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

Lee County Soil and Water Conservation District.

Major fieldwork for this soil survey was completed in 2003. Soil names and

descriptions were approved in 2003. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 2003. 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.

LEE COUNTY is in north-central Illinois (fig. 1). It has an area of 466,500 acres, or 728

square miles. It is bounded by Ogle County on the north, De Kalb County on the east,

Bureau County and part of La Salle County on the south, and Whiteside County on the

west.

This survey area is a subset of Major Land Resource Areas (MLRAs) 108A and

108B, the Illinois and Iowa Deep Loess and Drift (USDA, 1981).

Lee County was established in 1839. In 2000, the population was 36,062 (U.S.

Department of Commerce, 2004). Dixon, the county seat and largest town, has a

population of 15,941 (U.S. Department of Commerce, 2004).

This soil survey updates the survey of Lee County published in 1985 (Zwicker,

1985). This updated survey provides additional soils information.

General Nature of the Survey Area

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

transportation facilities and industry; farming; relief, physiography, and drainage; and

climate.

Transportation Facilities and Industry

Lee County has a well developed system of transportation. Interstate 39, U.S.

Highway 52, and State Highway 251 cross the county from north to south. Interstate

Highway 88, U.S. Highway 30, and State Highway 38 cross the county from east to

west. The main secondary roads are blacktopped. Most rural areas are accessible by

all-weather roads. Railroads furnish freight service to the county.

county. A wind energy farm has recently been completed near Mendota with a

capacity to generate 50.4 megawatts of electricity (fig. 2). A number of pits provide

crushed rock for roads and sand and gravel for building material.

Farming

Farming has been a major enterprise in Lee County since the area was settled. In

2002, the county had 842 operating farms (USDA, 2003). The average farm size was

about 462 acres. Corn, soybeans, alfalfa hay, and wheat are the main crops. In 2002,

210,568 acres was used for corn; 141,818 acres was used for soybeans; 4,380 acres

was used for alfalfa hay; and 1,157 acres was used for wheat (USDA, 2003).

Hogs and cattle are the main livestock. In 2002, the total number of swine was

55,414 and the total number of cattle was 15,173 (USDA, 2003).

Relief, Physiography, and Drainage

The landscape of Lee County consists of five major landforms: uplands, outwash

plains, lake plains, stream terraces, and flood plains. These landforms are the products

of continental glaciation and more recent stream erosion. The deposition of till and

postglacial stream erosion have modified the original bedrock topography to create the

present rolling terrain. The outwash plain and lake plain consist of materials deposited

by meltwater from the receding glacier. The flood plains and stream terraces are the

result of the ongoing process of stream erosion. The lowest point in the county occurs

along the Rock River where it exits the western side of the county at an elevation of

about 640 feet above sea level. The highest point occurs at an elevation of about 985

feet above sea level on the glacial moraine about 2.6 miles northeast of the town of

Figure 2.—Wind turbines in a farm field.
4 Soil Survey of

Paw Paw, near the Lee-De Kalb county line (fig. 3). The thickest glacial deposits in the

state occur in this same area, where the moraine crosses a deep preglacial valley

known as the Paw Paw Bedrock Valley. Glacial deposits over this valley are nearly 600

feet thick (Piskin and Bergstrom, 1975).

Most of the county is uplands that are divided by major stream channels. The

uplands generally consist of 5 or more feet of loess over till. Till is exposed in many

places on the steeper slopes. Some limestone or sandstone bedrock is exposed along

the steeper slopes immediately east and west of Dixon. The prominent ridges on the

east side of the county are part of the Bloomington Morainic System, which runs from

northeast to southwest across the county. It consists of a series of undulating ridges

and closed depressions, resulting from repeated cycles of advance and retreat during

the overall recession of glacial ice from west to east in Illinois. Relief in general ranges

from about 800 feet at the foot of the moraine to about 985 feet at the highest point on

the moraine. Local relief on the moraine ranges from about 10 to 90 feet.

At the foot of the prominent Bloomington Morainic System, a broad outwash plain

lies roughly between Steward and Ashton and then south along the foot of the moraine

below Amboy. About 3 to 4 feet of loess overlies the sandy and gravelly outwash in the

northern and central parts of the county. Beginning about 2 miles south of Route 30,

however, stabilized sand dunes have formed on the outwash deposits and on the front

slope of the Bloomington Moraine. Likewise, on the western side of the county, from

Nelson south along the county line, outwash deposits occur in an area 1 to 4 miles

wide within the county and extend west toward Rock Falls. Sand dunes are common

on the outwash plain in this area. The outwash formations were created when

meltwater distributed sandy and loamy material in front of the Bloomington Moraine as

the ice melted back. These deposits were subsequently capped with a thin layer of

loess in the northern part of the county. In the southern and western parts of the

county, they were reworked by the wind into numerous sand dunes. Elevation ranges

from about 650 to 800 feet above sea level. Local relief is generally very low, but near

the sand dunes it may be 10 to 70 feet.

A major lake plain occurs mainly north of Route 30 at the upper end of the Green

River at an elevation of about 760 feet above sea level. About 4 feet of silty calcareous

deposits overlie sandy outwash deposits. The lakebed formed on the outwash plain in

front of the Bloomington Moraine when glacial meltwater became trapped behind the

bedrock high near Amboy (Lineback and others, 1979). In the early 1800s, this area

was referred to as “Inlet Swamp” because of a bedrock ledge near the center of

section 9, Lee Center Township, that was a natural barrier for drainage for over 30,000

acres of land above it. The Inlet Swamp Drainage District was formed in 1887.

Drainage was completed in 1901 after a channel through the bedrock was deepened

to 5 feet and widened to 30 feet (Bardwell, 1901).

The stream terraces are most extensive in the northern part of the county along the

Rock River flood plain. These areas are remnants of an old flood plain. Recent

downcutting and channelization along the current flood plain have left the stream

terrace positions at an elevation that is no longer subject to flooding. The terraces are

commonly separated from the active flood plain by a short, steep slope called a

terrace escarpment. Elevation ranges from about 610 to 730 feet above sea level.

Local relief is generally very low, commonly less than 10 feet.

The major flood plains in the county are along the Rock River and the Green River

and their adjoining tributaries. Elevation on the flood plains ranges from a low of about

630 feet above sea level along the Rock River where it exits Lee County to about 780

feet in the upper reaches of the Green River Lowlands.

Lee County is within the Rock River and Green River drainage basins, which

eventually drain into the Mississippi River further west. The Rock River drains the

northern part of the county. Major tributaries of the Rock River are Franklin, Steward,

Willow, Beach, Sugar, Threemile, and Fivemile Creeks and Main and Winnebago

Ditches. All of these, except Franklin and Willow Creeks, join the Rock River outside of

Lee County. The Green River drains the central part of the county. Major tributaries to

the Green River are Willow Creek and Red Oak Ditch. The southern and southeastern

parts of the county are drained by tributaries to Big Bureau Creek, which is part of the

regional drainage into the Illinois River south of Lee County.

Climate

Lee County is cold in winter. In summer it generally is hot but has occasional cool

spells. Precipitation falls as snow during frequent snowstorms in winter and chiefly as

rain showers, which often are heavy, during the warmer periods, when warm moist air

moves in from the south. The amount of annual rainfall usually is adequate for corn,

soybeans, and small grain.

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

at Paw Paw 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 22 degrees F and the average daily

minimum temperature is 14 degrees. The lowest temperature on record, which

occurred at Paw Paw on February 3, 1996, is -33 degrees. In summer, the average

temperature is 70 degrees and the average daily maximum temperature is about 81

degrees. The highest recorded temperature, which occurred at Paw Paw on June 26,

1988, is 101 degrees.
6 Soil Survey of

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 36.85 inches. Of this total, 24.14 inches, or about 66

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 12.26 inches. The heaviest 1-day rainfall on record is 6.92 inches on June

24, 1994. Thunderstorms occur on about 50 days each year.

The average seasonal snowfall is 30.6 inches. The heaviest 1-day snowfall on

record is 14 inches on January 27, 1967. The greatest snow depth at any one time on

record is 29 inches on January 19, 1979. On average, 48 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 Area 108

(fig. 1). Major land resource areas (MLRAs) are geographically associated land

resource units that share a common land use, elevation, topography, climate, water,

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

are based on the occurrence of each soil throughout the MLRA. In some cases a soil

may be referred to that was not mapped in the Lee County survey but that is

representative of the MLRA.

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; the kinds of crops and native plants; and the kinds of bedrock.

They dug many holes to study the soil profile, which is the sequence of natural layers,

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

unconsolidated material in which the soil formed. The unconsolidated material is

devoid of roots and other living organisms and has not been changed by other

biological activity.

The soils and miscellaneous areas in the survey area are in an orderly pattern that

is related to the geology, landforms, relief, climate, and natural vegetation of the area.

Each kind of soil and miscellaneous area is associated with a particular kind or

segment of the landscape. By observing the soils and miscellaneous areas in the

survey area and relating their position to specific segments of the landscape, soil

scientists develop a concept, or model, of how the soils were formed. Thus, during

mapping, this model enables the soil scientists to predict with a considerable degree of

accuracy the kind of soil or miscellaneous area at a specific location on the landscape.

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

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

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

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

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

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

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

noted soil color, texture, size and shape of soil aggregates, kind and amount of rock

fragments, distribution of plant roots, soil reaction, and other features that enable them

to identify soils. After describing the soils in the survey area and determining their

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

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

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

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

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

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

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

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

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

research.

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

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

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

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

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

in different uses and under different levels of management. Interpretations are

modified as necessary to fit local conditions, and some new interpretations are

developed to meet local needs. Data are assembled from other sources, such as

research information, production records, and field experience of specialists. For

example, data on crop yields under defined levels of management are assembled from

farm records and from field or plot experiments on the same kinds of soil.

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

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

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

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

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

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

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

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

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

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

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

fully agree with those of the soils in adjacent 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

A soil is a three-dimensional natural body consisting of mineral and organic material

that can support plants. Soil-forming processes act on deposited or accumulated

geologic material. The nature of any soil at a given site is the result of the interaction of

the major factors of soil formation and their influence on the processes of soil

formation.

Factors of Soil Formation

The major factors of soil formation are the physical and mineralogical composition

of the parent material; living organisms, both on and in the soil; the climate in which

the soil formed; the topography, or relief; and the length of time that the forces of soil

formation have acted on the parent 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

Dr. John P. Kempton, geologist (retired), Illinois State Geological Survey, and Dr. Leon Follmer,

geologist, Illinois State Geological Survey, helped prepare this section.

The nature and distribution of the surficial materials in Lee County provide a basis

for understanding the soils. The soils in the county formed in loess, till, outwash

deposits, eolian deposits, lacustrine deposits, alluvium, organic material, paleosols,

and material weathered from limestone and sandstone.

Loess, or silty wind-deposited material, is the most extensive parent material in the

county. It blankets many of the other parent materials. The major source of the loess

was the Mississippi River Valley, about 30 miles west of Lee County.

The loess is referred to as Peoria Silt west of the Green River, where it reaches a

maximum thickness of about 16 feet and overlies older silty deposits and Illinoian

glacial deposits. Where it overlies Wisconsinan till east of the Green River, it was

formerly called Richland Loess. Now it is included with the Peoria Silt, which is a

geologic mapping unit that is mostly loess and includes other kinds of silty deposits

Formation and Classification of

the Soils
10 Soil Survey of

(Hansel and Johnson, 1996). The moderately well drained Osco and somewhat poorly

drained Muscatune soils formed in loess that is more than 5 feet thick.

Till, which is commonly called glacial till, is unsorted, nonstratified, pulverized rock

and sediments consisting of clay, silt, sand, pebbles, and boulders transported and

deposited by glacial ice. In Lee County the till typically is clay, clay loam, loam, or

sandy loam and is calcareous. A recent map of the Quaternary deposits of Illinois

shows six tills at or near the surface in Lee County (Lineback and others, 1979). The

area was glaciated many times, and many varieties of till were produced. Most of the

older tills are buried (Willman and Frye, 1970), but four come to the surface in Lee

County underneath the cover of soil and loess. Old soils, called paleosols, developed

in all of the older deposits at one time; in general, these paleosols are weathered

zones. However, ancient erosion removed the paleosols at many locations. The

landscape to a large extent reflects the distribution of the tills. The older landscapes,

on the older tills, tend to be flat, and the younger landscapes are more rolling. All tills in

the weathered zone are leached; have typical altered colors of light gray, yellow,

brown, or red; and become calcareous and dark gray with depth.

The oldest of the tills at or near the surface is the Sterling Till. It is within 5 feet of

the surface on side slopes where the loess is thin. It is gray clay loam to clay till,

mainly in South Dixon and Palmyra Townships. The moderately well drained

Assumption soils formed in 20 to 40 inches of loess and in a paleosol that formed in

the Sterling Till.

Lee Center Till covers some areas in the west-central part of the county. It is a

yellowish brown loam to silty clay till. The moderately well drained Prairieville and

somewhat poorly drained Nachusa soils formed in a thin layer of silty and loamy eolian

material and in a paleosol that formed in till. In earlier work a paleosol in the Lee

Center Till was not observed, and this served as the basis for distinguishing Lee

Center Till from Sterling Till; however, both are now considered equivalent. Both

become clayey with depth and may range up to 20 feet thick or more. In the northcentral part of the county, the Esmond Till occurs. It also is equivalent to the Lee

Center and Sterling Tills in age, but it tends to be more clayey near the surface and

does not have a paleosol in most places. Erosion before the last glaciation removed

most of the paleosol zone from the old tills across most of Lee County before the area

was buried by Wisconsinan loesses. As a result, the parent material for modern soils is

highly variable from place to place.

Argyle Till is on side slopes along Sugar and Franklin Creeks and their tributaries. It

is a brownish yellow sandy loam till and may have a paleosol. The well drained Kidder

soils formed in a thin layer of loess and in the underlying sandy loam till. The well

drained Griswold soils formed in sandy loam till. In rare places a reddish clayey

paleosol occurs below the loess.

Tiskilwa Till is the thickest and one of the youngest tills in the county. It forms the

prominent Bloomington Morainal System, a range of hills that swings in an arcuate

pattern from the northeast corner of the county to the southwest corner. It is a

yellowish brown to reddish gray loam till and is commonly 100 to 150 feet thick

beneath the higher parts of the moraine. A younger till occurs southeast of and roughly

parallel to the Bloomington Morainal System. It was formerly called Malden Till and is

now correlated with the Batestown Till (Hansel and Johnson, 1996). This till contains a

higher proportion of fresh minerals but overall is similar to the Tiskilwa Till. As parent

materials, these tills are similar enough that the same soils formed in both tills. The

moderately well drained Saybrook and well drained Wyanet soils formed in these tills.

Both soils have loess in the upper part of the profile.

Outwash material is deposited by running water from melting glaciers. It consists of

layers of different particle sizes. The sorting of individual layers of material is related to

stream velocity at the time of deposition. The coarser textured layers are related to
Lee County, Illinois 11

high stream velocities, and the finer textured layers are related to low stream

velocities. Outwash is extensive in the county. A large area of sand and gravel is in

front of the Bloomington Moraine near Steward. The well drained Waupecan,

somewhat poorly drained Grundelein, and poorly drained Dunham soils formed in

loess and in the underlying stratified outwash.

Sand dunes formed when westerly winds reworked sandy outwash deposits after

glacial meltwater receded. These eolian deposits are most extensive in the

southwestern part of the county. Most are on the flood plain in the Green River

Lowlands. Some are in the uplands east of the flood plain. Also, numerous dunes are

adjacent to the Rock River. The excessively drained Coloma and Sparta soils formed

in sandy material reworked by wind.

Lacustrine material was deposited by glacial meltwater. After the coarser particles

were deposited as outwash by moving water, the finer particles of silt and clay were

deposited in lakes or other still water. The poorly drained Milford soils formed in clayey

and silty lacustrine sediments.

Alluvial material was recently deposited by floodwater from streams. The velocity of

the floodwater determines the texture of the material deposited. An extensive area of

alluvium occurs in the southwestern part of the county along the Green River. Before

this stream was channelized, it meandered across the flood plain and deposited

alluvium of various sand content, depending upon the velocity of any given flood. At

times, the stream was very sluggish and deposited alluvium with small amounts of

sand. During peak storm events the stream ran much faster and deposited alluvium

with a much higher sand content. Cohoctah soils formed in alluvium with a higher sand

content than that of the Ambraw soils in the same area. Ambraw soils formed in

alluvium deposited during periods of relatively low stream velocities.

Organic material is made up of partially decomposed plant remains. When the

glaciers receded, water was left standing in depressions on outwash plains and till

plains. Water-tolerant plants eventually filled in these areas through the process of

growth and decay, and large areas of muck were formed. The very poorly drained

Adrian and Houghton soils formed in organic material.

Bedrock occurs mostly in the northern part of the county near Dixon and Ashton. It

is mainly Ordovician in age and generally is Galena-Platteville dolomitic limestone and

Glenwood and St. Peter sandstone (Willman and others, 1975). The well drained

Whalan soils formed in 20 to 40 inches of loamy material and clayey limestone

residuum. The somewhat excessively drained Eleva soils formed in 20 to 40 inches of

material weathered from sandstone bedrock.

Living Organisms

Plants are the principal living organisms affecting the formation of soils in Lee

County. Bacteria, fungi, and earthworms, however, also have affected soil formation.

The chief contribution of plant and animal life is the addition of organic matter and

nitrogen to the soil. The kind of organic material on and in the soil depends on the kind

of plants that grew on the soil. The remains of these plants accumulate in the surface

layer, decay, and eventually become organic matter. The roots of the plants provide

channels for the downward movement of water through the soil and add organic matter

as they decay. Bacteria in the soil help to break down the organic matter and thus help

to provide plant nutrients.

The native vegetation in the county was trees and prairie grasses. The sloping soils

formed mainly under forests of oak, hickory, and similar trees. The nearly level soils

formed under prairie grasses. They have a darker and thicker surface layer than that of

the soils that formed under forest vegetation. Also, they have a higher content of

organic matter. Fayette soils are an example of soils that formed under forest

vegetation. Muscatune soils are an example of soils that formed under prairie

vegetation.
12 Soil Survey of

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 Lee 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 Lee County, the slopes

dominantly range from 0 to 35 percent. Natural soil drainage ranges from excessively

drained on sandy ridgetops to very poorly drained in depressions.

Topography influences the formation of soils by affecting runoff and drainage.

Drainage in turn, through its effect on aeration of the soils, determines the color of the

soil. Runoff is most rapid on the steeper slopes, but in low areas, water is temporarily

ponded. Water and air move freely through well drained soils but slowly through poorly

drained soils. In well aerated soils, the iron compounds that give most soils their color

are brightly colored. In poorly aerated soils, the colors are gleyed and mottled. Fayette

soils are an example of well drained, well aerated soils. Sable soils are an example of

poorly drained, poorly aerated soils.

Time

Time, usually several thousand years, is needed for the agents of soil formation to

result in the development of distinct horizons. Differences in the length of time that the

parent materials have been in place are commonly reflected in the degree of profile

development. Over a given period, however, some soils form rapidly whereas others

form slowly.

In general, the more rapidly permeable soils having easily weatherable minerals

and a low content of calcium carbonate form more rapidly than slowly permeable soils

having a high content of calcium carbonate. Soils form more rapidly under forest

vegetation than under prairie vegetation because the water penetrating the surface is

more acid under forest vegetation and is more effective in leaching soluble bases. Soil

formation in areas of strongly sloping topography is slower than in the less sloping

areas because less water infiltrates the soil and the resulting runoff increases natural

erosion of the surface layer. A soil that forms in nearly level areas accumulates water

from adjacent slopes. The accumulation of water results in more rapid leaching of the

more soluble compounds and thus in more rapid soil formation.

The soils in Lee County generally have moderately expressed horizons, but they

range from young to mature. Coarse textured soils, such as Coloma and Sparta soils,

consist mostly of slowly weatherable quartz minerals, which do not readily form soil

horizons even though they are readily leached of calcium carbonates and tend to

become acid. These soils remain youthful over time. Soils that formed in recent alluvial

sediments, such as Lawson and Otter soils, also remain youthful because of the

frequently deposited alluvium. Soils intermediate in maturity, such as Fayette and

Osco soils, are on relatively stable landscapes where deposition is negligible. These

soils develop horizons from permeable, medium textured loess over a relatively short

period.

Denny soils are an example of mature soils that have distinct horizons. They have

leached subsurface horizons and contain more clay in the subsoil than the Osco soils.
Lee County, Illinois 13

They formed in depressions, which collect runoff from surrounding slopes. The

infiltrating water leaches soluble minerals from the surface layer to the subsoil at an

accelerated rate.

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 county. 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. The adjective Typic identifies the subgroup that typifies the great group. An

example is Typic Endoaquolls.

FAMILY. Families are established within a subgroup on the basis of physical and

chemical properties and other characteristics that affect management. Generally, the

properties are those of horizons below plow depth where there is much biological

activity. Among the properties and characteristics considered are particle-size class,

mineral content, cation-exchange capacity, temperature regime, thickness of the root

zone, consistence, moisture equivalent, slope, and permanent cracks. A family name

consists of the name of a subgroup preceded by terms that indicate soil properties. An

example is fine-silty, mixed, superactive, mesic Typic Endoaquolls.

SERIES. The series consists of soils that have similar horizons in their profile. The

horizons are similar in color, texture, structure, reaction, consistence, mineral and

chemical composition, and arrangement in the profile. The texture of the surface layer

or of the substratum can differ within a series. The Drummer series is a soil series in

this survey area.

15

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
16 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, Saybrook

silty clay loam, 5 to 10 percent slopes, eroded, is a phase of the Saybrook series.

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

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

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

(see Contents) give properties of the soils and the limitations, capabilities, and

potentials for many uses. The Glossary defines many of the terms used in describing

the soils or miscellaneous areas.

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

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

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

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

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

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

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

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

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

crops and pasture; as forestland; as sites for buildings, sanitary facilities, highways and

other transportation systems, and parks and other recreational facilities; and as wildlife

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

land uses and to help prevent construction failures caused by unfavorable soil

properties.

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

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

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

natural soil.

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

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

layers can cause difficulty in excavation.

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

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

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

Interpretive Ratings

The interpretive tables in this survey rate the soils in the survey area for various

uses. Many of the tables identify the limitations that affect specified uses and indicate

the severity of those limitations. The ratings in these tables are both verbal and

numerical.

Rating Class Terms

Rating classes are expressed in the tables in terms that indicate the extent to which

the soils are limited by all of the soil features that affect a specified use or in terms that

indicate the suitability of the soils for the use. Thus, the tables may show limitation

classes or suitability classes. Terms for the limitation classes are not limited,

somewhat limited, and very limited. The suitability ratings are expressed as well suited,

moderately suited, poorly suited, and unsuited or as good, fair, 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
240 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.

Crop Yield Estimates

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

high level of management are shown in table 6. In any given year, yields may be higher

or lower than those indicated in the table because of variations in rainfall and other

climatic factors. The land capability classification of the soils also is shown in the table.

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

conservationists, and extension agents (Fehrenbacher and others, 1978). Available

yield data from nearby counties and results of field trials and demonstrations also are

considered.

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

depends on the kind of soil and the crop. Management can include drainage; erosion

control; protection from flooding; the proper planting and seeding rates; suitable highyielding 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 (fig. 8), barnyard manure, and green manure crops; and harvesting that

ensures the smallest possible loss.

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

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

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

however, is not likely to change.

Crops other than those shown in the table are grown in the survey area, but

estimated yields are not listed because the acreage of such crops is small. The local

office of the Natural Resources Conservation Service or of the Cooperative Extension

Service can provide information about the management and productivity of the soils

for those crops.

Pasture yields.—Under good management, proper grazing is essential for the

production of high-quality forage, stand survival, and erosion control. Proper grazing

helps plants to maintain sufficient and generally vigorous top growth during the

growing season. Brush control is essential in many areas, and weed control generally

is needed. Rotation grazing and renovation also are important management practices.

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

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

sheep, or five goats) for 30 days.

Cooperative Extension Service can provide information about forage yields other than

those shown in table 6.

Land Capability Classification

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

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

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

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

grouping the soils do not take into account major and generally expensive landshaping

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

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

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

soils for forestland or for engineering purposes.

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

class, subclass, and unit (USDA, 1961). These categories indicate the degree and

kinds of limitations affecting mechanized farming systems that produce the more

commonly grown field crops, such as corn, soybeans, small grain, and hay. Only class

and subclass are used in this survey.

Capability classes, the broadest groups, are designated by the numbers 1 through

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

practical use.

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

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

of the soil limitations affecting the production of cultivated crops increases

progressively from class 1 to class 4. The limitations can affect levels of production

and the risk of permanent soil deterioration caused by erosion and other factors.

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

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

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

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

local office of the Cooperative Extension Service or the Natural Resources

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

Areas in class 8 are generally not suited to crops, pasture, or forestland without a

level of management that is impractical. These areas may have potential for other

uses, such as recreational facilities and wildlife habitat.

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

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

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

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

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

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

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

limitation is climate that is very cold or very dry.

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

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

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

restrict their use to pasture, forestland, wildlife habitat, or recreation.

The capability classification of the soils in the survey area is given in table 6.

Prime Farmland

Prime farmland is 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
Lee County, Illinois 243

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.

Over the past few decades, a trend in land use in some parts of the survey area

has been the loss of some prime farmland to industrial and urban uses (fig. 9). 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 402,250 acres, or roughly 86 percent of the total acreage in 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

Figure 9.—Encroachment of urban development into prime farmland in an area of Prairieville silt

loam, 2 to 5 percent slopes.
244 Soil Survey of

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

Table 8 lists the map unit components that are rated as hydric soils in the survey

area. 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 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.

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

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

positions on the landform.
Lee County, Illinois 245

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.

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.

Forestland Productivity and Management

The tables described in this section can help forest owners or managers plan the

use of soils for wood crops. They show the potential productivity of the soils for wood

crops and rate the soils according to the limitations that affect various aspects of

forestland management.

Forestland Productivity

Table 9 can help woodland owners or forest managers plan the use of soils for

wood crops. Only those soils commonly used for wood crops are listed.

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 woodland managers generally favor in

intermediate or improvement cuttings. They are selected on the basis of growth rate,

quality, value, and marketability.

The volume, a number, is the yield likely to be produced by the most important

trees. This number, expressed as cubic feet per acre per year, indicates the amount of

fiber produced in a fully stocked, even-aged, unmanaged stand.

Trees to plant are those that are suitable for commercial wood production.

Forestland Management

In tables 10a through 10e, interpretive ratings are given for various aspects of

forestland management. The ratings are both verbal and numerical.

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

specified aspect of forestland management. Well suited indicates that the soil has

features that are favorable for the specified management aspect and has no
246 Soil Survey of

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 management aspect. 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 management aspect. 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 management

aspect 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 aspect of forestland management (1.00) and the point at which the

soil feature is not a limitation (0.00).

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

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

point at which the potential for seedling mortality is highest (1.00) and the point at

which the potential is lowest (0.00).

The paragraphs that follow indicate the soil properties considered in rating the soils.

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.

Table 10a

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.

Table 10b

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
Lee County, Illinois 247

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.

Table 10c

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.

Table 10d

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.

Table 10e

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

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

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

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

Windbreaks and Environmental Plantings

Windbreaks protect livestock, buildings, yards, fruit trees, gardens, and cropland

from wind and snow; help to keep snow on fields; and provide food and cover for

wildlife. Field windbreaks are narrow plantings made at right angles to the prevailing

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

the soil.
248 Soil Survey of

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

reach in 20 years on various soils. The estimates in table 11 are based on

measurements and observation of established plantings that have been given

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

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

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

Conservation Service or the Cooperative Extension Service or from a commercial

nursery.

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.

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
Lee County, Illinois 249

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

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

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

pan, permeability, and toxic substances in the soil.

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

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

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

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

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

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

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

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

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

permeability, and toxic substances in the soil.

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

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

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

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

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

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

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

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

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

permeability, and toxic substances in the soil.

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

modification through cutting and filling. The ratings are based on the soil properties

that affect trafficability and erodibility. These properties are stoniness, depth to a water

table, ponding, flooding, slope, and texture of the surface layer.

Off-road motorcycle trails require little or no site preparation. They are not covered

with surfacing material or vegetation. Considerable compaction of the soil material is

likely. The ratings are based on the soil properties that influence erodibility, trafficability,

dustiness, and the ease of revegetation. These properties are stoniness, slope, depth

to a water table, ponding, flooding, and texture of the surface layer.

Golf fairways are subject to heavy foot traffic and some light vehicular traffic. Cutting

or filling may be required. Irrigation is not considered in the ratings. The ratings are

based on the soil properties that affect plant growth and trafficability after vegetation is

established. The properties that affect plant growth are reaction; depth to a water table;

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

upper 40 inches; the content of salts, sodium, or calcium carbonate; and sulfidic

materials. The properties that affect trafficability are flooding, depth to a water table,

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

surface layer. The suitability of the soil for traps, tees, roughs, and greens is not

considered in the ratings.

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
250 Soil Survey of

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, wheat, oats, and barley.

Grasses and legumes are domestic perennial grasses and herbaceous legumes.

Soil properties and features that affect the growth of grasses and legumes are depth

of the root zone, texture of the surface layer, available water capacity, wetness, surface

stoniness, flooding, and slope. Soil temperature and soil moisture also are

considerations. Examples of grasses and legumes are fescue, lovegrass, bromegrass,

clover, and alfalfa.

Wild herbaceous plants are native or naturally established grasses and forbs,

including weeds. Soil properties and features that affect the growth of these plants are

depth of the root zone, texture of the surface layer, available water capacity, wetness,

surface stoniness, and flooding. Soil temperature and soil moisture also are

considerations. Examples of wild herbaceous plants are bluestem, goldenrod,

beggarweed, wheatgrass, and grama.

Hardwood trees and woody understory produce nuts or other fruit, buds, catkins,

twigs, bark, and foliage. Soil properties and features that affect the growth of hardwood

trees and shrubs are depth of the root zone, available water capacity, and wetness.

Examples of these plants are oak, poplar, cherry, sweetgum, apple, hawthorn,

dogwood, hickory, blackberry, and blueberry. Examples of fruit-producing shrubs that

are suitable for planting on soils rated good are Russian-olive, autumn-olive, and

crabapple.

Coniferous plants furnish browse and seeds. Soil properties and features that affect

the growth of coniferous trees, shrubs, and ground cover are depth of the root zone,

available water capacity, and wetness. Examples of coniferous plants are pine, spruce,

fir, cedar, and juniper.

Wetland plants are annual and perennial wild herbaceous plants that grow on moist

or wet sites. Submerged or floating aquatic plants are excluded. Soil properties and

features affecting wetland plants are texture of the surface layer, wetness, reaction,

salinity, slope, and surface stoniness. Examples of wetland plants are smartweed, wild

millet, wildrice, saltgrass, cordgrass, rushes, sedges, and reeds.

Shallow water areas have an average depth of less than 5 feet. Some are naturally

wet areas. Others are created by dams, levees, or other water-control structures. Soil

properties and features affecting shallow water areas are depth to bedrock, wetness,

surface stoniness, slope, and permeability. Examples of shallow water areas are

marshes, waterfowl feeding areas, and ponds.
Lee County, Illinois 251

The habitat for various kinds of wildlife is described in the following paragraphs.

Habitat for openland wildlife consists of cropland (fig. 10), pasture, meadows, and

areas that are overgrown with grasses, herbs, shrubs, and vines. These areas produce

grain and seed crops, grasses and legumes, and wild herbaceous plants. Wildlife

attracted to these areas include bobwhite quail, pheasant, meadowlark, field sparrow,

cottontail, 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, woodcock, thrushes, woodpeckers,

squirrels, gray fox, raccoon, deer, and bear.

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

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

birds, muskrat, mink, and beaver.

Engineering

This section provides information for planning land uses related to urban

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

limiting features are identified. Ratings are given for building site development, sanitary

facilities, construction materials, and water management. The ratings are based on

observed performance of the soils and on the data in the tables described under the

heading “Soil Properties.”

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

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

Figure 10.—This riparian buffer strip of grasses, legumes, and trees reduces the amount of

sediment and pesticides in runoff from cropland fields. It also provides habitat for openland

and woodland wildlife.
252 Soil Survey of

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.
Lee County, Illinois 253

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

of rock fragments.

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

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

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

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

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

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

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

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

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

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

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

of rock fragments.

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

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

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

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

based on the soil properties that affect the ease of excavation and grading and the

traffic-supporting capacity. The properties that affect the ease of excavation and

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

pan, depth to a water table, ponding, flooding, the amount of large stones, and slope.

The properties that affect the traffic-supporting capacity are soil strength (as inferred

from the AASHTO group index number), subsidence, linear extensibility (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
254 Soil Survey of

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).

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.
Lee County, Illinois 255

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

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

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

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

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

smoothing practical.

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

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

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

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

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

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

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

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

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

deeper trenches, onsite investigation may be needed.

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

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

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

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

performance of roads in areas of the landfill.

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

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

workability of the soil when dry and when wet. Soils that are plastic and sticky when

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

thick cover over a layer of refuse.

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

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

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

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

for use as the final cover.

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

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

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

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

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

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

a cemented pan.

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

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

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

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

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

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

problems.

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

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

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

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

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

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

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

reaction, and content of salts, sodium, or lime.
256 Soil Survey of

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

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

and other standard construction practices are assumed.

In table 16a, 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.
Lee County, Illinois 257

The surface layer of most soils is generally preferred for topsoil because of its

organic matter content. Organic matter greatly increases the absorption and retention

of moisture and nutrients for plant growth.

Sand 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 16b, only the likelihood of finding material in suitable quantity is

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

factors that affect excavation of the material. The properties used to evaluate the soil

as a source of sand are gradation of grain sizes (as indicated by the Unified

classification of the soil), the thickness of suitable material, and the content of rock

fragments. If the bottom layer of the soil contains sand, the soil is considered a likely

source regardless of thickness. The assumption is that the sand layer below the depth

of observation exceeds the minimum thickness.

The soils are rated good, fair, or poor as potential sources of sand. A rating of good

or fair means that the material is likely to be in or below the soil. The bottom layer and

the thickest layer of the soils are assigned numerical ratings. These ratings indicate the

likelihood that the layer is a source of sand. The number 0.00 indicates that the layer is

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

between 0.00 and 1.00 indicates the degree to which the layer is a likely source.

Water Management

Tables 17a, 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
258 Soil Survey of

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.

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. 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 (fig.11). Slope, wetness, large stones, and depth to bedrock affect the

construction of terraces and diversions. A restricted rooting depth, a severe hazard of

Figure 11.—Parallel terraces help to control erosion by reducing the effective length of the slope

in this area of Osco silt loam, 5 to 10 percent slopes, eroded.
Lee County, Illinois 259

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.

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.

261

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. 12). “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
262 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

classes with specific effective diameter class limits. The broad classes are sand, silt,

and clay, ranging from the larger to the smaller.

Figure 12.—Percentages of clay, silt, and sand in the basic USDA soil textural classes.
Lee County, Illinois 263

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 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.

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.
264 Soil Survey of

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

decomposition. In table 19, the estimated content of organic matter is expressed as a

percentage, by weight, of the soil material that is less than 2 millimeters in diameter.

The content of organic matter in a soil can be maintained by returning crop residue

to the soil. Organic matter has a positive effect on available water capacity, water

infiltration, soil organism activity, and tilth. It is a source of nitrogen and other nutrients

for crops and soil organisms.

Erosion factors are shown in table 19 as the K factor (Kw and Kf) and the T factor.

Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water.

Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the

Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of

soil loss by sheet and rill erosion in tons per acre per year. The estimates are based

primarily on percentage of silt, sand, and organic matter and on soil structure and

permeability. Values of K range from 0.02 to 0.69. Other factors being equal, the higher

the value, the more susceptible the soil is to sheet and rill erosion by water.

Erosion factor Kw indicates the erodibility of the whole soil. The estimates are

modified by the presence of rock fragments.

Erosion factor Kf indicates the erodibility of the 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).

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.

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.
Lee County, Illinois 265

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.

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
266 Soil Survey of

in any year); and very frequent that it is likely to occur very often under normal weather

conditions (the chance of flooding is more than 50 percent in all months of any year).

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

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

with increasing depth; and little or no horizon development.

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

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

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

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

Water 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 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.

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. The table indicates the hardness of the restrictive layer, which can significantly

affect the ease of excavation. Depth to top is the vertical distance from the soil surface

to the upper boundary of the restrictive layer.

Subsidence is the settlement of organic soils or of saturated mineral soils of very

low density. Subsidence generally results from either desiccation and shrinkage or

oxidation of organic material, or both, following drainage. Subsidence takes place

gradually, usually over a period of several years. The table shows the expected initial

subsidence, which usually is a result of drainage, and total subsidence, which results

from a combination of factors.

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

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

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

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

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

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

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

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

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

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

other rigid structures.

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

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

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

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

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

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

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

intersect soil boundaries or soil layers is more susceptible to corrosion than the steel
Lee County, Illinois 267

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

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).

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.

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

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

is considerably higher in carbon dioxide and lower in oxygen.

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

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

aggregates produced by tillage or logging.

Alluvial fan. The fanlike deposit of a stream where it issues from a gorge upon a plain

or of a tributary stream near or at its junction with its main stream.

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.

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

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

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

redoximorphic features.

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

Backslope. The position that forms the steepest and generally linear, middle portion of

a hillslope. In profile, backslopes are commonly bounded by a convex shoulder

above and a concave footslope below.

Base saturation. The degree to which material having cation-exchange properties is

saturated with exchangeable bases (sum of Ca, Mg, Na, and K), expressed as a

percentage of the total cation-exchange capacity.

Beach deposits. Material, such as sand and gravel, that is generally laid down

parallel to an active or relict shoreline of a postglacial or glacial lake.

Glossary
272 Soil Survey of

Beach ridge. A low, essentially continuous mound of beach or beach-and-dune

material accumulated by the action of waves and currents on the backshore of a

beach, beyond the present limit of storm waves or the reach of ordinary tides, and

occurring singly or as one of a series of approximately parallel deposits. The

ridges are roughly parallel to the shoreline and represent successive positions of

an advancing shoreline.

Bedding plane. A planar or nearly planar bedding surface that visibly separates each

successive layer of stratified sediment or rock (of the same or different lithology)

from the preceding or following layer; a plane of deposition. It commonly marks a

change in the circumstances of deposition and may show a parting, a color

difference, a change in particle size, or various combinations of these. The term is

commonly applied to any bedding surface, even one that is conspicuously bent or

deformed by folding.

that is exposed at the surface.

Bedrock-controlled topography. A landscape where the configuration and relief of

the landforms are determined or strongly influenced by the underlying bedrock.

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

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

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

Blowout. A saucer-, cup-, or trough-shaped depression formed by wind erosion on a

preexisting dune or other sand deposit, especially in an area of shifting sand or

loose soil or where protective vegetation is disturbed or destroyed; the adjoining

accumulation of sand derived from the depression, where recognizable, is

commonly included. Blowouts are commonly small.

parent material and under similar climatic conditions but that have different

characteristics as a result of differences in relief and drainage.

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

calcium, potassium, magnesium, sodium, and hydrogen.

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

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

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

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

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

remains the same.

Coarse textured soil. Sand or loamy sand.

Cobble (or cobblestone). A rounded or partly rounded fragment of rock 3 to 10

inches (7.6 to 25 centimeters) in diameter.

Cobbly soil material. Material that has 15 to 35 percent, by volume, rounded or

partially rounded rock fragments 3 to 10 inches (7.6 to 25 centimeters) in

diameter. Very cobbly soil material has 35 to 60 percent of these rock fragments,

and extremely cobbly soil material has more than 60 percent.

COLE (coefficient of linear extensibility). See Linear extensibility.

Colluvium. Unconsolidated, unsorted earth material being transported or deposited

on side slopes and/or at the base of slopes by mass movement (e.g., direct

gravitational action) and by local, unconcentrated runoff.

Complex slope. Irregular or variable slope. Planning or establishing terraces,

diversions, and other water-control structures on a complex slope is difficult.

Complex, soil. A map unit of two or more kinds of soil or miscellaneous areas in such

an intricate pattern or so small in area that it is not practical to map them

separately at the selected scale of mapping. The pattern and proportion of the

soils or miscellaneous areas are somewhat similar in all areas.

Concretions. See Redoximorphic features.

Conservation cropping system. Growing crops in combination with needed cultural

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

crops and practices. Cropping systems are needed on all tilled soils. Soilimproving practices in a conservation cropping system include the use of rotations

that contain grasses and legumes and the return of crop residue to the soil. Other

practices include the use of green manure crops of grasses and legumes, proper

tillage, adequate fertilization, and weed and pest control.

Conservation tillage. A tillage system that does not invert the soil and that leaves a

protective amount of crop residue on the surface throughout the year.

Consistence, soil. Refers to the degree of cohesion and adhesion of soil material and

its resistance to deformation when ruptured. Consistence includes resistance of

soil material to rupture and to penetration; plasticity, toughness, and stickiness of

puddled soil material; and the manner in which the soil material behaves when

subject to compression. Terms describing consistence are defined in the “Soil

Survey Manual.”

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

fallow.

Coprogenous earth (sedimentary peat). A type of limnic layer composed

predominantly of fecal material derived from aquatic animals.

Corrosion (geomorphology). A process of erosion whereby rocks and soil are

removed or worn away by natural chemical processes, especially by the solvent

action of running water, but also by other reactions, such as hydrolysis, hydration,

carbonation, and oxidation.

Corrosion (soil survey interpretations). Soil-induced electrochemical or chemical

action that dissolves or weakens concrete or uncoated steel.

Cover crop. A close-growing crop grown primarily to improve and protect the soil

between periods of regular crop production, or a crop grown between trees and

vines in orchards and vineyards.

Crop residue management. Returning crop residue to the soil, which helps to

maintain soil structure, organic matter content, and fertility and helps to control

erosion.
274 Soil Survey of

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

management practices.

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.

Cutbanks cave (in tables). The walls of excavations tend to cave in or slough.

Deferred grazing. Postponing grazing or resting grazing land for a prescribed period.

Dense layer (in tables). A very firm, massive layer that has a bulk density of more than

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

affect filling and compacting.

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.

Depth, soil. Generally, the thickness of the soil over bedrock. Very deep soils are more

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.

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

material (till) that forms moraines and stratified deposits that form outwash plains,

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

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

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

covered and stabilized with vegetation but retaining its characteristic shape.

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.

upper boundary of saturation and a depth of 2 meters are saturated.

Eolian deposit. Sand-, silt-, or clay-sized clastic material transported and deposited

primarily by wind, commonly in the form of a dune or a sheet of sand or loess.

to precipitation. It receives no long-continued supply from melting snow or other

source, and its channel is above the water table at all times.

Episaturation. A type of saturation indicating a perched water table in a soil in which

saturated layers are underlain by one or more unsaturated layers within 2 meters

of the surface.

Erosion. The wearing away of the land surface by water, wind, ice, or other geologic

agents and by such processes as gravitational creep.

Erosion (geologic). Erosion caused by geologic processes acting over long

geologic periods and resulting in the wearing away of mountains and the building

up of such landscape features as flood plains and coastal plains. Synonym: natural

erosion.

Erosion (accelerated). Erosion much more rapid than geologic erosion, mainly as

a result of human or animal activities or of a catastrophe in nature, such as a fire,

that exposes the surface.

continuity of more gently sloping land surfaces and resulting from erosion or

faulting. Most commonly applied to cliffs produced by differential erosion.

Synonym: scarp.

Esker. A long, narrow, sinuous, steep-sided ridge of stratified sand and gravel

deposited as the bed of a stream flowing in an ice tunnel within or below the ice

(subglacial) or between ice walls on top of the ice of a wasting glacier and left

behind as high ground when the ice melted. Eskers range in length from less than

a kilometer to more than 160 kilometers and in height from 3 to 30 meters.

Excess lime (in tables). Excess carbonates in the soil restrict the growth of some

plants.

Fertility, soil. The quality that enables a soil to provide plant nutrients, in adequate

amounts and in proper balance, for the growth of specified plants when light,

moisture, temperature, tilth, and other growth factors are favorable.

Fibric soil material (peat). The least decomposed of all organic soil material. Peat

contains a large amount of well preserved fiber that is readily identifiable

according to botanical origin. Peat has the lowest bulk density and the highest

water content at saturation of all organic soil material.

Field moisture capacity. The moisture content of a soil, expressed as a percentage

of the ovendry weight, after the gravitational, or free, water has drained away; the

field moisture content 2 or 3 days after a soaking rain; also called normal field

capacity, normal moisture capacity, or capillary capacity.

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

First bottom. An obsolete, informal term loosely applied to the lowest flood-plain

steps that are subject to regular flooding.

Flood plain. The nearly level plain that borders a stream and is subject to flooding

unless protected artificially.

Flood-plain landforms. A variety of constructional and erosional features produced

by stream channel migration and flooding. Examples include backswamps, floodplain splays, meanders, meander belts, meander scrolls, oxbow lakes, and natural

levees.

Flood-plain splay. A fan-shaped deposit or other outspread deposit formed where an

overloaded stream breaks through a levee (natural or artificial) and deposits its

material (commonly coarse grained) on the flood plain.

Flood-plain step. An essentially flat, terrace-like alluvial surface within a valley that is

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.
276 Soil Survey of

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

soil-forming factors responsible for the formation of the solum, or true soil, from

the unconsolidated parent material.

Geomorphology. The science that treats the general configuration of the earth’s

surface; specifically the study of the classification, description, nature, origin, and

development of landforms and their relationships to underlying structures, and the

history of geologic changes as recorded by these surface features. The term is

especially applied to the genetic interpretation of landforms.

Glaciofluvial deposits. Material moved by glaciers and subsequently sorted and

deposited by streams flowing from the melting ice. The deposits are stratified and

occur in the form of outwash plains, valley trains, deltas, kames, eskers, and kame

terraces.

Glaciolacustrine deposits. Material ranging from fine clay to sand derived from

glaciers and deposited in glacial lakes mainly by glacial meltwater. Many deposits

are bedded or laminated.

Gleyed soil. Soil that formed under poor drainage, resulting in the reduction of iron

and other elements in the profile and in gray colors.

Grassed waterway. A natural or constructed waterway, typically broad and shallow,

seeded to grass as protection against erosion. Conducts surface water away from

cropland.

Gravel. Rounded or angular fragments of rock as much as 3 inches (2 millimeters to

7.6 centimeters) in diameter. An individual piece is a pebble.

Gravelly soil material. Material that has 15 to 35 percent, by volume, rounded or

angular rock fragments, not prominently flattened, as much as 3 inches (7.6

centimeters) in diameter.

Green manure crop (agronomy). A soil-improving crop grown to be plowed under in

an early stage of maturity or soon after maturity.

Ground water. Water filling all the unblocked pores of the material below the water

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 to reclaim (in tables). Reclamation is difficult after the removal of soil for

construction and other uses. Revegetation and erosion control are extremely

difficult.

Hemic soil material (mucky peat). Organic soil material intermediate in degree of

decomposition between the less decomposed fibric material and the more

decomposed sapric material.
Lee County, Illinois 277

Herbaceous peat. An accumulation of organic material, decomposed to some degree,

which is predominantly the remains of sedges, reeds, cattails, and other

herbaceous plants.

High-chroma zones. Zones having chroma of 3 or more. Typical color in areas of iron

concentrations.

High-residue crops. Such crops as small grain and corn used for grain. If properly

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.

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.

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.

Igneous rock. Rock that was formed by cooling and solidification of magma and that

has not been changed appreciably by weathering since its formation. Major

varieties include plutonic and volcanic rock (e.g., andesite, basalt, and granite).

Illuviation. The movement of soil material from one horizon to another in the soil

profile. Generally, material is removed from an upper horizon and deposited in a

lower horizon.

Impervious soil. A soil through which water, air, or roots penetrate slowly or not at all.

No soil is absolutely impervious to air and water all the time.
278 Soil Survey of

Infiltration. The downward entry of water into the immediate surface of soil or other

material, as contrasted with percolation, which is movement of water through soil

layers or material.

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

a given set of conditions.

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

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

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

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

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

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

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

follows:

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

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

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

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

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

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

More than 2.5 ............................................... very high

Interfluve. A landform composed of the relatively undissected upland or ridge

between two adjacent valleys containing streams flowing in the same general

direction. An elevated area between two drainageways that sheds water to those

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

convex shape.

Intermittent stream. A stream, or reach of a stream, that does not flow year-round but

that is commonly dry for 3 or more months out of 12 and whose channel is

generally below the local water table. It flows only during wet periods or when it

receives ground-water discharge or long, continued contributions from melting

snow or other surface and shallow subsurface sources.

Iron depletions. See Redoximorphic features.

Irrigation. Application of water to soils to assist in production of crops. Methods of

irrigation include:

Drip (or trickle).—Water is applied slowly and under low pressure to the surface of

the soil or into the soil through such applicators as emitters, porous tubing, or

perforated pipe.

Sprinkler.—Water is sprayed over the soil surface through pipes or nozzles from a

pressure system.

Kame. A low mound, knob, hummock, or short irregular ridge composed of stratified

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.

Knoll. A small, low, rounded hill rising above adjacent landforms.

Ksat. Saturated hydraulic conductivity. (See Permeability.)

Lacustrine deposit. Material deposited in lake water and exposed when the water

level is lowered or the elevation of the land is raised.

Lake bed. The bottom of a lake; a lake basin.

Lake plain. A nearly level surface marking the floor of an extinct lake filled by well

sorted, generally fine textured, stratified deposits, commonly containing varves.
Lee County, Illinois 279

Lake terrace. A narrow shelf, partly cut and partly built, produced along a lakeshore in

front of a scarp line of low cliffs and later exposed when the water level falls.

Lakeshore. A narrow strip of land in contact with or bordering a lake; especially the

beach of a lake.

Lamella. A thin (commonly less than 1 cm thick), discontinuous or continuous,

generally horizontal layer of fine material (especially clay and iron oxides) that has

been pedogenically concentrated (illuviated within a coarser textured eluviated

layer several centimeters to several decimeters thick).

Landslide. A general, encompassing term for most types of mass movement

landforms and processes involving the downslope transport and outward

deposition of soil and rock materials caused by gravitational forces; the movement

may or may not involve saturated materials. The speed and distance of movement,

as well as the amount of soil and rock material, vary greatly.

Large stones (in tables). Rock fragments 3 inches (7.6 centimeters) or more across.

Large stones adversely affect the specified use of the soil.

Leaching. The removal of soluble material from soil or other material by percolating

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

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

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
Lee County, Illinois 283

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.

2.0 millimeters in diameter. Most sand grains consist of quartz. As a soil textural

class, a soil that is 85 percent or more sand and not more than 10 percent clay.

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.

Saturated hydraulic conductivity (Ksat). See Permeability.

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.

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.

Slow refill (in tables). The slow filling of ponds, resulting from restricted permeability in

the soil.

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.

or 15 to 24 inches (38 to 60 centimeters) in length if flat.

Stream channel. The hollow bed where a natural stream of surface water flows or

may flow; the deepest or central part of the bed, formed by the main current and

covered more or less continuously by water.

Stream terrace. One of a series of platforms in a stream valley, flanking and more or

less parallel to the stream channel, 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.

Subsidence. The potential decrease in surface elevation as a result of the drainage of

wet soils that have organic layers or semifluid, mineral layers. Subsidence, as a

result of drainage, is attributed to (1) shrinkage from drying, (2) consolidation

because of the loss of ground-water buoyancy, (3) compaction from tillage or

manipulation, (4) wind erosion, (5) burning, and (6) biochemical oxidation.

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.

(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.”
286 Soil Survey of

Surface soil. The A, E, AB, and EB horizons, considered collectively. It includes all

subdivisions of these horizons.

Swale. A slight depression in the midst of generally level land. A shallow depression in

an undulating ground moraine due to uneven glacial deposition.

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.

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.

Trace elements. Chemical elements, for example, zinc, cobalt, manganese, copper,

and iron, in soils in extremely small amounts. They are essential to plant growth.

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.

Weathering. All physical disintegration, chemical decomposition, and biologically

induced changes in rocks or other deposits at or near the earth’s surface by
Lee County, Illinois 287

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.

Table 16b.--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)
