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 1999. Soil names and

descriptions were approved in 1999. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 1999. This survey was made

cooperatively by the Natural Resources Conservation Service and the Illinois

Agricultural Experiment Station. It is part of the technical assistance furnished to the

Randolph County Soil and Water Conservation District. Funding was provided by the

Randolph County Board and the Illinois Department of Agriculture.

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

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

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

larger scale.

This soil survey contains information that affects land use planning in this survey

area. It contains predictions of soil behavior for selected land uses. The survey also

highlights soil limitations, 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, 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.

Various land use regulations of Federal, State, and local governments may impose

special restrictions on land use or land treatment. The information in this report is

intended to identify soil properties that are used in making various land use or land

treatment decisions. Statements made in this report are intended to help the land users

identify and reduce the effects of soil limitations on various land uses. The landowner or

user is responsible for identifying and complying with existing laws and regulations.

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

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

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

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

poorly suited to basements or underground installations.

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

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

survey area is described, and information on specific uses is given. 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.

RANDOLPH COUNTY is in southwestern Illinois (fig. 1).

It has an area of about 380,725 acres, or 595 square

miles. It is bordered on the north by Monroe, St. Clair,

and Washington Counties; on the east by Jackson and

Perry Counties; and on the south and west by Perry

and Ste. Genevieve Counties in Missouri and by the

Mississippi River.

This soil survey updates the survey of Randolph

County published in 1988 (Miles, 1988). It provides

additional information and has larger maps, which

show the soils in greater detail.

General Nature of the Survey Area

This section provides general information about

Randolph County. It describes history and

development, natural resources, and climate.

History and Development

In 1795, the original county of St. Clair was divided

and the southern portion became Randolph County.

Later, Randolph County was divided into Randolph,

Jackson, Monroe, and Perry Counties. The first county

seat was Kaskaskia. After a flood in 1844, the county

seat was moved to Chester, which is located on higher

ground. The county has 13 incorporated communities.

Two of the largest towns are Chester, which has a

population of about 8,204, and Sparta, which has a

population of about 4,853 (U.S. Department of

Commerce, 1990).

In 1818, when Illinois became a State, the First

General Assembly met at Kaskaskia. Because of the

need for a more central location, however, the capital

was moved to Vandalia and later to Springfield.

In the early 1800s, rapid immigration changed the

survey area from a wilderness into farmland. Fur

trading gave way to farming. Corn, cotton, and castor

beans were some of the early crops.

Transportation facilities in the county include seven

primary State highways and two major railroads.

Barge transportation service is available on the

Mississippi and Kaskaskia Rivers.

Natural Resources

Soil is the major natural resource of Randolph

County. Most of the soils are nearly level to strongly

sloping; formed in loess, or windblown silty material;

and support timber vegetation. The soils range from

clayey on flood plains to stony on very steep hillsides.

Approximately 1,100 farms make up about 75 percent

of the land area in the county (Illinois Department of

Agriculture and USDA, 1997). Soybeans, corn, and

wheat are the major crops. Secondary farm products

include hay, grain sorghum, timber, cattle, and hogs.

The county has about 41,800 acres of forestland,

mainly on the steep bluffs adjacent to the Mississippi

United States Department of Agriculture, Natural Resources Conservation Service,

in cooperation with the Illinois Agricultural Experiment Station
16 Soil Survey of

and Kaskaskia Rivers (Illinois Department of

Agriculture and USDA, 1997). Much of this acreage is

unimproved. Wildlife, such as deer, squirrel, and other

fur-bearing animals, inhabit these forested areas. The

county has more than 7,800 acres of water in streams

and lakes 40 acres or more in size. These water areas

provide ample fishing opportunities. State-owned

conservation areas, including the Kaskaskia River

Area, the Turkey Bluffs Area, and the Randolph

County Conservation Area, make up about 12,000

acres. They are open to the public for recreational

uses.

The subsurface mineral resources in the county

include coal, limestone, and oil. Coal mining has

played an important part in the development of the

county. Commercial mining began around 1900 and

rapidly became a major industry. It brought many

newcomers into the villages of Sparta, Tilden, and

Percy. Randolph County is the second leading coalproducing county in Illinois. Coal reserves are

estimated at over 700 million minable tons. As a result,

coal is the most important mineral resource in the

county. Stone and crude oil also are important mineral

resources. Stone is extracted from caverns along the

limestone bluff between Chester and the Monroe

County line. Crude oil is produced from a field in the

northeastern part of the county.

Climate

Randolph County is cold in winter and quite hot in

summer. Winter precipitation, frequently in the form of

snow, results in a good accumulation of soil moisture

by spring and minimizes drought in summer on most

soils. The normal annual precipitation is adequate for

all crops that are adapted to the temperature and

growing season in the county.

Table 1 gives data on temperature and precipitation

for the survey area as recorded at Sparta in the period

1961 to 1990. Table 2 shows probable dates of the first

freeze in fall and the last freeze in spring. Table 3

provides data on length of the growing season.

In winter, the average temperature is 35 degrees F

and the average daily minimum temperature is 26

degrees. The lowest temperature on record, which

occurred at Sparta on January 17, 1977, is -16

degrees. In summer, the average temperature is 77

degrees and the average daily maximum temperature

is 89 degrees. The highest recorded temperature,

which occurred on July 14, 1954, is 109 degrees.

Growing degree days are shown in table 1. They

are equivalent to “heat units.” During the month,

growing degree days accumulate by the amount that

the average temperature each day exceeds a base

temperature (40 degrees F). The normal monthly

accumulation is used to schedule single or successive

plantings of a crop between the last freeze in spring

and the first freeze in fall.

The total annual precipitation is 41.62 inches. Of

this total, 22.5 inches, or 54 percent, usually falls in

April through September. The growing season for most

crops falls within this period. The heaviest 1-day

rainfall on record was 5.84 inches at Sparta on August

17, 1959. Thunderstorms occur on about 50 days

each year, and most occur between April and August.

The average seasonal snowfall is 17.5 inches. The

greatest snow depth at any one time during the period

of record was 19 inches recorded on February 3,

1982. On an average, 19 days of the year have at least

1 inch of snow on the ground. The number of such

days varies greatly from year to year. The heaviest

1-day snowfall on record was 13 inches recorded on

March 8, 1978.

The average relative humidity in midafternoon is

about 60 percent. Humidity is higher at night, and the

average at dawn is about 80 percent. The sun shines

75 percent of the time possible in summer and 50

percent in winter. The prevailing wind is from the south

in the summer and from the west and northwest in the

winter and spring. Average windspeed is highest, 9

miles per hour, in March.

How This Survey Was Made

This survey was made to provide updated

information about the soils and miscellaneous areas in

Randolph County, which is a subset of Major Land

Resource Areas (MLRAs) 114B and 115B (fig. 1).

MLRAs are geographically associated land resource

units that share a common land use, elevation,

topography, climate, pattern of water and soils, and

vegetation (USDA, 1981). Map unit design is based on

the occurrence of each soil throughout the MLRAs. In

some cases a soil component may be referred to that

does not occur in the Randolph County subset but that

has been mapped within the MLRAs.

The information in this survey 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 degree of erosion; the general pattern of

drainage; the kinds of crops and native plants; and the

kinds of bedrock. To study the soil profile, which is the

sequence of natural layers, or horizons, soil scientists

examine the soil with the aid of a soil probe. 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

of landscape 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 they were formed.

Individual soils on the landscape merge into one

another as their characteristics gradually change. To

construct an accurate soil 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 soilvegetation-landscape relationship, are sufficient to

verify predictions of the kinds of soil in an area and to

determine the boundaries.

Fieldwork in Randolph County consisted primarily

of soil transects conducted by soil scientists. Soil

transects are a systematic method of sampling a

specific soil type. Soil borings are taken at regular

intervals. Soil scientists then record the characteristics

of the soil profiles that they study. They note soil 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. This information can then be used to run

statistical analyses for specific soil properties. The

results of these analyses, along with other
18

observations, enable the soil scientists to assign 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.

Aerial photographs used in this survey were taken

in 1993. Soil scientists also studied U.S. Geological

Survey topographic maps (enlarged to a scale of

1:12,000), orthophotographs, and infrared

photography to relate land and image features.

Specific soil boundaries were drawn on the

orthophotographs. Adjustments of soil boundary lines

were made to coincide with the U.S. Geological

Survey topographic map contour lines and tonal

patterns on aerial photographs.

This section relates the soils in the survey area to

the major factors of soil formation and describes the

general processes of soil formation. It also describes

the system of soil classification.

Factors of Soil Formation

Soil forms through processes that act on deposited

geologic material. The factors of soil formation are the

physical and mineralogical composition of the parent

material; the climate in which the soil formed; the plant

and animal life on and in the soil; the relief; and the

length of time during which the processes of soil

formation have acted on the parent material (Jenny,

1941).

Climate and plant and animal life are the major

active factors of soil formation. They act directly on the

parent material, either in place or after being moved

from place to place by water, wind, or glaciers, and

slowly change it into a natural body that has

genetically related horizons. Relief modifies soil

formation and can inhibit soil formation on the steeper

eroded slopes and in wet, depressional or nearly level

areas by controlling the moisture status of soils.

Finally, time is needed for changing the parent material

into a soil that has differentiated horizons.

The factors of soil formation are so closely

interrelated and conditioned by each other that few

generalizations can be made regarding the effects of

any one factor unless the effects of the other factors

are understood.

Parent Material

Parent material is the geologic material in which a

soil forms. Most of the soils of Randolph County were

derived from parent materials that are a direct or

indirect result of glaciers. The parent materials in this

survey area are loess, glacial till, alluvium, colluvium,

and lacustrine deposits. Some soils formed in

residuum, or material weathered from bedrock, and a

few soils formed as a result of surface mining

activities.

Loess, or wind-deposited silty material, is the most

extensive parent material in Randolph County. The

loess ranges in thickness from more than 25 feet near

the bluffs to less than 5 feet in the northeastern part of

the county. Menfro and Winfield soils are examples of

soils that formed in loess.

Glacial till is nonstratified drift transported and

deposited directly by glacial ice with a minimum of

water action. It is a mixture of particles of various

sizes. The small pebbles in glacial till have sharp

corners, a characteristic indicating that they have not

been worn by water. The till is acid and firm and

ranges from loam to clay, depending on the degree of

weathering. Hickory soils are examples of soils that

formed in glacial till.

Alluvium is material deposited by streams on their

flood plains. This material varies in texture, depending

on the speed of the water from which it was deposited.

Wakeland and Birds soils formed in recent silty

alluvium along the Kaskaskia River and its tributaries.

Alluvial soils on the flood plain along the Mississippi

River range from the sandy Rocher soils to the clayey

Darwin soils.

Colluvium is material moved by creep, slide, or local

wash and deposited at the base of steep slopes. In

Randolph County, the colluvium is mainly silt loam and

is at the base of the bluffs along the Mississippi River

flood plain. Drury, Raddle, and Worthen soils formed in

this material.

Lacustrine material was deposited under still or

ponded glacial meltwater. The coarser material drops

out of moving water as outwash; consequently, only

the finer material, such as silt and clay, remains to

settle out in the still water. Colp and Hurst soils formed

in about 20 inches of loess or other silty material

overlying clayey lacustrine material.

Some of the soils in the county formed in material

weathered from sandstone, siltstone, mudstone,

claystone, or limestone bedrock. The age of the

exposed bedrock in Randolph County is either

Mississippian or Pennsylvanian. Neotoma soils formed

in material weathered from siltstone and sandstone.

Brookside soils formed in material weathered from

Formation and Classification of the Soils
20 Soil Survey of

shale, siltstone, and limestone. Some soils formed in

loess or other silty material and in the underlying

bedrock residuum. Examples are Wellston and

Westmore soils. Wellston soils formed in loess and in

siltstone and sandstone residuum. Westmore soils

formed in silty material and in shale and siltstone

residuum.

Soils in surface-mined areas formed in material that

resulted from the excavation and placement or

replacement of overburden during mining activities.

Climate

The climate in Randolph County has significantly

affected the soil-forming processes. Climatic factors,

such as precipitation and temperature, have

influenced the existing plant and animal communities

and the physical and chemical weathering of the

parent material.

During the colder glacial epoch, the cold

temperatures in the soil reduced the rate of chemical

reactions in the existing soils and in the raw parent

material. Increased frost action, resulting from the

periglacial climate, caused frost churning in some

soils. Strong winds swept across the recently

deposited glacial material, which was largely devoid of

vegetation, and carried away large amounts of siltsized particles, which were later deposited as loess.

When the glacial ice retreated and the climate

gradually warmed, deciduous forests eventually

succeeded the boreal vegetation.

The county currently has a humid, temperate

climate, which has persisted for thousands of years. In

this climatic environment, physical and chemical

weathering of the parent material can occur along with

the accumulation of organic matter, the decomposition

of minerals, the formation and translocation of clay, the

leaching of soluble compounds, and alternating

periods of freezing and thawing.

The microclimate in a given area can affect soil

formation. Pierron soils, which are in depressions or

low-lying areas, receive runoff from the higher

adjacent slopes. The runoff creates a wet microclimate

that results in prolonged saturation, the reduction of

iron, and a gray subsoil.

Climate also influences the kind and extent of plant

and animal life. The climate in Randolph County has

favored prairie grasses and hardwood forests. Heavy

rains can harm exposed areas of soil that have been

farmed. Spring rains and wind can cause extensive

erosion when crop residue and trees are removed

from the surface. More soil may be lost through

erosion each year than is formed by natural

processes.

Living Organisms

The vegetation under which a soil forms influences

soil properties, such as color, structure, reaction, and

content and distribution of organic matter. Vegetation

extracts water from the soil, recycles nutrients, and

adds organic material to the soil. Gases derived from

root respiration combine with water to form acids that

influence the weathering of minerals. Because of the

lower content of organic matter, soils that formed

under forest vegetation are generally lighter colored

than those that formed under grasses.

At the time Randolph County was settled, the native

vegetation consisted mainly of hardwood forests.

Differences in natural soil drainage and minor

variations in the parent material have affected the

composition of the forest species.

Bacteria, fungi, and many other micro-organisms

decompose organic material and release nutrients to

growing plants. They also influence the formation of

peds, which are natural soil aggregates. Soil properties,

such as drainage, temperature, and reaction, influence

the type of micro-organisms that live in the soil. Fungi

are generally more active in the acid soils, and

bacteria are more active in the less acid soils.

Earthworms, insects, and small burrowing animals

mix the soil and create small channels that influence

soil aeration and the percolation of water. Earthworms

help to incorporate crop residue or other organic

material into the soil. The organic matter improves tilth.

In areas that are well populated with earthworms, the

leaf litter that accumulates on the soil in the fall is

generally incorporated into the soil by the following

spring. If the earthworm population is low, part of the

leaf litter can remain on the surface of the soil for

several years.

Human activities have significantly influenced soil

formation. Native forests have been cleared and

developed for farming and other uses. Cultivation has

accelerated erosion on sloping soils; wet soils have

been drained; and manure, lime, chemical fertilizer,

and pesticides have been applied in cultivated areas.

Cultivation has affected soil structure and compaction

and lowered the content of organic matter. The

development of land for urban uses or for mining has

significantly influenced the soils in some areas.

Relief

Relief, which includes elevation and topography,

influences soil formation through its effect on runoff

and erosion. To a lesser extent, it also influences soil

temperature, the plant cover, depth to the water table,

and the accumulation and removal of organic matter.
Randolph County, Illinois 21

Because it causes differences in external soil

drainage, relief can differentiate soils that formed in

the same kind of parent material. Water that runs off

the more sloping soils can collect in depressions or

swales. Ruma and Pierron soils both formed in loess.

The sloping to steep Ruma soils on convex summits

and side slopes are well drained. They are in areas

where external drainage is good. The nearly level

Pierron soils are poorly drained. They are in slight

depressions that receive runoff from higher adjacent

soils, and they have poor internal drainage.

Relief varies in Randolph County. On the ground

moraines in the eastern part of the county, the soils

generally range from nearly level on the interfluves to

moderately sloping along the drainageways. Relief

becomes more pronounced in the western part of the

county near the bluff. In the Mississippi River Valley,

relief is nearly level to gently undulating.

Time

The length of time that the parent material has been

exposed to soil-forming processes influences the

nature of the soil that forms. The youngest soils in the

county, such as Birds, Rocher, and Wakeland soils,

formed in recent alluvium. These soils can be stratified

and have weakly expressed horizons because the

soil-forming processes are interrupted with each new

deposition.

Glaciers advanced over much of Randolph County

during the Illinois Glaciation. Glacial deposits, in the

form of loess and alluvium, from the Wisconsinan

Glaciation were deposited many years later. Glacial

deposits of Wisconsinan age are geologically young,

yet enough time has elapsed for the initially raw parent

material to weather into soils that have distinct

horizons. In most of these soils, including Caseyville,

Menfro, and Winfield soils, carbonates have been

leached, clay has been translocated from the A

horizon to the B horizon, and organic matter has

accumulated in the A horizon.

Processes of Soil Formation

Soil forms through complex processes. These

processes can be grouped into four general

categories—additions, removals, transfers, and

transformations. All of these processes affect soil

formation, although in differing degrees.

The accumulation of organic matter in the A horizon

of the soils in Randolph County is an example of an

addition. This accumulation is the main reason for the

dark color of the A horizon. The color of the raw parent

material generally is uniform throughout.

The leaching of carbonates from the upper several

feet in many of the deep loess soils is an example of a

removal. The parent material of these soils was initially

calcareous, but the carbonates have been leached

from the soil profile by percolating water.

The translocation of clay from the A horizon to the B

horizon in many soils on uplands in the county is an

example of a transfer. The A horizon (or an E horizon)

is a zone of eluviation, or loss. The B horizon is a zone

of illuviation, or gain. In Marine, Winfield, and other

soils, the B horizon has more clay than the parent

material and the A horizon has less clay. In the B

horizon of some soils, faint to prominent clay films are

in pores and on faces of peds.

An example of a transformation is the reduction and

solubilization of ferrous iron. This process takes place

under wet, saturated conditions in which there is a

lack of molecular oxygen. Gleying, or the reduction of

iron, is evident in Darwin, Fults, and Pierron soils,

which have a dominantly gray subsoil. The gray color

indicates the presence of reduced ferrous iron, which,

in turn, implies wetness. Reduced iron is soluble, but it

commonly has been removed short distances in the

soils, stopping either in the horizon where it originated

or in an underlying horizon. Part of this iron can be

reoxidized and segregated in the form of stains,

masses, nodules, concretions, or bright yellow and red

concentrations.

Classification of the Soils

The system of soil classification used by the

National Cooperative Soil Survey has six categories

(Soil Survey Staff, 1999). 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.

Table 4 shows the classification of the soils in the

survey area. The categories are defined in the

following paragraphs.

ORDER. Twelve soil orders are recognized. The

differences among orders reflect the dominant soilforming 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 Aquoll

(Aqu, meaning water, plus oll, from Mollisol).

GREAT GROUP. Each suborder is divided into
22

great groups on the basis of close similarities in kind,

arrangement, and degree of development of

pedogenic horizons; soil moisture and temperature

regimes; type of saturation; and base status. Each

great group is identified by the name of a suborder

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

example is Endoaquolls (Endo, referring to

endosaturation, plus aquoll, the suborder of the

Mollisols that has an aquic moisture regime).

SUBGROUP. Each great group has a typic

subgroup. Other subgroups are intergrades or

extragrades. The typic subgroup is the central concept

of the great group; it is not necessarily the most

extensive. Intergrades are transitions to other orders,

suborders, or great groups. Extragrades have some

properties that are not representative of the great

group but do not indicate transitions to any other

known kind of soil. Each subgroup is identified by one

or more adjectives preceding the name of the great

group. An example is Fluvaquentic Vertic Endoaquolls.

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, mineral

content, soil temperature regime, thickness of the root

zone, consistence, moisture equivalent, and reaction.

A family name consists of the name of a subgroup

preceded by terms that indicate soil properties. An

example is fine, smectitic, mesic Fluvaquentic Vertic

Endoaquolls.

SERIES. The series consists of soils within a

family that have horizons similar in color, texture,

structure, reaction, consistence, mineral and

chemical composition, and arrangement in the profile.

The texture of the surface layer or of the substratum

can differ within a series. An example is the Darwin

series.
23

In this section, arranged in alphabetical order, each

soil series recognized in the survey area is described.

Each series description is followed by descriptions of

the associated detailed soil map units.

Characteristics of the soil and the material in which

it formed are identified for each soil series. A pedon, a

small three-dimensional area of soil, that 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” (Soil Survey Division Staff,

1993). Many of the technical terms used in the

descriptions are defined in “Soil Taxonomy” (Soil

Survey Staff, 1999) and in “Keys to Soil Taxonomy”

(Soil Survey Staff, 1998). Unless otherwise stated,

colors in the descriptions are for moist soil. Following

the pedon description is the range of important

characteristics of the soils in the series.

The map units on the detailed soil maps in this

survey represent the soils or miscellaneous areas in

the survey area. The map unit descriptions in this

section, along with the maps, can be used to

determine the suitability and potential of a unit for

specific uses. They also can be used to plan the

management needed for those uses. More information

about each map unit is given under the headings “Use

and Management of the Soils” and “Soil Properties.”

A map unit delineation on a soil map represents an

area dominated by one or more major kinds of soil or

miscellaneous areas. A map unit is identified and

named according to the taxonomic classification of the

dominant soils. Within a taxonomic class there are

precisely defined limits for the properties of the soils.

On the landscape, however, the soils 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, can be mapped

without including areas of other taxonomic classes.

Consequently, every map unit is made up of the soils

or miscellaneous areas for which it is named and

some minor components that belong to taxonomic

classes other than those of the major soils.

Most minor 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, components. They

may or may not be mentioned in a particular map unit

description. Other minor components, however, have

properties and behavioral characteristics divergent

enough to affect use or to require different

management. These are called contrasting, or

dissimilar, components. 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 contrasting

components are mentioned in the map unit

descriptions. A few areas of minor components 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 minor components 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 landforms or landform segments that

have similar use and management requirements. The

delineation of such segments on the map provides

sufficient information for the development of resource

plans. If intensive use of small areas is planned,

however, 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 some of the soil

properties and qualities that may affect 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, 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, slope, stoniness, salinity, degree of

erosion, and other characteristics that affect their use.

On the basis of such differences, a soil series is

divided into soil phases. Most of the areas shown on

Soil Series and Detailed Soil Map Units
24 Soil Survey of

the soil maps are phases of soil series. The name of a

soil phase commonly indicates a feature that affects

use or management. For example, Homen silt loam, 5

to 10 percent slopes, eroded, is a phase of the Homen

series.

Some map units are made up of two or more major

soils. These map units are called complexes. A

complex consists of two or more soils 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 are somewhat similar in all

areas. Neotoma-Wellston complex, 35 to 60 percent

slopes, is an example.

This survey includes miscellaneous areas. Such

areas have little or no soil material and support little or

no vegetation. The map unit Pits, quarries, is an

example.

Table 5 gives the acreage and proportionate extent

of each map unit. Other tables (see Contents) 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 forestland; as sites for buildings, sanitary facilities,

highways and other transportation systems, and parks

and other recreational facilities; and as 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.

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.

Interpretive Ratings

The interpretive tables in this survey rate the soils in

the survey area for various uses. Many of the tables

identify the limitations that affect specified uses and

indicate the severity of those limitations. The ratings in

these tables are both verbal and numerical.

Rating Class Terms

Rating classes are expressed in the tables in terms

that indicate the extent to which the soils are limited by

all of the soil features that affect a specified use or in

terms that indicate the suitability of the soils for the

use. Thus, the tables may show limitation classes or

suitability classes. Terms for the limitation classes are

not limited, somewhat limited, and very limited. The

suitability ratings are expressed as well suited,

moderately suited, poorly suited, and unsuited or as

good, fair, poor, and very poor.

Numerical Ratings

Numerical ratings in the tables indicate the relative

severity of individual limitations. The ratings are shown

as decimal fractions ranging from 0.00 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

and the point at which the soil feature is not a

limitation. The limitations appear in order from the

most limiting to the least limiting. Thus, if more than

one limitation is identified, the most severe limitation is

listed first and the least severe one is listed last.

Crops and Pasture

General management needed for crops and pasture

is suggested in this section. The estimated yields of

the main crops and pasture plants are listed, the

system of land capability classification used by the

Natural Resources Conservation Service is explained,

and prime farmland is described.

Planners of management systems for individual

fields or farms should consider the detailed

information given in the description of each soil under

the heading “Soil Series and Detailed Soil Map Units.”

Specific information can be obtained from the local

office of the Natural Resources Conservation Service

or the Cooperative Extension Service.

soybeans. This rotation allows the harvesting of two

cash crops each year. The soils in the county have

good potential for continued crop production,

especially if the latest crop production technology is

applied. This soil survey can be used as a guide for

applying the latest crop production technologies.

The demand for food and fiber has increased in

recent years. As a result, some land of marginal

quality has been used for crops. Much of this land is

more susceptible to erosion than the more productive

land. Also, the number of residential tracts has

increased in parts of the county. These tracts

commonly are in areas of prime farmland. If these

trends continue, they could result in a significant

decline in the quality and quantity of the land used for

food and fiber.

The major soil management concerns affecting

cropland in the county are water erosion, excessive

permeability, surface crusting, poor tilth, wetness,

ponding, restricted permeability, and droughtiness.

Erosion is a potential problem on approximately 70

percent of the cropland in the county. Erosion can be a

problem on soils that have slopes of more than 2

percent, such as Bunkum, Hickory, and Menfro soils.

Loss of the surface layer is damaging for several

reasons. Soil productivity is reduced as the surface

soil is removed and part of the subsoil is incorporated

into the plow layer. The subsoil is generally lower in

plant nutrients, lower in organic matter, and higher in

clay content compared to the surface soil. As the

content of organic matter decreases in the plow layer

and the content of clay increases, soil tilth

deteriorates, resulting in soil crusting and a reduced

rate of water infiltration. Erosion results in the

sedimentation of streams, rivers, road ditches, and

lakes. This pollution caused by sedimentation reduces

the quality of water for agriculture, for municipal and

recreational uses, and for fish and wildlife. Removing

the sediment generally is expensive. Controlling

erosion helps to minimize this pollution and improves

water quality.

Erosion-control measures include both cultural and

structural practices. The most widely used practice in

the county is a system of conservation tillage, such as

mulch tillage and zero tillage (fig. 5). These systems

can leave 30 to 90 percent of the surface covered with

crop residue. Another cultural practice is a crop

rotation that includes 1 or more years of close-growing

grasses or legumes. In areas where slopes are long

and uniform, terraces and contour farming also are

effective in controlling erosion (fig. 6).

Structural practices are needed in drainageways

where concentrated runoff flows overland. Erosion can

be controlled by establishing grassed waterways or

installing erosion-control structures.

Further information about erosion-control measures

suitable for each kind of soil is provided in the Field

Office Technical Guide, which is available in local

offices of the Natural Resources Conservation

Service.

Soils that have excessive permeability, such as

Bloomfield and Rocher soils, have the potential for

ground-water contamination. These soils contain

sandy deposits within a depth of 40 inches and are

very rapidly permeable in the lower part of the profile.

Several measures can be used to limit the amount

of deep leaching of nutrients and pesticides. On all

soils, applications of fertilizer should be based on the

results of soil tests. The local office of the Cooperative

Extension Service can help in determining the proper

kinds and amounts of nutrients to be used. Chemicals

should be selected according to their solubility in

water, their ability to bind with the soil, and the rate of

their breakdown in the soil. Splitting chemical

applications, particularly nitrogen, is beneficial. This

practice, rather than a one-time application, reduces

the chance for excessive leaching. Another measure is

planting legumes in a crop rotation or as a cover crop.

This practice adds nitrogen to the soil, thereby

reducing the amount of nitrogen needed in chemical

applications. The practice of crop rotation is also

effective in limiting the build-up of weed and insect

populations and thus reduces the amount of

herbicides and insecticides needed per application.

Finally, a rotation of small grain cover crops following

fertilized corn crops can be effective in taking up some

residual nitrogen from the soil.

Drainage systems have been installed in most

areas of poorly drained and somewhat poorly drained

soils used as cropland in the county. As a result, these

soils are adequately drained for the crops commonly

grown. Measures that maintain the drainage system

are needed. Poorly drained soils, such as Burksville,

Piasa, and Pierron soils, have subsurface drainage. In

addition, surface tile inlets or shallow surface ditches

are needed to remove excess water in some areas of

poorly drained soils. In some places, somewhat poorly

drained soils are wet long enough that in some years

productivity is reduced unless they are artificially

drained. Somewhat poorly drained soils, such as

Caseyville and Marine soils, have subsurface

drainage.

Soil tilth is an important factor influencing the

germination of seeds, the amount of runoff, and the

rate of water infiltration. Soils that have good tilth are
Randolph County, Illinois 133

granular and porous and have a high content of

organic matter.

Surface crusting can be a problem in areas of

Marine and Pierron soils. The surface layer in these

soils is silt loam and has a low content of organic

matter. Generally, the structure of these soils is weak,

and a crust forms on the surface during periods of

intense rainfall. This crust is hard when dry. It inhibits

seedling emergence, reduces the infiltration rate, and

increases runoff and erosion. Regular additions of

crop residue, manure, and other organic material

improve soil structure and minimize crusting.

Poor tilth is also a problem on soils that have a

surface layer of silty clay loam or silty clay. If poorly

drained soils, such as Booker and Fults soils, are

plowed when wet, the surface layer can become

cloddy. The cloddiness hinders the preparation of a

good seedbed. Tilling in the fall and leaving the soil

surface rough with moderate amounts of crop residue

generally result in good tilth in the spring. A system of

strip tillage or ridge tillage may also be effective on

these soils.

Restricted permeability in the soil can increase the

susceptibility to erosion. As water movement slows

within a soil, the rate of runoff increases. The slowly

permeable Colp soils are more susceptible to erosion

than the moderately permeable Winfield soils. The

effects of restricted permeability can be controlled by

applying a cropping system that leaves crop residue

on the surface after planting, incorporating green

manure crops or crop residue into the soil, and using

conservation cropping systems.

Restricted permeability can also limit the

effectiveness of drainage systems. In the very slowly

permeable Pierron soils, a narrower tile spacing is

needed than in the slowly permeable Burksville soils in

order to lower the water table effectively.

A low available water capacity limits the productivity

of some soils used for crops in the county. The

physical composition of such soils as Bloomfield and

Rocher soils limits the amount of water available for

plant growth. The effects of droughtiness can be

minimized by reducing the amount of runoff and

increasing the water-holding capacity of the soils.

Figure 5.—A field of no-till corn planted in wheat stubble in an area of Winfield soils.
134 Soil Survey of

Using a conservation tillage system and returning

crop residue and other organic material to the soil

help to overcome droughtiness. Planting such crops

as winter wheat can help to avoid the drought-prone

season. Also, irrigation helps to overcome

droughtiness.

Hay is a very important crop in the county for dairy

and beef production and for people who own small

acreages and have horses for recreational purposes.

There are some permanent hay and pasture fields in

the county, but most producers rotate their hay

seeding between 1 to several years of row crops, such

as corn and soybeans.

Proper management is needed on hayland to

maintain or improve the life of desirable forage

species, to maintain or improve the quality and

quantity of forage, and to control erosion and reduce

runoff. Hay may last as a vigorous crop for 4 or 5

years, depending on management and on the varieties

seeded. Suitable hay plants include several legumes

and grasses. Alfalfa is the most commonly grown

legume for hay. It is often used in mixtures with smooth

bromegrass and orchardgrass. Alfalfa is best suited to

well drained soils, such as Menfro and Ruma soils.

Red clover also is grown for hay. Measures that

maintain or improve fertility are needed. The amount of

lime and fertilizer to be added should be based on the

results of soil tests, the needs of the plants, and the

expected level of yields. Seed varieties should be

selected in accordance with the soil properties and the

drainage conditions of the tract of land.

Limitations Affecting Crops and Pasture

The management concerns affecting the use of the

detailed soil map units in the survey area for crops and

pasture are shown in table 6. The main concerns in

managing cropland are controlling water erosion, soil

wetness, and ponding; minimizing surface crusting;

improving poor tilth; and limiting the effects of

excessive permeability, restricted permeability, and

low available water capacity. The major management

concerns affecting pastureland are water erosion, soil

fertility, low available water capacity, low pH, and

equipment limitations.

Cropland

Generally, a combination of several practices is

needed to control water erosion. Conservation tillage,

stripcropping, contour farming, conservation cropping

systems, crop residue management, diversions, and

grassed waterways help to minimize excessive soil

loss.

Wetness is a limitation in some areas used as

cropland, and ponding is a hazard. Drainage systems

consist of subsurface tile drains, surface inlet tile, open

drainage ditches, or a combination of these. Measures

that maintain the drainage system are needed.

Practices that minimize surface crusting and

improve soil tilth include incorporating green manure

crops, manure, or crop residue into the soil and using

a system of conservation tillage. Surface cloddiness

can be controlled by avoiding tillage when the soil is

too wet.

Excessive permeability can cause deep leaching of

nutrients and pesticides. Selecting appropriate

chemicals and using split application methods reduce

the hazard of ground-water contamination.

Restricted permeability can be overcome by

incorporating green manure crops, manure, or crop

residue into the soil; applying a system of

conservation tillage; and using conservation cropping

systems.

Conserving moisture is important in areas where

the soils have a low available water capacity. It

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.

Some of the limitations and hazards shown in the

table cannot be easily overcome. These are flooding,

depth to bedrock, and subsidence.

Additional limitations and hazards are as follows:

Excess lime.—This limitation can be overcome by

incorporating green manure crops, manure, or crop

residue into the soil; applying a system of

conservation tillage; and using conservation cropping

Figure 6.—Terraces in a cultivated field north of the town of

Red Bud in an area of Bunkum-Atlas silty clay loams, 10

to 18 percent slopes, severely eroded.
Randolph County, Illinois 135

systems. Also, crops may respond well to additions of

phosphate fertilizer to soils that have a high content of

lime.

Depth to bedrock.—Rooting depth and available

moisture may be limited by bedrock within a depth of

30 inches.

Flooding.—Winter small grain crops can be

damaged. Tilling and planting should be delayed in the

spring until flooding is no longer a hazard.

Low pH or high pH.—Reaction can affect plant

growth by influencing the uptake or absorption of

certain nutrients by plants.

Subsidence.—Subsidence occurs as a result of

shrinkage from drying, consolidation because of the

loss of ground water, compaction from tillage, wind

erosion, burning, and biochemical oxidation. Limiting

the amount of drainage, avoiding excessive tillage and

tillage when the soil is wet, and using a system of

conservation tillage that leaves crop residue on the

surface after planting help to control subsidence.

Wind erosion.—Using a system of conservation

tillage that leaves crop residue on the surface after

planting and keeping the surface rough help to control

this hazard.

The criteria used to determine some of the

limitations or hazards in the table are described in the

following paragraphs.

Crusting.—The average content of organic matter in

the surface layer is less than 2.5 percent, and the clay

content is greater than 20 percent.

Depth to bedrock.—Bedrock is within a depth of 30

inches.

Excess lime.—The calcium carbonate equivalent is

15 percent or more, and the calcic horizon

classification criteria are met.

Excessive permeability.—The upper limit of the

permeability range is 6 inches or more within the soil

profile.

Flooding.—The soil is occasionally flooded or

frequently flooded.

Low available water capacity.—The weighted

average of the available water capacity between the

surface and a depth of 40 inches is 0.1 inch or less.

Low pH.—Soils that have low pH, or low reaction,

have a pH value equal to or less than 5.5 in the

surface layer.

High pH.—Soils that have high pH, or high reaction,

have a pH value equal to or more than 8.5 in the

surface layer.

Ponding.—A water table is above the surface.

Poor tilth.—The component of the map unit has 27

percent or more clay in the surface layer.

Restricted permeability.—Permeability is less than

0.2 inch per hour between the surface and a depth of

40 inches.

Subsidence.—The decrease in surface elevation is

more than 0 inches.

Water erosion.—The K factor of the surface layer

multiplied by the slope is greater than 0.8, and the

slope is 3 percent or more.

Wetness.—The component of the map unit has a

water table within a depth of 1.5 feet.

Wind erosion.—The wind erodibility group (WEG) is

1 or 2.

Pastureland

Growing legumes, cool-season grasses, and warmseason grasses that are suited to the soils and climate

of the area helps to maintain a productive stand of

pasture.

Pastureland soils that are susceptible to water

erosion meet the following criteria: The value of the K

factor multiplied by the slope is greater than 0.8, and

the slope is equal to or greater than 3 percent.

Water erosion reduces the productivity of

pastureland. It also results in onsite and offsite

sedimentation, causes water pollution by

sedimentation, and increases the runoff of livestock

manure and other added nutrients.

Measures that are effective in controlling water

erosion include establishing or renovating stands of

legumes and grasses. Controlling erosion during

seedbed preparation is a major concern. If the soil is

tilled for the reseeding of pasture or hay crops,

planting winter cover crops, establishing grassed

waterways, farming on the contour, and using a

system of conservation tillage that leaves a protective

cover of crop residue on the surface can help to

minimize erosion.

Overgrazing or grazing when the soil is wet reduces

the extent of plant cover and results in surface

compaction and poor tilth, and thus it increases the

susceptibility to erosion. Proper stocking rates, rotation

grazing, and timely deferment of grazing, especially

during wet periods, help to keep the pasture in good

condition. The proper location of livestock watering

facilities helps to minimize surface compaction or the

formation of ruts by making it unnecessary for cattle to

travel long distances up and down the steep slopes.

Soils that have low fertility meet the following

criteria: The average content of organic matter in the

surface layer is less than 1 percent, and the cationexchange capacity is equal to or less than 7

milliequivalents per 100 grams of soil.

Low fertility levels affect the health and vigor of the

plants and thus have a direct impact on the quantity
136 Soil Survey of

and quality of livestock produced. Additions of

fertilizers and other organic material should be based

on the results of soil tests, on the needs of specific

plant species, and on the desired level of production.

Soils that have low pH, or low reaction, have a pH

value equal to or less than 5.5 in the surface layer.

Soils that have high pH have a pH value equal to or

more than 8.5 in the surface layer.

Low or high pH inhibits the uptake of certain

nutrients by the plants or accelerates the absorption of

certain other elements to the level of toxic

concentrations. Either of these conditions affects the

health and vigor of plants. Applications of lime should

be based on the results of soil tests. The goal is to

achieve the optimum pH level for the uptake of the

major nutrients by the specific grass, legume, or

combination of grasses and legumes.

Available water capacity is low when it is a weighted

average of less than 0.10 inch of water per inch of soil

within a depth of 40 inches or when it is a weighted

average of less than 3 inches in the root zone if the

root zone is less than 40 inches thick. Available water

capacity refers to the capacity of soils to hold water

available for use by most plants. The quality and

quantity of pasture may be reduced if the available

water is inadequate for the maintenance of a healthy

community of desired pasture species and thus the

desired number of livestock. A poor quality pasture

may increase the hazard of erosion and increase the

runoff of pollutants. Planting drought-resistant species

of grasses and legumes helps to establish a cover of

vegetation. Irrigation may be needed.

In areas where slopes are 10 percent or more, the

use of farm equipment may be restricted.

In areas where the soils have more than 15 percent

gravel in the surface layer, seedbed preparation and

renovation practices may be hindered. The cobbles

and stones can be removed or piled in a corner of the

field.

Crop Yield Estimates

The average yields per acre that can be expected

of the principal crops under a high level of

management are shown in table 7. In any given year,

yields may be higher or lower than those indicated in

the table because of variations in rainfall and other

climatic factors. The land capability classification of the

soils also is shown in the table.

The yields are based mainly on the experience and

records of farmers, conservationists, and extension

agents (Fehrenbacher and others, 1978; Olson and

Lang, 1994). Available yield data from nearby counties

and results of field trials and demonstrations also are

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; 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 relative productivity of a given soil

compared with that of other soils, however, is not likely

to change.

Crops other than those shown in the table are

grown in the survey area, but estimated yields are not

listed because the acreage of such crops is small. The

local office of the Natural Resources Conservation

Service or of the Cooperative Extension Service can

provide information about the management and

productivity of the soils for those crops.

Pasture yields.—Under good management, proper

grazing is essential for the production of high-quality

forage, stand survival, and erosion control. Proper

grazing helps plants to maintain sufficient and

generally vigorous top growth during the growing

season. Brush control is essential in many areas, and

weed control generally is needed. Rotation grazing

and renovation also are important management

practices.

Yield estimates are often provided 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 table 7.

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
Randolph County, Illinois 137

criteria used in grouping the soils do not take into

account major and generally expensive landshaping

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 forestland or for

engineering purposes.

In the capability system, soils generally are grouped

at three levels—capability class, subclass, and unit

(USDA, 1961). These categories indicate the degree

and kinds of limitations affecting mechanized farming

systems that produce the more commonly grown field

crops, such as corn, soybeans, small grain, and hay.

Only class and subclass are used in this survey.

Capability classes, the broadest groups, are

designated by the numbers 1 through 8. The numbers

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

forestland. 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

Cooperative Extension Service or the Natural

Resources Conservation Service can provide

guidance on the use of these soils as cropland.

Areas in class 8 are generally not suited to crops,

pasture, or forestland without a level of management

that is impractical. 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 to pasture, forestland, wildlife habitat, or

recreation.

The capability classification of the soils in the

survey area is given in table 7.

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, should 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 resource, and

farming these soils results in the least damage to the

environment.

Prime farmland soils may presently be used as

cropland, pasture, or forestland 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
138 Soil Survey of

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

mainly from 0 to 6 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 169,440 acres in the survey area, or nearly

44 percent of the total acreage, meets the soil

requirements for prime farmland. Areas of this land are

throughout the county. The prime farmland is generally

used for crops, mainly corn, soybeans, and wheat,

which account for most of the local farm income.

The map units in the survey area that meet the

criteria for prime farmland are listed in table 8. This list

does not constitute a recommendation for a particular

land use. On some soils included in the table,

measures that overcome limitations are needed. The

need for these measures is indicated in parentheses

after the map unit name. 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 “Soil Series and Detailed Soil Map Units.”

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. The erosion factors for the soils in the

survey area are listed in table 20.

Soil Erodibility (Kw) Factor

The soil erodibility (Kw) factor indicates the

susceptibility of a soil to sheet and rill erosion by

water. 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.

Fragment-Free Soil Erodibility (Kf) Factor

This is one of the factors used in the Revised

Universal Soil Loss Equation (RUSLE). It shows the

erodibility of the fine-earth fraction, or the material less

than 2 millimeters in size.

Soil-Loss Tolerance (T) Factor

The soil-loss tolerance (T) factor is an estimate of

the maximum annual rate of soil erosion 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 (I) factor is determined. This

factor is an expression of the stability of the soil

aggregates, or the extent to which they are broken

down by tillage and the abrasion caused by windblown

soil particles. Soils are assigned to wind erodibility

groups (WEG) having similar percentages of dry soil

aggregates larger than 0.84 millimeter. The wind

erodibility groups and wind erodibility index numbers

are listed in table 20.

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.

Forestland Management and

Productivity

Randolph County was originally mostly forestland.

The steep uplands were dominated by oak and

hickory; the nearly level uplands supported elm, black

walnut, hackberry, wild cherry, and honeylocust; and

the flood plains supported cottonwood, sycamore,

black walnut, white walnut, ash, elm, pecan, soft

maple, and persimmon. Settlers cleared some of the

forests for farms, homesteads, and fuel. An increase in

the population and the development of new farming
Randolph County, Illinois 139

technology during the latter part of the 19th century

resulted in a large decline in the acreage used as

forestland. The demand for agricultural production

during the 20th century and urban expansion have

accelerated this decline. Much of the remaining

forestland is in areas that are too steep or too wet for

cultivation. The soils in these areas have fair or good

potential for trees of high quality if the forestland is

properly managed.

Most of the remaining areas of forestland in

Randolph County are privately owned. The largest

areas are on the deeply dissected uplands near the

bluff. The main species on uplands are white oak,

northern red oak, and shagbark hickory, and the main

species on the flood plains are eastern cottonwood

and American sycamore.

Many of the stands can be improved by measures

that thin out mature trees and remove undesirable

species. Measures that exclude livestock, prevent

fires, and control disease and insects also are needed.

Assistance in establishing, improving, or managing

forestland is available from foresters or natural

resource specialists.

Table 9 provides information regarding the

productivity of the soils in the county for forestland.

The potential productivity for merchantable or common

trees on a soil is expressed as a site index and as a

volume number. Only those soils suitable for wood

crops are listed.

The site index is the average height, in feet, that

dominant and codominant trees of a given species

attain in a specified number of years. The site index

applies to fully stocked, even-aged, unmanaged

stands.

In most cases, the first species listed under

common trees for a soil is the indicator species for that

soil. It generally is the most common species on the

soil. Commonly grown trees are those that forest

managers generally favor in intermediate or

improvement cuttings. They are selected based on

growth rate, quality, value, and marketability.

The volume of wood fiber, a number, is the yield

likely to be produced by the most important trees. This

number, expressed as cubic feet per acre per year

and calculated at the age of culmination of the mean

annual increment (CMAI), indicates the amount of

fiber produced in a fully stocked, even-aged,

unmanaged stand.

Trees to manage are those that are preferred for

planting, seeding, or natural regeneration and those

that remain in the stand after thinning or partial

harvest.

In tables 10a, 10b, 10c, 10d, and 10e, interpretive

ratings are given for various aspects of forest

management. The ratings are both verbal and

numerical.

Some rating class terms indicate the degree to

which the soils are suited to a specified forest

management practice. Well suited indicates that the

soil has features that are favorable for the specified

practice and has no limitations. Good performance can

be expected, and little or no maintenance is needed.

Moderately suited indicates that the soil has features

that are moderately favorable for the specified practice.

One or more soil properties are less than desirable,

and fair performance can be expected. Some

maintenance is needed. Poorly suited indicates that

the soil has one or more properties that are

unfavorable for the specified practice. Overcoming the

unfavorable properties requires special design, extra

maintenance, and costly alteration. Unsuited indicates

that the expected performance of the soil is

unacceptable for the specified practice or that extreme

measures are needed to overcome the undesirable

soil properties.

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

specified forest management practice (1.00) and the

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

Rating class terms for seedling mortality are

expressed as low, moderate, and high. Where these

terms are used, the numerical ratings indicate

gradations between the point at which the potential for

seedling mortality is highest (1.00) and the point at

which the potential is lowest (0.00).

The paragraphs that follow indicate the soil

properties considered in rating the soils for forest

management practices. More detailed information

about the criteria used in the ratings is available in the

“National Forestry Manual,” which is available in local

offices of the Natural Resources Conservation Service

or on the Internet.

For limitations affecting construction of haul roads

and log landings, the ratings are based on slope,

flooding, permafrost, plasticity index, the hazard of soil

slippage, content of sand, the Unified classification,

rock fragments on or below the surface, depth to a

restrictive layer that is indurated, depth to a water

table, and ponding. The limitations are described as

slight, moderate, or severe. A rating of slight indicates

that no significant limitations affect construction

activities, moderate indicates that one or more

limitations can cause some difficulty in construction,

and severe indicates that one or more limitations can

make construction very difficult or very costly.
140 Soil Survey of

The ratings of suitability for log landings are based

on slope, rock fragments on the surface, plasticity

index, content of sand, the Unified classification, depth

to a water table, ponding, flooding, and the hazard of

soil slippage. The soils are described as well suited,

moderately suited, or poorly suited to use as log

landings.

Ratings in the column soil rutting hazard are based

on depth to a water table, rock fragments on or below

the surface, the Unified classification, depth to a

restrictive layer, and slope. Ruts form as a result of the

operation of forest equipment. The hazard is described

as slight, moderate, or severe. A rating of slight

indicates that the soil is subject to little or no rutting,

moderate indicates that rutting is likely, and severe

indicates that ruts form readily.

Ratings in the column hazard of off-road or off-trail

erosion are based on slope and on soil erodibility

factor K. The soil loss is caused by sheet or rill erosion

in off-road or off-trail areas where 50 to 75 percent of

the surface has been exposed by logging, grazing,

mining, or other kinds of disturbance. The hazard is

described as slight, moderate, severe, or very severe.

A rating of slight indicates that erosion is unlikely

under ordinary climatic conditions; moderate indicates

that some erosion is likely and that erosion-control

measures may be needed; severe indicates that

erosion is very likely and that erosion-control

measures, including revegetation of bare areas, are

advised; and very severe indicates that significant

erosion is expected, loss of soil productivity and offsite damage are likely, and erosion-control measures

are costly and generally impractical.

Ratings in the column hazard of erosion on roads

and trails are based on the soil erodibility factor K,

slope, and content of rock fragments. The ratings

apply to unsurfaced roads and trails. The hazard is

described as slight, moderate, or severe. A rating of

slight indicates that little or no erosion is likely;

moderate indicates that some erosion is likely, that the

roads or trails may require occasional maintenance,

and that simple erosion-control measures are needed;

and severe indicates that significant erosion is

expected, that the roads or trails require frequent

maintenance, and that costly erosion-control

measures are needed.

Ratings in the column suitability for roads (natural

surface) are based on slope, rock fragments on the

surface, plasticity index, content of sand, the Unified

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

and the hazard of soil slippage. The ratings indicate

the suitability for using the natural surface of the soil

for roads. The soils are described as well suited,

moderately suited, or poorly suited to this use.

Ratings in the columns suitability for hand planting

and suitability for mechanical planting are based on

slope, depth to a restrictive layer, content of sand,

plasticity index, rock fragments on or below the

surface, depth to a water table, and ponding. The soils

are described as well suited, moderately suited, poorly

suited, or unsuited to these methods of planting. It is

assumed that necessary site preparation is completed

before seedlings are planted.

Ratings in the column suitability for use of

harvesting equipment are based on slope, rock

fragments on the surface, plasticity index, content of

sand, the Unified classification, depth to a water table,

and ponding. The soils are described as well suited,

moderately suited, or poorly suited to this use.

Ratings in the column suitability for mechanical site

preparation (surface) are based on slope, depth to a

restrictive layer, plasticity index, rock fragments on or

below the surface, depth to a water table, and ponding.

The soils are described as well suited, poorly suited,

or unsuited to this management activity. The part of

the soil from the surface to a depth of about 1 foot is

considered in the ratings.

Ratings in the column suitability for mechanical site

preparation (deep) are based on slope, depth to a

restrictive layer, rock fragments on or below the

surface, depth to a water table, and ponding. The soils

are described as well suited, poorly suited, or unsuited

to this management activity. The part of the soil from

the surface to a depth of about 3 feet is considered in

the ratings.

Ratings in the column potential for seedling

mortality are based on flooding, ponding, depth to a

water table, content of lime, reaction, salinity, available

water capacity, soil moisture regime, soil temperature

regime, aspect, and slope. The soils are described as

having a low, moderate, or high potential for seedling

mortality.

Windbreaks and Environmental

Plantings

Windbreaks protect livestock, buildings, yards, fruit

trees, gardens, and cropland from wind and snow;

help to keep snow on fields; and provide food and

cover for wildlife. 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.

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
Randolph County, Illinois 141

stock of suitable species should be planted properly

on a well prepared site and maintained in good

condition.

Table 11 shows the height that locally grown trees

and shrubs are expected to reach in 20 years on

various soils. The estimates in table 11 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 of

the Cooperative Extension Service or from a

commercial nursery.

Recreation

The demand for land and facilities for boating,

swimming, picnicking, fishing, hunting, hiking,

camping, and other forms of outdoor recreation is

increasing throughout the county. Facilities for these

activities are available on a few privately owned tracts.

The potential for further recreational development is

favorable throughout the county. The soils having the

best potential are along the Mississippi River. The

large areas of steep slopes along the bluffs provide a

natural setting for the establishment of paths and trails,

camp areas, and picnic areas.

The soils of the survey area are rated in tables 12a

and 12b according to limitations that affect their

suitability for recreation. 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.

The ratings in the tables are based on restrictive

soil features, such as wetness, slope, and texture of

the surface layer. Susceptibility to flooding is

considered. Not considered in the ratings, but

important in evaluating a site, are the location and

accessibility of the area, the size and shape of the

area and its scenic quality, vegetation, access to

water, potential water impoundment sites, and access

to public sewer lines. The capacity of the soil to absorb

septic tank effluent and the ability of the soil to support

vegetation also are important. Soils that are subject to

flooding are limited for recreational uses by the

duration and intensity of flooding and the season when

flooding occurs. In planning recreational facilities,

onsite assessment of the height, duration, intensity,

and frequency of flooding is essential.

The information in the tables can be supplemented

by other information in this survey, for example,

interpretations for building site development,

construction materials, sanitary facilities, and water

management.

Camp areas require site preparation, such as

shaping and leveling the tent and parking areas,

stabilizing roads and intensively used areas, and

installing sanitary facilities and utility lines. Camp

areas are subject to heavy foot traffic and some

vehicular traffic. The ratings are based on the soil

properties that affect the ease of developing camp

areas and the performance of the areas after

development. Slope, stoniness, and depth to bedrock

or a cemented pan are the main concerns affecting

the development of camp areas. The soil properties

that affect the performance of the areas after

development are those that influence trafficability and

promote the growth of vegetation, especially in heavily

used areas. For good trafficability, the surface of camp

areas should absorb rainfall readily, remain firm under

heavy foot traffic, and not be dusty when dry. The soil

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Picnic areas are subject to heavy foot traffic. Most

vehicular traffic is confined to access roads and

parking areas. The ratings are based on the soil

properties that affect the ease of developing picnic

areas and that influence trafficability and the growth of

vegetation after development. Slope and stoniness are

the main concerns affecting the development of picnic

areas. For good trafficability, the surface of picnic

areas should absorb rainfall readily, remain firm under

heavy foot traffic, and not be dusty when dry. The soil

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.
142 Soil Survey of

Playgrounds require soils that are nearly level, are

free of stones, and can withstand intensive foot traffic.

The ratings are based on the soil properties that affect

the ease of developing playgrounds and that influence

trafficability and the growth of vegetation after

development. Slope and stoniness are the main

concerns affecting the development of playgrounds.

For good trafficability, the surface of the playgrounds

should absorb rainfall readily, remain firm under heavy

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Paths and trails for hiking and horseback riding

should require little or no slope modification through

cutting and filling. The ratings are based on the soil

properties that affect trafficability and erodibility. These

properties are stoniness, depth to a water table,

ponding, flooding, slope, and texture of the surface

layer.

Off-road motorcycle trails require little or no site

preparation. They are not covered with surfacing

material or vegetation. Considerable compaction of the

soil material is likely. The ratings are based on the soil

properties that influence erodibility, trafficability,

dustiness, and the ease of revegetation. These

properties are stoniness, slope, depth to a water table,

ponding, flooding, and texture of the surface layer.

Golf fairways are subject to heavy foot traffic and

some light vehicular traffic. Cutting or filling may be

required. Irrigation is not considered in the ratings. The

ratings are based on the soil properties that affect

plant growth and trafficability after vegetation is

established. The properties that affect plant growth are

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

bedrock or a cemented pan; the available water

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

sodium, or calcium carbonate; and sulfidic materials.

The properties that affect trafficability are flooding,

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

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

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

roughs, and greens is not considered in the ratings.

Wildlife Habitat

In general, most of the land in Randolph County is

not managed primarily for wildlife habitat. Good land

management practices, however, can improve the

value of many areas for wildlife. Farm practices that

leave crop residue on the fields during fall and winter

not only help to control erosion but also provide winter

cover and food for some species of wildlife. Allowing

grassed waterways, road ditches, fencelines, set-aside

fields, and vacant properties to remain unmowed until

early August can provide much-needed habitat for

ground-nesting wildlife, such as rabbits, pheasants,

and many species of songbirds.

Many temporarily and seasonally flooded wetlands

have been impacted by land use practices.

Development and cultivation in these wetlands should

be avoided. Buffer strips surrounding wetland areas

provide food and nesting cover for many wildlife

species and prevent these areas from filling in with

eroded sediment. Wetlands, streambanks, and

woodlots should be fenced so that wildlife are

excluded. Fencing protects and maintains the native

plant communities that support wildlife species, helps

to control erosion, and improves water quality.

When an area is being restored or managed for

wildlife habitat, an understanding of the soils on the

site is important. Poorly drained or very poorly drained

soils, for example, have a seasonal high water table

and are likely to support vegetation tolerant of wet

conditions. This kind of vegetation attracts wetland

wildlife species. In some areas, poorly drained and

very poorly drained soils have been drained by

subsurface tile drains or drainage ditches. Such areas

offer opportunities for the restoration of wetland

habitat, as long as negative impacts on neighboring

properties can be avoided.

Upland soils support plant communities that were

once dominated by prairie grasses and oak savannah

habitats. These habitats can be restored by applying

management practices that promote or reestablish the

native plant species and control or eliminate

competing exotic vegetation.

Assistance with wildlife habitat projects is available

from various local, State, and Federal agencies,

including the Illinois Department of Conservation, the

U.S. Fish and Wildlife Service, the Natural Resources

Conservation Service, and the local Soil and Water

Conservation District.

Soils affect the kind and amount of vegetation that

is available to wildlife as food and cover. They also

affect the construction of water impoundments. The

kind and abundance of wildlife depend largely on the

amount and distribution of food, cover, and water.

Wildlife habitat can be created or improved by planting

appropriate vegetation, by maintaining the existing

plant cover, or by promoting the natural establishment

of desirable plants.

In table 13, the soils in the survey area are rated

according to their potential for providing habitat for

various kinds of wildlife. This information can be used
Randolph County, Illinois 143

in planning parks, wildlife refuges, nature study areas,

and other developments for wildlife; in selecting soils

that are suitable for establishing, improving, or

maintaining specific elements of wildlife habitat; and in

determining the intensity of management needed for

each element of the habitat.

The potential of the soil is rated good, fair, poor, or

very poor. A rating of good indicates that the element

or kind of habitat is easily established, improved, or

maintained. Few or no limitations affect management,

and satisfactory results can be expected. A rating of

fair indicates that the element or kind of habitat can be

established, improved, or maintained in most places.

Moderately intensive management is required for

satisfactory results. A rating of poor indicates that

limitations are severe for the designated element or

kind of habitat. Habitat can be created, improved, or

maintained in most places, but management is difficult

and must be intensive. A rating of very poor indicates

that restrictions for the element or kind of habitat are

very severe and that unsatisfactory results can be

expected. Creating, improving, or maintaining habitat

is impractical or impossible.

The elements of wildlife habitat are described in the

following paragraphs.

Grain and seed crops are domestic grains and

seed-producing herbaceous plants. Soil properties

and features that affect the growth of grain and seed

crops are depth of the root zone, texture of the surface

layer, available water capacity, wetness, slope, surface

stoniness, and flooding. Soil temperature and soil

moisture also are considerations. Examples of grain

and seed crops are wheat, rye, oats, and barley.

Grasses and legumes are domestic perennial

grasses and herbaceous legumes. Soil properties and

features that affect the growth of grasses and legumes

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

available water capacity, wetness, surface stoniness,

flooding, and slope. Soil temperature and soil moisture

also are considerations. Examples of grasses and

legumes are fescue, lovegrass, bromegrass, clover,

and alfalfa.

Wild herbaceous plants are native or naturally

established grasses and forbs, including weeds. Soil

properties and features that affect the growth of these

plants are depth of the root zone, texture of the

surface layer, available water capacity, wetness,

surface stoniness, and flooding. Soil temperature and

soil moisture also are considerations. Examples of wild

herbaceous plants are bluestem, indiangrass,

blueberry, goldenrod, lambsquarter, dandelions,

blackberry, beggarweed, wheatgrass, and nightshade.

Hardwood trees and woody understory produce

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

foliage. Soil properties and features that affect the

growth of hardwood trees and shrubs are depth of the

root zone, available water capacity, and wetness.

Examples of these plants are oak, poplar, box elder,

birch, maple, green ash, willow, and hickory. Examples

of fruit-producing shrubs that are suitable for planting

on soils rated good are hawthorn, honeysuckle,

American plum, redosier dogwood, chokecherry,

serviceberry, silver buffaloberry, and crabapple.

Coniferous plants furnish browse and seeds. Soil

properties and features that affect the growth of

coniferous trees, shrubs, and ground cover are depth

of the root zone, available water capacity, and

wetness. Examples of coniferous plants are pine,

spruce, hemlock, fir, yew, cedar, larch, and juniper.

Wetland plants are annual and perennial wild

herbaceous plants that grow on moist or wet sites.

Submerged or floating aquatic plants are excluded.

Soil properties and features affecting wetland plants

are texture of the surface layer, wetness, reaction,

salinity, slope, and surface stoniness. Examples of

wetland plants are smartweed, wild millet, wildrice,

saltgrass, cordgrass, rushes, sedges, and reeds.

Shallow water areas have an average depth of less

than 5 feet. Some are naturally wet areas. Others are

created by dams, levees, or other water-control

structures. Soil properties and features affecting

shallow water areas are depth to bedrock, wetness,

surface stoniness, slope, and permeability. Examples

of shallow water areas are muskrat marshes,

waterfowl feeding areas, beaver ponds, and other

ponds.

The habitat for various kinds of wildlife is described

in the following paragraphs.

Habitat for openland wildlife consists of cropland,

pasture, meadows, and areas that are overgrown with

grasses, herbs, shrubs, and vines. These areas

produce grain and seed crops, grasses and legumes,

and wild herbaceous plants. Wildlife attracted to

these areas include bobwhite quail, pheasant,

meadowlark, field sparrow, killdeer, cottontail rabbit,

and red fox.

Habitat for woodland wildlife consists of areas of

deciduous and/or coniferous plants and associated

grasses, legumes, and wild herbaceous plants. Wildlife

attracted to these areas include wild turkey, owls,

thrushes, woodpeckers, tree squirrels, raccoon, and

deer.

Habitat for wetland wildlife consists of open, marshy

or swampy shallow water areas. Some of the wildlife

attracted to such areas are ducks, geese, herons,

shore birds, muskrat, mink, and beaver.
144 Soil Survey of

Hydric Soils

In this section, hydric soils are defined and

described and the hydric soils in the survey area are

listed.

The three essential characteristics of wetlands are

hydrophytic vegetation, hydric soils, and wetland

hydrology (Cowardin and others, 1979; U.S. Army

Corps of Engineers, 1987; National Research Council,

1995; Tiner, 1985). Criteria for each of the

characteristics must be met for areas to be identified

as wetlands. Undrained hydric soils that have natural

vegetation should support a dominant population of

ecological wetland plant species. Hydric soils that

have been converted to other uses should be capable

of being restored to wetlands.

Hydric soils are defined by the National Technical

Committee for Hydric Soils (NTCHS) as soils that

formed under conditions of saturation, flooding, or

ponding long enough during the growing season to

develop anaerobic conditions in the upper part

(Federal Register, 1994). These soils are either

saturated or inundated long enough during the

growing season to support the growth and

reproduction of hydrophytic vegetation.

The NTCHS definition identifies general soil

properties that are associated with wetness. In order

to determine whether a specific soil is a hydric soil or

nonhydric soil, however, more specific information,

such as information about the depth and duration of

the water table, is needed. Thus, criteria that identify

those estimated soil properties unique to hydric soils

have been established (Federal Register, 1995). These

criteria are used to identify a phase of a soil series

that normally is associated with wetlands. The criteria

used are selected estimated soil properties that are

described in “Soil Taxonomy” (Soil Survey Staff, 1999)

and “Keys to Soil Taxonomy” (Soil Survey Staff, 1998)

and in the “Soil Survey Manual” (Soil Survey Division

Staff, 1993).

If soils are wet enough for a long enough period to

be considered hydric, they should exhibit certain

properties that can be easily observed in the field.

These visible properties are indicators of hydric soils.

The indicators used to make onsite determinations of

hydric soils in this survey area are specified in “Field

Indicators of Hydric Soils in the United States” (Hurt

and others, 1998).

Hydric soils are identified by examining and

describing the soil to a depth of about 20 inches. This

depth may be greater if determination of an

appropriate indicator so requires. It is always

recommended that soils be excavated and described

to the depth necessary for an understanding of the

redoximorphic processes. Then, using the completed

soil descriptions, soil scientists can compare the soil

features required by each indicator and specify which

indicators have been matched with the conditions

observed in the soil. The soil can be identified as a

hydric soil if at least one of the approved indicators is

present.

The following map units meet the definition of hydric

soils and, in addition, have at least one of the hydric

soil indicators. This list can help in planning land uses;

however, onsite investigation is recommended to

determine the hydric soils on a specific site (National

Research Council, 1995; Hurt and others, 1998).

Map units that are made up of hydric soils may

have small areas, or inclusions, of nonhydric soils in

the higher positions on the landform, and map units

made up of nonhydric soils may have inclusions of

hydric soils in the lower positions on the landform.

Table 14 lists the hydric characteristics of the soils

in Randolph County. It identifies hydric soils and also

nonhydric soils that may have hydric inclusions. This

information can help in planning land uses on a

specific site; however, onsite investigation is

recommended to determine whether hydric soils occur

and the location of the included hydric soils (National

Research Council, 1995; Hurt and others, 1998).
Randolph County, Illinois 145

Engineering

This section provides information for planning land

uses related to urban development and to water

management. Soils are rated for various uses, and the

most limiting features are identified. Ratings are given

for building site development, sanitary facilities,

construction materials, and water management. The

ratings are based on observed performance of the

soils and on the data in the tables described under the

heading “Soil Properties.”

Information in this section is intended for land use

planning, for evaluating land use alternatives, and for

planning site investigations prior to design and

construction. The information, however, has limitations.

For example, estimates and other data generally apply

only to that part of the soil between the surface and a

depth of 5 to 7 feet. Because of the map scale, small

areas of different soils may be included within the

mapped areas of a specific soil.

The information is not site specific and does not

eliminate the need for onsite investigation of the soils

or for testing and analysis by personnel experienced in

the design and construction of engineering works.

Government ordinances and regulations that

restrict certain land uses or impose specific design

criteria were not considered in preparing the

information in this section. Local ordinances and

regulations should be considered in planning, in site

selection, and in design.

Soil properties, site features, and observed

performance were considered in determining the

ratings in this section. During the fieldwork for this soil

survey, determinations were made about particle-size

distribution, liquid limit, plasticity index, soil reaction,

depth to bedrock, hardness of bedrock within 5 to 7

feet of the surface, soil wetness, depth to a water

table, ponding, slope, likelihood of flooding, natural soil

structure aggregation, and soil density. Data were

collected about kinds of clay minerals, mineralogy of

the sand and silt fractions, and the kinds of adsorbed

cations. Estimates were made for erodibility,

permeability, corrosivity, shrink-swell potential,

available water capacity, and other behavioral

characteristics affecting engineering uses.

This information can be used to evaluate the

potential of areas for residential, commercial,

industrial, and recreational uses; make preliminary

estimates of construction conditions; evaluate

alternative routes for roads, streets, highways,

pipelines, and underground cables; evaluate

alternative sites for sanitary landfills, septic tank

absorption fields, and sewage lagoons; plan detailed

onsite investigations of soils and geology; locate

potential sources of gravel, sand, earthfill, and topsoil;

plan drainage systems, irrigation systems, ponds,

terraces, and other structures for soil and water

conservation; and predict performance of proposed

small structures and pavements by comparing the

performance of existing similar structures on the same

or similar soils.

The information in the tables, along with the soil

maps, the soil descriptions, and other data provided in

this survey, can be used to make additional

interpretations.

Some of the terms used in this soil survey have a

special meaning in soil science and are defined in the

Glossary.

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. Tables 15a and

15b 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
146 Soil Survey of

of 2 feet or at the depth of maximum frost penetration,

whichever is deeper. For dwellings with basements,

the foundation is assumed to consist of spread

footings of reinforced concrete built on undisturbed soil

at a depth of about 7 feet. The ratings for dwellings are

based on the soil properties that affect the capacity of

the soil to support a load without movement and on

the properties that affect excavation and construction

costs. The properties that affect the load-supporting

capacity include depth to a water table, ponding,

flooding, subsidence, linear extensibility (shrink-swell

potential), and compressibility. Compressibility is

inferred from the Unified classification. The properties

that affect the ease and amount of excavation include

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

to bedrock or a cemented pan, hardness of bedrock or

a cemented pan, and the amount and size of rock

fragments.

Small commercial buildings are structures that are

less than three stories high and do not have

basements. The foundation is assumed to consist of

spread footings of reinforced concrete built on

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

maximum frost penetration, whichever is deeper. The

ratings are based on the soil properties that affect the

capacity of the soil to support a load without

movement and on the properties that affect excavation

and construction costs. The properties that affect the

load-supporting capacity include depth to a water

table, ponding, flooding, subsidence, linear

extensibility (shrink-swell potential), and

compressibility (which is inferred from the Unified

classification). The properties that affect the ease and

amount of excavation include flooding, depth to a

water table, ponding, slope, depth to bedrock or a

cemented pan, hardness of bedrock or a cemented

pan, and the amount and size of rock fragments.

Local roads and streets have an all-weather surface

and carry automobile and light truck traffic all year.

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

of gravel, crushed rock, or soil material stabilized by

lime or cement; and a surface of flexible material

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

binder. The ratings are based on the soil properties

that affect the ease of excavation and grading and the

traffic-supporting capacity. The properties that affect

the ease of excavation and 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 (shrinkswell 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.

Sanitary Facilities

Tables 16a and 16b show the degree and kind of

soil limitations that affect septic tank absorption fields,

sewage lagoons, sanitary landfills, and daily cover for

landfill. Rating class terms indicate the extent to which

the soils are limited by all of the soil features that affect

these uses. Not limited indicates that the soil has

features that are very favorable for the specified use.

Good performance and very low maintenance can be

expected. Somewhat limited indicates that the soil has

features that are moderately favorable for the specified

use. The limitations can be overcome or minimized by

special planning, design, or installation. Fair

performance and moderate maintenance can be

expected. Very limited indicates that the soil has one

or more 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.

Septic tank absorption fields are areas in which
Randolph County, Illinois 147

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. Groundwater contamination is also a hazard if fractured

bedrock is within a depth of 40 inches, if the water

table is high enough to raise the level of sewage in the

lagoon, or if floodwater overtops the lagoon.

A high content of organic matter is detrimental to

proper functioning of the lagoon because it inhibits

aerobic activity. Slope, bedrock, and cemented pans

can cause construction problems, and large stones

can hinder compaction of the lagoon floor. If the

lagoon is to be uniformly deep throughout, the slope

must be gentle enough and the soil material must be

thick enough over bedrock or a cemented pan to make

land smoothing practical.

A trench sanitary landfill is an area where solid

waste is placed in successive layers in an excavated

trench. The waste is spread, compacted, and covered

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

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

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

in the table are based on the soil properties that affect

the risk of pollution, the ease of excavation,

trafficability, and revegetation. These properties

include permeability, depth to bedrock or a cemented

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

texture, stones and boulders, highly organic layers,

soil reaction, and content of salts and sodium. Unless

otherwise stated, the ratings apply only to that part of

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

trenches, onsite investigation may be needed.

Hard, nonrippable bedrock, creviced bedrock, or

highly permeable strata in or directly below the

proposed trench bottom can affect the ease of

excavation and the hazard of ground-water pollution.

Slope affects construction of the trenches and the

movement of surface water around the landfill. It also

affects the construction and performance of roads in

areas of the landfill.

Soil texture and consistence affect the ease with

which the trench is dug and the ease with which the

soil can be used as daily or final cover. They

determine the workability of the soil when dry and

when wet. Soils that are plastic and sticky when wet

are difficult to excavate, grade, or compact and are

difficult to place as a uniformly thick cover over a layer

of refuse.

The soil material used as the final cover for a trench

landfill should be suitable for plants. It should not have

excess sodium or salts and should not be too acid.

The surface layer generally has the best workability,

the highest content of organic matter, and the best

potential for plants. Material from the surface layer

should be stockpiled for use as the final cover.

In an area sanitary landfill, solid waste is placed in

successive layers on the surface of the soil. The waste

is spread, compacted, and covered daily with a thin

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

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

the completed landfill. The ratings in the table are

based on the soil properties that affect trafficability and

the risk of pollution. These properties include flooding,

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

and depth to bedrock or a cemented pan.

Flooding is a serious problem because it can result

in pollution in areas downstream from the landfill. If

permeability is too rapid or if fractured bedrock, a

fractured cemented pan, or the water table is close to

the surface, the leachate can contaminate the water

supply. Slope is a consideration because of the extra
148 Soil Survey of

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.

Construction Materials

Tables 17a and 17b give information about the soils

as a source of gravel, sand, reclamation material,

roadfill, and topsoil. The soils are rated good, fair, or

poor as a source of reclamation material, roadfill, and

topsoil. They are rated as a probable or improbable

source of sand and gravel. The ratings are based on

soil properties and site features that affect the removal

of the soil and its use as construction material. Normal

compaction, minor processing, and other standard

construction practices are assumed. Each soil is

evaluated to a depth of 5 or 6 feet.

Gravel and sand 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 table 17a, only the

probability 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 engineering classification of the soil),

the thickness of suitable material, and the content of

rock fragments. Gravel is defined as particles ranging

in size from about 0.2 inch to 3 inches in diameter.

Kinds of rock, acidity, and stratification are given in the

soil series descriptions. Gradation of grain sizes is

given in the table on engineering index properties.

A soil rated as a probable source has a layer of

clean sand or gravel or a layer of sand or gravel that is

up to 12 percent silty fines. This material must be at

least 3 feet thick and less than 50 percent, by weight,

large stones. All other soils are rated as an improbable

source. Coarse fragments of soft bedrock, such as

shale and siltstone, are not considered to be sand and

gravel.

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 soil material below the

surface layer to a depth of 5 or 6 feet. It is assumed

that soil layers will be mixed during excavating and

spreading. Many soils have layers of contrasting

suitability within their profile. The table showing

engineering index properties provides detailed

information about each soil layer. This information can

help to determine the suitability of each layer for use

as roadfill. The performance of soil after it is stabilized

with lime or cement is not considered in the ratings.

The ratings are based on soil properties, site

features, and observed performance of the soils. The

thickness of suitable material is a major consideration.

The ease of excavation is affected by large stones, a

high 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
Randolph County, Illinois 149

engineering classification of the soil) and shrink-swell

potential.

Soils rated good contain significant amounts of

sand or gravel or both. They have at least 5 feet of

suitable material, a low shrink-swell potential, few

cobbles and stones, and slopes of 15 percent or less.

Depth to the water table is more than 3 feet. Soils

rated fair are more than 35 percent silt- and clay-sized

particles and have a plasticity index of less than 10.

They have a moderate shrink-swell potential, slopes of

15 to 25 percent, or many stones. Depth to the water

table is 1 to 3 feet. Soils rated poor have a plasticity

index of more than 10, a high shrink-swell potential,

many stones, or slopes of more than 25 percent. They

are wet and have a water table at a depth of less than

1 foot. They may have layers of suitable material, but

the material is less than 3 feet thick.

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.

Plant growth is affected by toxic material and by

such properties as soil reaction, available water

capacity, and fertility. The ease of excavating, loading,

and spreading is affected by rock fragments, slope, a

water table, soil texture, and thickness of suitable

material. Reclamation of the borrow area is affected by

slope, a water table, rock fragments, bedrock, and

toxic material.

Soils rated good have friable, loamy material to a

depth of at least 40 inches. They are free of stones

and cobbles, have little or no gravel, and have slopes

of less than 8 percent. They are low in content of

soluble salts, are naturally fertile or respond well to

fertilizer, and are not so wet that excavation is difficult.

Soils rated fair are sandy soils, loamy soils that

have a relatively high content of clay, soils that have

only 20 to 40 inches of suitable material, soils that

have an appreciable amount of gravel, stones, or

soluble salts, or soils that have slopes of 8 to 15

percent. The soils are not so wet that excavation is

difficult.

Soils rated poor are very sandy or clayey, have less

than 20 inches of suitable material, have a large

amount of gravel, stones, or soluble salts, have slopes

of more than 15 percent, or have a seasonal high

water table at or near the surface.

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.

Water Management

Tables 18a and 18b give information on the soil

properties and site features that affect water

management. The degree and kind of soil limitations

are given for pond reservoir areas; embankments,

dikes, and levees; aquifer-fed excavated ponds;

constructing grassed waterways and surface drains;

constructing terraces and diversions; and tile drains

and underground outlets. 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
150

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.

Grassed waterways and surface drains are natural

or constructed channels, generally broad and shallow,

that conduct surface water to outlets at a nonerosive

velocity. Large stones, wetness, slope, and depth to

bedrock affect the construction of grassed waterways

and surface drains. A hazard of wind erosion, a low

available water capacity, restricted rooting depth, toxic

substances such as salts and sodium, and restricted

permeability adversely affect the growth and

maintenance of the grass after construction.

Terraces and diversions are embankments or a

combination of channels and ridges constructed

across a slope to control erosion and conserve

moisture by intercepting runoff. Slope, wetness, large

stones, and depth to bedrock affect the construction of

terraces and diversions. A restricted rooting depth, a

severe hazard of wind erosion or water erosion, an

excessively coarse texture, and restricted permeability

adversely affect maintenance.

Tile drains and underground outlets are used in

some areas to remove excess subsurface and surface

water from the soil. The ratings in the table apply to the

soil in its undisturbed condition and do not include

consideration of current land use. Depth to bedrock, a

dense layer, or a cemented pan, the content of large

stones, and the content of clay influence the ease of

digging, filling, and compacting. A seasonal high water

table, ponding, and flooding may restrict the period

when excavations can be made. The slope influences

the use of machinery. Soil texture and depth to the

water table influence the resistance to sloughing.

Subsidence of organic layers influences grade and

stability of tile drains.
151

Data relating to soil properties are collected during

the course of the soil survey.

Soil properties are ascertained 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 particle-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 are shown in

tables. They include engineering index properties,

physical and chemical properties, and pertinent soil

and water features.

Engineering Index Properties

Table 19 gives the engineering classifications and

the range of index properties for the layers of each soil

in the survey area.

Depth to the upper and lower boundaries of each

layer is indicated.

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 (fig. 7). “Loam,” for example, is

soil that is 7 to 27 percent clay, 28 to 50 percent silt,

and less than 52 percent sand. If the content of

particles coarser than sand is 15 percent or more, an

appropriate modifier is added, for example, “gravelly.”

Textural terms are defined in the Glossary.

Classification of the soils is determined according to

the Unified soil classification system (ASTM, 2001)

and the system adopted by the American Association

of State Highway and Transportation Officials

(AASHTO, 2000).

The Unified system classifies soils according to

properties that affect their use as construction

material. Soils are classified according to particle-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, CL-ML.

The AASHTO system classifies soils according to

those properties that affect roadway construction and

maintenance. In this system, the fraction of a mineral

soil that is less than 3 inches in diameter is classified

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

basis of particle-size distribution, liquid limit, and

Soil Properties

Figure 7.—Percentages of clay, silt, and sand in the basic

USDA soil textural classes.
152 Soil Survey of

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

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

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

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

visual inspection.

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

A-7 groups are further classified as A-1-a, A-1-b,

A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an

additional refinement, the suitability of a soil as

subgrade material can be indicated by a group index

number. Group index numbers range from 0 for the

best subgrade material to 20 or higher for the poorest.

Rock fragments larger than 10 inches in diameter

and 3 to 10 inches in diameter are indicated as a

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

percentages are estimates determined mainly by

converting volume percentage in the field to weight

percentage.

Percentage (of soil particles) passing designated

sieves is the percentage of the soil fraction less than 3

inches in diameter based on an ovendry weight. The

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

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

millimeters, respectively. Estimates are based on

laboratory tests of soils sampled in the survey area

and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits)

indicate the plasticity characteristics of a soil. The

estimates are based on test data from the survey area

or from nearby areas and on field examination.

The estimates of particle-size distribution, liquid

limit, and plasticity index are generally rounded to the

nearest 5 percent. Thus, if the ranges of gradation and

Atterberg limits extend a marginal amount (1 or 2

percentage points) across classification boundaries,

the classification in the marginal zone is generally

omitted in the table.

Physical Properties

Table 20 shows estimates of some physical

characteristics and features that affect soil behavior.

These estimates are given for the layers of each soil in

the survey area. The estimates are based on field

observations and on test data for these and similar

soils.

Depth to the upper and lower boundaries of each

layer is indicated.

Particle size is the effective diameter of a soil

particle as measured by sedimentation, sieving, or

micrometric methods. Particle sizes are expressed as

classes with specific effective diameter class limits.

The broad classes are sand, silt, and clay, ranging

from the larger to the smaller.

Sand as a soil separate consists of mineral soil

particles that are 0.05 millimeter to 2 millimeters in

diameter. In table 20, 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.

In table 20, the estimated silt content of each soil layer

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

material that is less than 2 millimeters in diameter.

Clay as a soil separate consists of mineral soil

particles that are less than 0.002 millimeter in

diameter. In table 20, the estimated clay content of

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

the soil material that is less than 2 millimeters in

diameter.

The content of sand, silt, and clay affects the

physical behavior of a soil. Particle size is important for

engineering and agronomic interpretations, for

determination of soil hydrologic qualities, and for soil

classification.

The amount and kind of clay affect the fertility and

physical condition of the soil and 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- or 1/10-bar (33kPa or 10kPa) moisture tension.

Weight is determined after the soil is dried at 105

degrees C. In the table, the estimated moist bulk

density of each soil horizon is expressed in grams per

cubic centimeter of soil material that is less than 2

millimeters in diameter. Bulk density data are used to

compute shrink-swell potential, available water

capacity, total pore space, and other soil properties.

The moist bulk density of a soil indicates the pore

space available for water and roots. Depending on soil

texture, a bulk density of more than 1.4 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
Randolph County, Illinois 153

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 soil layer. The

capacity varies, depending on soil properties that

affect retention of water. The most important

properties are the content of organic matter, soil

texture, bulk density, and soil structure. Available water

capacity is an important factor in the choice of plants

or crops to be grown and in the design and

management of irrigation systems. Available water

capacity is not an estimate of the quantity of water

actually available to plants at any given time.

Linear extensibility refers to the change in length of

an unconfined clod as moisture content is decreased

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

volume change between the water content of the clod

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

oven dryness. The volume change is reported in the

table as percent change for the whole soil. Volume

change is influenced by the amount and type of clay

minerals in the soil.

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

if the soil has a linear extensibility of less than 3

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

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

linear extensibility is more than 3, shrinking and

swelling can cause damage to buildings, roads, and

other structures and to plant roots. Special design

commonly is needed.

Organic matter is the plant and animal residue in

the soil at various stages of decomposition. In table

20, 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 by returning crop residue to the soil.

Organic matter has a positive effect on available water

capacity, water infiltration, soil organism activity, and

tilth. It is a source of nitrogen and other nutrients for

crops and soil organisms.

Erosion factors are shown in table 20 as the K

factor (Kw and Kf) and the T factor. Erosion factor K

indicates the susceptibility of a soil to sheet and rill

erosion by water. Factor K is one of six factors used in

the Universal Soil Loss Equation (USLE) and the

Revised Universal Soil Loss Equation (RUSLE) to

predict the average annual rate of soil loss by sheet

and rill erosion in tons per acre per year. The

estimates are based primarily on percentage of silt,

sand, and organic matter and on soil structure and

permeability. Values of K range from 0.02 to 0.69.

Other factors being equal, the higher the value, the

more susceptible the soil is to sheet and rill erosion by

water.

Erosion factor Kw indicates the erodibility of the

whole soil. The estimates are modified by the

presence of rock fragments.

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

size.

Erosion factor T is an estimate of the maximum

average annual rate of soil erosion by wind or water

that can occur without affecting crop productivity over

a sustained period. The rate is in tons per acre per

year.

Wind erodibility groups are made up of soils that

have similar properties affecting their susceptibility to

wind erosion in cultivated areas. The soils assigned to

group 1 are the most susceptible to wind erosion, and

those assigned to group 8 are the least susceptible.

The groups are as follows:

1. Coarse sands, sands, fine sands, and very fine

sands.

2. Loamy coarse sands, loamy sands, loamy fine

sands, loamy very fine sands, ash material, and sapric

soil material.

3. Coarse sandy loams, sandy loams, fine sandy

loams, and very fine sandy loams.

4L. Calcareous loams, silt loams, clay loams, and

silty clay loams.

4. Clays, silty clays, noncalcareous clay loams,

and silty clay loams that are more than 35 percent

clay.

5. Noncalcareous loams and silt loams that are

less than 20 percent clay and sandy clay loams, sandy

clays, and hemic soil material.

6. Noncalcareous loams and silt loams that are

more than 20 percent clay and noncalcareous clay

loams that are less than 35 percent clay.

7. Silts, noncalcareous silty clay loams that are

less than 35 percent clay, and fibric soil material.

8. Soils that are not subject to wind erosion

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 wind erosion, or the tons

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

wind erosion. There is a close correlation between

wind erosion and the texture of the surface layer, the
154 Soil Survey of

size and durability of surface clods, rock fragments,

organic matter, and a calcareous reaction. Soil

moisture and frozen soil layers also influence wind

erosion.

Chemical Properties

Table 21 shows estimates of some chemical

characteristics and features that affect soil behavior.

These estimates are given for the layers of each soil in

the survey area. The estimates are based on field

observations and on test data for these and similar

soils.

Depth to the upper and lower boundaries of each

layer is indicated.

Soil reaction is a measure of acidity or alkalinity.

The pH of each soil horizon is based on many field

tests. For many soils, values have been verified by

laboratory analyses. Soil reaction is important in

selecting crops and other plants, in evaluating soil

amendments for fertility and stabilization, and in

determining the risk of corrosion.

Cation-exchange capacity is the total amount of

extractable bases that can be held by the soil,

expressed in terms of milliequivalents per 100 grams

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

value. Soils having a low cation-exchange capacity

hold fewer cations and may require more frequent

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

reduces the hazard of ground-water pollution.

Calcium carbonate equivalent is the percent of

carbonates, by weight, in the fraction of the soil less

than 2 millimeters in size. The availability of plant

nutrients is influenced by the amount of carbonates in

the soil. Incorporating nitrogen fertilizer into calcareous

soils helps to prevent nitrite accumulation and

ammonium-N volatilization.

Sodium adsorption ratio (SAR) is a measure of the

amount of sodium (Na) relative to calcium (Ca) and

magnesium (Mg) in the water extract from saturated

soil paste. It is the ratio of the Na concentration divided

by the square root of one-half of the Ca + Mg

concentration. Soils that have SAR values of 13 or

more may be characterized by an increased

dispersion of organic matter and clay particles,

reduced permeability and aeration, and a general

degradation of soil structure.

Water Features

Table 22 gives estimates of various water features.

The estimates are used in land use planning that

involves engineering considerations.

Hydrologic soil groups are based on estimates of

runoff potential. Soils are assigned to one of four

groups according to the rate of water infiltration when

the soils are not protected by vegetation, are

thoroughly wet, and receive precipitation from longduration storms.

The four hydrologic soil groups are:

Group A. Soils having a high infiltration rate (low

runoff potential) when thoroughly wet. These consist

mainly of deep, well drained to excessively drained

sands or gravelly sands. These soils have a high rate

of water transmission.

Group B. Soils having a moderate infiltration rate

when thoroughly wet. These consist chiefly of

moderately deep or deep, moderately well drained or

well drained soils that have moderately fine texture to

moderately coarse texture. These soils have a

moderate rate of water transmission.

Group C. Soils having a slow infiltration rate

when thoroughly wet. These consist chiefly of soils

having a layer that impedes the downward movement

of water or soils of moderately fine texture or fine

texture. These soils have a slow rate of water

transmission.

Group D. Soils having a very slow infiltration rate

(high runoff potential) when thoroughly wet. These

consist chiefly of clays that have a high shrink-swell

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

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

and soils that are shallow over nearly impervious

material. These soils have a very slow rate of water

transmission.

If a soil is assigned to a dual hydrologic group (A/D,

B/D, or C/D), the first letter is for drained areas and the

second is for undrained areas.

The months in the table indicate the portion of the

year in which the feature is most likely to be a

concern.

Water table refers to a saturated zone in the soil.

Table 22 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.

Also shown in table 22 is the kind of water table—

that is, apparent or perched. An apparent water table

is a thick zone of free water in the soil. It is indicated

by the level at which water stands in an uncased

borehole after adequate time is allowed for adjustment

in the surrounding soil. A perched water table is water

standing above an unsaturated zone. In places an
Randolph County, Illinois 155

upper, or perched, water table is separated from a

lower one by a dry zone.

Ponding is standing water in a closed depression.

Unless a drainage system is installed, the water is

removed only by percolation, transpiration, or

evaporation. Table 22 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 is the temporary inundation of an area

caused by overflowing streams, by runoff from

adjacent slopes, or by tides. Water standing for short

periods after rainfall or snowmelt is not considered

flooding, and water standing in swamps and marshes

is considered ponding rather than flooding.

Duration and frequency are estimated. Duration is

expressed as extremely brief if 0.1 hour to 4 hours,

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

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

Frequency is expressed as none, very rare, rare,

occasional, frequent, and very frequent. None means

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

unlikely but possible under extremely unusual weather

conditions (the chance of flooding is less than 1

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

under unusual weather conditions (the chance of

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

it occurs infrequently under normal weather conditions

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

frequent that it is likely to occur often under normal

weather conditions (the chance of flooding is more

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

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

likely to occur very often under normal weather

conditions (the chance of flooding is more than 50

percent in all months of any year).

The information is based on evidence in the soil

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

deposited by floodwater; irregular decrease in organic

matter content with increasing depth; and little or no

horizon development.

Also considered are local information about the

extent and levels of flooding and the relation of each

soil on the landscape to historic floods. Information on

the extent of flooding based on soil data is less

specific than that provided by detailed engineering

surveys that delineate flood-prone areas at specific

flood frequency levels.

Soil Features

Table 23 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 restrict roots or

otherwise provide an unfavorable root environment.

Examples are bedrock, cemented layers, dense

layers, and frozen layers. Depth to top is the vertical

distance from the soil surface to the upper boundary of

the restrictive layer.

Potential for frost action is the likelihood of upward

or lateral expansion of the soil caused by the formation

of segregated ice lenses (frost heave) and the

subsequent collapse of the soil and loss of strength on

thawing. Frost action occurs when moisture moves

into the freezing zone of the soil. Temperature, texture,

density, permeability, content of organic matter, and

depth to the water table are the most important factors

considered in evaluating the potential for frost action. It

is assumed that the soil is not insulated by vegetation

or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in

winter are the most susceptible to frost action. Well

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

susceptible. Frost heave and low soil strength during

thawing cause damage to pavements and other rigid

structures.

Risk of corrosion pertains to potential soil-induced

electrochemical or chemical action that corrodes or

weakens uncoated steel or concrete. The rate of

corrosion of uncoated steel is related to such factors

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

electrical conductivity of the soil. The rate of corrosion

of concrete is based mainly on the sulfate and sodium

content, texture, moisture content, and acidity of the

soil. Special site examination and design may be

needed if the combination of factors results in a severe

hazard of corrosion. The steel or concrete in

installations that intersect soil boundaries or soil layers

is more susceptible to corrosion than the steel or

concrete in installations that are entirely within one

kind of soil or within one soil layer.

For uncoated steel, the risk of corrosion, expressed
156

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.

place, concretions of iron oxide or manganese

oxide are generally considered a type of

redoximorphic concentration.

combination with needed cultural and

management practices. In a good conservation

cropping system, the soil-improving crops and

practices more than offset the effects of the soildepleting crops and practices. Cropping systems

are needed on all tilled soils. Soil-improving

practices in a conservation cropping system

include the use of rotations that contain grasses

and legumes and the return of crop residue to the

soil. Other practices include the use of green

control.

Conservation tillage. A tillage system that does not

invert the soil and that leaves a protective amount

of crop residue on the surface throughout the year.

planned system of rotation and management

practices.

Culmination of the mean annual increment (CMAI).

The average annual increase per acre in the

volume of a stand. Computed by dividing the total

areas by diverting runoff from its natural course.

Drainage class (natural). Refers to the frequency and

duration of wet periods under conditions similar to

those under which the soil formed. Alterations of

the water regime by human activities, either

through drainage or irrigation, are not a

consideration unless they have significantly

changed the morphology of the soil. Seven

classes of natural soil drainage are recognized—

excessively drained, somewhat excessively

drained, well drained, moderately well drained,

somewhat poorly drained, poorly drained, and

very poorly drained. These classes are defined in

the “Soil Survey Manual.”

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

from an area.

Drainageway. An area of ground at a lower elevation

than the surrounding ground and in which water

collects and is drained to a closed depression or

lake or to a drainageway at a lower elevation. A

drainageway may or may not have distinctly

incised channels at its upper reaches or

throughout its course.

the lowest bulk density and the highest water

content at saturation of all organic soil material.

Field moisture capacity. The moisture content of a

soil, expressed as a percentage of the ovendry

weight, after the gravitational, or free, water has

drained away; the field moisture content 2 or 3

glaciers and subsequently sorted and deposited

by streams flowing from the melting ice. The

deposits are stratified and occur as kames,

eskers, deltas, and outwash plains.

Glaciolacustrine deposits (geology). Material

ranging from fine clay to sand derived from

glaciers and deposited in glacial lakes mainly by

glacial meltwater. Many deposits are interbedded

or laminated.

much as 3 inches (2 millimeters to 7.6

centimeters) in diameter. An individual piece is a

pebble.

Gravelly soil material. Material that has 15 to 35

percent, by volume, rounded or angular rock

fragments, not prominently flattened, as much as

of maturity or soon after maturity.

Ground water (geology). Water filling all the

unblocked pores of the material below the water

table.

Gully. A miniature valley with steep sides cut by

running water and through which water ordinarily

runs only after rainfall. The distinction between a

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

an obstacle to farm machinery and is too deep to

be obliterated by ordinary tillage; a rill is of lesser

depth and can be smoothed over by ordinary

tillage.

Hard bedrock. Bedrock that cannot be excavated

except by blasting or by the use of special

equipment that is not commonly used in

construction.

Hard to reclaim (in tables). Reclamation is difficult

after the removal of soil for construction and other

material intermediate in degree of decomposition

between the less decomposed fibric material and

the more decomposed sapric material.

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

the surface, having distinct characteristics

produced by soil-forming processes. In the

identification of soil horizons, an uppercase letter

represents the major horizons. Numbers or

lowercase letters that follow represent

subdivisions of the major horizons. An explanation

of the subdivisions is given in the “Soil Survey

Manual.” The major horizons of mineral soil are as

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.

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
Randolph County, Illinois 163

unlike that in which the solum formed. If the

material is known to differ from that in the solum,

an Arabic numeral, commonly a 2, precedes the

letter C.

Cr horizon.—Soft, consolidated bedrock beneath

the soil.

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

Humus. The well decomposed, more or less stable

part of the organic matter in mineral soils.

Hydrologic soil groups. Refers to soils grouped

according to their runoff potential. The soil

properties that influence this potential are those

that affect the minimum rate of water infiltration on

a bare soil during periods after prolonged wetting

when the soil is not frozen. These properties are

depth to a seasonal high water table, the infiltration

rate and permeability after prolonged wetting, and

depth to a very slowly permeable layer. The slope

and the kind of plant cover are not considered but

are separate factors in predicting runoff.

horizon to another in the soil profile. Generally,

material is removed from an upper horizon and

deposited in a lower horizon.

Infiltration. The downward entry of water into the

immediate surface of soil or other material, as

contrasted with percolation, which is movement of

water through soil layers or material.

Infiltration capacity. The maximum rate at which

water can infiltrate into a soil under a given set of

conditions.

Infiltration rate. The rate at which water penetrates

the surface of the soil at any given instant, usually

expressed in inches per hour. The rate can be

limited by the infiltration capacity of the soil or the

rate at which water is applied at the surface.

Intake rate. The average rate of water entering the

soil under irrigation. Most soils have a fast initial

rate; the rate decreases with application time.

Therefore, intake rate for design purposes is not a

constant but is a variable depending on the net

irrigation application. The rate of water intake, in

inches per hour, is expressed as follows:

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

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

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

change between the water content of the clod at

1

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

and oven dryness. Volume change is influenced by

the amount and type of clay minerals in the soil.

The volume change is the percent change for the

whole soil. If it is expressed as a fraction, the

resulting value is COLE, coefficient of linear

extensibility.

Survey Manual.” In line with conventional usage in

the engineering profession and with traditional

slopes.

Taxadjuncts. Soils that cannot be classified in a

series recognized in the classification system.

Such soils are named for a series they strongly

the series for which the soils are named.

Terminal moraine. A belt of thick glacial drift that

generally marks the termination of important

glacial advances.

favorable material for plant growth. It is ordinarily

rich in organic matter and is used to topdress

roadbanks, lawns, and land affected by mining.

Understory. Any plants in a forest community that

grow to a height of less than 5 feet.

Upland (geology). Land at a higher elevation, in

general, than the alluvial plain or stream terrace;

land above the lowlands along 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.

glaciolacustrine layers seasonally deposited,

usually by meltwater streams, in a glacial lake or

other body of still water in front of a glacier.

Weathering. All physical and chemical changes

Table 17a.--Construction Materials

(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)

Printing Soil Survey Maps 

The soil survey maps were made at a scale of 1:12000 and were designed to be

used at that scale. To print the maps at 1:12000 scale, set the view to Actual

Size from the View pull down menu.

Using the pan tool, go to the area you would like to print. Select the Graphic

Selection Tool by holding down the Text Selection Tool button and clicking on the

Graphic Selection Tool button.
Then using the Graphic Selection Tool drag a box around the area you would like

to print. Note dashed lines forming a box around area to print.

Select File Print. The Print Range will be set to Selected graphic. Click OK and

the map will be sent to the printer.

subsurface layer of the named soils in the surrounding map unit are

darker. Typically 0.25 acre to 2.0 acres.

GSP

Gully A small channel with steep sides cut by running water through which

water ordinarily runs only after a rain or after melting of snow or ice.

It generally is an obstacle to wheeled vehicles and is too deep to be

obliterated by ordinary tillage.

GUL

Iron bog An accumulation of iron in the form of nodules, concretions, or soft

masses on the surface or near the surface of soils. Typically 0.2 acre

to 2.0 acres.

BFE

Landfill An area of accumulated waste products of human habitation, either

above or below natural ground level. Typically 0.2 acre to 2.0 acres.

LDF

Levee An embankment that confines or controls water, especially one built

along the banks of a river to prevent overflow onto lowlands.

LVS

Marsh or swamp A water-saturated, very poorly drained area that is intermittently or

permanently covered by water. Sedges, cattails, and rushes are the

dominant vegetation in marshes, and trees or shrubs are the dominant

vegetation in swamps. Typically 0.2 acre to 2.0 acres.

MAR

Mine or quarry An open excavation from which soil and underlying material have

been removed and in which bedrock is exposed. Also denotes surface

openings to underground mines. Typically 0.2 acre to 2.0 acres.

MPI

Mine subsided area An area that is lower than the soils in the surrounding map unit

because of subsurface coal mining. Typically 0.25 acre to 3.0 acres.

MSA

Miscellaneous water A small, constructed body of water that is used for industrial,

sanitary, or mining applications and that contains water most of the

year. Typically 0.2 acre to 2.0 acres.

MIS

Muck spot An area that occurs within an area of poorly drained or very poorly

drained soil and that has a histic epipedon or an organic surface

layer. The symbol is used only in map units consisting of mineral

soil. Typically 0.2 acre to 2.0 acres.

MUC

Oil brine spot An area of soil that has been severely damaged by the accumulation

of oil brine, with or without liquid oily wastes. The area is typically

barren but may have a vegetative cover of salt-tolerant plants.

Typically 0.2 acre to 2.0 acres.

OBS

Perennial water A small, natural or constructed lake, pond, or pit that contains water

most of the year. Typically 0.2 acre to 2.0 acres.

WAT
Name Description Label

Rock outcrop An exposure of bedrock at the surface of the earth. Not used where

the named soils of the surrounding map unit are shallow over

bedrock or where “Rock outcrop” is a named component of the map

unit. Typically 0.2 acre to 2.0 acres.

ROC

Saline spot An area where the surface layer has an electrical conductivity of 8

mmhos/cm-l more than the surface layer of the named soils in the

surrounding map unit. The surface layer of the surrounding soils has

an electrical conductivity of 2 mmhos/cm-l or less. Typically 0.2

acre to 2.0 acres.
