National Cooperative Soil Survey

This soil survey is a publication of the National Cooperative Soil Survey, a joint effort

of the United States Department of Agriculture and other Federal agencies, State

agencies including the Agricultural Experiment Stations, and local agencies. The Natural

Resources Conservation Service (formerly the Soil Conservation Service) has

leadership for the Federal part of the National Cooperative Soil Survey. 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

Henderson County Soil and Water Conservation District. The survey was partially funded

by the Illinois Department of Agriculture and by Henderson County.

Major fieldwork for this soil survey was completed in 2004. Soil names and

descriptions were approved in 2004. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 2004. The most current official data

are available on the Internet.

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.

Soil surveys contain information that affects land use planning in survey areas. They

include predictions of soil behavior for selected land uses. The surveys highlight soil

limitations, improvements needed to overcome the limitations, and the impact of

selected land uses on the environment.

Soil surveys are designed for many different users. Farmers, foresters, and

agronomists can use the surveys 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 surveys 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

surveys 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 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.

HENDERSON COUNTY is in western Illinois (fig. 1). It has an area of 253,310 acres, or

about 396 square miles. In 2000, the county had a population of 8,213. Oquawka, the

county seat, had a population of 1,639 (U.S. Department of Commerce, 2002). The

county is bounded on the west by the Mississippi River, on the north by Mercer

County, on the east by Warren County, and on the south by Hancock and McDonough

Counties.

General Nature of the Survey Area

This section provides some general information about Henderson County. It

describes history and settlement; agriculture; relief, physiography, and drainage; and

climate.

History and Settlement

Henderson County was established by law on January, 1841, after having been part

of Warren County since 1825. The first settlement in the survey area was at the

present site of Oquawka in 1827. The county was named after Henderson County,

Kentucky, which had been named after Colonel Richard Henderson. Oquawka has

been the county seat since 1841.

Agriculture

Agriculture has always been the major industry in Henderson County. The county

has a high percentage of productive soils, good transportation facilities, nearby

markets, and a favorable climate.

Although cash grain farming has increased, most of Henderson County is well

adapted to combination grain and livestock farming because of its sloping topography,

and a high percentage of farm income is derived from livestock and livestock products.

In 2002, the county had 392 farms that made up 201,200 acres (Illinois Agricultural

Statistics Service, 2004). The average farm size was 513 acres. Corn, soybeans, and

wheat are the major crops. In 2003, about 93,000 acres was used for corn, about

63,000 acres was used for soybeans, and about 1,600 acres was used for hay (Illinois

Agricultural Statistics Service, 2004).

Hogs and beef cattle are important animal industries. In 2003, the number of hogs

and pigs in the county was 22,000 and there were 18,400 cattle and calves (Illinois

Agricultural Statistics Service, 2004).

Relief, Physiography, and Drainage

Dr. Richard C. Anderson, retired, Department of Geology, Augustana College, helped prepare this

section.

The landscape of Henderson County consists largely of broad, gently rolling

uplands dissected by a system of parallel, west-flowing streams that are tributaries of

the Mississippi River. The county is in the northern part of the region known as the

Galesburg Plain. The flood plain along the Mississippi River, about 5 miles wide, is

along the western margin of the county. Elevations range from 800 feet above sea level

in the uplands near Raritan to 518 feet in the area along the Mississippi River at Dallas

City (fig. 2).

Deposits of glacial till indicate that the county has been covered by glacial ice

several times in the recent geologic past. More recently, it has received a cover of

wind-deposited silt and very fine sand, or loess, blown in from the flood plain along the

Mississippi River (Willman and Frye, 1970). The present landscape is almost entirely

the result of the erosion of these deposits by water.

Figure 2.—A generalized relief map of Henderson County showing the highest and lowest points

in the county. The orange dot represents the highest elevation (about 800 feet above sea

level). The blue dot represents the lowest elevation (about 518 feet above sea level).
4 Soil Survey of

The interstream areas in the uplands are remnants of a very extensive loessmantled till plain that once extended continuously across western and central Illinois

(Illinois State Geological Survey, 1979; Leighton and Brophy, 1961). Erosion has

created valleys that interrupt the continuity of this till plain and progressively modify

and eliminate the upland plains as they widen and lengthen. The upland areas are long

and narrow between the west-flowing streams and range in width from less than 1 mile

in the eastern part of the county to as much as about 5 miles adjacent to a bluff along

the Mississippi River.

The degree of stream dissection is generally greater in the eastern part of the

county, near the headwaters of streams, than it is to the west, in the lower reaches of

the drainage basins near the Mississippi River. This unusual relationship is probably a

result of a decrease in the thickness and grain size of the loess from west to east,

away from the source. Because it is thinner in the east, the cover of loess is more

easily removed and the underlying glacial till more easily exposed. Removal of the

loess accentuates the degree of stream dissection, reducing the width of the

interstream uplands.

The loess not only is thicker to the west but also is coarser grained and thus more

porous and less conducive to surface runoff and stream dissection. Also, geological

evidence suggests that the period of stream dissection began while the loess was still

accumulating. The accumulating loess may have inhibited stream dissection to a

greater degree to the west, close to the source area, than it did to the east. The

uplands slope generally westward from an elevation of about 800 feet in the east to

518 feet in the west (fig. 2).

The streams in Henderson County are noteworthy because they are strikingly

parallel and because their valleys are oriented from east to west. The origin of this

pattern is unknown. The pattern may be inherited from the configuration of the

underlying bedrock surface, it may reflect the initial slopes on the till plain, or it may be

related to initial variations in the thickness of the loess deposits. These are only a few

of the more obvious possible explanations. The major streams, namely Henderson

Creek, South Henderson Creek, Ellison Creek, and Honey Creek, are parallel, as are

their tributaries. Furthermore, there is marked asymmetry in the arrangement of the

tributaries. They are longer and more numerous on the north sides of the major streams.

Nearly level bottom land is along all of the streams in the county. In general, the

soils in these areas are poorly drained, are often flooded, and may be covered by

standing water for several weeks during wet years. In contrast, only the lowest of the

terraces are flooded, and then only during the most severe floods.

The flood plain along the Mississippi River makes up the western extremity of the

county. Only parts of this flood plain are subject to flooding. These are the areas on the

bottom land upstream from Dallas City and along the lower reaches of Ellison Creek

and Honey Creek. The parts subjected to flooding make up less than half of the flood

plain area in the county. Elsewhere, the flood plain consists of a sandy terrace at an

elevation of 570 to 580 feet above sea level and about 40 feet above normal river

levels. Unlike the terraces along the other streams in the county, this terrace is

depositional, a result of sand washing downriver from the melting terminus of the

continental glacier far to the north. Remnants of this terrace also are along Henderson

Creek for a few miles upstream from the point where these streams enter the flood

plain along the Mississippi River. In a few places, most notably around Oquawka, the

surface of the terrace has been blown into dunes by the wind.

Climate

Henderson County is cold in winter. In summer it generally is hot, but there are

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
Henderson County, Illinois 5

warm moist air moves in from the south. The amount of annual rainfall usually is

adequate for corn, soybeans, and small grain.

Table 1 gives data on temperature and precipitation for the survey area as recorded

at Monmouth 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 about 27 degrees F and the average daily

minimum temperature is 18.3 degrees. The lowest temperature on record, which

occurred at Monmouth on January 7, 1910, is -31 degrees. In summer, the average

temperature is about 73.3 degrees and the average daily maximum temperature is

84.7 degrees. The highest recorded temperature, which occurred in Monmouth on July

12, 1936, is 108 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 38.31 inches. Of this total, about 24.08 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 12.7 inches. The heaviest 1-day rainfall on record is 6.53

inches. Thunderstorms occur on about 50 days each year, and most occur in summer.

The average seasonal snowfall is 28.4 inches. On average, 49 days of the year have at

least 1 inch of snow on the ground. The number of such days, however, 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 the survey area, which is in Major Land Resource Areas 108B

and 115C (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, 2006). Map unit design and the detailed soil

descriptions are based on the occurrence of each soil throughout the MLRA. This soil

survey updates a survey of Henderson County published in 1956 (Veale and Wascher,

1956) and provides the soil information on USGS 7.5-minute Digital Ortho Quad

sheets for use in future geographic information systems.

The information in this survey 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; and the kinds of crops and native plants. 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 of

landform or with a segment of the landform. By observing the soils and miscellaneous

areas in the survey area and relating their position to specific segments of the
6

landform, soil scientists develop a concept, or model, of how the soils were formed.

Thus, during mapping, this model enables the soil scientist to predict with a

considerable degree of accuracy the kind of soil or miscellaneous area at a specific

location on the landform.

Commonly, individual soils on the landscape merge into one another as their

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

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

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

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

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

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

noted 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. Some interpretations are

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

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

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

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

field or plot experiments on the same kinds of soil.

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

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

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

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

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

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

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

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

of an improved 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.

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 both 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 (Jenny, 1941).

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

limits of chemical and mineralogical composition of the soil. The properties of the

parent material vary greatly, sometimes within small areas, depending on how the

material was deposited. Some of the parent materials in Henderson County were

deposited by wind, by glaciers, or by meltwater from the glaciers. In some areas the

soils have subsequently been reworked and redeposited by water and wind. The

parent materials in the county are loess, glacial till, outwash, eolian deposits,

lacustrine deposits, alluvium, and residuum, or material weathered from bedrock.

Peoria loess is the major parent material in Henderson County. The Mississippi

River Valley was the main source of the loess. Wind picked up particles of silt from the

valley floor and redeposited them in the uplands. The loess is about 30 feet thick on

nearly level uplands near bluffs. Osco soils are examples of soils that formed in loess.

These soils typically are medium textured or moderately fine textured and have well

developed structure.

Glacial till is material that was laid down directly by glaciers with a minimum of

water action. It consists of particles of different sizes. The small pebbles in glacial till

have sharp corners, indicating that they have not been worn by water.

The glacial till in Henderson County is pre-Wisconsinan in age. A clayey paleosol

that formed in till is near the head of many small drainageways leading from upland

watershed divides. Glacial till also is common in the central part of the county. Atlas

soils formed in till that has a paleosol. Loamy till dominates the lower side slopes along

small drainageways and the slopes along many of the larger drainageways. Hickory

soils are examples of soils that formed in loamy till.

Formation and Classification of

the Soils
8 Soil Survey of

Outwash was deposited by running water from melting glaciers. The size of the

particles that make up outwash material varies according to the speed of the water

that carried them. When the water slowed, 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 similar sized particles,

such as silt loam, sandy loam, and sand. Dickinson soils are examples of soils that

formed in loamy and sandy outwash that has been reworked by the wind.

Eolian deposits are sediments deposited by the wind. Coloma soils formed in eolian

deposits.

Lacustrine material was deposited from still or ponded glacial meltwater. Because

the coarser fragments dropped out of moving water as outwash, only the finer

particles, such as very fine sand, silt, and clay, remained to settle out in the still water.

In Henderson County the lacustrine deposits are clayey. Niota soils are examples of

soils that formed partly in these deposits.

Alluvial material was deposited by the floodwater of present streams in recent time.

This material varies in texture, depending on the speed of water from which it was

deposited. Sawmill and Radford soils are examples of alluvial soils.

The limestone bedrock in Henderson County generally is buried by loess, glacial till,

outwash, and alluvium. Along side slopes on deeply dissected uplands, however,

limestone residuum is a parent material. Dunbarton soils formed partly in this residuum.

Living Organisms

Plants are the principal living organisms affecting the soils in Henderson 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 material 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 examples of soils that formed under forest vegetation.

Muscatune soils are examples of soils that formed under prairie vegetation.

Climate

Climate is an important factor in the formation of soils. It influences the kinds 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 Henderson 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 Henderson County, the
Henderson County, Illinois 9

slopes dominantly range from 0 to 60 percent. Natural soil drainage classes range

from well drained on upland 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. Seaton

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 a dry climate.

The soils in Henderson County range from young to mature. Most of the soils on

uplands are moderately developed.

Classification of the Soils

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

six categories (Soil Survey Staff, 1999 and 2003). Beginning with the broadest, these

categories are the order, suborder, great group, subgroup, family, and series.

Classification is based on soil properties observed in the field or inferred from those

observations or from laboratory measurements. Table 4 shows the classification of the

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

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

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

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

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

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

that reflect the most important variables within the orders. The last syllable in the name

of a suborder indicates the order. An example is 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. An example is Typic Endoaquolls.
10

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.
11

In this section, arranged in alphabetical order, each soil series recognized in the

survey area is described. Each series description is followed by descriptions of the

associated detailed soil map units.

Characteristics of the soil and the material in which it formed are identified for each

soil series. A pedon, a small three-dimensional area of soil, that is typical of the series

in the survey area is described. The detailed description of each soil horizon follows

standards in the “Soil Survey Manual” (Soil Survey Division Staff, 1993). Many of the

technical terms used in the descriptions are defined in “Soil Taxonomy” (Soil Survey

Staff, 1999) and in “Keys to Soil Taxonomy” (Soil Survey Staff, 2003). Unless otherwise

stated, colors in the descriptions are for moist soil. Following the pedon description is

the range of important characteristics of the soils in the series.

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

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

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

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

More information about each map unit is given under the headings “Use and

Management of the Soils” and “Soil Properties.”

A map unit delineation on a soil map represents an area dominated by one or more

major kinds of soil or miscellaneous areas. A map unit is identified and named

according to the taxonomic classification of the dominant soils. Within a taxonomic

class there are precisely defined limits for the properties of the soils. On the

landscape, however, the soils are natural phenomena, and they have the characteristic

variability of all natural phenomena. Thus, the range of some observed properties may

extend beyond the limits defined for a taxonomic class. Areas of soils of a single

taxonomic class rarely, if ever, can be mapped without including areas of other

taxonomic classes. Consequently, every map unit is made up of the soils or

miscellaneous areas for which it is named and some minor components that belong to

taxonomic classes other than those of the major soils.

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

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

noncontrasting, or similar, components. They may or may not be mentioned in a

particular map unit description. Other minor components, however, have properties

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

management. These are called contrasting, or dissimilar, components. They generally

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

Some small areas of strongly contrasting soils or miscellaneous areas are identified by

a special symbol on the maps. The contrasting components are mentioned in the map

unit descriptions. A few areas of minor components may not have been observed, and

consequently they are not mentioned in the descriptions, especially where the pattern

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

soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the

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

taxonomic classes but rather to separate the landscape into landforms or landform

segments that have similar use and management requirements. The delineation of

Soil Series and Detailed Soil Map

Units
12 Soil Survey 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 the principal hazards

and limitations to be considered in planning for specific uses.

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

differences in texture of the surface layer, all the soils of a series have major horizons

that are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness,

salinity, degree of erosion, and other characteristics that affect their use. On the basis

of such differences, a soil series is divided into soil phases. Most of the areas shown

on the detailed soil maps are phases of soil series. The name of a soil phase

commonly indicates a feature that affects use or management. For example, Fayette

silt loam, 5 to 10 percent slopes, eroded, is a phase of the Fayette series.

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

These map units are called complexes. A complex consists of two or more soils or

miscellaneous areas in such an intricate pattern or in such small areas that they

cannot be shown separately on the maps. The pattern and proportion of the soils or

miscellaneous areas are somewhat similar in all areas. Rozetta-Elco silt loams, 10 to

18 percent slopes, eroded, is an example.

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

and support little or no vegetation. Pits, quarries, is an example.

Table 5 gives the acreage and proportionate extent of each map unit. Other tables

give properties of the soils and the limitations, capabilities, and potentials for many

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

miscellaneous areas.

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

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

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

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

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

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

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

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

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

crops and pasture; as 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, and 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

Use and Management of the Soils
182 Soil Survey of

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.

Yields per Acre

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 map units in the survey area also

is shown in the table.

The yields are based mainly on the experience and records of farmers,

conservationists, and extension agents (Olsen and others, 2000a and 2000b).

Available yield data from nearby counties and results of field trials and demonstrations

also are considered (Fehrenbacher and others, 1978).

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 (fig. 9), and protection from flooding; the proper planting and seeding rates;

suitable high-yielding crop varieties; appropriate and timely tillage; control of weeds,

plant diseases, and harmful insects; favorable soil reaction and optimum levels of

nitrogen, phosphorus, potassium, and trace elements for each crop; effective use of

crop residue, barnyard manure, and green manure crops; and harvesting that ensures

the smallest possible loss.

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

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

developed. The productivity of a given soil compared with that of other soils, however,

is not likely to change.

Crops other than those shown in table 6 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 and Hayland Interpretations

Under good management, proper grazing is essential for the production of highquality 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 pasture renovation also are important management practices.
Henderson County, Illinois 183

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 the Cooperative

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

in the yields table.

Land Capability Classification

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

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

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

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

grouping the soils do not include major and generally expensive landforming that

would change slope, depth, or other characteristics of the soils, nor do they include

possible but unlikely major reclamation projects. Capability classification is not a

substitute for interpretations designed to show suitability and limitations of groups of

soils for forestland or for engineering purposes.

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

class, subclass, and unit (USDA, 1961). 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. The classes are defined as follows:

Figure 9.—No-till practices leave crop residue on the surface and help to control erosion.
184 Soil Survey of

Class 1 soils have slight limitations that restrict their use.

Class 2 soils have moderate limitations that restrict the choice of plants or that

require moderate conservation practices.

Class 3 soils have severe limitations that restrict the choice of plants or that require

special conservation practices, or both.

Class 4 soils have very severe limitations that restrict the choice of plants or that

require very careful management, or both.

Class 5 soils are subject to little or no erosion but have other limitations, impractical

to remove, that restrict their use mainly to pasture, forestland, or wildlife habitat.

Class 6 soils have severe limitations that make them generally unsuitable for

cultivation and that restrict their use mainly to pasture, forestland, or wildlife habitat.

Class 7 soils have very severe limitations that make them unsuitable for cultivation

and that restrict their use mainly to grazing, forestland, or wildlife habitat.

Class 8 soils and miscellaneous areas have limitations that preclude commercial

plant production and that restrict their use to recreational purposes, wildlife habitat,

watershed, or esthetic purposes.

Capability subclasses are soil groups within one 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 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.

In class 1 there are no subclasses 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, or wildlife habitat.

The capability classification of the soils in this survey area is given in the section

“Soil Series and Detailed Soil Map Units” and in the yields table.

Prime Farmland

Prime farmland is one of several kinds of important farmland defined by the U.S.

Department of Agriculture. It is of major importance in meeting the Nation’s short- and

long-range needs for food and fiber. Because the supply of high-quality farmland is

limited, the U.S. Department of Agriculture recognizes that responsible levels of

government, as well as individuals, should encourage and facilitate the wise use of our

Nation’s prime farmland.

Prime farmland, as defined by the U.S. Department of Agriculture, is land that has

the best combination of physical and chemical characteristics for producing food, feed,

forage, fiber, and oilseed crops and is available for these uses. It could be cultivated

land, pastureland, forestland, or other land, but it is not urban or built-up land or water

areas. The soil qualities, growing season, and moisture supply are those needed for

the soil to economically produce sustained high yields of crops when proper

management, including water management, and acceptable farming methods are

applied. In general, prime farmland has an adequate and dependable supply of

moisture from precipitation or irrigation, a favorable temperature and growing season,

acceptable acidity or alkalinity, an acceptable salt and sodium content, and few or no

rocks. It is permeable to water and air. It is not excessively erodible or saturated with

water for long periods, and it either is not frequently flooded during the growing season

or is protected from flooding. Slope ranges mainly from 0 to 6 percent. More detailed

information about the criteria for prime farmland is available at the local office of the

Natural Resources Conservation Service.
Henderson County, Illinois 185

A recent trend in land use in some parts of the survey area has been the loss of

some prime farmland to industrial and urban uses. The loss of prime farmland to other

uses puts pressure on marginal lands, which generally are more erodible, droughty,

and less productive and cannot be easily cultivated.

About 134,360 acres, or about 53 percent of the survey area, meets the

requirements for prime farmland.

The map units in the survey area that are considered 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 list, measures that overcome a hazard or limitation, such as

flooding, wetness, and droughtiness, are needed. Onsite evaluation is needed to

determine whether or not the hazard or limitation has been overcome by corrective

measures. The extent of each listed map unit is shown in table 5. The location is

shown on the detailed soil maps. The soil qualities that affect use and management

are described under the heading “Soil Series and Detailed Soil Map Units.”

Hydric Soils

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 all 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, under natural conditions, are either saturated or

inundated long enough during the growing season to support the growth and

reproduction of hydrophytic vegetation (fig. 10).

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, 2002). These criteria

are used to identify map unit components that normally are 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,

2003) and in the “Soil Survey Manual” (Soil Survey Division Staff, 1993).

If soils are wet enough for a long enough period of time 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 are specified in “Field Indicators of Hydric Soils in the

United States” (Hurt and others, 2002).

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.

Map units that are dominantly made up of hydric soils may have small areas, or

inclusions, of nonhydric soils in the higher positions on the landform, and map units
186 Soil Survey of

dominantly made up of nonhydric soils may have inclusions of hydric soils in the lower

positions on the landform. Table 8 lists the map units that include hydric soils, either as

major components or as inclusions. The hydric soils listed in the table meet the

definition of a hydric soil and have at least one of the hydric soil indicators. This list can

help in planning land uses; however, onsite investigation is recommended to determine

the hydric soils on a specific site (National Research Council, 1995; Hurt and others,

2002).

The criteria for hydric soils are represented by codes in the table (for example,

2B3). Definitions for the codes are as follows:

1. All Histels except for Folistels, and Histosols except for Folists.

2. Soils in Aquic suborders, great groups, or subgroups, Albolls suborder, Historthels

great group, Histoturbels great group, Pachic subgroups, or Cumulic subgroups

that:

A. are somewhat poorly drained and have a water table at the surface (0.0 feet)

during the growing season, or

B. are poorly drained or very poorly drained and have either:

1) a water table at the surface (0.0 feet) during the growing season if textures

are coarse sand, sand, or fine sand in all layers within a depth of 20 inches,

or

2) a water table at a depth of 0.5 foot or less during the growing season if

permeability is equal to or greater than 6.0 in/hr in all layers within a depth

of 20 inches, or

3) a water table at a depth of 1.0 foot or less during the growing season if

permeability is less than 6.0 in/hr in any layer within a depth of 20 inches.

Figure 10.—Wetland vegetation in an area of Fluvaquents.
Henderson County, Illinois 187

3. Soils that are frequently ponded for long or very long duration during the growing

season.

4. Soils that are frequently flooded for long or very long duration during the growing

season.

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 9 shows the height that locally grown trees and shrubs are expected to reach

in 20 years on soils in the survey area. The estimates in the table are based on

measurements and observation of established plantings that have been given

adequate care. They can be used as a guide in planning windbreaks and screens.

Additional information on planning windbreaks and screens and planting and caring for

trees and shrubs can be obtained from the local office of the Natural Resources

Conservation Service or of the Cooperative Extension Service or from a commercial

nursery.

Forestland Productivity and Management

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 forest

management.

Forestland Productivity

In table 10, 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 (http://soils.usda.gov).

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, even-aged, unmanaged stand.

Trees to manage are those that are preferred for planting, seeding, or natural

regeneration and those that remain in the stand after thinning or partial harvest.

Forestland Management

In tables 11a through 11e, interpretive ratings are given for various aspects of forest

management. The ratings are both verbal and numerical.
188 Soil Survey of

Some rating class terms indicate the degree to which the soils are suited to a

specified forest management practice. Well suited indicates that the soil has features

that are favorable for the specified practice and has no limitations. Good performance

can be expected, and little or no maintenance is needed. Moderately suited indicates

that the soil has features that are moderately favorable for the specified practice. One

or more soil properties are less than desirable, and fair performance can be expected.

Some maintenance is needed. Poorly suited indicates that the soil has one or more

properties that are unfavorable for the specified practice. Overcoming the unfavorable

properties requires special design, extra maintenance, and costly alteration. Unsuited

indicates that the expected performance of the soil is unacceptable for the specified

practice or that extreme measures are needed to overcome the undesirable soil

properties.

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

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

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

on the specified forest management practice (1.00) and the point at which the soil

feature is not a limitation (0.00).

Rating class terms for seedling mortality are expressed as low, moderate, and high.

Where these terms are used, the numerical ratings indicate gradations between the

point at which the potential for 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 forest management practices. More detailed information about the criteria

used in the ratings is available in the “National Forestry Manual,” which is available

in local offices of the Natural Resources Conservation Service or on the Internet

(http://soils.usda.gov).

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 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
Henderson County, Illinois 189

productivity and off-site damage are likely, and erosion-control measures are costly

and generally impractical.

Ratings in the column hazard of erosion on roads and trails are based on the soil

erodibility factor K, slope, and content of rock fragments. The ratings apply to

unsurfaced roads and trails. The hazard is described as slight, moderate, or severe. A

rating of slight indicates that little or no erosion is likely; moderate indicates that some

erosion is likely, that the roads or trails may require occasional maintenance, and that

simple erosion-control measures are needed; and severe indicates that significant

erosion is expected, that the roads or trails require frequent maintenance, and that

costly erosion-control measures are needed.

Ratings in the column suitability for roads (natural surface) are based on slope, rock

fragments on the surface, plasticity index, content of sand, the Unified classification,

depth to a water table, ponding, flooding, and the hazard of soil slippage. The ratings

indicate the suitability for using the natural surface of the soil for roads. The soils are

described as well suited, moderately suited, or poorly suited to this use.

Ratings in the columns suitability for hand planting and suitability for mechanical

planting are based on slope, depth to a restrictive layer, content of sand, plasticity

index, rock fragments on or below the surface, depth to a water table, and ponding.

The soils are described as well suited, moderately suited, poorly suited, or unsuited to

these methods of planting. It is assumed that necessary site preparation is completed

before seedlings are planted.

Ratings in the column suitability for use of harvesting equipment are based on

slope, rock fragments on the surface, plasticity index, content of sand, the Unified

classification, depth to a water table, and ponding. The soils are described as well

suited, moderately suited, or poorly suited to this use.

Ratings in the column suitability for mechanical site preparation (surface) are based

on slope, depth to a restrictive layer, plasticity index, rock fragments on or below the

surface, depth to a water table, and ponding. The soils are described as well suited,

poorly suited, or unsuited to this management activity. The part of the soil from the

surface to a depth of about 1 foot is considered in the ratings.

Ratings in the column suitability for mechanical site preparation (deep) are based

on slope, depth to a restrictive layer, rock fragments on or below the surface, depth to

a water table, and ponding. The soils are described as well suited, poorly suited, or

unsuited to this management activity. The part of the soil from the surface to a depth of

about 3 feet is considered in the ratings.

Ratings in the column potential for seedling mortality are based on flooding,

ponding, depth to a water table, content of lime, reaction, salinity, available water

capacity, soil moisture regime, soil temperature regime, aspect, and slope. The soils

are described as having a low, moderate, or high potential for seedling mortality.

Recreation

The soils of the survey area are rated in tables 12a and 12b 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.
190 Soil Survey of

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 12a and 12b can be supplemented by other information in

this survey, for example, interpretations for building site development, construction

materials, sanitary facilities, and water management.

Camp areas require site preparation, such as shaping and leveling the tent and

parking areas, stabilizing roads and intensively used areas, and installing sanitary

facilities and utility lines. Camp areas are subject to heavy foot traffic and some

vehicular traffic. The ratings are based on the soil properties that affect the ease of

developing camp areas and the performance of the areas after development. Slope,

stoniness, and depth to bedrock or a cemented pan are the main concerns affecting

the development of camp areas. The soil properties that affect the performance of the

areas after development are those that influence trafficability and promote the growth

of vegetation, especially in heavily used areas. For good trafficability, the surface of

camp areas should absorb rainfall readily, remain firm under heavy foot traffic, and not

be dusty when dry. The soil properties that influence trafficability are texture of the

surface layer, depth to a water table, ponding, flooding, permeability, and large stones.

The soil properties that affect the growth of plants are depth to bedrock or a cemented

pan, permeability, and toxic substances in the soil.

Picnic areas are subject to heavy foot traffic. Most vehicular traffic is confined to

access roads and parking areas. The ratings are based on the soil properties that

affect the ease of developing picnic areas and that influence trafficability and the

growth of vegetation after development. Slope and stoniness are the main concerns

affecting the development of picnic areas. For good trafficability, the surface of picnic

areas should absorb rainfall readily, remain firm under heavy foot traffic, and not be

dusty when dry. The soil properties that influence trafficability are texture of the surface

layer, depth to a water table, ponding, flooding, permeability, and large stones. The soil

properties that affect the growth of plants are depth to bedrock or a cemented pan,

permeability, and toxic substances in the soil.

Playgrounds require soils that are nearly level, are free of stones, and can

withstand intensive foot traffic. The ratings are based on the soil properties that affect

the ease of developing playgrounds and that influence trafficability and the growth of

vegetation after development. Slope and stoniness are the main concerns affecting the

development of playgrounds. For good trafficability, the surface of the playgrounds

should absorb rainfall readily, remain firm under heavy foot traffic, and not be dusty

when dry. The soil properties that influence trafficability are texture of the surface layer,

depth to a water table, ponding, flooding, permeability, and large stones. The soil

properties that affect the growth of plants are depth to bedrock or a cemented pan,

permeability, and toxic substances in the soil.

Paths and trails for hiking and horseback riding should require little or no slope

modification through cutting and filling. The ratings are based on the soil properties
Henderson County, Illinois 191

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 13, the soils in the survey area are rated according to their potential for

providing habitat for various kinds of wildlife. This information can be used 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
192 Soil Survey of

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 bluestem, indiangrass,

blueberry, goldenrod, lambsquarters, 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, box elder, birch, maple, green ash, willow,

and American elm.

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,

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, cattails, 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, 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, and white-tailed deer.

Habitat for wetland wildlife consists of open, marshy or swampy shallow water

areas. Some of the wildlife attracted to such areas are ducks, geese, herons, bitterns,

rails, kingfishers, muskrat, otter, mink, and beaver.

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 (fig. 11). 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
Henderson County, Illinois 193

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

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
Henderson County, Illinois 195

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 (shrink-swell

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

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

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

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

Depth to bedrock or a cemented pan, hardness of bedrock or a cemented pan, the

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

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

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

machinery. Soil texture, depth to the water table, and linear extensibility (shrink-swell

potential) influence the resistance to sloughing.

Lawns and landscaping require soils on which turf and ornamental trees and shrubs

can be established and maintained. Irrigation is not considered in the ratings. The

ratings are based on the soil properties that affect plant growth and trafficability after

vegetation is established. The properties that affect plant growth are reaction; depth to

a water table; ponding; depth to bedrock or a cemented pan; the available water

capacity in the upper 40 inches; the content of salts, sodium, or calcium carbonate;

and sulfidic materials. The properties that affect trafficability are flooding, depth to a

water table, ponding, slope, stoniness, and the amount of sand, clay, or organic matter

in the surface layer.

Sanitary Facilities

Tables 15a and 15b show the degree and kind of soil limitations that affect septic

tank absorption fields, sewage lagoons, sanitary landfills, and daily cover for landfill.

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

which the soils are limited by all of the soil features that affect these uses. Not limited

indicates that the soil has features that are very favorable for the specified use. Good

performance and very low maintenance can be expected. Somewhat limited indicates

that the soil has features that are moderately favorable 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).
196 Soil Survey of

Septic tank absorption fields are areas in which effluent from a septic tank is

distributed into the soil through subsurface tiles or perforated pipe. Only that part of the

soil between depths of 24 and 60 inches is evaluated. The ratings are based on the

soil properties that affect absorption of the effluent, construction and maintenance of

the system, and public health. Permeability, depth to a water table, ponding, depth to

bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and

boulders, ice, and bedrock or a cemented pan interfere with installation. Subsidence

interferes with installation and maintenance. Excessive slope may cause lateral

seepage and surfacing of the effluent in downslope areas.

Some soils are underlain by loose sand and gravel or fractured bedrock at a depth

of less than 4 feet below the distribution lines. In these soils the absorption field may

not adequately filter the effluent, particularly when the system is new. As a result, the

ground water may become contaminated.

Sewage lagoons are shallow ponds constructed to hold sewage while aerobic

bacteria decompose the solid and liquid wastes. Lagoons should have a nearly level

floor surrounded by cut slopes or embankments of compacted soil. Nearly impervious

soil material for the lagoon floor and sides is required to minimize seepage and

contamination of ground water. Considered in the ratings are slope, permeability, depth

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

and content of organic matter.

Soil permeability is a critical property affecting the suitability for sewage lagoons.

Most porous soils eventually become sealed when they are used as sites for sewage

lagoons. Until sealing occurs, however, the hazard of pollution is severe. Soils that

have a permeability rate of more than 2 inches per hour are too porous for the proper

functioning of sewage lagoons. In these soils, seepage of the effluent can result in

contamination of the ground water. Ground-water contamination is also a hazard if

fractured bedrock is within a depth of 40 inches, if the water table is high enough to

raise the level of sewage in the lagoon, or if floodwater overtops the lagoon.

A high content of organic matter is detrimental to proper functioning of the lagoon

because it inhibits aerobic activity. Slope, bedrock, and cemented pans can cause

construction problems, and large stones can hinder compaction of the lagoon floor. If

the lagoon is to be uniformly deep throughout, the slope must be gentle enough and

the soil material must be thick enough over bedrock or a cemented pan to make land

smoothing practical.

A trench sanitary landfill is an area where solid waste is placed in successive layers

in an excavated trench. The waste is spread, compacted, and covered daily with a thin

layer of soil excavated at the site. When the trench is full, a final cover of soil material

at least 2 feet thick is placed over the landfill. The ratings in the table are based on the

soil properties that affect the risk of pollution, the ease of excavation, trafficability, and

revegetation. These properties include permeability, depth to bedrock or a cemented

pan, depth to a water table, ponding, slope, flooding, texture, stones and boulders,

highly organic layers, soil reaction, and content of salts and sodium. Unless otherwise

stated, the ratings apply only to that part of the soil within a depth of about 6 feet. For

deeper trenches, onsite investigation may be needed.

Hard, nonrippable bedrock, creviced bedrock, or highly permeable strata in or

directly below the proposed trench bottom can affect the ease of excavation and the

hazard of ground-water pollution. Slope affects construction of the trenches and the

movement of surface water around the landfill. It also affects the construction and

performance of roads in areas of the landfill.

Soil texture and consistence affect the ease with which the trench is dug and the

ease with which the soil can be used as daily or final cover. They determine the

workability of the soil when dry and when wet. Soils that are plastic and sticky when
Henderson County, Illinois 197

wet are difficult to excavate, grade, or compact and are difficult to place as a uniformly

thick cover over a layer of refuse.

The soil material used as the final cover for a trench landfill should be suitable for

plants. It should not have excess sodium or salts and should not be too acid. The

surface layer generally has the best workability, the highest content of organic matter,

and the best potential for plants. Material from the surface layer should be stockpiled

for use as the final cover.

In an area sanitary landfill, solid waste is placed in successive layers on the surface

of the soil. The waste is spread, compacted, and covered daily with a thin layer of soil

from a source away from the site. A final cover of soil material at least 2 feet thick is

placed over the completed landfill. The ratings in the table are based on the soil

properties that affect trafficability and the risk of pollution. These properties include

flooding, permeability, depth to a water table, ponding, slope, and depth to bedrock or

a cemented pan.

Flooding is a serious problem because it can result in pollution in areas

downstream from the landfill. If permeability is too rapid or if fractured bedrock, a

fractured cemented pan, or the water table is close to the surface, the leachate can

contaminate the water supply. Slope is a consideration because of the extra grading

required to maintain roads in the steeper areas of the landfill. Also, leachate may flow

along the surface of the soils in the steeper areas and cause difficult seepage

problems.

Daily cover for landfill is the soil material that is used to cover compacted solid

waste in an area sanitary landfill. The soil material is obtained offsite, transported to

the landfill, and spread over the waste. The ratings in the table also apply to the final

cover for a landfill. They are based on the soil properties that affect workability, the

ease of digging, and the ease of moving and spreading the material over the refuse

daily during wet and dry periods. These properties include soil texture, depth to a

water table, ponding, rock fragments, slope, depth to bedrock or a cemented pan,

reaction, and content of salts, sodium, or lime.

Loamy or silty soils that are free of large stones and excess gravel are the best

cover for a landfill. Clayey soils may be sticky and difficult to spread; sandy soils are

subject to wind erosion.

Slope affects the ease of excavation and of moving the cover material. Also, it can

influence runoff, erosion, and reclamation of the borrow area.

After soil material has been removed, the soil material remaining in the borrow area

must be thick enough over bedrock, a cemented pan, or the water table to permit

revegetation. The soil material used as the final cover for a landfill should be suitable

for plants. It should not have excess sodium, salts, or lime and should not be too acid.

Construction Materials

Tables 16a and 16b give information about the soils as potential sources of sand,

reclamation material, roadfill, and topsoil. Normal compaction, minor processing, and

other standard construction practices are assumed.

Sand is a natural aggregate suitable for commercial use with a minimum of

processing. It is used in many kinds of construction. Specifications for each use vary

widely. In table 16a, 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
198 Soil Survey of

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 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.

In table 16b, 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 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.
Henderson County, Illinois 199

Water Management

Tables 17a, 17b, and 17c 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; tile drains and underground outlets; and irrigation. 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).

Table 17a

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

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

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

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

area.

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

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

overflow. Embankments that have zoned construction (core and shell) are not

considered. In this table, the soils are rated as a source of material for embankment

fill. The ratings apply to the soil material below the surface layer to a depth of about 5

feet. It is assumed that soil layers will be uniformly mixed and compacted during

construction.

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

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

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

needed to determine these properties.

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

and have favorable compaction characteristics. Unfavorable features include less than

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

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

trafficability.

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

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

only by surface runoff and embankment ponds that impound water 3 feet or more

above the original surface. Excavated ponds are affected by depth to a permanent

water table, permeability of the aquifer, and quality of the water as inferred from the

salinity of the soil. Depth to bedrock and the content of large stones affect the ease of

excavation.
200 Soil Survey of

Table 17b

Grassed waterways and surface drains are natural or constructed channels,

generally broad and shallow, that conduct surface water to outlets at a nonerosive

velocity (fig. 12). 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.

Figure 12.—Grassed waterways and drop structures help to convey runoff from areas of cropland

at a nonerosive rate.
Henderson County, Illinois 201

Table 17c

Irrigation is the controlled application of water to supplement rainfall and support

plant growth. The design and management of an irrigation system are affected by

depth to the water table, the need for drainage, flooding, available water capacity,

intake rate, permeability, erosion hazard, and slope. The construction of a system is

affected by large stones and depth to bedrock or a cemented pan. The performance of

a system is affected by the depth of the root zone, the amount of salts or sodium, and

soil reaction.

203

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 (fig. 13). “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, 2005) and the system adopted by the American Association of State

Highway and Transportation Officials (AASHTO, 2004).

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

Soil Properties
204 Soil Survey of

index number. Group index numbers range from 0 for the best subgrade material to 20

or higher for the poorest.

Rock fragments larger than 10 inches in diameter and 3 to 10 inches in diameter

are indicated as a percentage of the total soil on a dry-weight basis. The percentages

are estimates determined mainly by converting volume percentage in the field to

weight percentage.

Percentage (of soil particles) passing designated sieves is the percentage of the

soil fraction less than 3 inches in diameter based on an ovendry weight. The sieves,

numbers 4, 10, 40, and 200 (USA Standard Series), have openings of 4.76, 2.00,

0.420, and 0.074 millimeters, respectively. Estimates are based on laboratory tests of

soils sampled in the survey area and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits) indicate the plasticity

characteristics of a soil. The estimates are based on test data from the survey area or

from nearby areas and on field examination.

The estimates of particle-size distribution, liquid limit, and plasticity index are

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

Atterberg limits extend a marginal amount (1 or 2 percentage points) across

classification boundaries, the classification in the marginal zone is generally omitted in

the table.

Physical Properties

Table 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

Figure 13.—Percentages of clay, silt, and sand in the basic USDA soil textural classes.
Henderson County, Illinois 205

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 shrinkswell 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.
206 Soil Survey of

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

shrink-swell potential is low if the soil has a linear extensibility of less than 3 percent;

moderate if 3 to 6 percent; high if 6 to 9 percent; and very high if more than 9 percent.

If the linear extensibility is more than 3, shrinking and swelling can cause damage to

buildings, roads, and other structures and to plant roots. Special design commonly is

needed.

Organic matter is the plant and animal residue in the soil at various stages of

decomposition. In 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 (fig. 14).

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 fine-earth fraction, or the material

less than 2 millimeters in size.

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

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

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

Wind erodibility groups are made up of soils that have similar properties affecting

their susceptibility to wind erosion in cultivated areas. The soils assigned to group 1

are the most susceptible to wind erosion, and those assigned to group 8 are the least

susceptible. The groups are described in the “National Soil Survey Handbook” (USDA/

NRCS, National Soil Survey Handbook).

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.

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 cation-exchange capacity. The ability to retain cations reduces

the hazard of ground-water pollution.
Henderson County, Illinois 207

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

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

for soils that have pH of less than 5.5.

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

based on many field tests. For many soils, values have been verified by laboratory

analyses. Soil reaction is important in selecting crops and other plants, in evaluating

soil amendments for fertility and stabilization, and in determining the risk of corrosion.

Calcium carbonate equivalent is the percent of carbonates, by weight, in the fraction

of the soil less than 2 millimeters in size. The availability of plant nutrients is influenced

by the amount of carbonates in the soil. Incorporating nitrogen fertilizer into calcareous

soils helps to prevent nitrite accumulation and ammonium-N volatilization.

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

long-duration storms.

The four hydrologic soil groups are:

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

wet. These consist mainly of deep, well drained to excessively drained sands or

gravelly sands. These soils have a high rate of water transmission.

Figure 14.—Maintaining a cover crop in areas of the sandy Sparta soils helps to control erosion

and improves soil structure and the content of organic matter.
208 Soil Survey of

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.

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 of flooding 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).

Common is used when the occasional and frequent classes are grouped for certain

purposes.

The information is based on evidence in the soil profile, namely thin strata of gravel,

sand, silt, or clay deposited by floodwater; irregular decrease in organic matter content

with increasing depth; and little or no horizon development.

Also considered are local information about the extent and levels of flooding and the

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

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

surveys that delineate flood-prone areas at specific flood frequency levels.

Water table refers to a saturated zone in the soil. Table 21 indicates the depth to the

top (upper limit) and base (lower limit) of the saturated zone for the specified months
Henderson County, Illinois 209

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.

The table also shows 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.

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 has one or more physical,

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

air through the soil or that restrict roots or otherwise provide an unfavorable root

environment. Examples are bedrock, cemented layers, dense layers, and frozen

layers. Depth to top is the vertical distance from the soil surface to the upper boundary

of the restrictive layer.

Potential for frost action is the likelihood of upward or lateral expansion of the soil

caused by the formation of segregated ice lenses (frost heave) and the subsequent

collapse of the soil and loss of strength on thawing. Frost action occurs when moisture

moves into the freezing zone of the soil. Temperature, texture, density, permeability,

content of organic matter, and depth to the water table are the most important factors

considered in evaluating the potential for frost action. It is assumed that the soil is not

insulated by vegetation or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in winter are the most susceptible

to frost action. Well drained, very gravelly, or very sandy soils are the least susceptible.

Frost heave and low soil strength during thawing cause damage to pavements and

other rigid structures.

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

action that corrodes or weakens uncoated steel or concrete. The rate of corrosion of

uncoated steel is related to such factors as soil moisture, particle-size distribution,

acidity, and electrical conductivity of the soil. The rate of corrosion of concrete is based

mainly on the sulfate and sodium content, texture, moisture content, and acidity of the

soil. Special site examination and design may be needed if the combination of factors

results in a severe hazard of corrosion. The steel or concrete in installations that

intersect soil boundaries or soil layers is more susceptible to corrosion than the steel

or concrete in installations that are entirely within one kind of soil or within one soil

layer.

For uncoated steel, the risk of corrosion, expressed 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.

Many of the terms relating to landforms, geology, and geomorphology are defined in

more detail in the “National Soil Survey Handbook” (available in local offices of the

Natural Resources Conservation Service or on the Internet).

ABC soil. A soil having an A, a B, and a C horizon.

Ablation till. Loose, relatively permeable earthy material deposited during the

downwasting of nearly static glacial ice, either contained within or accumulated on

the surface of the glacier.

AC soil. A soil having only an A and a C horizon. Commonly, such soil formed in

recent alluvium or on steep, rocky slopes.

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

is considerably higher in carbon dioxide and lower in oxygen.

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

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

aggregates produced by tillage or logging.

Alluvial fan. A low, outspread mass of loose materials and/or rock material, commonly

with gentle slopes. It is shaped like an open fan or a segment of a cone. The

material was deposited by a stream at the place where it issues from a narrow

junction with the main stream. The fan is steepest near its apex, which points

upstream, and slopes gently and convexly outward (downstream) with a gradual

decrease in gradient.

Alluvium. Unconsolidated material, such as gravel, sand, silt, clay, and various

mixtures of these, deposited on land by running water.

Alpha,alpha-dipyridyl. A compound that when dissolved in ammonium acetate is

used to detect the presence of reduced iron (Fe II) in the soil. A positive reaction

implies reducing conditions and the likely presence of redoximorphic features.

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

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

redoximorphic features.

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

Aspect. The direction toward which a slope faces. Also called slope aspect.

Available water capacity (available moisture capacity). The capacity of soils to hold

water available for use by most plants. It is commonly defined as the difference

between the amount of soil water at field moisture capacity and the amount at

wilting point. It is commonly expressed as inches of water per inch of soil. The

capacity, in inches, in a 60-inch profile or to a limiting layer is expressed as:

Very low ..............................................................0 to 3

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

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

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

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

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

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

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.”

Contour stripcropping. Growing crops in strips that follow the contour. Strips of grass

or close-growing crops are alternated with strips of clean-tilled crops or summer

fallow.

erosion.

Cropping system. Growing crops according to a planned system of rotation and

management practices.

Cross-slope farming. Deliberately conducting farming operations on sloping farmland

in such a way that tillage is across the general slope.

Crown. The upper part of a tree or shrub, including the living branches and their

foliage.

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 stand reaches its maximum annual rate of growth is called the

culmination of the mean annual increment.

1.8 grams per cubic centimeter. Such a layer affects the ease of digging and can

affect filling and compacting.
Henderson County, Illinois 217

Depression. Any relatively sunken part of the earth’s surface; especially a low-lying

area surrounded by higher ground. A closed depression has no natural outlet for

surface drainage. An open depression has a natural outlet for surface drainage.

than 60 inches deep over bedrock; deep soils, 40 to 60 inches; moderately deep,

20 to 40 inches; shallow, 10 to 20 inches; and very shallow, less than 10 inches.

Diversion (or diversion terrace). A ridge of earth, generally a terrace, built to protect

downslope areas by diverting runoff from its natural course.

Divided-slope farming. A form of field stripcropping in which crops are grown in a

systematic arrangement of two strips, or bands, across the slope to reduce the

hazard of water erosion. One strip is in a close-growing crop that provides

protection from erosion, and the other strip is in a crop that provides less

protection from erosion. This practice is used where slopes are not long enough to

permit a full stripcropping pattern to be used.

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. A general term for a course or channel along which water moves in

draining an area. A term restricted to relatively small, linear depressions that at

some time move concentrated water and either do not have a defined channel or

have only a small defined channel.

Drift. A general term applied to all mineral material (clay, silt, sand, gravel, and

boulders) transported by a glacier and deposited directly by or from the ice or

transported by running water emanating from a glacier. Drift includes unstratified

eskers, kames, varves, and glaciofluvial sediments. The term is generally applied

to Pleistocene glacial deposits in areas that no longer contain glaciers.

Drumlin. A low, smooth, elongated oval hill, mound, or ridge of compact till that has a

core of bedrock or drift. It commonly has a blunt nose facing the direction from

which the ice approached and a gentler slope tapering in the other direction. The

longer axis is parallel to the general direction of glacier flow. Drumlins are products

of streamline (laminar) flow of glaciers, which molded the subglacial floor through

a combination of erosion and deposition.

plant material that is in the process of decomposition and includes everything from

the litter on the surface to underlying pure humus.

(generally sand), either barren and capable of movement from place to place or

covered and stabilized with vegetation but retaining its characteristic shape.

Earthy fill. See Mine spoil.

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.

frequently covered by floodwater from the present stream; any approximately

horizontal surface still actively modified by fluvial scour and/or deposition. May

occur individually or as a series of steps.

Fluvial. Of or pertaining to rivers or streams; produced by stream or river action.

matter and low or moderate in clay but high in silt or very fine sand. A fragipan

appears cemented and restricts roots. When dry, it is hard or very hard and has a

higher bulk density than the horizon or horizons above. When moist, it tends to

rupture suddenly under pressure rather than to deform slowly.

the unconsolidated parent material.

Geosol. A buried soil that formed on a landscape in the past with distinctive

table.

Gully. A small channel with steep sides caused by erosion and cut in unconsolidated

materials by concentrated but intermittent flow of water. 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 uses. Revegetation and erosion control are extremely

managed, residue from these crops can be used to control erosion until the next

crop in the rotation is established. These crops return large amounts of organic

matter to the soil.

Hill. A generic term for an elevated area of the land surface, rising as much as 1,000

feet above surrounding lowlands, commonly of limited summit area and having a

well defined outline. Slopes are generally more than 15 percent. The distinction

between a hill and a mountain is arbitrary and may depend on local usage.

Hillslope. A generic term for the steeper part of a hill between its summit and the

drainage line, valley flat, or depression floor at the base of a hill.

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.

L horizon.—A layer of organic and mineral limnic materials, including coprogenous

earth (sedimentary peat), diatomaceous earth, and marl.

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.
Henderson County, Illinois 221

B horizon.—The mineral horizon below an A horizon. The B horizon is in part a

layer of transition from the overlying A to the underlying C horizon. The B horizon

also has distinctive characteristics, such as (1) accumulation of clay, sesquioxides,

humus, or a combination of these; (2) prismatic or blocky structure; (3) redder or

browner colors than those in the A horizon; or (4) a combination of these.

C horizon.—The mineral horizon or layer, excluding indurated bedrock, that is little

affected by soil-forming processes and does not have the properties typical of the

overlying soil material. The material of a C horizon may be either like or unlike that

in which the solum formed. If the material is known to differ from that in the solum,

an Arabic numeral, commonly a 2, precedes the letter C.

Cr horizon.—Soft, consolidated bedrock beneath the soil.

R layer.—Consolidated bedrock beneath the soil. The bedrock commonly

underlies a C horizon, but it can be directly below an A or a B horizon.

Humus. The well decomposed, more or less stable part of the organic matter in

mineral soils.

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.

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

1.25 to 1.75 ....................................... moderately high

1.75 to 2.5 ............................................................. high

drainageways.

Interfluve (geomorphology). A geomorphic component of hills consisting of the

uppermost, comparatively level or gently sloping area of a hill; shoulders of

backwearing hillslopes can narrow the upland or can merge, resulting in a strongly

sand and gravel deposited by a subglacial stream as a fan or delta at the margin

of a melting glacier; by a supraglacial stream in a low place or hole on the surface

of the glacier; or as a ponded deposit on the surface or at the margin of stagnant

ice.

water.

Linear extensibility. Refers to the change in length of an unconfined clod as moisture

content is decreased from a moist to a dry state. Linear extensibility is used to

determine the shrink-swell potential of soils. 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. Volume change is influenced by the amount and

type of clay minerals in the soil. The volume change is the percent change for the

whole soil. If it is expressed as a fraction, the resulting value is COLE, coefficient

of linear extensibility.

Liquid limit. The moisture content at which the soil passes from a plastic to a liquid

state.

of the various horizons, and the thickness and arrangement of those horizons in

the soil profile.

Mottling, soil. Irregular spots of different colors that vary in number and size.

Descriptive terms are as follows: abundance—few, common, and many; size—fine,

pH value. A numerical designation of acidity and alkalinity in soil. (See Reaction, soil.)

Phase, soil. A subdivision of a soil series based on features that affect its use and

management, such as slope, stoniness, and flooding.

Piping (in tables). Formation of subsurface tunnels or pipelike cavities by water

moving through the soil.

Pitting (in tables). Pits caused by melting around ice. They form on the soil after plant

cover is removed.

Plastic limit. The moisture content at which a soil changes from semisolid to plastic.

Plasticity index. The numerical difference between the liquid limit and the plastic limit;

the range of moisture content within which the soil remains plastic.

Plinthite. The sesquioxide-rich, humus-poor, highly weathered mixture of clay with

quartz and other diluents. It commonly appears as red mottles, usually in platy,

polygonal, or reticulate patterns. Plinthite changes irreversibly to an ironstone

hardpan or to irregular aggregates on repeated wetting and drying, especially if it

is exposed also to heat from the sun. In a moist soil, plinthite can be cut with a

spade. It is a form of laterite.

Plowpan. A compacted layer formed in the soil directly below the plowed layer.

Ponding. Standing water on soils in closed depressions. Unless the soils are

artificially drained, the water can be removed only by percolation or

evapotranspiration.

Poorly graded. Refers to a coarse grained soil or soil material consisting mainly of

particles of nearly the same size. Because there is little difference in size of the

particles, density can be increased only slightly by compaction.

Pore linings. See Redoximorphic features.

Potential native plant community. See Climax plant community.

Potential rooting depth (effective rooting depth). Depth to which roots could

penetrate if the content of moisture in the soil were adequate. The soil has no

properties restricting the penetration of roots to this depth.

Prescribed burning. Deliberately burning an area for specific management purposes,

under the appropriate conditions of weather and soil moisture and at the proper

time of day.

Productivity, soil. The capability of a soil for producing a specified plant or sequence

of plants under specific management.

Profile, soil. A vertical section of the soil extending through all its horizons and into

the parent material.

Proper grazing use. Grazing at an intensity that maintains enough cover to protect

the soil and maintain or improve the quantity and quality of the desirable

vegetation. This practice increases the vigor and reproduction capacity of the key

plants and promotes the accumulation of litter and mulch necessary to conserve

soil and water.

Reaction, soil. A measure of acidity or alkalinity of a soil, expressed as pH values. A

soil that tests to pH 7.0 is described as precisely neutral in reaction because it is

Redoximorphic concentrations. See Redoximorphic features.

Redoximorphic depletions. See Redoximorphic features.

Redoximorphic features. Redoximorphic features are associated with wetness and

result from alternating periods of reduction and oxidation of iron and manganese

compounds in the soil. Reduction occurs during saturation with water, and

oxidation occurs when the soil is not saturated. Characteristic color patterns are

created by these processes. The reduced iron and manganese ions may be

removed from a soil if vertical or lateral fluxes of water occur, in which case there

is no iron or manganese precipitation in that soil. Wherever the iron and

manganese are oxidized and precipitated, they form either soft masses or hard

concretions or nodules. Movement of iron and manganese as a result of

redoximorphic processes in a soil may result in redoximorphic features that are

defined as follows:

1. Redoximorphic concentrations.—These are zones of apparent accumulation of

iron-manganese oxides, including:

A. Nodules and concretions, which are cemented bodies that can be removed

from the soil intact. Concretions are distinguished from nodules on the

basis of internal organization. A concretion typically has concentric layers

that are visible to the naked eye. Nodules do not have visible organized

internal structure; and

B. Masses, which are noncemented concentrations of substances within the

soil matrix; and

C. Pore linings, i.e., zones of accumulation along pores that may be either

coatings on pore surfaces or impregnations from the matrix adjacent to the

pores.

2. Redoximorphic depletions.—These are zones of low chroma (chromas less

than those in the matrix) where either iron-manganese oxides alone or both

iron-manganese oxides and clay have been stripped out, including:

A. Iron depletions, i.e., zones that contain low amounts of iron and

manganese oxides but have a clay content similar to that of the adjacent

matrix; and

B. Clay depletions, i.e., zones that contain low amounts of iron, manganese,

and clay (often referred to as silt coatings or skeletans).

3. Reduced matrix.—This is a soil matrix that has low chroma in situ but

undergoes a change in hue or chroma within 30 minutes after the soil material

has been exposed to air.

Reduced matrix. See Redoximorphic features.
Henderson County, Illinois 227

lacustrine, and pyroclastic deposits.

Relief. The relative difference in elevation between the upland summits and the

lowlands or valleys of a given region.

Residuum (residual soil material). Unconsolidated, weathered or partly weathered

mineral material that accumulated as bedrock disintegrated in place.

Rill. A very small, steep-sided channel resulting from erosion and cut in

unconsolidated materials by concentrated but intermittent flow of water. A rill

generally is not an obstacle to wheeled vehicles and is shallow enough to be

smoothed over by ordinary tillage.

Riser. The vertical or steep side slope (e.g., escarpment) of terraces, flood-plain

steps, or other stepped landforms; commonly a recurring part of a series of

natural, steplike landforms, such as successive stream terraces.

It is commonly on the uphill side of the road.

Rock fragments. Rock or mineral fragments having a diameter of 2 millimeters or

more; for example, pebbles, cobbles, stones, and boulders.

Root zone. The part of the soil that can be penetrated by plant roots.

Runoff. The precipitation discharged into stream channels from an area. The water

that flows off the surface of the land without sinking into the soil is called surface

runoff. Water that enters the soil before reaching surface streams is called groundwater runoff or seepage flow from ground water.

Saline soil. A soil containing soluble salts in an amount that impairs growth of plants.

A saline soil does not contain excess exchangeable sodium.

Sand. As a soil separate, individual rock or mineral fragments from 0.05 millimeter to

class, a soil that is 85 percent or more sand and not more than 10 percent clay.

Sandstone. Sedimentary rock containing dominantly sand-sized particles.

Sapric soil material (muck). The most highly decomposed of all organic soil material.

Muck has the least amount of plant fiber, the highest bulk density, and the lowest

water content at saturation of all organic soil material.

Saturation. Wetness characterized by zero or positive pressure of the soil water.

Under conditions of saturation, the water will flow from the soil matrix into an

unlined auger hole.

Scarification. The act of abrading, scratching, loosening, crushing, or modifying the

surface to increase water absorption or to provide a more tillable soil.

Second bottom. The first terrace above the normal flood plain (or first bottom) of a

river.

Sedimentary rock. A consolidated deposit of clastic particles, chemical precipitates,

or organic remains accumulated at or near the surface of the earth under normal

low temperature and pressure conditions. Sedimentary rocks include consolidated

equivalents of alluvium, colluvium, drift, and eolian, lacustrine, and marine

deposits. Examples are sandstone, siltstone, mudstone, claystone, shale,

conglomerate, limestone, dolomite, and coal.

Sequum. A sequence consisting of an illuvial horizon and the overlying eluvial horizon.

(See Eluviation.)

silty clay loam and that has a tendency to split into thin layers.
228 Soil Survey of

Sheet erosion. The removal of a fairly uniform layer of soil material from the land

surface by the action of rainfall and surface runoff.

Shoulder. The convex, erosional surface near the top of a hillslope. A shoulder is a

transition from summit to backslope.

Shrink-swell (in tables). The shrinking of soil when dry and the swelling when wet.

Shrinking and swelling can damage roads, dams, building foundations, and other

structures. It can also damage plant roots.

Side slope (geomorphology). A geomorphic component of hills consisting of a laterally

planar area of a hillside. The overland waterflow is predominantly parallel. Side

slopes are dominantly colluvium and slope-wash sediments.

Silica. A combination of silicon and oxygen. The mineral form is called quartz.

Silica-sesquioxide ratio. The ratio of the number of molecules of silica to the number

of molecules of alumina and iron oxide. The more highly weathered soils or their

clay fractions in warm-temperate, humid regions, and especially those in the

tropics, generally have a low ratio.

Silt. As a soil separate, individual mineral particles that range in diameter from the

upper limit of clay (0.002 millimeter) to the lower limit of very fine sand (0.05

millimeter). As a soil textural class, soil that is 80 percent or more silt and less than

12 percent clay.

Siltstone. An indurated silt having the texture and composition of shale but lacking its

fine lamination or fissility; a massive mudstone in which silt predominates over

clay.

Similar soils. Soils that share limits of diagnostic criteria, behave and perform in a

similar manner, and have similar conservation needs or management

requirements for the major land uses in the survey area.

Site index. A designation of the quality of a forest site based on the height of the

dominant stand at an arbitrarily chosen age. For example, if the average height

attained by dominant and codominant trees in a fully stocked stand at the age of

50 years is 75 feet, the site index is 75.

Slickensides (pedogenic). Grooved, striated, and/or glossy (shiny) slip faces on

structural peds, such as wedges; produced by shrink-swell processes, most

commonly in soils that have a high content of expansive clays.

Slope. The inclination of the land surface from the horizontal. Percentage of slope is

the vertical distance divided by horizontal distance, then multiplied by 100. Thus, a

slope of 20 percent is a drop of 20 feet in 100 feet of horizontal distance.

Slope alluvium. Sediment gradually transported down the slopes of mountains or hills

primarily by nonchannel alluvial processes (i.e., slope-wash processes) and

characterized by particle sorting. Lateral particle sorting is evident on long slopes.

In a profile sequence, sediments may be distinguished by differences in size and/

or specific gravity of rock fragments and may be separated by stone lines.

Burnished peds and sorting of rounded or subrounded pebbles or cobbles

distinguish these materials from unsorted colluvial deposits.

Sloughed till. Water-saturated till that has flowed slowly downhill from its original

place of deposit by glacial ice. It may rest on other till, on outwash, or on a

glaciolacustrine deposit.

Slow refill (in tables). The slow filling of ponds, resulting from restricted permeability in

the soil.

Soft bedrock. Bedrock that can be excavated with trenching machines, backhoes,

small rippers, and other equipment commonly used in construction.

Soil. A natural, three-dimensional body at the earth’s surface. It is capable of

supporting plants and has properties resulting from the integrated effect of climate

and living matter acting on earthy parent material, as conditioned by relief and by

the passage of time.
Henderson County, Illinois 229

Solum. The upper part of a soil profile, above the C horizon, in which the processes of

soil formation are active. The solum in soil consists of the A, E, and B horizons.

Generally, the characteristics of the material in these horizons are unlike those of

the material below the solum. The living roots and plant and animal activities are

largely confined to the solum.

Stone line. In a vertical cross section, a line formed by scattered fragments or a

discrete layer of angular and subangular rock fragments (commonly a gravel- or

cobble-sized lag concentration) that formerly was draped across a topographic

surface and was later buried by additional sediments. A stone line generally caps

material that was subject to weathering, soil formation, and erosion before burial.

Many stone lines seem to be buried erosion pavements, originally formed by sheet

and rill erosion across the land surface.

Stones. Rock fragments 10 to 24 inches (25 to 60 centimeters) in diameter if rounded

or 15 to 24 inches (38 to 60 centimeters) in length if flat.

Stony. Refers to a soil containing stones in numbers that interfere with or prevent

tillage.

Strath terrace. A type of stream terrace; formed as an erosional surface cut on

bedrock and thinly mantled with stream deposits (alluvium).

Stream terrace. One of a series of platforms in a stream valley, flanking and more or

less parallel to the stream channel, originally formed near the level of the stream;

represents the remnants of an abandoned flood plain, stream bed, or valley floor

produced during a former state of fluvial erosion or deposition.

Stripcropping. Growing crops in a systematic arrangement of strips or bands that

provide vegetative barriers to wind erosion and water erosion.

Structure, soil. The arrangement of primary soil particles into compound particles or

aggregates. The principal forms of soil structure are—platy (laminated), prismatic

(vertical axis of aggregates longer than horizontal), columnar (prisms with rounded

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

single grain (each grain by itself, as in dune sand) or massive (the particles

adhering without any regular cleavage, as in many hardpans).

Stubble mulch. Stubble or other crop residue left on the soil or partly worked into the

soil. It protects the soil from wind erosion and water erosion after harvest, during

preparation of a seedbed for the next crop, and during the early growing period of

the new crop.

Subsoil. Technically, the B horizon; roughly, the part of the solum below plow depth.

Subsoiling. Tilling a soil below normal plow depth, ordinarily to shatter a hardpan or

claypan.

Substratum. The part of the soil below the solum.

Subsurface layer. Any surface soil horizon (A, E, AB, or EB) below the surface layer.

Summer fallow. The tillage of uncropped land during the summer to control weeds

and allow storage of moisture in the soil for the growth of a later crop. A practice

common in semiarid regions, where annual precipitation is not enough to produce
230 Soil Survey of

a crop every year. Summer fallow is frequently practiced before planting winter

grain.

Summit. The topographically highest position of a hillslope. It has a nearly level

(planar or only slightly convex) surface.

Surface layer. The soil ordinarily moved in tillage, or its equivalent in uncultivated soil,

ranging in depth from 4 to 10 inches (10 to 25 centimeters). Frequently designated

as the “plow layer,” or the “Ap horizon.”

Surface soil. The A, E, AB, and EB horizons, considered collectively. It includes all

subdivisions of these horizons.

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 to

be of consequence in interpreting their use and behavior. Soils are recognized as

taxadjuncts only when one or more of their characteristics are slightly outside the

range defined for the family of the series for which the soils are named.

Terminal moraine. An end moraine that marks the farthest advance of a glacier. It

typically has the form of a massive arcuate or concentric ridge, or complex of

ridges, and is underlain by till and other types of drift.

Terrace (conservation). An embankment, or ridge, constructed across sloping soils on

the contour or at a slight angle to the contour. The terrace intercepts surface runoff

so that water soaks into the soil or flows slowly to a prepared outlet. A terrace in a

field generally is built so that the field can be farmed. A terrace intended mainly for

drainage has a deep channel that is maintained in permanent sod.

Terrace (geomorphology). A steplike surface, bordering a valley floor or shoreline, that

represents the former position of a flood plain, lake, or seashore. The term is

usually applied both to the relatively flat summit surface (tread) that was cut or

built by stream or wave action and to the steeper descending slope (scarp or riser)

that has graded to a lower base level of erosion.

Terracettes. Small, irregular steplike forms on steep hillslopes, especially in pasture,

formed by creep or erosion of surficial materials that may be induced or enhanced

by trampling of livestock, such as sheep or cattle.

Texture, soil. The relative proportions of sand, silt, and clay particles in a mass of soil.

The basic textural classes, in order of increasing proportion of fine particles, are

sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam,

silty clay loam, sandy clay, silty clay, and clay. The sand, loamy sand, and sandy

loam classes may be further divided by specifying “coarse,” “fine,” or “very fine.”

Thin layer (in tables). Otherwise suitable soil material that is too thin for the specified

use.

Till. Dominantly unsorted and nonstratified drift, generally unconsolidated and

deposited directly by a glacier without subsequent reworking by meltwater, and

consisting of a heterogeneous mixture of clay, silt, sand, gravel, stones, and

boulders; rock fragments of various lithologies are embedded within a finer matrix

that can range from clay to sandy loam.

Till plain. An extensive area of level to gently undulating soils underlain predominantly

by till and bounded at the distal end by subordinate recessional or end moraines.

Tilth, soil. The physical condition of the soil as related to tillage, seedbed preparation,

seedling emergence, and root penetration.

Toeslope. The gently inclined surface at the base of a hillslope. Toeslopes in profile

are commonly gentle and linear and are constructional surfaces forming the lower

part of a hillslope continuum that grades to valley or closed-depression floors.

Topsoil. The upper part of the soil, which is the most favorable material for plant

growth. It is ordinarily rich in organic matter and is used to topdress roadbanks,

lawns, and land affected by mining.
Henderson County, Illinois 231

Trace elements. Chemical elements, for example, zinc, cobalt, manganese, copper,

and iron, in soils in extremely small amounts. They are essential to plant growth.

Tread. The flat to gently sloping, topmost, laterally extensive slope of terraces, floodplain steps, or other stepped landforms; commonly a recurring part of a series of

natural steplike landforms, such as successive stream terraces.

Tuff. A generic term for any consolidated or cemented deposit that is 50 percent or

more volcanic ash.

Upland. An informal, general term for the higher ground of a region, in contrast with a

low-lying adjacent area, such as a valley or plain, or for land at a higher elevation

than the flood plain or low stream terrace; land above the footslope zone of the

hillslope continuum.

Valley fill. In glaciated regions, material deposited in stream valleys by glacial

meltwater. In nonglaciated regions, alluvium deposited by heavily loaded streams.

Variegation. Refers to patterns of contrasting colors assumed to be inherited from the

parent material rather than to be the result of poor drainage.

Varve. A sedimentary layer or a lamina or sequence of laminae deposited in a body of

still water within a year. Specifically, a thin pair of graded glaciolacustrine layers

seasonally deposited, usually by meltwater streams, in a glacial lake or other body

of still water in front of a glacier.

Water bars. Smooth, shallow ditches or depressional areas that are excavated at an

angle across a sloping road. They are used to reduce the downward velocity of

water and divert it off and away from the road surface. Water bars can easily be

driven over if constructed properly.

Weathering. All physical disintegration, chemical decomposition, and biologically

induced changes in rocks or other deposits at or near the earth’s surface by

atmospheric or biologic agents or by circulating surface waters but involving

essentially no transport of the altered material.

Well graded. Refers to soil material consisting of coarse grained particles that are well

distributed over a wide range in size or diameter. Such soil normally can be easily

increased in density and bearing properties by compaction. Contrasts with poorly

graded soil.

Wilting point (or permanent wilting point). The moisture content of soil, on an

ovendry basis, at which a plant (specifically a sunflower) wilts so much that it does

not recover when placed in a humid, dark chamber.

Windthrow. The uprooting and tipping over of trees by the wind.

 larger the value, the greater the limitation. See text for further explanation of ratings in

 this table)

Table 16a.--Construction Materials

(The information in this table indicates the

 dominant soil condition but does not

 eliminate the need for onsite

 investigation. The ratings given for the

 thickest layer are for the thickest layer

 above and excluding the bottom layer. The

 numbers in the value columns range from

 0.00 to 0.99. The greater the value, the

 greater the likelihood that the bottom

 layer or thickest layer of the soil is a

 source of sand. See text for further

 explanation of ratings in this table)
