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

Soil Survey of Howard County, Maryland

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 2001. Soil names and

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

publication refer to conditions in the survey area in 2003. The most current official data

are available at http://websoilsurvey.nrcs.usda.gov/app/. This survey was made

cooperatively by the Natural Resources Conservation Service, the Maryland

Agricultural Experiment Station (University of Maryland), the Maryland Department of

Agriculture, the Howard County Board of Commissioners, and the Howard County Soil

Conservation District. The survey is part of the technical assistance furnished to the

Howard County Soil Conservation District.

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: Top left—Typical view of the Patapsco River valley along the Howard and Baltimore County

line. This area provides opportunities for a variety of recreational activities, including fishing, hiking,

and biking. Codorus and Hatboro soils are on the flood plain along the river, and Manor, Bannertown,

Legore, and Relay soils are on the adjacent uplands. Top right—One of the many parks near

Columbia, Maryland, that provides recreational opportunities for the rapidly developing community.

Bottom—Typical land use change from agriculture to a mixture of horse farms and suburban

development. Many areas of prime farmland are taken out of production each year because of urban

sprawl from Baltimore and Washington, D.C.

Soil Survey of Howard County, Maryland

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

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

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

impact of selected land uses on the environment.

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

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

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

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

use, select sites for construction, and identify special practices needed to ensure

proper performance. Conservationists, teachers, students, and specialists in

recreation, wildlife management, waste disposal, and pollution control can use the

survey to help them understand, protect, and enhance the environment.

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

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

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

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

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

landowner or user is responsible for identifying and complying with existing laws and

regulations.

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

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

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

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

poorly suited to basements or underground installations.

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

survey. 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.

Information on specific uses is given for each soil. 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.

Soil Survey of Howard County, Maryland

HOWARD COUNTY is in the central part of Maryland (fig. 1). It encompasses

162,100 acres, or 253 square miles, making it the second smallest county in the

State. It is bordered by the Patapsco River to the north, the Patuxent River to the

south, and Deep Run to the east. The counties adjacent to Howard County are

Frederick County to the northwest, Carroll County to the north, Baltimore County to

the northeast, and Montgomery, Prince Georges, and Anne Arundel Counties to the

south. Ellicott City, the county seat, is about 10 miles from Baltimore and 30 miles

from Washington, D.C.

General Nature of the County

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

history and development, industry and transportation, water supply, geology and

associated soils, agriculture, mineral resources, and climate.

History and

Development

Howard County was

named after John Eager

Howard, who served as an

officer in the American

Revolutionary War and

later as the Governor of

Maryland. Originally part

of Anne Arundel County,

the area was included as

part of Baltimore County

from 1698 to 1727, when it once again became part of Anne Arundel County. It was

established as an independent jurisdiction in 1851.

The Elkridge Landing was originally established as a port of entry along the

Patapsco River in the early 1700s. It was one of the earliest establishments of Upper

Anne Arundel, the area later named Howard County. This landing soon rivaled

Annapolis as a seaport due to its proximity to well established estates in Baltimore

and Anne Arundel Counties, as well as to the settlers that lived west of Elkridge. In

1774, a tobacco warehouse was established at the landing, at which more than half

of the tobacco grown in Anne Arundel County was inspected. Primary exports to

England from this port included tobacco and iron that was mined along the Patapsco

River.

About 1774, the Ellicott brothers from Bucks County, Pennsylvania, established the

area’s only, and the Nation’s most technologically advanced, gristmills. With this

success, Ellicott’s Mills, which later was renamed Ellicott City, became the center of

activity in Upper Anne Arundel. Agriculture began to shift from tobacco to more

diverse practices that focused primarily on wheat and other small grain. Farmers in

the region also began applying lime and fertilizer to the farmland.

The growing economy afforded the development of improved transportation.

Frederick Pike was built to connect the cities of Baltimore and Wheeling, West

Virginia. Route 1 was continually being widened to handle the growing shipment of

goods and increased travel between major cities. By 1828, the groundwork for the

B&O Railroad was underway (Holland 1987).

Because Howard County is located between the Baltimore and Washington

metropolitan areas, it has experienced a higher degree of urbanization in the last

50 years than it did in the previous three centuries. In 1950, the population of Howard

County was 23,119; in 2000, it was 247,842.

Industry and Transportation

Howard County, which is one of 24 counties in Maryland, is part of the Washington

metropolitan area. There are numerous major private sector employers in the county.

Howard County has an excellent transportation infrastructure that includes I-70

and I-95, U.S. Route 29, Maryland Routes 32, 100, and 175, and many other

highways; however, because of their close proximity to Washington and Baltimore and

urban sprawl, a number of these highways have congestion problems during peak

flow periods. Commercial, industrial, and passenger rail transportation services are

readily available in the county, and four commuter rail locations serve heavy

employment areas in the county. Air transportation is provided by the BaltimoreWashington International Airport as well as Reagan National and Washington Dulles

International Airports.

Water Supply

Howard County depends on Baltimore City and the Washington Suburban Sanitary

Commission (WSSC) for all its public potable water supply. The present average daily

water requirement for the county is estimated at 24.3 million gallons.

About 21.7 million gallons per day is supplied through the public system, which

serves 83 percent of the county’s population. The remainder of the county’s

population is served by private wells or surface water supplies that produce an

estimated 2.6 million gallons per day. By the year 2015, the public system is expected

to serve about 86 percent of the county population.

The Howard County public water system is currently supplied through three

connections to the Baltimore County water system (which in turn is supplied from the
Soil Survey of Howard County, Maryland

3

Baltimore City system) and through one connection to the WSSC system. Howard

County both owns and operates the distribution system within its boundaries. It

participates in the planning and development and contributes to the capital cost of

improvements to the public potable water system outside of the county with these

other jurisdictions.

The primary source of water to Howard County from the City of Baltimore is the

Ashburton Filtration Plant. The raw water supply to the Ashburton Filtration Plant is

Liberty Reservoir, which is located on the North Branch of the Patapsco River. The

reservoir has a storage capacity of 43 billion gallons and a safe yield of 93 million

gallons per day.

WSSC supplies water to Howard County through the All Saints Road connection.

The connection allows Howard County a maximum daily withdrawal rate of 5.0 million

gallons. The raw water source for the WSSC supply is the Rocky Gorge Reservoir on

the Patuxent River. Water is treated at the Patuxent Water Filtration Plant and then

conveyed east to All Saints Road in Howard County.

Ultimately, Howard County will be provided with adequate capacity in the Leakin

Park Pump Station and Catonsville Transmission Main to supply a maximum day

demand of 50.5 million gallons (48.8 million gallons from the U.S. Route 40

connection and 1.7 million gallons from the Gun Road connection). This capacity,

along with the capacity available from the county’s other connections, will satisfy

Howard County’s needs as it builds out of the planned service area.

Ground water from the crystalline rock formations that underlie Howard County will

continue to be the major source of potable water in the western part of the county,

which is outside the county’s planned water service area. Howard County has no

plans to allow the development of community wells. Recharge of the aquifer occurs

primarily through the infiltration of rain through surface soils and into the bedrock.

Total average daily recharge of the aquifer was estimated to be 0.36 million gallons

per square mile or 54.2 million gallons for the entire nonplanned water service area.

The overall quality of the ground water flowing through the crystalline rock in

Howard County was good to excellent, although the soft, acidic nature of the water

can cause corrosion of metal plumbing. It has essentially remained constant over the

past 30 years, and there are no long-term degradation problems with the quality of

ground water within the western part of the county (Howard County master plan for

water and sewerage 1999).

Geology and Associated Soils

Scott Southworth, U.S. Geological Survey, helped to prepare this section.

Howard County lies mostly within the Piedmont Physiographic Province of

Maryland except for the extreme eastern and southeastern parts of the county,

which are underlain by unconsolidated sediments of the Atlantic Coastal Plain

Physiographic Province. The Piedmont Province is characterized in the county by

several distinct sections. These sections are bounded by faults that separate different

geologic formations.

Piedmont Province

The extreme western part of the county is underlain by metasiltstone and phyllite

(both impregnated with vein quartz) of the Marburg Formation, sometimes referred to

as the Gilis Group and the Prettyboy Schist Formation of the Westminster Terrane.

Soils generally associated with this region are those in the Blocktown, Brinklow,

Glenelg, Glenville, Occoquan, and Baile series. The Blocktown, Brinklow, and

Occoquan soils are shallower than the other named soils and generally have more

rock fragments associated with them.
Soil Survey of Howard County, Maryland

The west-central part of the county is underlain by the Liberty Complex, which

consists of a heterogeneous assemblage of metagraywacke and schist (the Morgan

Run Formation) and quartzofeldspathic gneiss (the Sykesville Formation). Soils

associated with these formations are those in the Glenelg, Glenville, Manor, Baile,

Gaila, and, to a lesser extent in the Sykesville Formation, Gladstone series (fig. 2).

Minor inclusions of Brinklow and Blocktown soils are common on eroded interfluves,

shoulder slopes, and steep backslopes. Both of these soils contain map-scale bodies

of mafic and ultramafic rocks. The Legore and Montalto soils are associated with the

mafic and ultramafic rocks, which are in a narrow band that has a north-south

orientation. This band is about one-quarter to one-half mile wide and runs from the

Patapsco River in the north through Slacks Corner, Ivory, and Glenelg down to

Triadelphia Reservoir in the south. A few isolated pods are located near Carrs Mill,

Woodbine, and Hoods Mill. The western boundary of the fault zone is the Pleasant

Grove fault, and the sheared rocks immediately east of the fault zone are in the

Pleasant Grove Formation. Rock outcrops are commonly associated with this

formation because of the amount of quartz in the rock. The best expression of this is

south of I-70 along Maryland Route 94. The eastern boundary is also bounded by a

fault, but the shear zone is not as wide as it is along the Pleasant Grove fault.

The eastern half of the Piedmont Province can be subdivided into two distinct

sections. The western part consists of gneiss (Baltimore Gneiss) overlain by quartzite

(Setters Quartzite), marble (Cockeysville Marble), and schist (Loch Raven and Oella

Formations). The major soils associated with the Cockeysville Marble are those in the

Benevola and Wiltshire series. The major soils associated with the Loch Raven and

Oella Formations generally have a higher content of mica than their counterparts in

other areas of the county. The easternmost part of the Piedmont Province, around

Elioak, Longfellow, and Atholton and beyond, consists of a complex assemblage of

igneous rocks, which includes gneiss, amphibolite, serpentine, and granite. The soils

associated with this assemblage of rocks are those in the Bannertown, Gladstone,

Jackland, Legore, Mount Lucas, and, to a lesser extent, Glenelg series. Because of

the complexity of this region, it is common to find a thin remnant of coastal sediments

overlying the residuum. This region has been highly altered by residential and urban

development.

health, soils, and waste management. The Glenelg, Gladstone, and Manor soils, which are in

areas of the farm, represent a major portion of the Piedmont Province in Maryland.
Soil Survey of Howard County, Maryland

Atlantic Coastal Plain Province

The rocks of the eastern part of the Piedmont Province are uncomformably

overlain by unconsolidated gravel, sand, and clay of the Patuxent Formation and

terrace deposits that collectively make up the Atlantic Coastal Plain Province. Major

soils associated with the Atlantic Coastal Plain Province include those in the

Beltsville, Chillum, Croom, Evesboro, Fallsington, Russett, Sassafras, and

Woodstown series. The region is highly complex, and remnant coastal sediments

commonly overlie the residuum in areas of the Glenelg, Gladstone, Legore, and

Manor soils. This region has been highly altered by urban, industrial, and residential

development.

Agriculture

Caragh B. Fitzgerald, Maryland Cooperative Extension, Howard County, helped to prepare this section.

Howard County has some of the richest soils suitable for agriculture operations in

the State. It also receives a good amount of rainfall and is close to markets. In 1968,

about 72 percent of the 162,100 acres in the county was identified as prime farmland

or land suitable for intensive agricultural production (Matthews and Hershberger

1968). However, the recent growth of residential areas in Howard County due to

urban sprawl has significantly reduced the acreage of agricultural land that was once

considered prime farmland. The entire county is under immense pressure from

residential and commercial developers. The 1997 county profile shows an 11 percent

decrease in farmland, from 44,623 acres in 1992 to 39,846 in 1997, but an increase

in the average size of farms by 7 percent, from 117 acres to 125 acres, within the

same period of study. Despite the loss of farmland in the county, agriculture is still the

biggest revenue generator, accounting for about $87.6 million of the county’s

assessable tax base (Howard County comprehensive plan 2000; USDA NASS 1997).

Many of the soils in the county are well suited to intensive agricultural production.

Examples of these soils are those in the Benevola, Gladstone, Glenelg, Legore, and

Manor series. The main agricultural enterprises in areas of these soils are dairying

and growing fruit, grain, vegetable, and nursery products. Shallower soils, such as

those in the Blocktown series, are better suited to perennial hay crops and to grasses

and legumes for pasture.

Most of the orchards are in the western part of the county. They are in areas of the

Brinklow, Gaila, Glenelg, Manor, and Occoquan soils.

Soil erosion by wind or water and contamination of surface water or ground water

by excess plant nutrients, primarily nitrogen and phosphorus, are common concerns

when maximizing agricultural productivity of soils. Establishing and maintaining

buffers, such as hedgerows and woodlots, and not plowing in the fall help to control

erosion. Applying a system of conservation tillage, such as minimum tillage or notillage, and planting a cover crop help to control erosion.

Stripcropping in conjunction with diversions and waterways mitigates the velocity of

water moving over the soil surface by breaking up the total slope lengths. Diversions

break up the slope lengths and redirect the surface flow of the fields to a controlled

waterway or outlet. Using proper crop rotations and alternating the vegetative cover,

for example, corn with small grain, hay, or soybeans, will reduce the runoff rate.

Erosion-control practices benefit the environment by reducing the rate of runoff,

minimizing sedimentation, increasing the organic matter content of the soil,

increasing the amount of water that infiltrates the soil, conserving soil moisture, and

reducing the amount of fuel used to operate equipment.

Organic matter is an essential element in soil quality, soil tilth, and water infiltration.

The average organic matter content in the soil surface ranges from 1 to 3 percent in

Howard County; however, in some severely eroded areas on steep slopes and around
Soil Survey of Howard County, Maryland

6

rock outcrop, the organic matter content is less than 1 percent. In recent years, with

the removal of small grain residue as straw or silage and the utilization of corn as

silage and corn stubble grazing as a feed source, the organic matter content of soils

in the county has declined.

Organic matter content can be increased by growing green manure crops, such as

winter cover crops; applying animal manure; and adopting no-till crop production

practices. An increase in the organic matter content improves the water- and nutrientholding capacity of the soil and thus helps to control erosion, minimize compaction,

and reduce the incidence of plant diseases.

Contour stripcropping is not recommended, nor is it practical, in areas of soils that

have a rocky surface or in areas where the soils are intermingled with rock outcrop. In

Howard County, detailed soil map units MgF, Manor-Bannertown sandy loams, 25 to

65 percent slopes, rocky, and MkF, Manor-Brinklow complex, 25 to 65 percent slopes,

very rocky, have a rocky surface and steep and very steep slopes. The rockiness in

combination with the steep and very steep slopes inhibit the establishment of contour

strips.

Crops

Because livestock production in the county is extensive, field and forage crops are

the predominant crops produced. Corn and soybeans are the primary crops grown for

grain. The percentage of corn harvested for grain or chopped for silage varies

somewhat seasonally depending on the producer’s need for feed and the weather. In

dry years, when the corn yield is depressed and feed supplies are low, more acres of

corn are chopped. Small grain crops, such as wheat, barley, and hay, generally are

harvested for grain and silage and occasionally are used as pasture. In 1997, a total

of 39,846 acres was used as cropland. Crops were harvested on 23,535 acres, which

is a 10 percent decrease from the number of acres harvested in 1992 (USDA NASS

1997).

In 1997 and 2001, the yields per acre for field and forage crops were, respectively,

69.2 and 119.8 bushels of corn for grain; 10.6 and 17.1 tons of corn for silage; 27 and

40 bushels of soybeans; 62.4 and 60.0 bushels of wheat; 86.2 and 77.8 bushels of

barley; and 1.93 and 2.20 tons of hay (USDA NASS 2002).

The horticulture, nursery and greenhouse, and turf grass industries in Howard

County make up the second largest commodity group in Maryland, with 16 percent of

the State’s total cash agricultural sales. The production of specialty crops has

significantly increased over the past decade due in part to the urbanization of the

county and region. In 1997, there were 98 operations with 46 farms in production.

The farms encompassed 1,544 acres (USDA NASS 1997). Smaller farms suited to

certified organic farming are emerging forms of agriculture in the county. About

10 percent of all certified organic farms in Maryland are in Howard County. These

farms have an average size of less than 20 acres and are operated by full-time

farmers.

Livestock

Livestock and livestock products are important farm commodities of the county. In

1992, a total of 8,864 head of livestock were reported, compared to 6,458 head of

livestock in 1997, a decrease of 25 percent. The livestock in 1992 and 1997 included,

respectively, 4,624 and 3,370 cattle and calves; 1,429 and 1,357 dairy cows;

1,730 and 1,254 hogs and pigs; and 1,081 and 477 sheep and lambs (USDA NASS

1997). The number of horses in the county is no longer reported in the agricultural

census; however, the equine industry in Howard County plays an integral role in the

county’s heritage, identity, and economy. The industry generates about $140 million in

business annually.
Soil Survey of Howard County, Maryland

Type and Size of Farms

Between 1992 and 1997, the number of farms in Howard County decreased from

382 to 318, or approximately 17 percent. In 1997, there were 54 farms less than

10 acres in size, 131 farms ranging from 10 to 49 acres in size, 85 farms ranging from

50 to 179 acres in size, 28 farms ranging from 180 to 499 acres in size, 11 farms

ranging from 500 to 999 acres in size, and 9 farms 1,000 acres or more in size. The

number of farms less than 1,000 acres in size decreased between 1992 and 1997,

but the number of farms that were more than 1,000 acres in size increased during

that period (USDA NASS 1997).

Of the 318 farms in the county in 1997, full-time farming operations accounted for

127 farms (a decrease of 28 percent since 1992) and part-time farming operations for

the remaining 191. The bulk of farm cash receipts were derived from crop sales,

which accounted for 62 percent, and livestock sales, which accounted for 38 percent

of the market value of agricultural products (fig. 3). The county has had an overall

decrease in farming activities over the past several years.

Mineral Resources

Howard County’s principal mineral resources are sand and gravel, materials of

great importance to the construction industry. The sand and gravel, which is limited to

areas of the Atlantic Coastal Plain Province, stretches from the Howard and Anne

Arundel County border westward to a line running northeast to southwest, about

midpoint between Maryland Route 29 and I-95. There is potential for crushed stone

production west of I-95, in areas of the Piedmont Province, based on mineral

resources prevalent in the province.

Currently, there is only one mining operation in Howard County. This facility

quarries natural building stone.

operations.

A number of factors constrain or limit the mining industry in Howard County,

including urbanization, legal restrictions, environmental concerns associated with

surface mining, easements, incompatible zoning, and prohibitive property values.

These restrictions have resulted in the decrease of mining activities in the county.

Restrictions on mining operations are incorporated in State permit procedures and

Howard County’s zoning regulations, which allow sand and gravel mining only in rural

and industrial areas. Mining operations are not permitted in residential districts other

than rural districts.

Climate

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

recorded at Clarksville in the period 1961-90. Table 2 shows probable dates of the

first freeze in fall and the last freeze in spring. Table 3 provides data on length of the

growing season.

In winter, the average temperature is 33.4 degrees F and the average daily

minimum temperature is 23.1 degrees. The lowest temperature on record, which

occurred on January 22, 1984, is -18 degrees. In summer, the average

temperature is 73.2 degrees and the average daily maximum temperature is

85.3 degrees. The highest recorded temperature, which occurred on July 16, 1988,

is 103 degrees.

Growing degree days are shown in table 1. They are equivalent to “heat units.”

During the month, growing degree days accumulate by the amount that the average

temperature each day exceeds a base temperature (40 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 total annual precipitation is about 45.94 inches. Of this, 25.33 inches, or

55 percent, usually falls in May through October. The growing season for most crops

falls within this period. In 2 years out of 10, the rainfall in May through October is

less than 13.27 inches. The heaviest 1-day rainfall during the period of record was

9.13 inches on June 22, 1972. Thunderstorms occur on about 28 days each year, and

most occur during the period ranging from May through August.

The average seasonal snowfall is about 22.3 inches. The greatest snow depth at

any one time during the period of record was 23 inches. On the average, 22 days of

the year have at least 1 inch of snow on the ground. The number of such days varies

greatly from year to year. The heaviest 1-day snowfall on record was 18.2 inches

recorded on February 23, 1987.

The average relative humidity in midafternoon is about 55 percent. Humidity is

higher at night, and the average at dawn is about 70 percent in winter and 80 to

85 percent in summer. The sun shines about 63 percent of the time possible in

summer and about 52 percent in winter. The prevailing wind is from the west.

Average windspeed is highest, about 11 miles per hour, in March and April.

How This Survey Was Made

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

areas in the survey area. The information includes a description of the soils and

miscellaneous areas and their location and a discussion of their 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
Soil Survey of Howard County, Maryland

9

unconsolidated material is devoid of roots and other living organisms and has not

been changed by other biological activity.

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

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

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

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

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

landform, a soil scientist develops a concept or model of how they were formed. Thus,

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

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

landscape.

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

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

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

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

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

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

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

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

rock fragments, distribution of plant roots, 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 fieldobserved characteristics and the soil properties to determine the expected behavior

of the soils under different uses. Interpretations for all of the soils are field tested

through observation of the soils in different uses and under different levels of

management. Some interpretations are modified to fit local conditions, and some new

interpretations are developed to meet local needs. Data are assembled from other

sources, such as research information, production records, and field experience of

specialists. For example, data on crop yields under defined levels of management are

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

soil.

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

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

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

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

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

high 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.

Survey Procedures

This soil survey updates the survey of Howard County published in 1968

(Matthews and Hershberger 1968). It provides additional data and soil interpretations

and larger maps, which show the soils in greater detail. The soils in this survey are

described to a greater depth than in the previous survey. Many of the soil series and

map unit names have been changed because of new information and changes in the

national system for soil classification. Although some soil boundaries have been

readjusted, many are essentially the same as those in the original survey.

The general procedures followed in making the survey are described in the

“National Soil Survey Handbook” of the Natural Resources Conservation Service

(USDA NRCS n.d.). The earlier published soil survey, the county geology map, and

other references were used to prepare the manuscript and to plan the soil transects.

Before fieldwork began, color infrared aerial photographs taken in 1991 at a scale

of 1 inch:1,000 feet were studied. These aerial photographs provided information that

was significant in determining the location of certain soil boundaries in woodland

areas. All the profile descriptions from the 1968 report representing the modal or

central concept of the soil series were investigated and described using new

terminology and nomenclature. They were used as a starting point for evaluating the

old map units. A reconnaissance was made by vehicle before the landscape was

traversed on foot. The field transects were used to identify any changes needed in the

central concept of the series and to determine map unit composition. Some areas

required remapping, particularly urban areas, such as Columbia and Ellicott City, and

areas on alluvial flood plains. Soil boundaries were determined on the basis of soil

examinations, observations, and photo interpretation.

Some of the soil series in the 1968 survey could not be used. New information on

soil temperature, particle-size distribution, and water tables indicated the need for the

establishment of new series. Many of the new series and some of the older series

were sampled for chemical and physical analyses and for analyses of engineering

properties. Particle-size distribution, mineralogy analyses, and special studies related

to soils throughout the county were made by the Pedology Research Laboratory,

Department of Agronomy, University of Maryland. A description of the laboratory

procedures can be obtained from the laboratory or from the State office of the Natural

Resources Conservation Service.

Soil Survey of Howard County, Maryland

The origin and development of the soils in Howard County are explained in this

section. The five major factors of soil formation are identified, and their influence on

the soils in the county is described. Also, the morphology of the soils is related to

horizon nomenclature and the processes of horizon development.

Factors of Soil Formation

Soil is a three-dimensional body consisting of organic matter, mineral matter, air,

and water. Soils formed through the chemical and physical weathering of geologic

materials. The extent of the weathering and the characteristics of any soil depend on

the nature of the parent rock; the climate; the relief, or lay of the land; the plant and

animal life in and on the soil; and the length of time these factors have affected

development.

In a small area, such as Howard County, the vegetation, climate, and time factors

vary only slightly. The nature of the parent material and the relief are responsible for

most of the differences in soil properties. The nature of the parent rock determines

the texture and mineral content of the soils. Relief affects drainage, aeration, runoff,

erosion, and exposure to sun and wind. Plant and animal life influences soil

characteristics by physical and chemical removals and additions. Climate influences

the nature and extent of the weathering processes. Time is required for the processes

responsible for soil formation. Long periods generally are needed for soil

development.

Parent Material

Parent material is the unconsolidated mass from which the soils are formed. It

determines the mineralogical and chemical composition of the soil and, to a large

extent, the rate at which soil-forming processes take place. In the early stages of soil

formation, the mineralogical, physical, and chemical properties of the soil closely

resemble those of the parent material. The composition of Glenelg soils, for example,

is similar to the acid phyllite from which the soils formed. As a soil ages, the

processes of soil formation alter rocks and minerals, and the resulting soils usually

have different characteristics.

Howard County is unique in that it contains two distinctively contrasting

physiographic regions. The Piedmont Province is the major physiographic region in

the county. Soils in this region formed in place directly over the original bedrock. The

Atlantic Coastal Plain Province is of minor extent in the county. Soils in this region

formed in unconsolidated sediments deposited by water and wind. Because these

sediments were deposited in fluvial and marine environments, they are referred to as

fluviomarine. A 2- to 3-mile area paralleling I-95 is known as the fall line where the

Atlantic Coastal Plain Province meets the Piedmont Province. The soils in this area

vary greatly and are not easily identified in the field. They have properties of coastal

sediments and Piedmont materials.

Many soils in Howard County formed in place in residuum directly over the original

bedrock. Brinklow, Blocktown, Glenelg, Glenville, Gaila, Manor, and Occoquan soils

Formation of the Soils
Soil Survey of Howard County, Maryland

formed in material derived from tan, light silvery gray, olive green, and dull purple

phyllite and schist with varying amounts of mica. Benevola and Wiltshire soils formed

in material derived from marble bedrock. Legore, Montalto, and Relay soils formed in

material derived from mafic and ultra mafic rocks. Gladstone and Bannertown soils

formed in material derived from gneissic rocks. Alloway, Beltsville, Chillum, Croom,

Evesboro, Fallsington, Russett, and Sassafras soils formed in coastal sediments.

Climate

The climate of Howard County is the humid-temperate, continental type. Some

characteristics of the soils in the county indicate that this climate prevailed when the

soils were forming and that it affected soil formation. Many of the soils are acid and

strongly leached. The effect of climate on the formation of soils has been nearly

uniform throughout the county. The formation of some soils, however, may have been

affected by a microclimate caused by differences in relief.

Plants and Animals

Vegetation, animals, bacteria, and fungi affect soil formation. The vegetation is

generally responsible for the amount of nutrients. Earthworms, cicadas, and other

burrowing animals help to keep the soil open and release nutrients for plant food. The

native forests in Howard County have had more influence on soil formation than have

any other living organism. People, however, have greatly influenced the surface layer

of soils when they cleared the forests and plowed the land. They also have added

fertilizers, mixed some of the soil horizons, and moved soil materials from place to

place.

Relief

The relief in Howard County is dominated by rolling valleys and steep ridges. It has

been influenced by the strongly folded and faulted metamorphic and igneous rocks

and their degree of resistance or susceptibility to physical and chemical weathering

and erosion. The soils in highly dissected areas along major rivers, such as the

Patuxent, Patapsco, and Middle Patuxent Rivers, are a direct result of erosion. Gaila,

Glenelg, Brinklow, Blocktown, and Occoquan soils are on the lower hills and ridges.

Legore, Montalto, and Relay soils are on the higher ridges in areas of igneous rock.

The coastal plain and fall line regions have been highly dissected by erosion, which

is a result of the elevation change in the county from about 780 feet near Poplar

Springs to about 100 feet near Elkridge. In these regions, erosion has removed the

coastal sediments, exposing the residuum. Legore and Montalto soils formed in these

areas.

Relief affects soil formation through its effect on surface drainage, the permeability

of the soil, the plant and animal life on and in the soil, and some of the soil-forming

processes. Baile and other poorly drained soils in depressions are generally wet.

Glenelg and Gaila soils are in the higher convex areas and are better drained than

the Baile soils. Soils on the steeper slopes are well drained and generally have

weakly expressed horizons as a result of erosion. They include the Blocktown and

Brinklow soils.

Natural differences in elevation and in the shape of the land surface account for

many of the differences among soils that formed in the same kind of parent material.

Because of differences in topography, free water leaves well drained soils and

accumulates in poorly drained soils.

Time

The length of time the soil-forming factors have acted on the mineral material is

indicated by the degree of development in the soil profile. Soils formed in alluvium,

such as those in the Hatboro and Codorus series, are considered young or recent
Soil Survey of Howard County, Maryland

because their parent material has been in place for a shorter period of time than that

of other soils in the county. These soils have less distinct horizons than older soils on

uplands. Glenelg, Gladstone, and Legore soils have well developed profiles. The

parent material of these soils has been in place for a period long enough that distinct

horizons have had time to develop.

Morphology of the Soils

The morphological features of soil are the result of soil-forming factors. They are

expressed in the development of different layers, or horizons, which make up a soil

profile. The soil profile extends from the surface down to material that is little altered

by the soil-forming processes.

Most soils have three major horizons—the A, B, and C horizons. Some soils,

particularly those in forests, also have an O horizon at the surface. Numbers or

lowercase letters indicate subdivisions of the major horizons. For example, the

Bt horizon has accumulated clay from the overlying horizons and is the most

developed part of a B horizon. Glenelg soils have a Bt horizon.

The O horizon is an organic layer. It consists of organic material, such as twigs,

leaves, dead roots, or humified organic matter, mixed with a small amount of mineral

material. Soils in forested areas may have a thin O horizon. Examples are the Legore,

Manor, and Montalto soils.

The A horizon is a mineral surface layer. It is darkened by humified organic matter.

In cultivated areas, the material in this horizon is mixed with material from the

underlying horizons and the result is a plow layer, or an Ap horizon. The amount of

humus or organic matter in the horizon varies in different soils and ranges from very

low to very high. The organic matter content in the Ap horizon of Baile and Glenville

soils can range up to 4 percent in places.

The E horizon, which commonly occurs in well developed, undisturbed soils,

is a mineral subsurface layer. It is characterized by intense leaching, or eluviation,

of clay and iron. An E horizon occurs if considerable leaching has taken place and

organic matter has not darkened the material. This horizon is normally lighter in

color than any other horizon in the profile. In cultivated areas, the material of this

horizon is commonly mixed with the overlying A horizon, and an E horizon may not

occur.

The B horizon is a mineral subsoil layer and normally underlies an Ap or E horizon.

It is characterized by the accumulation, or illuviation, of clay, iron, aluminum, or other

compounds leached from the surface layer. In some soils, such as Glenelg and

Benevola soils, the B horizon formed through alteration of the original material and

through accumulation or illuviation. The alteration can result from weathering of the

parent material; the release of iron, resulting in rusty colors; and the development of a

soil structure in place of the structure of the original unconsolidated sediments. The

B horizon commonly has blocky or prismatic structure. It generally is firmer and lighter

in color than the A horizon and is darker than the C and E horizons. In places affected

by previous erosion, the B horizon has been truncated and is relatively thin, only

10 to 20 inches thick. Gaila and Occoquan soils are representative of this

characteristic. Almost all of the soils in Howard County have a B horizon.

The C horizon is a mineral layer in the substratum, below an A or B horizon. It

consists of material that is little altered by the soil-forming processes, but it may be

modified by weathering. When the soil material of a C horizon is different than the

parent material from which the overlying A and B horizons developed, the C horizon

is labeled as a 2C horizon. Most of the soils in Howard County have a C or

2C horizon. In some young soils, such as those that formed in recent alluvium, the

C horizon extends to or nearly to the surface. These soils do not have an E or

B horizon. Hatboro soils are an example.

Processes of Soil Formation

Soil forms through complex processes that can be grouped into four general

categories—additions; removals, or losses; transfers (from one horizon to another);

and transformations. These processes affect soil formation in differing degrees.

The accumulation and incorporation of organic matter in the surface layer is an

example of an addition. This addition is responsible for the formation of the A horizon

and is the main reason for the dark color of the surface horizon in the mineral soils of

Howard County. Heat from the sun and water from precipitation are also considered

additions. These additions assist with chemical and physical reactions and affect

other processes in the soil.

Carbonates, soluble salts, and the soluble products of mineral weathering that are

leached from the soil profile are examples of removals. In the soils of Howard County,

some of the compounds were removed before the parent materials were deposited.

Another example of a removal is erosion. On sloping soils most of the surface layer

may be lost and redeposited at the bottom of the slope or in a waterway. The

deposited materials are considered an addition.

The translocation of clay from the A and E horizons to the B horizon, which occurs

in many soils in the county, is an example of a transfer. In this process, clay is

dispersed in the upper horizons and subsequently moved downward by water into the

lower horizons, where it may be deposited by filtering, flocculation, or both. Thus, the

A or E horizon becomes the zone of eluviation, or loss, and the B horizon becomes a

zone of illuviation, or gain. In Benevola, Glenelg, Gladstone, Legore, and Sassafras

soils, the B horizon has more clay than the parent material (C horizon) and the

surface and subsurface layers (A and E horizons). In the B horizon of most soils, thin

clay films are in pores and on faces of peds. The clay has been transferred from the

A and E horizons.

Another important example of a transfer is the leaching or diffusion of iron in the

soil. This process takes place under saturated soil conditions where there is no

molecular oxygen. The naturally well drained soils in the county have a yellowish

brown or reddish brown subsoil. The color results from finely divided iron oxide

minerals (ferric iron) that coat the sand, silt, and clay particles. Under saturated

conditions, as in the poorly drained soils in the county, the iron oxide minerals are

chemically reduced to a more soluble form (ferrous iron). This form of iron is

transported with water and can be transported completely out of the horizon. The

remaining uncoated soil particles have a dominantly gray color. Normally, part of the

iron is reoxidized and segregated into the form of stains, concretions, or bright yellow

and red soft masses within the horizon. In the poorly drained Hatboro and Baile soils,

this type of transfer has occurred throughout the profile. Other examples of transfers

include the physical mixing of soil by animals, plants (as when trees tip over), and

humans. Nutrient recycling (bringing mineral elements to the soil surface) by plants is

also considered a transfer.

The weathering of primary materials to clay minerals in the soil is an example of a

transformation. It occurs by physical and chemical means, such as by the

transformation of micas and feldspars to clays. This process can increase the content

of clay during soil formation. Another kind of transformation occurs when clay is

derived from primary materials. Some iron generally is freed as a hydrated oxide.

Depending on the degree of hydration, the oxide is generally red. Even a small

amount of the oxide causes the subsoil to be reddish. Iron oxide colors the subsoil

even in soils where not enough clay minerals have accumulated to form a textural B

horizon, as in the Manor soils.

Soil Survey of Howard County, Maryland

The general soil map in this publication shows the soil associations in this

survey area. Each association has a distinctive pattern of soils, relief, and

drainage. Each map unit on the general soil map is a unique natural landscape.

Typically, an association 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 components of one unit 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 can be identified on the map. Likewise,

areas where the soils 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.

Soil Survey of Howard County, Maryland

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

six categories (Soil Survey Staff 1998, 1999). Beginning with the broadest, these

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

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

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

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

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

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

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

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 Udalf (Ud, meaning humid,

plus alf, from Alfisol).

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 Hapludalfs (Hapl, meaning minimal horizonation,

plus udalf, the suborder of the Alfisols that has a udic 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. The adjective Typic identifies the subgroup that typifies the

great group. An example is Typic Hapludalfs.

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

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

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

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

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

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

terms that indicate soil properties. An example is fine-loamy, mixed, active, mesic

Typic Hapludalfs.

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.

Classification of the Soils

23

Soil Survey of Howard County, Maryland

In this section, each soil series recognized in the survey area is described. Each

description is followed by the detailed soil map unit or units associated with the

series.

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 1998). 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.

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. More information about each map unit is given under the heading “Use

and Management of the Soils.”

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 included 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

Soil Series

and Detailed Soil Map Units

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, Glenelg

loam, 0 to 3 percent slopes, is a phase of the Glenelg series.

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

These map units are complexes or undifferentiated groups.

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. Brinklow-Blocktown channery loams, 25 to 65 percent slopes, is an

example.

An undifferentiated group is made up of two or more soils or miscellaneous areas

that could be mapped individually but are mapped as one unit because similar

interpretations can be made for use and management. The pattern and proportion of

the soils or miscellaneous areas in a mapped area are not uniform. An area can be

made up of only one of the major soils or miscellaneous areas, or it can be made up

of all of them. Codorus and Hatboro silt loams, 0 to 3 percent slopes, is an

undifferentiated group in this survey area.

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

and support little or no vegetation. Urban land is an example.

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

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

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

miscellaneous areas.

Alloway Series

The Alloway series consists of very deep, moderately well drained soils on nearly

level to sloping interstream divides of dissected uplands in the northern part of the

Atlantic Coastal Plain Province. These soils formed in silty and clayey eolian deposits.

Permeability is slow. Slope ranges from 0 to 15 percent.

Alloway soils are commonly in areas adjacent to Hambrook, Sassafras, Russett,

and Woodstown soils. Hambrook and Sassafras soils are well drained, have a fineloamy particle-size control section, and are on the higher lying ridges and hillslopes.

Russett and Woodstown soils are moderately well drained, have a fine-loamy particlesize control section, and are on landforms similar to those of the Alloway soils.

Chillum Series

The Chillum series consists of very deep, well drained soils on interstream divides,

knolls, and pediments and in ravines of dissected uplands in the northern part of the

Atlantic Coastal Plain Province. These soils formed in silty eolian deposits over

gravelly fluviomarine sediments. Permeability is moderate. Slope ranges from 0 to

15 percent.

Glenelg Series

The Glenelg series consists of very deep, well drained soils on nearly level to

strongly sloping uplands in the northern part of the Piedmont Province. These soils

formed in residuum derived from phyllite and micaceous schist. Permeability is

moderate. Slope ranges from 0 to 15 percent.

Glenelg soils are similar to Gaila soils and are adjacent to Baile, Gladstone,

Glenville, Manor, and Occoquan soils. The poorly drained Baile and moderately well

drained Glenville soils are in concave upland drainage swales and on concave upland

flats. They have a seasonal high water table within a depth of 40 inches. Gaila and

Occoquan soils have a solum that is thinner that that of the Glenelg soils. Occoquan

soils have bedrock within a depth of 60 inches. Manor soils do not have an argillic

horizon and average less than 18 percent clay throughout. They contain more mica

throughout. Gladstone soils formed in residuum derived from gneiss.

Jackland Series

The Jackland series consists of very deep, somewhat poorly drained soils on

upland flats and footslopes and in depressions on the Piedmont Province. These soils

formed in material weathered from mixed mafic rocks. Permeability is very slow. Slope

ranges from 0 to 8 percent.

Jackland soils are similar to Mount Lucas soils and are adjacent to Legore and

Montalto soils. Legore and Montalto soils have a seasonal high water table at a depth

of more than 40 inches. Legore soils are coarser textured than the Jackland soils, and

Montalto soils have a red subsoil. The moderately well drained Mount Lucas soils

average less than 35 percent clay throughout.

Montalto Series

The Montalto series consists of very deep, well drained soils on summits,

backslopes, and ridges. These soils formed in residuum derived from basic igneous

rocks. Permeability is moderate or moderately slow. Slope ranges from 3 to

25 percent.

Montalto soils are similar to Legore soils and are adjacent to Bannertown,

Gladstone, Jackland, Manor, Mount Lucas, Relay, and Watchung soils. Legore and

Relay soils have less than 35 percent clay in the particle-size control section and are

in similar landscape positions. The moderately well drained Mount Lucas, somewhat

poorly drained Jackland, and poorly drained Watchung soils formed in residuum

derived from similar rocks. They are in upland drainage swales and on concave

footslopes and slightly concave upland flats. The moderately deep Bannertown and

very deep Gladstone soils formed in residuum derived from gneiss and granitic

gneiss. They are in areas adjacent to the Montalto soils. The very deep Manor soils

formed in residuum derived from micaceous schist. They contain much more mica

than the Montalto soils and average less than 18 percent clay throughout. Relay soils

have more than 60 percent base saturation.

Sassafras Series

The Sassafras series consists of very deep, well drained soils in ravines and on

interstream divides, scarps, and terraces of deeply dissected uplands in the northern

part of the Atlantic Coastal Plain Province. These soils formed in loamy fluviomarine

sediments. Slope ranges from 0 to 60 percent.

Sassafras soils are adjacent to Beltsville, Chillum, Croom, Downer, Fallsington,

Hammonton, Russett, and Woodstown soils. The moderately well drained Beltsville

soils have a fragipan and are on landforms similar to those of the Sassafras soils.

Chillum soils contain less than 15 percent fine sand or coarser and have more rock

fragments in the substratum. Croom soils average more than 35 percent rock

fragments throughout. Downer and Hammonton soils average less than 18 percent

clay throughout. Fallsington soils are poorly drained. Russett and Woodstown soils

are moderately well drained.

UdB—Udorthents, loamy, 0 to 5 percent slopes

This map unit is on coastal plains. These nearly level to gently sloping soils

consist mostly of loamy fill material that has been placed on soils having various

drainage classes on terraces, uplands, and flood plains in the northern part of the

Atlantic Coastal Plain Province. These soils are used as sites for roads, buildings,

recreational facilities, and other development. Much of the acreage of this map unit

has undergone significant cutting, filling, grading, and compacting during the

construction of highways and their associated access ramps, drainage systems, and

medians. The soil material used during the construction generally is local in origin and

resembles the soils in adjacent map units. In areas where the original soil material

was unsuited to a specific use, material may have been hauled in to complete the

project.

Included in this map unit are areas used for storm water management and

sediment control that may have steeper slopes, be frequently ponded, or have riprap

on the surface. The depth to a seasonal high water table and the available water

capacity vary. Permeability is generally slow due to the compaction of the soils. The

hydrologic group assigned to these soils is D because the soils are generally

compacted either intentionally or unintentionally by vehicle traffic. Reaction is

generally very strongly acid or extremely acid. The chemical and physical properties

of these soils vary greatly.

Establishing a vegetative cover for stabilization can be difficult because of a low

level of soil fertility, acidic conditions, and compaction. A careful onsite investigation is

needed to determine the potentials and limitations of areas of this map unit for any

proposed land use.

These soils are not suited to agricultural uses or wildlife habitat, except in some of

the included areas. These soils are not hydric, but some very small included areas

may contain problematic hydric soils.

Woodstown Series

The Woodstown series consists of very deep, moderately well drained soils in

open depressions and on interstream divides, pediments, scarps, and terraces of

dissected uplands in the northern part of the Atlantic Coastal Plain Province. These

soils formed in loamy fluviomarine sediments. Permeability is moderate. Slope ranges

from 0 to 5 percent.

Woodstown soils are commonly in areas adjacent to Beltsville, Chillum, Croom,

Fallsington, Russett, and Sassafras soils. The moderately well drained Beltsville soils

have a fragipan. They are on landforms similar to those of the Woodstown soils. The

well drained Croom soils average more than 35 percent rock fragments throughout.

Fallsington soils are poorly drained, and Russett soils are moderately well drained.

Soil Survey of Howard County, Maryland

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

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

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

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

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

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

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

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

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

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

and other transportation systems, and parks and other recreational facilities; and for

agricultural waste management. 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

Use and Management of the Soils
Soil Survey of Howard County, Maryland

152

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 are listed, the system of land capability

classification used by the Natural Resources Conservation Service is explained, and

prime farmland and other important farmland are described.

Planners of management systems for individual fields or farms should consider the

detailed information given in the description of each soil under the heading “Soil

Series and Detailed Soil Map Units.” Specific information can be obtained from the

local office of the Natural Resources Conservation Service or the Cooperative

Extension Service.

Yields per Acre

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

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

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

other climatic factors. The land capability classification of map units in the survey area

also is shown in the table.

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

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

results of field trials and demonstrations also are considered.

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

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

control, and protection from flooding; the proper planting and seeding rates; suitable

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

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

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

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

smallest possible loss.

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.

Land Capability Classification

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

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

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

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

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

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

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

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

soils for forestland or for engineering purposes.
Soil Survey of Howard County, Maryland

153

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

class, subclass, and unit.

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

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

practical use. The classes are defined as follows:

Class 1 soils have slight limitations that restrict their use.

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

require moderate conservation practices.

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

special conservation practices, or both.

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

require very careful management, or both.

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

impractical to remove, that restrict their use mainly to pasture, rangeland, forestland,

or wildlife habitat.

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

cultivation and that restrict their use mainly to pasture, rangeland, forestland, or

wildlife habitat.

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

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

Class 8 soils and miscellaneous areas have limitations that preclude commercial

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

watershed, or esthetic purposes.

Capability subclasses are soil groups within one class. They are designated by

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

shows that the main hazard is the risk of erosion unless close-growing plant cover is

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

cultivation (in some soils the wetness can be partly corrected by artificial drainage); s

shows that the soil is limited mainly because it is shallow, droughty, or stony; and c,

used in only some parts of the United States, shows that the chief limitation is climate

that is very cold or very dry.

In class 1 there are no subclasses because the soils of this class have few

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

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

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

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

table.

Prime Farmland and Other Important Farmland

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

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

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

production of the Nation’s food supply.

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

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

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

prime farmland.

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

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

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

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

land or water areas. The soil quality, growing season, and moisture supply are those
Soil Survey of Howard County, Maryland

154

needed for the soil to economically produce sustained high yields of crops when

proper management, including water management, and acceptable farming methods

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

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

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

rocks. The water supply is dependable and of adequate quality. Prime farmland is

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

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

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

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

Natural Resources Conservation Service.

About 53,745 acres, or 33.2 percent of the survey area, would meet the

requirements for prime farmland if an adequate and dependable supply of irrigation

water were available.

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

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

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

productive and cannot be easily cultivated.

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

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

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

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

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

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

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

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

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

35,891 acres, or 22 percent of the total acreage in the county, meets the soil

requirements for additional farmland of statewide importance.

The map units in the survey area that are considered prime farmland or farmland

of statewide importance are listed in table 7. This list does not constitute a

recommendation for a particular land use. On some soils included in the list,

measures that overcome a hazard or limitation, such as flooding, wetness, and

droughtiness, are needed. Onsite evaluation is needed to determine whether or not

the hazard or limitation has been overcome by corrective measures. The extent of

each listed map unit is shown in table 5. The location is shown on the detailed soil

maps. The soil qualities that affect use and management are described under the

heading “Soil Series and Detailed Soil Map Units.”

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.

Tables 8a, 8b, and 8c show the degree and kind of soil limitations affecting the

treatment of agricultural waste, including municipal and food-processing wastewater

and effluent from lagoons or storage ponds. Municipal wastewater is the waste

stream from a municipality. It contains domestic waste and may contain industrial

waste. It may have received primary or secondary treatment. It is rarely untreated

sewage. Food-processing wastewater results from the preparation of fruits,

vegetables, milk, cheese, and meats for public consumption. In places it is high in

content of sodium and chloride. In the context of these tables, the effluent in lagoons

and storage ponds is from facilities used to treat or store food-processing wastewater
Soil Survey of Howard County, Maryland

155

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 tables 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) and for waste management systems that are designed only

for the purpose of wastewater disposal and treatment (overland flow of wastewater,

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

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

to which the soils are limited by all of the soil features that affect agricultural waste

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

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

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

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

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

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

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

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

and high maintenance can be expected.

Numerical ratings 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).

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

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

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

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

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

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

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

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

in the ratings.

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

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

which the waste is applied. The properties that affect absorption include 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, the soil erodibility 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
Soil Survey of Howard County, Maryland

156

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, the soil

erodibility 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.

Overland flow of wastewater is a process in which wastewater is applied to the

upper reaches of sloped land and allowed to flow across vegetated surfaces,

sometimes called terraces, to runoff-collection ditches. The length of the run generally

is 150 to 300 feet. The application rate ranges from 2.5 to 16.0 inches per week. It

commonly exceeds the rate needed for irrigation of cropland. The wastewater leaves

solids and nutrients on the vegetated surfaces as it flows downslope in a thin film.

Most of the water reaches the collection ditch, some is lost through

evapotranspiration, and a small amount may percolate to the ground water.

The ratings in the table are based on the soil properties that affect absorption,

plant growth, microbial activity, and the design and construction of the system.

Reaction and the cation-exchange capacity affect absorption. Reaction, salinity, and

the sodium adsorption ratio affect plant growth and microbial activity. Slope,

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

cemented pan, stones, and cobbles affect design and construction. Permanently

frozen soils are unsuitable for waste treatment.

Rapid infiltration of wastewater is a process in which wastewater applied in a level

basin at a rate of 4 to 120 inches per week percolates through the soil. The

wastewater may eventually reach the ground water. The application rate commonly

exceeds the rate needed for irrigation of cropland. Vegetation is not a necessary part

of the treatment; hence, the basins may or may not be vegetated. The thickness of the

soil material needed for proper treatment of the wastewater is more than 72 inches.
Soil Survey of Howard County, Maryland

157

As a result, geologic and hydrologic investigation is needed to ensure proper design

and performance and to determine the risk of ground-water pollution.

The ratings in the table are based on the soil properties that affect the risk of

pollution and the design, construction, and performance of the system. Depth to a

water table, ponding, flooding, and depth to bedrock or a cemented pan affect the risk

of pollution and the design and construction of the system. Slope, stones, and

cobbles also affect design and construction. Permeability and reaction affect

performance. Permanently frozen soils are unsuitable for waste treatment.

Slow rate treatment of wastewater is a process in which wastewater is applied to

land at a rate normally between 0.5 inch and 4.0 inches per week. The application

rate commonly exceeds the rate needed for irrigation of cropland. The applied

wastewater is treated as it moves through the soil. Much of the treated water may

percolate to the ground water, and some enters the atmosphere through

evapotranspiration. The applied water generally is not allowed to run off the surface.

Waterlogging is prevented either through control of the application rate or through the

use of tile drains, or both.

The ratings in the table are based on the soil properties that affect absorption,

plant growth, microbial activity, erodibility, and the application of waste. The properties

that affect absorption include the sodium adsorption ratio, depth to a water table,

ponding, available water capacity, permeability, depth to bedrock or a cemented pan,

reaction, the cation-exchange capacity, and slope. Reaction, the sodium adsorption

ratio, salinity, and bulk density affect plant growth and microbial activity. The wind

erodibility group, the soil erodibility factor K, and slope are considered in estimating

the likelihood of wind erosion or water erosion. Stones, cobbles, a water table,

ponding, and flooding can hinder the application of waste. Permanently frozen soils

are unsuitable for waste treatment.

Forest Productivity and Management

David Plummer, Maryland Forest Service, helped to prepare this section.

When Howard County was established in 1851, most of the land was forested. The

predominant tree species were deciduous hardwoods, but some evergreen species

were also included. As settlement progressed and the application of agricultural

practices increased, the acreage used as forestland in the county began to decrease.

It continued to decrease even further because of the improved means of

transportation, advances in agriculture, commercial logging, and diseases such as

chestnut blight and Dutch elm disease. Today, many of the native tree species have

been replaced by pioneer species, which are those that are strong enough or robust

enough to compete with grasses and other pioneer plants and can thrive in full

sunlight since there are no other trees to shade them.

As of 1995, about one-third of Howard County was estimated to be forested. Most

of this acreage is in publicly owned areas including, but not limited to, Patapsco Valley

State Park, Patuxent State Park, Hugg Thomas Wildlife Management Area, and the

Middle Patuxent Environmental Area. The remaining acreage of forestland is privately

owned. It is mainly in areas that are either too wet or are too steep and stony to be

used for agriculture.

Most of the forestland in the county is in areas of the Piedmont Plateau. Ridges

and upper backslopes are dominated by chestnut, scarlet, black, and white oaks;

hickory; and red maple. Common soils in these areas include those in the Glenelg,

Occoquan, Gladstone, Manor, and Gaila series. Also included are the finer textured

Montalto, Legore, and Benevola soils. Forests in areas ranging from the middle

backslopes down to the footslopes are dominated by red and white oaks; yellow

poplar; shagbark hickory; red and sugar maples; black cherry; and black walnut.

Common soils in these areas include those in the Relay, Legore, Brinklow, Blocktown,

and Bannertown series. These soils commonly have stones at the soil surface and

have slope of more than 25 percent. They occasionally are mapped with areas of rock

outcrop. Trees in drainage areas and on flood plains include sycamore; yellow poplar;

red and silver maples; black walnut; pin and swamp white oaks; locust; green ash; and

boxelder. Soils common to these areas include those in the Glenville, Baile, Hatboro,

Codorus, Wiltshire, Mt. Lucas, and Watchung series. The Mt. Lucas and Watchung

soils commonly have fragments ranging in size from cobbles to boulders at the soil

surface.

The forestland in areas of the Atlantic Coastal Plain Province is most affected by

urbanization. The remaining forests are primarily along waterways or on wet uplands

or are privately owned. Upland and lowland tree species are often closely associated

because the soils vary. Trees associated with the dry uplands include white and

chestnut oaks; laurel; yellow poplar; beech; sweet gum; and hickory. The understory

commonly includes trees such as dogwood, serviceberry, and pawpaw. The soils

included in these areas are those in the Evesboro, Downer, Chillum, Russett,

Sassafras, Croom, and Beltsville series. Pitch pine and Virginia pine are common as

plantations for reforestation. Trees on the lowlands and moist uplands include

southern red oak, sweetgum, sycamore, green ash, hackberry, and red maple. Soils

include those in the Alloway, Woodstown, Hammonton, and Fallsington series.

Loblolly pine is common in plantations for reforestation.

Many factors influence the health and composition of present and future forests.

Currently some of the more obvious threats include increasing population and

development, improper forest management, invasive plants, disease, insects, and

damage caused by deer browsing.

The gypsy moth and the decline of oak trees will likely continue to be a problem in

oak dominated forests, eventually creating different structural and compositional

changes within the forests.

The tables in this section can help forest owners or managers plan the use of soils

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

rate the soils according to the limitations that affect various aspects of forest

management.

Forest Productivity

In table 9, the potential productivity of merchantable or common trees on a soil is

expressed as a site index and as a volume number. The site index is the average

height, in feet, that dominant and codominant trees of a given species attain in a

specified number of years. The site index applies to fully stocked, even-aged,

unmanaged stands. Commonly grown trees are those that forest managers generally

favor in intermediate or improvement cuttings. They are selected on the basis of

growth rate, quality, value, and marketability. More detailed information regarding site

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

of the Natural Resources Conservation Service or on the Internet.

The volume of wood fiber, a number, is the yield likely to be produced by the

most important tree species. This number, expressed as cubic feet per acre per

year and calculated at the age of culmination of the mean annual increment (CMAI),

indicates the amount of fiber produced in a fully stocked, even-aged, unmanaged

stand.

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

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

Forest Management

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

forest management. The ratings are both verbal and numerical.
Soil Survey of Howard County, Maryland

159

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

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

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

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

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

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

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

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

unfavorable properties requires special design, extra maintenance, and costly

alteration. Unsuited indicates that the expected performance of the soil is

unacceptable for the specified practice or that extreme measures are needed to

overcome the undesirable soil properties.

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

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

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

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

feature is not a limitation (0.00).

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

for forest management practices. More detailed information about the criteria used in

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

offices of the Natural Resources Conservation Service or on the Internet (http://

soils.usda.gov/technical/nfmanual/).

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

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

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

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

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

that no significant limitations affect construction activities, moderate indicates that

one or more limitations can cause some difficulty in construction, and severe

indicates that one or more limitations can make construction very difficult or very

costly.

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

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

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

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

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

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

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

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

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

indicates that ruts form readily.

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

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

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

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

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

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

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

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

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

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

and generally impractical.

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

erodibility factor K, slope, and content of rock fragments. The ratings apply to
Soil Survey of Howard County, Maryland

160

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

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

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

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

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

costly erosion-control measures are needed.

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

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

classification, depth to a water table, ponding, flooding, and the hazard of soil

slippage. The ratings indicate the suitability for using the natural surface of the soil for

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

this use.

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

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

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

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

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

completed before seedlings are planted.

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

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

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

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

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

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

below the surface, depth to a water table, and ponding. The soils are described as

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

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

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

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

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

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

of about 3 feet is considered in the ratings.

Recreation

The land included in parks, recreational areas, and open spaces serves different

purposes and has different characteristics. Parks or open space in Howard County

that was acquired to protect environmental resources may not be suited to intensive

recreational facilities. The potential for recreational activities in such areas may be

limited to low-intensity or passive activities, such as hiking or nature study.

In 1999, Howard County recorded 3,387 acres of parkland, 2,410 acres of open

space, and 1,711 acres of natural resource area. In the same year, there were

20 miles of bike trails, 13 miles of equestrian trails, and 34 miles of hiking trails on

county-owned or leased land. Of the 3,387 acres of parkland in the county, only

889 acres has been developed for active recreational activities.

“The Howard County 1999 Comprehensive Recreation, Parks, and Open Space

Plan” is the county’s primary document for determining needs and standards for

parkland, open space, and recreation. Howard County exceeded the standard

established by the National Recreation and Parks Association (NRPA) by setting

aside more than 60 acres for every 1,000 people; the NRPA advocates 60 acres for

every 1,000 residents be developed for active recreation.

The soils of the survey area are rated in tables 11a and 11b according to

limitations that affect their suitability for recreation. The ratings are both verbal and

numerical. Rating class terms indicate the extent to which the soils are limited by all
Soil Survey of Howard County, Maryland

161

of the soil features that affect the recreational uses. Not limited indicates that the soil

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

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

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

overcome or minimized by special planning, design, or installation. Fair performance

and moderate maintenance can be expected. Very limited indicates that the soil has

one or more features that are unfavorable for the specified use. The limitations

generally cannot be overcome without major soil reclamation, special design, or

expensive installation procedures. Poor performance and high maintenance can be

expected.

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

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

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

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

The ratings in the tables are based on restrictive soil features, such as wetness,

slope, and texture of the surface layer. Susceptibility to flooding is considered. Not

considered in the ratings, but important in evaluating a site, are the location and

accessibility of the area, the size and shape of the area and its scenic quality,

vegetation, access to water, potential water impoundment sites, and access to public

sewer lines. The capacity of the soil to absorb septic tank effluent and the ability of

the soil to support vegetation also are important. Soils that are subject to flooding are

limited for recreational uses by the duration and intensity of flooding and the season

when flooding occurs. In planning recreational facilities, onsite assessment of the

height, duration, intensity, and frequency of flooding is essential.

The information in tables 11a and 11b can be supplemented by other information

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

materials, sanitary facilities, and water management.

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

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

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

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

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

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

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

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

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

camp areas should absorb rainfall readily, remain firm under heavy foot traffic, and

not be dusty when dry. The soil properties that influence trafficability are texture of the

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

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

cemented pan, permeability, and toxic substances in the soil.

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

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

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

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

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

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

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

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

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

cemented pan, permeability, and toxic substances in the soil.

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

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

the ease of developing playgrounds and that influence trafficability and the growth of
Soil Survey of Howard County, Maryland

162

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

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

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

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

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

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

pan, permeability, and toxic substances in the soil.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

matter in the surface layer. The suitability of the soil for traps, tees, roughs, and

greens is not considered in the ratings.

Hydric Soils

Table 12 lists the map unit components that are rated as hydric soils in the survey

area. This list can help in planning land uses; however, onsite investigation is

recommended to determine the hydric soils on a specific site (National Research

Council 1995; Hurt, Whited, and Pringle 2002).

The three essential characteristics of wetlands are hydrophytic vegetation, hydric

soils, and wetland hydrology (Cowardin and others 1979; U.S. Army Corps of

Engineers 1987; National Research Council 1995; Tiner 1985). Criteria for each of the

characteristics must be met for areas to be identified as wetlands. Undrained hydric

soils that have natural vegetation should support a dominant population of ecological

wetland plant species. Hydric soils that have been converted to other uses should be

capable of being restored to wetlands.

Hydric soils are defined by the National Technical Committee for Hydric Soils

(NTCHS) as soils that formed under conditions of saturation, flooding, or ponding

long enough during the growing season to develop anaerobic conditions in the upper

part (Federal Register 1994). These soils are either saturated or inundated long

enough during the growing season to support the growth and reproduction of

hydrophytic vegetation.

The NTCHS definition identifies general soil properties that are associated with

wetness. In order to determine whether a specific soil is a hydric soil or nonhydric

soil, however, more specific information, such as information about the depth and

duration of the water table, is needed. Thus, criteria that identify those estimated soil

properties unique to hydric soils have been established (Federal Register 2002).

These criteria are used to identify a phase of a soil series that normally is associated

with wetlands. The criteria used are selected estimated soil properties that are

described in “Soil Taxonomy” (Soil Survey Staff 1999) and “Keys to Soil Taxonomy”
Soil Survey of Howard County, Maryland

163

(Soil Survey Staff 1998) and in the “Soil Survey Manual” (Soil Survey Division Staff

1993).

If soils are wet enough for a long enough period to be considered hydric, they

should exhibit certain properties that can be easily observed in the field. These visible

properties are indicators of hydric soils. The indicators used to make onsite

determinations of hydric soils in this survey area are specified in “Field Indicators of

Hydric Soils in the United States” (Hurt, Whited, and Pringle 2002).

Hydric soils are identified by examining and describing the soil to a depth of about

20 inches. This depth may be greater if determination of an appropriate indicator so

requires. It is always recommended that soils be excavated and described to the

depth necessary for an understanding of the redoximorphic processes. Then, using

the completed soil descriptions, soil scientists can compare the soil features required

by each indicator and specify which indicators have been matched with the conditions

observed in the soil. The soil can be identified as a hydric soil if at least one of the

approved indicators is present.

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

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

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

lower positions on the landform.

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

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

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

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

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

subgroups that:

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

during the growing season, or

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

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

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

20 inches, or

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

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

depth of 20 inches, or

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

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

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

season.

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

season.

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
Soil Survey of Howard County, Maryland

164

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

the mapped areas of a specific soil.

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

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

design and construction of engineering works.

Government ordinances and regulations that restrict certain land uses or impose

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

section. Local ordinances and regulations should be considered in planning, in site

selection, and in design.

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

determining the ratings in this section. During the fieldwork for this soil survey,

determinations were made about particle-size distribution, liquid limit, plasticity index,

soil reaction, depth to bedrock, hardness of bedrock within 5 to 7 feet of the surface,

soil wetness, depth to a water table, ponding, slope, likelihood of flooding, natural soil

structure aggregation, and soil density. Data were collected about kinds of clay

minerals, mineralogy of the sand and silt fractions, and the kinds of adsorbed cations.

Estimates were made for erodibility, permeability, corrosivity, shrink-swell potential,

available water capacity, and other behavioral characteristics affecting engineering

uses.

This information can be used to evaluate the potential of areas for residential,

commercial, industrial, and recreational uses; make preliminary estimates of

construction conditions; evaluate alternative routes for roads, streets, highways,

pipelines, and underground cables; evaluate alternative sites for sanitary landfills,

septic tank absorption fields, and sewage lagoons; plan detailed onsite investigations

of soils and geology; locate potential sources of gravel, sand, earthfill, and topsoil;

plan drainage systems, irrigation systems, ponds, terraces, and other structures for

soil and water conservation; and predict performance of proposed small structures

and pavements by comparing the performance of existing similar structures on the

same or similar soils.

The information in the tables, along with the soil maps, the soil descriptions, and

other data provided in this survey, can be used to make additional interpretations.

Some of the terms used in this soil survey have a special meaning in soil science

and are defined in the Glossary.

Building Site Development

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

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

and maintenance. Tables 13a and 13b 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
Soil Survey of Howard County, Maryland

165

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

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

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

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

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

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

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

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

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

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

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

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

Compressibility is inferred from the Unified classification. The properties that affect

the ease and amount of excavation include depth to a water table, ponding, flooding,

slope, depth to bedrock or a cemented pan, hardness of bedrock or a cemented pan,

and the amount and size of rock fragments.

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

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

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

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

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

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

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

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

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

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

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

amount and size of rock fragments.

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

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

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

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

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

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

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

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

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

from the AASHTO group index number), subsidence, linear extensibility (shrink-swell

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

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

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

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

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

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

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

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

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

potential) influence the resistance to sloughing.

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

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

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

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

depth to a water table; ponding; depth to bedrock or a cemented pan; the available
Soil Survey of Howard County, Maryland

166

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 14a and 14b show the degree and kind of soil limitations that affect septic

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

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

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

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

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

that the soil has features that are moderately favorable for the specified use. The

limitations can be overcome or minimized by special planning, design, or installation.

Fair performance and moderate maintenance can be expected. Very limited indicates

that the soil has one or more features that are unfavorable for the specified use. The

limitations generally cannot be overcome without major soil reclamation, special

design, or expensive installation procedures. Poor performance and high

maintenance can be expected.

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

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

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

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

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

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

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

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

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

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

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

Subsidence interferes with installation and maintenance. Excessive slope may cause

lateral seepage and surfacing of the effluent in downslope areas.

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

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

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

ground water may become contaminated.

Sewage lagoons are shallow ponds constructed to hold sewage while aerobic

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

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

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

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

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

stones, and content of organic matter.

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

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

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

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

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

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

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

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

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.
Soil Survey of Howard County, Maryland

168

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

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

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

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

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

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

too acid.

Construction Materials

Tables 15a and 15b give information about the soils as potential sources of

gravel, sand, topsoil, reclamation material, and roadfill. 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. Specifications

for each use vary widely. In table 15a, only the likelihood of finding material in suitable

quantity is evaluated. The suitability of the material for specific purposes is not

evaluated, nor are factors that affect excavation of the material. The properties used

to evaluate the soil as a source of sand or gravel are gradation of grain sizes (as

indicated by the Unified classification of the soil), the thickness of suitable material,

and the content of rock fragments. If the bottom layer of the soil contains sand or

gravel, the soil is considered a likely source regardless of thickness. The assumption

is that the sand or gravel layer below the depth of observation exceeds the minimum

thickness.

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

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

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

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

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

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

which the layer is a likely source.

The soils are rated good, fair, or poor as potential sources of topsoil, reclamation

material, and roadfill. The features that limit the soils as sources of these materials

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

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

reclamation material, or roadfill. The lower the number, the greater the limitation.

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.

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
Soil Survey of Howard County, Maryland

169

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).

Water Management

Table 16 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 tables indicate the severity of individual limitations. The

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

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

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

(0.00).

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

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

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

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

area.

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

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

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

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

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

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

construction.

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

Soil properties to a depth even greater than the height of the embankment can affect
Soil Survey of Howard County, Maryland

170

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.
171

Soil Survey of Howard County, Maryland

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. If

the content of particles coarser than sand is 15 percent or more, an appropriate

modifier is added, for example, “gravelly.” Textural terms are defined in the Glossary.

Classification of the soils is determined according to the Unified soil classification

system (ASTM 2005) and the system adopted by the American Association of State

Highway and Transportation Officials (AASHTO 2004).

The Unified system classifies soils according to properties that affect their use as

construction material. Soils are classified according to particle-size distribution of the

fraction less than 3 inches in diameter and according to plasticity index, liquid limit,

and organic matter content. Sandy and gravelly soils are identified as GW, GP, GM,

GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, OL, MH, CH, and OH; and

highly organic soils as PT. Soils exhibiting engineering properties of two groups can

have a dual classification, for example, CL-ML.

The AASHTO system classifies soils according to those properties that affect

roadway construction and maintenance. In this system, the fraction of a mineral soil

that is less than 3 inches in diameter is classified in one of seven groups from A-1

through A-7 on the basis of particle-size distribution, liquid limit, and plasticity index.

Soils in group A-1 are coarse grained and low in content of fines (silt and clay). At the

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

in group A-8 on the basis of visual inspection.

Soil Properties
Soil Survey of Howard County, Maryland

172

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.

Particle size is the effective diameter of a soil particle as measured by

sedimentation, sieving, or micrometric methods. Particle sizes are expressed as

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

silt, and clay, ranging from the larger to the smaller.

Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter to

2 millimeters in diameter. In table 18, the estimated sand content of each soil layer is

given as a percentage, by weight, of the soil material that is less than 2 millimeters in

diameter.

Silt as a soil separate consists of mineral soil particles that are 0.002 to

0.05 millimeter in diameter. In table 18, the estimated silt content of each soil layer is

given as a percentage, by weight, of the soil material that is less than 2 millimeters in

diameter.

Clay as a soil separate consists of mineral soil particles that are less than

0.002 millimeter in diameter. In 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 content of sand, silt, and clay affects the physical behavior of a soil. Particle

size is important for engineering and agronomic interpretations, for determination of

soil hydrologic qualities, and for soil classification.

The amount and kind of clay affect the fertility and physical condition of the soil and

the ability of the soil to adsorb cations and to retain moisture. They influence shrinkswell potential, permeability, plasticity, the ease of soil dispersion, and other soil
Soil Survey of Howard County, Maryland

173

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

operations.

Moist bulk density is the weight of soil (ovendry) per unit volume. Volume is

measured when the soil is at field moisture capacity, that is, the moisture content at

1

/3- or 1/10-bar (33kPa or 10kPa) moisture tension. Weight is determined after the soil

is dried at 105 degrees C. In the table, the estimated moist bulk density of each soil

horizon is expressed in grams per cubic centimeter of soil material that is less than

2 millimeters in diameter. Bulk density data are used to compute shrink-swell

potential, available water capacity, total pore space, and other soil properties. The

moist bulk density of a soil indicates the pore space available for water and roots.

Depending on soil texture, a bulk density of more than 1.4 can restrict water storage

and root penetration. Moist bulk density is influenced by texture, kind of clay, content

of organic matter, and soil structure.

Permeability (Ksat ) refers to the ability of a soil to transmit water or air. The term

“permeability,” as used in soil surveys, indicates saturated hydraulic conductivity

(Ksat ). The estimates in the table indicate the rate of water movement, in inches per

hour, when the soil is saturated. They are based on soil characteristics observed in

the field, particularly structure, porosity, and texture. Permeability is considered in the

design of soil drainage systems and septic tank absorption fields.

Available water capacity refers to the quantity of water that the soil is capable of

storing for use by plants. The capacity for water storage is given in inches of water per

inch of soil for each soil layer. The capacity varies, depending on soil properties that

affect retention of water. The most important properties are the content of organic

matter, soil texture, bulk density, and soil structure. Available water capacity is an

important factor in the choice of plants or crops to be grown and in the design and

management of irrigation systems. Available water capacity is not an estimate of the

quantity of water actually available to plants at any given time.

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

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

change between the water content of the clod at 1/3- or 1/10-bar tension (33kPa or

10kPa tension) and oven dryness. The volume change is reported in the table as

percent change for the whole soil. Volume change is influenced by the amount and

type of clay minerals in the soil.

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

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

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

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

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

needed.

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 the table as the K factor (Kw and Kf) and the T factor.

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

water. Factor K is one of several 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
Soil Survey of Howard County, Maryland

174

being equal, the higher the value, the more susceptible the soil is to sheet and rill

erosion by water.

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

modified by the presence of rock fragments.

Erosion factor Kf indicates the erodibility of the fine-earth fraction, or the material

less than 2 millimeters in size.

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

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

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

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

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

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

susceptible. The groups are as follows:

1. Coarse sands, sands, fine sands, and very fine sands.

2. Loamy coarse sands, loamy sands, loamy fine sands, loamy very fine sands,

ash material, and sapric soil material.

3. Coarse sandy loams, sandy loams, fine sandy loams, and very fine sandy

loams.

4L. Calcareous loams, silt loams, clay loams, and silty clay loams.

4. Clays, silty clays, noncalcareous clay loams, and silty clay loams that are more

than 35 percent clay.

5. Noncalcareous loams and silt loams that are less than 20 percent clay and

sandy clay loams, sandy clays, and hemic soil material.

6. Noncalcareous loams and silt loams that are more than 20 percent clay and

noncalcareous clay loams that are less than 35 percent clay.

7. Silts, noncalcareous silty clay loams that are less than 35 percent clay, and

fibric soil material.

8. Soils that are not subject to wind erosion because of rock fragments on the

surface or because of surface wetness.

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 milliquivalents per 100 grams of soil at neutrality

(pH 7.0) or at some other stated pH value. Soils having a low cation-exchange

capacity hold fewer cations and may require more frequent applications of fertilizer

than soils having a high cation-exchange capacity. The ability to retain cations

reduces the hazard of ground-water pollution.

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

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

for soils that have pH of less than 5.5.

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

based on many field tests. For many soils, values have been verified by laboratory
Soil Survey of Howard County, Maryland

175

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.

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

long-duration storms.

The four hydrologic soil groups are:

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

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

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

Group B. Soils having a moderate infiltration rate when thoroughly wet. These

consist chiefly of moderately deep or deep, moderately well drained or well drained

soils that have moderately fine texture to moderately coarse texture. These soils have

a moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when thoroughly wet. These consist

chiefly of soils having a layer that impedes the downward movement of water or soils

of moderately fine texture or fine texture. These soils have a slow rate of water

transmission.

Group D. Soils having a very slow infiltration rate (high runoff potential) when

thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential,

soils that have a high water table, soils that have a claypan or clay layer at or near the

surface, and soils that are shallow over nearly impervious material. These soils have

a very slow rate of water transmission.

Surface runoff refers to the loss of water from an area by flow over the land

surface. Surface runoff classes are based on slope, climate, and vegetative cover. It is

assumed that the surface of the soil is bare and that the retention of surface water

resulting from irregularities in the ground surface is minimal. The classes are

negligible, very low, low, medium, high, and very high.

The months in the table indicate the portion of the year in which the feature is most

likely to be a concern.

Water table refers to a saturated zone in the soil. The table indicates, by month,

depth to the top (upper limit) and base (lower limit) of the saturated zone in most

years. Estimates of the upper and lower limits are based mainly on observations of

the water table at selected sites and on evidence of a saturated zone, namely grayish

colors or mottles (redoximorphic features) in the soil. A saturated zone that lasts for

less than a month is not considered a water table.

Ponding is standing water in a closed depression. Unless a drainage system is

installed, the water is removed only by percolation, transpiration, or evaporation. 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
Soil Survey of Howard County, Maryland

176

or snowmelt is not considered flooding, and water standing in swamps and marshes

is considered ponding rather than flooding.

Duration and frequency are estimated. Duration is expressed as extremely brief if

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

30 days, and very long if more than 30 days. Frequency is expressed as none, very

rare, rare, occasional, frequent, and very frequent. None means that flooding is not

probable; very rare that it is very unlikely but possible under extremely unusual

weather conditions (the chance of flooding is less than 1 percent in any year); rare

that it is unlikely but possible under unusual weather conditions (the chance of

flooding is 1 to 5 percent in any year); occasional that it occurs infrequently under

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

frequent that it is likely to occur often under normal weather conditions (the chance of

flooding is more than 50 percent in any year but is less than 50 percent in all months

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

weather conditions (the chance of flooding is more than 50 percent in all months of

any year).

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

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

content with increasing depth; and little or no horizon development.

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

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

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

engineering surveys that delineate flood-prone areas at specific flood frequency

levels.

Soil Features

Table 21 gives estimates of various soil features. The estimates are used in land

use planning that involves engineering considerations.

A restrictive layer is a nearly continuous layer that has one or more physical,

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

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

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

layers. The table indicates the hardness and thickness of the restrictive layer, both of

which significantly affect the ease of excavation. Depth to top is the vertical distance

from the soil surface to the upper boundary of the restrictive layer.

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
Soil Survey of Howard County, Maryland

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.

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

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

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

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

soils or miscellaneous areas are somewhat similar in all areas.

Concretions. Cemented bodies with crude internal symmetry organized around a

point, a line, or a plane. They typically take the form of concentric layers visible to

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

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

rotations that contain grasses and legumes and the return of crop residue to the

soil. Other practices include the use of green manure crops of grasses and

legumes, proper tillage, adequate fertilization, and weed and pest control.

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

protective amount of crop residue on the surface throughout the year.
Soil Survey of Howard County, Maryland

184

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

and its resistance to deformation when ruptured. Consistence includes resistance

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

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

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

Survey Manual.”

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.

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.

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.

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.

conforming to the dip of the underlying bedrock.
Soil Survey of Howard County, Maryland

185

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

downslope areas by diverting runoff from its natural course.

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

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

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

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

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

to permit a full stripcropping pattern to be used.

Drainage class (natural). Refers to the frequency and duration of wet periods under

conditions similar to those under which the soil formed. Alterations of the water

regime by human activities, either through drainage or irrigation, are not a

consideration unless they have significantly changed the morphology of the soil.

Seven classes of natural soil drainage are recognized—excessively drained,

somewhat excessively drained, well drained, moderately well drained, somewhat

poorly drained, poorly drained, and very poorly drained. These classes are

defined in the “Soil Survey Manual.”

produce a distinct natural plant community. An ecological site is the product of

all the environmental factors responsible for its development. It is typified by an

association of species that differ from those on other ecological sites in kind

and/or proportion of species or in total production.

Eluviation. The movement of material in true solution or colloidal suspension

from one place to another within the soil. Soil horizons that have lost

younger and lower alluvial surfaces.

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.

Fill slope. A sloping surface consisting of excavated soil material from a road cut. It

commonly is on the downhill side of the road.

(300 meters) and fringes a mountain range or high-plateau escarpment.

Footslope. The position that forms the inner, gently inclined surface at the base of a

hillslope. In profile, footslopes are commonly concave. A footslope is a transition

zone between upslope sites of erosion and transport (shoulders and backslopes)

and downslope sites of deposition (toeslopes).

given physical and biological factors by which it may be differentiated from other

stands.
Soil Survey of Howard County, Maryland

187

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. 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.

Glacial drift. Pulverized and other rock material transported by glacial ice and then

deposited. Also, the sorted and unsorted material deposited by streams flowing

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 miniature valley with steep sides cut by running water and through which

water ordinarily runs only after rainfall. The distinction between a gully and a rill is

one of depth. A gully generally is an obstacle to farm machinery and is too deep

to be obliterated by ordinary tillage; a rill is of lesser depth and can be smoothed

over by ordinary tillage.

Hard bedrock. Bedrock that cannot be excavated except by blasting or by the use of

special equipment that is not commonly used in construction.

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.

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.

Head out. To form a flower head.

Head slope. A geomorphic component of hills consisting of a laterally concave area

of a hillside, especially at the head of a drainageway. The overland waterflow is

converging.

Hemic soil material (mucky peat). Organic soil material intermediate in degree of

decomposition between the less decomposed fibric material and the more

decomposed sapric material.

managed, residue from these crops can be used to control erosion until the next
Soil Survey of Howard County, Maryland

188

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

matter to the soil.

Hill. A natural elevation 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; hillsides generally have slopes of more than 15 percent. The

distinction between a hill and a mountain is arbitrary and is dependent on local

usage.

Horizon, soil. A layer of soil, approximately parallel to the surface, having distinct

characteristics produced by soil-forming processes. In the identification of soil

horizons, an uppercase letter represents the major horizons. Numbers or

lowercase letters that follow represent subdivisions of the major horizons. An

explanation of the subdivisions is given in the “Soil Survey Manual.” The major

horizons of mineral soil are as follows:

O horizon.—An organic layer of fresh and decaying plant residue.

A horizon.—The mineral horizon at or near the surface in which an accumulation

of humified organic matter is mixed with the mineral material. Also, a plowed

surface horizon, most of which was originally part of a B horizon.

E horizon.—The mineral horizon in which the main feature is loss of silicate clay,

iron, aluminum, or some combination of these.

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

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

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

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

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

these.

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

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

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

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

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

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

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

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

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

mineral soils.

Hydrologic soil groups. Refers to soils grouped according to their runoff potential.

The soil properties that influence this potential are those that affect the minimum

rate of water infiltration on a bare soil during periods after prolonged wetting

when the soil is not frozen. These properties are depth to a seasonal high water

table, the infiltration rate and permeability after prolonged wetting, and depth to a

very slowly permeable layer. The slope and the kind of plant cover are not

considered but are separate factors in predicting runoff.

Igneous rock. Rock formed by solidification from a molten or partially molten state.

Major varieties include plutonic and volcanic rock. Examples are 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.

Increasers. Species in the climax vegetation that increase in amount as the more

desirable plants are reduced by close grazing. Increasers commonly are the

shorter plants and the less palatable to livestock.
Soil Survey of Howard County, Maryland

189

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

 * 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 (40 degrees F).

* Explanation of hydric criteria codes:

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

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

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

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

 during the growing season, or

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

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

 textures are coarse sand, sand, or fine sand in all layers within a depth

 of 20 inches, or

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

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

 depth of 20 inches, or

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

 if permeability is less than 6.0 in/hr in any layer within a depth of

 20 inches.

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

 season.

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

 season.

Table 15a.--Construction Materials (Part 1)

(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. See text

 for further explanation of ratings in this table.)
