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. Significant

funding towards the acceleration and completion of this survey was contributed by the

State of Wisconsin Department of Administration, Land Information Board, through the

State Soil Survey Initiative. This survey was made cooperatively by the Natural

Resources Conservation Service and the Research Division of the College of

Agricultural and Life Sciences, University of Wisconsin.

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

descriptions were approved in 2005. Digitizing of the survey was completed by the

Madison, Wisconsin, NRCS digitizing unit in 2006. The manuscript was compiled in

2006. Unless otherwise indicated, statements in this publication refer to conditions in the

survey area in 2006. 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 publication is

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

treatment decisions. Statements made in this publication 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. 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.

How This Survey Was Made

This survey was made to provide updated information about the soils and

miscellaneous areas in the survey area (fig. 1), which is in Major Land Resource

Areas 90A, Wisconsin and Minnesota Thin Loess and Till, Northern Part, and 90B,

Wisconsin and Minnesota Thin Loess and Till, Southern Part. Major land resource

areas (MLRAs) are geographically associated land resource units that share a

common land use, elevation, topography, climate, water, soils, and vegetation (USDA,

2006). Rusk County is a subset of MLRAs 90A and 90B. Map unit design is based on

documentation of the occurrence of the soils throughout the MLRAs.

The information in this survey includes a brief description of the soils and

miscellaneous areas. Interpretive tables showing soil properties and the subsequent

effects on suitability, limitations, and management for specified uses are also available

for this survey area through a link to the Web Soil Survey of the Natural Resources

Conservation Service from the NRCS Soils Web site (http://soils.usda.gov). During the

fieldwork for this survey, 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 of

landscape or segment of the landscape. By observing the soils and miscellaneous

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

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

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

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

location on the landscape.

Individual soils on the landscape commonly merge into one another as their

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

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

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

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

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

Soil scientists recorded the characteristics of the soil profiles that they observed.

The maximum depth of observation was about 80 inches (6.7 feet). Soil scientists

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

zone in which the soil moisture status is wet within certain depths in most years, but

they cannot predict that this zone 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 adjacent survey areas. Differences are the result of a better

knowledge of soils, modifications in series concepts, or variations in the intensity of

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

This section relates the soils in the survey area to the major factors of soil formation

and describes the system of soil classification.

Formation of the Soils

Soil is produced by the action of soil-forming processes on materials deposited or

accumulated by geologic forces. The characteristics and properties of soil in a given

area are determined by (1) the physical and mineralogical composition of the parent

material; (2) the climate under which the soil material has accumulated and existed

since accumulation; (3) the living organisms on and in the soil, mainly vegetation;

(4) relief, or topography; and (5) the length of time the forces of soil formation have

acted on the soil material. The relative effect of each of these factors is reflected in the

soil profile.

The interaction of these factors during the transformation of the parent material into

soil generates complex physical, chemical, and biological processes causing minerals

to become weathered and organic matter to accumulate. Material in suspension or in

solution moves downward through the soil to form definite layers, or horizons, in the

soil. These layers—surface layer, subsurface layer, subsoil, and substratum—are

defined in the Glossary.

In Rusk County, differences in parent material, vegetation, relief, and time account

for most of the differences among the soils. Climate is fairly uniform throughout the

county.

All five factors of soil formation are interrelated. When one factor changes, changes

in the other four factors result. The following paragraphs describe the factors of soil

formation as they relate to the soils in the survey area.

Parent Material

Parent material is the original deposit of mineral or organic material before it is

altered into soil. Rusk County has a diversity of parent materials, mainly as a result of

the repeated glaciations in the region. The nature of the parent material largely

determines the physical and chemical properties of the soil. Soils that formed in parent

material composed mainly of sand and gravel have very high saturated hydraulic

conductivity (permeability) and very low fertility. In general, permeability decreases

and fertility increases as the content of silt and clay increases in a soil.

Glaciers advanced and retreated over the surface of the survey area a number of

times during the Late Wisconsinan glacial period, which occurred between 25,000 and

9,500 years ago. Each glacial advance left a mineral deposit, which today forms a

complex mosaic of parent materials. Post-glacial deposits also occur, including

windblown material, alluvial deposits, and organic accumulations. An actively moving

glacier can erode the previously existing glacial deposits to a depth of 20 feet or more.

This eroded material combined with eroded bedrock is known collectively as drift. The

drift is transported by moving ice and is eventually deposited in various ways. The

nature of the transported material and the mode of deposition determine the

characteristics of the parent material.

Formation and Classification of

the Soils
6 Soil Survey of

Material deposited at the ice margins is called till; landforms composed of till are

called moraines. Till is a poorly sorted mixture of sand, silt, and clay particles as well

as gravel, cobbles, stones, and boulders. There are two main types of moraines—

terminal and ground. Terminal moraines formed at the leading edge of a glacial

advance, and ground moraines formed beneath the moving ice. The material

deposited beneath the ice was compacted and is called dense till. The high bulk

density that is characteristic of this material can also be observed in the soils that

formed in it.

Drumlins, another type of glacial landform, also occur in Rusk County. Drumlins are

typically long, low ridges molded by a moving glacier. In some places the till was

covered by windblown, silty sediments called loess.

Sediment deposited by glacial meltwater is called outwash. Outwash occurs on

such glaciofluvial landforms as outwash plains and pitted outwash plains. Kames and

eskers are glaciofluvial landforms that were deposited by meltwater flowing beneath

the glacier. Typically, outwash deposits consist of sand and gravel; in places, sandy

outwash is blanketed by thin deposits of loamy, post-glacial alluvial sediments or

windblown deposits. Glacial meltwater that slowed or became impounded produced

glacial lakes. Some of the depressions that filled with glacial meltwater are still lakes

today, but many others drained over time. The areas that drained became

glaciolacustrine landforms. Soils that formed in glaciolacustrine sediments are typically

sandy, silty, or clayey or are stratified with these textures.

Some areas of Rusk County have more recent deposits. Recent alluvial deposits

occur on the flood plains along watercourses, and organic deposits occur within

wetlands. Flood plains and wetlands can occur on moraines, outwash plains, or lake

plains, which are the three main landform types in the survey area.

Climate

Climate is the average of weather conditions occurring over many years. Climate

can fluctuate greatly over time, as evidenced by Pleistocene continental glaciation.

Weather is a dynamic force in nature; its agents are precipitation, wind, and

temperature. Ultimately the energy that drives the global climatic, atmospheric, and

hydrologic cycles comes from the sun. Climate is the result of the redistribution of

solar energy through air, water, and soil.

Computerized mathematical models, based on many years of data collection and

analysis, have been developed. These models can be used to predict many aspects of

atmospheric and hydrologic cycles and their relationship to soil. One such

mathematical model, the Revised Universal Soil Loss Equation (RUSLE), is used to

predict the influence of climatic variables on soil erosion. Other complex but useful

models can help explain important soil-climate interactions, such as soil moisture

status or the cyclic fluctuation of soil temperature.

Precipitation is the source of most soil water. Soil water is vital for plant growth, soil

microbial activity, and many aspects of soil development. Water in soil dissolves and

transports soil minerals in a net downward movement. Freeze-thaw and wet-dry cycles

help mix soil and create soil structure. Furthermore, most soil chemical reactions that

cycle mineral nutrients through ecosystems take place in aqueous solution. In other

words, the structure and function of all major terrestrial ecosystems (forest, prairie,

tundra, and even desert) depend on precipitation infiltrating soil. The amount and

duration of soil water have a great effect on soil properties. Soils that are frequently

saturated have a higher content of organic matter and commonly exhibit gray or highly

mottled color patterns. Drier soils tend to contain less organic matter and have brighter

colors.

Temperature influences soil formation in several ways. Colder climates allow the

accumulation of organic matter in soils because the rate of decomposition is controlled

by temperature. The rates of all soil chemical reactions increase with increasing

temperature. Thus, soils in warmer climates are more highly weathered and store

fewer nutrients in general than soils in colder climates.

Wind is another dynamic force in nature and in soil formation. The surface of many

soils is affected by wind erosion or windblown deposits. Wind carries many small

particles, sometimes over long distances; dust from the eastern hemisphere has been

found in soils in the western hemisphere.

The present-day climate of Rusk County is characterized by long winters and a net

excess of precipitation over potential evapotranspiration. In other words, the climate is

generally cold and moist and results in a slow accumulation of soil organic matter over

time. A warmer climate would alter that trend. Variations in topography lead to marked

differences in micro-climate, that is, the climate of smaller areas within the landscape.

For example, south-facing slopes are measurably warmer and drier than north-facing

slopes and low spots on the landscape are commonly colder and subject to more

frequent frosts than the surrounding uplands. These topo-climatic effects are important

factors that help to explain local variations in soils and vegetation.

Living Organisms

Plants, animals, and micro-organisms interact to greatly influence the formation of

soils. Plants produce the bulk of the organic matter that darkens and enriches the

topsoil. They also produce substances that break down minerals and release nutrients

into the soil. Animals also influence soil formation. Burrowing animals (including

mammals, worms, and insects) mix the soil, and other land animals cycle nutrients

extensively to and from the soil.

Micro-organisms are an especially vital component of soils. Most important soil

chemical reactions involve micro-organisms, such as bacteria, actinomycetes, or fungi.

An example is the critical process of fixing atmospheric nitrogen into a form useful for

plants by certain types of symbiotic bacteria. Micro-organisms also serve a crucial role

as decomposers, completing the cycle of plant to animal to soil and back to plant

again.

The soils of Rusk County formed mainly under forest vegetation. However,

extensive plant communities dominated by grass, sedges, or shrubs are common in

areas subject to prolonged wetness or following widespread disturbance (for example,

wildfire or drought). Forest soils have a characteristic set of properties, including a leaf

litter layer at the surface, a light-colored topsoil, and an increase in clay content in the

subsoil. Disturbance may alter vegetation rapidly, but soil properties that indicate past

vegetation will remain. Over time, however, soil properties will change to reflect the

influence of the current vegetation. For example, many agricultural soils that were once

forested typically have the characteristic darker surface layer of soils that formed

under grasslands, but they retain the clay-enriched subsoil that is typical of forest soils.

The dark topsoil forms as a result of beneficial agricultural practices, such as crop

rotations, soil amendments, and erosion control.

Where lack of oxygen retards the decomposition of organic material in soils, as in

swamps and bogs, dead plants accumulate to form a soil that consists entirely of peat.

Soils that formed in peat are referred to as organic soils, or Histosols, and have

properties distinctly different from those of mineral soils. For example, organic soils

have very low bearing strength and a very high ability to retain water. Rusk County has

an abundance of organic soils.

Humans have a profound effect on soil formation. Agriculture and land development

can expose soils to accelerated erosion and a potential loss of productivity.

Conservation practices can reduce these negative impacts, however, and can improve

sustainability for both agricultural producers and land developers.

Topography

Topography is an important factor in soil formation because it affects drainage,

aeration, and erosion.

Because topography influences runoff and drainage, it can affect the types of

vegetation present and the chemical changes on and in the soil. Soil profile

development occurs most rapidly on well drained, gentle slopes. Profile development is

very slow on steep slopes, where runoff is rapid, the rate of water infiltration is slow,

and geologic erosion removes the surface soil almost as quickly as it forms. Excessive

runoff reduces the amount of water that is available for leaching the soil and for use by

plants, and it can increase the hazard of erosion. The position of a soil on the

landscape affects the drainage class of the soil. Drainage has a distinct influence on

soil formation.

Differences in topography can account for the formation of different soils in similar

kinds of parent material.

Time

The passage of time is necessary for the formation of soil. Fresh deposits are not

considered soil until the other soil-forming factors have acted upon them. Some soilforming processes take place over hundreds of years, and the longer they continue,

the more pronounced their effect. With other soil-forming processes, however, only a

short period of time is required for the effects to become observable. In forest soils,

after a clay-enriched subsoil is formed, the clay translocation process (known as

eluviation) continues to move the clay to a greater depth in the soil. This process

increases the thickness of the light-colored topsoil and penetrates and degrades the

subsoil. Older soils have thicker horizons that extend deeper than those of younger

soils and have more highly weathered minerals.

On the geological time-scale, the parent materials in Rusk County are very young.

Moreover, the present-day climate and vegetation under which the soils are forming

are relatively recent developments. The forests of northern Wisconsin were

established about 3,000 years ago. The climate as it exists today is probably less than

2,000 years old. Thus, the soils of Rusk County are of even more recent vintage than

the modern climate or vegetation type, and they are constantly changing. Some soil

chemical properties change over the course of a single year. This fact illustrates the

dynamic nature of soil-forming processes and indicates the potential for change in the

future.

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.

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).
Rusk County, Wisconsin 9

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 aquolls, 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,

mineralogy class, cation-exchange activity class, soil temperature regime, soil depth,

and reaction class. A family name consists of the name of a subgroup preceded by

terms that indicate soil properties. An example is fine-loamy, mixed, active, 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 Official Series Descriptions (OSDs) provide the most current information about

the series mapped in Rusk County. These descriptions are available on the Web at

The map units delineated on the soil maps for this survey area represent the soils

or miscellaneous areas in the survey area. These soils or miscellaneous areas are

listed as individual components in the map unit descriptions. 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 provided in various

tables, which are accessible from the Soil Data Explorer/Soil Reports tab in Web 

Soil Survey. Web Soil Survey can be accessed from the NRCS Soils Web site 

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

A map unit delineation on the soil maps represents an area on the landscape. It is

identified by differences in the properties and taxonomic classification of components

and by the percentage of each component in the map unit.

Components that are dissimilar, or contrasting, are identified in the map unit

description. Dissimilar components are those that have properties and behavioral

characteristics divergent enough from those of the major components to affect use or

to require different management. 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.

Components that are similar to the major components (noncontrasting) are not

identified in the map unit description. Similar components are those that have

properties and behavioral characteristics similar enough to those of the major

components that they do not affect use or require different management.

The presence of multiple 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 segments that have

similar use and management requirements. The delineation of such landscape

segments on the map provides sufficient information for the development of resource

plans, but if intensive use of small areas is planned, onsite investigation is needed to

define and locate the soils and miscellaneous areas.

An identifying symbol is used for each map unit on the soil maps. This symbol

precedes the map unit name in the map unit descriptions. Each description includes

general information about the unit. The map unit descriptions include representative

values in feet and the months in which a wet zone (a zone in which the soil moisture

status is wet) is highest and lowest in the soil profile and ponding is shallowest and

deepest on the soil surface. The descriptions also include the frequency of flooding (if

it occurs) and the months in which flooding is most frequent and least frequent. The

“Water Features” report provides a complete display of this data for every month of the

year. The available water capacity given in each map unit description is calculated for

all horizons in the upper 60 inches of the soil profile. The organic matter content

displayed in each map unit description is calculated for all horizons in the upper 10

inches of the soil profile, except those that represent the surface duff layer on forested

soils. The “Physical Soil Properties” report provides a complete display of available

water capacity and organic matter content by horizon.

Some of the principal hazards and limitations to be considered in planning for

specific uses are described in other sections of this survey.

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

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

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

arrangement.

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

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

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

series is divided into soil phases. The name of a soil phase commonly indicates a

feature that affects use or management.

A map unit is named for the component or components that make up a dominant

percentage of the map unit. Many map units consist of one dominant component.

These map units are consociations.

Some map units are made up of two or more dominant components. These map

units are complexes or undifferentiated groups.

A complex consists of two or more components in such an intricate pattern or in

such small areas that they cannot be shown separately on the maps. Attempting to

delineate the individual components of a complex would result in excessive clutter that

could make the map illegible. The pattern and proportion of the components in a

complex are somewhat similar in all areas.

An undifferentiated group is made up of two or more components that could be

mapped individually but are mapped as one unit because similar interpretations can

be made for use and management. The pattern and proportion of the components in a

mapped area are not uniform. An area can be made up of only one of the dominant

components, or it can be made up of all of them.

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

and support little or no vegetation.

The table “Acreage and Proportionate Extent of the Soils” provides a complete

listing of the detailed soil map units in Rusk County. 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; for agricultural

waste management; 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 gravel, sand, reclamation

material, 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 for this survey, which are accessible via the Soil Data

Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov), 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

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 discussed, 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

obtaining detailed information from the local office of the Natural Resources

Conservation Service or the Cooperative Extension Service.

Cropland Management Considerations

The main concerns in managing nonirrigated cropland are conserving moisture,

controlling wind erosion and water erosion, and maintaining soil fertility.

Conserving moisture consists primarily of reducing the evaporation and runoff rates

and increasing the water infiltration rate. Applying conservation tillage and

conservation cropping systems, farming on the contour, stripcropping, establishing

field windbreaks, and leaving crop residue on the surface conserve moisture.

Generally, a combination of several practices is needed to control wind erosion and

water erosion. Conservation tillage, stripcropping, field windbreaks, contour farming,

conservation cropping systems, crop residue management, terraces, diversions, and

grassed waterways help to prevent excessive soil loss.

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

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

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

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

productivity, although the level of fertility can be reduced even in areas where erosion

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

fertilizer.

Additional considerations are as follows:

Lime content, limited available water capacity, limited content of organic matter,

potential poor tilth and compaction, and restricted permeability.—These limitations can

be minimized by incorporating green manure crops, manure, or crop residue into the

soil; applying a system of conservation tillage; and using conservation cropping

systems. Also, crops may respond well to additions of phosphate fertilizer to soils that

have a high content of lime.

Potential for ground-water contamination.—The proper use of nutrients and

pesticides can reduce the risk of ground-water contamination.

Potential for surface-water contamination.—The risk of surface-water contamination

can be reduced by the proper use of nutrients and pesticides and by conservation

farming practices that reduce the runoff rate.

Surface crusting.—This limitation retards seedling development after periods of

heavy rainfall.
Rusk County, Wisconsin 123

Surface rock fragments.—This limitation causes rapid wear of tillage equipment. It

cannot be easily overcome.

Surface stones.—Stones or boulders on or near the surface can hinder normal

tillage unless they are removed.

Salt content.—In areas where this is a limitation, only salt-tolerant crops should be

grown.

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

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

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

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

leaches plant nutrients, causes erosion, and increases wetness.

Yields per Acre

The tables described in this section are available through the Soil Data Explorer/Soil

Reports tab in Web Soil Survey (http://soils.usda.gov). The titles are:

• “Irrigated and Nonirrigated Yields by Map Unit”

• “Irrigated and Nonirrigated Yields by Map Unit Component”

• “Irrigated Yields by Map Unit”

• “Irrigated Yields by Map Unit Component”

• “Nonirrigated Yields by Map Unit”

• “Nonirrigated Yields by Map Unit Component”

The average yields per acre shown in the yields tables for this survey are those that

can be expected of the principal crops under a high level of management. In any given

year, yields may be higher or lower than those indicated in the tables because of

variations in rainfall and other climatic factors. The land capability classification of map

units in the survey area also is shown in the tables.

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

conservationists, and extension agents. Available yield data from nearby counties and

results of field trials and demonstrations 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, and protection from flooding; the proper planting and seeding rates; suitable

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

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

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

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

smallest possible loss.

For yields of irrigated crops, it is assumed that the irrigation system is adapted to

the soils and to the crops grown, that good-quality irrigation water is uniformly applied

as needed, and that tillage is kept to a minimum.

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

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

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

is not likely to change.

Crops other than those shown in the yields tables 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.
124 Soil Survey of

Pasture and Hayland Interpretations

The soils in the survey area have been assigned to forage suitability groups. The

soils in each group are similar enough to be suited to the same species of grasses or

legumes, have similar limitations and hazards, require similar management, and have

similar productivity levels and other responses to management. Detailed descriptions

of forage suitability groups are available at local offices of the Natural Resources

Conservation Service.

Under good management, proper grazing is essential for the production of highquality forage, stand survival, and erosion control. Proper grazing helps plants to

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

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

Rotation grazing and pasture renovation also are important management practices.

Pasture yields are expressed in terms of animal unit months. An animal unit month

(AUM) is the amount of forage required by one mature cow of approximately 1,000

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

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

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

in the yields tables.

Land Capability Classification

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

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

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

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

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

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

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

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

soils for forestland or for engineering purposes.

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

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

kinds of limitations affecting mechanized farming systems that produce the more

commonly grown field crops, such as corn, small grain, cotton, hay, and field-grown

vegetables. Only class and subclass are used in this survey.

Capability classes, the broadest groups, are designated by 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 forest land. 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.

Areas in class 8 are generally not suitable for crops, pasture, or forest land 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
Rusk County, Wisconsin 125

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

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

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

limitation is climate that is very cold or very dry.

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

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

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

restrict their use mainly to pasture, forest land, wildlife habitat, or recreation.

The capability classification of map units in the survey area is given in yields tables

available in Web Soil Survey.

Important Farmlands

The table “Prime and Other Important Farmlands,” which is available through the

Soil Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov), lists the

map units in the survey area that are considered important farmlands. Important

farmlands consist of prime farmland, unique farmland, and farmland of statewide or

local importance. This list does not constitute a recommendation for a particular land

use.

In an effort to identify the extent and location of important farmlands, the Natural

Resources Conservation Service, in cooperation with other interested Federal, State,

and local government organizations, has inventoried land that can be used for the

production of the Nation’s food supply.

Prime farmland is of major importance in meeting the Nation’s short- and longrange needs for food and fiber. Because the supply of high-quality farmland is limited,

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

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

prime farmland.

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

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

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

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

areas. The soil quality, 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. The water

supply is dependable and of adequate quality. Prime farmland 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.

For some of the soils identified in the table as prime farmland, 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.

A recent trend in land use in some areas has been the loss of some prime farmland

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

on marginal lands, which generally are more erodible, droughty, and less productive

and cannot be easily cultivated.

Unique farmland is land other than prime farmland that is used for the production of

specific high-value food and fiber crops, such as citrus, tree nuts, olives, cranberries,
126 Soil Survey of

and other fruits and vegetables. It has the special combination of soil quality, growing

season, moisture supply, temperature, humidity, air drainage, elevation, and aspect

needed for the soil to economically produce sustainable high yields of these crops

when properly managed. The water supply is dependable and of adequate quality.

Nearness to markets is an additional consideration. Unique farmland is not based on

national criteria. It commonly is in areas where there is a special microclimate, such as

the wine country in California.

In some areas, land that does not meet the criteria for prime or unique farmland is

considered to be farmland of statewide importance for the production of food, feed,

fiber, forage, and oilseed crops. The criteria for defining and delineating farmland of

statewide importance are determined by the appropriate State agencies. Generally,

this land includes areas of soils that nearly meet the requirements for prime farmland

and that economically produce high yields of crops when treated and managed

according to acceptable farming methods. Some areas may produce as high a yield as

prime farmland if conditions are favorable. Farmland of statewide importance may

include tracts of land that have been designated for agriculture by State law.

In some areas that are not identified as having national or statewide importance,

land is considered to be farmland of local importance for the production of food, feed,

fiber, forage, and oilseed crops. This farmland is identified by the appropriate local

agencies. Farmland of local importance may include tracts of land that have been

designated for agriculture by local ordinance.

Windbreaks and Environmental Plantings

Windbreaks protect livestock, buildings, and yards from wind and snow. They also

protect fruit trees and gardens, and they furnish habitat for wildlife. Several rows of

low- and high-growing broadleaf and coniferous trees and shrubs provide the most

protection.

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

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

soil. Field windbreaks protect cropland and crops from wind, help to keep snow on the

fields, and provide food and cover for wildlife.

Environmental plantings help to beautify and screen houses and other buildings and

to abate noise. The plants, mostly evergreen shrubs and trees, are closely spaced. To

ensure plant survival, a healthy planting stock of suitable species should be planted

properly on a well prepared site and maintained in good condition.

Windbreaks are often planted on land that did not originally support trees.

Knowledge of how trees perform on such land can be gained only by observing and

recording the performance of trees that have been planted and have survived. Many

popular windbreak species are not indigenous to the areas in which they are planted.

Each tree or shrub species has certain climatic and physiographic limits. Within

these parameters, a tree or shrub may grow well or grow poorly, depending on the

characteristics of the soil. Each tree or shrub has definable potential heights in a given

physiographic area and under a given climate. Accurate definitions of potential heights

are necessary when a windbreak is planned and designed.

Information on planning windbreaks and screens and planting and caring for trees

and shrubs can be obtained from local offices of the Natural Resources Conservation

Service or the Cooperative Extension Service or from a nursery.

Conservation Tree/Shrub Suitability Groups

Conservation tree/shrub suitability groups consist of soils in which the kinds and

degrees of the hazards and limitations that affect the survival and growth of trees and

shrubs in conservation plantings are about the same. The conservation tree/shrub
Rusk County, Wisconsin 127

suitability groups assigned to the soils in the survey area are available from the local

office of the Natural Resources Conservation Service. Descriptions of the groups are

provided in the “National Forestry Manual,” which is available in local offices of the

Natural Resources Conservation Service or on the Internet.

Forestland Management

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

use of soils for wood crops. They rate the soils according to the limitations that affect

various aspects of forestland management. The tables are accessible through the Soil

Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). The titles

are:

• “Haul Roads, Log Landings, and Soil Rutting on Forestland”

• “Hazard of Erosion and Suitability for Roads on Forestland”

• “Forestland Planting and Harvesting”

• “Forestland Site Preparation”

• “Damage by Fire and Seedling Mortality on Forestland”

In these tables, 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

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 fire damage and seedling mortality are expressed as low,

moderate, and high. Where these terms are used, the numerical ratings indicate

gradations between the point at which the potential for fire damage or seedling

mortality is highest (1.00) and the point at which the potential is lowest (0.00).

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

More detailed information about the criteria used in the ratings is available in the

“National Forestry Manual,” which is available in local offices of the Natural Resources

Conservation Service or on the Internet.

For limitations affecting construction of haul roads and log landings, the ratings are

based on slope, flooding, permafrost, plasticity index, the hazard of soil slippage,

content of sand, the Unified classification, rock fragments on or below the surface,

depth to a restrictive layer that is indurated, depth to a water table, and ponding. The

limitations are described as slight, moderate, or severe. A rating of slight indicates that

no significant limitations affect construction activities, moderate indicates that one or

more limitations can cause some difficulty in construction, and severe indicates that

one or more limitations can make construction very difficult or very costly.
128 Soil Survey of

The ratings of suitability for log landings are based on slope, rock fragments on the

surface, plasticity index, content of sand, the Unified classification, depth to a water

table, ponding, flooding, and the hazard of soil slippage. The soils are described as

well suited, moderately suited, or poorly suited to use as log landings.

Ratings in the column soil rutting hazard are based on depth to a water table, rock

fragments on or below the surface, the Unified classification, depth to a restrictive

layer, and slope. Ruts form as a result of the operation of forest equipment. The hazard

is described as slight, moderate, or severe. A rating of slight indicates that the soil is

subject to little or no rutting, moderate indicates that rutting is likely, and severe

indicates that ruts form readily.

Ratings in the column hazard of off-road or off-trail erosion are based on slope and

on soil erosion factor K. The soil loss is caused by sheet or rill erosion in off-road or

off-trail areas where 50 to 75 percent of the surface has been exposed by logging,

grazing, mining, or other kinds of disturbance. The hazard is described as slight,

moderate, severe, or very severe. A rating of slight indicates that erosion is unlikely

under ordinary climatic conditions; moderate indicates that some erosion is likely and

that erosion-control measures may be needed; severe indicates that erosion is very

likely and that erosion-control measures, including revegetation of bare areas, are

advised; and very severe indicates that significant erosion is expected, loss of soil

productivity and 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

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

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

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

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

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

expected, that the roads or trails require frequent maintenance, and that costly

erosion-control measures are needed.

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

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

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

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

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

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

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

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

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

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

before seedlings are planted.

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

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

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

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

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

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

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

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

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

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

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

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

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

about 3 feet is considered in the ratings.
Rusk County, Wisconsin 129

Ratings in the column potential for damage to soil by fire are based on texture of the

surface layer, content of rock fragments and organic matter in the surface layer,

thickness of the surface layer, and slope. The soils are described as having a low,

moderate, or high potential for this kind of damage. The ratings indicate an evaluation

of the potential impact of prescribed fires or wildfires that are intense enough to

remove the duff layer and consume organic matter in the surface layer.

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

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

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

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

Forest Habitat Types

Joseph A. Kovach, forest ecologist/silviculturist, Division of Forestry, Wisconsin Department of Natural

Resources, helped prepare this section.

The forest habitat type classification system (FHTCS) is a site classification system

based on the floristic composition of plant communities. The system depends on the

identification of potential climax associations, repeatable patterns in the composition of

the understory vegetation, and differential understory species. It groups land units with

similar capacity to produce vegetation. The floristic composition of the plant community

is used as an integrated indicator of those environmental factors that affect species

reproduction, growth, competition, and community development. This classification

system enables the recognition of ecologically similar landscape units and vegetation

communities. It is a system for classifying forest plant communities and the sites on

which they develop.

A forest habitat type is an aggregation of sites (units of land) capable of producing

similar late-successional (potential climax) forest plant communities. Each

recognizable habitat type represents a relatively narrow segment of environmental

variation that is characterized by a certain limited potential for vegetation development.

Although at any given time a habitat type can support a variety of disturbance-induced

(seral) plant communities, the ultimate product of succession is presumed to be a

similar climax community. Field identification of a habitat type provides a convenient

label (habitat type name) for a given site and places that site in the context of a larger

group of sites that share similar ecological traits.

Forest habitat types are characterized by plant associations, not by individual

indicator species. Differential (diagnostic) species combinations in the understory flora

are used to identify habitat types at any successional stage, but these combinations

have meaning only in the context of the specific habitat types or groups being

compared.

The forest habitat types in Rusk County can be identified and interpreted using

Field Guide to Forest Habitat Types of Northern Wisconsin, 2nd edition (Kotar and

others, 2002). The guide provides keys to habitat type identification based on the

presence or absence of differential understory species; describes the characteristic

understory species composition, the common forest cover types, and the expected

successional trends; and summarizes management implications for each habitat type.

Management considerations include inherent site capability (biological potential),

potential responses to disturbance, competition, successional trends, potential cover

types, and expected suitability and productivity for specific tree species. Additional

interpretive information is available in Wisconsin Forest Statistics, 1996: Analysis by

Habitat Type Class (Kotar and others, 1999).

Although soil map units do not coincide exactly with habitat types, there is a strong

correlation between them. Soil moisture and nutrient regimes are key factors

determining habitat type occurrence. Habitat types for the soils in Rusk County are

shown in the “Forest Habitat Types” table at the end of this section. A single habitat
130 Soil Survey of

type is considered dominant if it constitutes more than 60 percent coverage (one

habitat type that has more than 60 percent occurrence). If no habitat types are

dominant but two types with 25 to 59 percent occurrence add up to more than 70

percent, then they would be considered codominant. A common habitat type is listed

when the expected frequency of occurrence is 15 to 55 percent and the requirements

for identification as codominant are not met.

The following paragraphs briefly describe the habitat types in the county. The types

are listed generally in order from the poorest and least productive to the most

productive.

Region 1 Habitat Types (occurring only in the western one-third of Rusk County)

PArVAm—Pinus strobus-Acer rubrum/Vaccinium angustifolium-Amphicarpa

bracteata habitat type. The common name is Eastern white pine-Red maple/

Blueberry-Hog peanut. The presumed potential climax overstory is dominated by

eastern white pine, red maple, northern red oak, and white oak. Currently, common

cover types include any mixture of aspen, white oak, red oak, and red maple.

Overstory associates can include white birch, northern pin oak, bur oak, white pine,

red pine, and jack pine. The dominant ground flora commonly includes grasses and

sedges, hazelnut, juneberry, blackberries, blueberry, bracken fern, bigleaf aster, hog

peanut, wild sarsaparilla, and red maple seedlings.

The moisture regime is dry or dry-mesic, and the nutrient regime is poor or medium.

All of the pines exhibit excellent potential productivity in areas of this habitat type, but

intense competition often limits opportunities for the establishment and maintenance of

jack pine. Aspen and paper birch can exhibit good growth and productivity, but the

oaks and red maple demonstrate only moderate productivity.

This habitat type is not common but can occur in areas of outwash in the

southwestern part of the county.

AVDe—Acer saccharum/Vaccinium angustifolium-Desmodium glutinosum

habitat type. The common name is Sugar maple/Blueberry-Pointed-leaved tick trefoil.

The presumed potential climax overstory is dominated by sugar maple, red maple,

American basswood, and white ash but may also include northern red oak, white oak,

and eastern white pine. Currently, common cover types include any mixture of aspen,

white oak, red oak, and red maple. Overstory associates can include sugar maple,

basswood, white pine, and white birch. The dominant ground flora commonly includes

grasses and sedges, maple-leaved viburnum, hazelnut, blackberries, bracken fern,

bigleaf aster, pointed-leaved tick trefoil, hog peanut, wild sarsaparilla, interrupted fern,

ironwood, and seedlings of red maple and sugar maple.

The moisture regime is dry-mesic, and the nutrient regime is medium. Trees

exhibiting excellent potential productivity include white pine, red pine, white birch, and

aspen. Also, white oak, red oak, and red maple can exhibit good growth and

productivity. The mesic hardwoods (sugar maple, basswood, and white ash) offer only

moderate to poor potential productivity.

This habitat type is common on rolling moraines and outwash plains along the

western side of the county.

AAt—Acer saccharum/Athyrium filix-femina habitat type. The common name is

Sugar maple/Lady fern. The presumed potential climax overstory is dominated by

sugar maple, basswood, white ash, and red maple. Currently, common cover types

include any mixture of northern red oak, white oak, red maple, sugar maple, and

aspen. Common overstory associates include American basswood, white ash, eastern

white pine, and white birch. The dominant ground flora commonly includes grasses

and sedges, sugar maple seedlings, ironwood seedlings, hazelnut, bigleaf aster, hog

peanut, pointed-leaved tick trefoil, lady fern, interrupted fern, bracken fern, early

meadow rue, sweet cicely, trilliums, sessile-leaved bellwort, wild sarsaparilla, and

maple-leaved viburnum.
Rusk County, Wisconsin 131

The moisture regime is dry-mesic, and the nutrient regime is medium or rich. Mesic

hardwoods (sugar maple, basswood, white ash, and red maple) are very competitive,

and potential productivity is good. Red oak, white oak, and white pine demonstrate

excellent productivity but require significant disturbance for successful regeneration.

Following severe disturbance, aspen and paper birch can demonstrate excellent

productivity as pioneers.

This habitat type is common on moraines, outwash plains, and glacial lake plains in

the western part of the county.

ACaCi—Acer saccharum/Caulophyllum thalictroides-Circaea quadrisulcata

habitat type. The common name is Sugar maple/Blue cohosh-Enchanter’s

nightshade. The presumed potential climax overstory is dominated by sugar maple

and includes American basswood and white ash. Currently, common cover types

include any mixture of sugar maple, northern red oak, white oak, and aspen. Common

associates are red maple, basswood, white ash, black cherry, and white birch. The

dominant ground flora commonly includes grasses and sedges, sugar maple

seedlings, bigleaf aster, wild geranium, sweet cicely, lady fern, early meadow rue,

trilliums, yellow violets, enchanter’s nightshade, hog peanut, maidenhair fern, and

black snakeroot.

The moisture regime is mesic or dry-mesic, and the nutrient regime is rich. Most

tree species can exhibit excellent growth and productivity if establishment

opportunities exist and competition is controlled. Northern hardwoods demonstrate

excellent productive potential and competitive advantages. Oaks commonly occur but

require aggressive management (significant disturbance) for regeneration.

This habitat type is somewhat common on moraines, outwash plains, and glacial

lake plains in the western part of the county.

ASaI—Acer saccharum/Sanguinaria canadensis-Impatiens capensis habitat

type. The common name is Sugar maple/Bloodroot-Jewelweed. The presumed

potential climax overstory is dominated by sugar maple, red maple, white ash, green

ash, black ash, American basswood, and yellow birch. Currently, common cover types

include any mixture of aspen, red maple, red oak, white oak, bur oak, basswood, and

acid organic soil lowland (Laorg). Forested lowlands are common throughout the

county.

Recreational Development

The tables described in this section are accessible through the Soil Data

Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). The titles are:

• “Camp Areas, Picnic Areas, and Playgrounds”

• “Paths, Trails, and Golf Fairways”

In these tables, the soils of the survey area are rated according to limitations that

affect their suitability for recreational development. 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
136 Soil Survey of

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 these tables can be supplemented by other information in Web

Soil Survey, for example, interpretations for dwellings without basements, for local

roads and streets, and for septic tank absorption fields.

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

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

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

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

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

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

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

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

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

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

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

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

conductivity (Ksat), and large stones. The soil properties that affect the growth of

plants are depth to bedrock or a cemented pan, saturated hydraulic conductivity

(Ksat), 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, saturated hydraulic conductivity (Ksat),

and large stones. The soil properties that affect the growth of plants are depth to

bedrock or a cemented pan, saturated hydraulic conductivity (Ksat), 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, saturated hydraulic conductivity (Ksat), and

large stones. The soil properties that affect the growth of plants are depth to bedrock

or a cemented pan, saturated hydraulic conductivity (Ksat), 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.
Rusk County, Wisconsin 137

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.

The soils in the survey area are evaluated according to their potential for providing

habitat for various kinds of wildlife. This information can be used in planning parks,

wildlife refuges, nature study areas, and other developments for wildlife; in selecting

soils that are suitable for establishing, improving, or maintaining specific elements of

wildlife habitat; and in determining the intensity of management needed for each

element of the habitat. Specific information is available at the local office of the Natural

Resources Conservation Service.

The elements of wildlife habitat are described in the following paragraphs.

Grain and seed crops are domestic grains and seed-producing herbaceous plants.

Soil properties and features that affect the growth of grain and seed crops are depth of

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

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

considerations. Examples of grain and seed crops are corn, soybeans, wheat, oats,

and barley.

Grasses and legumes are domestic perennial grasses and herbaceous legumes.

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

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

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

considerations. Examples of grasses and legumes are bromegrass, timothy,

orchardgrass, clover, alfalfa, wheatgrass, and birdsfoot trefoil.

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

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

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

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

considerations. Examples of wild herbaceous plants are bluestems, indiangrass,

blueberry, goldenrod, lambsquarters, dandelions, blackberry, ragweed, and

nightshade.

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

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

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

Examples of these plants are oak, poplar, box elder, birch, maple, green ash, willow,

and American elm. Examples of fruit-producing shrubs that are suitable for planting on

soils rated good are Russian olive and crabapple.
138 Soil Survey of

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

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

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

cedar, and tamarack.

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

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

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

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

wild millet, rushes, sedges, bulrushes, wild rice, arrowhead, waterplantain, cattail,

prairie cordgrass, bluejoint grass, asters, and beggarticks.

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

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

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

surface stoniness, slope, and saturated hydraulic conductivity (Ksat). Examples of

shallow water areas are waterfowl feeding areas, wildlife watering developments,

beaver ponds, and other wildlife ponds.

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

Habitat for openland wildlife consists of cropland, pasture, meadows, and areas that

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

seed crops, grasses and legumes, and wild herbaceous plants. Wildlife attracted to

these areas include Hungarian partridge, ring-necked pheasant, bobwhite quail,

sharp-tailed grouse, meadowlark, field sparrow, killdeer, cottontail rabbit, and red fox.

Habitat for woodland wildlife consists of areas of deciduous and/or coniferous plants

and associated grasses, legumes, and wild herbaceous plants. Wildlife attracted to

these areas include wild turkey, ruffed grouse, thrushes, woodpeckers, owls, tree

squirrels, porcupine, raccoon, white-tailed deer, and black 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, bitterns,

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

Engineering

This section provides information for planning land uses related to urban

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

limiting features are identified. The ratings are based on observed performance of the

soils and on the data in the various soil properties reports available through the Soil

Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov).

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

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

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

apply only to that part of the soil between the surface and a depth of 5 to 7 feet.

Because of the map scale, small areas of different soils may be included within the

mapped areas of a specific soil.

The information is not site specific and does not eliminate the need for onsite

investigation of the soils or for testing and analysis by personnel experienced in the

design and construction of engineering works.

Government ordinances and regulations that restrict certain land uses or impose

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

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

and in design.

Soil properties, site features, and observed performance were considered in

determining the ratings described in this section. During the fieldwork for this soil
Rusk County, Wisconsin 139

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, saturated hydraulic conductivity (Ksat),

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 facilities; plan

detailed onsite investigations of soils and geology; locate potential sources of

construction material; plan structures for water management; 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

The tables described in this section are accessible through the Soil Data

Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). The titles are:

• “Dwellings and Small Commercial Buildings”

• “Roads and Streets, Shallow Excavations, and Lawns and Landscaping”

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

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

maintenance. The tables described in this section show the degree and kind of soil

limitations that affect dwellings with and without basements, small commercial

buildings, local roads and streets, shallow excavations, and lawns and landscaping.

The ratings in the tables are both verbal and numerical. Rating class terms indicate

the extent to which the soils are limited by all of the soil features that affect building

site development. Not limited indicates that the soil has features that are very favorable

for the specified use. Good performance and very low maintenance can be expected.

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

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

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

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

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

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

and high maintenance can be expected.

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

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

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

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

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

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

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

penetration, whichever is deeper. For dwellings with basements, the foundation is
140 Soil Survey of

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

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

The tables described in this section are accessible through the Soil Data

Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). The titles are:

• “Sewage Disposal”

• “Landfills”

These tables 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. Saturated hydraulic conductivity (Ksat), 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, saturated

hydraulic conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a

cemented pan, flooding, large stones, and content of organic matter.

Saturated hydraulic conductivity (Ksat) 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 Ksat rate of more than 14 micrometers per second 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.
142 Soil Survey of

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 saturated hydraulic conductivity (Ksat), 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, saturated hydraulic conductivity (Ksat), 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 the downward movement of water through the soil

profile 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.
Rusk County, Wisconsin 143

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

The tables described in this section are available through the Soil Data Explorer/Soil

Reports tab in Web Soil Survey (http://soils.usda.gov). The titles are:

• “Source of Sand and Gravel”

• “Source of Reclamation Material, Roadfill, and Topsoil”

Tables showing interpretations for construction materials rate the soils as potential

sources of these materials. Normal compaction, minor processing, and other standard

construction practices are assumed.

Gravel and sand are natural aggregates suitable for commercial use with a

minimum of processing. They are used in many kinds of construction. Specifications

for each use vary widely. In the table “Source of Sand and Gravel,” only the likelihood

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

specific purposes is not evaluated, nor are factors that affect excavation of the

material. The properties used to evaluate the soil as a source of sand or gravel are

gradation of grain sizes (as indicated by the Unified classification of the soil), the

thickness of suitable material, and the content of rock fragments. If the bottom layer of

the soil contains sand or gravel, the soil is considered a likely source regardless of

thickness. The assumption is that the sand or gravel layer below the depth of

observation exceeds the minimum thickness.

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

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

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

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

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

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

which the layer is a likely source.

In the report “Source of Reclamation Material, Roadfill, and Topsoil,” the rating class

terms are good, fair, and poor. The features that limit the soils as sources of these

materials are specified in the tables. The numerical ratings given after the specified

features indicate the degree to which the features limit the soils as sources of

reclamation material, roadfill, and 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.
144 Soil Survey of

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

embankments in another place. In this table, the soils are rated as a source of roadfill

for low embankments, generally less than 6 feet high and less exacting in design than

higher embankments.

The ratings are for the whole soil, from the surface to a depth of about 5 feet. It is

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

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

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

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

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

performs in place after it has been compacted and drained is determined by its

strength (as inferred from the AASHTO classification of the soil) and linear extensibility

(shrink-swell potential).

Topsoil is used to cover an area so that vegetation can be established and

maintained. The upper 40 inches of a soil is evaluated for use as topsoil. Also

evaluated is the reclamation potential of the borrow area. The ratings are based on the

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

the material; and reclamation of the borrow area. Toxic substances, soil reaction, and

the properties that are inferred from soil texture, such as available water capacity and

fertility, affect plant growth. The ease of excavating, loading, and spreading is affected

by rock fragments, slope, depth to a water table, soil texture, and thickness of suitable

material. Reclamation of the borrow area is affected by slope, depth to a water table,

rock fragments, depth to bedrock or a cemented pan, and toxic material.

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

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

of moisture and nutrients for plant growth.

Water Management

The “Ponds and Embankments” table, which is available through the Soil Data

Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov), gives information

on the soil properties and site features that affect pond reservoir areas; embankments,

dikes, and levees; and aquifer-fed excavated ponds. The ratings are both verbal and

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

the soil features that affect these uses. Not limited indicates that the soil has features

that are very favorable for the specified use. Good performance and very low

maintenance can be expected. Somewhat limited indicates that the soil has features

that are moderately favorable for the specified use. The limitations can be overcome or

minimized by special planning, design, or installation. Fair performance and moderate

maintenance can be expected. Very limited indicates that the soil has one or more

features that are unfavorable for the specified use. The limitations generally cannot be

overcome without major soil reclamation, special design, or expensive installation

procedures. Poor performance and high maintenance can be expected.

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

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

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

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

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 saturated hydraulic conductivity (Ksat) 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
Rusk County, Wisconsin 145

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 5 or 6

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.

Agricultural Waste Management

The tables described in this section are available through the Soil Data Explorer/Soil

Reports tab in Web Soil Survey (http://soils.usda.gov). The titles are:

• “Agricultural Disposal of Manure, Food-Processing Waste, and Sewage Sludge”

• “Agricultural Disposal of Wastewater by Irrigation and Overland Flow”

• “Agricultural Disposal of Wastewater by Rapid Infiltration and Slow Rate Treatment”

Soil properties are important considerations in areas where soils are used as sites

for the treatment and disposal of organic waste and wastewater. Selection of soils with

properties that favor waste management can help to prevent environmental damage.

Tables showing interpretations for agricultural waste management indicate the

degree and kind of soil limitations affecting the treatment of agricultural waste,

including municipal and food-processing wastewater and effluent from lagoons or

storage ponds. Municipal wastewater is the waste stream from a municipality. It

contains domestic waste and may contain industrial waste. It may have received

primary or secondary treatment. It is rarely untreated sewage. Food-processing

wastewater results from the preparation of fruits, vegetables, milk, cheese, and meats

for public consumption. In places it is high in content of sodium and chloride. In the

context of these tables, the effluent in lagoons and storage ponds is from facilities

used to treat or store food-processing wastewater or domestic or animal waste.

Domestic and food-processing wastewater is very dilute, and the effluent from the

facilities that treat or store it commonly is very low in content of carbonaceous and

nitrogenous material; the content of nitrogen commonly ranges from 10 to 30

milligrams per liter. The wastewater from animal waste treatment lagoons or storage

ponds, however, has much higher concentrations of these materials, mainly because

the manure has not been diluted as much as the domestic waste. The content of

nitrogen in this wastewater generally ranges from 50 to 2,000 milligrams per liter.

When wastewater is applied, checks should be made to ensure that nitrogen, heavy

metals, and salts are not added in excessive amounts.

The ratings are for waste management systems that not only dispose of and treat

organic waste or wastewater but also are beneficial to crops (application of manure
146 Soil Survey of

and food-processing waste, application of sewage sludge, and disposal of wastewater

by irrigation) and for waste management systems that are designed only for the

purpose of wastewater disposal and treatment (overland flow of wastewater, rapid

infiltration of wastewater, and slow rate treatment of wastewater).

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 agricultural waste

management. 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 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).

Application of manure and food-processing waste not only disposes of waste

material but also can improve crop production by increasing the supply of nutrients in

the soils where the material is applied. Manure is the excrement of livestock and

poultry, and food-processing waste is damaged fruit and vegetables and the peelings,

stems, leaves, pits, and soil particles removed in food preparation. The manure and

food-processing waste are either solid, slurry, or liquid. Their nitrogen content varies. A

high content of nitrogen limits the application rate. Toxic or otherwise dangerous

wastes, such as those mixed with the lye used in food processing, are not considered

in the ratings.

The ratings are based on the soil properties that affect absorption, plant growth,

microbial activity, erodibility, the rate at which the waste is applied, and the method by

which the waste is applied. The properties that affect absorption include saturated

hydraulic conductivity (Ksat), depth to a water table, ponding, the sodium adsorption

ratio, depth to bedrock or a cemented pan, and available water capacity. The

properties that affect plant growth and microbial activity include reaction, the sodium

adsorption ratio, salinity, and bulk density. The wind erodibility group, soil erosion factor

K, and slope are considered in estimating the likelihood that wind erosion or water

erosion will transport the waste material from the application site. Stones, cobbles, a

water table, ponding, and flooding can hinder the application of waste. Permanently

frozen soils are unsuitable for waste treatment.

Application of sewage sludge not only disposes of waste material but also can

improve crop production by increasing the supply of nutrients in the soils where the

material is applied. In the context of this table, sewage sludge is the residual product of

the treatment of municipal sewage. The solid component consists mainly of cell mass,

primarily bacteria cells that developed during secondary treatment and have

incorporated soluble organics into their own bodies. The sludge has small amounts of

sand, silt, and other solid debris. The content of nitrogen varies. Some sludge has

constituents that are toxic to plants or hazardous to the food chain, such as heavy

metals and exotic organic compounds, and should be analyzed chemically prior to

use.

The content of water in the sludge ranges from about 98 percent to less than 40

percent. The sludge is considered liquid if it is more than about 90 percent water,

slurry if it is about 50 to 90 percent water, and solid if it is less than about 50 percent

water.
Rusk County, Wisconsin 147

The ratings in the table are based on the soil properties that affect absorption, plant

growth, microbial activity, erodibility, the rate at which the sludge is applied, and the

method by which the sludge is applied. The properties that affect absorption, plant

growth, and microbial activity include saturated hydraulic conductivity (Ksat), depth to

a water table, ponding, the sodium adsorption ratio, depth to bedrock or a cemented

pan, available water capacity, reaction, salinity, and bulk density. The wind erodibility

group, soil erosion factor K, and slope are considered in estimating the likelihood that

wind erosion or water erosion will transport the waste material from the application

site. Stones, cobbles, a water table, ponding, and flooding can hinder the application of

sludge. Permanently frozen soils are unsuitable for waste treatment.

Disposal of wastewater by irrigation not only disposes of municipal wastewater and

wastewater from food-processing plants, lagoons, and storage ponds but also can

improve crop production by increasing the amount of water available to crops. The

ratings in the table are based on the soil properties that affect the design, construction,

management, and performance of the irrigation system. The properties that affect

design and management include the sodium adsorption ratio, depth to a water table,

ponding, available water capacity, saturated hydraulic conductivity (Ksat), slope, and

flooding. The properties that affect construction include stones, cobbles, depth to

bedrock or a cemented pan, depth to a water table, and ponding. The properties that

affect performance include depth to bedrock or a cemented pan, bulk density, the

sodium adsorption ratio, salinity, reaction, and the cation-exchange capacity, which is

used to estimate the capacity of a soil to adsorb heavy metals. Permanently frozen

soils are not suitable for disposal of wastewater by irrigation.

Overland flow of wastewater is a process in which wastewater is applied to the

upper reaches of sloped land and allowed to flow across vegetated surfaces,

sometimes called terraces, to runoff-collection ditches. The length of the run generally

is 150 to 300 feet. The application rate ranges from 2.5 to 16.0 inches per week. It

commonly exceeds the rate needed for irrigation of cropland. The wastewater leaves

solids and nutrients on the vegetated surfaces as it flows downslope in a thin film.

Most of the water reaches the collection ditch, some is lost through evapotranspiration,

and a small amount may percolate to the ground water.

The ratings in the table are based on the soil properties that affect absorption, plant

growth, microbial activity, and the design and construction of the system. Reaction and

the cation-exchange capacity affect absorption. Reaction, salinity, and the sodium

adsorption ratio affect plant growth and microbial activity. Slope, saturated hydraulic

conductivity (Ksat), depth to a water table, ponding, flooding, depth to bedrock or a

cemented pan, stones, and cobbles affect design and construction. Permanently

frozen soils are unsuitable for waste treatment.

Rapid infiltration of wastewater is a process in which wastewater applied in a level

basin at a rate of 4 to 120 inches per week percolates through the soil. The

wastewater may eventually reach the ground water. The application rate commonly

exceeds the rate needed for irrigation of cropland. Vegetation is not a necessary part

of the treatment; hence, the basins may or may not be vegetated. The thickness of the

soil material needed for proper treatment of the wastewater is more than 72 inches. As

a result, geologic and hydrologic investigation is needed to ensure proper design and

performance and to determine the risk of ground-water pollution.

The ratings in the table are based on the soil properties that affect the risk of

pollution and the design, construction, and performance of the system. Depth to a

water table, ponding, flooding, and depth to bedrock or a cemented pan affect the risk

of pollution and the design and construction of the system. Slope, stones, and cobbles

also affect design and construction. Saturated hydraulic conductivity (Ksat) and

reaction affect performance. Permanently frozen soils are unsuitable for waste

treatment.
148 Soil Survey of

Slow rate treatment of wastewater is a process in which wastewater is applied to

land at a rate normally between 0.5 inch and 4.0 inches per week. The application rate

commonly exceeds the rate needed for irrigation of cropland. The applied wastewater

is treated as it moves through the soil. Much of the treated water may percolate to the

ground water, and some enters the atmosphere through evapotranspiration. The

applied water generally is not allowed to run off the surface. Waterlogging is prevented

either through control of the application rate or through the use of tile drains, or both.

The ratings in the table are based on the soil properties that affect absorption, plant

growth, microbial activity, erodibility, and the application of waste. The properties that

affect absorption include the sodium adsorption ratio, depth to a water table, ponding,

available water capacity, saturated hydraulic conductivity (Ksat), depth to bedrock or a

cemented pan, reaction, the cation-exchange capacity, and slope. Reaction, the

sodium adsorption ratio, salinity, and bulk density affect plant growth and microbial

activity. The wind erodibility group, soil erosion factor K, and slope are considered in

estimating the likelihood of wind erosion or water erosion. Stones, cobbles, a water

table, ponding, and flooding can hinder the application of waste. Permanently frozen

soils are unsuitable for waste treatment.

Data relating to soil properties are collected during the course of the soil survey.

Soil properties are determined by field examination of the soils and by laboratory

index testing of some benchmark soils. Established standard procedures are followed.

During the survey, many shallow borings are made and examined to identify and

classify the soils and to delineate them on the soil maps. Samples are taken from

some typical profiles and tested in the laboratory to determine 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

properties, physical and chemical properties, and pertinent soil and water features.

Engineering Properties

The “Engineering Properties” table described in this section is available through the

Soil Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). It gives

the engineering classifications and the range of engineering properties for the layers of

each soil in the survey area.

Depth to the upper and lower boundaries of each layer is indicated.

Texture is given in the standard terms used by the U.S. Department of Agriculture.

These terms are defined according to percentages of sand, silt, and clay in the fraction

of the soil that is less than 2 millimeters in diameter. “Loam,” for example, is soil that is

7 to 27 percent clay, 28 to 50 percent silt, and less than 52 percent sand. If the content

of particles coarser than sand is 15 percent or more, an appropriate modifier is added,

for example, “gravelly.” Textural terms are defined in the Glossary.

Classification of the soils is determined according to the Unified soil classification

system (ASTM, 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.

Soil Properties
160 Soil Survey of

If laboratory data are available, the A-1, A-2, and A-7 groups are further classified

as A-1-a, A-1-b, A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additional

refinement, the suitability of a soil as subgrade material can be indicated by a group

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

or higher for the poorest.

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

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

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

weight percentage.

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

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

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

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

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

field.

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

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

from nearby areas and on field examination.

Physical Soil Properties

The “Physical Soil Properties” table described in this section is available through the

Soil Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). It shows

estimates of some physical characteristics and features that affect soil behavior. These

estimates are given for the layers of each soil in the survey area. The estimates are

based on field observations and on test data for these and similar soils.

Depth to the upper and lower boundaries of each layer is indicated.

Particle size is the effective diameter of a soil particle as measured by

sedimentation, sieving, or micrometric methods. Particle sizes are expressed as

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

and clay, ranging from the larger to the smaller.

Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter to

2 millimeters in diameter. In the table, the estimated sand content of each soil layer is

given as a percentage, by weight, of the soil material that is less than 2 millimeters in

diameter.

Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05

millimeter in diameter. In the table, the estimated silt content of each soil layer is given

as a percentage, by weight, of the soil material that is less than 2 millimeters in

diameter.

Clay as a soil separate consists of mineral soil particles that are less than 0.002

millimeter in diameter. In the table, the estimated clay content of each soil layer is

given as a percentage, by weight, of the soil material that is less than 2 millimeters in

diameter.

The content of sand, silt, and clay affects the physical behavior of a soil. Particle

size is important for engineering and agronomic interpretations, for determination of

soil hydrologic qualities, and for soil classification.

The amount and kind of clay affect the fertility and physical condition of the soil and

the ability of the soil to adsorb cations and to retain moisture. They influence shrinkswell potential, saturated hydraulic conductivity (Ksat), 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
Rusk County, Wisconsin 161

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 linear extensibility,

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.

Saturated hydraulic conductivity (Ksat) refers to the ability of a soil to transmit water

or air. The estimates in the table indicate the rate of water movement, in micrometers

per second, when the soil is saturated. They are based on soil characteristics

observed in the field, particularly structure, porosity, and texture. Saturated hydraulic

conductivity (Ksat) 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.

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

decomposition. In the table, 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 the table 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

saturated hydraulic conductivity (Ksat). 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.
162 Soil Survey of

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,” which is

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

Internet.

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 Soil Properties

The “Chemical Soil Properties” table described in this section is available through

the Soil Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). It

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.

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

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

for soils that have pH of less than 5.5.

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

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

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

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

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

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

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

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

Gypsum is expressed as a percent, by weight, of hydrated calcium sulfates in the

fraction of the soil less than 20 millimeters in size. Gypsum is partially soluble in water.

Soils that have a high content of gypsum may collapse if the gypsum is removed by

percolating water.

Salinity is a measure of soluble salts in the soil at saturation. It is expressed as the

electrical conductivity of the saturation extract, in millimhos per centimeter at 25

degrees C. Estimates are based on field and laboratory measurements at

representative sites of nonirrigated soils. The salinity of irrigated soils is affected by the

quality of the irrigation water and by the frequency of water application. Hence, the

salinity of soils in individual fields can differ greatly from the value given in the table.

Salinity affects the suitability of a soil for crop production, the stability of soil if used as

construction material, and the potential of the soil to corrode metal and concrete.

Sodium adsorption ratio (SAR) is a measure of the amount of sodium (Na) relative

to calcium (Ca) and magnesium (Mg) in the water extract from saturated soil paste. It
Rusk County, Wisconsin 163

is the ratio of the Na concentration divided by the square root of one-half of the Ca +

Mg concentration. Soils that have SAR values of 13 or more may be characterized by

an increased dispersion of organic matter and clay particles, reduced saturated

hydraulic conductivity (Ksat) and aeration, and a general degradation of soil structure.

Water Features

The “Water Features” table described in this section is available through the Soil

Data Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). It 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.

Surface runoff refers to the loss of water from an area by flow over the land surface.

Surface runoff classes are based on slope, climate, and vegetative cover. It is

assumed that the surface of the soil is bare and that the retention of surface water

resulting from irregularities in the ground surface is minimal. The classes are

negligible, very low, low, medium, high, and very high.

The months in the table indicate the portion of the year in which the feature is most

likely to be a concern.

Water table refers to a saturated zone in the soil. The table indicates, by month,

depth to the top (upper limit) and base (lower limit) of the saturated zone in most

years. Estimates of the upper and lower limits are based mainly on observations of the

water table at selected sites and on evidence of a saturated zone, namely grayish

colors or mottles (redoximorphic features) in the soil. A saturated zone that lasts for

less than a month is not considered a water table.

Ponding is standing water in a closed depression. Unless a drainage system is

installed, the water is removed only by percolation, transpiration, or evaporation. The

table indicates surface water depth and the duration and frequency of ponding.

Duration is expressed as very brief if less than 2 days, brief if 2 to 7 days, long if 7 to

30 days, and very long if more than 30 days. Frequency is expressed as none, rare,

occasional, and frequent. None means that ponding is not probable; rare that it is

unlikely but possible under unusual weather conditions (the chance of ponding is
164 Soil Survey of

nearly 0 percent to 5 percent in any year); occasional that it occurs, on the average,

once or less in 2 years (the chance of ponding is 5 to 50 percent in any year); and

frequent that it occurs, on the average, more than once in 2 years (the chance of

ponding is more than 50 percent in any year).

Flooding is the temporary inundation of an area caused by overflowing streams, by

runoff from adjacent slopes, or by tides. Water standing for short periods after rainfall

or snowmelt is not considered flooding, and water standing in swamps and marshes is

considered ponding rather than flooding.

Duration and frequency are estimated. Duration is expressed as extremely brief if

0.1 hour to 4 hours, very brief if 4 hours to 2 days, brief if 2 to 7 days, long if 7 to 30

days, and very long if more than 30 days. Frequency is expressed as none, very rare,

rare, occasional, frequent, and very frequent. None means that flooding is not

probable; very rare that it is very unlikely but possible under extremely unusual

weather conditions (the chance of flooding is less than 1 percent in any year); rare that

it is unlikely but possible under unusual weather conditions (the chance of flooding is 1

to 5 percent in any year); occasional that it occurs infrequently under normal weather

conditions (the chance of flooding is 5 to 50 percent in any year); frequent that it is

likely to occur often under normal weather conditions (the chance of flooding is more

than 50 percent in any year but is less than 50 percent in all months in any year); and

very frequent that it is likely to occur very often under normal weather conditions (the

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

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

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

with increasing depth; and little or no horizon development.

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

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

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

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

Soil Features

The “Soil Features” table described in this section is available through the Soil Data

Explorer/Soil Reports tab in Web Soil Survey (http://soils.usda.gov). It 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 and thickness of the restrictive layer, both of

which significantly affect the ease of excavation. Depth to top is the vertical distance

from the soil surface to the upper boundary of the restrictive layer.

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, saturated

hydraulic conductivity (Ksat), content of organic matter, and depth to the water table

are the most important factors considered in evaluating the potential for frost action. It
Rusk County, Wisconsin 165

is assumed that the soil is not insulated by vegetation or snow and is not artificially

drained. Silty and highly structured, clayey soils that have a high water table in winter

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

are the least susceptible. Frost heave and low soil strength during thawing cause

damage to pavements and other rigid structures.

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

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

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

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

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

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

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

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

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

layer.

For uncoated steel, the risk of corrosion, expressed as low, moderate, or high, is

based on soil drainage class, total acidity, electrical resistivity near field capacity, and

electrical conductivity of the saturation extract.

For concrete, the risk of corrosion also is expressed as low, moderate, or high. It is

based on soil texture, acidity, and amount of sulfates in the saturation extract.

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.

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.”

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

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

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

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

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

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

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

a combination of erosion and deposition.

Dry spot (map symbol). A small area of moderately well drained to excessively

drained soil within a poorly drained or very poorly drained area of mineral soil, or a

somewhat poorly drained to excessively drained soil within a map unit consisting

mainly of organic soil. Each symbol represents one area or several closely

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

the litter on the surface to underlying pure humus.

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.

Rusk County, Wisconsin 177

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.

Ice-walled lake plain. A relict surface marking the floor of an extinct lake basin that

was formed on solid ground and surrounded by stagnant ice in a stable or

unstable superglacial environment on stagnation moraines. As the ice melted, the

lake plain became perched above the adjacent landscape. The lake plain is well

sorted, generally fine textured, stratified deposits.

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

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.
178 Soil Survey of

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

receives ground-water discharge or long, continued contributions from melting

snow or other surface and shallow subsurface sources.

determine the shrink-swell potential of soils. It is an expression of the volume

change between the water content of the clod at 1

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

10kPa tension) and oven dryness. Volume change is influenced by the amount and

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

vegetation. This practice increases the vigor and reproduction capacity of the key

plants and promotes the accumulation of litter and mulch necessary to conserve

soil and water.

Rangeland. Land on which the potential natural vegetation is predominantly grasses,

grasslike plants, forbs, or shrubs suitable for grazing or browsing. It includes

natural grasslands, savannas, many wetlands, some deserts, tundras, and areas

that support certain forb and shrub communities.

Redoximorphic concentrations. See Redoximorphic features.

Redoximorphic depletions. See Redoximorphic features.

Redoximorphic features. Redoximorphic features are associated with wetness and

result from alternating periods of reduction and oxidation of iron and manganese

compounds in the soil. Reduction occurs during saturation with water, and

oxidation occurs when the soil is not saturated. Characteristic color patterns are

created by these processes. The reduced iron and manganese ions may be

removed from a soil if vertical or lateral fluxes of water occur, in which case there

is no iron or manganese precipitation in that soil. Wherever the iron and

manganese are oxidized and precipitated, they form either soft masses or hard

concretions or nodules. Movement of iron and manganese as a result of

redoximorphic processes in a soil may result in redoximorphic features that are

defined as follows:

1. Redoximorphic concentrations.—These are zones of apparent accumulation of

iron-manganese oxides, including:

A. Nodules and concretions, which are cemented bodies that can be

removed from the soil intact. Concretions are distinguished from nodules on the

basis of internal organization. A concretion typically has concentric layers that

are visible to the naked eye. Nodules do not have visible organized internal

structure; and

B. Masses, which are noncemented concentrations of substances within

the soil matrix; and

C. Pore linings, i.e., zones of accumulation along pores that may be either

coatings on pore surfaces or impregnations from the matrix adjacent to the

pores.

2. Redoximorphic depletions.—These are zones of low chroma (chromas less

than those in the matrix) where either iron-manganese oxides alone or both

iron-manganese oxides and clay have been stripped out, including:

A. Iron depletions, i.e., zones that contain low amounts of iron and

manganese oxides but have a clay content similar to that of the adjacent matrix;

and

B. Clay depletions, i.e., zones that contain low amounts of iron, manganese,

and clay (often referred to as silt coatings or skeletans).

3. Reduced matrix.—This is a soil matrix that has low chroma in situ but

undergoes a change in hue or chroma within 30 minutes after the soil material

has been exposed to air.

requirements for the major land uses in the survey area.

Sinkhole. A closed, circular or elliptical depression, commonly funnel shaped,

characterized by subsurface drainage and formed either by dissolution of the

rock or by collapse of underlying caves. Typically less than 3 acres.

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.

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/

Burnished peds and sorting of rounded or subrounded pebbles or cobbles

distinguish these materials from unsorted colluvial deposits.

resulting from human activity. The areas are typically less than 3 acres.

Stone line. In a vertical cross section, a line formed by scattered fragments or a

discrete layer of angular and subangular rock fragments (commonly a gravel- or

cobble-sized lag concentration) that formerly was draped across a topographic

surface and was later buried by additional sediments. A stone line generally caps

material that was subject to weathering, soil formation, and erosion before burial.

Many stone lines seem to be buried erosion pavements, originally formed by sheet

and rill erosion across the land surface.

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

tops), blocky (angular or subangular), and granular. Structureless soils are either

single grained (each grain by itself, as in dune sand) or massive (the particles

adhering without any regular cleavage, as in many hardpans).

Stubble mulch. Stubble or other crop residue left on the soil or partly worked into the

typically has the form of a massive arcuate or concentric ridge, or complex of

ridges, and is underlain by till and other types of drift.

Terrace (conservation). An embankment, or ridge, constructed across sloping soils on

the contour or at a slight angle to the contour. The terrace intercepts surface runoff

so that water soaks into the soil or flows slowly to a prepared outlet. A terrace in a

field generally is built so that the field can be farmed. A terrace intended mainly for

drainage has a deep channel that is maintained in permanent sod.

Terrace (geomorphology). A steplike surface, bordering a valley floor or shoreline, that

represents the former position of a flood plain, lake, or seashore. The term is

usually applied both to the relatively flat summit surface (tread) that was cut or

built by stream or wave action and to the steeper descending slope (scarp or riser)

that has graded to a lower base level of erosion.

Terracettes. Small, irregular steplike forms on steep hillslopes, especially in pasture,

formed by creep or erosion of surficial materials that may be induced or enhanced

by trampling of livestock, such as sheep or cattle.

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.”

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.

hillslope continuum.

Valley fill. The unconsolidated sediment deposited by any agent (water, wind, ice, or

mass wasting) so as to fill or partly fill a valley.

still water within a year. Specifically, a thin pair of graded glaciolacustrine layers

seasonally deposited, usually by meltwater streams, in a glacial lake or other body

of still water in front of a glacier.

surface is covered by rock fragments more than 10 inches in diameter within an

area that does not have rock fragments on the surface. The area is typically less

than 3 acres.

Water bars. Smooth, shallow ditches or depressional areas that are excavated at an

angle across a sloping road. They are used to reduce the downward velocity of

water and divert it off and away from the road surface. Water bars can easily be

driven over if constructed properly.

Weathering. All physical disintegration, chemical decomposition, and biologically

induced changes in rocks or other deposits at or near the earth’s surface by

atmospheric or biologic agents or by circulating surface waters but involving

essentially no transport of the altered material.

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.
