General Soil Map

The general soil map, which is a color map, shows the survey area divided into groups

of associated soils called general soil map units. This map is useful in planning the use

and management of large areas.

To find information about your area of interest, locate that area on the map, identify the

name of the map unit in the area on the color-coded map legend, then refer to the

section General Soil Map Units for a general description of the soils in your area.

Detailed Soil Maps

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. Note the number of the

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 1992. Soil names and

descriptions were approved in 1994. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 1996. This survey was mapped

utilizing survey photographic imagery of 1:24,000 and rectified to 1995 digital

orthophotography for SSURGO digitizing. This survey was made cooperatively by the

Natural Resources Conservation Service, the Oklahoma Agriculture Experiment Station,

and the Oklahoma Conservation Commission. It is part of the technical assistance

furnished to the Noble 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.

Summary of Tables
ix

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

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

also highlights limitations and hazards inherent in the soil, improvements needed to

overcome the limitations, and the impact of selected land uses on the environment.

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

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

needed for maximum food and fiber production. Planners, community officials, engineers, developers, builders, and home buyers can use the survey to plan land use,

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

performance. Conservationists, teachers, students, and specialists in recreation, wildlife

management, waste disposal, and pollution control can use the survey to help them

understand, protect, and enhance the environment.

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

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

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

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

very limited for basements or underground installations.

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

survey. Broad areas of soils are shown on the general soil map. The location of each

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

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

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

Conservation Service or the Cooperative Extension Service.

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

475,475 acres, or about 742 square miles. The population of the county is 11,388.

Perry, the county seat, is in the southwestern part of the county and has a population

of about 5,230. Lake McMurtry, Sooner Lake, the Arkansas River, and other water

areas of more than 40 acres in size make up about 5,400 acres. Noble County is

bordered on the north by Kay and Osage Counties, on the east by Pawnee County, on

the west by Garfield County, and on the south by Logan and Payne Counties.

This soil survey updates the survey of Noble County published in 1956 (9). It

provides additional information and has maps on a photographic background.

General Nature of the Survey Area

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

history, physiography and drainage, natural resources, and climate.

History

Noble County is located in the part of Oklahoma known as the Cherokee Outlet or

“Cherokee Strip.” In the 1800’s, cattlemen leased the area from the Cherokee Tribe and

used the land to fatten cattle from Texas before moving them to railheads in Kansas.

The West Shawnee Trail went through Noble County from Boggy Depot in Atoka County,

Oklahoma, to Wichita, Kansas. Part of the strip was opened to settlers at noon on

September 16, 1893. This was one of a series of “runs” that opened “unassigned lands”

to white settlement. The Ponca Tribe and the Otoe-Missouri Tribe retained land in the

northern part of the survey area.

As the survey area was settled, the land gradually changed from lush bluestem

prairies to areas of cultivated crops. Alfalfa, corn, cotton, and small grains were the

major crops of the early settlers. Today, wheat is the main crop.

Physiography and Drainage

Noble County is within the Central Rolling Red Prairies Major Land Resource Area

(MLRA 80A) and the Cross Timbers Major Land Resource Area (MLRA 84A). Most of

the county drains eastward into the Arkansas River. The southern one-fourth of the

county is drained by Stillwater Creek, which drains southeastward into the Cimarron

River. The Arkansas River and the Salt Fork of the Arkansas River border the

northeastern corner of the county. Black Bear Creek and Red Rock Creek drain the

western and eastern parts of the county. Major flooding occurs along Black Bear Creek,

Red Rock Creek, the Salt Fork of the Arkansas River, and the Arkansas River.

The relief in Noble County is dominantly gently undulating to steep uplands. The

northern half of the county has a large area of nearly level to gently undulating uplands,

and the southern half of the county dominantly has undulating to steep uplands.

Elevation ranges from 840 feet, in the Arkansas River Valley in the northeastern part of

the county, to 1,270 feet, in the southwestern part of the county.

Natural Resources

The mineral and water resources of Noble County are important to the overall

development and progress of the county. Petroleum production is by far the most

important mineral activity. In 1993, petroleum production in Noble County amounted to

about 1.7 million barrels of crude oil (valued at $28.5 million) and about 5 billion cubic

feet of natural gas (valued at $9.6 million). Due to these production levels, Noble

County ranks near the middle of the petroleum-producing counties in Oklahoma.

Sand and gravel have been produced from a number of sites in the alluvial and

terrace deposits of the county, and thin beds of limestone and sandstone have been

quarried at several sites for the construction of highways and county roads. In addition,

a number of small deposits of copper minerals occur at scattered locations in the

county, although these deposits are not commercially mined at this time.

Small or moderate quantities of good-quality ground water occur in some of the

Quaternary alluvial and terrace deposits and are locally available from thin sandstone

beds in the Wellington Formation. A number of wells in Noble County yield 5 to 30

gallons of water per minute. There are also a large number of test wells, which do not

yield even enough water for household use (3, 8).

Climate

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

for the survey area as recorded at Billings, Oklahoma, 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 36.2 degrees F and the average daily minimum

temperature is 25.4 degrees. The lowest temperature on record, which occurred at

Billings on January 8, 1988, was -15 degrees. In summer, the average temperature is

80.0 degrees and the average daily maximum temperature is 91.8 degrees. The highest

recorded temperature, which occurred at Billings on July 7, 1996, was 113 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 35.75 inches. Of this, 25.7 inches, or about

72 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 7.88

inches, which occurred at Billings on October 3, 1986. Thunderstorms occur on about

50 days each year, and most occur between May and August.

The average seasonal snowfall is 9.1 inches. The greatest snow depth at any one

time during the period of record was 12 inches, which was recorded on March 14, 1999.

On an average, 5 days per year have at least 1 inch of snow on the ground. The

heaviest 1-day snowfall on record was 14.2 inches, which was recorded on March 14,

1999.

The average relative humidity in mid-afternoon is about 52 percent. Humidity is

higher at night, and the average at dawn is about 80 percent. The sun shines 78

percent of the time possible in summer and 60 percent in winter. The prevailing wind is

from the south. Average windspeed is highest, around 14 miles per hour, in March and

April.

6 Soil Survey

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 (13). After describing the soils in the survey area and determining their

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

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

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

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

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

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

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

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

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

research.

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

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

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

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

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

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

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

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

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

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

field or plot experiments on the same kinds of soil.

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

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

long periods of time, but they are not predictable from year to year. For example, soil

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

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

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

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

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

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

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

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

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

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

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

The general soil map shows broad areas that have a distinctive pattern of soils,

relief, and drainage. Each map unit on the general soil map is a unique natural

landscape. Typically, it consists of one or more major soils or miscellaneous areas and

some minor soils or miscellaneous areas. It is named for the major soils or

miscellaneous areas. The soils or miscellaneous areas making up one unit can occur

in another but in a different pattern.

The general soil map is part of the State Soil Geographic Data Base (STATSGO). It

is at a scale of 1 to 250,000. It should not be used to locate soils for intensive land

uses, such as determining the suitability of a soil for house lots. It is useful for

understanding the soil resource and for planning broad land uses in a State or region.

The component composition of a STATSGO map unit does not statistically represent a

subset (county) or any one portion of the whole STATSGO map unit. A STATSGO map

unit may have up to 21 named components, but any one particular area within the

STATSGO map unit may not consist of all named components or the components of

the entire STATSGO map unit.

The general soil map reflects the STATSGO composition of the county subset. The

subset name of a general soil map unit may vary from county to county, but it is within

the parameters of the entire STATSGO map unit. In the legend for the general soil

map, the STATSGO map unit name is listed first and the county general soil map unit

name is listed (in parentheses) directly after the STATSGO name. The STATSGO

reference number (which consists of the letters “OK” followed by a three-digit number)

precedes the STATSGO name.

The general soil map can be used to compare the suitability of large areas for

general land uses. Areas of suitable soils or miscellaneous areas can be identified on

the map. Likewise, areas that are not suitable can be identified.

Because of its small scale, the map is not suitable for planning the management of

a farm or field or for selecting a site for a road or building or other structure. The soils

in any one map unit differ from place to place in slope, depth, drainage, and other

characteristics that affect management.

The map units on the detailed soil maps represent the soils or miscellaneous areas in

the survey area. The map unit descriptions in this section, along with the maps, can be

used to determine the suitability and potential of a unit for specific uses. They also can

be used to plan the management needed for those uses. More information about each

map unit is given in the section “Use and Management of the Soils.”

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

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

named according to the taxonomic classification of the dominant soils or miscellaneous

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

the soils. On the landscape, however, the soils and miscellaneous areas are natural

phenomena, and they have the characteristic variability of all natural phenomena. Thus,

the range of some observed properties may extend beyond the limits defined for a

taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, are mapped

without areas of minor components of other taxonomic classes. Consequently, map

units are made up of the soils or miscellaneous areas for which they are named and

some areas of included soils that belong to other taxonomic classes.

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

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

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

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

behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, inclusions. They generally are in small

areas and could not be mapped separately because of the scale used. Some small

areas of strongly contrasting soils or miscellaneous areas are identified by a special

symbol on the maps. The included areas of contrasting soils or miscellaneous areas are

mentioned in the map unit descriptions. A few included areas may not have been

observed, and consequently they are not mentioned in the descriptions, especially

where the pattern was so complex that it was impractical to make enough observations

to identify all the soils and miscellaneous areas on the landscape.

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

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

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

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

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

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

soils and miscellaneous areas.

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

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

limitations to be considered in planning for specific uses.

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

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

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

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

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

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

Detailed Soil Map Units
30 Soil Survey

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, Ashport silt loam, 0 to 1 percent slopes,

occasionally flooded, is a phase of the Ashport series.

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

These map units are complexes or undifferentiated groups.

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

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

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

areas. Newalla-Darnell complex, 8 to 45 percent slopes, very bouldery, is an example.

An undifferentiated group consists of two or more soils or miscellaneous areas that

are not consistently associated geographically and, therefore, do not always occur

together in the same map delineation. These components are included in the same

named map unit because their use and management are the same or very similar for

common uses. Generally, they are grouped together because some common feature

determines their use and management. Each delineation has at least one of the major

components, and some may have all of them. Coyle and Zaneis soils, 3 to 5 percent

slopes, severely eroded, is an example.

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

and support little or no vegetation. The Urban land part of Norge-Urban land complex, 1

to 5 percent slopes, is an example.

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

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

properties of the soils and the limitations, capabilities, and potentials for many uses.

The Glossary defines many of the terms used in describing the soils or miscellaneous

areas.

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

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

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

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

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

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

various soil uses and management. Field experience and collected data on soil properties and performance are used as a basis in predicting soil behavior.

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

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

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

and for wildlife habitat. It can be used to identify the potentials and limitations of each

soil for specific land uses and to help prevent construction failures caused by unfavorable soil properties.

Interpretive ratings help engineers, planners, and others understand how soil properties influence important nonagricultural uses, such as building site development and

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

the suitability of the soils for these uses.

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

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

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

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

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

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

costs of site preparation and maintenance.

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

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

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

natural soil.

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

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

can cause difficulty in excavation.

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

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

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

Agronomy

General management concerns affecting the production of crops and hay and pasture

plants 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

specific information available from the local office of the Natural Resources

Conservation Service or the Cooperative Extension Service.

Use and Management of the Soils
148 Soil Survey

Land Capability Classification

Land capability classification shows, in a general way, the suitability of soils for most

kinds of field crops. Crops that require special management are excluded. The soils are

grouped according to their limitations for field crops, the risk of damage if they are used

for crops, and the way they respond to management. The criteria used in grouping the

soils do not include major and generally expensive landforming that would change slope,

depth, or other characteristics of the soils, nor do they include possible but unlikely

major reclamation projects. Capability classification is not a substitute for interpretations

designed to show suitability and limitations of groups of soils for rangeland, woodland, or

engineering purposes.

In the capability system, soils generally are grouped at three levels: capability class,

subclass, and unit (14). These levels indicate the degree and kinds of limitations

affecting mechanized farming systems that produce the more commonly grown field

crops, such as corn, small grain, cotton, hay, and field-grown vegetables. Only class

and subclass are used in this survey.

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

8. The numerals indicate progressively greater limitations and narrower choices for

practical use.

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

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

the soil limitations affecting the production of cultivated crops increases progressively

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

permanent soil deterioration caused by erosion and other factors.

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

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

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

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

office of the Natural Resources Conservation Service or the Cooperative Extension

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

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

These areas may have potential for other uses, such as recreational facilities and

wildlife habitat.

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

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

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

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

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

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

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

limitation is climate that is very cold or very dry.

There are no subclasses in class 1 because the soils of this class have few limitations. Class 5 contains only the subclasses indicated by w, s, or c because the soils in

class 5 are subject to little or no erosion. They have other limitations that restrict their

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

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

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

Pasture” and in the “Detailed Soil Map Units” section.

Land Capability and Yields per Acre of Crops

(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)

Estimated Yields of Crops, Hay, and Pasture

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

level of management are shown in the 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 yields are based mainly on the experience and records of farmers, conservationists, and extension agents. Available yield data from nearby counties and results of field

trials and demonstrations are also considered.

The management needed to obtain the indicated yields of the various crops depends

on the kind of soil and the crop. Management can include drainage, erosion control, and

protection from flooding; the proper planting and seeding rates; suitable high-yielding

crop varieties; appropriate and timely tillage; control of weeds, plant diseases, and

harmful insects; favorable soil reaction and optimum levels of nitrogen, phosphorus,

potassium, and trace elements for each crop; effective use of crop residue, barnyard

manure, and green manure crops; and harvesting that ensures the smallest possible

loss.

The estimated yields reflect the productive capacity of each soil for each of the

principal crops. Yields are likely to increase as new production technology is developed.

The productivity of a given soil compared with that of other soils, however, is not likely

to change.

Crops other than those shown in the tables are grown in the survey area, but estimated yields are not listed because the acreage of such crops is small.

Under good pasture management, proper grazing is essential for the production of

high-quality forage, stand survival, and erosion control. Proper grazing helps plants to

maintain sufficient and generally vigorous top growth during the growing season. Brush

control is essential in many areas, and weed control generally is needed. Rotation

grazing and renovation also are important management practices.

A pasture program is needed to provide the desired amount of forage during each

month of the year. A study of the growth habits of the different plants is necessary to

ensure adequate forage during each month. The months that various kinds of forage

plants grow are indicated in figure 22, which is in the “Range” section. The percent

growth that can be safely grazed each month without substantially reducing the total

yield for each kind of plant is illustrated.

Yield estimates are often indicated in animal unit months (AUM), or the amount of

forage or feed required to feed one animal unit (one cow, one horse, one mule, five

sheep, or five goats) for 30 days.

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

Extension Service can provide information about forage yields other than those shown in

the tables.

Cropland Limitations and Hazards

The management concerns affecting the use of the detailed map units in the survey

area for crops are shown in the table “Cropland Limitations and Hazards.” The main

concerns in managing nonirrigated cropland are conserving moisture, controlling soil

blowing and water erosion, and maintaining soil fertility and tilth.

Conserving moisture primarily involves reducing the evaporation and runoff rates and

increasing the rate of water infiltration. Applying conservation tillage and conservation

cropping systems, farming on the contour, stripcropping, establishing field windbreaks,

and leaving crop residue on the surface conserve moisture.

Generally, a combination of several practices is needed to control soil blowing and

water erosion. Conservation tillage, stripcropping, field windbreaks, tall grass barriers,
162 Soil Survey

contour farming, conservation cropping systems, crop residue management, diversions,

and grassed waterways help to prevent excessive soil loss.

Measures that are effective in maintaining soil fertility include applying fertilizer, both

organic and inorganic, including manure; incorporating crop residue or green manure

crops into the soil; and using proper crop rotations. Controlling erosion helps to prevent

the loss of organic matter and plant nutrients and thus helps to maintain productivity,

although the level of fertility can be reduced even in areas where erosion is controlled.

All soils used for nonirrigated crops respond well to applications of fertilizer.

On irrigated soils the main management concerns are efficient water use, nutrient

management, control of erosion, soil tilth, pest and weed control, and timely planting

and harvesting for a successful crop. An irrigation system that provides optimum control

and distribution of water at minimum cost is needed. Overirrigation wastes water,

leaches plant nutrients, and causes erosion. Also, it can create drainage problems, raise

the water table, and increase soil salinity.

Some of the limitations and hazards shown in the table cannot be easily overcome.

These are flooding, depth to bedrock, and ponding.

Additional limitations and hazards are as follows:

Areas of rock outcrop and oil waste land.—Farming around these areas may be

feasible. Subsoiling or deep ripping soft sedimentary beds increases the effective

rooting depth and the rate of water infiltration.

Excessive permeability.—This limitation causes deep leaching of nutrients and

pesticides. The capacity of the soil to retain moisture for plant use is poor.

Potential for ground-water pollution.—This is a hazard in soils with excessive permeability, hard bedrock, or a water table within the profile.

Lime content, limited available water capacity, poor tilth, restricted permeability, and

surface crusting.—The adverse effects of these limitations can be reduced by incorporating green manure crops, manure, or crop residue into the soil; applying a system of

conservation tillage; and using conservation cropping systems. Also, crops may respond

well to additions of phosphate fertilizer on soils that have a high content of lime.

Slope.—Where the slope is more than 8 percent, water erosion and soil blowing may

be accelerated unless conservation farming practices are applied.

Salt and sodium content.—In areas where this is a limitation, only salt- and sodiumtolerant crops should be grown.

Criteria for Limitations and Hazards

Following is an explanation of the criteria used to determine the limitations or hazards.

Areas of rock outcrop.—Rock outcrop is a named component of the map unit.

Areas of oil waste land.—Oil waste land is a named component of the map unit.

Depth to bedrock.—Bedrock is within a depth of 40 inches.

Water erosion.—The surface K factor multiplied by the upper slope limit is more

than 2 (same as prime farmland criteria).

Excessive permeability.—The upper limit of the permeability range is 6 inches or

more within the soil profile.

Flooding.—The component of the map unit is occasionally flooded or frequently

flooded.

Lime content.—The upper 10 inches has more than 15 percent calcium carbonate

equivalent.

Limited available water capacity.—The available water capacity calculated to a depth

of 60 inches or to a root-limiting layer is 6 inches or less.

Ponding.—A ponding duration is assigned to the component of the map unit.

Potential for ground-water pollution.—The soil has a water table within a depth of 4

feet or bedrock within 40 inches of the surface, or permeability is more than 2 inches per

Prime Farmland

Prime farmland is of major importance in meeting the Nation’s short- and long-range

needs for food and fiber. The acreage of high-quality farmland is limited, and the U.S.

Department of Agriculture recognizes that government at local, State, and Federal

levels, as well as individuals, must encourage and facilitate the wise use of our Nation’s

prime farmland.

Prime farmland soils, as defined by the U.S. Department of Agriculture, are soils that

are best suited to food, feed, forage, fiber, and oilseed crops. Such soils have properties

that favor the economic production of sustained high yields of crops. The soils need only

to be treated and managed by acceptable farming methods. An adequate moisture

supply and a sufficiently long growing season are required. Prime farmland soils produce

the highest yields with minimal expenditure of energy and economic resources, and

farming these soils results in the least damage to the environment.

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 199,342 acres in the survey area, or nearly 42 percent of the total acreage,

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.” The table does

not constitute a recommendation for a particular land use.

Range

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

section.

Range, grazed forestland, and native pasture provide forage for livestock in the

survey area.

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

potential, plant community) is predominantly grasses, grass-like plants, forbs, and

shrubs suitable for grazing and browsing. Range includes natural grasslands,

savannahs, many wetlands, some deserts, tundra, and certain shrub and forb communities. Range receives no regular or frequent cultural treatment. The composition and

production of the plant community are determined by soil, climate, topography, overstory

canopy, and grazing management.

Grazed forestland is defined as land on which the understory includes, as an integral

part of the forest plant community, plants that can be grazed without significant impairment of other forest values.

Native pasture is defined as land on which the potential (climax) vegetation is forest

but which is used and managed primarily for the production of native forage plants.

Native pasture includes cutover forestland and forestland that has been cleared and is

managed for native or naturalized forage plants.

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 in the rangeland composition.

Rangeland makes up about 40 percent of Noble County. It is mainly on gently sloping

to steep side slopes and on a few narrow very gently sloping to sloping summits that

cannot be economically cultivated. A few native grass meadows that are managed for

hay production are in the central and north-central parts of the county.

Noble County has three types of range. The first type is in the southeastern part of

the county, in areas where most of the soils are loamy and are moderately deep or

shallow over sandstone. These soils support an oak savannah that has low productivity

due to the shallow rooting depth and low water-holding capacity.

The second type is in the northeastern and western parts of the county, in areas

where the soils are loamy and are dominantly moderately deep, with some shallow or

deep soils, over shale and shale interbedded with sandstone. These soils support mid

and tall grasses, and productivity is moderate.

The third type is in the north-central, central, and south-central parts of the county, in

areas where the soils are loamy and are moderately deep, with some shallow and deep

soils, over sandstone and sandstone interbedded with shale. The soils support tall and

mid grasses that are moderately productive.

Approximately 75 percent of the annual production on rangeland grows in April, May,

and June, responding to spring rains and moderate temperatures. A secondary growth

period generally occurs in September and October, coinciding with fall rains and cooling

temperatures.

Most of the local ranches and livestock farms are cow-calf operations. There are

some pure stocker enterprises and some ranchers that diversify their cow-calf operation

with stockers in order to provide greater flexibility.

Several livestock operations supplement the grazing of native rangeland with introduced grasses such as bermudagrass and plains bluestem. Forage crops are also used.

Protein, hay, and small grain crops are used to supplement livestock through winter.

Droughts occur in varying lengths. Short-term summer droughts are common, and

longer periods of drought, some lasting several months, also occur frequently.

The pre-settlement vegetation evolved according to periodic natural fires, droughts,
176 Soil Survey

migratory grazing by bison, and the impact from many other wildlife species. The bison

heavily impacted an area and then moved to other grazing range.

Early settlement brought continuous grazing and eliminated much of the high-quality

vegetation on some range sites. Areas that were once open savannah range sites with a

mixture of grasses, forbs, and scattered trees are now covered with oak, a few tall and

mid grasses, and low successional grasses and forbs. Some prairie sites are now

producing low successional grasses and forbs instead of tall grasses. The amount of

forage currently produced may be less than half of that originally produced. Eastern

redcedar has increased significantly on some sites due to the lack of prairie fires.

Remnants of the original plant species, however, are still found on most rangeland.

Progressive grazing management can allow these high-quality plants to reestablish

without reseeding.

An ecological site is a distinctive kind of land with specific physical characteristics

that make it different from other sites in its ability to produce a distinctive kind and

amount of vegetation.

Many different ecological sites are in the survey area. Over time, a combination of

plants best suited to a particular soil and climate becomes dominant. If the soil is not

excessively disturbed, this group of plants is the natural plant community for the site.

Natural plant communities are not static but vary slightly from year to year and place to

place.

The relationship between soils and vegetation was ascertained during this survey;

thus, ecological sites generally can be determined directly from the soil map. Soil

properties that affect moisture supply and plant nutrients have the greatest influence on

the productivity of range plants. Soil reaction, salt content, and a seasonal high water

table are also important. The “Field Office Technical Guide,” which is available at the

local office of the Natural Resources Conservation Service, can provide specific information about ecological sites.

Total dry-weight production is the amount of vegetation that can be expected to grow

annually on well managed rangeland. It includes all vegetation, whether or not it is

palatable to grazing animals. It includes the current year’s growth of leaves, twigs, and

fruit of woody plants. It does not include the increase in stem diameter of trees and

shrubs. It is expressed in pounds per acre of air-dry vegetation for favorable, normal,

and unfavorable years. In a favorable year, the amount and distribution of precipitation

and the temperatures make growing conditions substantially better than average. In a

normal year, growing conditions are near the historical monthly average. In an unfavorable year, growing conditions are well below average, generally because of low available

soil moisture. Figure 22 shows a typical growth curve for native vegetation and other

forage that represents the percentage of total growth that occurs each month.

Dry weight is the total annual yield per acre of air-dry vegetation. Yields are adjusted

to a percent of air-dry moisture content. The relationship of green weight to air-dry weight

varies according to such factors as stage of maturity, exposure, amount of shade,

recent rains, and unseasonable dry periods.

Characteristic vegetation consists of the grasses, forbs, and shrubs that make up

most of the potential natural plant community on each soil. The plants are listed by

common name. Under composition, the anticipated percentage of the total annual

production is given for each species making up the characteristic vegetation. The

amount that can be used as forage depends on the kinds of grazing animals and on the

grazing season.

Similarity Index

Similarity index indicates, by percentages ranging from 1 to 100, the extent to which

the present plant community resembles one of two other plant communities on an

ecological site. A similarity index can be used to compare the present vegetation on an
Noble County, Oklahoma 177

ecological site to the presumed historic vegetation for that site. This comparison provides a basis for ascertaining the extent and direction of changes that have differentiated the current vegetation from the historic vegetation. A similarity index of 70 would

suggest that the present plant community has 70 percent of the presumed historic plant

community for the site.

The management goal is not necessarily a present plant community that has as

similarity index of 100 when compared to the historic plant community. A similarity index

can be used as a measure of how near the current plant community is to the goal of the

landowner, that is, the percentage of the present plant community that resembles a

desired plant community.

Abnormal disturbances that change the natural plant community include repeated

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

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

grazed at a severity that does not allow for recovery. A very severe disturbance can

completely destroy the natural community. Under these conditions, the less desirable

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

the soils have not deteriorated significantly, the plant community eventually can return

to predominantly natural plants if proper range management is applied.

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

the management needed to maintain or improve the desired plant community for selected uses. Such information is needed to support or maintain management objectives,

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

recreational uses, and the condition of watersheds.

Rangeland Management

Rangeland management requires a knowledge of the kinds of soil and of the potential

natural plant community. It also requires an evaluation of the similarity index.

Effective range management conserves rainfall, enhances water quality, reduces the

hazard of downstream flooding, improves yields, provides forage for livestock and

Figure 22.—Typical growth curves for various kinds of forage in Noble County. The

growth curve for each kind of forage indicates the percentage of the total annual

growth that occurs each month.
178 Soil Survey

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 take place gradually and may be overlooked.

Each range manager should evaluate the type of plant community that best supports

the ranch and then apply management and ecological principles to achieve the goals.

The desired plant community should be within the capabilities of the land.

The primary range management practices used in Noble County include prescribed

grazing, stock-water developments, and fences. If undesirable plants become dominant,

range seeding, brush management, or prescribed burning are commonly used.

Range management includes four major considerations:

1. Proper grazing distribution, which is achieved by managing livestock so that all

parts of the grazing unit are grazed equally.

2. Selective grazing, which occurs because animals graze preferred plants to

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

damaged.

3. A proper stocking rate, which is achieved by balancing animal numbers with

forage production.

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

maintain their growth.

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

composition is determined by grazing management.

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

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

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

of plants, about 50 percent of the annual growth of the key or most important grazing

plants should remain at the end of the grazing season. Plants can be removed not only

through grazing by livestock but also through grazing by rodents, insects, and wildlife

and through the deterioration caused by climatic variations. Because of these factors, a

safe initial stocking rate for livestock should be calculated on the basis of 25 percent of

the total annual growth, by weight, of the vegetation.

For example, production could be 3,500 pounds per acre of air-dry grasses, forbs,

and limited woody species during an average season on a Loamy Prairie ecological site

where the similarity between the present plant community and the historic plant community is more than 70 percent. Twenty-five percent of this production is 875 pounds per

acre.

A 1,000-pound cow and her calf is equivalent to one animal unit (AU) and will consume about 2.6 percent of her body weight (26 pounds) of forage per day. So, in one

month, an animal unit will consume 790 pounds of native vegetation, depending on the

quality and stage of growth of the plants (26 pounds per day times 365 days per year

divided by 12 months per year).

Dividing 875 pounds (forage allocation) by 26 pounds (forage required per day for one

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

of 70 will feed one cow for 33.6 days. To convert forage available from 1 acre to an

animal unit month (AUM), the available forage (875 pounds) is divided by the amount

required to feed an animal unit for 1 month (790 pounds). One acre will provide 1.1 AUM

of grazing. Therefore, 10.9 acres will feed one cow for 12 months in this example.

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

per month times 12 months equals 9,490 pounds). Dividing the 875 pounds of usable

forage per acre into the 9,490 pounds needed by the cow reveals that approximately

10.9 acres is needed for one cow annually. Stocking rate calculation should be adjusted

for animal size, grazing system, and grazing season.

Ecological Sites

Twenty-five ecological sites are recognized in Noble County. The ecological site

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

characters identify the major land resource area, the sixth character identifies the major

land resource unit subdivision, the next three characters identify the individual ecological site number, and the final two characters identify the state. The ecological site

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

describe the ecological sites in Noble County and list the plants that are characteristic

of each site. Detailed ecological site descriptions are available at the local office of the

Natural Resources Conservation Service.

R080AY010OK, Claypan Prairie (north).—This site is in areas of nearly level to

gently sloping, deep and very deep, loamy soils. These soils have a dense clayey

subsoil that absorbs water slowly and restricts root penetration. Under good management, the important plants are little bluestem, switchgrass, leadplant, and perennial

sunflowers. As the site deteriorates, sideoats grama, blue grama, tall dropseed, wild

alfalfa, and buckbrush increase in abundance. Forage production is moderate.

R080AY014OK, Deep Sand.—This site is in areas of nearly level to sloping, very

deep, sandy soils. Forage production is moderate. Areas consist of rolling hills separated by narrow valleys. Under good management, the important plants are sand

bluestem, indiangrass, switchgrass, little bluestem, and sand lovegrass. As the site

deteriorates, tall dropseed, blue grama, sandbur, prairie sagewort, skunkbush, and sand

plum increase in abundance.

R080AY022OK, Dune.—This site is in areas of very deep, strongly sloping to steep,

sandy soils. Forage production is low. Areas consist of choppy high dunes separated by

narrow valleys. Careful grazing management is needed to prevent the development of

blowout areas. Under good management, the important plants are sand bluestem, little

bluestem, giant sandreed, and sand lovegrass. If this site is abused, Texas bluegrass,

sand paspalum, sandlily, bush morningglory, and skunkbush increase in abundance.

R080AY045OK, Heavy Bottomland.—This site is in areas of nearly level, very gently

sloping, very deep, clayey soils on flood plains. These soils absorb water slowly. Large

cracks are common during droughty periods. Under good management, the important

plants are big bluestem, indiangrass, prairie cordgrass, switchgrass, and perennial

sunflowers. If abused, tall dropseed, goldenrods, sedges, and persimmon increase in

abundance. Forage production is moderate.

R080AY050OK, Loamy Bottomland.—This site is in areas of nearly level to sloping,

very deep, loamy soils on flood plains or terraces. Forage production is high. Under good

management, the important plants are big bluestem, indiangrass, eastern gamagrass,

compassplant, and switchgrass. It this site is abused, beaked panicum, tall dropseed,

heath aster, sedges, elm, and greenbrier increase in abundance.

R080AY056OK, Loamy Prairie.—This site is in areas where the climax vegetation is

primarily little bluestem, big bluestem, indiangrass, and switchgrass. These plants,

together with Canada wildrye, make up about 70 percent of the vegetation. Under

continuous heavy grazing, the principal grasses are sideoats grama and blue grama.

Leadplant, wildindigo, scurfpea, and prairie acacia are the common legumes.

R080AY068OK, Sandy Bottomland.—This site is in areas of nearly level, very

gently sloping, very deep, sandy soils on flood plains or terraces. These soils are

droughty and subject to soil blowing. Forage production is low. Under good management,

the important plants are switchgrass, sand bluestem, indiangrass, and perennial sunflowers. If this site is abused, beaked panicum, Texas bluegrass, goldenrods, willow, and

cottonwood increase in abundance.

R080AY073OK, Sandy Prairie.—This site is in areas of very gently sloping to

undulating, deep, moderately sandy soils on uplands. Forage production is high. The

soils have a moderate water-holding capacity, which benefits root development and
180 Soil Survey

moisture storage. Under good management, the important plants are sand bluestem,

little bluestem, and indiangrass. If this site is subject to continual heavy grazing,

sideoats grama, blue grama, and sand dropseed increase in abundance.

R080AY080OK, Shallow Clay Prairie.—This site is in areas of severely eroded,

gently sloping to strongly sloping, shallow, raw, clayey soils that are underlain by shale.

The shale is commonly exposed on the steeper slopes. Vegetation is difficult to establish. Under good management, the important plants are sideoats grama, little bluestem,

and hairy grama. It this site is subject to continual heavy grazing, grass cover is

reduced and areas of bare soil increase. Carefully managed grazing can prevent erosion.

Forage production is very low. This site has some natural erosion.

R080AY083OK, Shallow Prairie.—This site is in areas where the potential plant

community is tall grasses. Species composition, by weight, is 75 percent grasses, 20

percent forbs, and 5 percent woody plants. Big bluestem, indiangrass, switchgrass, little

bluestem, tephrosia, catclaw sensitivebrier, perennial sunflowers, and skunkbush are

preferred plants and make up 65 percent of livestock forage when the site is in excellent

condition. If the site is subject to continuous heavy grazing, these plants are replaced

by less palatable plants, such as dropseeds, jointtail, Scribner panicum, buffalograss,

wildindigo, milkweeds, sagewort, sumacs, and indigobush. As the site deteriorates,

other plants, such as broomsedge bluestem, splitbeard, Japanese brome, showy

partridgepea, common broomweed, ragweeds, bitter sneezeweed, crotons, persimmon,

and hawthorn, dominate the site.

R080AY090OK, Meadow.—This site is in areas where the vegetation includes

grasses, sedges, rushes, buttonbush, and various broadleaf plants. Willow and cottonwood trees are common. In these areas, water is ponded for long or very long periods

but the areas typically do not have standing water during the growing season. For a

considerable part of the year, the water table is within a depth of a few inches.

R080AY091OK, Slickspot.—This site is in areas of gently sloping, deep and very

deep, loamy soils on uplands. These soils have a clayey, alkali subsoil with blocky

structure. Forage production is low because of a slow rate of water intake, salt content,

and poor aeration. Under good management, the important plants, which are alkali

sacaton, switchgrass, western wheatgrass, tall dropseed, white tridens, and blue grama,

make up 50 percent of the vegetation. Other plants include dotted gayfeather, whorled

dropseed, gummy lovegrass, fall witchgrass, yellow neptunia, mourning lovegrass,

purple threeawn, curlycup gumweed, goldenweed, and hairy goldaster. If the site is

abused, blue grama, silver bluestem, wild alfalfa, lanceleaf ragweed, threeawn, and

western ragweed increase in abundance.

R080AY095OK, Subirrigated.—This site is in areas of deep, nearly level, very gently

sloping, sandy soils on uplands or flood plains. These soils have a high water table,

which is beneficial to plant growth. Forage production is high. Under good management,

the important plants are switchgrass, big bluestem, indiangrass, and eastern

gamagrass. If the site is abused, tall dropseed, sideoats grama, sedges, willow, and

cottonwood increase in abundance.

R080AY099OK, Depressional Upland.—This site is in areas where, depending upon

the degree of inundation, the dominant plants are willow, switchgrass, prairie cordgrass,

indiangrass, cattails, western wheatgrass, sedges, bristlegrass, Illinois bundleflower,

duckweed, sedges, and other forbs.

R080AY810OK, Reseeded Claypan Prairie.—This site is in areas of formerly

cultivated land that typically are seeded to sideoats grama, blue grama, little bluestem,

sand bluestem, and indiangrass. The site may have been damaged by erosion, and soil

fertility is inherently low. If the site is abused, broomweeds and threeawn dominate.

R080AY856OK, Reseeded Loamy Prairie.—This site is in areas where the plant

cover includes big bluestem, switchgrass, little bluestem, indiangrass, and other seeded

species. Native legumes can be abundant. Other important grasses include jointtail,
Noble County, Oklahoma 181

meadow dropseed, tall dropseed, and hairy grama. Production is much lower than the

Loamy Prairie ecological site due to a lower quality of soil health.

R080AY880OK, Reseeded Clay.—This site is in areas of severely eroded, deep,

loamy, upland soils that were formerly cultivated and have a clay subsoil. When reseeded and well managed, this site can support little bluestem, big bluestem,

indiangrass, switchgrass, and sideoats grama. If the site is abused, annual threeawn,

western ragweed, blue grama, buffalograss, and common broomweed dominate. Carefully managing grazing can prevent erosion. Forage production is very low.

R080AY883OK, Reseeded Shallow Prairie.—This site is in areas where the seeded

grasses include sideoats grama and native bluestem mixes. If the site is heavily grazed,

the dominant plants are hairy grama, buffalograss, dropseed, silver bluestem,

cheatgrass, broomweed, western ragweed, and other weedy grasses and forbs. Because

of past use and erosion, this site is not productive.

R084AY018OK, Deep Sand Savannah.—This site is in areas of very gently sloping

to moderately steep, very deep, sandy soils on uplands. Under good management, the

important plants consist of an overstory of post oak and blackjack oak and an understory of big bluestem, sand lovegrass, and switchgrass. The trees occur in thick stands

or in scattered stands. As trees thicken, herbaceous vegetation decreases in abundance. If the site is abused, tall dropseed, purpletop, Scribner panicum, heathaster,

white snakeroot, splitbeard bluestem, broomsedge bluestem, winged elm, hickory,

buckbrush, sumac, and shrubby oak increase in abundance. Eastern redcedar can

increase in abundance if the site is not subject to fires.

R084AY050OK, Loamy Bottomland.—This site is in areas where the pristine plant

community is tall grasses. Species composition, by weight, is 70 percent grasses, 20

percent forbs, and 10 percent woody plants. Eastern gamagrass, Florida paspalum,

prairie cordgrass, big bluestem, indiangrass, switchgrass, switchcane, leadplant, Illinois

bundleflower, compassplant, gayfeather, and passion vine are the major plants and

make up 75 percent of the production when the site is in top ecological condition. If the

site is heavily grazed, these plants are replaced by such plants as little bluestem, tall

dropseed, Scribner panicum, sedges, rushes, wildindigo, perennial sunflowers, goldenrods, trumpetvine, winged elm, sumacs, and indigobush. As the site deteriorates,

unpalatable plants, such as silver bluestem, splitbeard bluestem, broomsedge bluestem,

sideoats grama, Japanese brome, threeawns, showy partridgepea, ragweeds, bitter

sneezeweed, ironweed, white snakeroot, persimmon, hawthorn, post oak, and blackjack

oak, dominate.

R084AY076OK, Sandy Savannah (central).—This site is in areas where the

decreaser grasses are little bluestem, indiangrass, big bluestem, and switchgrass.

These grasses make up at least 45 percent of the total vegetation. Canada wildrye,

Virginia wildrye, Texas bluegrass, and flatsedge are cool-season species. Woody

species include post oak, blackjack oak, hickory, ash, elm, bumelia, coralberry,

persimmon, poison ivy, grape, and hackberry. These species should not exceed 20

percent of the total cover.

R084AY089OK, Shallow Savannah.—This site is in areas that have a savannah

where 15 percent of the coverage is post oak, blackjack oak, and other scrub woody

species of little commercial value. The principal grasses, which make up 55 to 65

percent of the vegetation, include little bluestem, big bluestem, switchgrass,

indiangrass, and Canada wildrye. The less dominant grasses are hairy grama, tall

dropseed, and meadow dropseed. Invader plants include splitbeard, silver bluestem,

eastern redcedar, and threeawn.

R084AY095OK, Subirrigated.—This site is in an area of very deep, nearly level and

very gently sloping, sandy soils on flood plains. These soils have a high water table,

which is beneficial to plant growth. Forage production is high. Under good management,

the important plants are switchgrass, big bluestem, indiangrass, and eastern
182 Soil Survey

gamagrass. If the site is subject to continual abuse, tall dropseed, sideoats grama,

sedges, willow, and cottonwood increase in abundance.

R084AY876OK, Reseeded Sandy Savannah.—This site is in areas where former

cropland is typically seeded to a mixture of big bluestem, little bluestem, indiangrass,

switchgrass, sideoats grama, and other grasses. If the land is abused, these plants are

replaced by red lovegrass, gummy lovegrass, dropseeds, Scribner panicum, fall

witchgrass, wild buckwheat, ragweed, and sandbur.

R084AY889OK, Reseeded Shallow Savannah.—This site is in areas where the

principal seeded grasses are little bluestem, blue grama, and sideoats grama. Other

grasses include big bluestem, indiangrass, and switchgrass. As the site deteriorates,

grasses such as red lovegrass, mourning lovegrass, and splitbeard bluestem increase in

abundance.

204 Soil Survey

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 the soils in Noble County.

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 the local office of the

Natural Resources Conservation Service or the Cooperative Extension Service or from a

local nursery.

220 Soil Survey

Recreation

The soils of the survey area are rated in tables “Recreational Development, Part I”

and “Recreational Development, Part 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 tables “Recreational Development, Part I” and “Recreational

Development, Part II” 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.
Noble County, Oklahoma 221

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 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

242 Soil Survey

Engineering

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

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

features are identified. Ratings are given for sanitary facilities, waste management,

building site development, construction materials, and water management. The ratings

are based on observed performance of the soils and on the estimated data and test data

in the “Soil Properties” section.

Information in this section is intended for land use planning, for evaluating land use

alternatives, and for planning site investigations prior to design and construction. The

information, however, has limitations. For example, estimates and other data generally

apply only to that part of the soil within a depth of 6 feet. Because of the map scale,

small areas of different soils may be included within the mapped areas of a specific soil.

The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel experienced in the design and

construction of engineering works.

Government ordinances and regulations that restrict certain land uses or impose

specific design criteria were not considered in preparing the information in this section.

Local ordinances and regulations should be considered in planning, in site selection, and

in design.

Soil properties, site features, and observed performance were considered in determining the ratings in this section. During the fieldwork for this soil survey, determinations

were made about grain-size distribution, liquid limit, plasticity index, soil reaction, depth

to bedrock, hardness of bedrock within 5 or 6 feet of the surface, soil wetness, depth to

a seasonal high water table, slope, likelihood of flooding, natural soil structure aggregation, and soil density. Data were collected about kinds of clay minerals, mineralogy of

the sand and silt fractions, and the kinds of adsorbed cations. Estimates were made for

erodibility, permeability, corrosivity, shrink-swell potential, available water capacity, and

other behavioral characteristics affecting engineering uses.

This information can be used to evaluate the potential of areas for residential,

commercial, industrial, and recreational uses; make preliminary estimates of construction conditions; evaluate alternative routes for roads, streets, highways, pipelines, and

underground cables; evaluate alternative sites for sanitary landfills, septic tank absorption fields, and sewage lagoons; plan detailed onsite investigations of soils and geology;

locate potential sources of gravel, sand, earthfill, and topsoil; plan drainage systems,

irrigation systems, ponds, terraces, and other structures for soil and water conservation;

and predict performance of proposed small structures and pavements by comparing the

performance of existing similar structures on the same or similar soils.

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

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

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

and are defined in the Glossary.

Sanitary Facilities

The tables “Sanitary Facilities, Part I” and “Sanitary Facilities, Part II” show the

degree and kind of soil limitations that affect septic tank absorption fields, sewage

lagoons, sanitary landfills, and daily cover for landfill. The ratings are both verbal and

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

the soil features that affect these uses.

Not limited indicates that the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected.

Somewhat limited indicates that the soil has features that are moderately favorable
Noble County, Oklahoma 243

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).

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.

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.
244 Soil Survey

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.

Area sanitary landfill is an area where 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.

268 Soil Survey

Building Site Development

Soil properties influence the development of building sites, including the selection of

the site, the design of the structure, construction, performance after construction, and

maintenance. The tables “Building Site Development, Part I” and “Building Site

Development, Part II” show the degree and kind of soil limitations that affect dwellings

with and without basements, small commercial buildings, local roads and streets,

shallow excavations, and lawns and landscaping. The ratings in the tables are both

verbal and numerical. Rating class terms indicate the extent to which the soils are

limited by all of the soil features that affect building site development.

Not limited indicates that the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected.

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

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

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

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

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

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

high maintenance can be expected. Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to

1.00. They indicate gradations between the point at which a soil feature has the greatest

negative impact on the use (1.00) and the point at which the soil feature is not a

limitation (0.00).

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

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

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

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

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

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

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

that affect excavation and construction costs. The properties that affect the loadsupporting capacity include depth to a water table, ponding, flooding, subsidence, linear

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

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

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

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

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

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

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

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

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

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

the load-supporting capacity include depth to a water table, ponding, flooding,

subsidence, linear extensibility (shrink-swell potential), and compressibility (which is

inferred from the Unified classification). The properties that affect the ease and amount

of excavation include flooding, depth to a water table, ponding, slope, depth to bedrock

or a cemented pan, hardness of bedrock or a cemented pan, and the amount and size of

rock fragments.

Local roads and streets have an all-weather surface and carry automobile and light

truck traffic all year. They have a subgrade of cut or fill soil material; a base of gravel,

crushed rock, or soil material stabilized by lime or cement; and a surface of flexible

material (asphalt), rigid material (concrete), or gravel with a binder. The ratings are based

on the soil properties that affect the ease of excavation and grading and the traffic-
Noble County, Oklahoma 269

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

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

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

that affect the traffic-supporting capacity are soil strength (as inferred from the AASHTO

group index number), subsidence, linear extensibility (shrink-swell potential), the

potential for frost action, depth to a water table, and ponding.

Shallow excavations are trenches or holes dug to a maximum depth of 5 or 6 feet for

graves, utility lines, open ditches, or other purposes. The ratings are based on the soil

properties that influence the ease of digging and the resistance to sloughing. Depth to

bedrock or a cemented pan, hardness of bedrock or a cemented pan, the amount of

large stones, and dense layers influence the ease of digging, filling, and compacting.

Depth to the seasonal high water table, flooding, and ponding may restrict the period

when excavations can be made. Slope influences the ease of using machinery. Soil

texture, depth to the water table, and 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

Construction Materials

The tables “Construction Materials, Part I” and “Construction Materials, Part II” give

information about the soils as potential sources of gravel, sand, reclamation material,

roadfill, and topsoil. Normal compaction, minor processing, and other standard

construction practices are assumed.

Sand and gravel are natural aggregates suitable for commercial use with a minimum

of processing. They are used in many kinds of construction. Specifications for each use

vary widely. In the table “Construction Materials, Part I,” only the likelihood of finding

material in suitable quantity is evaluated. The suitability of the material for specific

purposes is not evaluated, nor are factors that affect excavation of the material. The

properties used to evaluate the soil as a source of sand or gravel are gradation of grain

sizes (as indicated by the Unified classification of the soil), the thickness of suitable

material, and the content of rock fragments. If the bottom layer of the soil contains sand

or gravel, the soil is considered a likely source regardless of thickness. The assumption

is that the sand or gravel layer below the depth of observation exceeds the minimum

thickness. The soils are rated good, fair, or poor as potential sources of sand and gravel.

A rating of good or fair means that the source material is likely to be in or below the soil.

The bottom layer and the thickest layer of the soils are assigned numerical ratings.

These ratings indicate the likelihood that the layer is a source of sand or gravel. The

number 0.00 indicates that the layer is a poor source. The number 1.00 indicates that

the layer is a good source. A number between 0.00 and 1.00 indicates the degree to

which the layer is a likely source.

The soils are rated good, fair, or poor as potential sources of topsoil, reclamation

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

specified in the table “Construction Materials, Part II.” The numerical ratings given after

the specified features indicate the degree to which the features limit the soils as

sources of topsoil, reclamation material, or roadfill. The lower the number, the greater the

limitation.

Reclamation material is used in areas that have been drastically disturbed by surface

mining or similar activities. When these areas are reclaimed, layers of soil material or

unconsolidated geological material, or both, are replaced in a vertical sequence. The

reconstructed soil favors plant growth. The ratings in the table do not apply to quarries

and other mined areas that require an offsite source of reconstruction material. The

ratings are based on the soil properties that affect erosion and stability of the surface

and the productive potential of the reconstructed soil. These properties include the

content of sodium, salts, and calcium carbonate; reaction; available water capacity;

erodibility; texture; content of rock fragments; and content of organic matter and other

features that affect fertility.

Roadfill is soil material that is excavated in one place and used in road embankments

in another place. In this table, the soils are rated as a source of roadfill for low embankments, generally less than 6 feet high and less exacting in design than higher embankments. The ratings are for the whole soil, from the surface to a depth of about 5 feet. It

is assumed that soil layers will be mixed when the soil material is excavated and

spread. The ratings are based on the amount of suitable material and on soil properties

that affect the ease of excavation and the performance of the material after it is in place.

The thickness of the suitable material is a major consideration. The ease of excavation

is affected by large stones, depth to a water table, and slope. How well the soil performs

in place after it has been compacted and drained is determined by its strength (as

inferred from the AASHTO classification of the soil) and linear extensibility (shrink-swell

potential).

Topsoil is used to cover an area so that vegetation can be established and maintained. The upper 40 inches of a soil is evaluated for use as topsoil. Also evaluated is

the reclamation potential of the borrow area. The ratings are based on the soil properties
292 Soil Survey

that affect plant growth; the ease of excavating, loading, and spreading the material; and

reclamation of the borrow area. Toxic substances, soil reaction, and the properties that

are inferred from soil texture, such as available water capacity and fertility, affect plant

growth. The ease of excavating, loading, and spreading is affected by rock fragments,

slope, depth to a water table, soil texture, and thickness of suitable material. Reclamation of the borrow area is affected by slope, depth to a water table, rock fragments,

depth to bedrock or a cemented pan, and toxic material. The surface layer of most soils

is generally preferred for topsoil because of its organic matter content. Organic matter

greatly increases the absorption and retention of moisture and nutrients for plant growth.

Construction Materials, Part I

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

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

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

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

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

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

 for further explanation of ratings in this table)

Water Management

The table “Water Management” gives information on the soil properties and site

features that affect water management. The degree and kind of soil limitations are given

for pond reservoir areas; embankments, dikes, and levees; and aquifer-fed excavated

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

to which the soils are limited by all of the soil features that affect these uses.

Not limited indicates that the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected.

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

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

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

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

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

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

high maintenance can be expected.

Numerical ratings in the 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.

Water Management

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

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

 The larger the value, the greater the limitation. See text for further explanation of

 ratings in this table)

Data relating to soil properties are collected during the course of the soil survey. The

data and the estimates of soil and water features, listed in tables, are explained on the

following pages.

Soil properties are determined by field examination of the soils and by laboratory

index testing of some benchmark soils. Established standard procedures are followed.

During the survey, many shallow borings are made and examined to identify and

classify the soils and to delineate them on the soil maps. Samples are taken from

some typical profiles and tested in the laboratory to determine grain-size distribution,

plasticity, and compaction characteristics.

Estimates of soil properties are based on field examinations, on laboratory tests of

samples from the survey area, and on laboratory tests of samples of similar soils in

nearby areas. Tests verify field observations, verify properties that cannot be estimated

accurately by field observation, and help to characterize key soils.

The estimates of soil properties shown in the tables include the range of grain-size

distribution and Atterberg limits, the engineering classification, and the physical and

chemical properties of the major layers of each soil. Pertinent soil and water features

also are given.

Engineering Index Properties

The table “Engineering Index Properties” gives estimates of the engineering

classification and of the range of index properties for the major layers of each soil in

the survey area. Most soils have layers of contrasting properties within the upper 5 or 6

feet.

Depth to the upper and lower boundaries of each layer is indicated. The range in

depth and information on other properties of each layer are given in the section “Soil

Series and Their Morphology.”

Texture is given in the standard terms used by the U.S. Department of Agriculture.

These terms are defined according to percentages of sand, silt, and clay in the fraction

of the soil that is less than 2 millimeters in diameter. “Loam,” for example, is soil that is

7 to 27 percent clay, 28 to 50 percent silt, and less than 52 percent sand. If the content

of particles coarser than sand is as much as 15 percent, an appropriate modifier is

added, for example, “gravelly.” Textural terms are defined in the Glossary.

Classification of the soils is determined according to the system adopted by the

American Association of State Highway and Transportation Officials (1) and the Unified

soil classification system (2).

The Unified system classifies soils according to properties that affect their use as

construction material. Soils are classified according to grain-size distribution of the

fraction less than 3 inches in diameter and according to plasticity index, liquid limit,

and organic matter content. Sandy and gravelly soils are identified as GW, GP, GM,

GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, OL, MH, CH, and OH; and

highly organic soils as PT. Soils exhibiting engineering properties of two groups can

have a dual classification, for example, SP-SM.

The AASHTO system classifies soils according to those properties that affect

roadway construction and maintenance. In this system, the fraction of a mineral soil

Soil Properties
330 Soil Survey

that is less than 3 inches in diameter is classified in one of seven groups from A-1

through A-7 on the basis of grain-size distribution, liquid limit, and plasticity index. Soils

in group A-1 are coarse grained and low in content of fines (silt and clay). At the other

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

A-8 on the basis of visual inspection.

If laboratory data are available, the A-1, A-2, and A-7 groups are further classified as

A-1-a, A-1-b, A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additional refinement,

the suitability of a soil as subgrade material can be indicated by a group index number.

Group index numbers range from 0 for the best subgrade material to 20 or higher for the

poorest.

Rock fragments larger than 10 inches in diameter and 3 to 10 inches in diameter are

indicated as a percentage of the total soil on a dry-weight basis. The percentages are

estimates determined mainly by converting volume percentage in the field to weight

percentage.

Percentage (of soil particles) passing designated sieves is the percentage of the soil

fraction less than 3 inches in diameter based on an ovendry weight. The sieves,

numbers 4, 10, 40, and 200 (USA Standard Series), have openings of 4.76, 2.00,

0.420, and 0.074 millimeters, respectively. Estimates are based on laboratory tests of

soils sampled in the survey area and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits) indicate the plasticity

characteristics of a soil. The estimates are based on test data from the survey area or

from nearby areas and on field examination.

378 Soil Survey

Physical Properties

The table “Physical Properties of the Soils” shows estimates of some characteristics

and features that affect soil behavior. These estimates are given for the major layers of

each soil in the survey area. The estimates are based on field observations and on test

data for these and similar soils.

Depth to the upper and lower boundaries of each layer is indicated. The range in

depth and information on other properties of each layer are given in the series

descriptions section of this survey.

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

2 millimeters in diameter. 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, or component, consists of mineral soil particles that are

less than 0.002 millimeter in diameter. The estimated clay content of each major soil

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

millimeters in diameter.

The amount and kind of clay greatly affect the fertility and physical condition of the

soil. They determine the ability of the soil to adsorb cations and to retain moisture. They

influence shrink-swell potential, permeability, plasticity, the ease of soil dispersion, and

other soil properties. The amount and kind of clay in a soil also affect tillage and earthmoving operations.

Moist bulk density is the weight of soil (ovendry) per unit volume. Volume is

measured when the soil is at field moisture capacity, that is, the moisture content at

1

/3-bar moisture tension. Weight is determined after drying the soil at 105 degrees C. In

the table “Physical Properties of the Soils,” the estimated moist bulk density of each

major soil horizon is expressed in grams per cubic centimeter of soil material that is

less than 2 millimeters in diameter. Bulk density data are used to compute shrink-swell

potential, available water capacity, total pore space, and other soil properties. The

moist bulk density of a soil indicates the pore space available for water and roots. A

bulk density of more than 1.6 can restrict water storage and root penetration. Moist bulk

density is influenced by texture, kind of clay, content of organic matter, and soil

structure.

Permeability (Ksat) refers to the ability of a soil to transmit water or air. The term

“permeability,” as used in soil surveys, indicates saturated hydraulic conductivity (Ksat).

The estimates in the table indicate the rate of water movement, in inches per hour,

when the soil is saturated. They are based on soil characteristics observed in the field,

particularly structure, porosity, and texture. Permeability is considered in the design of

soil drainage systems and septic tank absorption fields.

Available water capacity refers to the quantity of water that the soil is capable of

storing for use by plants. The capacity for water storage is given in inches of water per

inch of soil for each major soil layer. The capacity varies, depending on soil properties

that affect the retention of water and the depth of the root zone. The most important

properties are the content of organic matter, soil texture, bulk density, and soil

structure. Available water capacity is an important factor in the choice of plants or

crops to be grown and in the design and management of irrigation systems. Available

water capacity is not an estimate of the quantity of water actually available to plants at

any given time.

Linear extensibility refers to the change in length of an unconfined clod as moisture

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

change between the water content of the clod at 1/3- or 1/10-bar tension (33kPa or 10kPa

tension) and oven dryness. The volume change is reported in the table as percent
Noble County, Oklahoma 379

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. The estimated content of organic matter is expressed as a percentage,

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

The content of organic matter in a soil can be maintained or increased by returning

crop residue to the soil. Organic matter affects the available water capacity, infiltration

rate, and tilth. It is a source of nitrogen and other nutrients for crops.

Erosion factors.—Soil erodibility (K) and soil-loss tolerance (T) factors are used in

an equation that predicts the amount of soil lost through water erosion in areas of

cropland. The procedure for predicting soil loss is useful in guiding the selection of soil

and water conservation practices.

Erosion factor K factor indicates the susceptibility of a soil to sheet and rill erosion

by water. Factor K is one of six factors used in the Universal Soil Loss Equation

(USLE) to predict the average rate of soil loss by sheet and rill erosion in tons per acre

per year. The soil properties that influence erodibility are those that affect the infiltration

rate, the movement of water through the soil, and the water storage capacity of the soil

and those that allow the soil to resist dispersion, splashing, abrasion, and the

transporting forces of rainfall and runoff. The most important soil properties are the

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

content of organic matter, soil structure, and permeability. The estimates are modified

by the presence of rock fragments. Values of K range from 0.02 to 0.64. The higher the

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

Erosion factor 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. This is one of the factors used in the revised Universal

Soil Loss Equation.

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

or water that can occur over a sustained period without affecting crop productivity. The

rate is expressed in tons of soil loss per acre per year. Ratings of 1 to 5 are used,

depending on soil properties and prior erosion. The criteria used in assigning a T factor

to a soil include maintenance of an adequate rooting depth for crop production,

potential reduction of crop yields, maintenance of water-control structures affected by

sedimentation, prevention of gullying, and the value of nutrients lost through erosion.

Wind erodibility groups.—Wind erodibility is directly related to the percentage of dry,

nonerodible surface soil aggregates larger than 0.84 millimeter in diameter. From this

percentage, the wind erodibility index factor (I) is determined. This factor is an

expression of the stability of the soil aggregates, or the extent to which they are broken

down by tillage and the abrasion caused by windblown soil particles. Soils are assigned

to wind erodibility groups (WEGs) 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.
380 Soil Survey

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

loam.

WEG 4. Clay, silty clay, and noncalcareous clay loam and silty clay loam with

more than 35 percent clay.

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

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

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

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

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

noncalcareous clay loam with less than 35 percent clay.

WEG 7. Silt, noncalcareous silty clay loam with less than 35 percent clay, and

fibric organic soil material.

WEG 8. Soils that are not susceptible to soil blowing because of rock fragments on

the surface or because of surface wetness.

Wind erodibility index is a numerical value indicating the susceptibility of soil to soil

blowing, or the tons per acre per year that can be expected to be lost to soil blowing.

There is a close correlation between soil blowing and the size and durability of surface

clods, rock fragments, organic matter, and a calcareous reaction. Soil moisture and

frozen soil layers also influence soil blowing.

Additional information about wind erodibility groups and K, Kf, T, and I factors can be

obtained from the local office of the Natural Resources Conservation Service or the

Cooperative Extension Service.

Physical Analyses of Selected Soils

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

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

The pedons are representative of the series described in the section “Soil Series and

Their Morphology.” Soil samples were analyzed by the Soil Survey Laboratory, Lincoln,

Nebraska.

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

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

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

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

parentheses refer to published methods (10).

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

material less than 2 mm (3A1).

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

less than 2 mm (3A1).

Sand—(0.05-2.0 mm fraction) weight percentages of material less than 2 mm (3A1).

406 Soil Survey

Chemical Properties

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

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

major layers of each soil in the survey area. The estimates are based on field

observations and on test data for these and similar soils.

Depth to the upper and lower boundaries of each layer is indicated. The range in

depth and information on other properties of each layer are given in the series

descriptions section of this survey.

Cation-exchange capacity is the total amount of exchangeable cations that can be

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

neutrality (pH 7.0) or at some other stated pH value. Soils having a low cationexchange capacity hold fewer cations and may require more frequent applications of

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

pollution of ground water.

Soil reaction is a measure of acidity or alkalinity and is expressed as a range in pH

values. The range in pH of each major horizon is based on many field tests. For many

soils, values have been verified by laboratory analyses. Soil reaction is important in

selecting crops and other plants, in evaluating soil amendments for fertility and

stabilization, and in determining the risk of corrosion.

Calcium carbonate equivalent is the percent of carbonates, by weight, in the soil.

The availability of plant nutrients is influenced by the amount of carbonates in the soil.

Incorporating nitrogen fertilizer into calcareous soils helps to prevent nitrite

accumulation and ammonium-N volatilization.

Gypsum is given as the percent, by weight, of hydrated calcium sulfates in the soil.

Gypsum is partially soluble in water and can be dissolved and removed by water. Soils

that have a high content of gypsum (more than 10 percent) may collapse if the gypsum

is removed by percolating water.

Salinity is a measure of soluble salts in the soil at saturation. It is expressed as the

electrical conductivity of the saturation extract, in millimhos per centimeter

(decisiemens per meter) at 25 degrees C. Estimates are based on field and laboratory

measurements at representative sites of nonirrigated soils. The salinity of irrigated soils

is affected by the quality of the irrigation water and by the frequency of water

application. Hence, the salinity of soils in individual fields can differ greatly from the

value given in the table. Salinity affects the suitability of a soil for crop production, the

stability of the soil if used as construction material, and the potential of the soil to

corrode metal and concrete.

Sodium adsorption ratio is the measure of sodium relative to calcium and

magnesium in the water extract from saturated soil paste. Soils having a sodium

adsorption ratio of 13 or more may be characterized by an increased dispersion of

organic matter and clay particles, reduced permeability and aeration, and a general

degradation of soil structure.

422 Soil Survey

Chemical Analyses of Selected Soils

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

Properties of Selected Soils” in this section. The data are for soils sampled at carefully

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

”Soil Series and Their Morphology.” Soil samples were analyzed by the Soil Survey

Laboratory, Lincoln, Nebraska.

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

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

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

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

parentheses refer to published methods.

Extractable cations—ammonium acetate pH 7.0, atomic absorption; calcium (6N2e),

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

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

Exchangeable sodium percentage—ammonium acetate, pH 7.0 (5D2).

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

Carbonate as calcium carbonate—Manometer, electronic (6E1g).

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

Additional Chemical and Physical Analyses of Selected

Soils

The results of chemical and physical analyses of several pedons are given in the

tables “Additional Chemical and Physical Properties of Selected Soils”, “Clay

Mineralogy of Selected Soils”, and “Sand-Silt Mineralogy of Selected Soils.” The data

are for soils sampled at carefully selected sites. The pedons are representative of the

series described in the section “Soil Series and Their Morphology.” Soil samples were

analyzed by the Soil Survey Laboratory, Lincoln, Nebraska.

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

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

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

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

parentheses refer to published methods (10).

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

sulfate titration (6A1c).

Ratio—CEC to non-carbonate clay (8D1).

Ratio—15-bar water to non-carbonate clay (8D1).

Bulk density—saran coated clods, 1/3-bar desorption I (4A1d).

Bulk density—saran coated clods, ovendry (4A1h).

Coefficient of linear extensibility (COLE)—air-dry or ovendry to 1/3-bar tension (4D1).

Water retention—natural clods 1/3-bar (4B1c).

Water retention—natural clods 15-bar (4B1c).

Water retention difference—between 1/3- and 15-bar tension (4C1).

Clay mineralogy—x-ray diffraction, thin film on glass, resin pretreatment II (7A2i).

Sand-silt mineralogy—optical analysis, grain mounts, epoxy (7B1a).

Water Features

The table “Water Features” gives estimates of various water features. The estimates

are used in land use planning that involves engineering considerations.

Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned

to one of four groups according to the rate of water infiltration when the soils are not

protected by vegetation, are thoroughly wet, and receive precipitation from longduration storms.

The four hydrologic soil groups are:

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

wet. These consist mainly of deep, well drained to excessively drained sands or

gravelly sands. These soils have a high rate of water transmission.

Group B. Soils having a moderate infiltration rate when thoroughly wet. These

consist chiefly of moderately deep or deep, moderately well drained or well drained

soils that have moderately fine texture to moderately coarse texture. These soils have

a moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when thoroughly wet. These consist

chiefly of soils having a layer that impedes the downward movement of water or soils

of moderately fine texture or fine texture. These soils have a slow rate of water

transmission.

Group D. Soils having a very slow infiltration rate (high runoff potential) when

thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential,

soils that have a high water table, soils that have a claypan or clay layer at or near the

surface, and soils that are shallow over nearly impervious material. These soils have a

very slow rate of water transmission.

The months in the table indicate the portion of the year in which the feature is most

likely to be a concern.

Water table refers to a saturated zone in the soil. The table “Water Features”

indicates, by month, depth to the top (upper limit) and base (lower limit) of the

saturated zone in most years. Estimates of the upper and lower limits are based mainly

on observations of the water table at selected sites and on evidence of a saturated

zone, namely grayish colors or mottles (redoximorphic features) in the soil. A saturated

zone that lasts for less than a month is not considered a water table.

Ponding is standing water in a closed depression. Unless a drainage system is

installed, the water is removed only by percolation, transpiration, or evaporation. The

table indicates surface water depth and the duration and frequency of ponding. Duration

is expressed as very brief if less than 2 days, brief if 2 to 7 days, long if 7 to 30 days,

and very long if more than 30 days. Frequency is expressed as none, rare, occasional,

and frequent. None means that ponding is not probable; rare that it is unlikely but

possible under unusual weather conditions (the chance of ponding is nearly 0 percent

to 5 percent in any year); occasional that it occurs, on the average, once or less in 2

years (the chance of ponding is 5 to 50 percent in any year); and frequent that it

occurs, on the average, more than once in 2 years (the chance of ponding is more than

50 percent in any year).

Flooding, the temporary inundation of an area, is caused by overflowing streams, by

runoff from adjacent slopes, or by tides. Water standing for short periods after rainfall or

snowmelt is not considered flooding, and water standing in swamps and marshes is

considered ponding rather than flooding.

Duration and frequency are estimated. Duration is expressed as extremely brief if 0.1

hour to 4 hours, very brief if 4 hours to 2 days, brief if 2 to 7 days, long if 7 to 30 days,

and very long if more than 30 days. Frequency is expressed as none, very rare, rare,

occasional, frequent, and very frequent. None means that flooding is not probable; very

rare that it is very unlikely but possible under extremely unusual weather conditions

(the chance of flooding is less than 1 percent in any year); rare that it is unlikely but
436 Soil Survey

possible under unusual weather conditions (the chance of flooding is 1 to 5 percent in

any year); occasional that it occurs infrequently under normal weather conditions (the

chance of flooding is 5 to 50 percent in any year); frequent that it is likely to occur often

under normal weather conditions (the chance of flooding is more than 50 percent in any

year but is less than 50 percent in all months in any year); and very frequent that it is

likely to occur very often under normal weather conditions (the chance of flooding is

more than 50 percent in all months of any year).

The information is based on evidence in the soil profile, namely thin strata of gravel,

sand, silt, or clay deposited by floodwater; irregular decrease in organic matter content

with increasing depth; and little or no horizon development.

Also considered are local information about the extent and levels of flooding and the

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

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

surveys that delineate flood-prone areas at specific flood frequency levels.

Water Features

(Depths of layers are in feet. See text for definitions of terms used in this table. Estimates

 of the frequency of ponding and flooding apply to the whole year rather than to individual

 months. Absence of an entry indicates that the feature is not a concern or that data were

 not estimated)

Soil Features

The table “Soil Features” gives 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 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 mainly to pavements

and other rigid structures.

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

action that dissolves or weakens uncoated steel or concrete. The rate of corrosion of

uncoated steel is related to such factors as soil moisture, particle-size distribution,

acidity, and electrical conductivity of the soil. The rate of corrosion of concrete is based

mainly on the sulfate and sodium content, texture, moisture content, and acidity of the

soil. Special site examination and design may be needed if the combination of factors

results in a severe hazard of corrosion. The steel in installations that intersect soil

boundaries or soil layers is more susceptible to corrosion than steel in installations that

are entirely within one kind of soil or within one soil layer.

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

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

electrical conductivity of the saturation extract.

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

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

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

six categories (11, 12). Beginning with the broadest, these categories are the order,

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

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

measurements. The table “Classification of the Soils” lists each soil series in the survey

area and gives its classification. The categories are defined in the following paragraphs.

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

dominant soil-forming processes and the degree of soil formation. Each order is identified by a word ending in sol. An example is Mollisol.

SUBORDER. Each order is divided into suborders primarily on the basis of properties that influence soil genesis and are important to plant growth or properties that

reflect the most important variables within the orders. The last syllable in the name of a

suborder indicates the order. An example is Ustoll (Ust, meaning dry, plus oll, from

Mollisol).

GREAT GROUP. Each suborder is divided into great groups on the basis of close

similarities in kind, arrangement, and degree of development of pedogenic horizons; soil

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

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

is Argiustolls (Argi, meaning argillic horizonation, plus ustoll, the suborder of the

Mollisols that has an ustic moisture regime).

SUBGROUP. Each great group has a typic subgroup. Other subgroups are intergrades or extragrades. The typic is the central concept of the great group; it is not

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

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

group but do not indicate transitions to any other known kind of soil. Each subgroup is

identified by one or more adjectives preceding the name of the great group. An example

is Udic Argiustolls.

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

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

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

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

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

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

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

mixed, thermic Udic Argiustolls.

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

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

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

of the substratum can differ within a series.

Soil Series and Their Morphology

In this section, arranged in alphabetical order, each soil series recognized in the

survey area is described. Characteristics of the soil and the material in which it formed

are identified for each soil series. In addition, the physiographic region, province, and

subprovince are specified for most of the series (6). A pedon, a small three-dimensional

area of soil, which is typical of the series in the survey area is described. The detailed

description of each soil horizon follows standards in the “Soil Survey Manual” (15). Many

of the technical terms used in the descriptions are defined in “Soil Taxonomy” (12) and

“Keys to Soil Taxonomy” (11). Following the pedon description is the range of important

characteristics of the soils in the series.

The map units of each soil series are described in the section “Detailed Soil Map

This section discusses the factors of soil formation and how they relate to the soils in

Noble County. It also discusses the geology of the survey area.

Factors of Soil Formation

The following paragraphs describe the five factors of soil formation—climate, living

organisms, topography, parent material, and time. The combined influence of these

factors determines the characteristics and properties of a soil.

Climate

Noble County has a moist, subhumid climate. Because the climate is fairly uniform

throughout the county, differences among soils cannot be attributed to differences in

climate based on the present climatic regime. Moisture and warm temperatures have

been sufficient for the formation of distinct layers in many of the soils. Soil leaching is

moderate. The physical abrasion and redistribution of materials by wind action

contributes to soil formation. Cold temperatures occur often enough and long enough in

the survey area to alter materials through the processes of freezing and thawing.

Living Organisms

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

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

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

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

and Norge, have a dark grayish brown surface layer and a moderately high content of

organic matter. Soils that formed under trees, such Harrah and Stephenville, have a

brown surface layer and a low content of organic matter.

Topography

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

movement, erosion, soil temperature, and the kind of plant cover. In Noble County, relief

is determined largely by the resistance of underlying formations to weathering and

geological erosion. The topography of the southern third of Noble County is rolling to hilly

uplands with long, narrow, very gently sloping to moderately sloping summits. The

drainage deeply dissects the uplands, thus forming broad, gently sloping to steep side

slopes with narrow flood plains. The native vegetation is a prairie savannah of post

oak and blackjack oak with an understory of tall and mid grasses. The northern two

thirds of Noble County consists of nearly level to rolling uplands with broad, nearly

level and very gently sloping summits. The native vegetation is mid and tall prairie

grasses.

Formation of the Soils
552 Soil Survey

Parent Material

Soils form in unconsolidated material, which influences the rate of formation; the

chemical, physical, and mineral composition of the soil; and the color of the soil. Soils

on the uplands in Noble County formed in material weathered from alluvium, sandstone,

and shale. Examples of soils that formed in shale are Masham and Grainola. Soils that

formed in sandstone are Darnell, Lucien, Stephenville, Coyle, and Zaneis.

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

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

of the sediment and the velocity of the streams. Soils that formed in ancient fluvial

sediments include Norge, Bethany, Teller, and Kirkland. Soils that formed in recent fluvial

sediments are Ashport, Port, Pulaski, and Gaddy.

Time

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

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

interaction of the other soil-forming factors in promoting the loss, gain, transfer, or

transformation of the constituents that make up soil horizons. Soils that have no definite

genetic horizons are young or immature. Mature or older soils are in equilibrium with their

environment and tend to have well defined horizons.

The soils in Noble County range from young to old. Bethany and Renfrow soils are

examples of old soils. Coyle and Teller soils are younger, but they have well expressed

horizons. Darnell and Masham soils are considered young soils. Although these soils

have had sufficient time to develop well expressed horizons, geological erosion has

taken away soil material almost as fast as it forms because the soils are in sloping

areas. Ashport and Pulaski soils are young soils that formed in recent sediments on

flood plains. These soils show little horizon development.

Geology

Kenneth S. Johnson, Oklahoma Geological Survey, the University of Oklahoma, Norman, Oklahoma,

helped prepare this section.

The surface geology of Noble County is fairly simple. It is shown on the Surface

Geology Map of the county included with the soil maps. The outcropping rocks in this

county consist of reddish brown shales and sandstones of Permian age. These sediments were deposited near the shores of shallow seas that once covered much of

western Oklahoma (4). In many parts of the county, these sedimentary rocks are

mantled by unconsolidated alluvium of Quaternary age that was laid down by ancient or

modern rivers and streams. Permian sandstones and Quaternary alluvium are local

sources of small or moderate amounts of fairly fresh ground water. The outcropping

Permian strata overlie older sedimentary rocks that are important petroleum reservoirs in

many parts of Oklahoma.

Subsurface rock units of sedimentary origin are about 5,500 feet thick in the eastern

part of the county and about 8,000 feet thick in the western part. These strata rest upon

a “basement” of granite and other igneous or metamorphic rocks that extends 20 to 25

miles down into the earth’s crust. These subsurface sedimentary rocks were deposited

in great, shallow seas that bordered the deep sedimentary basins of western Oklahoma,

including the Anadarko Basin to the southwest and the Arkoma Basin to the southeast.

These seas inundated the survey area intermittently from the Cambrian Period of

geologic time (about 525 million years ago) through the later part of Permian time (about

250 million years ago). Noble County is considered part of the stable platform of northcentral Oklahoma, and the various rock formations that underlie the county dip gently to

the west. The Nemaha Uplift, a series of buried, fault-bounded uplift blocks, formed
Noble County, Oklahoma 553

during Pennsylvanian time. It extends in a north-south direction in the subsurface

material, just west of Noble County.

The outcropping rocks in Noble County were deposited during the late Permian Period

(about 250 to 270 million years ago). Sands, silts, and clays were eroded from marginal

land areas that existed during this time in eastern Oklahoma and adjacent parts of

Arkansas. These materials were transported generally to the west and northwest by

streams and rivers that flowed, at the time, toward the large inland sea (Anadarko Basin)

that covered most of western Oklahoma. Noble County was close to the shoreline of this

ancient sea, and, therefore, was the site for deposition of interbedded shales, siltstones,

sandstones, and a few thin limestones (to the east) in alternating riverine, deltaic, tidalflat, and shallow marine environments.

Permian rock outcrops are typically red or reddish brown with local light gray or

greenish gray variations. The red color in these sedimentary rocks primarily results from

the presence of iron oxide minerals (e.g., hematite), which are commonly distributed

uniformly throughout the rocks. Iron oxides generally do not occur in sedimentary rocks

having grayish, greenish, or whitish colors. Soils that developed from Permian reddishcolored rocks tend to retain the hematite stain of the parent material. This tendancy

explains the red color of most of the soils in Noble County.

The oldest rocks exposed in the survey area crop out along the eastern county

boundary and are overlain by successively younger Permian strata to the west. These

outcropping strata dip gently to the west at an angle of less than 1 degree, as shown in

the east-west cross section included with the Surface Geology Map.

The parent materials of soils are generally the product of weathering and disaggregation of outcropping rock units. As such, there is a close relationship between the

physical and chemical properties of these rock formations and the soils that develop

upon them. Therefore, a description of the rock units that crop out in the county can help

to explain the character and distribution of soils.

The oldest rock unit exposed in Noble County is the Oscar Group. Oscar sediments

in Noble County have a total thickness of about 600 feet, although only the uppermost

300 feet is exposed along the eastern side of the county. This unit consists mainly of

red shale with minor interbeds of sandstone and several thin beds of limestone. The

Oscar Group is the parent material for several general soil map units, the most common

of which is the Renfrow-Grainola-Coyle general soil map unit. The loamy soils in this

map unit are gently sloping and well drained and formed in material weathered (primarily)

from shale or sandstone. In several general soil map units that are mapped on the Oscar

Group outcrop, the soils actually formed in a thin veneer of loamy alluvium covering the

bedrock.

The Oscar Group is conformably overlain by the Wellington Formation. The Wellington

Formation is approximately 850 feet thick. Its outcrops are extensive and cover about

70 percent of Noble County. The Wellington strata consist mainly of red shale with minor

sandstone beds and a thin layer of limestone nodules. The Wellington Formation is the

parent material for several general soil map units. The Norge-Bethany-Kirkland and

Renfrow-Grainola-Kingfisher-Grant general soil map units are most commonly mapped

on Wellington sediments in Noble County. The Renfrow-Grainola-Coyle and GrainolaLucien-Masham general soil map units are mapped to a lesser extent. The loamy soils

of these map units formed in alluvium weathered from shale, siltstone, or sandstone or

in a thin veneer of loamy alluvium that mantles the bedrock. Soils that developed on

Wellington sediments typically are shallow to very deep and well drained or moderately

well drained and occur on nearly level to steep slopes.

The Garber Sandstone overlies the Wellington Formation, but it is restricted to small

areas in the western part of the county. Although the Garber Sandstone has a total

thickness of about 600 feet farther west in Garfield County, the upper part of the

formation has been eroded from all parts of Noble County and only the lower 50 to 150

feet remains in the west. The Garber Sandstone deposits consist mainly of orange-
554 Soil Survey

brown to red-brown sandstone beds that are irregularly interlayered with red-brown shale

and siltstone. The Renfrow-Grainola-Kingfisher-Grant general soil map unit is most

commonly mapped on the Garber Sandstone outcrops in Noble County. The TellerKonawa and Bethany-Kirkland-Norge-Tabler general soil map units are mapped to a

lesser extent. The loamy soils in these map units typically occur on uplands and formed

in alluvium weathered from shale, siltstone, or sandstone or in a thin veneer of loamy

alluvium that mantles the bedrock. Soils developed on the Garber Sandstone outcrops

are shallow to very deep and well drained or moderately well drained and occur on nearly

level to steep slopes.

Alluvial and terrace deposits of Quaternary age in Noble County are generally 10 to

60 feet thick and consist mainly of sand, silt, and clay and some gravel. These sediments were eroded from Permian strata within and to the west of Noble County and also

from other rock units that occur west and northwest of the county and are within the

Arkansas and Cimarron River drainage basins. Quaternary sediments (deposited

approximately within the past million years) were laid down mainly as flood plain or

alluvial deposits along major rivers and streams that flowed predominantly to the east

across the county. In addition, some of the sands and silts are windblown deposits.

Terrace deposits, which consist of older alluvium left behind after a river shifts

position or cuts more deeply into underlying material, occur either as broad and level, or

hummocky and undulating, expanses that are topographically higher than, and generally

adjacent to, the present-day flood plains. They occur mainly to the northeast along the

Arkansas River but also may be present in small areas near Black Bear Creek and Red

Rock Creek. Arkansas River terrace deposits are the parent sediments for soils in the

Vanoss-Slaughterville-Teller general soil map unit. The loamy soils of this map unit are

very deep and well drained and occur on nearly level to sloping topography.

Alluvial deposits are the unconsolidated sediments in stream channels or flood plains

of present-day rivers and streams, such as the main stream tributaries of the Arkansas

River and of Red Rock, Black Bear, and Stillwater Creeks. Alluvial deposits associated

with the Arkansas River and the Salt Fork of the Arkansas River are the parent

materials for soils in the Keokuk-Goodnight-Ashport and McLain-Braman-Lela general

soil map units. These soils are very deep and somewhat poorly drained to somewhat

excessively drained and locally are clayey, loamy, or sandy. Alluvium associated with

Red Rock, Black Bear, and Stillwater Creeks makes up the parent sediments for soils in

the Port-Ashport-Pulaski general soil map unit. These loamy soils are very deep and

well drained and occur on nearly level or very gently sloping topography.

Landscape Evolution and Quaternary Geology

Surface features in Oklahoma were significantly affected by landscape evolution

processes during Quaternary (Pleistocene and Holocene) time (see the Quaternary

Geology Map). River systems flowing across Oklahoma deposited an alluvial cover over

a large part of the State. These deposits are of prime importance to agriculture in

Oklahoma, as most prime farmland is associated with soils that developed in alluvium

and wind-reworked alluvium (eolian sediments) deposited during the past two million

years. Alluvium in Noble County ranges from a few feet to more than 50 feet thick. Many

smaller areas are not identified on standard geologic maps, primarily because the

delineations are too small to be identified at the map scale. This section discusses the

nature and depositional history of Quaternary deposits and the surface (geomorphic)

features associated with these deposits in the survey area.

Depositional History

Terrace development.—Alluvial and eolian sediments associated with Pleistocene

terraces were deposited by rivers (or blown from beds of rivers) originating in the Rocky

Mountains and flowing across the High Plains and Osage Plains. The Ogallala Formation
Noble County, Oklahoma 555

of Miocene-Pliocene age and geologic formations of Permian age were dissected by

these eastward-flowing rivers, and Pleistocene alluvium, loess, and eolian sands were

deposited on this unconformity surface. Pleistocene alluvial deposits are laterally

discontinuous, and it is not always clear which stream deposited these sediments. Five

major Pleistocene terraces are recognized in Noble County. Terrace level Qt5 is the

highest terrace in Noble County and lies on the divide between the Cimarron and

Arkansas Rivers.

The north-facing escarpment (E5), which is continuous west to southeast of the town

of Perry, represents the southern boundary of an ancient Arkansas River valley. This

ancestral Arkansas River was probably a braided stream carrying sediments from the

Rocky Mountains across the High Plains and Osage Plains. According to Fay (5),

Quaternary sediments in Noble County belong to an ancient Arkansas River that flowed

southeast from the Dodge City, Kansas area and along the present course of the

Medicine Lodge River and the Salt Fork of the Arkansas River. This ancestral Arkansas

River cut escarpment E5 and formed the Qt4 terrace, which typically contains large

strips of bed-load material. Remnants of the Qt4 terrace also occur north of Red Rock

Creek, where gravel deposits are isolated on topographic highs.

Rejuvenation caused the river system to erode its valley, cut escarpment E4, and

deposit terrace Qt3. Volcanic ash in the Qt3 terrace has been dated at about

750,000 years B.P.(16) . Sediments on the Qt3 terrace are dominantly silts and clays. The

mineralogy and color of these sediments are not indicative of Permian red beds but

strongly suggest alluvial plain sediments from the Rocky Mountains. Areas of the Qt3

terrace occur in northern and central parts of Noble County and in valleys that breach

the Qt4 terrace. The Qt3 terrace deposits are further discussed in the following paragraphs with the development of Black Bear Creek and Red Rock Creek.

The Qt2 terrace in the northeastern corner of Noble County is confined to a meander

bend of the Arkansas River and is slightly lower than the Qt3 terrace. The sediment

texture and the position of the Qt2 terrace relative to the river suggest a major eolian

influence. Recent eolian soils and depositional areas on the Qt2 terrace suggest that the

prevailing wind direction and channel form facilitated the accumulation of eolian sands

and silts since (at least) late Pleistocene time. The presence of this material is also

evidence that the river generally flowed within the existing channel in this area for many

years. The river cut escarpment E2 while providing eolian material for the Qt2 terrace.

The Qt1 terrace in the northeastern part of the county is the lowest Pleistocene

terrace. It lies below escarpment E2 and is a terrace of the modern Arkansas River.

Escarpment E1 is the lowest escarpment. It is below the Qt1 terrace and immediately

above the Holocene flood plain of the Arkansas River.

Stream piracy.—Stream piracy played an important role in the development of the

modern drainage network. The pattern of sediments on the Qt3 terrace bisects the

modern drainage system and also bisects the Qt4 terrace in two valleys north of Perry.

Following deposition of the Qt4 terrace, north-south drainage developed. Two possible

scenarios could have produced this feature during the development of the Qt3 terrace. In

one scenario, the main river could have breached the Qt4 terrace and flowed to the

south into what is now the Cimarron River drainage. Terrace sediments in a wind gap in

sections 7 and 18, T. 20 N., R. 3 E. in Payne County are analogous to these sediments.

They are at the same elevation, have the same soil series, and are in line with the

southeast trend of the sediments. In a second scenario, tributaries of the main river

flowing north could have bisected the Qt4 terrace. The sediment, however, is the same

type as the main body of the Qt3 terrace. Stream piracy eventually diverted the drainage

into the modern course of Black Bear Creek and Red Rock Creek.

Additional evidence of streams flowing north or south are wind gaps in the major

divides, in line from north to south. These wind gaps are higher valleys in saddles of the

major divides that have alluvium on the valley floor but through which active streams no

longer flow. Stream piracy has diverted flow into Black Bear Creek and Red Rock Creek.
556 Soil Survey

The area of Antelope Valley (north half of section T. 22 N., R. 2 W.) is an example of an

area isolated by stream piracy. Active stream piracy is still taking place in section 7,

T. 24 N., R. 1 W. This area is in the saddle of a wind gap in the divide between the Salt

Fork of the Arkansas River and Red Rock Creek. Escarpment E3 helps define wind

gaps near the northern boundary of Noble County.

Development of Red Rock Creek and Black Bear Creek.—After the deposition of the

Qt4 and Qt3 terraces, streams forming in backwater positions of the terraces continued

to capture drainage. These creeks became deferred tributaries to the main river, flowing

from west to east. Red Rock Creek drains the Qt3 terrace, and Black Bear Creek drains

the Qt4 terrace. Both streams are younger than the terraces that they dissect. One

factor that complicates an understanding of the Qt3 terrace is the common movement of

streams down the strike of the Permian formations across Oklahoma. As Red Rock

Creek drifts southward, the terrace sediments are reworked and the elevation range of

these sediments grades into the lower terraces. South of the town of Billings and east of

the town of Red Rock, several small treads and risers in the Qt3 terrace show episodic

downcutting. The south bank of Red Rock Creek and its tributaries are cutting into

Permian formations.

Holocene flood plains.—Flood plains of Holocene age along Black Bear, Red Rock,

and Stillwater Creeks are similar in form and history. The paleosol known as the Copan

Soil is found on all Holocene flood plains and, in some places, is the land-surface soil.

This soil developed during a wet environment lasting from 2,000 to 1,000 years B.P. and

is characterized by an over-thickened, organic-rich surface (7). In many places, this

paleosol is covered by 3 to 8 feet of silty and loamy alluvium that is less than 1,000

years old. Holocene alluvium in stream valleys is derived from local Permian rocks and

Pleistocene terraces. Thickness of the alluvium ranges from 25 to 45 feet along Red

Rock Creek and from 25 to 55 feet along Black Bear Creek.

Arkansas River System.—The Salt Fork of the Arkansas River is an underfit stream

flowing in the ancestral Arkansas River valley, which was discussed above. The Salt

Fork of the Arkansas River has a Holocene meander belt much narrower than the

Pleistocene flood plain. The Pleistocene flood plain is still rarely flooded by the Salt Fork

of the Arkansas River but is relict as far as active aggradation is concerned. The flood

plain of the Salt Fork of the Arkansas River is about 5 miles wide at Tonkawa,

Oklahoma, and the Arkansas River flood plain is only about 1 mile wide where the two

rivers join about 20 miles east. The Arkansas River is now deeply entrenched into

Permian and Pennsylvanian formations, and its broad flood plain narrows as the river

cuts resistant rock layers to the east.

Exposed Permian and Pennsylvanian Materials

Areas in the figure (shown by “P”) have soils that developed in residuum from

outcropping Permian and Pennsylvanian shale and sandstone. Surface exposures

of Permian and Pennsylvanian sediments occur at all elevations within Noble County,

and some soils are mapped regardless of elevation (e.g., Grainola and Lucien soils).

Although these surfaces have different ages, ranging from middle to late Pleistocene,

mapped soils show the same degree of pedogenesis whether high or low in elevation.

One possible explanation for this discrepancy is that the soil-forming processes on

these landscapes are offset somewhat by geologic erosion, thus youthful characteristics

are maintained in the soil profiles.

Faulting in bedrock at depth is common. Most faulting occurred during Pennsylvanian

time. Subsequent movement produced gentle folds at the surface, although associated

faults do not normally reach the surface.

Characteristics of terrace deposits and escarpments.—The other important

geomorphic features in Noble County are the many escarpments throughout the survey

area and the relict, high, isolated river valleys (wind gaps). The escarpments are

dissected and of (primarily) Pleistocene age, and some have slopes as low as 5
Noble County, Oklahoma 557

percent. High valleys have alluvium on the valley floor and walls and correlate with

valleys on other divides in this area. The terrace deposits mapped in the county are

delineated based on elevation, soil series, texture, drainage density, and associated

escarpments.

Terrace Level 5.—The highest and oldest terrace (Qt5) caps the divide between the

Cimarron and Arkansas Rivers. This is a fining-upward terrace with thick sand deposits

overlain by clayey and silty surfaces. The soils mapped on this level are mostly

Paleustolls, typically Kirkland soils. This terrace is well dissected, and only small

remnants remain in Noble County.

Terrace Level 4.—The Qt4 terrace lies at the base of escarpment E5, at an elevation

of 1,050 to 1,125 feet. This terrace occurs mostly in the south-central part of the county,

although outliers also occur on topographic highs, capping Permian rocks north of Red

Rock Creek. Although the Qt4 terrace is also a fining-upward terrace, finer surface

sediment overlies thick deposits of bed-load sands and gravel. These deposits provide

large amounts of gravel and sand for construction. Laboratory data shows that the

surface layer of the Qt4 terrace has a loessial influence, but the loess layer is thin and

mixed with underlying alluvium. The soils mapped on this level are Argiustolls and

Paleustolls. Wisby, Milan, and Lovedale soils are associated with sandy and gravelly

bed-load deposits. Bethany and Norge soils are associated with silty surface layers. The

Qt4 terrace is well dissected, and erosion has isolated several areas on interfluves in

the eastern part of Noble County.

Terrace Level 3.—The Qt3 terrace lies below escarpment E4 at an elevation of 950 to

1,050 feet. This terrace is composed dominantly of silty and clayey sediments with sand

and gravel as minor components. Laboratory data shows that the surface layer of the

Qt3 terrace also has a loessial influence, but these layers are also thin and mixed with

underlying alluvium. The soils mapped on this level are Paleustolls and Argiustolls,

including Kirkland, Bethany, Tabler, and Norge soils. Norge soils are commonly mapped

near Red Rock Creek where either basal sediments are exposed or sediments have

been reworked by the migrating stream. The Qt3 terrace is the most susceptible surface

to formation of saline seeps in Noble County. Depth to Permian bedrock on this terrace

is less than 20 feet, and percolating water dissolves Permian salts and creates saline

seeps on slopes where a contact between the terrace material and bedrock is exposed.

The presence of Kirkland, Bethany, Norge, and Tabler soils on several terrace levels

makes delineation of these terrace levels more difficult. However, it is possible that the

fine textured soils (Kirkland, Bethany, and Tabler) have reached a steady state with the

present climate, or the differences are not discernable with present knowledge. Similar

alluvial sediments on each level also tend to produce similar soils. The drainage density

on this level is low or medium, and large areas of nearly level, well drained Kirkland soils

and moderately well drained Tabler soils are present.

Terrace Level 2.—The Qt2 terrace is confined to a large, entrenched meander of the

Arkansas River in the northeastern corner of the county. The elevation of this terrace is

950 to 1,000 feet. The Qt2 terrace sediments are mostly very fine sand, presumably

eolian. These sands cap the Permian Herington Limestone and in places are blown up

against escarpment E2 below the Herington Limestone on south-facing slopes. Soils

mapped on this level have argillic horizons, but they are not as well developed or as

thick as argillic horizons in Qt3 terrace soils. Teller soils (Udic Argiustolls) are the

dominant soils, but the soils are slightly more silty than typical for the Teller series.

Drainage density is medium.

Terrace Level 1.—The youngest terrace (Qt1) is below the Qt2 terrace level and is

directly related to the modern Arkansas River. The elevation of this terrace is 900 to 925

feet. The drainage density is very low, and the mapped soils are unique to this terrace.

Haplustolls (Minco and Slaughterville soils) formed in eolian sediments and windreworked alluvium along the first escarpment above the Arkansas River. Argiustolls

(Vanoss soils) formed on the terrace tread and in backwater positions farther from the
558

river. Several additional late Pleistocene terraces along Red Rock Creek and Black Bear

Creek are included in the Qt1 terrace level. Teller soils also occur on this level along

Black Bear Creek and Red Rock Creek.

Summary

Most prime farmland soils in Noble County formed in Quaternary alluvium. Soils and

associated water resources are the most valuable natural resources affecting the future

of agriculture in the survey area. An understanding of the extent, source, depositional

framework, and soil-geomorphic relationships of these terraces is helpful when

managing soil and water resources.

conforming to the dip of the underlying bedrock.
Noble County, Oklahoma 565

Diversion (or diversion terrace). A ridge of earth, generally a terrace, built to protect

downslope areas by diverting runoff from its natural course.

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

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

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

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

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

somewhat excessively drained, well drained, moderately well drained, somewhat

poorly drained, poorly drained, and very poorly drained. These classes are defined

in the “Soil Survey Manual.”

Drainage, surface. Runoff, or surface flow of water, from an area.

Drainageway. An area of ground at a lower elevation than the surrounding ground and

place to another within the soil. Soil horizons that have lost material through

eluviation are eluvial; those that have received material are illuvial.

upper boundary of saturation and a depth of 2 meters are saturated.

Eolian soil material. Earthy parent material accumulated through wind action;

commonly refers to sandy material in dunes or to loess in blankets on the surface.

Ephemeral stream. A stream, or reach of a stream, that flows only in direct response

to precipitation. It receives no long-continued supply from melting snow or other

source, and its channel is above the water table at all times.

Episaturation. A type of saturation indicating a perched water table in a soil in which

saturated layers are underlain by one or more unsaturated layers within 2 meters of

the surface.

Erosion. The wearing away of the land surface by water, wind, ice, or other geologic

agents and by such processes as gravitational creep.

Erosion (geologic).—Erosion caused by geologic processes acting over long

geologic periods and resulting in the wearing away of mountains and the building up

of such landscape features as flood plains and coastal plains. Synonym: natural

erosion.

Erosion (accelerated).—Erosion much more rapid than geologic erosion, mainly as

a result of human or animal activities or of a catastrophe in nature, such as a fire,

that exposes the surface.

Escarpment. A relatively continuous and steep slope or cliff breaking the general

continuity of more gently sloping land surfaces and resulting from erosion or

faulting. Synonym: scarp.

Excess fines (in tables). Excess silt and clay in the soil. The soil does not provide a

source of gravel or sand for construction purposes.

Excess lime (in tables). Excess carbonates in the soil that restrict the growth of some

plants.

Excess salts (in tables). Excess water-soluble salts in the soil that restrict the growth

of most plants.

moisture. Summer fallow is common in regions of limited rainfall where cereal grain
566 Soil Survey

is grown. The soil is tilled for at least one growing season for weed control and

decomposition of plant residue.

Fertility, soil. The quality that enables a soil to provide plant nutrients, in adequate

amounts and in proper balance, for the growth of specified plants when light,

moisture, temperature, tilth, and other growth factors are favorable.

Fibric soil material (peat). The least decomposed of all organic soil material. Peat

contains a large amount of well preserved fiber that is readily identifiable according

to botanical origin. Peat has the lowest bulk density and the highest water content

at saturation of all organic soil material.

Field moisture capacity. The moisture content of a soil, expressed as a percentage of

the ovendry weight, after the gravitational, or free, water has drained away; the field

Horizon, soil. A layer of soil, approximately parallel to the surface, having distinct

characteristics produced by soil-forming processes. In the identification of soil

horizons, an uppercase letter represents the major horizons. Numbers or lowercase

the subdivisions is given in the “Soil Survey Manual.” The major horizons of mineral

soil are as follows:

O horizon.—An organic layer of fresh and decaying plant residue.

A horizon.—The mineral horizon at or near the surface in which an accumulation of

humified organic matter is mixed with the mineral material. Also, a plowed surface

horizon, most of which was originally part of a B horizon.

E horizon.—The mineral horizon in which the main feature is loss of silicate clay,

iron, aluminum, or some combination of these.

B horizon.—The mineral horizon below an A horizon. The B horizon is in part a

layer of transition from the overlying A to the underlying C horizon. The B horizon

also has distinctive characteristics, such as (1) accumulation of clay,

sesquioxides, humus, or a combination of these; (2) prismatic or blocky structure;

(3) redder or browner colors than those in the A horizon; or (4) a combination of

these.

C horizon.—The mineral horizon or layer, excluding indurated bedrock, that is little

affected by soil-forming processes and does not have the properties typical of the

overlying soil material. The material of a C horizon may be either like or unlike that

in which the solum formed. If the material is known to differ from that in the solum,

an Arabic numeral, commonly a 2, precedes the letter C.

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

Solum. The upper part of a soil profile, above the C horizon, in which the processes of

soil formation are active. The solum in soil consists of the A, E, and B horizons.

Generally, the characteristics of the material in these horizons are unlike those of

the material below the solum. The living roots and plant and animal activities are

largely confined to the solum.

Species. A single, distinct kind of plant or animal having certain distinguishing

characteristics.

Stone line. A concentration of coarse fragments in a soil. Generally, it is indicative of

an old weathered surface. In a cross section, the line may be one fragment or more

thick. It generally overlies material that weathered in place and is overlain by recent

sediment of variable thickness.

Stones. Rock fragments 10 to 24 inches (25 to 60 centimeters) in diameter if rounded

or 15 to 24 inches (38 to 60 centimeters) in length if flat.

Stony. Refers to a soil containing stones in numbers that interfere with or prevent

tillage.

Stratified. Arranged in strata, or layers. The term refers to geologic material. Layers in

soils that result from the processes of soil formation are called horizons; those

inherited from the parent material are called strata.

Strath terrace. A surface cut formed by the erosion of hard or semiconsolidated

bedrock and thinly mantled with stream deposits.

Stream channel. The hollow bed where a natural stream of surface water flows or may

flow; the deepest or central part of the bed, formed by the main current and

covered more or less continuously by water.

Stream terrace. One of a series of platforms in a stream valley, flanking and more or

less parallel to the stream channel. It originally formed near the level of the stream

and is the dissected remnants of an abandoned flood plain, streambed, or valley

floor that were produced during a former stage of erosion or deposition.

Stripcropping. Growing crops in a systematic arrangement of strips or bands that

provide vegetative barriers to soil blowing and water erosion.

Structure, soil. The arrangement of primary soil particles into compound particles or

aggregates. The principal forms of soil structure are—platy (laminated),

prismatic (vertical axis of aggregates longer than horizontal), columnar (prisms

with rounded tops), blocky (angular or subangular), and granular.Structureless

soils are either single grained (each grain by itself, as in dune sand) or

massive (the particles adhering without any regular cleavage, as in many

hardpans).

Stubble mulch. Stubble or other crop residue left on the soil or partly worked into the

soil. It protects the soil from wind erosion and water erosion after harvest, during

preparation of a seedbed for the next crop, and during the early growing period of

the new crop.

Subsoil. Technically, the B horizon; roughly, the part of the solum below plow depth.

Subsoiling. Tilling a soil below normal plow depth, ordinarily to shatter a hardpan or

claypan.
Noble County, Oklahoma 577

Substratum. The part of the soil below the solum.

Subsurface layer. Technically, the E horizon. Generally refers to a leached horizon

lighter in color and lower in content of organic matter than the overlying surface

layer. Any surface soil horizon (A, E, AB, or EB) below the surface layer.

Summer fallow. The tillage of uncropped land during the summer to control weeds and

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

common in semiarid regions, where annual precipitation is not enough to produce a

crop every year. Summer fallow is frequently practiced before planting winter grain.

Summit. A general term for the top, or highest level, of an upland feature, such as a

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

flanked by steeper slopes.

Surface layer. The soil ordinarily moved in tillage, or its equivalent in uncultivated soil,

ranging in depth from 4 to 10 inches (10 to 25 centimeters). Frequently designated

as the “plow layer,” or the “Ap horizon.”

Surface soil. The A, E, AB, and EB horizons, considered collectively. It includes all

subdivisions of these horizons.

Tailwater. The water directly downstream of a structure.

Terrace. An embankment, or ridge, constructed across sloping soils on the contour or

at a slight angle to the contour. The terrace intercepts surface runoff so that water

soaks into the soil or flows slowly to a prepared outlet. A terrace in a field is

generally built so that the field can be farmed. A terrace intended mainly for

drainage has a deep channel that is maintained in permanent sod.

Terrace (geologic). An old alluvial plain, ordinarily flat or undulating, bordering a river, a

lake, or the sea.

Texture, soil. The relative proportions of sand, silt, and clay particles in a mass of soil.

The basic textural classes, in order of increasing proportion of fine particles, are

sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam,

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

loam classes may be further divided by specifying “coarse,” “fine,” or “very fine.”

Thin layer (in tables). Otherwise suitable soil material too thin for the specified use.

Thornthwaite PE index. The annual PE index is the sum of the 12 monthly

precipitation effectiveness indices.

Tilth, soil. The physical condition of the soil as related to tillage, seedbed preparation,

seedling emergence, and root penetration.

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

Topsoil. The upper part of the soil, which is the most favorable material for plant

growth. It is ordinarily rich in organic matter and is used to topdress roadbanks,

lawns, and land affected by mining.

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

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

Trace elements. Chemical elements, for example, zinc, cobalt, manganese, copper,

and iron, in soils in extremely small amounts. They are essential to plant growth.

Trafficability. The degree to which a soil is capable of supporting vehicular traffic

across a wide range in soil moisture conditions.

Tread. The relatively flat terrace surface that was cut or built by stream or wave action.

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

Upland (geology). Land at a higher elevation, in general, than the alluvial plain or

stream terrace; land above the lowlands along streams.

Valley. An elongated depressional area primarily developed by stream action.

Valley fill. Alluvium deposited by heavily loaded streams.

Variegation. Refers to patterns of contrasting colors assumed to be inherited from the

parent material rather than to be the result of poor drainage.

Very deep soil. A soil that is more than 60 inches deep over bedrock or to other

material that restricts the penetration of plant roots.
578

Very shallow soil. A soil that is less than 10 inches deep over bedrock or to other

material that restricts the penetration of plant roots.

Well graded. Refers to soil material consisting of coarse-grained particles that are well

distributed over a wide range in size or diameter. Such soil normally can be easily

increased in density and bearing properties by compaction. Contrasts with poorly

graded soil.

Wilting point (or permanent wilting point). The moisture content of soil, on an

ovendry basis, at which a plant (specifically a sunflower) wilts so much that it does

not recover when placed in a humid, dark chamber.
