How to Use This Soil Survey
General Soil Map
The general soil map, which is the color map preceding the detailed soil maps, 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 follow the
general soil map. These 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,
which precedes the soil maps.
Note the number of the map
sheet and turn to that sheet.
Locate your area of interest on
the map sheet. Note the map
units symbols that are in that
area. Turn to the Contents, which
lists the map units by symbol and
name and shows the page where
each map unit is described.
The Contents shows which table has data on a specific land use for each detailed soil map unit. Also see the
Contents for sections of this publication that may address your specific needs.

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 1998. Soil names and
descriptions were approved in 1998. Unless otherwise indicated, statements in this
publication refer to conditions in the survey area in 1998. This survey was made
cooperatively by the Natural Resources Conservation Service, the Alabama Agricultural
Experiment Station, the Alabama Cooperative Extension System, the Alabama Soil and
Water Conservation Committee, and the Alabama Department of Agriculture and
Industries. The survey is part of the technical assistance furnished to the Choctaw
County Soil and Water 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: Mt. Ararat, in the east-central part of the county, overlooks large expanses of
woodland. Woodland covers about 87 percent of the county. The forest industry is the backbone
of the local economy.
