this area are sandy to clayey and shallow to

deep to bedrock or alluvial sediments. This area is typified by a rolling plain that is

deeply dissected. These soils support a mixture of mostly tall and some mid grasses,

and the potential productivity is moderate.

The second type is in the western part of the county and on the terraces of the

North Canadian River. The soils of this area are sandy to clayey and shallow to very

deep to bedrock or alluvial sediments. This area is typified by a gently rolling plain that

is dissected. These soils support tall grasses, and the potential productivity is

moderate.

The third type is in the central part of the county on terraces of the North Canadian

River and on the flood plain and terraces of the Deep Fork of the Canadian River. The

soils of this area are loamy to clayey and moderately deep to very deep to bedrock or

alluvial sediments. This area is typified by a gently rolling plain with some rough stony

ridges and low hills. These soils support tall grasses, and the potential productivity is

high.

The fourth type is in the southeast and east-central part of the county and on

terraces of the North Canadian River. The soils of this area are loamy to clayey. They

are mainly shallow to moderately deep but are very deep to bedrock in some places.

This area is typified by a gently rolling plain with rough stony ridges and low hills and

has the largest amount of relief in the county. These soils support tall grasses, and the

potential productivity is low to high.

Approximately 75 percent of the annual production of forage occurs in April through

July, following spring and early summer rains. A second smaller growth period occurs

in the fall when sufficient moisture is available.

The table “Rangeland Productivity and Characteristic Plant Communities” 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. Explanation of the column headings in this table follows.

An ecological site 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.

Many different ecological sites are in the survey area. 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 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

the local office 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 8 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 is the comparison from 1 to 100 percent of the present plant

community to a vegetative state on an ecological site. The Natural Resources

Conservation Service uses similarity index two ways.

The first way uses the similarity index to compare the present vegetation on an

ecological site to the presumed historic vegetation for that site. This comparison

provides the client a basis for learning the extent and direction of changes that have

taken place between current vegetation and historic vegetation.

A similarity index of 70 would suggest that the present plant community contains 70

percent of the presumed historic plant community for that site.

The second way uses the similarity index as a measure of how near the current

plant community is to the landowner’s goal for the land. The management goal for

rangeland is not necessarily a similarity index of 100 as compared to the historic plant

community. The similarity index can thus 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 plowing. Grazing animals select

the most palatable plants. These plants will eventually die out if they are continually

grazed. A very severe disturbance can completely destroy the natural community.

Under these conditions, the less desirable plants, such as annuals and weedlike

plants, can increase in abundance. If the plant community and the soils have not

deteriorated significantly, the community 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 establish management objectives,

planned grazing systems, stocking rates, suitable wildlife management practices,

potential for recreational uses, and condition of watersheds.

Rangeland Management

Rangeland 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 the range

trend. These changes takes 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.

The primary range management practices used in Okfuskee 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 allowing 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.
Soil Survey of Okfuskee County, Oklahoma

199

4. Rest periods during which grazed plants are given enough rest to recover and

to maintain growth.

It is important to remember that forage production is controlled by rainfall while

composition is determined by grazing management.

Setting stocking rates is not an exact science because there are influences from

grazing management systems, season of use, mix of livestock, and seasonal forage

production. Some basic rules, 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 in excellent condition for

an average season is 3,500 pounds of air-dry grasses, forbs, and woody species.

Twenty five percent of this is 875 pounds.

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

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 9,490 pounds). Dividing the 875 pounds of

usable forage per acre into the 9,490 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 at the local office of

the Natural Resources Conservation Service.

Ecological Sites

Thirty-one ecological sites are recognized in Okfuskee County. The ecological site

identifier has eleven characters. The “R” indicates an ecological site. The next four

characters identify the major land resource area, the sixth 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. The ecological

site identifier is followed by the proper name for the ecological site. The following

paragraphs describe the ecological sites in Okfuskee County and list the plants that

are characteristic of each site. Detailed ecological site descriptions are available at the

local office of the Natural Resources Conservation Service.

R118BY875OK, Eroded Sandy Savannah Pe 66-72.—This site is in areas where

part or all or part of the A horizon has been removed by erosion. The soil’s integrity

has been changed. Because of the past erosion and the probability of ongoing

erosion, the plant community can be determined only by onsite inspection. The

productivity of this site has not been determined. Refer to “R118BY075OK, Sandy

Savannah Pe 66-72” for the historic climax vegetation on the parent site.

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 at the local

office of the Natural Resources Conservation Service or the Cooperative Extension

Service or from a nursery.

Recreation

The soils of the survey area are rated in the table “Recreational Development, Parts

I and II,” 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 table 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 table 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 this table 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 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

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, building site

development, construction materials, and water management. The ratings are based

on observed performance of the soils and on the data in the tables described under

the heading “Soil Properties.”

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 between the surface and a depth of 5 to 7 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 particle-size distribution, liquid limit, plasticity index,

soil reaction, depth to bedrock, hardness of bedrock within 5 to 7 feet of the surface,

soil wetness, depth to a water table, ponding, 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

Sanitary Facilities

The table “Sanitary Facilities, Parts I and II,” shows 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.

Numerical ratings in the table 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 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.

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 table “Building Site Development, Parts I and II,” shows 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 table 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 table 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 load-supporting 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
Soil Survey of Okfuskee County, Oklahoma

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 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)

Construction Materials

The table “Construction Materials, Parts I and II,” gives 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, 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 of topsoil, reclamation

material, and roadfill. The features that limit the soils as sources of these materials are

specified in the table. 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

(shrink-swell 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, Part I

(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 table “Water Management” gives 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; and aquifer-fed

excavated ponds. 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 table 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.

Water Management

(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)

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 in 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 (1) and the

Unified soil classification system (2).

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 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.

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.

Particle size is the effective diameter of a soil particle as measured by

sedimentation, sieving, or micrometric methods. Particle sizes are expressed as

classes with specific effective diameter class limits. The broad classes are sand, silt,

and clay, ranging from the larger to the smaller.

Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter to

2 millimeters in diameter. In the table, the estimated sand content of each soil layer is

given as a percentage, by weight, of the soil material that is less than 2 millimeters in

diameter.

Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05

millimeter in diameter. The estimated silt content of each soil layer is given as a

percentage, by weight, of the soil material that is less than 2 millimeters in diameter.

Clay as a soil separate consists of mineral soil particles that are less than 0.002

millimeter in diameter. The estimated clay content of each soil layer is given as a

percentage, by weight, of the soil material that is less than 2 millimeters in diameter.

The content of sand, silt, and clay affects the physical behavior of a soil. Particle

size is important for engineering and agronomic interpretations, for determination of

soil hydrologic qualities, and for soil classification.

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 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 shrink-swell 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 are shown in the table as the K factor (Kw and Kf) and the T factor.

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) and the

Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of

soil loss by sheet and rill erosion in tons per acre per year. The estimates are based

primarily on percentage of silt, sand, and organic matter and on soil structure and

permeability. Values of K range from 0.02 to 0.69. Other factors being equal, the higher

the value, the more susceptible the soil is to sheet and rill erosion by water.

Erosion factor Kw indicates the erodibility of the whole soil. The estimates are

modified by the presence of rock fragments.

Erosion factor Kf indicates the erodibility of the fine-earth fraction, or the material

less than 2 millimeters in size.

Erosion factor T is an estimate of the maximum average annual rate of soil erosion

by wind or water that can occur without affecting crop productivity over a sustained

period. The rate is in tons per acre per year.

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.
Soil Survey of Okfuskee County, Oklahoma

373

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

Cooperative Extension Service.

Physical Analyses of Selected Soils

The results of physical analyses of several pedons are given in the table “Physical

Properties of Selected Soils, Parts I and II.” The data are for soils sampled at carefully

selected sites. The pedons are representative of the series described in this survey.

Soil samples were analyzed by the Soil Survey Laboratory, Lincoln, Nebraska.

Most determinations, except for those for grain-size analysis and bulk density, were

made on soil material smaller than 2 millimeters in diameter. Measurements reported

as percent or quantity of unit weight were calculated on an ovendry basis. The

methods used in obtaining the data are indicated in the list that follows. The codes in

parentheses refer to published methods.

Clay—(fraction less than 0.002 mm) pipette extraction, weight percentages of all

material less than 2 mm (3A1).

Silt—(0.002-0.05 mm fraction) pipette extraction, weight percentages of all material

less than 2 mm (3A1).

Sand—(0.05-2.0 mm fraction) weight percentages of material less than 2 mm

(3A1).

Bulk density—of less than 2 mm material, saran-coated clods field moist (4A1a), 1

/3 bar (4A1d), ovendry (4A1h).

Water-retention difference—between 1/3 bar and 15 bars for whole soil (4C1).

Water retained—pressure extraction, percentage of ovendry weight of less than 2

mm material; 1/3 or 1/10 bar (4B1), 15 bars (4B2).

Linear extensibility—change in clod dimension based on whole soil (4D).

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 in 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 cationexchange capacity hold fewer cations and may require more frequent applications of

fertilizer than soils having a high cation-exchange capacity. Soils having a high cationexchange capacity can retain cations. The ability to retain cations helps to prevent the

pollution of ground water.

Effective cation-exchange capacity refers to the sum of extractable bases plus

aluminum expressed in terms of milliequivalents per 100 grams of soil. It is determined

for soils that have a pH of less than 5.5.

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 relative to calcium and

magnesium in the water extract from saturated soil paste. 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.

Chemical Analyses of Selected Soils

The results of chemical analysis of several pedons are given in the table “Chemical

Properties of Selected Soils.” The data are for soils sampled at carefully selected sites.

The pedons are representative of the series described in this survey. Soil samples

were analyzed by the Soil Survey Laboratory, Lincoln, Nebraska.

Most determinations, except for those for grain-size analysis and bulk density, were

made on soil material smaller than 2 millimeters in diameter. Measurements reported

as percent or quantity of unit weight were calculated on an ovendry basis. The

methods used in obtaining the data are indicated in the list that follows. The codes in

parentheses refer to published methods.

Organic carbon—wet combustion. Walkley-Black modified acid-dichromate, ferric

sulfate titration (6A1c).

Extractable cations—ammonium acetate pH 7.0, atomic absorption; calcium

(6N2e), magnesium (6O2d), sodium (6P2b), potassium (6Q2b).

Extractable acidity—barium chloride-triethanolamine IV (6H5a).

Cation-exchange capacity—ammonium acetate, pH 7.0, steam distillation (5A8b).

Cation-exchange capacity—sum of cations (5A3a).

Base saturation—sum of cations, TEA, pH 8.2 (5C3).

Base saturation—ammonium acetate, pH 7.0 (5C1).

Reaction (pH)—calcium chloride (8C1f).

Reaction (pH)—1:1 water dilution (8C1f).

Water Features

The table “Water Features” gives estimates of several important water features used

in land use planning that involves engineering considerations. These features are

described in the following paragraphs.

Hydrologic soil groups are groups of soils that, when saturated, have the same

runoff potential under similar storm and ground cover conditions. The soil properties

that affect the runoff potential are those that influence the minimum rate of infiltration in

a bare soil after prolonged wetting and when the soil is not frozen. These properties

include the depth to a seasonal high water table, the intake rate, permeability after

prolonged wetting, and the depth to a very slowly permeable layer. The influences of

ground cover and slope are treated independently and are not taken into account in

hydrologic soil groups.

In the definitions of the hydrologic soil groups, the infiltration rate is the rate at which

water enters the soil at the surface and is controlled by surface conditions. The

transmission rate is the rate at which water moves through the soil and is controlled by

properties of the soil layers.

The four hydrologic soil groups are:

Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly

wet. These consist chiefly of very 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 clayey soils that have a high shrink-swell

potential, soils that have a permanent 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.

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 frequency of ponding generally is expressed as none, rare, occasional, or

frequent. None means no reasonable possibility of ponding. The chance of ponding is

nearly 0 percent in any year. Rare means that ponding is unlikely but is possible under

unusual weather conditions. The chance of ponding is nearly 0 percent to 5 percent in

any year (ponding occurs nearly 0 times to 5 times in 100 years). Occasional means

that ponding is expected infrequently under usual weather conditions. The chance of

ponding is 5 to 50 percent in any year (ponding occurs 5 to 50 times in 100 years).

Frequent means that ponding is likely to occur often under usual weather conditions.

The chance of ponding is more than 50 percent in any year (ponding occurs more than

50 times in 100 years).
Soil Survey of Okfuskee County, Oklahoma

415

Duration is expressed as very brief (less than 2 days), brief (2 to 7 days), long (7 to

30 days), and very long (more than 30 days). The time of year that ponding is most

likely to occur is expressed in months. About two-thirds to three-fourths of all ponding

occurs during the stated period.

The information on ponding is based on evidence of ponded areas as indicated by

debris along high water lines and by other signs of maximum water height.

Also considered are local information about the extent and level of ponding and the

relation of each soil on the landscape to historic ponding. Information on the extent of

ponding based on soil data is less specific than that provided by detailed engineering

surveys that delineate areas that are subject to ponding at specific frequency levels.

Flooding, the temporary covering of the soil surface by flowing water, is caused by

overflow from streams or by runoff from adjacent slopes.

The table gives the frequency and duration of flooding and the time of year when

flooding is most likely to occur. Frequency, duration, and probable dates of occurrence

are estimated.

Frequency generally is expressed as none, rare, occasional, or frequent. None

means no reasonable possibility of flooding. The chance of flooding is nearly 0 percent

in any year. Rare means that flooding is unlikely but is possible under unusual weather

conditions. The chance of flooding is nearly 0 percent to 5 percent in any year

(flooding occurs nearly 0 times to 5 times in 100 years). Occasional means that

flooding is expected infrequently under usual weather conditions. The chance of

flooding is 5 to 50 percent in any year (flooding occurs 5 to 50 times in 100 years).

Frequent means that flooding is likely to occur often under usual weather conditions.

The chance of flooding is more than 50 percent in any year (flooding occurs more than

50 times in 100 years).

Duration is expressed as very brief (less than 2 days), brief (2 to 7 days), long (7 to

30 days), and very long (more than 30 days). The time of year that flooding is most

likely to occur is expressed in months. About two-thirds to three-fourths of all flooding

occurs during the stated period.

The information on flooding 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 level 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.

Soil Features

The table “Soil Features” gives estimates of several important soil features used in

land use planning that involves engineering considerations. These features are

described in the following paragraphs.

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 restrict roots or 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 “Soil Features” 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 is also expressed as low, moderate, or high. It is

based on soil texture, acidity, and amount of sulfates in the saturation extract.

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 gravel, 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.

Aspect. The direction in which a slope faces.

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

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

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

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

principal element of many hillsides. Backslopes in profile are commonly steep, are

linear, and may or may not include cliff segments.

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 cation-exchange capacity.

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

gravel.

Conservation cropping system. Growing crops in combination with needed cultural

and management practices. In a good conservation cropping system, the soilimproving crops and practices more than offset the effects of the soil-depleting

crops and practices. Cropping systems are needed on all tilled soils. Soilimproving 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

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.

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 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 soil-forming 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.

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

tops), blocky (angular or subangular), and granular. Structureless soils are either

single grain (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. Technically, the E horizon. Generally refers to a leached horizon

lighter in color and lower in content of organic matter than the overlying 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. A general term for the top, or highest level, of an upland feature, such as a

hill or mountain. It commonly refers to a higher area that has a gentle slope and is

flanked by steeper slopes.

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.

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 is

generally 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 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 outermost inclined surface at the base of a hill; part of a footslope.

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.

Toxicity (in tables). Excessive amount of toxic substances, such as sodium or sulfur,

that severely hinder establishment of vegetation or severely restrict plant growth.

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.

Unstable fill (in tables). Risk of caving or sloughing on banks of fill material.

Upland (geology). 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. 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.
