NRCS Accessibility Statement
General Soil Map

The general soil map, which is a color map, shows the survey area divided into groups of associated soils called

general soil map units. This map is useful in planning the use and management of large areas.

To find information about your area of interest, locate that area on the map, identify the name of the map unit in the

area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of

the soils in your area.

Detailed Soil Maps

The detailed soil maps can be useful in planning the use and

management of small areas.

To find information about your area

of interest, locate that area on the

Index to Map Sheets. Note the

number of the map sheet and turn

to that sheet.

Locate your area of interest on

the map sheet. Note the map unit

symbols that are in that area. Turn

to the Contents, which lists the

map units by symbol and name

and shows the page where each

map unit is described.

The Contents shows which table

has data on a specific land use for

each detailed soil map unit. Also

see the Contents for sections of

this publication that may address

your specific needs.

Additional information about the Nation’s natural resources is available on the

Natural Resources Conservation Service homepage on the World Wide Web. The

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

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

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

Natural Resources Conservation Service (formerly the Soil Conservation Service) has

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

Major fieldwork for this soil survey was completed in 2000. Soil names and

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

publication refer to conditions in the survey area in 2000. This survey was made

cooperatively by the Natural Resources Conservation Service; the Iowa Agriculture and

Home Economics Experiment Station and the Cooperative Extension Service, Iowa

State University; the Division of Soil Conservation, Iowa Department of Agriculture and

Land Stewardship; and the Woodbury County Board of Supervisors. The survey is part

of the technical assistance furnished to the Woodbury County Soil and Water

Conservation District. Funds appropriated by Woodbury County were used to defray

part of the cost of the survey.

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.

Cover: Upper left—An area of Hamburg silt loam, 40 to 75 percent slopes, in the Ida-Napier-Monona

association. The soils in this association still support the native vegetation. This area is a unique geological

feature of the loess bluffs along the Missouri River Valley. Upper right—An area of Galva silty clay loam, 2

to 5 percent slopes, in the Galva association in the northwestern part of the county. The soils in this

association are used intensively for row crops. Lower left—Calcareous overwash in an area of the LutonTieville association. The recent deposition is from the adjacent uplands. Lower right—Terraces and contour

farming in an area of the Monona-Ida-Judson association. Controlling erosion is important for maintaining

productivity in areas of this association.

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

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

highlights soil limitations, improvements needed to overcome the limitations, and the

impact of selected land uses on the environment.

This soil survey is designed for many different users. Farmers, foresters, and

agronomists can use it to evaluate the potential of the soil and the management needed

for maximum food and fiber production. Planners, community officials, engineers,

developers, builders, and home buyers can use the survey to plan land use, select sites

for construction, and identify special practices needed to ensure proper performance.

Conservationists, teachers, students, and specialists in recreation, wildlife

management, waste disposal, and pollution control can use the survey to help them

understand, protect, and enhance the environment.

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

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

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

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

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

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

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

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

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

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

poorly suited to basements or underground installations.

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

survey. Broad areas of soils are shown on the general soil map. The location of each

soil is shown on the detailed soil maps. Each soil in the survey area is described, and

information on specific uses is given. Help in using this publication and additional

information are available at the local office of the Natural Resources Conservation

Service or the Cooperative Extension Service.

Foreword

1

WOODBURY COUNTY is in west-central Iowa (fig. 1). It

has an area of 561,500 acres, or 877 square miles. It

is bounded on the west by the Missouri River, on the

east by Ida County, on the north by Plymouth County,

and on the south by Monona County. Sioux City is the

county seat.

This soil survey updates the survey of Woodbury

County published in 1972 (Worster and others, 1972).

It provides additional information and has larger maps,

which show the soils in greater detail.

General Nature of the Survey Area

This section provides general information about the

survey area. It describes history; natural resources,

transportation facilities, and recreation; physiography;

and climate.

History

The first historical report of the survey area was

made by the Lewis and Clark expedition in 1804, 48

years before the first European settlers arrived

(Warner and Company, 1891). Lewis and Clark

navigated up the Missouri River past the area that is

now Woodbury County. One man, Sergeant Charles

Floyd, died on the expedition and was buried at the top

of the loess bluffs, overlooking the presentday site of

Sioux City.

The Native people who frequented the area at the

time were the Oto, Omaha, Missouri, and Sioux. The

Missouri River was a major route of commerce and

travel used by Native, trader, and settler alike.

Woodbury County was established in 1852 by an

act of the Iowa General Assembly. Two years later, in

the spring of 1854, a Harrison County court took steps

toward the organization of Woodbury County. County

boundaries were fixed in 1865.

By the time the county was established, the

population had grown from 3 to 950 settlers in only a

few years. Over the next 30 years, the population grew

to 12,147. The population of the county reached a

peak in 1940, when it was recorded as 18,238 (USDA,

1997).

The first non-Native settlers in Woodbury County

are believed to be William Thompson and his brother

Charles (Warner and Company, 1891). The

Thompsons spent the winter of 1848 in the area. The

first settler of Sioux City was Joseph Leonais in 1852.

Leonais lived where 2nd Street is now located. In

1853, the town of Floyd’s Bluff was established and

was chosen as the county seat (Warner and

Company, 1891).

Early enterprises in the county were trapping,

hunting, and trading with the Indians. As settlement

increased, agriculture quickly became the

predominant occupation in the county.

The first railway came to Woodbury County in 1868.

Within 20 years, eight railways were operating in the

county, and the area became the railroad center of the

Midwest. The railroad greatly improved transportation

and access to markets, which led to the settlement

and development of the county.

Natural Resources, Transportation

Facilities, and Recreation

The most valuable natural resources in Woodbury

County are the soils on agricultural lands. Bottom land

in the Missouri River Valley is generally ideal for the

production of row crops. The uplands in the county (in

areas where the slope is not too severe) are excellent

for row crops, forage, and pasture.

Sand and gravel occur in many parts of the county,

typically in association with major streams and rivers.

Wildlife is abundant in Woodbury County. Deer,

pheasant, turkey, quail, and small furbearers are

common because of the good habitat and food supply.

Fish are plentiful in the rivers, ditches, and

impoundments throughout the county. There is

sufficient ground water in the bottom-land areas along

the Missouri River for irrigation, which is used in the

seed production industry.

A good farm-to-market road system is supported

throughout the county. Federal, State, and county

highways provide good access to all parts of the

county. Interstate 29 runs north and south through

Salix, Sloan, and Sergeant Bluff and into Sioux City.

State Highway 20 runs east and west from Sioux City

through Lawton, Moville, and Correctionville. State

Highway 31 runs north and south from Smithland,

through Oto and Anthon, and on to Correctionville.

State Highway 141 runs east and west from Sloan

through Hornick and Smithland. Paved county roads

and other gravel roads increase the accessibility of the

communities in the county.

Railroad service is provided to Sloan, Salix,

Sergeant Bluff, and Sioux City. Truck service is

available to all communities. Bus service is available in

Sioux City. Small aircraft and commercial flights are

flown out of Sioux City. There are barge facilities on

the Missouri River within the county.

Recreational opportunities in Woodbury County are

many. State and county parks provide facilities for

camping, fishing, boating, hunting, picnicking, hiking,

and sightseeing. Many of the towns in the county have

well furnished city parks.

Southwood County Park provides boating, fishing,

swimming, camping, and picnic opportunities. Stone

State Park and Little Sioux County Park offer camping,

hiking, and picnic facilities.

The Loess Ridge Nature Center is devoted to

Iowa’s loess hills. It offers hiking and exhibits and a

scenic view of the Missouri River flood plain from atop

the loess bluffs.

The Loess Hills Scenic Byway is a system of scenic

routes through the beautiful and unique loess hills of

Woodbury County. The Loess Hills Scenic Byway links

the counties adjacent to the Missouri River.

Physiography

The Missouri River Valley in Woodbury County

consists of three distinct geomorphic regions. These

are the Bar Area, Young Bottom Land, and Old Bottom

Land (fig. 2).

The Bar Area is in the area adjacent to the Missouri

River. It is nearly continuous from north to south in

Woodbury County. It includes the area thought to have

been occupied by the Missouri River within about the

last 100 years. This area was frequently flooded with 8

to 10 feet of water before the construction of dams on

the Missouri River.

The Army Corps of Engineers built dams upstream

on the Missouri River in South Dakota and North

Dakota to control downstream flooding. These dams

were completed in 1955. Since that time, the only

remaining frequently flooded areas are chutes, low

swales, and low areas next to the Missouri River.

Because of these dams, the Bar Area has not been

flooded since 1952 and the frequency of flooding in

the area is now estimated as occasional.

There are no farmsteads in the Bar Area, but a few

cabins have been built in recent years for recreational

purposes. Some of the soils in the Bar Area are the

occasionally flooded Albaton and Percival soils and

Morconick and Scroll soils.

The Young Bottom Land is in the area between the

Bar Area and the Old Bottom Land. The Missouri River

occupied channels in this area within the past 100 to

300 years. As the river meandered, meander loops

and channels were abandoned. Some of the loops and
Woodbury County, Iowa 3

channels were partly filled by deposition during later

flooding. Most of the Young Bottom Land was covered

with floodwater during the flood of 1952. Some areas

of Blake, Haynie, and Modale soils were not flooded

because they are in the highest elevations. The

frequency of flooding in the Young Bottom Land area is

now estimated as rare because of the dams on the

Missouri River.

Many of the same soils are mapped in both the Bar

Area and the Young Bottom Land region. These soils

are identified on the soil maps with different map unit

symbols because of the differences in flooding

frequency in the two regions. Also, the soil map units

in the Young Bottom Land region are generally

somewhat less stratified than the corresponding soil

map units in the Bar Area. Some of the soils in the

Young Bottom Land region are Blend soils and the

rarely flooded Albaton and Sarpy soils.

The Old Bottom Land is in the area between the

rarely flooded Young Bottom Land and the loess hills in

the uplands. The Old Bottom Land region has fewer

surface features than either the Bar Area or the Young

Bottom Land, mainly because it does not have

meander scars and oxbows left behind from the

meandering Missouri River.

The Missouri River channel has not occupied the

Old Bottom Land region for a very long period of time;

therefore, the soils are much older (in geologic time)

than those in the Young Bottom Land region and in the

Bar Area. Typical soils closest to the river in the Old

Bottom Land region are the rarely flooded Blencoe

and Lakeport soils.

Floodwaters have not crested this natural levee and

allowed the Missouri River to reoccupy this area for

hundreds to perhaps thousands of years. Therefore,

the soils are more developed because they are much

older than those in the Young Bottom Land region and

in the Bar Area. If flooding occurs in the Old Bottom

Land region, it is mainly from the flooded tributary

rivers and streams.

Poorly drained, clayey soils are dominant in the part

of the Old Bottom Land that is farther from the river

channel. Examples are the rarely flooded Luton and

Woodbury soils.

Much of the Old Bottom Land is at a lower elevation

than the Young Bottom Land but has been flooded less

frequently. At the conjunction of the Young Bottom

Land and the Old Bottom Land, the Young Bottom

Land is cut deeper into the Missouri River Valley and

leaves behind an area that acts as a natural levee that

is higher in elevation than the remaining areas of the

Young Bottom Land or Old Bottom Land regions. Keg

and Salix soils are examples of soils mapped on this

natural levee.

Climate

Table 1 gives data on temperature and precipitation

for the survey area as recorded at Sioux City in the

period 1971 to 2000. Table 2 shows probable dates of

the first freeze in fall and the last freeze in spring.

Table 3 provides data on the length of the growing

season.

In winter, the average temperature is 22.1 degrees

F and the average daily minimum temperature is 12.8

degrees. The lowest temperature on record, which

occurred at Sioux City on January 19, 1970, was -26

degrees. In summer, the average temperature is 72.7

degrees and the average daily maximum temperature

is 83.8 degrees. The highest temperature, which

4 Soil Survey of

occurred at Sioux City on July 12, 1995, was 108

degrees.

Growing degree days are shown in table 1. They

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

growing degree days accumulate by the amount that

the average temperature each day exceeds a base

temperature (50 degrees F). The normal monthly

accumulation is used to schedule single or successive

plantings of a crop between the last freeze in spring

and the first freeze in fall.

The average annual total precipitation is 25.99

inches. Of this total, 15.98 inches, or about 61 percent,

usually falls in May through September. The growing

season for most crops falls within this period. The

heaviest 1-day rainfall during the period of record was

5.5 inches at Sioux City on July 17, 1972.

Thunderstorms occur on about 44 days each year,

and most occur between May and August.

The average seasonal snowfall is 30.8 inches. The

greatest snow depth at any one time was 28 inches

recorded on March 13, 1962. On average, 59 days per

year have at least 1 inch of snow on the ground. The

heaviest 1-day snowfall on record was 17.4 inches

recorded on January 22, 1982.

The average relative humidity in midafternoon is

about 45 percent in April and May and 70 percent in

December and January. Humidity is higher at night,

and the average at dawn is about 80 percent for much

of the year, except in midsummer, when it is nearly 90

percent. The sun shines 70 percent of the time

possible in summer and 55 percent in winter. The

prevailing wind is from the northwest from November

to April and from the south for the rest of the year.

Average windspeed is highest, around 13 miles per

hour, in April.

How This Survey Was Made

This soil survey was a pilot project designed to

obtain statistically valid estimates for the composition

of map units in Woodbury County, Iowa. The specific

objective of this project was to provide better

information about the distribution of soil characteristics

for every map unit in the survey area (Abbot and

others, 1999).

In order to obtain statistically valid estimates of the

map units, a multiphase sample design was created.

Global Positioning System and Geographical

Information System technologies were used to

develop a method for selecting random sample points

throughout the county. This study was based on a

realistic sample size and with the advantage of

existing knowledge of the soils and their

characteristics. This type of statistical sampling was

applied to all parts of the county consisting of different

soils and classifications (Abbot and others, 1999).

A major contribution of this approach is that data

collected under this design can be further used for a

broader suite of statistical analyses than in the more

traditional soil update. For instance, the data can be

used to obtain alternative estimates of representative

values and ranges that are statistically defensible. In

addition, other measures, such as means, percentiles,

and parametric distributions, can be generated along

with estimated standard errors. Furthermore, the data

resulting from this approach can support

geographically linked modeling efforts (Abbot and

others, 1999).

This survey was made to provide updated

information about the soils and miscellaneous areas in

the survey area, which is in Major Land Resource

Area 107. Major land resource areas (MLRAs) are

geographically associated land resource units that

share a common land use, elevation, topography,

climate, water, soils, and vegetation (USDA, 1981).

Woodbury County is a subset of MLRA 107. Map unit

design is based on documentation of the occurrence

of the soils throughout the MLRA.

Besides statistical information, the information in

this survey includes a description of the soils and

miscellaneous areas and their location and a

discussion of their properties and the subsequent

effects on suitability, limitations, and management for

specified uses. Soil scientists observed the steepness,

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

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

kinds of bedrock. They dug many holes to study the

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

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

down into the unconsolidated material in which the soil

formed. The unconsolidated material is devoid of roots

and other living organisms and has not been changed

by other biological activity.

The soils and miscellaneous areas in the survey

area are in an orderly pattern that is related to the

geology, landforms, relief, climate, and natural

vegetation of the area. Each kind of soil and

miscellaneous area is associated with a particular kind

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
Woodbury County, Iowa 5

into one another as their characteristics gradually

change. To construct an accurate map, however, soil

scientists must determine the boundaries between the

soils. They can observe only a limited number of soil

profiles. Nevertheless, these observations,

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

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

determine the boundaries.

Soil scientists recorded the characteristics of the

soil profiles that they observed from statistical points

selected throughout the county, from other borings,

and from soil characterization pits (Abbot and others,

1999). 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 water table within

certain depths in most years, but they cannot predict

that the water table will always be at a specific level in

the soil on a specific date.

After soil scientists located and identified the

significant natural bodies of soil in the survey area,

they drew the boundaries of these bodies on aerial

photographs and identified each as a specific map

unit. Aerial photographs show trees, buildings, fields,

roads, and rivers, all of which help in locating

boundaries accurately.

The descriptions, names, and delineations of the

soils in this survey area may not fully agree with those

of the soils in adjacent survey areas. Differences are

the result of an improved knowledge of soils,

modifications in series concepts, or variations in the

intensity of mapping or in the extent of the soils in the

survey areas.

7

The general soil map in this publication shows

broad areas that have a distinctive pattern of soils,

relief, and drainage. These broad areas are called

associations. Each association on the general soil

map is a unique natural landscape. Typically, it

consists of one or more major soils or miscellaneous

areas and some minor soils or miscellaneous areas. It

is named for the major soils or miscellaneous areas.

The soils or miscellaneous areas making up one

association can occur in another but in a different

pattern.

The general soil map can be used to compare the

suitability of large areas for general land uses. Areas

of suitable soils or miscellaneous areas can be

identified on the map. Likewise, areas that are not

suitable can be identified.

Because of its small scale, the map is not suitable

for planning the management of a farm or field or for

selecting a site for a road or building or other structure.

The soils in any one association differ from place to

place in slope, depth, drainage, and other

characteristics that affect management.

The map units delineated on the detailed soil maps

in this survey represent the soils or miscellaneous

areas in the survey area. The map unit descriptions in

this section, along with the maps, can be used to

determine the suitability and potential of a unit for

specific uses. They also can be used to plan the

management needed for those uses.

A map unit delineation on a soil map represents an

area dominated by one or more major kinds of soil or

miscellaneous areas. A map unit is identified and

named according to the taxonomic classification of the

dominant soils. Within a taxonomic class there are

precisely defined limits for the properties of the soils.

On the landscape, however, the soils are natural

phenomena, and they have the characteristic

variability of all natural phenomena. Thus, the range of

some observed properties may extend beyond the

limits defined for a taxonomic class. Areas of soils of a

single taxonomic class rarely, if ever, can be mapped

without including areas of other taxonomic classes.

Consequently, every map unit is made up of the soils

or miscellaneous areas for which it is named and

some minor components that belong to taxonomic

classes other than those of the major soils.

Most minor soils have properties similar to those of

the dominant soil or soils in the map unit, and thus

they do not affect use and management. These are

called noncontrasting, or similar, components. They

may or may not be mentioned in a particular map unit

description. Other minor components, however, have

properties and behavioral characteristics divergent

enough to affect use or to require different

management. These are called contrasting, or

dissimilar, components. They generally are in small

areas and could not be mapped separately because of

the scale used. Some small areas of strongly

contrasting soils or miscellaneous areas are identified

by a special symbol on the maps. The contrasting

components are mentioned in the map unit

descriptions. A few areas of minor components may

not have been observed, and consequently they are

not mentioned in the descriptions, especially where

the pattern was so complex that it was impractical to

make enough observations to identify all the soils and

miscellaneous areas on the landscape.

The presence of minor components in a map unit in

no way diminishes the usefulness or accuracy of the

data. The objective of mapping is not to delineate pure

taxonomic classes but rather to separate the

landscape into landforms or landform segments that

have similar use and management requirements. The

delineation of such segments on the map provides

sufficient information for the development of resource

plans. If intensive use of small areas is planned,

however, onsite investigation is needed to define and

locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name

in the map unit descriptions. Each description includes

general facts about the unit and gives the principal

hazards and limitations to be considered in planning

for specific uses.

Soils that have profiles that are almost alike make

up a soil series. Except for differences in texture of the

surface layer, all the soils of a series have major

horizons that are similar in composition, thickness,

and arrangement.

Soils of one series can differ in texture of the

surface layer, slope, stoniness, salinity, degree of

erosion, and other characteristics that affect their use.

On the basis of such differences, a soil series is

divided into soil phases. Most of the areas shown on

the detailed soil maps are phases of soil series. The

name of a soil phase commonly indicates a feature

that affects use or management. For example, Monona

silt loam, 9 to 14 percent slopes, severely eroded, is a

phase of the Monona series.

Some map units are made up of two or more major

soils or miscellaneous areas. These map units are

called complexes. A complex consists of two or more

soils or miscellaneous areas in such an intricate

pattern or in such small areas that they cannot be

shown separately on the maps. The pattern and

proportion of the soils or miscellaneous areas are

somewhat similar in all areas. Napier-Castana silt

loams, 9 to 20 percent slopes, is an example.

This survey includes miscellaneous areas. Such

areas have little or no soil material and support little or

no vegetation. Map unit 5010 (Pits, sand and gravel) is

an example.

of each map unit. Other tables give properties of the

soils and the limitations, capabilities, and potentials for

many uses. The Glossary defines many of the terms

used in describing the soils or miscellaneous areas.

This soil survey is an inventory and evaluation of

the soils in the survey area. It can be used to adjust

land uses to the limitations and potentials of natural

resources and the environment. Also, it can help to

prevent soil-related failures in land uses.

In preparing a soil survey, soil scientists,

conservationists, engineers, and others collect

extensive field data about the nature and behavioral

characteristics of the soils. They collect data on

erosion, droughtiness, flooding, and other factors that

affect various soil uses and management. Field

experience and collected data on soil properties and

performance are used as a basis in predicting soil

behavior.

Information in this section can be used to plan the

use and management of soils for crops and pasture;

as 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 sand and gravel, roadfill, and topsoil. They can use

it to identify areas where bedrock, wetness, or very

firm soil layers can cause difficulty in excavation.

Health officials, highway officials, engineers, and

others may also find this survey useful. The survey

can help them plan the safe disposal of wastes and

locate sites for pavements, sidewalks, campgrounds,

playgrounds, lawns, and trees and shrubs.

Interpretive Ratings

The interpretive tables in this survey rate the soils in

the survey area for various uses. Many of the tables

identify the limitations that affect specified uses and

indicate the severity of those limitations. The ratings in

these tables are both verbal and numerical.

Rating Class Terms

Rating classes are expressed in the tables in terms

that indicate the extent to which the soils are limited by

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

terms that indicate the suitability of the soils for the

use. Thus, the tables may show limitation classes or

suitability classes. Terms for the limitation classes are

not limited, somewhat limited, and very limited. The

suitability ratings are expressed as well suited,

moderately suited, poorly suited, and unsuited or as

good, fair, and poor.

Numerical Ratings

Numerical ratings in the tables indicate the relative

severity of individual limitations. The ratings are shown

as decimal fractions ranging from 0.00 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

and the point at which the soil feature is not a

limitation. The limitations appear in order from the

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

one limitation is identified, the most severe limitation is

listed first and the least severe one is listed last.

Crops and Pasture

General management needed for crops and pasture

is suggested in this section. The estimated yields of

the main crops and pasture plants are listed, the

system of land capability classification used by the

Natural Resources Conservation Service is explained,

and prime farmland is described.

Planners of management systems for individual

fields or farms should consider the information given in

the description of each soil under the heading

“Detailed Soil Map Units.” Specific information can be

obtained from the local office of the Natural Resources

Conservation Service or the Cooperative Extension

Service.

Use and Management of the Soils
64 Soil Survey of

Cropland Management Considerations

The management concerns affecting the use of the

detailed soil map units for crops are shown in table 5.

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.

Some of the considerations shown in the table

cannot be easily overcome. These are channels,

flooding, gullies, and ponding.

Additional considerations include the following:

Lime content, limited available water capacity,

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 in areas of 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.

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, and causes

erosion. Also, it can increase wetness and soil salinity.

include any rock fragment modifier, except for gravelly,

channery, stony, very stony, extremely stony, bouldery,

very bouldery, and extremely bouldery.

Surface stones (equipment limitation).—The word

“stony” or “bouldery” is included in the description of

the surface layer, or at least 0.01 percent of the

surface is covered with boulders.

Water erosion.—Either the slope is 6 percent or

more, or the slope is more than 3 percent and less

than 6 percent and the surface layer is not sandy.

Wind erosion.—The wind erodibility group is 1, 2, 3,

or 4L.

Hydrologic groups are described under the heading

“Water Features.” Erosion factors (e.g., K factor) and

wind erodibility groups are described under the

heading “Physical Properties.”

Crop Yield Estimates

The average yields per acre that can be expected

of the principal crops under a high level of

management are shown in table 6. In any given year,

yields may be higher or lower than those indicated in

the table because of variations in rainfall and other

climatic factors. The land capability classification of

each soil also is shown in the table.

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

(fig. 7), erosion control, and protection from flooding;

the proper planting and seeding rates; suitable highyielding crop varieties; appropriate and timely tillage;

control of weeds, plant diseases, and harmful insects;

favorable soil reaction and optimum levels of nitrogen,

phosphorus, potassium, and trace elements for each

crop; effective use of crop residue, barnyard manure,

and green manure crops; and harvesting that ensures

the smallest possible loss.

The estimated yields reflect the productive capacity

of each soil for each of the principal crops. Yields are

likely to increase as new production technology is

developed. The productivity of a given soil compared

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

change.

Crops other than those shown in table 6 are grown

in the survey area, but estimated yields are not listed

because the acreage of such crops is small. The local

office of the Natural Resources Conservation Service

or of the Cooperative Extension Service can provide

information about the management and productivity of

the soils for those crops.

Table 6 also shows the corn suitability rating (CSR)

for the soils in the survey area. Corn suitability ratings

provide a relative ranking of all soils mapped in the

State of Iowa based on their potential to be utilized for

the intensive production of row crops. The CSR is an

index that can be used to rate the potential production

of one soil compared with another over a period of

time. The CSR considers average weather conditions

and frequency of use of the soil for row crops. Ratings

range from 100 for soils that have no physical

limitations, are on minimal slopes, and can be

continuously row cropped to as low as 5 for soils that

have severe limitations affecting the production of row

crops. The ratings listed in this table assume adequate

management, natural weather conditions (no

irrigation), artificial drainage where required, and no

land leveling or terracing. They also assume that soils

in the lower positions on the landscape are not

affected by frequent damaging floods. The weighted

CSR for a given field can be modified by the

occurrence of sandy spots, local deposits, rock and

gravel outcrops, field boundaries, and noncrossable

drainageways. Even though predicted average yields

will change with time, the CSRs are expected to

remain relatively constant in relation to one another.

The CSRs in Woodbury County range from 80 (for

map unit 212, as an example) to 5 (for map unit 1G, as

an example). No ratings are provided for

miscellaneous areas because of the variability of

properties and use of these areas.
66 Soil Survey of

Inherent subsoil fertility levels, in terms of potential

plant-available phosphorus and potassium, also are

given in table 6. Soil tests of the tilled layer are used to

determine the most profitable rates of fertilizers for

various crops. Nutrient levels in the subsurface layers

influence crop yields, particularly in the drier seasons

when the nutrients in the dry tilled layer become

temporarily unavailable to plants. The availability of

nutrients in the tilled layer and the subsoil influences

the relative uptake from the two zones in the soil

profile. Fertilizer recommendations based on soil tests

of the tilled layer may be adjusted by the average

nutrient levels in the subsoil of each soil series. The

ratings given in the table are described as follows:

Subsoil phosphorus.—The amount of plantavailable phosphorus in the subsoil expressed in parts

per million and based on the weighted average of airdried soil samples from the subsoil (at a depth of 30 to

42 inches). (The value listed for complexes is the most

limiting value of the soils identified in the map unit

name.) A rating of very low indicates less than 7.5

ppm; low, 7.5 to 13.0 ppm; medium, 13.0 to 22.5 ppm;

and high, more than 22.5 ppm.

Subsoil potassium.—The amount of plant-available

potassium in the subsoil expressed in parts per million

and based on the weighted average of air-dried soil

samples from the subsoil (at a depth of 12 to 24

inches). (The value listed for complexes is the most

limiting value of the soils identified in the map unit

name.) A rating of very low indicates less than 50

ppm; low, 50 to 79 ppm; medium, 79 to 125 ppm; and

high, more than 125 ppm.

Pasture and Hayland Interpretations

Under good management, proper grazing is

essential for the production of high-quality forage,

stand survival, and erosion control. Proper grazing

Figure 7.—Surface drains are needed to remove excess water in this area of Luton silty clay, 0 to 2 percent slopes, rarely flooded.

Tile drainage is not effective because the soil is too clayey and permeability is restricted.
Woodbury County, Iowa 67

helps plants to maintain sufficient and generally

vigorous top growth during the growing season. Brush

control is essential in many areas, and weed control

generally is needed. Rotation grazing and renovation

also are important management practices.

The average yields per acre that can be expected

of the principal pasture and hay crops under a high

level of management are shown in table 7. Yield

estimates are often provided in animal unit months

(AUM), or the amount of forage or feed required to

feed one animal unit (one cow, one horse, one mule,

five sheep, or five goats) for 30 days.

The local office of the Natural Resources

Conservation Service or of the Cooperative Extension

Service can provide information about forage yields

other than those shown in the table.

Land Capability Classification

Land capability classification shows, in a general

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

Crops that require special management are excluded.

The soils are grouped according to their limitations for

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

crops, and the way they respond to management. The

criteria used in grouping the soils do not take into

account 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 woodland or for

engineering purposes.

In the capability system, soils generally are grouped

at three levels—capability class, subclass, and unit

(USDA, 1961). These categories indicate the degree

and kinds of limitations affecting mechanized farming

systems that produce the more commonly grown field

crops, such as corn, small grain, cotton, hay, and fieldgrown 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

woodland. 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 woodland without a level of management

that is impractical. These areas may have potential for

other uses, such as recreational facilities and wildlife

habitat.

Capability subclasses identify the dominant kind of

limitation in the class. They are designated by adding a

small letter, e, w, s, or c, to the class numeral, for

example, 2e. The letter e shows that the main hazard

is the risk of erosion unless a close-growing plant

cover is maintained; w shows that water in or on the

soil interferes with plant growth or cultivation (in some

soils the wetness has been 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, woodland, wildlife habitat, or

recreation.

The capability classification of the soils in the

survey area is given in tables 6 and 7.

Prime Farmland

Prime farmland is of major importance in meeting

the Nation’s short- and long-range needs for food and

fiber. The acreage of high-quality farmland is limited,

and the U.S. Department of Agriculture recognizes

that government at local, State, and Federal levels, as

well as individuals, must encourage and facilitate the

wise use of our Nation’s prime farmland.

Prime farmland soils, as defined by the U.S.

Department of Agriculture, are soils that are best

suited to food, feed, forage, fiber, and oilseed crops.

Such soils have properties that favor the economic

production of sustained high yields of crops. The soils

need only to be treated and managed by acceptable

farming methods. An adequate moisture supply and a
68 Soil Survey of

sufficiently long growing season are required. Prime

farmland soils produce the highest yields with minimal

expenditure of energy and economic resources, and

farming these soils results in the least damage to the

environment.

Prime farmland soils may presently be used as

cropland, pasture, or woodland or for other purposes.

They either are used for food and fiber or are available

for these uses. Urban or built-up land, public land, and

water areas cannot be considered prime farmland.

Urban or built-up land is any contiguous unit of land 10

acres or more in size that is used for such purposes

as housing, industrial, and commercial sites, sites for

institutions or public buildings, small parks, golf

courses, cemeteries, railroad yards, airports, sanitary

landfills, sewage treatment plants, and water-control

structures. Public land is land not available for farming

in National forests, National parks, military

reservations, and State parks.

Prime farmland soils commonly receive an

adequate and dependable supply of moisture from

precipitation or irrigation. The temperature and growing

season are favorable, and the level of acidity or

alkalinity and the content of salts and sodium are

acceptable. The soils have few, if any, rocks and are

permeable to water and air. They are not excessively

erodible or saturated with water for long periods, and

they are not frequently flooded during the growing

season or are protected from flooding. Slopes range

mainly from 0 to 6 percent.

Soils that have a high water table or are subject to

flooding may qualify as prime farmland where these

limitations are overcome by drainage measures or

flood control. Onsite evaluation is necessary to

determine the effectiveness of corrective measures.

More information about the criteria for prime farmland

can be obtained at the local office of the Natural

Resources Conservation Service.

A recent trend in land use has been the conversion

of prime farmland to urban and industrial uses. The

loss of prime farmland to other uses puts pressure on

lands that are less productive than prime farmland.

About 126,209 acres, or 22 percent of the survey

area, meets the requirements for prime farmland.

The map units in the survey area that meet the

requirements for prime farmland are listed in table 8.

This list does not constitute a recommendation for a

particular land use. On some soils included in the

table, measures that overcome limitations are needed.

The need for these measures is indicated in

parentheses after the map unit name. The location of

each map unit is shown on the detailed soil maps. The

soil qualities that affect use and management are

described in the section “Detailed Soil Map Units.”

Windbreaks and Environmental

Plantings

Windbreaks protect livestock, buildings, yards, fruit

trees, gardens, and cropland from wind and snow;

help to keep snow on fields; and provide food and

cover for wildlife. Field windbreaks are narrow

plantings made at right angles to the prevailing wind

and at specific intervals across the field. The interval

depends on the erodibility of the soil.

Environmental plantings help to beautify and screen

houses and other buildings and to abate noise. The

plants, mostly evergreen shrubs and trees, are closely

spaced. To ensure plant survival, a healthy planting

stock of suitable species should be planted properly

on a well prepared site and maintained in good

condition.

Table 9 shows the height that locally grown trees

and shrubs are expected to reach in 20 years on

various soils. The estimates in table 9 are based on

measurements and observation of established

plantings that have been given adequate care. They

can be used as a guide in planning windbreaks and

screens. Additional information on planning

windbreaks and screens and planting and caring for

trees and shrubs can be obtained from the local office

of the Natural Resources Conservation Service or of

the Cooperative Extension Service or from a

commercial nursery.

Recreation

The soils of the survey area are rated in tables 10a

and 10b 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
Woodbury County, Iowa 69

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

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

limitation (0.00).

The ratings in the tables are based on restrictive

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

the surface layer. Susceptibility to flooding is

considered. Not considered in the ratings, but

important in evaluating a site, are the location and

accessibility of the area, the size and shape of the

area and its scenic quality, vegetation, access to

water, potential water impoundment sites, and access

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

septic tank effluent and the ability of the soil to support

vegetation also are important. Soils that are subject to

flooding are limited for recreational uses by the

duration and intensity of flooding and the season when

flooding occurs. In planning recreational facilities,

onsite assessment of the height, duration, intensity,

and frequency of flooding is essential.

The information in tables 10a and 10b can be

supplemented by other information in this survey, for

example, interpretations for building site development,

construction materials, sanitary facilities, and water

management.

Camp areas require site preparation, such as

shaping and leveling the tent and parking areas,

stabilizing roads and intensively used areas, and

installing sanitary facilities and utility lines. Camp

areas are subject to heavy foot traffic and some

vehicular traffic. The ratings are based on the soil

properties that affect the ease of developing camp

areas and the performance of the areas after

development. Slope, stoniness, and depth to bedrock

or a cemented pan are the main concerns affecting

the development of camp areas. The soil properties

that affect the performance of the areas after

development are those that influence trafficability and

promote the growth of vegetation, especially in heavily

used areas. For good trafficability, the surface of camp

areas should absorb rainfall readily, remain firm under

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Picnic areas are subject to heavy foot traffic. Most

vehicular traffic is confined to access roads and

parking areas. The ratings are based on the soil

properties that affect the ease of developing picnic

areas and that influence trafficability and the growth of

vegetation after development. Slope and stoniness are

the main concerns affecting the development of picnic

areas. For good trafficability, the surface of picnic

areas should absorb rainfall readily, remain firm under

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Playgrounds require soils that are nearly level, are

free of stones, and can withstand intensive foot traffic.

The ratings are based on the soil properties that affect

the ease of developing playgrounds and that influence

trafficability and the growth of vegetation after

development. Slope and stoniness are the main

concerns affecting the development of playgrounds.

For good trafficability, the surface of the playgrounds

should absorb rainfall readily, remain firm under heavy

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

properties that influence trafficability are texture of the

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

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Paths and trails for hiking and horseback riding

should require little or no slope modification through

cutting and filling. The ratings are based on the soil

properties that affect trafficability and erodibility. These

properties are stoniness, depth to a water table,

ponding, flooding, slope, and texture of the surface

layer.

Off-road motorcycle trails require little or no site

preparation. They are not covered with surfacing

material or vegetation. Considerable compaction of the

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

properties that influence erodibility, trafficability,

dustiness, and the ease of revegetation. These

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

ponding, flooding, and texture of the surface layer.

Golf fairways are subject to heavy foot traffic and

some light vehicular traffic. Cutting or filling may be

required. Irrigation is not considered in the ratings. The

ratings are based on the soil properties that affect

plant growth and trafficability after vegetation is

established. The properties that affect plant growth are

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

bedrock or a cemented pan; the available water

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

sodium, or calcium carbonate; and sulfidic materials.

The properties that affect trafficability are flooding,
70 Soil Survey of

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

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

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

roughs, and greens is not considered in the ratings.

Wildlife Habitat

Soils affect the kind and amount of vegetation that

is available to wildlife as food and cover. They also

affect the construction of water impoundments. The

kind and abundance of wildlife depend largely on the

amount and distribution of food, cover, and water.

Wildlife habitat can be created or improved by planting

appropriate vegetation, by maintaining the existing

plant cover, or by promoting the natural establishment

of desirable plants.

In table 11, the soils in the survey area are rated

according to their potential for providing habitat for

various kinds of wildlife. This information can be used

in planning parks, wildlife refuges, nature study areas,

and other developments for wildlife; in selecting soils

that are suitable for establishing, improving, or

maintaining specific elements of wildlife habitat; and in

determining the intensity of management needed for

each element of the habitat.

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

very poor. A rating of good indicates that the element

or kind of habitat is easily established, improved, or

maintained. Few or no limitations affect management,

and satisfactory results can be expected. A rating of

fair indicates that the element or kind of habitat can be

established, improved, or maintained in most places.

Moderately intensive management is required for

satisfactory results. A rating of poor indicates that

limitations are severe for the designated element or

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

maintained in most places, but management is difficult

and must be intensive. A rating of very poor indicates

that restrictions for the element or kind of habitat are

very severe and that unsatisfactory results can be

expected. Creating, improving, or maintaining habitat

is impractical or impossible.

The elements of wildlife habitat are described in the

following paragraphs.

Grain and seed crops are domestic grains and

seed-producing herbaceous plants. Soil properties

and features that affect the growth of grain and seed

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

layer, available water capacity, wetness, slope, surface

stoniness, and flooding. Soil temperature and soil

moisture also are considerations. Examples of grain

and seed crops are corn, soybeans, wheat, oats, and

barley.

Grasses and legumes are domestic perennial

grasses and herbaceous legumes. Soil properties and

features that affect the growth of grasses and legumes

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

available water capacity, wetness, surface stoniness,

flooding, and slope. Soil temperature and soil moisture

also are considerations. Examples of grasses and

legumes are bromegrass, timothy, orchardgrass,

clover, and alfalfa.

Wild herbaceous plants are native or naturally

established grasses and forbs, including weeds. Soil

properties and features that affect the growth of these

plants are depth of the root zone, texture of the

surface layer, available water capacity, wetness,

surface stoniness, and flooding. Soil temperature and

soil moisture also are considerations. Examples of wild

herbaceous plants are bluestem, bluegrass,

dandelions, goldenrod, ragweed, wheatgrass, and

nightshade.

Hardwood trees and woody understory produce

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

foliage. Soil properties and features that affect the

growth of hardwood trees and shrubs are depth of the

root zone, available water capacity, and wetness.

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

birch, maple, green ash, willow, and American elm.

Examples of fruit-producing shrubs that are suitable

for planting on soils rated good are Russian olive,

autumn olive, and crabapple.

Coniferous plants furnish browse and seeds. Soil

properties and features that affect the growth of

coniferous trees, shrubs, and ground cover are depth

of the root zone, available water capacity, and

wetness. Examples of coniferous plants are pine,

spruce, fir, cedar, and juniper.

Wetland plants are annual and perennial wild

herbaceous plants that grow on moist or wet sites

(fig. 8). Submerged or floating aquatic plants are

excluded. Soil properties and features affecting

wetland plants are texture of the surface layer,

wetness, reaction, salinity, slope, and surface

stoniness. Examples of wetland plants are smartweed,

wild millet, wildrice, rushes, sedges, and reeds.

Shallow water areas have an average depth of less

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

created by dams, levees, or other water-control

structures. Soil properties and features affecting

shallow water areas are depth to bedrock, wetness,

surface stoniness, slope, and permeability. Examples

of shallow water areas are marshes, waterfowl feeding

areas, and ponds.

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
Woodbury County, Iowa 71

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, woodcock, thrushes, woodpeckers, owls, tree

squirrels, gray fox, raccoon, and deer.

Habitat for wetland wildlife consists of open, marshy

or swampy shallow water areas. Some of the wildlife

attracted to such areas are ducks, geese, herons,

shore birds, muskrat, mink, and beaver.

Engineering

This section provides information for planning land

uses related to urban development and to water

management. Soils are rated for various uses, and the

most limiting features are identified. Ratings are given

for building site development, sanitary facilities,

construction materials, and water management. The

ratings are based on observed performance of the

soils and on the data in the tables described under the

heading “Soil Properties.”

Information in this section is intended for land use

planning, for evaluating land use alternatives, and for

planning site investigations prior to design and

construction. The information, however, has limitations.

For example, estimates and other data generally apply

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

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

areas of different soils may be included within the

mapped areas of a specific soil.

The information is not site specific and does not

eliminate the need for onsite investigation of the soils

or for testing and analysis by personnel experienced in

the design and construction of engineering works.

Government ordinances and regulations that

restrict certain land uses or impose specific design

criteria were not considered in preparing the

information in this section. Local ordinances and

regulations should be considered in planning, in site

selection, and in design.

Soil properties, site features, and observed

performance were considered in determining the

Figure 8.—A few remaining undrained areas of Albaton soils support an abundance of wetland plants and provide excellent habitat

for many species of wildlife.
72 Soil Survey of

ratings in this section. During the fieldwork for this soil

survey, determinations were made about particle-size

distribution, liquid limit, plasticity index, soil reaction,

depth to bedrock, hardness of bedrock within 5 to 7

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

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

structure aggregation, and soil density. Data were

collected about kinds of clay minerals, mineralogy of

the sand and silt fractions, and the kinds of adsorbed

cations. Estimates were made for erodibility,

permeability, corrosivity, shrink-swell potential,

available water capacity, and other behavioral

characteristics affecting engineering uses.

This information can be used to evaluate the

potential of areas for residential, commercial,

industrial, and recreational uses; make preliminary

estimates of construction conditions; evaluate

alternative routes for roads, streets, highways,

pipelines, and underground cables; evaluate

alternative sites for sanitary landfills, septic tank

absorption fields, and sewage lagoons; plan detailed

onsite investigations of soils and geology; locate

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

plan drainage systems, irrigation systems, ponds,

terraces, and other structures for soil and water

conservation; and predict performance of proposed

small structures and pavements by comparing the

performance of existing similar structures on the same

or similar soils.

The information in the tables, along with the soil

maps, the soil descriptions, and other data provided in

this survey, can be used to make additional

interpretations.

Some of the terms used in this soil survey have a

special meaning in soil science and are defined in the

Glossary.

Building Site Development

Soil properties influence the development of

building sites, including the selection of the site, the

design of the structure, construction, performance

after construction, and maintenance. Tables 12a and

12b show the degree and kind of soil limitations that

affect dwellings with and without basements, small

commercial buildings, local roads and streets, shallow

excavations, and lawns and landscaping.

The ratings in the tables are both verbal and

numerical. Rating class terms indicate the extent to

which the soils are limited by all of the soil features

that affect building site development. Not limited

indicates that the soil has features that are very

favorable for the specified use. Good performance and

very low maintenance can be expected. Somewhat

limited indicates that the soil has features that are

moderately favorable for the specified use. The

limitations can be overcome or minimized by special

planning, design, or installation. Fair performance and

moderate maintenance can be expected. Very limited

indicates that the soil has one or more features that

are unfavorable for the specified use. The limitations

generally cannot be overcome without major soil

reclamation, special design, or expensive installation

procedures. Poor performance and high maintenance

can be expected.

Numerical ratings in the tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

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

limitation (0.00).

Dwellings are single-family houses of three stories

or less. For dwellings without basements, the

foundation is assumed to consist of spread footings of

reinforced concrete built on undisturbed soil at a depth

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

whichever is deeper. For dwellings with basements,

the foundation is assumed to consist of spread

footings of reinforced concrete built on undisturbed soil

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

based on the soil properties that affect the capacity of

the soil to support a load without movement and on

the properties that affect excavation and construction

costs. The properties that affect the load-supporting

capacity include depth to a water table, ponding,

flooding, subsidence, linear extensibility (shrink-swell

potential), and compressibility. Compressibility is

inferred from the Unified classification. The properties

that affect the ease and amount of excavation include

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

to bedrock or a cemented pan, hardness of bedrock or

a cemented pan, and the amount and size of rock

fragments.

Small commercial buildings are structures that are

less than three stories high and do not have

basements. The foundation is assumed to consist of

spread footings of reinforced concrete built on

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

maximum frost penetration, whichever is deeper. The

ratings are based on the soil properties that affect the

capacity of the soil to support a load without

movement and on the properties that affect excavation

and construction costs. The properties that affect the

load-supporting capacity include depth to a water

table, ponding, flooding, subsidence, linear
Woodbury County, Iowa 73

extensibility (shrink-swell potential), and

compressibility (which is inferred from the Unified

classification). The properties that affect the ease and

amount of excavation include flooding, depth to a

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

cemented pan, hardness of bedrock or a cemented

pan, and the amount and size of rock fragments.

Local roads and streets have an all-weather surface

and carry automobile and light truck traffic all year.

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

of gravel, crushed rock, or soil material stabilized by

lime or cement; and a surface of flexible material

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

binder. The ratings are based on the soil properties

that affect the ease of excavation and grading and the

traffic-supporting capacity. The properties that affect

the ease of excavation and grading are depth to

bedrock or a cemented pan, hardness of bedrock or a

cemented pan, depth to a water table, ponding,

flooding, the amount of large stones, and slope. The

properties that affect the traffic-supporting capacity

are soil strength (as inferred from the AASHTO group

index number), subsidence, linear extensibility (shrinkswell potential), the potential for frost action, depth to a

water table, and ponding.

Shallow excavations are trenches or holes dug to a

maximum depth of 5 or 6 feet for graves, utility lines,

open ditches, or other purposes. The ratings are

based on the soil properties that influence the ease of

digging and the resistance to sloughing. Depth to

bedrock or a cemented pan, hardness of bedrock or a

cemented pan, the amount of large stones, and dense

layers influence the ease of digging, filling, and

compacting. Depth to the seasonal high water table,

flooding, and ponding may restrict the period when

excavations can be made. Slope influences the ease

of using machinery. Soil texture, depth to the water

table, and linear extensibility (shrink-swell potential)

influence the resistance to sloughing.

Lawns and landscaping require soils on which turf

and ornamental trees and shrubs can be established

and maintained. Irrigation is not considered in the

ratings. The ratings are based on the soil properties

that affect plant growth and trafficability after

vegetation is established. The properties that affect

plant growth are reaction; depth to a water table;

ponding; depth to bedrock or a cemented pan; the

available water capacity in the upper 40 inches; the

content of salts, sodium, or calcium carbonate; and

sulfidic materials. The properties that affect

trafficability are flooding, depth to a water table,

ponding, slope, stoniness, and the amount of sand,

clay, or organic matter in the surface layer.

Sanitary Facilities

Tables 13a and 13b 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 72 inches or

between a depth of 24 inches and a restrictive layer is

evaluated. The ratings are based on the soil properties

that affect absorption of the effluent, construction and

maintenance of the system, and public health.

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

bedrock or a cemented pan, and flooding affect

absorption of the effluent. Stones and boulders, ice, and

bedrock or a cemented pan interfere with installation.

Subsidence interferes with installation and maintenance.

Excessive slope may cause lateral seepage and

surfacing of the effluent in downslope areas.

Some soils are underlain by loose sand and gravel

or fractured bedrock at a depth of less than 4 feet

below the distribution lines. In these soils the

absorption field may not adequately filter the effluent,

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

ground water may become contaminated.

Sewage lagoons are shallow ponds constructed to

hold sewage while aerobic bacteria decompose the

solid and liquid wastes. Lagoons should have a nearly
74 Soil Survey of

level floor surrounded by cut slopes or embankments

of compacted soil. Nearly impervious soil material for

the lagoon floor and sides is required to minimize

seepage and contamination of ground water.

Considered in the ratings are slope, permeability,

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

cemented pan, flooding, large stones, and content of

organic matter.

Soil permeability is a critical property affecting the

suitability for sewage lagoons. Most porous soils

eventually become sealed when they are used as sites

for sewage lagoons. Until sealing occurs, however, the

hazard of pollution is severe. Soils that have a

permeability rate of more than 2 inches per hour are

too porous for the proper functioning of sewage

lagoons. In these soils, seepage of the effluent can

result in contamination of the ground water. Groundwater contamination is also a hazard if fractured

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

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

lagoon, or if floodwater overtops the lagoon.

A high content of organic matter is detrimental to

proper functioning of the lagoon because it inhibits

aerobic activity. Slope, bedrock, and cemented pans

can cause construction problems, and large stones

can hinder compaction of the lagoon floor. If the

lagoon is to be uniformly deep throughout, the slope

must be gentle enough and the soil material must be

thick enough over bedrock or a cemented pan to make

land smoothing practical.

A trench sanitary landfill is an area where solid

waste is placed in successive layers in an excavated

trench. The waste is spread, compacted, and covered

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

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

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

in the table are based on the soil properties that affect

the risk of pollution, the ease of excavation,

trafficability, and revegetation. These properties

include permeability, depth to bedrock or a cemented

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

texture, stones and boulders, highly organic layers,

soil reaction, and content of salts and sodium. Unless

otherwise stated, the ratings apply only to that part of

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

trenches, onsite investigation may be needed.

Hard, nonrippable bedrock, creviced bedrock, or

highly permeable strata in or directly below the

proposed trench bottom can affect the ease of

excavation and the hazard of ground-water pollution.

Slope affects construction of the trenches and the

movement of surface water around the landfill. It also

affects the construction and performance of roads in

areas of the landfill.

Soil texture and consistence affect the ease with

which the trench is dug and the ease with which the

soil can be used as daily or final cover. They

determine the workability of the soil when dry and

when wet. Soils that are plastic and sticky when wet

are difficult to excavate, grade, or compact and are

difficult to place as a uniformly thick cover over a layer

of refuse.

The soil material used as the final cover for a trench

landfill should be suitable for plants. It should not have

excess sodium or salts and should not be too acid.

The surface layer generally has the best workability,

the highest content of organic matter, and the best

potential for plants. Material from the surface layer

should be stockpiled for use as the final cover.

In an area sanitary landfill, solid waste is placed in

successive layers on the surface of the soil. The waste

is spread, compacted, and covered daily with a thin

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

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

the completed landfill. The ratings in the table are

based on the soil properties that affect trafficability and

the risk of pollution. These properties include flooding,

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

and depth to bedrock or a cemented pan.

Flooding is a serious problem because it can result

in pollution in areas downstream from the landfill. If

permeability is too rapid or if fractured bedrock, a

fractured cemented pan, or the water table is close to

the surface, the leachate can contaminate the water

supply. Slope is a consideration because of the extra

grading required to maintain roads in the steeper

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

surface of the soils in the steeper areas and cause

difficult seepage problems.

Daily cover for landfill is the soil material that is

used to cover compacted solid waste in an area

sanitary landfill. The soil material is obtained offsite,

transported to the landfill, and spread over the waste.

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

a landfill. They are based on the soil properties that

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

moving and spreading the material over the refuse

daily during wet and dry periods. These properties

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

rock fragments, slope, depth to bedrock or a cemented

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

Loamy or silty soils that are free of large stones and

excess gravel are the best cover for a landfill. Clayey

soils may be sticky and difficult to spread; sandy soils

are subject to wind erosion.

Slope affects the ease of excavation and of moving

the cover material. Also, it can influence runoff,

erosion, and reclamation of the borrow area.
Woodbury County, Iowa 75

After soil material has been removed, the soil

material remaining in the borrow area must be thick

enough over bedrock, a cemented pan, or the water

table to permit revegetation. The soil material used as

the final cover for a landfill should be suitable for

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

and should not be too acid.

Construction Materials

Tables 14a and 14b give information about the soils

as potential sources of gravel, sand, reclamation

material, roadfill, and topsoil. Normal compaction,

minor processing, and other standard construction

practices are assumed.

Sand and gravel are natural aggregates suitable for

commercial use with a minimum of processing. They

are used in many kinds of construction (fig. 9).

Specifications for each use vary widely. In table 14a,

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 as possible, probable, or

improbable sources of gravel and are rated good, fair,

or poor as potential sources of sand. In this table,

gravel is defined as particles ranging from 0.2 inch to

3.0 inches in diameter. Soils rated as a possible

source of gravel contain at least 25 percent gravel, by

weight. Soils rated as a probable source contain at

least 50 percent gravel, by weight. The likelihood of the

soil being a source of gravel is reduced by the content

of rock fragments larger than 3 inches in diameter. For

sand, a rating of good or fair means that the source

material is likely to be in or below the soil. For both

sand and gravel, 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

Figure 9.—An area of Pits, sand and gravel. This map unit is an excellent source of aggregate for road building. These pits are

common throughout the Little Sioux River valley.
76 Soil Survey of

that the layer is a poor source. The number 1.00

indicates that the layer is a good source. A number

between 0.00 and 1.00 indicates the degree to which

the layer is a likely source.

In table 14b, the soils are rated good, fair, or poor

as potential sources of reclamation material, roadfill,

and topsoil. The features that limit the soils as sources

of these materials are specified in the table. The

numerical ratings given after the specified features

indicate the degree to which the features limit the soils

as sources of reclamation material, roadfill, or topsoil.

The lower the number, the greater the limitation.

Reclamation material is used in areas that have

been drastically disturbed by surface mining or similar

activities. When these areas are reclaimed, layers of

soil material or unconsolidated geological material, or

both, are replaced in a vertical sequence. The

reconstructed soil favors plant growth. The ratings in

the table do not apply to quarries and other mined

areas that require an offsite source of reconstruction

material. The ratings are based on the soil properties

that affect erosion and stability of the surface and the

productive potential of the reconstructed soil. These

properties include the content of sodium, salts, and

calcium carbonate; reaction; available water capacity;

erodibility; texture; content of rock fragments; and

content of organic matter and other features that affect

fertility.

Roadfill is soil material that is excavated in one

place and used in road embankments in another

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

roadfill for low embankments, generally less than 6

feet high and less exacting in design than higher

embankments.

The ratings are for the whole soil, from the surface

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

will be mixed when the soil material is excavated and

spread.

The ratings are based on the amount of suitable

material and on soil properties that affect the ease of

excavation and the performance of the material after it

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

major consideration. The ease of excavation is

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

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

been compacted and drained is determined by its

strength (as inferred from the AASHTO classification

of the soil) and linear extensibility (shrink-swell

potential).

Topsoil is used to cover an area so that vegetation

can be established and maintained. The upper 40

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

evaluated is the reclamation potential of the borrow

area. The ratings are based on the soil properties that

affect plant growth; the ease of excavating, loading,

and spreading the material; and reclamation of the

borrow area. Toxic substances, soil reaction, and the

properties that are inferred from soil texture, such as

available water capacity and fertility, affect plant

growth. The ease of excavating, loading, and

spreading is affected by rock fragments, slope, depth

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

material. Reclamation of the borrow area is affected by

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

bedrock or a cemented pan, and toxic material.

The surface layer of most soils is generally

preferred for topsoil because of its organic matter

content. Organic matter greatly increases the

absorption and retention of moisture and nutrients for

plant growth.

Water Management

Table 15 gives information on the soil properties

and site features that affect water management. The

degree and kind of soil limitations are given for pond

reservoir areas; embankments, dikes, and levees; 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 permeability of
Woodbury County, Iowa 77

the soil and the depth to fractured bedrock or other

permeable material. Excessive slope can affect the

storage capacity of the reservoir area.

Embankments, dikes, and levees are raised

structures of soil material, generally less than 20 feet

high, constructed to impound water or to protect land

against overflow. Embankments that have zoned

construction (core and shell) are not considered. In

this table, the soils are rated as a source of material

for embankment fill. The ratings apply to the soil

material below the surface layer to a depth of 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

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.

Table 16 shows 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. Foodprocessing 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 this table, 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 in the table 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 and food-processing waste,

application of sewage sludge, and disposal of

wastewater by irrigation).

The ratings are both verbal and numerical. Rating

class terms indicate the extent to which the soils are

limited by all of the soil features that affect 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 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).

Application of manure and food-processing waste

not only disposes of waste material but also can

improve crop production by increasing the supply of
78

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 permeability,

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.

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 permeability,

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, permeability, 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.
79

Data relating to soil properties are collected during

the course of the soil survey.

Soil properties are ascertained by field examination

of the soils and by laboratory index testing of some

benchmark soils. Established standard procedures are

followed. During the survey, many shallow borings are

made and examined to identify and classify the soils

and to delineate them on the soil maps. Samples are

taken from some typical profiles and tested in the

laboratory to determine particle-size distribution,

plasticity, and compaction characteristics.

Estimates of soil properties are based on field

examinations, on laboratory tests of samples from the

survey area, and on laboratory tests of samples of

similar soils in nearby areas. Tests verify field

observations, verify properties that cannot be

estimated accurately by field observation, and help to

characterize key soils.

The estimates of soil properties are shown in

tables. They include engineering index properties,

physical and chemical properties, and pertinent soil

and water features.

Engineering Index Properties

Table 17 gives the engineering classifications and

the range of index properties for the layers of each soil

in the survey area.

Depth to the upper and lower boundaries of each

layer is indicated.

Texture is given in the standard terms used by the

U.S. Department of Agriculture. These terms are

defined according to percentages of sand, silt, and

clay in the fraction of the soil that is less than 2

millimeters in diameter. “Loam,” for example, is soil that

is 7 to 27 percent clay, 28 to 50 percent silt, and less

than 52 percent sand (fig. 10). 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

Soil Properties

Figure 10.—Percentages of clay, silt, and sand in the basic

USDA soil textural classes.
80 Soil Survey of

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

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

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

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

visual inspection.

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

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

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

additional refinement, the suitability of a soil as

subgrade material can be indicated by a group index

number. Group index numbers range from 0 for the

best subgrade material to 20 or higher for the poorest.

Rock fragments larger than 10 inches in diameter

and 3 to 10 inches in diameter are indicated as a

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

percentages are estimates determined mainly by

converting volume percentage in the field to weight

percentage.

Percentage (of soil particles) passing designated

sieves is the percentage of the soil fraction less than 3

inches in diameter based on an ovendry weight. The

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

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

millimeters, respectively. Estimates are based on

laboratory tests of soils sampled in the survey area

and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits)

indicate the plasticity characteristics of a soil. The

estimates are based on test data from the survey area

or from nearby areas and on field examination.

The estimates of particle-size distribution, liquid

limit, and plasticity index are generally rounded to the

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

Atterberg limits extend a marginal amount (1 or 2

percentage points) across classification boundaries,

the classification in the marginal zone is generally

omitted in the table.

Physical Properties

Table 18 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.

Clay as a soil separate consists of mineral soil

particles that are less than 0.002 millimeter in

diameter. In table 18, the estimated clay content of

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

the soil material that is less than 2 millimeters in

diameter.

The amount and kind of clay affect the fertility and

physical condition of the soil and the ability of the soil

to adsorb cations and to retain moisture. They

influence shrink-swell potential, permeability, plasticity,

the ease of soil dispersion, and other soil properties.

The amount and kind of clay in a soil also affect tillage

and earthmoving operations.

Moist bulk density is the weight of soil (ovendry) per

unit volume. Volume is measured when the soil is at

field moisture capacity, that is, the moisture content at

1

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

Weight is determined after the soil is dried at 105

degrees C. In the table, the estimated moist bulk

density of each soil horizon is expressed in grams per

cubic centimeter of soil material that is less than 2

millimeters in diameter. Bulk density data are used to

compute shrink-swell potential, available water

capacity, total pore space, and other soil properties.

The moist bulk density of a soil indicates the pore

space available for water and roots. Depending on soil

texture, a bulk density of more than 1.4 can restrict

water storage and root penetration. Moist bulk density

is influenced by texture, kind of clay, content of organic

matter, and soil structure.

Permeability refers to the ability of a soil to transmit

water or air. The term “permeability,” as used in soil

surveys, indicates saturated hydraulic conductivity

(Ksat ). The estimates in the table indicate the rate of

water movement, in inches per hour, when the soil is

saturated. They are based on soil characteristics

observed in the field, particularly structure, porosity,

and texture. Permeability is considered in the design of

soil drainage systems and septic tank absorption

fields.

Available water capacity refers to the quantity of

water that the soil is capable of storing for use by

plants. The capacity for water storage is given in

inches of water per inch of soil for each soil layer. The

capacity varies, depending on soil properties that

affect retention of water. The most important

properties are the content of organic matter, soil

texture, bulk density, and soil structure. Available water

capacity is an important factor in the choice of plants

or crops to be grown and in the design and

management of irrigation systems. Available water

capacity is not an estimate of the quantity of water

actually available to plants at any given time.

Linear extensibility refers to the change in length of

an unconfined clod as moisture content is decreased

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

volume change between the water content of the clod
Woodbury County, Iowa 81

at 1

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

oven dryness. The volume change is reported in the

table as percent change for the whole soil. Volume

change is influenced by the amount and type of clay

minerals in the soil.

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

if the soil has a linear extensibility of less than 3

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

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

linear extensibility is more than 3, shrinking and

swelling can cause damage to buildings, roads, and

other structures and to plant roots. Special design

commonly is needed.

Organic matter is the plant and animal residue in

the soil at various stages of decomposition. In table

18, the estimated content of organic matter is

expressed as a percentage, by weight, of the soil

material that is less than 2 millimeters in diameter.

The content of organic matter in a soil can be

maintained by returning crop residue to the soil.

Organic matter has a positive effect on available water

capacity, water infiltration, soil organism activity, and

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

crops and soil organisms.

Erosion factors are shown in table 18 as the K

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

indicates the susceptibility of a soil to sheet and rill

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

the Universal Soil Loss Equation (USLE) and the

Revised Universal Soil Loss Equation (RUSLE) to

predict the average annual rate of soil loss by sheet

and rill erosion in tons per acre per year. The

estimates are based primarily on percentage of silt,

sand, and organic matter and on soil structure and

permeability. Values of K range from 0.02 to 0.69.

Other factors being equal, the higher the value, the

more susceptible the soil is to sheet and rill erosion by

water.

Erosion factor Kw indicates the erodibility of the

whole soil. The estimates are modified by the

presence of rock fragments.

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

size.

Erosion factor T is an estimate of the maximum

average annual rate of soil erosion by wind or water

that can occur without affecting crop productivity over

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

year.

Wind erodibility groups are made up of soils that

have similar properties affecting their susceptibility to

wind erosion in cultivated areas. The soils assigned to

group 1 are the most susceptible to wind erosion, and

those assigned to group 8 are the least susceptible.

Descriptions of these groups are available in the

National Soil Survey Handbook (USDA/NRCS).

Wind erodibility index is a numerical value indicating

the susceptibility of soil to wind erosion, or the tons

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

wind erosion. There is a close correlation between

wind erosion and the texture of the surface layer, the

size and durability of surface clods, rock fragments,

organic matter, and a calcareous reaction. Soil

moisture and frozen soil layers also influence wind

erosion.

Chemical Properties

Table 19 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 cationexchange capacity. The ability to retain cations

reduces the hazard of ground-water pollution.

Soil reaction is a measure of acidity or alkalinity.

The pH of each soil horizon is based on many field

tests. For many soils, values have been verified by

laboratory analyses. Soil reaction is important in

selecting crops and other plants, in evaluating soil

amendments for fertility and stabilization, and in

determining the risk of corrosion.

Calcium carbonate equivalent is the percent of

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

than 2 millimeters in size. The availability of plant

nutrients is influenced by the amount of carbonates in

the soil. Incorporating nitrogen fertilizer into calcareous

soils helps to prevent nitrite accumulation and

ammonium-N volatilization.

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.
82 Soil Survey of

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 is the ratio of the Na concentration divided

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

concentration. Soils that have SAR values of 13 or

more may be characterized by an increased

dispersion of organic matter and clay particles,

reduced permeability and aeration, and a general

degradation of soil structure.

Water Features

Table 20 gives estimates of various water features.

The estimates are used in land use planning that

involves engineering considerations.

Hydrologic soil groups are based on estimates of

runoff potential. Soils are assigned to one of four

groups according to the rate of water infiltration when

the soils are not protected by vegetation, are

thoroughly wet, and receive precipitation from longduration storms.

The four hydrologic soil groups are:

Group A. Soils having a high infiltration rate (low

runoff potential) when thoroughly wet. These consist

mainly of deep, well drained to excessively drained

sands or gravelly sands. These soils have a high rate

of water transmission.

Group B. Soils having a moderate infiltration rate

when thoroughly wet. These consist chiefly of

moderately deep or deep, moderately well drained or

well drained soils that have moderately fine texture to

moderately coarse texture. These soils have a

moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when

thoroughly wet. These consist chiefly of soils having a

layer that impedes the downward movement of water

or soils of moderately fine texture or fine texture.

These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate

(high runoff potential) when thoroughly wet. These

consist chiefly of clays that have a high shrink-swell

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

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

and soils that are shallow over nearly impervious

material. These soils have a very slow rate of water

transmission.

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

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

second is for undrained areas.

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.

Table 20 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. Table 20 indicates surface water depth

and the duration and frequency of ponding. Duration is

expressed as very brief if less than 2 days, brief if 2 to

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

30 days. Frequency is expressed as none, rare,

occasional, and frequent. None means that ponding is

not probable; rare that it is unlikely but possible under

unusual weather conditions (the chance of ponding is

nearly 0 percent to 5 percent in any year); occasional

that it occurs, on the average, once or less in 2 years

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

and frequent that it occurs, on the average, more than

once in 2 years (the chance of ponding is more than

50 percent in any year).

Flooding is the temporary inundation of an area

caused by overflowing streams, by runoff from

adjacent slopes, or by tides. Water standing for short

periods after rainfall or snowmelt is not considered

flooding, and water standing in swamps and marshes

is considered ponding rather than flooding.

Duration and frequency are estimated. Duration is

expressed as extremely brief if 0.1 hour to 4 hours,
Woodbury County, Iowa 83

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

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

Frequency is expressed as none, very rare, rare,

occasional, frequent, and very frequent. None means

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

unlikely but possible under extremely unusual weather

conditions (the chance of flooding is less than 1

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

under unusual weather conditions (the chance of

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

it occurs infrequently under normal weather conditions

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

frequent that it is likely to occur often under normal

weather conditions (the chance of flooding is more

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

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

likely to occur very often under normal weather

conditions (the chance of flooding is more than 50

percent in all months of any year).

The information is based on evidence in the soil

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

deposited by floodwater; irregular decrease in organic

matter content with increasing depth; and little or no

horizon development.

Also considered are local information about the

extent and levels of flooding and the relation of each

soil on the landscape to historic floods. Information on

the extent of flooding based on soil data is less

specific than that provided by detailed engineering

surveys that delineate flood-prone areas at specific

flood frequency levels.

Soil Features

Table 21 gives estimates of various soil features.

The estimates are used in land use planning that

involves engineering considerations.

Potential for frost action is the likelihood of upward

or lateral expansion of the soil caused by the formation

of segregated ice lenses (frost heave) and the

subsequent collapse of the soil and loss of strength on

thawing. Frost action occurs when moisture moves

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

density, permeability, content of organic matter, and

depth to the water table are the most important factors

considered in evaluating the potential for frost action. It

is assumed that the soil is not insulated by vegetation

or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in

winter are the most susceptible to frost action. Well

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

susceptible. Frost heave and low soil strength during

thawing cause damage to pavements and other rigid

structures.

Risk of corrosion pertains to potential soil-induced

electrochemical or chemical action that corrodes or

weakens uncoated steel or concrete. The rate of

corrosion of uncoated steel is related to such factors

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

electrical conductivity of the soil. The rate of corrosion

of concrete is based mainly on the sulfate and sodium

content, texture, moisture content, and acidity of the

soil. Special site examination and design may be

needed if the combination of factors results in a severe

hazard of corrosion. The steel or concrete in

installations that intersect soil boundaries or soil layers

is more susceptible to corrosion than the steel or

concrete in installations that are entirely within one

kind of soil or within one soil layer.

For uncoated steel, the risk of corrosion, expressed

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

class, total acidity, electrical resistivity near field

capacity, and electrical conductivity of the saturation

extract.

For concrete, the risk of corrosion also is expressed

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

acidity, and amount of sulfates in the saturation

extract.

85

The system of soil classification used by the

National Cooperative Soil Survey has six categories

(Soil Survey Staff, 1999 and 2003). Beginning with the

broadest, these categories are the order, suborder,

great group, subgroup, family, and series.

Classification is based on soil properties observed in

the field or inferred from those observations or from

laboratory measurements. Table 22 shows the

classification of the soils in the survey area. The

categories are defined in the following paragraphs.

ORDER. Twelve soil orders are recognized. The

differences among orders reflect the dominant soilforming processes and the degree of soil formation.

Each order is identified by a word ending in sol. An

example is Mollisol.

SUBORDER. Each order is divided into suborders

primarily on the basis of properties that influence soil

genesis and are important to plant growth or

properties that reflect the most important variables

within the orders. The last syllable in the name of a

suborder indicates the order. An example is Aquolls

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

GREAT GROUP. Each suborder is divided into

great groups on the basis of close similarities in kind,

arrangement, and degree of development of

pedogenic horizons; soil moisture and temperature

regimes; type of saturation; and base status. Each

great group is identified by the name of a suborder

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

example is Endoaquolls (Endo, meaning within, plus

aquoll, the suborder of the Mollisols that has an aquic

moisture regime).

SUBGROUP. Each great group has a typic

subgroup. Other subgroups are intergrades or

extragrades. The typic subgroup is the central concept

of the great group; it is not necessarily the most

extensive. Intergrades are transitions to other orders,

suborders, or great groups. Extragrades have some

properties that are not representative of the great

group but do not indicate transitions to any other

taxonomic class. Each subgroup is identified by one or

more adjectives preceding the name of the great

group. An example is Cumulic 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-silty, mixed, superactive, calcareous,

mesic Cumulic Endoaquolls.

SERIES. The series consists of soils within a

family that have horizons similar in color, texture,

structure, reaction, consistence, mineral and chemical

composition, and arrangement in the profile.

Soil Series and Their Morphology

In this section, each soil series recognized in the

survey area is described. Characteristics of the soil

and the material in which it formed are identified for

each series. A pedon, a small three-dimensional area

of soil, that is typical of the series in the survey area is

described. The detailed description of each soil

horizon follows standards in the “Soil Survey Manual”

(Soil Survey Division Staff, 1993). Many of the

technical terms used in the descriptions are defined

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

“Keys to Soil Taxonomy” (Soil Survey Staff, 2003).

Unless otherwise indicated, colors in the descriptions

are for moist soil. Following the pedon description is

the range of important characteristics of the soils in

the series.

Taxadjunct features: The representative pedon for the

Fairhaven series in Woodbury County, Iowa, is a

taxadjunct because the strongly contrasting

particle-size transition zone is 6 inches thick and

there is not enough clay difference to meet the

contrasting particle-size criteria defined for the

series. Also, the textures in the underlying material

are finer than those defined as the range for the

series.

This section relates the major factors of soil

formation to the soils in Woodbury County. It also

describes the major processes of soil formation.

Factors of Soil Formation

Soil is a natural body of mineral and organic

constituents that has formed over time through a

process of chemical and physical weathering and that

is influenced by climatic conditions. Five major factors

interact to influence the development a soil: (1) parent

material; (2) the climate under which the soils

developed; (3) the biological processes of plant and

animals in and on the soil; (4) relief, or topography;

and (5) the length of time the forces have acted on the

parent materials (Jenny, 1941). Human activities have

also had a significant effect on the formation of soils.

Climate and biological processes are the active

factors of soil genesis. They act on the parent material

that has accumulated through the weathering of rocks

and slowly change it into a natural body that has

genetically related horizons. The effects of climate and

biological processes are conditioned by relief. The

parent material also affects the kind of profile that can

be formed; in extreme cases, parent material can

determine the kind of profile that forms almost entirely.

Finally, time is needed for changing the parent material

into a soil. Usually, a long time is required for the

development of distinct horizons.

The factors of soil genesis are so closely

interrelated that few generalizations can be made

regarding the effect of any one factor unless

conditions are specified for the others.

Climate

The soils in Woodbury County formed under

variable climatic conditions. During the post-Carey

glaciation period, from about 13,000 to 10,500 years

ago, the climate in central Iowa was cool and the

vegetation was dominantly conifers. During the period

from 10,500 to 8,000 years ago, a warming trend took

place and the vegetation changed from conifers to

mixed forest dominated by hardwoods. Beginning

about 8,000 years ago, the climate became even

warmer and drier. Herbaceous prairie vegetation

became dominant. The forest-prairie transition of

central Iowa changed in post-glacial climate from

relatively dry prairie to more moist conditions. This

change may have taken place about 3,000 years ago.

The present climate is midcontinental subhumid.

Nearly uniform climate prevails throughout the

county. The influence of the general climate, however,

is modified by local conditions. Microclimates are a

result of topography and vegetation. For example, in

areas of Hamburg soils on the very steep bluffs, most

of the water runs off or infiltrates rapidly into the soil.

This characteristic results in a warmer, drier climate

than that of nearby less sloping areas. On south-facing

slopes the effect is similar. North- and east-facing

slopes tend to be cooler and moister than south-facing

slopes and are more likely to support natural stands of

trees. Low-lying or depressional areas of poorly

drained or very poorly drained soils are wetter and

colder than most areas around them.

The general climate has had an important overall

influence on the characteristics of the soils but has not

caused major differences among them. The local

climate differences influence the characteristics of the

soils and account for some of the differences in soils

within the same climatic region.

Weathering of the parent material by water and air

is activated by changes in temperature. As a result of

weathering, changes caused by both physical and

chemical actions take place. Rainfall has influenced

the formation of the soils through its effect on the

amount of leaching in soils and on the kinds of plants

that grow.

Some variations in plant and animal life are caused

by variations in temperature or by the action of other

climatic forces on the soil material. To that extent,

climate influences changes in soils that are brought

about by differences in plant and animal populations.

Living Organisms

Biological processes of plants and animals greatly

affect soil formation. Burrowing animals, worms,

crayfish, and micro-organisms, such as fungus,

actinomycetes, and bacteria, influence soil properties.

Formation of the Soils
138 Soil Survey of

Differences in the kinds of vegetation can commonly

cause marked differences in soil properties and

development. Human activities have greatly affected

soil properties since the settlement of Woodbury

County.

Burrowing animals, such as badgers and pocket

gophers, move large amounts of soil from the subsoil

to the soil surface. They are active in relatively small

areas. In most places in Woodbury County, the soils

appear undisturbed by burrowing animals. Earthworms

and soil insects have a widespread effect. Earthworms

move up and down in soils as soil moisture or

temperature changes. In most of the soil profiles

examined in the county, earthworms had moved

materials from one soil horizon to another.

Earthworms are beneficial in several ways. The worm

channels they leave improve soil aeration and the rate

of infiltration. Earthworm castings, except when they

are fresh, enhance the stability of soil aggregates

(Shipitalo and Protz, 1988).

Micro-organisms, such as bacteria and fungi,

modify plant residues into humus and release plant

nutrients. Individual genera of bacteria and fungi tend

to colonize and decompose specific plant residues

and to prefer specific soil temperature and moisture

states (Broder and Wagner, 1988). The diversity of

bacteria and fungi genera in a soil, however, ensures

that plant residues are continually being decomposed,

except when the soil is frozen.

Tall grasses were the dominant vegetation when

Woodbury County was settled. Trees grew in places,

mainly in steep areas within a few miles of the

Missouri River Valley and along streams. The thickest

stands were on north- and east-facing slopes.

Because grasses have many roots and tops that

decay, soils that formed on prairies typically have a

thicker, darker surface layer than that of the soils that

formed under trees. The organic matter in the soils

that formed under trees is derived principally from

fallen leaves. These soils generally are more acid than

the soils that formed under grasses. Monona and

Galva soils are typical prairie soils. The stands of trees

on these soils have not been in place long enough to

affect soil formation significantly.

Important soil changes took place when human

activities began in the settlement of the survey area.

Some had little effect on soil productivity, but others

had more dramatic results. Changes caused by water

erosion and drainage generally are the most

significant.

Breaking of the sod, removal of the protective

vegetative cover, and cultivation made the sloping

areas more susceptible to erosion. Surface runoff

increased, and the rate at which water moved into the

soil decreased. As a result, accelerated erosion has

removed part or all of the original surface layer of the

sloping soils and has reduced fertility and the content

of organic matter.

Erosion has not only changed the thickness and

organic matter content of the surface soil, it has also

changed the soil structure. Slightly eroded soils exhibit

mostly granular structure, but as erosion becomes

more pronounced, the soil develops subangular

structure and finally deteriorates to a cloddy,

structureless condition in areas that are severely

eroded.

Prior to recent human occupation and the

widespread denudation of the soil surface, the loesscovered area experienced periods of downcutting of

streams, healing over, sedimentation, and downcutting

again. This process was accelerated after agriculture

was established in the survey area. New gullies can

occur quickly, but it takes many years for the scars to

heal themselves.

Gullies develop in stages. These stages have been

described as channel erosion by downward scour,

headward erosion and enlargement, healing, and

stabilization. Generally, headward erosion is a process

of soil sloughing that works from the water course and

up the hillside, sometimes with costly results. Bridges,

roads that parallel streams and rivers, and driveways

and building sites are often threatened or damaged by

such erosion.

Soils that are not subject to erosion have shown

signs of compaction by heavy agricultural equipment.

Compaction destroys soil structure. When they are

wet, soils in compacted areas are subject to puddling

and are less permeable than the soils in areas where

traffic is managed properly.

In many low areas, dark soils have received lighter

colored, calcareous deposition. Rawles and Wilsey

soils formed in this recent alluvium. These soils show

the influence of human activity. They have strata of

light and dark materials that were washed from the

hillsides and deposited by floods. This erosion has

taken place since cultivation of the hillsides began.

Human activities have also done much to increase

soil productivity. Agricultural terraces (fig. 18), erosioncontrol structures, diversion ditches, and ponds are

being used in some places to control runoff and

erosion. Installing drainage ditches and levees has

helped to minimize the effects of flooding, lowered the

water table, and prevented the subsequent deposition

of alluvium. The application of commercial fertilizers

and lime has helped to correct deficiencies in plant

nutrients. As a result, large areas on flood plains and
Woodbury County, Iowa 139

in the uplands are now suitable for cultivation and are

more productive than they were in their natural state.

Topography

Topography refers to the lay of the land. The

topography of Woodbury County ranges from the

nearly level bottom land along the Missouri River

Valley flood plain in the west, to the steep angular

loess hills and bluffs at the juncture of the uplands and

the bottom land, to rolling hills in the east. The vertical

interval between the Missouri River Valley and the

loess-covered uplands generally ranges from 200 to

400 feet. The lowest part of the county is along the

Missouri River in the southwest corner of the county.

The highest level in the county, about 1,460 feet above

sea level, is in several places in the eastern half of the

county.

In addition to the Missouri River, the major rivers in

the county are the Little Sioux, the Maple, and the

Floyd Rivers. These rivers join with a network of

drainage ditches as they cross the Missouri River

bottom land before they outlet into the Missouri River.

The Missouri River Valley currently has an extensive

network of field surface drains and drainage ditches

that connect with the major drainage ditches. This

drainage network has changed the use and

management of the Old Bottom Land area and has

made farming possible. This area had not been farmed

previously because it was too wet or was subject to

frequent flooding.

In Woodbury County, the slope ranges from nearly

level to very steep. Relief is an important factor in soil

formation because it affects drainage, runoff, the depth

to the water table, and erosion and sedimentation. A

difference in topography is the basic reason for the

differing soil properties of some of the soils in the

county.

Topography influences soils that formed in similar

parent material, as evidenced by the soil colors, the

Figure 18.—Terraces conserve topsoil and reduce the runoff rate in this area of Monona and Ida soils. Ida silt loam, 9 to 14 percent

slopes, severely eroded, is in the foreground. Monona silty clay loam, 5 to 9 percent slopes, moderately eroded, is in the

background. The Monona soil is on summits and the upper side slopes, and the Ida soil is on the steeper parts of side slopes.
140 Soil Survey of

thickness of the solum, and the horizonation of the

soils. Ida and Monona soils are examples of soils that

formed in similar parent material but differ in

characteristics mainly related to relief. Some water

runs off the well drained, sloping Monona soils, but

more water runs off the more strongly sloping Ida

soils. Water has eroded the Ida soils at such a rate

that little development has taken place. The surface

layer of the Monona soils is thicker and darker than

that of the Ida soils and is leached of carbonates,

whereas Ida soils are calcareous at or near the

surface. Slope also affects the thickness of the solum.

The steeper and more convex the slope, the thinner

the solum.

Relief affects the color of the B horizon through its

effect on drainage and soil aeration. The subsoil of a

soil that has good drainage generally is brown

because iron compounds are oxidized and are well

distributed throughout the horizon. Conversely, the

subsoil of soils that have restricted drainage generally

is grayish and mottled. The subsoil of the low-lying,

poorly drained and very poorly drained, clayey Luton

soils on the Missouri River Old Bottom Land, for

example, is gray and olive gray. In contrast, the Keg

soils, which are at a slightly higher elevation, are well

drained and have a brownish subsoil.

Parent Material

The soils in Woodbury County formed in three main

types of parent material. These are loess, alluvium,

and till.

Loess is the most extensive parent material in the

county. It is a yellowish brown, wind-deposited material

that consists mainly of silt particles and small amounts

of clay and sand. Small calcium carbonate concretions

also are common in the unleached loess. Most of the

upland soils formed in Wisconsin loess. Ida and

Monona soils are the most extensive of these.

Hamburg soils are on bluffs adjacent to the

Missouri River Valley. The loess is thickest on the

bluffs and becomes thinner toward the east. It ranges

from about 200 feet thick at the bluffs on the western

side of the county to less than 50 feet thick on the

eastern side of the county. In the northeast corner of

the county, where Galva soils occur, the thickness of

the loess is about 10 feet.

Alluvium is the second most extensive parent

material in the county. The largest area is in the

Missouri River Valley. Alluvium consists of sediment

deposited along major streams and narrow upland

drainageways and on low terraces. It varies in texture

because of the manner in which it was deposited and

can range from sandy to clayey.

The soils that formed in alluvium are in two broad

categories. One group formed in alluvium that has

been in place long enough to have been affected by

the soil-forming processes. Examples are Blencoe,

Cooper, Keg, Lakeport, Luton, Salix, and Zook soils.

The second group formed in recent alluvium.

Examples are Albaton, Blake, Haynie, Onawa, Sarpy,

and Wilsey soils. Because of the accumulation of

organic matter, the first group is darker in the upper

part than the second group and is darker to a greater

depth.

The texture of the soils that formed in alluvium

varies widely. Albaton and Luton soils formed entirely

in clayey alluvium; Sarpy soils are loamy and sandy

throughout. Haynie, Keg, Kennebec, and Wilsey soils

are dominantly silt loam throughout. Lakeport and

Smithland soils are dominantly silty clay loam

throughout. Some soils have layers of different

textures. Examples are Blencoe, Blake, Modale,

Onawa, and Percival soils.

Local alluvium has been transported only short

distances and retains the characteristics of the

parent material of the soil from which it was

transported, either by wind or water or both. Napier

soils are examples of soils that formed in local

alluvium. They are generally at the base of slopes,

lower than the soils that formed in loess. Castana soils

formed partly in colluvium that was moved downslope

by gravity. All of the soils at the base of slopes have

textures similar to those of the adjacent soils on

hillsides.

Till is the least extensive parent material in the

county. It is a grayish brown to yellowish brown,

calcareous material that was deposited by glacial ice.

It consists of nearly equal amounts of sand, silt, and

clay with variable amounts of rock fragments ranging

from very fine gravel to boulders. Soils that formed in

till have a higher bulk density, slower permeability, and

a lower cation-exchange capacity than the adjacent

loess soils. Burchard and Liston soils formed in till.

They are on very steep side slopes and nose slopes,

where the loess surface has been removed by

geologic erosion and the till is exposed.

Time

The length of time that the soil material is acted on

by soil-forming processes affects the kind of soil that

forms. The older soils have strongly expressed genetic

horizons. Luton and Monona soils are examples.

Some soils show little or no evidence of development

because they have not been in place long enough for

the formation of distinct horizons. Albaton and Wilsey

soils are examples.
Woodbury County, Iowa 141

An older soil generally has a higher content of clay

in the subsoil than a younger soil that formed in similar

kinds of parent material. As a soil forms, clay is moved

from the surface layer to the subsoil. This transfer

increases the content of clay in the subsoil. The

process is more evident in nearly level soils than in the

more sloping soils.

In the steeper areas, the soil material is generally

removed before enough time has passed for the

development of a thick profile that has distinct

horizons. Even if the soil material has been in place a

long time, the soil can exhibit little development

because much of the water runs off the slopes rather

than through the soil material.

Processes of Soil Formation

Horizons are differentiated from each other when

four basic kinds of change take place. These are

additions, removals, transfers, and transformations.

Each of these kinds of change affects many

substances in the soils, such as organic matter,

soluble salts, carbonates, sesquioxides, and silicate

clay materials. Most of these processes tend to

promote horizon differentiation, but some tend to offset

or retard it.

The processes and the resulting changes occur

simultaneously in soils. The ultimate nature of the

profile is governed by the balance of these changes

within the soil.

An accumulation of organic matter generally is an

early phase of horizon differentiation. It has been an

important process in the differentiation of horizons in

the soils of Woodbury County. The amount of organic

matter that has accumulated in the surface layer of the

soils ranges from high to very low. In some soils the

content of organic matter formerly was fairly high but

is now low because of erosion.

The removal of substances from parts of the soil

profile is important in the differentiation of horizons.

The downward movement of calcium carbonates and

bases is an example. The upper part of the soils in

Woodbury County has been leached of calcium

carbonate. Many soils have been so strongly leached

that they are strongly acid or very strongly acid even in

the subsoil.

Phosphorus is removed from the subsoil by plant

roots and transferred to the parts of the plant growing

above the ground. It is then returned to the surface

layer in the plant residue. This process affects the form

and distribution of phosphorus in the profile.

The translocation of silicate clay minerals is another

important process. The clay minerals in the surface

layer are carried downward in suspension by

percolating water. They accumulate in the subsoil as

fillings in pores and root channels and as clay films.

This process has affected many of the soils in the

county. In other soils, however, the clay content of the

surface layer is not markedly different from that of the

underlying layer and other evidence of clay movement

is minimal.

Another kind of transfer occurs when cracks form

as a result of shrinking and swelling. Because of the

cracks, some of the material from the surface layer is

transferred to the lower parts of the profile. This

transfer is minimal in most soils. It is most common in

very clayey soils. It can occur in Luton and Tieville

soils.

Transformations are physical and chemical. The

weathering of soil particles to smaller sizes is an

example of transformation. The reduction of iron is

another example. This process is called gleying. It

occurs when the soil is saturated for long periods. The

soil contains enough organic matter for biological

activity to take place during periods of saturation.

Gleying is evidenced by ferrous iron and gray colors in

the soil. It is characteristic of poorly drained soils. The

content of reductive extractable iron, or free iron,

generally is lower in somewhat poorly drained soils.

Another kind of transformation is the weathering of the

primary apatite minerals in the parent material to

secondary phosphorus compounds.

“National Soil Survey Handbook” (available in local

offices of the Natural Resources Conservation Service

or on the Internet).

Ablation till. Loose, relatively permeable earthy

material deposited during the downwasting of

nearly static glacial ice, either contained within or

accumulated on the surface of the glacier.

Aeration, soil. The exchange of air in soil with air from

the atmosphere. The air in a well aerated soil is

similar to that in the atmosphere; the air in a

poorly aerated soil is considerably higher in

carbon dioxide and lower in oxygen.

Aggregate, soil. Many fine particles held in a single

mass or cluster. Natural soil aggregates, such as

granules, blocks, or prisms, are called peds. Clods

are aggregates produced by tillage or logging.

sand, silt, clay, and various mixtures of these,

deposited on land by running water.

Alpha,alpha-dipyridyl. A compound that when

dissolved in ammonium acetate is used to detect

the presence of reduced iron (Fe II) in the soil. A

positive reaction implies reducing conditions and

the likely presence of redoximorphic features.

areas geographically associated in a characteristic

repeating pattern and defined and delineated as a

single map unit.

Available water capacity (available moisture

capacity). The capacity of soils to hold water

available for use by most plants. It is commonly

defined as the difference between the amount of

soil water at field moisture capacity and the

amount at wilting point. It is commonly expressed

as inches of water per inch of soil. The capacity, in

inches, in a 60-inch profile or to a limiting layer is

expressed as:

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

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

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

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

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

Backslope. The position that forms the steepest

and generally linear, middle portion of a hillslope

(fig. 19). In profile, backslopes are commonly

bounded by a convex shoulder above and a

concave footslope below.

cation-exchange properties is saturated with

exchangeable bases (sum of Ca, Mg, Na, and K),

expressed as a percentage of the total cationexchange capacity.

Base slope (geomorphology). A geomorphic

component of hills (fig. 19) consisting of the

concave to linear (perpendicular to the contour)

slope that, regardless of the lateral shape, forms

an apron or wedge at the bottom of a hillside

dominated by colluvium and slope-wash

sediments (for example, slope alluvium).

Beach deposits. Material, such as sand and gravel,

that is generally laid down parallel to an active or

relict shoreline of a post-glacial or glacial lake.

Bedding plane. A planar or nearly planar bedding

surface that visibly separates each successive

in particle size, or various combinations of these.

The term is commonly applied to any bedding

surface, even one that is conspicuously bent or

deformed by folding.

Bedrock. The solid rock that underlies the soil and

Glossary

the configuration and relief of the landforms are

determined or strongly influenced by the

underlying bedrock.

earth constructed on or nearly on a contour,

supported by a barrier of rocks or similar material,

and designed to make the soil suitable for tillage

and to prevent accelerated erosion.

Bisequum. Two sequences of soil horizons, each of

which consists of an illuvial horizon and the

overlying eluvial horizons.

Blowout. A saucer-, cup-, or trough-shaped

depression formed by wind erosion on a

preexisting dune or other sand deposit, especially

centimeters) in diameter.

Brush management. Use of mechanical, chemical, or

biological methods to make conditions favorable

increases forage production and thus reduces the

hazard of erosion. It can improve the habitat for

some species of wildlife.

carbonate (commonly combined with magnesium

carbonate) to effervesce visibly when treated with

cold, dilute hydrochloric acid.

Canopy. The leafy crown of trees or shrubs. (See

Crown.)

Capillary water. Water held as a film around soil

particles and in tiny spaces between particles.

Surface tension is the adhesive force that holds

capillary water in the soil.

Catena. A sequence, or “chain,” of soils on a

landscape that formed in similar kinds of parent

Cation-exchange capacity. The total amount of

exchangeable cations that can be held by the soil,

expressed in terms of milliequivalents per 100

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

other stated pH value. The term, as applied to

soils, is synonymous with base-exchange capacity

but is more precise in meaning.

centimeters) in diameter.

Cobbly soil material. Material that has 15 to 35

percent, by volume, rounded or partially rounded

rock fragments 3 to 10 inches (7.6 to 25

centimeters) in diameter. Very cobbly soil material

has 35 to 60 percent of these rock fragments, and

extremely cobbly soil material has more than 60

percent.

Colluvium. Unconsolidated, unsorted earth material

being transported or deposited on side slopes

and/or at the base of slopes by mass movement

(e.g., direct gravitational action) and by local,

unconcentrated runoff.

or establishing terraces, diversions, and other

water-control structures on a complex slope is

difficult.

Complex, soil. A map unit of two or more kinds of soil

or miscellaneous areas in such an intricate pattern

them separately at the selected scale of mapping.

The pattern and proportion of the soils or

miscellaneous areas are somewhat similar in all

areas.

Concretions. See Redoximorphic features.

Conservation cropping system. Growing crops in

combination with needed cultural and

management practices. In a good conservation

cropping system, the soil-improving crops and

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

are needed on all tilled soils. Soil-improving

practices in a conservation cropping system

include the use of rotations that contain grasses

and legumes and the return of crop residue to the

soil. Other practices include the use of green

manure crops of grasses and legumes, proper

tillage, adequate fertilization, and weed and pest

control.

Conservation tillage. A tillage system that does not

invert the soil and that leaves a protective amount

of crop residue on the surface throughout the year.

and adhesion of soil material and its resistance to

deformation when ruptured. Consistence includes

resistance of soil material to rupture and to

penetration; plasticity, toughness, and stickiness of

puddled soil material; and the manner in which the

soil material behaves when subject to

compression. Terms describing consistence are

defined in the “Soil Survey Manual.”

Contour stripcropping. Growing crops in strips that

follow the contour. Strips of grass or close-growing

crops are alternated with strips of clean-tilled

crops or summer fallow.

Control section. The part of the soil on which

classification is based. The thickness varies

among different kinds of soil, but for many it is that

part of the soil profile between depths of 10 inches

and 40 or 80 inches.

Coprogenous earth (sedimentary peat). A type of

limnic layer composed predominantly of fecal

material derived from aquatic animals.

Corrosion (geomorphology). A process of erosion

whereby rocks and soil are removed or worn away

by natural chemical processes, especially by the
148 Soil Survey of

solvent action of running water, but also by other

reactions, such as hydrolysis, hydration,

carbonation, and oxidation.

Corrosion (soil survey interpretations). Soil-induced

electrochemical or chemical action that dissolves

or weakens concrete or uncoated steel.

Cover crop. A close-growing crop grown primarily to

improve and protect the soil between periods of

regular crop production, or a crop grown between

trees and vines in orchards and vineyards.

Crop residue management. Returning crop residue

to the soil, which helps to maintain soil structure,

organic matter content, and fertility and helps to

control erosion.

Cropping system. Growing crops according to a

planned system of rotation and management

practices.

Cross-slope farming. Deliberately conducting

farming operations on sloping farmland in such a

way that tillage is across the general slope.

Crown. The upper part of a tree or shrub, including the

living branches and their foliage.

Culmination of the mean annual increment (CMAI).

The average annual increase per acre in the

volume of a stand. Computed by dividing the total

volume of the stand by its age. As the stand

increases in age, the mean annual increment

continues to increase until mortality begins to

reduce the rate of increase. The point where the

stand reaches its maximum annual rate of growth

is called the culmination of the mean annual

increment.

Cutbanks cave (in tables). The walls of excavations

tend to cave in or slough.

Deferred grazing. Postponing grazing or resting

grazing land for a prescribed period.

Delta. A body of alluvium having a surface that is fan

shaped and nearly flat; deposited at or near the

mouth of a river or stream where it enters a body

of relatively quiet water, generally a sea or lake.

Dense layer (in tables). A very firm, massive layer that

has a bulk density of more than 1.8 grams per

cubic centimeter. Such a layer affects the ease of

digging and can affect filling and compacting.

bedrock. Very deep soils are more than 60 inches

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

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

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

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

generally a terrace, built to protect downslope

areas by diverting runoff from its natural course.

Divide. (a) The line of separation, or (b) the summit

area, or narrow tract of higher ground that

constitutes the watershed boundary between two

adjacent drainage basins (fig. 19); it divides the

surface waters that flow naturally in one direction

from those that flow in the opposite direction.

Drainage class (natural). Refers to the frequency and

duration of wet periods under conditions similar to

those under which the soil formed. Alterations of

the water regime by human activities, either

through drainage or irrigation, are not a

consideration unless they have significantly

changed the morphology of the soil. Seven

classes of natural soil drainage are recognized—

excessively drained, somewhat excessively

drained, well drained, moderately well drained,

somewhat poorly drained, poorly drained, and

very poorly drained. These classes are defined in

the “Soil Survey Manual.”

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

from an area.

Drift. A general term applied to all mineral material

(clay, silt, sand, gravel, and boulders) transported

by a glacier and deposited directly by or from the

ice or transported by running water emanating

from a glacier. Drift includes unstratified material

(till) that forms moraines and stratified deposits

that form outwash plains, eskers, kames, varves,

and glaciofluvial sediments. The term is generally

applied to Pleistocene glacial deposits in areas

that no longer contain glaciers.

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.

Duff. A generally firm organic layer on the surface of

mineral soils. It consists of fallen plant material

that is in the process of decomposition and

includes everything from the litter on the surface to

underlying pure humus.

Earthy fill. See Mine spoil.

Eluviation. The movement of material in true solution

or colloidal suspension from one place to another

within the soil. Soil horizons that have lost material

through eluviation are eluvial; those that have

received material are illuvial.

Endosaturation. A type of saturation of the soil in

which all horizons between the upper boundary of

saturation and a depth of 2 meters are saturated.

Eolian deposit. Sand-, silt-, or clay-sized clastic
Woodbury County, Iowa 149

material transported and deposited primarily by

wind, commonly in the form of a dune or a sheet

of sand or loess.

that flows only in direct response to precipitation. It

receives no long-continued supply from melting

snow or other source, and its channel is above the

water table at all times.

Episaturation. A type of saturation indicating a

perched water table in a soil in which saturated

layers are underlain by one or more unsaturated

layers within 2 meters of the surface.

Erosion. The wearing away of the land surface by

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

such processes as gravitational creep.

Erosion (geologic). Erosion caused by geologic

processes acting over long geologic periods and

resulting in the wearing away of mountains and

the building up of such landscape features as

flood plains and coastal plains. Synonym: natural

erosion.

Erosion (accelerated). Erosion much more rapid

than geologic erosion, mainly as a result of human

or animal activities or of a catastrophe in nature,

such as a fire, that exposes the surface.

Erosion pavement. A surficial lag concentration or

layer of gravel and other rock fragments that

remains on the soil surface after sheet or rill

erosion or wind has removed the finer soil

particles and that tends to protect the underlying

soil from further erosion.

Escarpment. A relatively continuous and steep slope

or cliff breaking the general continuity of more

gently sloping land surfaces and resulting from

erosion or faulting. Most commonly applied to cliffs

produced by differential erosion. Synonym: scarp.

Esker. A long, narrow, sinuous, steep-sided ridge of

stratified sand and gravel deposited as the bed of

a stream flowing in an ice tunnel within or below

the ice (subglacial) or between ice walls on top of

the ice of a wasting glacier and left behind as high

ground when the ice melted. Eskers range in

length from less than a kilometer to more than 160

kilometers and in height from 3 to 30 meters.

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

plant nutrients, in adequate amounts and in proper

balance, for the growth of specified plants when

light, moisture, temperature, tilth, and other growth

factors are favorable.

Fibric soil material (peat). The least decomposed of

all organic soil material. Peat contains a large

amount of well preserved fiber that is readily

identifiable according to botanical origin. Peat has

the lowest bulk density and the highest water

content at saturation of all organic soil material.

Field moisture capacity. The moisture content of a

soil, expressed as a percentage of the ovendry

weight, after the gravitational, or free, water has

drained away; the field moisture content 2 or 3

days after a soaking rain; also called normal field

capacity, normal moisture capacity, or capillary

capacity.

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

First bottom. An obsolete, informal term loosely

applied to the lowest flood-plain steps that are

subject to regular flooding.

slate, shale, or (rarely) schist 6 to 15 inches (15 to

38 centimeters) long.

Flood plain. The nearly level plain that borders a

stream and is subject to flooding unless protected

artificially.

Flood-plain landforms. A variety of constructional

and erosional features produced by stream

channel migration and flooding. Examples include

backswamps, flood-plain splays, meanders,

meander belts, meander scrolls, oxbow lakes, and

natural levees.

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

outspread deposit formed where an overloaded

stream breaks through a levee (natural or artificial)

and deposits its material (commonly coarse

grained) on the flood plain.

Flood-plain step. An essentially flat, terrace-like

alluvial surface within a valley that is frequently

covered by floodwater from the present stream;

any approximately horizontal surface still actively

modified by fluvial scour and/or deposition. May

occur individually or as a series of steps.

Fluvial. Of or pertaining to rivers or streams; produced

by stream or river action.

Footslope. The concave surface at the base of a

hillslope (fig. 19). A footslope is a transition zone

between upslope sites of erosion and transport

(shoulders and backslopes) and downslope sites

of deposition (toeslopes).

Forb. Any herbaceous plant not a grass or a sedge.

Fragipan. A loamy, brittle subsurface horizon low in

porosity and content of organic matter and low or

moderate in clay but high in silt or very fine sand.

A fragipan appears cemented and restricts roots.
150 Soil Survey of

When dry, it is hard or very hard and has a higher

bulk density than the horizon or horizons above.

When moist, it tends to rupture suddenly under

pressure rather than to deform slowly.

Genesis, soil. The mode of origin of the soil. Refers

especially to the processes or soil-forming factors

responsible for the formation of the solum, or true

soil, from the unconsolidated parent material.

Glaciofluvial deposits. Material moved by glaciers

and subsequently sorted and deposited by

streams flowing from the melting ice. The deposits

are stratified and occur in the form of outwash

plains, valley trains, deltas, kames, eskers, and

kame terraces.

Glaciolacustrine deposits. Material ranging from fine

clay to sand derived from glaciers and deposited

in glacial lakes mainly by glacial meltwater. Many

deposits are bedded or laminated.

Gleyed soil. Soil that formed under poor drainage,

resulting in the reduction of iron and other

elements in the profile and in gray colors.

Graded stripcropping. Growing crops in strips that

grade toward a protected waterway.

Grassed waterway. A natural or constructed

waterway, typically broad and shallow, seeded to

grass as protection against erosion. Conducts

surface water away from cropland.

much as 3 inches (2 millimeters to 7.6

centimeters) in diameter. An individual piece is a

pebble.

Gravelly soil material. Material that has 15 to 35

percent, by volume, rounded or angular rock

fragments, not prominently flattened, as much as

3 inches (7.6 centimeters) in diameter.

Green manure crop (agronomy). A soil-improving

crop grown to be plowed under in an early stage

of maturity or soon after maturity.

Ground water. Water filling all the unblocked pores of

the material below the water table.

Gully. A small channel with steep sides caused by

erosion and cut in unconsolidated materials by

concentrated but intermittent flow of water. The

distinction between a gully and a rill is one of

depth. A gully generally is an obstacle to farm

machinery and is too deep to be obliterated by

ordinary tillage; a rill is of lesser depth and can be

smoothed over by ordinary tillage.

Hard bedrock. Bedrock that cannot be excavated

except by blasting or by the use of special

equipment that is not commonly used in

construction.

Hard to reclaim (in tables). Reclamation is difficult

after the removal of soil for construction and other

uses. Revegetation and erosion control are

extremely difficult.

Hardpan. A hardened or cemented soil horizon, or

layer. The soil material is sandy, loamy, or clayey

and is cemented by iron oxide, silica, calcium

carbonate, or other substance.

Head slope (geomorphology). A geomorphic

component of hills consisting of a laterally

concave area of a hillside, especially at the head

of a drainageway (fig. 19). The overland waterflow

is converging.

Hemic soil material (mucky peat). Organic soil

material intermediate in degree of decomposition

between the less decomposed fibric material and

the more decomposed sapric material.

High-residue crops. Such crops as small grain and

corn used for grain. If properly managed, residue

from these crops can be used to control erosion

until the next crop in the rotation is established.

These crops return large amounts of organic

matter to the soil.

Hill. A generic term for an elevated area of the land

surface, rising as much as 1,000 feet above

surrounding lowlands, commonly of limited summit

area and having a well defined outline. Slopes are

generally more than 15 percent. The distinction

between a hill and a mountain is arbitrary and may

depend on local usage.

Hillslope. A generic term for the steeper part of a

hill between its summit and the drainage line,

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

(fig. 19).

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

the surface, having distinct characteristics

produced by soil-forming processes. In the

identification of soil horizons, an uppercase letter

represents the major horizons. Numbers or

lowercase letters that follow represent

subdivisions of the major horizons. An explanation

of the subdivisions is given in the “Soil Survey

Manual.” The major horizons of mineral soil are as

follows:

O horizon.—An organic layer of fresh and

decaying plant residue.

L horizon.—A layer of organic and mineral limnic

materials, including coprogenous earth

(sedimentary peat), diatomaceous earth, and

marl.

A horizon.—The mineral horizon at or near the

surface in which an accumulation of humified

organic matter is mixed with the mineral material.

Also, a plowed surface horizon, most of which was

originally part of a B horizon.

E horizon.—The mineral horizon in which the main
Woodbury County, Iowa 151

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.

Igneous rock. Rock that was formed by cooling and

solidification of magma and that has not been

changed appreciably by weathering since its

formation. Major varieties include plutonic and

volcanic rock (e.g., andesite, basalt, and granite).

Illuviation. The movement of soil material from one

horizon to another in the soil profile. Generally,

material is removed from an upper horizon and

deposited in a lower horizon.

Impervious soil. A soil through which water, air, or

roots penetrate slowly or not at all. No soil is

absolutely impervious to air and water all the time.

Infiltration. The downward entry of water into the

immediate surface of soil or other material, as

contrasted with percolation, which is movement of

water through soil layers or material.

Infiltration capacity. The maximum rate at which

water can infiltrate into a soil under a given set of

conditions.

Infiltration rate. The rate at which water penetrates

the surface of the soil at any given instant, usually

expressed in inches per hour. The rate can be

limited by the infiltration capacity of the soil or the

rate at which water is applied at the surface.

Intake rate. The average rate of water entering the

soil under irrigation. Most soils have a fast initial

rate; the rate decreases with application time.

Therefore, intake rate for design purposes is not a

constant but is a variable depending on the net

irrigation application. The rate of water intake, in

inches per hour, is expressed as follows:

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

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

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

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

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

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

More than 2.5 ............................................. very high

Interfluve. A landform composed of the relatively

undissected upland or ridge between two adjacent

valleys containing streams flowing in the same

general direction. An elevated area between two

drainageways that sheds water to those

drainageways.

Interfluve (geomorphology). A geomorphic

component of hills consisting of the uppermost,

comparatively level or gently sloping area of a hill

(fig. 19); shoulders of backwearing hillslopes can

narrow the upland or can merge, resulting in a

strongly convex shape.

Intermittent stream. A stream, or reach of a stream,

that does not flow year-round but that is commonly

dry for 3 or more months out of 12 and whose

channel is generally below the local water table. It

flows only during wet periods or when it receives

ground-water discharge or long, continued

contributions from melting snow or other surface

and shallow subsurface sources.

Iron depletions. See Redoximorphic features.

Irrigation. Application of water to soils to assist in

production of crops. Methods of irrigation are:

Basin.—Water is applied rapidly to nearly level

plains surrounded by levees or dikes.

Border.—Water is applied at the upper end of a

strip in which the lateral flow of water is controlled

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 ironmanganese 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).

concentration) that formerly was draped across a

topographic surface and was later buried by

additional sediments. A stone line generally caps

formation, and erosion before burial. Many stone

lines seem to be buried erosion pavements,

originally formed by sheet and rill erosion across

deposition.

Taxadjuncts. Soils that cannot be classified in a

series recognized in the classification system.

Such soils are named for a series they strongly

resemble and are designated as taxadjuncts to

that series because they differ in ways too small to

behavior. Soils are recognized as taxadjuncts only

when one or more of their characteristics are

slightly outside the range defined for the family of

the series for which the soils are named.

other types of drift.

Terrace (conservation). An embankment, or ridge,

constructed across sloping soils on the contour or

at a slight angle to the contour. The terrace

intercepts surface runoff so that water soaks into

the soil or flows slowly to a prepared outlet. A

terrace in a field generally is built so that the field

can be farmed. A terrace intended mainly for

drainage has a deep channel that is maintained in

permanent sod.

Terrace (geomorphology). A steplike surface,

bordering a valley floor or shoreline, that

represents the former position of a flood plain,

lake, or seashore. The term is usually applied both

to the relatively flat summit surface (tread) that

was cut or built by stream or wave action and to

the steeper descending slope (scarp or riser) that

has graded to a lower base level of erosion.

Terracettes. Small, irregular steplike forms on steep

hillslopes, especially in pasture, formed by creep

or erosion of surficial materials that may be

induced or enhanced by trampling of livestock,

such as sheep or cattle.

Texture, soil. The relative proportions of sand, silt,

and clay particles in a mass of soil. The basic

textural classes, in order of increasing proportion
Woodbury County, Iowa 159

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.”

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 (fig. 19). 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 closeddepression floors.

Topsoil. The upper part of the soil, which is the most

favorable material for plant growth. It is ordinarily

rich in organic matter and is used to topdress

roadbanks, lawns, and land affected by mining.

Trace elements. Chemical elements, for example,

zinc, cobalt, manganese, copper, and iron, in soils

in extremely small amounts. They are essential to

plant growth.

Tread. The flat to gently sloping, topmost, laterally

extensive slope of terraces, flood-plain steps, or

other stepped landforms; commonly a recurring

part of a series of natural steplike landforms, such

as successive stream terraces.

Upland. An informal, general term for the higher

ground of a region, in contrast with a low-lying

adjacent area, such as a valley or plain, or for land

at a higher elevation than the flood plain or low

stream terrace; land above the footslope zone of

the hillslope continuum.

Valley fill. The unconsolidated sediment deposited by

any agent (water, wind, ice, or mass wasting) so

as to fill or partly fill a valley.

Variegation. Refers to patterns of contrasting

colors assumed to be inherited from the parent

material rather than to be the result of poor

drainage.

Varve. A sedimentary layer or a lamina or sequence of

laminae deposited in a body of still water within a

year. Specifically, a thin pair of graded

glaciolacustrine layers seasonally deposited,

usually by meltwater streams, in a glacial lake or

other body of still water in front of a glacier.

Water bars. Smooth, shallow ditches or depressional

areas that are excavated at an angle across a

sloping road. They are used to reduce the

downward velocity of water and divert it off and

away from the road surface. Water bars can easily

be driven over if constructed properly.

Weathering. All physical disintegration, chemical

decomposition, and biologically induced changes

in rocks or other deposits at or near the earth’s

surface by atmospheric or biologic agents or by

circulating surface waters but involving essentially

no transport of the altered material.

Well graded. Refers to soil material consisting of

coarse grained particles that are well distributed

over a wide range in size or diameter. Such soil

normally can be easily increased in density and

bearing properties by compaction. Contrasts with

poorly graded soil.

Wilting point (or permanent wilting point). The

moisture content of soil, on an ovendry basis, at

which a plant (specifically a sunflower) wilts so

much that it does not recover when placed in a

humid, dark chamber.

 * A growing degree day is a unit of heat available for plant growth. It can be calculated by adding the

maximum and minimum daily temperatures, dividing the sum by 2, and subtracting the temperature below which

growth is minimal for the principal crops in the area (50 degrees F).

 need for onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The

 larger the value, the greater the limitation. "Not rated" indicates that data are not

 available or that no rating is applicable. See text for further explanation of ratings in

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

 need for onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The

 larger the value, the greater the limitation. "Not rated" indicates that data are not

 available or that no rating is applicable. See text for further explanation of ratings in

 this table)

Table 14a.--Construction Materials

(The information in this table indicates the dominant soil condition but

 does not eliminate the need for onsite investigation. The ratings

 given for the thickest layer are for the thickest layer above and

 excluding the bottom layer. The numbers in the value columns range

 from 0.00 to 0.99. The greater the value, the greater the

 likelihood that the bottom layer or thickest layer of the soil is

 a source of sand or gravel. "Not rated" indicates that data are not

 available or that no rating is applicable. See text for further

 explanation of ratings in this table)

 need for onsite investigation. The numbers in the value columns range from 0.01 to 1.00. The

 larger the value, the greater the limitation. "Not rated" indicates that data are not

 available or that no rating is applicable. See text for further explanation of ratings in
