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 1998. Soil names and

descriptions were approved in 1998. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 1998. 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

Henry County Soil and Water Conservation District. Financial assistance was provided

by the 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.

HENRY COUNTY is in northwestern Illinois (fig. 1). It

has an area of 528,120 acres, or 826 square miles. It

is bounded by Whiteside County on the north, Bureau

and Stark Counties on the east, Mercer and Rock

Island Counties on the west, Knox and Stark Counties

on the south, and the Rock River in the northwest

corner.

Henry County was established in 1837. In 2000, the

population of the county was 51,020 (U.S. Department

of Commerce, 2002). Cambridge, the county seat, had

a population of 2,180. Kewanee, the largest town, had

a population of 12,944.

This soil survey updates the survey of Henry

County published in 1984 (Elmer, 1984). It provides

additional information and has larger maps, which

show the soils in greater detail.

General Nature of the County

This section provides some general information

about Henry County. It describes transportation

facilities and industry; farming; relief, physiography,

and drainage; and climate.

Transportation Facilities and Industry

Henry County has a well developed system of

transportation. Interstate Highway 74 and U.S.

Highway 150 cross the county from north to south.

Interstate Highway 80 and U.S. Highways 6 and 34

cross the county from east to west. Several state

roads also cross the county. The main secondary

roads are blacktopped. Most rural areas are

accessible by all-weather roads. Railroads furnish

freight service to the county.

Several industries are established in the county.

These include manufacturers of farm and other

equipment and concrete and building material. The

factories are at Kewanee, Galva, and Geneseo. A

large limestone quarry is at Cleveland. A number of

pits provide crushed rock for roads and sand and

gravel for building material. Hybrid seed corn is grown

in the county. A commercial seed corn company is at

Geneseo. Strip mining for coal in the past has

significantly altered the use and productivity of about

3,000 acres in the east-central part of the county.

Farming

Farming has been a major enterprise in Henry

County since its settlement. In 2000, there were 1,344

operating farms in the county (Illinois Agricultural

Statistics Service, 2001). The average farm size is

about 340 acres. Some livestock is raised on about 80

percent of the farms. Much of the grain produced on

the farms is fed to the livestock.

Corn, soybeans, and hay are the main crops. In

2000, the acreage used for corn was 210,000, the

acreage used for soybeans was 165,000, and the

acreage used for hay was 12,700 (Illinois Agricultural

Statistics Service, 2001).

Hogs and cattle are the main livestock. In 2000, the

total number of swine was 195,400 and the total

number of cattle was 50,900 (Illinois Agricultural

Statistics Service, 2001).

Relief, Physiography, and Drainage

Dr. Richard C. Anderson, retired professor, Department of

Geology, Augustana College, helped prepare this section.

The topography of Henry County consists of upland

plains; dissected valley sides; a broad, sandy plain

that has dunes; and flood plains (fig. 2). This

landscape is the result of the action of continental

glaciers in the recent geologic past and of postglacial

stream erosion (Leighton and Brophy, 1961). The

gently rolling uplands are the result of glacial

deposition, and the dissected valley sides and flood

plains are the result of postglacial stream erosion. The

broad, sandy plain that has dunes is a glacial outwash

plain deposited by meltwater.

The upland plains are remnants of a formerly

continuous surface of glacial deposits (Leighton and

Brophy, 1961). In Henry County, they are at elevations

ranging from less than 650 feet above sea level in the

northwest to 875 feet in the southeast. Although

largely of glacial origin, they are covered by 10 feet or

more of wind-deposited loess, which reaches a

maximum thickness—more than 50 feet—on the bluffs

south and east of Geneseo. The upland plains function

as stream divides separating adjacent stream

drainage basins. They are surrounded by innumerable

tributary valleys that drain into the larger streams in

the county. The dissected valley sides are in the

steepest and most rugged parts of the county. The

relief along the dissected valley sides is as much as

150 feet along the bluffs of the Rock River

downstream from Green Rock. Elsewhere, the relief

from the uplands to the adjacent valley floor rarely

exceeds 100 feet.

The northeastern part of the county is a broad,

sandy plain where stabilized sand dunes are very

common. The sand was deposited by glacial meltwater

when the front of the glacier was east of Henry County

in a position now marked by the Bloomington Moraine

in Bureau County. In Henry County, the elevation of

the plain ranges from 625 feet above sea level in the

east to 600 feet in the west. The sand dunes are most

prominent in northeast- to southwest-trending zones

lying north of the Green River. In these zones, the

dunes lie directly southeast of the broad, shallow

valleys that cross the area from northeast to

southwest and drain toward the Green River. Aside

from the dunes, many of which rise 50 to 100 feet

above the level of the plain, the relief of the plain is

very low, generally less than 25 feet.

Flood plains occur along most of the streams in the

county. The broadest are those along the largest

streams—the Rock River, the Green River, and the

Edwards River. Flood plains are the floors of the

valleys, which have been cut by the streams. They are

subject to periodic flooding. They are underlain by

river-deposited silt, clay, and sand that, in turn, overlie

consolidated limestone or shale bedrock. Along the

Rock River, bedrock is at a depth of less than 10 feet

in many places. In some areas along the other

streams in the county, the bedrock is at a depth of

100 feet or more. Terraces underlain by fine sand or

small amounts of gravel are common on the flood

plains.

Climate

Henry County is cold in winter. The summers are

generally hot but have occasional cool spells.

Precipitation falls as snow during frequent snowstorms

in winter and chiefly as rain showers, which often are

heavy, during the warmer periods, when warm moist

air moves in from the south. The amount of annual

rainfall usually is adequate for corn, soybeans, and

small grain.

Table 1 provides data on temperature and

precipitation for the survey area as recorded at

Geneseo during the period 1971 to 2000. 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 24 degrees F

and the average monthly minimum temperature is 17

degrees. The lowest temperature on record, which

occurred at Geneseo on February 3, 1996, is -24

degrees. In summer, the average temperature is 73

degrees and the average daily maximum temperature

is 84 degrees. The highest recorded temperature,

which occurred at Geneseo on August 17, 1988, is

103 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 (50 degrees F). The normal monthly

accumulation is used to schedule single or successive

plantings of a crop between the last freeze in spring

and the first freeze in fall.

Total annual precipitation is 37.41 inches. Of this

total, 23.66 inches, or about 63 percent, usually falls in

April through September. The growing season for most

crops falls within this period. In 2 years out of 10, the

rainfall in April through September is less than 11.30

inches. The heaviest 1-day rainfall on record is 5.20

inches. Thunderstorms occur on about 50 days each

year.

Figure 2.—A physiographic map of Henry County. The average seasonal snowfall is 27.8 inches. The
20 Soil Survey of

greatest snow depth at any one time during the period

of record is 29 inches. On the average, 45 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.

Tornadoes and severe thunderstorms strike

occasionally. They are of local extent and of short

duration and cause only sparse damage in narrow

belts. Hailstorms sometimes occur during the warmer

periods. The hail falls in scattered small areas.

How This Survey Was Made

This survey was made to provide updated

information about the soils and miscellaneous areas in

Henry County, which is a subset of Major Land

Resource Area 108B (fig. 1). Major land resource

areas (MLRAs) are geographically associated land

resource units that share a common land use,

elevation, topography, climate, water, soils, and

vegetation (USDA, 1981). Map unit design and the soil

descriptions are based on the occurrence of each soil

throughout the MLRA. In some cases a soil may be

referred to that does not occur in the Henry County

subset but that is representative of the MLRA.

The information includes a description of the soils

and miscellaneous areas and their location and a

discussion of their properties and the subsequent

effects on suitability, limitations, and management for

specified uses. Soil scientists observed the steepness,

length, and shape of the slopes; the general pattern of

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

kinds of bedrock. They dug many holes to study the

soil profile, which is the sequence of natural layers, or

horizons, in a soil. The profile extends from the surface

down into the unconsolidated material in which the soil

formed. The unconsolidated material is devoid of roots

and other living organisms and has not been changed

by other biological activity.

The soils and miscellaneous areas in the survey

area are in an orderly pattern that is related to the

geology, landforms, relief, climate, and natural

vegetation of the area. Each kind of soil and

miscellaneous area is associated with a particular kind

or segment of the landscape. By observing the soils

and miscellaneous areas in the survey area and

relating their position to specific segments of the

landscape, soil scientists develop a concept, or model,

of how the soils were formed. Thus, during mapping,

this model enables the soil scientists to predict with a

considerable degree of accuracy the kind of soil or

miscellaneous area at a specific location on the

landscape.

Individual soils on the landscape commonly merge

into one another as their characteristics gradually

change. To construct an accurate map, however, soil

scientists must determine the boundaries between the

soils. They can observe only a limited number of soil

profiles. Nevertheless, these observations,

supplemented by an understanding of the soilvegetation-landscape relationship, are sufficient to

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

determine the boundaries.

Soil scientists recorded the characteristics of the

soil profiles that they studied. They noted soil color,

texture, size and shape of soil aggregates, kind and

amount of rock fragments, distribution of plant roots,

soil reaction, and other features that enable them to

identify soils. After describing the soils in the survey

area and determining their properties, the soil

scientists assigned the soils to taxonomic classes

(units). Taxonomic classes are concepts. Each

taxonomic class has a set of soil characteristics with

precisely defined limits. The classes are used as a

basis for comparison to classify soils systematically.

Soil taxonomy, the system of taxonomic classification

used in the United States, is based mainly on the kind

and character of soil properties and the arrangement

of horizons within the profile. After the soil scientists

classified and named the soils in the survey area, they

compared the individual soils with similar soils in the

same taxonomic class in other areas so that they

could confirm data and assemble additional data

based on experience and research.

While a soil survey is in progress, samples of some

of the soils in the area generally are collected for

laboratory analyses and for engineering tests. Soil

scientists interpret the data from these analyses and

tests as well as the field-observed characteristics and

the soil properties to determine the expected behavior

of the soils under different uses. Interpretations for all

of the soils are field tested through observation of the

soils in different uses and under different levels of

management. Interpretations are modified as

necessary 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 seasonal high
Henry County, Illinois 21

water table within certain depths in most years, but

they cannot predict that the water table will always be

at a specific level in the soil on a specific date.

After soil scientists located and identified the

significant natural bodies of soil in the survey area,

they drew the boundaries of these bodies on aerial

photographs and identified each as a specific map

unit. Aerial photographs show trees, buildings, fields,

roads, and rivers, all of which help in locating

boundaries accurately.

The descriptions, names, and delineations of the

soils in this survey may not fully agree with those of

the soils in adjacent survey areas. Differences are the

result of a better knowledge of soils, modifications in

series concepts, or variations in the intensity of mapping

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

23

This section relates the soils in the survey area to

the major factors of soil formation and describes the

system of soil classification.

Formation of the Soils

Soil-forming processes act on deposited or

accumulated geologic material. The characteristics of

the soil at any given point are determined by the

parent material, living organisms on and in the soil, the

climate, the topography, and the length of time that the

forces of soil formation have acted on the soil material.

Climate and living organisms are active factors of

soil formation. As they act on the parent material that

has accumulated through the weathering of rocks and

that may have been relocated by water, glaciers, or

wind, they slowly change the material into a natural

body that has genetically related horizons. The effects

of climate and living organisms are conditioned by

topography. The parent material affects the kind of soil

profile that forms. Finally, time is needed for changing

the parent material into a soil. Usually, a long time is

needed for the formation of distinct horizons. The

importance of each factor differs from place to place,

and each modifies the effect of the other four. In some

areas one factor dominates the formation of a soil.

Human activities, such as clearing forests, cultivating,

and applying fertilizer, also affect soil formation.

Parent Material

Parent material is the unconsolidated mass in which

a soil forms. It determines the chemical and

mineralogical composition of the soil. Wind, glaciers, or

meltwater from glaciers deposited some of the parent

material in Henry County (Leighton and Brophy, 1961).

In some areas it was reworked and redeposited by

subsequent actions of water and wind. Although all of

the parent material in the county is of common glacial

origin, its properties vary greatly, sometimes within

small areas, depending on how the material was

deposited. The soils in the county formed dominantly

in loess; glacial till; outwash deposits; lacustrine

deposits; alluvium; organic material; and residuum, or

material weathered from bedrock.

Peoria loess is the major parent material in the

county. The Mississippi River Valley was the main

source of the loess. Wind picked up silt from the valley

floor and redeposited it in the uplands. The loess is

about 30 feet thick in nearly level areas on uplands.

Osco soils are examples of soils that formed in loess.

These soils typically are moderately fine textured and

have a strongly expressed structure.

Glacial till is material laid down directly by glaciers

with a minimum of water action. It consists of particles

of different sizes that are mixed together. The small

pebbles in glacial till have sharp corners, indicating

that they have not been worn by washing water. All of

the till in the county is of Illinoian age. In some areas it

retains a Sangamon paleosol. Atlas and other modern

soils formed in these areas. In many areas the

paleosol has been removed by erosion. Hickory soils

formed in these areas. In a few areas the till contains

carbonates within a depth of 40 inches. Senachwine

soils formed in these areas.

Outwash material is deposited by running water

from melting glaciers. The size of the particles varies,

depending on the speed of the stream that carried the

material. When the water slowed down, the coarser

particles were deposited. The finer particles, such as

very fine sand, silt, and clay, were carried by the more

slowly moving water. Outwash deposits generally

consist of layers of particles that are similar in size,

such as silt loam, sandy loam, and sand. La Hogue

soils formed in loamy deposits of outwash material. In

many areas a thin layer of loess covers the outwash

deposits. Plano and Proctor soils are examples of soils

that formed in this material. In some of these areas,

the outwash is a thin deposit overlying glacial till.

Lacustrine material was deposited from still or

ponded glacial meltwater. After the coarser fragments

were deposited as outwash by moving water, the finer

particles, such as very fine sand, silt, and clay, settled

in the still water. As a result, the soils that formed in

lacustrine deposits are typically fine textured. Niota

soils formed in lacustrine material.

Formation and Classification of the Soils
24 Soil Survey of

The alluvium in the county was recently deposited

by floodwater from streams. It varies in texture,

depending on the speed of the water from which it was

deposited. Examples of alluvial soils are Radford and

Sawmill soils.

Organic material is made up of deposits of plant

remains. After the glaciers withdrew from the area,

water was left standing in depressions on outwash

plains and lake plains. As the grasses and sedges

growing around the edges of these lakes died, their

remains fell to the bottom. Later, water-tolerant trees

grew in these areas. As these trees died, their residue

became part of the organic accumulation. When the

lakes eventually were filled with organic material,

areas of muck and peat formed. Palms and other soils

formed in organic material.

Shale bedrock is predominantly buried by loess,

glacial till, outwash, and alluvium in Henry County.

Along side slopes on dissected uplands, however, the

material weathered from shale bedrock is the parent

material of some soils, such as Marseilles soils.

Living Organisms

Plants are the principal living organisms that affect

the formation of the soils in Henry County. Bacteria,

fungi, and earthworms, however, also have affected

soil formation. The chief contribution of plant and

animal life is the addition of organic matter and

nitrogen to the soil. The kind of organic material on

and in the soil depends on the kind of plants that grew

on the soil. The remains of these plants accumulate in

the surface layer, decay, and eventually become

organic matter. The roots of the plants provide

channels for the downward movement of water

through the soil and add organic matter as they decay.

Bacteria in the soil help to break down the organic

matter and thus help to provide plant nutrients.

The native vegetation in the county was trees and

prairie grasses. The sloping soils formed mainly under

forests of oak, hickory, and similar trees. The nearly

level soils formed under prairie grasses. They have a

darker and thicker surface layer than that of the soils

that formed under forest vegetation. Also, they have a

higher content of organic matter. Fayette soils are an

example of soils that formed under forest vegetation.

Muscatune soils formed under prairie vegetation.

Climate

Climate is an important factor in the formation of

soils. It influences the kind of plant and animal life on

and in the soil. Precipitation affects the weathering of

minerals and the transporting of soil material.

Temperature determines the rate of chemical reaction

that occurs in the soil. The general climate has had an

important overall influence on the characteristics of the

soils, but it does not cause major differences among

soils in a relatively small area, such as a county.

The climate in Henry County is temperate and

humid. It is probably similar to the climate under which

the soils formed.

Topography

Topography, or relief, has a marked influence on the

soils through its effect on natural drainage, erosion,

plant cover, and soil temperature. In Henry County, the

slopes dominantly range from 0 to 60 percent. Natural

soil drainage ranges from excessively drained on

sandy ridgetops to very poorly drained in depressions.

Topography influences the formation of soils by

affecting runoff and drainage. Drainage, in turn,

through its effect on aeration of the soils, determines

the color of the soil. Runoff is most rapid on the

steeper slopes, but in low areas, water is temporarily

ponded. Water and air move freely through well

drained soils but slowly through poorly drained soils. In

well aerated soils, the iron compounds that give most

soils their color are brightly colored. In poorly aerated

soils, the colors are gleyed and mottled. Fayette soils

are examples of well drained, well aerated soils. Sable

soils are examples of poorly drained, poorly aerated

soils.

Time

The length of time needed for the formation of a soil

depends on the other factors of soil formation.

Differences in the length of time that the parent

materials have been in place are commonly reflected

in the degree of profile development. Soils form more

rapidly and are more acid if the parent material is low

in content of calcium (lime). The more rapidly

permeable soils form more readily than slowly

permeable soils because calcium and other soluble

minerals are leached more quickly. Soils form more

quickly under forest vegetation than under prairie

vegetation because grasses are more efficient in

recycling calcium and other bases from the subsoil to

the surface layer. Soils generally form more quickly in

a humid climate than in a dry climate.

The soils in Henry County range from young to

mature. Most of the soils on uplands are moderately
Henry County, Illinois 25

developed. The soils in the northern part of the county

and on terraces are weakly developed.

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

county. 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

great groups on the basis of close similarities in kind,

arrangement, and degree of development of

pedogenic horizons; soil moisture and temperature

regimes; and base status. Each great group is

identified by the name of a suborder and by a prefix

that indicates a property of the soil. An example is

Endoaquolls (Endo, meaning within, 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 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. The adjective

Typic identifies the subgroup that typifies the great

group. An example is Typic 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 class,

mineral content, cation-exchange capacity,

temperature regime, thickness of the root zone,

consistence, moisture equivalent, slope, and

permanent cracks. A family name consists of the

name of a subgroup preceded by terms that indicate

soil properties. An example is fine-silty, mixed,

superactive, mesic Typic Endoaquolls.

SERIES. The series consists of soils that have

similar horizons in their profile. The horizons are

similar in color, texture, structure, reaction,

consistence, mineral and chemical composition, and

arrangement in the profile. The texture of the surface

layer or of the substratum can differ within a series.

The Drummer series is an example of a soil series in

this survey area.

27

In this section, arranged in alphabetical order, each

soil series recognized in the survey area is described.

Each series description is followed by detailed

descriptions of the associated 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 “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 soil maps in this survey

represent the soils or miscellaneous areas in the

survey area. These soils or miscellaneous areas are

listed as individual components in the map unit

description. 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

Soil Series and Detailed Soil Map Units
28 Soil Survey of

divided into soil phases. Most of the areas shown on

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, Hickory silt loam,

10 to 18 percent slopes, eroded, is a phase of the

Hickory series.

A map unit is named for the component or

components that make up a dominant percentage of

the map unit. Many map units consist of one dominant

component. These map units are consociations. Sable

silty clay loam, 0 to 2 percent slopes, is an example.

Some map units are made up of two or more

dominant components. These map units are

complexes. A complex consists of two or more

components in such an intricate pattern or in such

small areas that they cannot be shown separately on

the maps. Attempting to delineate the individual

components of a complex would result in excessive

clutter that could make the map illegible. The pattern

and proportion of the components in a complex are

somewhat similar in all areas. Timula-Hickory silt

loams, 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 “Miscellaneous water” 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.

Use and Management of the Soils
178 Soil Survey of

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 6. 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). 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 6.

Land Capability Classification

Land capability classification shows, in a general

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

Crops that require special management are excluded.

The soils are grouped according to their limitations for

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

crops, and the way they respond to management. The

criteria used in grouping the soils do not 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 6.

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 resources, 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

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 384,912 acres in the survey area, or about

73 percent of the total acreage, meets the soil

requirements for prime farmland.

The map units in the survey area that meet the

criteria for prime farmland are listed in table 7. 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.”

Forestland Management and

Productivity

The tables in this section can help forest owners or

managers plan the use of soils for wood crops. They

show the potential productivity of the soils for wood

crops and rate the soils according to the limitations

that affect various aspects of forestland management.
180 Soil Survey of

Forestland Productivity

In table 8, the potential productivity of merchantable

or common trees on a soil is expressed as a site index

and as a volume number. 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. Commonly grown trees are those

that forest managers generally favor in intermediate or

improvement cuttings. They are selected on the basis

of growth rate, quality, value, and marketability. More

detailed information regarding site index is available in

the “National Forestry Manual,” which is available in

local offices of the Natural Resources Conservation

Service or on the Internet.

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

likely to be produced by the most important tree

species. 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, evenaged, 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.

Forestland Management

In tables 9a through 9e, interpretive ratings are

given for various aspects of forestland management.

The ratings are both verbal and numerical.

Some rating class terms indicate the degree to

which the soils are suited to a specified forestland

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 fire damage and 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 fire damage or 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 forestland

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.

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
Henry County, Illinois 181

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 damage to soil

by fire are based on texture of the surface layer,

content of rock fragments and organic matter in the

surface layer, thickness of the surface layer, and slope.

The soils are described as having a low, moderate, or

high potential for this kind of damage. The ratings

indicate an evaluation of the potential impact of

prescribed fires or wildfires that are intense enough to

remove the duff layer and consume organic matter in

the surface layer.

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

stock of suitable species should be planted properly

on a well prepared site and maintained in good

condition.

Table 10 shows the height that locally grown trees

and shrubs are expected to reach in 20 years on

various soils. The estimates in table 10 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
182 Soil Survey of

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 soils of the survey area are rated in tables 11a

and 11b according to limitations that affect their

suitability for recreation. The ratings are both verbal

and numerical. Rating class terms indicate the extent

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

that affect the recreational uses. Not limited indicates

that the soil has features that are very favorable for the

specified use. Good performance and very low

maintenance can be expected. Somewhat limited

indicates that the soil has features that are moderately

favorable for the specified use. The limitations can be

overcome or minimized by special planning, design, or

installation. Fair performance and moderate

maintenance can be expected. Very limited indicates

that the soil has one or more features that are

unfavorable for the specified use. The limitations

generally cannot be overcome without major soil

reclamation, special design, or expensive installation

procedures. Poor performance and high maintenance

can be expected.

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

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

limitation (0.00).

The ratings in the tables are based on restrictive

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

the surface layer. Susceptibility to flooding is

considered. Not considered in the ratings, but

important in evaluating a site, are the location and

accessibility of the area, the size and shape of the

area and its scenic quality, vegetation, access to

water, potential water impoundment sites, and access

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

septic tank effluent and the ability of the soil to support

vegetation also are important. Soils that are subject to

flooding are limited for recreational uses by the

duration and intensity of flooding and the season when

flooding occurs. In planning recreational facilities,

onsite assessment of the height, duration, intensity,

and frequency of flooding is essential.

The information in tables 11a and 11b can be

supplemented by other information in this survey, for

example, interpretations for building site development,

construction materials, sanitary facilities, and water

management.

Camp areas require site preparation, such as

shaping and leveling the tent and parking areas,

stabilizing roads and intensively used areas, and

installing sanitary facilities and utility lines. Camp

areas are subject to heavy foot traffic and some

vehicular traffic. The ratings are based on the soil

properties that affect the ease of developing camp

areas and the performance of the areas after

development. Slope, stoniness, and depth to bedrock

or a cemented pan are the main concerns affecting

the development of camp areas. The soil properties

that affect the performance of the areas after

development are those that influence trafficability and

promote the growth of vegetation, especially in heavily

used areas. For good trafficability, the surface of camp

areas should absorb rainfall readily, remain firm under

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Picnic areas are subject to heavy foot traffic. Most

vehicular traffic is confined to access roads and

parking areas. The ratings are based on the soil

properties that affect the ease of developing picnic

areas and that influence trafficability and the growth of

vegetation after development. Slope and stoniness are

the main concerns affecting the development of picnic

areas. For good trafficability, the surface of picnic

areas should absorb rainfall readily, remain firm under

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Playgrounds require soils that are nearly level, are

free of stones, and can withstand intensive foot traffic.

The ratings are based on the soil properties that affect

the ease of developing playgrounds and that influence

trafficability and the growth of vegetation after

development. Slope and stoniness are the main

concerns affecting the development of playgrounds.

For good trafficability, the surface of the playgrounds

should absorb rainfall readily, remain firm under heavy

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that
Henry County, Illinois 183

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

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 12, 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

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 corn, soybeans, wheat, 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 bromegrass, timothy, orchardgrass,

clover, alfalfa, wheatgrass, and birdsfoot trefoil.

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 bluestems, indiangrass,

blueberry, goldenrod, dandelions, blackberry, ragweed,

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, cherry,

birch, maple, green ash, willow, and American elm.
184 Soil Survey of

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, fir, cedar, and tamarack.

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, rushes,

sedges, bulrushes, wild rice, arrowhead,

waterplantain, cattail, prairie cordgrass, bluejoint

grass, asters, and beggarticks.

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 marshes, waterfowl feeding

areas, wildlife watering developments, beaver ponds,

and other wildlife 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 Hungarian partridge, ring-necked

pheasant, bobwhite quail, sharp-tailed grouse,

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, ruffed

grouse, thrushes, woodpeckers, owls, tree squirrels,

porcupine, raccoon, deer, and bear.

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.

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.
Henry County, Illinois 185

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 13 lists the hydric characteristics of the soils

in Henry 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).

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 14a and

14b 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
186 Soil Survey of

reclamation, special design, or expensive installation

procedures. Poor performance and high maintenance

can be expected.

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

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

limitation (0.00).

Dwellings are single-family houses of three stories

or less. For dwellings without basements, the

foundation is assumed to consist of spread footings of

reinforced concrete built on undisturbed soil at a depth

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

whichever is deeper. For dwellings with basements,

the foundation is assumed to consist of spread

footings of reinforced concrete built on undisturbed soil

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

based on the soil properties that affect the capacity of

the soil to support a load without movement and on

the properties that affect excavation and construction

costs. The properties that affect the load-supporting

capacity include depth to a water table, ponding,

flooding, subsidence, linear extensibility (shrink-swell

potential), and compressibility. Compressibility is

inferred from the Unified classification. The properties

that affect the ease and amount of excavation include

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

to bedrock or a cemented pan, hardness of bedrock or

a cemented pan, and the amount and size of rock

fragments.

Small commercial buildings are structures that are

less than three stories high and do not have

basements. The foundation is assumed to consist of

spread footings of reinforced concrete built on

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

maximum frost penetration, whichever is deeper. The

ratings are based on the soil properties that affect the

capacity of the soil to support a load without

movement and on the properties that affect excavation

and construction costs. The properties that affect the

load-supporting capacity include depth to a water

table, ponding, flooding, subsidence, linear

extensibility (shrink-swell potential), and

compressibility (which is inferred from the Unified

classification). The properties that affect the ease and

amount of excavation include flooding, depth to a

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

cemented pan, hardness of bedrock or a cemented

pan, and the amount and size of rock fragments.

Local roads and streets have an all-weather surface

and carry automobile and light truck traffic all year.

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

of gravel, crushed rock, or soil material stabilized by

lime or cement; and a surface of flexible material

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

binder. The ratings are based on the soil properties

that affect the ease of excavation and grading and the

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

Table 15 shows the degree and kind of soil

limitations that affect septic tank absorption fields,

sewage lagoons, sanitary landfills, and daily cover for

landfill. The ratings are both verbal and numerical.

Rating class terms indicate the extent to which the

soils are limited by all of the soil features that affect
Henry County, Illinois 187

these uses. Not limited indicates that the soil has

features that are very favorable for the specified use.

Good performance and very low maintenance can be

expected. Somewhat limited indicates that the soil has

features that are moderately favorable for the specified

use. The limitations can be overcome or minimized by

special planning, design, or installation. Fair

performance and moderate maintenance can be

expected. Very limited indicates that the soil has one

or more features that are unfavorable for the specified

use. The limitations generally cannot be overcome

without major soil reclamation, special design, or

expensive installation procedures. Poor performance

and high maintenance can be expected.

Numerical ratings in the table indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

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

limitation (0.00).

Septic tank absorption fields are areas in which

effluent from a septic tank is distributed into the soil

through subsurface tiles or perforated pipe. Only that

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

evaluated. The ratings are based on the soil properties

that affect absorption of the effluent, construction and

maintenance of the system, and public health.

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

bedrock or a cemented pan, and flooding affect

absorption of the effluent. Stones and boulders, ice,

and bedrock or a cemented pan interfere with

installation. Subsidence interferes with installation and

maintenance. Excessive slope may cause lateral

seepage and surfacing of the effluent in downslope

areas.

Some soils are underlain by loose sand and gravel

or fractured bedrock at a depth of less than 4 feet

below the distribution lines. In these soils the

absorption field may not adequately filter the effluent,

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

ground water may become contaminated.

Sewage lagoons are shallow ponds constructed to

hold sewage while aerobic bacteria decompose the

solid and liquid wastes. Lagoons should have a nearly

level floor surrounded by cut slopes or embankments

of compacted soil. Nearly impervious soil material for

the lagoon floor and sides is required to minimize

seepage and contamination of ground water.

Considered in the ratings are slope, permeability,

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

cemented pan, flooding, large stones, and content of

organic matter.

Soil permeability is a critical property affecting the

suitability for sewage lagoons. Most porous soils

eventually become sealed when they are used as sites

for sewage lagoons. Until sealing occurs, however, the

hazard of pollution is severe. Soils that have a

permeability rate of more than 2 inches per hour are

too porous for the proper functioning of sewage

lagoons. In these soils, seepage of the effluent can

result in contamination of the ground water. 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
188 Soil Survey of

landfill should be suitable for plants. It should not have

excess sodium or salts and should not be too acid.

The surface layer generally has the best workability,

the highest content of organic matter, and the best

potential for plants. Material from the surface layer

should be stockpiled for use as the final cover.

In an area sanitary landfill, solid waste is placed in

successive layers on the surface of the soil. The waste

is spread, compacted, and covered daily with a thin

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

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

the completed landfill. The ratings in the table are

based on the soil properties that affect trafficability and

the risk of pollution. These properties include flooding,

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

and depth to bedrock or a cemented pan.

Flooding is a serious problem because it can result

in pollution in areas downstream from the landfill. If

permeability is too rapid or if fractured bedrock, a

fractured cemented pan, or the water table is close to

the surface, the leachate can contaminate the water

supply. Slope is a consideration because of the extra

grading required to maintain roads in the steeper

areas of the landfill. Also, leachate may flow along the

surface of the soils in the steeper areas and cause

difficult seepage problems.

Daily cover for landfill is the soil material that is

used to cover compacted solid waste in an area

sanitary landfill. The soil material is obtained offsite,

transported to the landfill, and spread over the waste.

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

a landfill. They are based on the soil properties that

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

moving and spreading the material over the refuse

daily during wet and dry periods. These properties

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

rock fragments, slope, depth to bedrock or a

cemented pan, reaction, and content of salts, sodium,

or lime.

Loamy or silty soils that are free of large stones and

excess gravel are the best cover for a landfill. Clayey

soils may be sticky and difficult to spread; sandy soils

are subject to wind erosion.

Slope affects the ease of excavation and of moving

the cover material. Also, it can influence runoff,

erosion, and reclamation of the borrow area.

After soil material has been removed, the soil

material remaining in the borrow area must be thick

enough over bedrock, a cemented pan, or the water

table to permit revegetation. The soil material used as

the final cover for a landfill should be suitable for

plants. It should not have excess sodium, salts, or lime

and should not be too acid.

Construction Materials

Table 16 gives information about the soils as

potential sources of reclamation material, roadfill,

topsoil, and sand. Normal compaction, minor

processing, and other standard construction practices

are assumed.

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

sources of reclamation material, roadfill, and topsoil.

The features that limit the soils as sources of these

materials are specified in the table. The numerical

ratings given after the specified features indicate the

degree to which the features limit the soils as sources

of reclamation material, roadfill, or topsoil. The lower

the number, the greater the limitation.

Reclamation material is used in areas that have

been drastically disturbed by surface mining or similar

activities. When these areas are reclaimed, layers of

soil material or unconsolidated geological material, or

both, are replaced in a vertical sequence. The

reconstructed soil favors plant growth. The ratings in

the table do not apply to quarries and other mined

areas that require an offsite source of reconstruction

material. The ratings are based on the soil properties

that affect erosion and stability of the surface and the

productive potential of the reconstructed soil. These

properties include the content of sodium, salts, and

calcium carbonate; reaction; available water capacity;

erodibility; texture; content of rock fragments; and

content of organic matter and other features that affect

fertility.

Roadfill is soil material that is excavated in one

place and used in road embankments in another

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

roadfill for low embankments, generally less than 6

feet high and less exacting in design than higher

embankments.

The ratings are for the whole soil, from the surface

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

will be mixed when the soil material is excavated and

spread.

The ratings are based on the amount of suitable

material and on soil properties that affect the ease of

excavation and the performance of the material after it

is in place. The thickness of the suitable material is a

major consideration. The ease of excavation is

affected by large stones, depth to a water table, and

slope. How well the soil performs in place after it has

been compacted and drained is determined by its

strength (as inferred from the AASHTO classification

of the soil) and linear extensibility (shrink-swell

potential).

Topsoil is used to cover an area so that vegetation
Henry County, Illinois 189

can be established and maintained. The upper 40

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

evaluated is the reclamation potential of the borrow

area. The ratings are based on the soil properties that

affect plant growth; the ease of excavating, loading,

and spreading the material; and reclamation of the

borrow area. Toxic substances, soil reaction, and the

properties that are inferred from soil texture, such as

available water capacity and fertility, affect plant

growth. The ease of excavating, loading, and

spreading is affected by rock fragments, slope, depth

to a water table, soil texture, and thickness of suitable

material. Reclamation of the borrow area is affected by

slope, depth to a water table, rock fragments, depth to

bedrock or a cemented pan, and toxic material.

The surface layer of most soils is generally preferred

for topsoil because of its organic matter content. Organic

matter greatly increases the absorption and retention of

moisture and nutrients for plant growth.

Sand and gravel are natural aggregates suitable for

commercial use with a minimum of processing. They

are used in many kinds of construction. Specifications

for each use vary widely. Because all of the soils in

Henry County are poor sources of gravel, this

interpretation is not included in table 16. In the table,

only the likelihood of finding material in suitable

quantity is evaluated. The suitability of the material for

specific purposes is not evaluated, nor are factors that

affect excavation of the material. The properties used

to evaluate the soil as a source of sand are gradation

of grain sizes (as indicated by the Unified classification

of the soil), the thickness of suitable material, and the

content of rock fragments. If the bottom layer of the

soil contains sand, the soil is considered a likely

source regardless of thickness. The assumption is that

the sand layer below the depth of observation exceeds

the minimum thickness.

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

sources of sand. A rating of good or fair means that

the source material is likely to be in or below the soil.

The bottom layer and the thickest layer of the soils are

assigned numerical ratings. These ratings indicate the

likelihood that the layer is a source of sand. The

number 0.00 indicates that the layer is a poor source.

The number 1.00 indicates that the layer is a good

source. A number between 0.00 and 1.00 indicates the

degree to which the layer is a likely source.

Water Management

Tables 17a and 17b 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

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
190

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.
191

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 18 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. “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

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)

Soil Properties
192 Soil Survey of

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 19 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 the table, the estimated sand content of

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

the soil material that is less than 2 millimeters in

diameter.

Silt as a soil separate consists of mineral soil

particles that are 0.002 to 0.05 millimeter in diameter.

In the table, 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 the table, 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

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
Henry County, Illinois 193

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

19, 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 19 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.

Descriptions of these groups are available in the

“National Soil Survey Handbook” (USDA, 2003).

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

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 20 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.

Water Features

Table 21 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
194 Soil Survey of

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 21 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 21 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

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 21 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 22 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
Henry County, Illinois 195

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.

Subsidence is the settlement of organic soils or of

saturated mineral soils of very low density. Subsidence

generally results from either desiccation and

shrinkage or oxidation of organic material, or both,

following drainage. Subsidence takes place gradually,

usually over a period of several years. The table shows

the expected initial subsidence, which usually is a

result of drainage, and total subsidence, which results

from a combination of factors.

Potential for frost action is the likelihood of upward

or lateral expansion of the soil caused by the formation

of segregated ice lenses (frost heave) and the

subsequent collapse of the soil and loss of strength on

thawing. Frost action occurs when moisture moves

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

density, permeability, content of organic matter, and

depth to the water table are the most important factors

considered in evaluating the potential for frost action. It

is assumed that the soil is not insulated by vegetation

or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in

winter are the most susceptible to frost action. Well

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

susceptible. Frost heave and low soil strength during

thawing cause damage to pavements and other rigid

structures.

Risk of corrosion pertains to potential soil-induced

electrochemical or chemical action that corrodes or

weakens uncoated steel or concrete. The rate of

corrosion of uncoated steel is related to such factors

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

electrical conductivity of the soil. The rate of corrosion

of concrete is based mainly on the sulfate and sodium

content, texture, moisture content, and acidity of the

soil. Special site examination and design may be

needed if the combination of factors results in a severe

hazard of corrosion. The steel or concrete in

installations that intersect soil boundaries or soil layers

is more susceptible to corrosion than the steel or

concrete in installations that are entirely within one

kind of soil or within one soil layer.

For uncoated steel, the risk of corrosion, expressed

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

class, total acidity, electrical resistivity near field

capacity, and electrical conductivity of the saturation

extract.

For concrete, the risk of corrosion also is expressed

as low, moderate, or high. It is based on soil texture,

acidity, and amount of sulfates in the saturation

extract.

Cation-exchange capacity. The total amount of

exchangeable cations that can be held by the soil,

expressed in terms of milliequivalents per 100

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

other stated pH value. The term, as applied to

soils, is synonymous with base-exchange capacity

but is more precise in meaning.

compounds making up concretions. If formed in

place, concretions of iron oxide or manganese

oxide are generally considered a type of

redoximorphic concentration.

Conservation cropping system. Growing crops in

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

manure crops of grasses and legumes, proper

tillage, adequate fertilization, and weed and pest

control.

Conservation tillage. A tillage system that does not

invert the soil and that leaves a protective amount

of crop residue on the surface throughout the year.

Consistence, soil. Refers to the degree of cohesion

and adhesion of soil material and its resistance to

deformation when ruptured. Consistence includes

resistance of soil material to rupture and to

penetration; plasticity, toughness, and stickiness of

puddled soil material; and the manner in which the

soil material behaves when subject to

compression. Terms describing consistence are

defined in the “Soil Survey Manual.”

organic matter content, and fertility and helps to

control erosion.

Cropping system. Growing crops according to a

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

volume of the stand by its age. As the stand

increases in age, the mean annual increment

continues to increase until mortality begins to

reduce the rate of increase. The point where the
Henry County, Illinois 201

stand reaches its maximum annual rate of growth

is called the culmination of the mean annual

increment.

Cutbanks cave (in tables). The walls of excavations

tend to cave in or slough.

Deferred grazing. Postponing grazing or resting

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

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

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

surface for the specified use.

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

generally a terrace, built to protect downslope

areas by diverting runoff from its natural course.

Drainage class (natural). Refers to the frequency and

duration of wet periods under conditions similar to

those under which the soil formed. Alterations of

the water regime by human activities, either

through drainage or irrigation, are not a

consideration unless they have significantly

changed the morphology of the soil. Seven

classes of natural soil drainage are recognized—

excessively drained, somewhat excessively

drained, well drained, moderately well drained,

somewhat poorly drained, poorly drained, and

very poorly drained. These classes are defined in

the “Soil Survey Manual.”

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

from an area.

Drainageway. An area of ground at a lower elevation

than the surrounding ground and in which water

collects and is drained to a closed depression or

lake or to a drainageway at a lower elevation. A

drainageway may or may not have distinctly

incised channels at its upper reaches or

throughout its course.

Eluviation. The movement of material in true solution

or colloidal suspension from one place to another

within the soil. Soil horizons that have lost material

through eluviation are eluvial; those that have

received material are illuvial.

Endosaturation. A type of saturation of the soil in

which all horizons between the upper boundary of

saturation and a depth of 2 meters are saturated.

Eolian soil material. Earthy parent material

accumulated through wind action; commonly

refers to sandy material in dunes or to loess in

blankets on the surface.

perched water table in a soil in which saturated

layers are underlain by one or more unsaturated

layers within 2 meters of the surface.

Erosion. The wearing away of the land surface by

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

such processes as gravitational creep.

Erosion (geologic). Erosion caused by geologic

processes acting over long geologic periods and

than geologic erosion, mainly as a result of human

or animal activities or of a catastrophe in nature,

such as a fire, that exposes the surface.

Escarpment. A relatively continuous and steep slope

or cliff breaking the general continuity of more

gently sloping land surfaces and resulting from

erosion or faulting. Synonym: scarp.

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

plant nutrients, in adequate amounts and in proper

balance, for the growth of specified plants when

light, moisture, temperature, tilth, and other growth

factors are favorable.

Fibric soil material (peat). The least decomposed of

all organic soil material. Peat contains a large

amount of well preserved fiber that is readily

identifiable according to botanical origin. Peat has

the lowest bulk density and the highest water

content at saturation of all organic soil material.

Field moisture capacity. The moisture content of a

soil, expressed as a percentage of the ovendry

weight, after the gravitational, or free, water has

drained away; the field moisture content 2 or 3

days after a soaking rain; also called normal field

capacity, normal moisture capacity, or capillary

capacity.

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

Flood plain. A nearly level alluvial plain that borders a

stream and is subject to flooding unless protected

artificially.

Flood-plain splay. A fan-shaped deposit or other

outspread deposit formed where an overloaded

stream breaks through a levee (natural or artificial)

and deposits its material (commonly coarse

grained) on the flood plain.

Footslope. The position that forms the inner, gently

inclined surface at the base of a hillslope. In

profile, footslopes are commonly concave. A

footslope is a transition zone between upslope

sites of erosion and transport (shoulders and

backslopes) and downslope sites of deposition

(toeslopes).

covered by continental or alpine glaciers and that

are at a higher elevation than the flood plain.

Glaciofluvial deposits (geology). Material moved by

glaciers and subsequently sorted and deposited

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

waterway, typically broad and shallow, seeded to

grass as protection against erosion. Conducts

surface water away from cropland.

much as 3 inches (2 millimeters to 7.6

centimeters) in diameter. An individual piece is a

pebble.

percent, by volume, rounded or angular rock

fragments, not prominently flattened, as much as

3 inches (7.6 centimeters) in diameter.

crop grown to be plowed under in an early stage

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

consisting of a laterally concave area of a hillside,

especially at the head of a drainageway. The

overland waterflow is converging.

Hemic soil material (mucky peat). Organic soil

material intermediate in degree of

decomposition between the less decomposed

fibric material and the more decomposed sapric

material.

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

the surface, having distinct characteristics

produced by soil-forming processes. In the

identification of soil horizons, an uppercase letter

represents the major horizons. Numbers or

lowercase letters that follow represent

subdivisions of the major horizons. An explanation

of the subdivisions is given in the “Soil Survey

Manual.” The major horizons of mineral soil are as

follows:

O horizon.—An organic layer of fresh and

decaying plant residue.

A horizon.—The mineral horizon at or near the

surface in which an accumulation of humified

organic matter is mixed with the mineral material.

Also, a plowed surface horizon, most of which was

originally part of a B horizon.

E horizon.—The mineral horizon in which the main

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

some combination of these.

B horizon.—The mineral horizon below an A

horizon. The B horizon is in part a layer of

transition from the overlying A to the underlying C

horizon. The B horizon also has distinctive

characteristics, such as (1) accumulation of clay,

sesquioxides, humus, or a combination of these;

(2) prismatic or blocky structure; (3) redder or
Henry County, Illinois 203

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

a combination of these.

C horizon.—The mineral horizon or layer,

excluding indurated bedrock, that is little affected

by soil-forming processes and does not have the

properties typical of the overlying soil material.

The material of a C horizon may be either like or

unlike that in which the solum formed. If the

material is known to differ from that in the solum,

an Arabic numeral, commonly a 2, precedes the

letter C.

Cr horizon.—Soft, consolidated bedrock beneath

the soil.

R layer.—Consolidated bedrock beneath the soil.

The bedrock commonly underlies a C horizon, but

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

Humus. The well decomposed, more or less stable

part of the organic matter in mineral soils.

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.

Illuviation. The movement of soil material from one

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

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

content of iron and manganese oxide because of

chemical reduction and removal, but having a clay

content similar to that of the adjacent matrix. A

type of redoximorphic depletion.

Irrigation. Application of water to soils to assist in

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.

soil.

Percolation. The movement of water through the soil.

Permeability. The quality of the soil that enables water

or air to move downward through the profile. The

rate at which a saturated soil transmits water is

accepted as a measure of this quality. In soil

physics, the rate is referred to as “saturated

hydraulic conductivity,” which is defined in the “Soil

Survey Manual.” In line with conventional usage in

the engineering profession and with traditional

usage in published soil surveys, this rate of flow

continues to be expressed as “permeability.” Terms

slopes.

Taxadjuncts. Soils that cannot be classified in a

series recognized in the classification system.

Such soils are named for a series they strongly

resemble and are designated as taxadjuncts to

that series because they differ in ways too small

characteristics are slightly outside the range

defined for the family of 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.

Terrace. An embankment, or ridge, constructed

across sloping soils on the contour or at a slight

angle to the contour. The terrace intercepts

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.

Table 16.--Construction Materials

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

 investigation. The numbers in the value columns range from 0.00 to 1.00. For sand, the greater the value, the

 greater the likelihood that the bottom layer or thickest layer of the soil is a source. For the other materials,

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

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.

SAL

Sandy spot A spot where the surface layer is loamy fine sand or coarser in areas

where the surface layer of the named soils in the surrounding map

unit is very fine sandy loam or finer. Typically 0.2 acre to 2.0 acres.

SAN

Severely eroded spot An area where, on the average, 75 percent or more of the original

surface layer has been lost because of accelerated erosion. Not used

in map units in which “severely eroded,” “very severely eroded,” or

“gullied” is part of the map unit name. Typically 0.2 acre to 2.0

acres.

ERO
