How To Use This Soil Survey 

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.

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 2004. Soil names and 

descriptions were approved in September 2005. Unless otherwise indicated, 

statements in this publication refer to conditions in the survey area in 2004. 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 Greer 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.

Foreword 

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

in Oklahoma. 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. 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 is available at the local office of 

the Natural Resources Conservation Service or the Cooperative Extension Service.

This soil survey updates the survey of Greer County published in 1967 (7). It 

provides additional information and shows the soils in greater detail. 

Greer County is in the southwestern part of Oklahoma (fig. 1). Adjacent counties 

are Harmon County on the west, Beckham County on the north, Kiowa County on the 

east, and Jackson County on the south. It has an area of 643 square miles, or 

411,642 acres. Mangum, the county seat, is located is in the south-central part of the 

county. 

General Nature of the Survey Area 

This section provides general information about the survey area. It describes 

history; industry and transportation; physiography and drainage; natural resources; 

and climate. 

Figure 1.—Location of Greer County in Oklahoma.
History 

Burna Cole, Museum of the Western Prairie, Altus, Oklahoma helped prepare this section. 

From the time of Coronado’s exploration of the plains of Texas, the Oklahoma 

Panhandle, and western Kansas in 1542, the area of present day Greer County has 

been fought over and in dispute between nations. The region was claimed by Spain 

as part of the “right of exploration” based on Coronado’s expedition. France laid claim 

to the region also, as a “right of exploration,” when in 1673, Father Marquette and 

Louis Jolliet followed the course of the Mississippi as far south as the Arkansas River 

and claimed the river and all its drainage for France. Following the French and Indian 

War, France ceded its territory west of the Mississippi River to Spain. Napoleon, 

however, negotiated for the return of the territory but then in 1803 sold the region as 

the Louisiana Purchase to the United States. 

Always in dispute, first between the French and the Spanish, the boundaries 

became even more hotly contested when the more aggressive Americans became 

Spain’s neighbors. France had told the United States it would receive the boundaries 

just as France had received them from Spain. It was bounded on the east by the 

Mississippi River, on the south by the Gulf of Mexico, on the west by the Sabine 

River, the Red River, the Arkansas River and the Continental Divide. But the Red 

River was a problematic boundary. In spite of the fact that Pedro Vial had mapped 

the Red River to its headwaters in the Palo Duro Canyon in 1785, several expeditions 

by the United States to locate the headwaters failed. The United States finally 

secured an accurate mapping of the river in 1852 by Captain Randolph Marcy and 

Captain George McCellan; however, they did mis-locate the 100th meridian at that 

time. The most southern and westerly flowing branch, known as the Prairie Dog 

branch was deemed by the United States as the boundary with Mexico. Mexico and 

later the Republic of Texas regarded the North Fork of the Red River to be the 

principal river bed and therefore the boundary. Texas proceeded to organize a 

county and named it Greer after John Greer, Lt. Governor of Texas. 

Following the Civil War, John Lytle opened the Great Western Cattle Trail through 

the region. The trail was in use from 1874 until about 1888. An average of 300,000 

head of cattle moved over the trail annually, along with approximately 7,000 horses 

and 1,000 men. 

When President Harrison signed the Organic Act authorizing the organization of 

Oklahoma Territory in 1890, He also directed that suit be brought against Texas in 

the United States Supreme Court to settle once and for all the question of boundary 

and jurisdiction. In 1896, the Supreme Court found in favor of the United States and 

against Texas. A region containing 1.4 million acres of land was added to the 

Oklahoma Territory. At statehood in 1907, Old Greer County was divided into present 

day Greer, Harmon, Jackson, and the southern half of Beckham counties. 

Settlement of Old Greer County was primarily emigration by Texans into the 

region. Cattle ranches such as the Cross-S, owned by the Eddleman brothers, IkardHarold Cattle, and Franklin Cattle all ran their livestock on the open plains, 

meanwhile nesters (squatters, sod-busters, and farmers) drifted into the area looking 

for a better future. Texas also had offered land to veterans of the Texas War of 

Independence from Mexico in 1836. One recipient of such a grant was Captain A. S. 

Mangum for whom the town of Mangum is named. Once the land became a part of 

the Oklahoma Territory, the United States Government allowed those in residence to 

file on 160 acre homesteads and the option to purchase an additional 160 acres. 

Industry and Transportation 

Greer County has adequate transportation facilities. U.S. Highway 283 and State 

Highway 34 extend north to south through the center of the county. State Highway 9

extends generally east to west through the center of the county. State Highway 6 

extends along the eastern side of the county from north to south. Several county 

roads have been surfaced and are suitable for all-weather travel. An airport facility is 

located at Mangum. 

Agriculture provides a major part of the income in Greer County. Cotton, peanuts, 

alfalfa, livestock, and related products are the principal sources. 

The oil and gas industry also provide a source of income in the county. A granite 

quarry and state correctional facility are located in the town of Granite. 

Physiography and Drainage 

Greer County contains parts of three Major Land Resource Areas within its 

boundaries. The western part of the county is in the Central Rolling Red Plains—

western part (78B). The remainder of the county is located in the Central Rolling Red 

Plains—eastern part (78C) with the exception of a small portion of the east-central 

part which is in the Wichita Mountains (82B). 

Elevation ranges from 1,410 to 2,303 feet. The highest point in the county is 

located at the top of Walsh Mountain northwest of the town of Granite. The lowest 

point in the county is located at the southern boundary where the Salt Fork of the 

Red River leaves the county. 

The relief in Greer County can be divided into four basic topographic types. The 

eastern and central parts of the county are characterized by nearly level and gently 

sloping alluvial terraces of fine and moderately fine textured soils. These soils are 

very productive and most are cultivated. 

The western part of the county is characterized by nearly level to moderately 

sloping hills formed from the interbedded gypsum, dolomite, claystone, and 

sandstone of Permian age. This area contains karst topography that formed in 

gypsum and dolomite bedrock with numerous sinkholes. Most of the soils in this area 

were formed from the Permian bedrock or local alluvium and range from very shallow 

to very deep to bedrock. They are moderately productive but are susceptible to 

erosion when cultivated. Many acres in this area have been reseeded to native grass 

or tame pasture species. 

The third type of relief is characterized by steep escarpments, rolling hills, and 

areas of badlands which runs generally from north to south through the central part of 

the county. This area is a transitional zone from the rolling uplands in the west to the 

alluvial terraces in the east. The soils in this region are generally clayey and range 

from shallow to very deep to bedrock. These soils have low to moderate productivity 

and are susceptible to erosion when cultivated. 

The fourth type occurs in the eastern and southwestern parts of the county. 

These areas are characterized by gently sloping to steep sand dunes and very gently 

sloping alluvial terraces. The soils in this area are mainly very deep loamy or sandy 

soils formed in alluvial or windblown sediments and range from low to moderately 

high productivity. 

The entire county is located in the Red River Basin and the general drainage 

pattern is from west to east in the western part of the county and north to south in the 

eastern part of the county. There are three major rivers and several smaller streams 

that comprise the drainage of Greer County. The North Fork of the Red River flows 

generally from north to south, is the eastern boundary of the county, and flows into 

the Red River. The Salt Fork of the Red River flows from west to east in the southern 

part of the county to about Mangum then turns and flows south into the Red River. 

The Elm Fork of the River flows from west to east through the central part of the 

county and flows into the North Fork of the Red River just below Lake Altus. 

There are several smaller tributaries which flow into the larger rivers. Deer Creek 

and Haystack Creek drain the northwestern part of the county and flow into the Elm 

Soil Survey of Greer County, Oklahoma

Fork River. Lake Creek drains the northeastern part of the county and flows into the 

North Fork of the Red River. Russell Hollow Creek drains the southwestern part of 

the county and flows south into Jackson County where it joins the Salt Fork of the 

Red River. 

Natural Resources 

The natural resources of the county are mainly soil, water, petroleum products, 

and scenic beauty. 

The soil and available water are the most important natural resources of the 

county. A large acreage in the county is productive and has a high potential for native 

grasses and for cotton, peanuts, and alfalfa. Rangeland makes up about forty 

percent of the county. In the past, overgrazing and erosion damaged much of the 

rangeland. Proper management can increase the production of native grasses. 

Irrigation has become an important factor in the production of agricultural crops in 

Greer County. Approximately 11,740 acres are irrigated or have the potential for 

irrigation in Greer County with cotton, alfalfa, and peanuts being the main crops. 

Water for irrigation in Greer County comes mainly from two sources, Lake Altus and 

underground wells. 

Lake Altus via a system of canals managed by the Lugert-Altus Irrigation District, 

supplies water to approximately 46,000 acres between the Salt and North Forks of 

the Red River. Approximately 2,517 acres of this is located in southeastern Greer 

County. Most of the water from the Lugert-Altus Irrigation District is applied by canals 

and furrows. 

Wells supply water for irrigation from underground aquifers located in sand and 

gravel deposits along some of the major streams and rivers in the county. Generally, 

these aquifers supply water with high enough quality for human or livestock 

consumption. Well water is applied by both furrow and sprinkler systems. The 

number of center-pivot sprinkler systems has been increasing because they require 

less labor and increase water efficiency 

Oil and gas wells have been drilled and are operating in the county. Gypsum 

beds outcrop in the northwest and southwestern parts, and some areas are mined for 

road gravel. 

Greer County is rich in scenic beauty. It has granite mountains in the eastern part 

of the county, grass-covered sand dunes in the northeastern part of the county 

coupled with highly dissected canyons and small buttes in the northwestern and 

southwestern parts. 

Climate 

Prepared by the Natural Resources Conservation Service, National Water and Climate Center, Portland, 

Oregon. 

The climate tables were created using data from the climate station at Mangum 

Research Station, Oklahoma. 

Thunderstorm days, relative humidity, percent sunshine, and wind information are 

estimated from First Order station Amarillo, Texas. 

The table, “Temperature and Precipitation,” provides data on temperature and 

precipitation for the survey area as recorded at Mangum Research Station in the 

period 1971 to 2000. 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 41.1 degrees F and the average daily 

minimum temperature is 27.6 degrees. The lowest temperature on record, which 

occurred at Mangum Research Station on December 23, 1989, was -11 degrees. In 

summer, the average temperature is 81.7 degrees and the average daily maximum

temperature is 96.0 degrees. The highest temperature, which occurred at Mangum 

Research Station on July 3, 1980, was 117 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 (50 degrees F). The normal monthly accumulation is used to schedule 

single or successive plantings of a crop between the last freeze in spring and the first 

freeze in fall. 

The average annual total precipitation is 27.91 inches. Of this, about 21.9 inches, 

or 78 percent, usually falls in April through October. The growing season for most 

crops falls within this period. The heaviest 1-day rainfall during the period of record 

was 6.45 inches at Mangum Research Station on October 20, 1983. Thunderstorms 

occur on about 49 days each year, and most occur between May and August. 

The average seasonal snowfall is 3.2 inches. The greatest snow depth at any one 

time during the period of record was 8 inches recorded on February 10, 1986. On an 

average, about 1 day per year has at least 1 inch of snow on the ground. The 

heaviest 1-day snowfall on record was 7.0 inches recorded on March 10, 1948. 

The average relative humidity in mid-afternoon is about 40 percent. Humidity is 

higher at night, and the average at dawn is about 73 percent. The sun shines 78 

percent of the time in summer and 69 percent in winter. The prevailing wind is from 

the south or southwest. Average wind speed is highest, between 15 and 16 miles per 

hour, in March and April.

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 fieldobserved 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. 

Soil Survey of Greer County, Oklahoma

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 

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. 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 may 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.

Formation of the Soils 

This section describes the factors of soil formation and how they relate to the 

soils in Greer County. 

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 Greer County formed in material weathered from 

sandstone, clay, shale, gypsum, and dolomite. 

Alluvial sediment is extensive along the streams and rivers in the county. The 

kind of sediment deposited and the kinds of soil that formed in it depend largely on 

the source of the sediment and the velocity of the streams. 

Climate 

Greer County has a dry, subhumid climate. The climate is fairly uniform 

throughout the county; differences between soils cannot be attributed to differences 

in climate based on the present climatic regime. The temperatures and amount of 

moisture have been sufficient to promote the formation of distinct layers in many of 

the soils. Soil leaching is slow to moderate. The physical abrasion and redistribution 

of materials by wind action contributes to soil formation. Cold temperatures occur 

often enough and long enough for freezing and thawing to alter materials. 

Living Organisms 

Plants, burrowing animals, insects, and microorganisms have a direct influence 

on the formation of soils. Differences among native grasses and woody plants in the 

county have resulted in differential losses and gains of organic matter and plant 

nutrients and indifferences in soil structure and porosity. Soils that formed under 

prairie vegetation, such as those of the Roark and Tipton series, have a dark grayish 

brown surface layer and a moderately high content of organic matter. Soils that 

formed under woody vegetation, such as those of the Devol series, have a brown 

surface layer and a low content of organic matter. 
Topography 

Relief influences the formation of the soils mainly by affecting water movement, 

erosion, soil temperature, and kind of plant cover. In Greer County, the resistance of 

underlying formations to weathering and geological erosion determines relief. The 

topography of the western part of Greer County is gently rolling uplands with very 

gently sloping to moderately sloping hills. The soils formed on summits and shoulders 

of hills are generally very shallow to moderately deep to bedrock. The soils formed on 

side and foot slopes are generally deep or very deep to bedrock. The eastern part of 

Greer County is nearly level to very gently sloping terraces with occasional low hills. 

The soils are generally very deep to bedrock, except on the summits and shoulders 

of hills, which are moderately deep or deep to bedrock. A transitional zone between 

these areas is characterized by steep rock escarpments and areas of badlands. 

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. 

The soils in Greer County range from young to old. Hollister and Tillman soils are 

examples of old soils. Grandfield soils are younger, but they have well expressed 

horizons. Lincoln and Gracemont soils are young soils that formed in recent 

sediments on flood plains and show little horizon development.

Classification of the Soils 

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

has six categories. 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. “Classification of the Soils,” shows the classification 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 Entisol. 

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 Fluvent (Fluv, meaning flood 

plain, plus ent, from Entisol). 

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; type of saturation; 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 Ustifluvents (Usti, meaning dryness, plus fluvent, 

the suborder of Entisols that occurs on flood plains).

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

intergrades or extragrades. The typic subgroup 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 

taxonomic class. Each subgroup is identified by one or more adjectives preceding the 

name of the great group. The adjective Typic identifies the subgroup that typifies the 

great group. An example is Typic Ustifluvents.

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, 

mineralogy class, cation-exchange activity class, soil temperature regime, soil depth, 

and reaction class. A family name consists of the name of a subgroup preceded by 

terms that indicate soil properties. An example is sandy, mixed, thermic Typic 

Ustifluvents. 

SERIES. The series consists of soils within a family that have horizons similar in 

color, texture, structure, reaction, consistence, mineral and chemical composition, 

and arrangement in the profile. 

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” (3). Many of the 

technical terms used in the descriptions are defined in “Soil Taxonomy” (5). 
Classification of the Soils 

A '*' in the first column indicates that the component kind is a taxadjunct to the series. A '%' in 

the first column indicates that the component kind is a miscellaneous area. A '&' in the first column 

indicates that the component kind is a family. (See text for a description of those characteristics 

that are outside the range of the series)

Detailed Soil Map Units 

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 “Use and Management” 

section of this survey. 

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 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 soils. They may or may not be mentioned in the map unit 

description. Other 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, minor components. 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 

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

descriptions. A few 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, Aspermont silt loam, 3 to 5 percent slopes, 

is a phase of the Aspermont series. 

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

These map units are complexes, associations, 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. Burford-Spikebox outcrop complex, 3 to 12 percent slopes, is an 

example. 

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

material and support little or no vegetation. Rock outcrop, granite, is an example. 

Miscellaneous areas are shown on the soil maps. Areas that are too small to be 

shown are identified by a special symbol on the soil maps. 

The table, “Acreage and Proportionate Extent of the Soils,” provides the acreage 

and proportionate extent of each map unit. Other tables (see “Summary of Tables”) 

show 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.

Use and Management of the Soils 

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 acquisition of 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.” 

Agronomy 

General management concerns affecting crops, hay, and pasture are identified in 

this section. The system of land capability classification used by the Natural Resources 

Conservation Service is explained, 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 that are designed to show suitability and limitations of groups of soils for 

rangeland, for woodland, or for engineering purposes. 

In the capability system, as described in “Land Capability Classification” (8), soils 

generally are grouped at three levels: capability class, subclass, and unit. These levels 

indicate the degree and kinds of limitations affecting mechanized farming systems that 

produce the more commonly grown field crops, such as corn, small grain, cotton, hay, 

and field-grown vegetables. Only class and subclass are used in this survey. 

Capability classes, the broadest groups, are designated by Arabic numerals 1 

through 8. The numerals indicate progressively greater limitations and narrower 

choices for practical use. 

If properly managed, soils in classes 1, 2, 3, and 4 are suitable for the mechanized 

production of commonly grown field crops and for pasture and woodland. The degree of 

the soil limitations affecting the production of cultivated crops increases progressively 

from class 1 to class 4. The limitations can affect levels of production and the risk of 

permanent soil deterioration caused by erosion and other factors. 

Soils in classes 5, 6, and 7 are generally not suited to the mechanized production of 

commonly grown field crops without special management, but they are suitable for 

plants that provide a permanent cover, such as grasses and trees. The severity of the 

soil limitations affecting crops increases progressively from class 5 to class 7. The local 

office of the Natural Resources Conservation Service or the Cooperative Extension 

Service can provide guidance on the use of these soils as cropland. 

Areas in class 8 are generally not suitable for crops, pasture, rangeland, or 

woodland. These areas may have potential for other uses, such as recreational 

facilities and wildlife habitat. 

Capability subclasses identify the dominant kind of limitation in the class. They are 

designated by adding a small letter, e, w, s, or c, to the class numeral, for example, 2e. 

The letter e shows that the main hazard is the risk of erosion unless a close-growing 

plant cover is maintained; w shows that water in or on the soil interferes with plant 

growth or cultivation (in some soils the wetness can be partly corrected by artificial 

drainage); s shows that the soil is limited mainly because it is shallow, droughty, or 

stony; and c, used in only some parts of the United States, shows that the chief 

limitation is climate that is very cold or very dry. 

There are no subclasses in class 1 because the soils of this class have few 

limitations. Class 5 contains only the subclasses indicated by w, s, or c because the 

soils in class 5 are subject to little or no erosion. They have other limitations that 

restrict their use mainly to pasture, rangeland, woodland, wildlife habitat, or recreation. 

The capability classification of each map unit is shown in the tables, “Land Capability 

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

Pasture.” 

Soil Survey of Greer County, Oklahoma

132
Estimated Yields of Crops, Pasture, and Hay 

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

level of management are shown in tables, “Land Capability and Yields per Acre of 

Crops” and “Land Capability and Yields per Acre of Hay and Pasture.” In any given 

year, yields may be higher or lower than those indicated in the tables because of 

variations in rainfall and other climatic factors. The land capability classification of each 

map unit also is shown in the tables. 

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. 

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

Yields per Acre of Hay and Pasture.”

Land Capability and Yields per Acre of Hay and Pasture 

(Yields in the "N" columns are for nonirrigated areas; those in the "I" columns are for irrigated 

 areas. Yields are those that can be expected under a high level of management. Absence of a 

 yield indicates that the soil is not suited to the crop or the crop generally is not grown on 

 the soil.)

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 

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. 

Prime farmland soils may presently be used as cropland, pasture, rangeland, or 

woodland or for other purposes. They either are used for food and fiber or are available 

for these uses. Urban or built-up land, public land, and water areas cannot be 

considered prime farmland. Urban or built-up land is any contiguous unit of land 10 

acres or more in size that is used for such purposes as housing, industrial, and 

commercial sites, sites for institutions or public buildings, small parks, golf courses, 

cemeteries, railroad yards, airports, sanitary landfills, sewage treatment plants, and 

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 172,000 acres, or about 42 percent of the survey area, meets the requirements 

for prime farmland. The map units in the survey area that meet the requirements for 

prime farmland are listed in the table, “Prime Farmland.” The location of each map unit is 

shown on the detailed soil maps. 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 these tables, the effluent in lagoons and storage 

ponds is from facilities used to treat or store food-processing wastewater or domestic or 

animal waste. Domestic and food-processing wastewater is very dilute, and the effluent 

from the facilities that treat or store it commonly is very low in content of carbonaceous 

and nitrogenous material; the content of nitrogen commonly ranges from 10 to 30 

milligrams per liter. The wastewater from animal waste treatment lagoons or storage 

ponds, however, has much higher concentrations of these materials, mainly because the 

manure has not been diluted as much as the domestic waste. The content of nitrogen in 

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

is applied, checks should be made to ensure that nitrogen, heavy metals, and salts are 

not added in excessive amounts. 

The ratings in the tables are for waste management systems that not only dispose of 

and treat organic waste or wastewater but also are beneficial to crops (application of 

manure and food-processing waste, application of sewage sludge, and disposal of 

wastewater by irrigation) and for waste management systems that are designed only for 

the purpose of wastewater disposal and treatment (overland flow of wastewater, rapid 

infiltration of wastewater, and slow rate treatment of wastewater). 

The ratings are both verbal and numerical. Rating class terms indicate the extent to 

which the soils are limited by all of the soil features that affect agricultural waste 

management. Not limited indicates that the soil has features that are very favorable for 

the specified use. Good performance and very low maintenance can be expected. 

Somewhat limited indicates that the soil has features that are moderately favorable for 

the specified use. The limitations can be overcome or minimized by special planning, 

design, or installation. Fair performance and moderate maintenance can be expected. 

Very limited indicates that the soil has one or more features that are unfavorable for the 

specified use. The limitations generally cannot be overcome without major soil 

reclamation, special design, or expensive installation procedures. Poor performance and 

high maintenance can be expected. 

Numerical ratings in the tables indicate the severity of individual limitations. The 

ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate 

gradations between the point at which a soil feature has the greatest negative impact on 

the use (1.00) and the point at which the soil feature is not a limitation (0.00). 

Application of manure and food-processing waste not only disposes of waste material 

but also can improve crop production by increasing the supply of nutrients in the soils 

where the material is applied. Manure is the excrement of livestock and poultry, and foodprocessing 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 solid, slurry, or liquid. Their nitrogen content varies. A high content of nitrogen limits 

the application rate. Toxic or otherwise dangerous wastes, such as those mixed with the 

lye used in food processing, are not considered in the ratings. 

The ratings are based on the soil properties that affect absorption, plant growth, 

microbial activity, erodibility, the rate at which the waste is applied, and the method by 

Soil Survey of Greer County, Oklahoma

151
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. Most of the water reaches the 

collection ditch, some is lost through evapotranspiration, and a small amount may 

percolate to the ground water. 

The ratings in the table are based on the soil properties that affect absorption, plant 

growth, microbial activity, and the design and construction of the system. Reaction and

the cation-exchange capacity affect absorption. Reaction, salinity, and the sodium 

adsorption ratio affect plant growth and microbial activity. Slope, permeability, depth to a 

water table, ponding, flooding, depth to bedrock or a cemented pan, stones, and cobbles 

affect design and construction. Permanently frozen soils are unsuitable for waste 

treatment. 

Rapid infiltration of wastewater is a process in which wastewater applied in a level 

basin at a rate of 4 to 120 inches per week percolates through the soil. The wastewater 

may eventually reach the ground water. The application rate commonly exceeds the rate 

needed for irrigation of cropland. Vegetation is not a necessary part of the treatment; 

hence, the basins may or may not be vegetated. The thickness of the soil material 

needed for proper treatment of the wastewater is more than 72 inches. As a result, 

geologic and hydrologic investigation is needed to ensure proper design and 

performance and to determine the risk of ground-water pollution. 

The ratings in the table are based on the soil properties that affect the risk of pollution 

and the design, construction, and performance of the system. Depth to a water table, 

ponding, flooding, and depth to bedrock or a cemented pan affect the risk of pollution and 

the design and construction of the system. Slope, stones, and cobbles also affect design 

and construction. Permeability and reaction affect performance. Permanently frozen soils 

are unsuitable for waste treatment. 

Slow rate treatment of wastewater is a process in which wastewater is applied to land 

at a rate normally between 0.5 inch and 4.0 inches per week. The application rate 

commonly exceeds the rate needed for irrigation of cropland. The applied wastewater is 

treated as it moves through the soil. Much of the treated water may percolate to the 

ground water, and some enters the atmosphere through evapotranspiration. The applied 

water generally is not allowed to run off the surface. Waterlogging is prevented either 

through control of the application rate or through the use of tile drains, or both. 

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.

Rangeland 

Mark Moseley, Range Conservationist, Natural Resources Conservation Service, Stillwater, Oklahoma, 

helped prepare this section. 

Range and native pasture provide forage for livestock in the survey area. 

Range is defined as land on which the native vegetation (the climax, or natural 

potential, plant community) is predominantly grasses, grasslike plants, forbs, and shrubs 

suitable for grazing and browsing. Range includes natural grasslands, savannas, many 

wetlands, some deserts, tundra, and certain shrub and forb communities. Range receives 

no regular or frequent cultural treatment. The composition and production of the plant 

community are determined by soil, climate, topography, overstory canopy, and grazing 

management. 

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 40 percent of the land in Greer County. There has been a 

recent trend to reseed many areas of marginal cropland with a mixture of native grass 

species. The range is used primarily for grazing by domestic cattle; however, its 

importance as wildlife habitat is becoming increasingly important as more landowners 

lease the hunting rights on their range as an additional source of income. 

The rangeland in Greer County originally produced a wide variety of tall and midsized grasses interspersed with an abundance of forbs that evolved under the collective 

influence of ungulate grazing, fire, variable climatic events, insects, and rodents and 

other wildlife. Effective range management practices that mimic the historical 

management can help to maintain or re-establish these high quality plants. 

Four types of rangeland exist in Greer County. The first type is in the east central and 

southeastern parts of the county where the soils formed in very deep, loamy, alluvial 

sediments. This area is typified by broad flats and gently sloping and sloping uplands. 

The soils support predominantly tall grasses, and potential productivity is high. The 

second type is in the northeastern and southern parts of the county along areas parallel 

to the North Fork of the Red River and the Salt Fork of the Red River. In these areas the 

soils formed in deep, sandy and loamy sediments. Hummocky sand dunes and flat 

depressions typify these areas, and wind erosion is a hazard if adequate cover is not 

maintained on the surface of the soil. Soils in these areas support tall and mid grasses 

with scattered woody shrubs, and potential productivity is moderate. The third type is in 

the central and northwestern parts of the county. The soils are loamy and are shallow to 

very deep over sandstone or alluvial sediment. These areas are typified by rolling hills 

and a few flat-topped ridges and canyons. The soils support a mixture of tall, mid, and 

short grasses, and potential productivity is moderate to high. The fourth type is in the 

south central and western parts of the county where the soils are loamy or clayey and are 

shallow to moderately deep over gypsum or shale. This area is typified by steep 

escarpments and gently sloping to sloping uplands. The soils support short and mid 

grasses. Potential productivity is low because of the shallow root zones. 

Approximately 75 percent of the annual production of forage occurs from April 

through July following the rains in spring and early summer. A second, smaller growth 

period may occur in the fall if 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. Only those soils that are used as rangeland or are suited to use as 

rangeland are listed. Explanation of the column headings in this table follows.

An ecological site for rangeland is a distinctive kind of land and vegetation with 

specific physical characteristics that make 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 time, the combination of 

plants best suited to a particular soil and climate has become 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 and online the internet at 

http://www.nrcs.usda.gov/technical/efotg/ 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 range that is supporting the potential natural plant community. 

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 airdry vegetation for favorable, normal, and unfavorable years. In a favorable year, the 

amount and distribution of precipitation and the temperature 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 18 shows a typical 

growth curve that represents the percentage of total growth that occurs each month for 

native vegetation and other forage. 

Dry weight is the total annual yield per acre. Yields are adjusted to a common 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. Rangeland composition lists the anticipated percentage of the total 

annual production 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 

The similarity index indicates on a percentage basis the extent to which the present 

plant community resembles a specified vegetative state on an ecological site. NRCS 

uses similarity index two ways. 

The first use compares the present vegetation on an ecological site to the presumed 

historic vegetation for that site. A similarity index of 70 would suggest that the present 

plant community contains 70 percent of the presumed historic plant community for that 

site. This comparison provides a basis for examining the extent and direction of changes 

that have taken place between current vegetation and historic vegetation. 

The second use measures how near the current plant community is to the landowners 

goal for the land. The management goal for rangeland is not necessarily a similarity index 

of 100 as compared to the historic plant community. Therefore, the similarity index can 

represent the percentage of the plant community that resembles a desired plant 

community.

185
Figure 18.—Typical growth curves for various kinds of forage in Greer County. The growth curve for 

each kind of forage indicates the percentage of the total annual growth that occurs each month. 

Abnormal disturbances that can change the natural plant community include repeated 

overuse by livestock, excessive burning, erosion, and cultivation. Grazing animals select 

the most palatable plants. These plants eventually die if they are continually grazed at a 

severity that does not allow for recovery. A very severe disturbance can completely 

destroy the natural community. Under such conditions, the abundance of less desirable 

plants, such as annuals and weed-like plants, can increase. If the plant community and 

the soils have not deteriorated significantly and proper range management is applied, the 

site eventually can return to predominantly natural plants. 

Knowledge of the ecological site is necessary as a basis for planning and applying 

the management needed to maintain or improve the desired plant community for selected 

uses. Such information is needed to support management objectives, planned grazing 

systems, stocking rates, and wildlife management practices; to improve the potential of 

an area for recreational uses; and to improve the condition of watersheds. 

Rangeland Management 

Rangeland management requires knowledge of the kind of soils 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 range management practices used in Greer County include proper grazing use, 

deferred grazing, and planned grazing systems. They also include properly located stockwater developments and fences and a planned distribution of salt and feed. If undesirable 

plants become dominant, range seeding, brush management, or prescribed burning 

should be considered.

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 18. The percent growth that can be safely grazed each 

month without substantially reducing the total yield for each kind of plant is illustrated. 

Range management includes four major considerations: 

Grazing distribution which is achieved by managing livestock to graze all parts of the 

grazing unit equally. 

Selective grazing which occurs because animals graze preferred plants to balance 

their diets. If selective grazing occurs repeatedly, the preferred plants are damaged. 

Proper stocking rates which are achieved by balancing animal numbers with forage 

production. 

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. 

The setting of stocking rates is not an exact science because there are influences 

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

production. Some general rules, however, can be helpful. To maintain a nutritional cover 

of plants, about 50 percent of the annual growth of the 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 

deterioration caused by climatic variations. Because of these factors, a safe initial 

stocking rate should be calculated on the basis of 25 percent of the total annual growth, 

by weight, of the vegetation. 

For example, production could be 2,800 pounds of air-dry grasses, forbs, and woody 

species for an average season on a Loamy Prairie ecological site with a similarity index 

above 70 to the historic plant community. Twenty-five percent of this production would be 

700 pounds. 

A 1,000-pound cow and her calf is equivalent to one animal unit (AU) and consume 

about 2.6 percent of her body weight (26 pounds) of forage per day. Therefore, in 1 

month an animal unit would 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 700 pounds (the forage allocation) by 26 pounds (the forage required per day 

for 1 animal unit) suggests that 1 acre of Loamy Prairie ecological site with a similarity 

index of 70 would feed one cow and calf for 27 days. To convert forage available from 1 

acre to animal unit months (AUM), the available forage (700 pounds) is divided by the 

amount required to feed 1 animal unit for 1 month (790 pounds). One acre would provide 

0.88 AUM of grazing. Therefore, 14 acres would feed one cow and calf for 12 months. 

Another approach is to calculate the annual forage needs of an animal unit (790 

pounds times 12 months equals 9,480 pounds). Dividing the 700 pounds of usable forage 

per acre into the 9,480 pounds needed by the cow and calf reveals that approximately 14 

acres would be needed for one cow and calf annually. Stocking rate calculations should 

be adjusted for animal size, grazing system, and grazing season. 

More information about planning a grazing program is available from the local office 

of the Natural Resources Conservation Service.

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 lowand high-growing broadleaf and coniferous trees and shrubs provide the most protection. 

Field windbreaks are narrow plantings made at right angles to the prevailing wind and 

at specific intervals across the field. The interval depends on the erodibility of the soil. 

Field windbreaks protect cropland and crops from wind, help to keep snow on the fields, 

and provide food and cover for wildlife. 

Environmental plantings help to beautify and screen houses and other buildings and 

to abate noise. The plants, mostly evergreen shrubs and trees, are closely spaced. To 

ensure plant survival, a healthy planting stock of suitable species should be planted 

properly on a well prepared site and maintained in good condition. 

Windbreaks are often planted on land that did not originally support trees. Knowledge 

of how trees perform on such land can be gained only by observing and recording the 

performance of trees that have been planted and have survived. Many popular windbreak 

species are not indigenous to the areas in which they are planted. 

Each tree or shrub species has certain climatic and physiographic limits. Within these 

parameters, a tree or shrub may grow well or grow poorly, depending on the 

characteristics of the soil. Each tree or shrub has definable potential heights in a given 

physiographic area and under given climatic conditions. Accurate definitions of potential 

heights are necessary when a windbreak is planned and designed. 

The table, “Windbreaks and Environmental Plantings,” shows the height that locally 

grown trees and shrubs are expected to reach in 20 years on various soils. The estimates 

in this table are based on measurements and observation of established plantings that 

have been given adequate care. They can be used as a guide in planning windbreaks 

and screens. Additional information on planning windbreaks and screens and planting 

and caring for trees and shrubs can be obtained from local offices of the Natural 

Resources Conservation Service or the Cooperative Extension Service or from a 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 tables indicate the severity of individual limitations. The 

ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate 

gradations between the point at which a soil feature has the greatest negative impact on 

the use (1.00) and the point at which the soil feature is not a limitation (0.00). 

The ratings in the tables are based on restrictive soil features, such as wetness, 

slope, and texture of the surface layer. Susceptibility to Flooding is considered. Not 

considered in the ratings, but important in evaluating a site, are the location and 

accessibility of the area, the size and shape of the area and its scenic quality, vegetation, 

access to water, potential water impoundment sites, and access to public sewer lines. 

The capacity of the soil to absorb septic tank effluent and the ability of the soil to support 

vegetation also are important. Soils that are subject to Flooding are limited for 

recreational uses by the duration and intensity of Flooding and the season when Flooding 

occurs. In planning recreational facilities, onsite assessment of the height, duration, 

intensity, and frequency of flooding is essential. 

The information in 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 this table.)

Engineering 

This section provides information for planning land uses related to urban development 

and to water management. Soils are rated for various uses, and the most limiting features 

are identified. Ratings are given for building site development, sanitary facilities, 

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 similar soils. 

The information in the tables, along with the soil maps, the soil descriptions, and other 

data provided in this survey, can be used to make additional interpretations. 

Some of the terms used in this soil survey have a special meaning in soil science and 

are defined in the Glossary. 

Sanitary Facilities 

The 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. 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 

Soil Survey of Greer County, Oklahoma

262
features that are unfavorable for the specified use. The limitations generally cannot be 

overcome without major soil reclamation, special design, or expensive installation 

procedures. Poor performance and high maintenance can be expected. 

Numerical ratings in the tables indicate the severity of individual limitations. The 

ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate 

gradations between the point at which a soil feature has the greatest negative impact on 

the use (1.00) and the point at which the soil feature is not a limitation (0.00). 

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. 

Rating class terms indicate the extent to which the soils are limited by all of the soil 

features that affect building site development. Not limited indicates that the soil has 

features that are very favorable for the specified use. Good performance and very low 

maintenance can be expected. Somewhat limited indicates that the soil has features that 

are moderately favorable for the specified use. The limitations can be overcome or 

minimized by special planning, design, or installation. Fair performance and moderate 

maintenance can be expected. Very limited indicates that the soil has one or more 

features that are unfavorable for the specified use. The limitations generally cannot be 

overcome without major soil reclamation, special design, or expensive installation 

procedures. Poor performance and high maintenance can be expected. 

Numerical ratings in the tables indicate the severity of individual limitations. The 

ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate 

gradations between the point at which a soil feature has the greatest negative impact on 

the use (1.00) and the point at which the soil feature is not a limitation (0.00). 

Dwellings are single-family houses of three stories or less. For dwellings without 

basements, the foundation is assumed to consist of spread footings of reinforced 

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

penetration, whichever is deeper. For dwellings with basements, the foundation is 

assumed to consist of spread footings of reinforced concrete built on undisturbed soil at a 

depth of about 7 feet. The ratings for dwellings are based on the soil properties that affect 

the capacity of the soil to support a load without movement and on the properties that 

affect excavation and construction costs. The properties that affect the load-supporting 

capacity include depth to a water table, ponding, flooding, subsidence, linear extensibility 

(shrink-swell potential), and compressibility. Compressibility is inferred from the Unified 

classification. The properties that affect the ease and amount of excavation include depth 

to a water table, ponding, flooding, slope, depth to bedrock or a cemented pan, hardness 

of bedrock or a cemented pan, and the amount and size of rock fragments. 

Small commercial buildings are structures that are less than three stories high and do 

not have basements. The foundation is assumed to consist of spread footings of 

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

maximum frost penetration, whichever is deeper. The ratings are based on the soil 

properties that affect the capacity of the soil to support a load without movement and on 

the properties that affect excavation and construction costs. The properties that affect the 

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 trafficsupporting capacity. The properties that affect the ease of excavation and grading are 

depth to bedrock or a cemented pan, hardness of bedrock or a cemented pan, depth to a 

water table, ponding, flooding, the amount of large stones, and slope. The properties that 

Soil Survey of Greer County, Oklahoma

289
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,” provides 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 this table, only the likelihood of finding material in suitable quantity is 

evaluated. The suitability of the material for specific purposes is not evaluated, nor is 

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 tables. The numerical ratings given after the specified features indicate 

the degree to which the features limit the soils as sources of topsoil, reclamation material, 

or roadfill. The lower the number, the greater the limitation. 

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. 

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. 

Soil Survey of Greer County, Oklahoma

312
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).

(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,” provides 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 tables indicate the severity of individual limitations. The 

ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate 

gradations between the point at which a soil feature has the greatest negative impact on 

the use (1.00) and the point at which the soil feature is not a limitation (0.00). 

Pond reservoir areas hold water behind a dam or embankment. Soils best suited to 

this use have low seepage potential in the upper 60 inches. The seepage potential is 

determined by the permeability of the soil and the depth to fractured bedrock or other 

permeable material. Excessive slope can affect the storage capacity of the reservoir 

area. 

Embankments, dikes, and levees are raised structures of soil material, generally less 

than 20 feet high, constructed to impound water or to protect land against overflow. 

Embankments that have zoned construction (core and shell) are not considered. In this 

table, the soils are rated as a source of material for embankment fill. The ratings apply to 

the soil material below the surface layer to a depth of about 5 feet. It is assumed that soil 

layers will be uniformly mixed and compacted during construction. 

The ratings do not indicate the ability of the natural soil to support an embankment. 

Soil properties to a depth even greater than the height of the embankment can affect 

performance and safety of the embankment. Generally, deeper onsite investigation is 

needed to determine these properties. 

Soil material in embankments must be resistant to seepage, piping, and erosion and 

have favorable compaction characteristics. Unfavorable features include less than 5 feet 

of suitable material and a high content of stones or boulders, organic matter, or salts or 

sodium. A high water table affects the amount of usable material. It also affects 

trafficability. 

Aquifer-fed excavated ponds are pits or dugouts that extend to a ground-water aquifer 

or to a depth below a permanent water table. Excluded are ponds that are fed only by 

surface runoff and embankment ponds that impound water 3 feet or more above the 

original surface. Excavated ponds are affected by depth to a permanent water table, 

permeability of the aquifer, and quality of the water as inferred from the salinity of the soil. 

depth to bedrock and the content of large stones affect the ease of excavation.

(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 particlesize 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,” shows estimates of the engineering 

classifications 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 across. "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 15 percent or more, 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 across 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, CL-ML. 

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 across 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
Soil Survey of Greer County, Oklahoma 

350 

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 across and 3 to 10 inches across 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 across 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 generally omitted 

in the table.

Physical Soil 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 the soil is dried at 105 degrees 

C. In the table, 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. Depending on 

soil texture, 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 bar 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, 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 has a positive effect on 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 several 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. 
Soil Survey of Greer County, Oklahoma 

378 

WEG 4L. Calcareous loam, silt loam, clay loam, and silty clay loam characterized 

by a strongly or violently effervescent reaction to cold dilute (1N) HCI. 

WEG 5. Noncalcareous loam and silt loam with less than 20 percent clay and 

sandy clay loam, sandy clay, and hemic soil material. 

WEG 6. Noncalcareous loam and silt loam with more than 20 percent clay and 

noncalcareous clay loams that are 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 analysis of several typical pedons in the survey area are 

shown in the table, “Physical Analyses 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 National Soil Suvery 

Laboratory, Lincoln, Nebraska. 

Most determinations, except 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 (6). 

Clay—(fraction less than 0.002 millimeter) pipette extraction, weight percentages 

of all material less than 2 millimeters (3A1). 

Silt—(0.002 to 0.05 millimeter fraction) pipette extraction, weight percentages of 

all material less than 2 millimeters (3A1). 

Sand—(0.05 to 2.0 millimeters fraction) weight percentages of material less than 

2 millimeters (3A1). 

Bulk density—of less than 2 millimeters 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 

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

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

Chemical Soil Properties 

The table, “Chemical Properties of the Soils,” shows estimates of some chemical 

characteristics and features that affect soil behavior. These estimates are given for 

the 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. 

Cation-exchange capacity is the total amount of extractable bases 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. The ability to retain 

cations reduces the hazard of ground-water pollution. 

Soil reaction is a measure of acidity or alkalinity. The pH of each soil 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 

fraction of the soil less than 2 millimeters in size. 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 expressed as a percent, by weight, of hydrated calcium sulfates in the 

fraction of the soil less than 20 millimeters in size. Gypsum is partially soluble in 

water. Soils that have a high content of gypsum 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 

(mmhos/cm) or decisiemens per meter (dS/m) 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 soil if used as construction material, and the 

potential of the soil to corrode metal and concrete. 

Sodium adsorption ratio (SAR) is a measure of the amount of sodium (Na) 

relative to calcium (Ca) and magnesium (Mg) in the water extract from saturated soil 

paste. It is the ratio of the Na concentration divided by the square root of one-half of 

the Ca + Mg concentration. Soils that have SAR values 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 shown in the table, 

“Chemical Analyses 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 National Soil Suvery Laboratory, Lincoln, 

Nebraska. 

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

made on soil material smaller than 2 millimeters across. 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 (6). 

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

sulfate titration (6A1c).

Water Features 

The table, “Water Features,” shows 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. 

Surface runoff refers to the loss of water from an area by flow over the land 

surface. Surface runoff classes are based on slope, climate, and vegetative cover. It 

is assumed that the surface of the soil is bare and that the retention of surface water 

resulting from irregularities in the ground surface is minimal. The classes are 

negligible, very low, low, medium, high, and very high. 

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 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). 

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 ponding is based on evidence of ponded areas as indicated 

by debries 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 shows the frequency and duration of flooding and the time of year when 

flooding is mot 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,” shows estimates of various soil features. The 

estimates are used in land use planning that involves engineering considerations. 

A restrictive layer is a nearly continuous layer that has one or more physical, 

chemical, or thermal properties that significantly impede the movement of water and 

air through the soil or that 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. 

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 to pavements and other rigid structures. 

Risk of corrosion pertains to potential soil-induced electrochemical or chemical 

action that corrodes 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 or concrete 

in installations that intersect soil boundaries or soil layers is more susceptible to 

corrosion than the steel or concrete in installations that are entirely within one kind of 

soil or within one soil layer. 

For uncoated steel, the risk of corrosion, expressed as low, moderate, or high, is 

based on soil drainage class, total acidity, electrical resistivity near field capacity, and 

electrical conductivity of the saturation extract. 

For concrete, the risk of corrosion also is expressed as low, moderate, or high. It 

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

Glossary 

Aeration, soil. The exchange of air in soil with air from the atmosphere. The air in a 

well aerated soil is similar to that in the atmosphere; the air in a poorly aerated 

soil is considerably higher in carbon dioxide and lower in oxygen. 

Aggregate, soil. Many fine particles held in a single mass or cluster. Natural soil 

aggregates, such as granules, blocks, or prisms, are called peds. Clods are 

aggregates produced by tillage or logging. 

Alkali (sodic) soil. A soil having so high a degree of alkalinity (pH 8.5 or higher) or 

so high a percentage of exchangeable sodium (15 percent or more of the total 

exchangeable bases), or both, that plant growth is restricted. 

Alluvium. Material, such as 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. 

Animal unit month (AUM). The amount of forage required by one mature cow of 

approximately 1,000 pounds weight, with or without a calf, for 1 month. Aquic 

conditions. Current soil wetness characterized by saturation, reduction, and 

redoximorphic features. 

Area reclaim (in tables). An area difficult to reclaim after the removal of soil for 

construction and other uses. Revegetation and erosion control are extremely 

difficult. 

Argillic horizon. A subsoil horizon characterized by an accumulation of illuvial clay. 

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 

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

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

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

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

Backslope. The geomorphic component that forms the steepest inclined surface and 

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. 

Bedding planes. Fine strata, less than 5 millimeters thick, in unconsolidated alluvial, 

eolian, lacustrine, or marine sediment. 

Soil Survey of Greer County, Oklahoma

443
Bedrock. The solid rock that underlies the soil and other unconsolidated material or 

that is exposed at the surface. 

Bench terrace. A raised, level or nearly level strip of earth constructed on or nearly 

on a contour, supported by a barrier of rocks or similar material, and designed to 

make the soil suitable for tillage and to prevent accelerated erosion. 

Blowout. A shallow depression from which all or most of the soil material has been 

removed by wind. A blowout has a flat or irregular floor formed by a resistant 

layer or by an accumulation of pebbles or cobbles. In some blowouts the water 

table is exposed. 

Bottom land. The normal flood plain of a stream, subject to flooding. 

Boulders. Rock fragments larger than 2 feet (60 centimeters) in diameter. 

Breaks. The steep and very steep broken land at the border of an upland summit 

that is dissected by ravines. 

Brush management. Use of mechanical, chemical, or biological methods to make 

conditions favorable for reseeding or to reduce or eliminate competition from 

woody vegetation and thus allow understory grasses and forbs to recover. Brush 

management increases forage production and thus reduces the hazard of 

erosion. It can improve the habitat for some species of wildlife. 

Butte. An isolated small mountain or hill with steep or precipitous sides and a top 

variously flat, rounded, or pointed that may be a residual mass isolated by erosion 

or an exposed volcanic neck. 

Calcareous soil. A soil containing enough calcium carbonate (commonly combined 

with magnesium carbonate) to effervesce visibly when treated with cold, dilute 

hydrochloric acid. 

Caliche. A more or less cemented deposit of calcium carbonate in soils of warmtemperate, subhumid to arid areas. Caliche occurs as soft, thin layers in the soil 

or as hard, thick beds directly beneath the solum, or it is exposed at the surface 

by erosion. 

Canyon. A long, deep, narrow, very steep-sided valley with high, precipitous walls in 

an area of high local relief. 

Capillary water. Water held as a film around soil particles and in tiny spaces 

between particles. Surface tension is the adhesive force that holds capillary water 

in the soil. 

Catena. A sequence of soils on a landscape that formed in similar kinds of parent 

material but have different characteristics as a result of differences in relief and 

drainage. 

Cation. An ion carrying a positive charge of electricity. The common soil cations are 

calcium, potassium, magnesium, sodium, and hydrogen. 

Cation-exchange capacity. The total amount of exchangeable cations that can be 

held by the soil, expressed in terms of milliequivalents per 100 grams of soil at 

neutrality (pH 7.0) or at some other stated pH value. The term, as applied to soils, 

is synonymous with base-exchange capacity but is more precise in meaning. 

Cemented. Material in an air-dry test specimen that does not slake after being 

immersed in water for 1 hour. Cemented soil material has a brittle, hard 

consistence caused by some cementing agent other than clay. Calcium 

carbonate, silica, or oxides or salts of iron and aluminum are common cementing 

materials. 

Channeled. Refers to a drainage area in which natural meandering or repeated 

branching and convergence of a streambed have created deeply incised cuts, 

either active or abandoned, in alluvial material. 

Channery soil material. Soil material that is, by volume, 15 to 35 percent thin, flat 

fragments of sandstone, shale, slate, limestone, or schist as much as 6 inches 

(15 centimeters) along the longest axis. A single piece is called a channer. 

Chemical treatment. Control of unwanted vegetation through the use of chemicals. 

Soil Survey of Greer County, Oklahoma

444
Chiseling. Tillage with an implement having one or more soil-penetrating points that 

shatter or loosen hard, compacted layers to a depth below normal plow depth. 

Clay. As a soil separate, the mineral soil particles less than 0.002 millimeter in 

diameter. As a soil textural class, soil material that is 40 percent or more clay, 

less than 45 percent sand, and less than 40 percent silt. 

Clay depletions. Low-chroma zones having a low content of iron, manganese, and 

clay because of the chemical reduction of iron and manganese and the removal 

of iron, manganese, and clay. A type of redoximorphic depletion. 

Clayey soil. Silty clay, sandy clay, or clay. 

Clay film. A thin coating of oriented clay on the surface of a soil aggregate or lining 

pores or root channels. Synonyms: clay coating, clay skin. 

Claypan. A slowly permeable soil horizon that contains much more clay than the 

horizons above it. A claypan is commonly hard when dry and plastic or stiff when 

wet. 

Climax plant community. The stabilized plant community on a particular site. The 

plant cover reproduces itself and does not change so long as the environment 

remains the same. 

Closed depression. A low area completely surrounded by higher ground and having 

no natural outlet.

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 practices include the use of green manure crops of grasses and 

legumes, proper tillage, adequate fertilization, and weed and pest control.

protect downslope areas by diverting runoff from its natural course. 

Drainage class (natural). Refers to the frequency and duration of wet periods under 

conditions similar to those under which the soil formed. Alterations of the water 

regime by human activities, either through drainage or irrigation, are not a 

consideration unless they have significantly changed the morphology of the soil. 

Seven classes of natural soil drainage are recognized— excessively drained,

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

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. The maximum rate at which water can infiltrate into a soil under 

a given set of conditions. 

Infiltration rate. The rate at which water penetrates the surface of the soil at any 

given instant, usually expressed in inches per hour. The rate can be limited by the 

infiltration capacity of the soil or the rate at which water is applied at the surface. 

Intake rate. The average rate of water entering the soil under irrigation. Most soils 

have a fast initial rate; the rate decreases with application time. Therefore, intake 

rate for design purposes is not a constant but is a variable depending on the net 

irrigation application. The rate of water intake, in inches per hour, is expressed as 

follows: 

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

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

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

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

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
