How to Use This Soil Survey
General Soil Map
The general soil map, which is a color map, shows the survey area divided into groups of associated soils called
general soil map units. This map is useful in planning the use and management of large areas.
To find information about your area of interest, locate that area on the map, identify the name of the map unit in the
area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of
the soils in your area.
Detailed Soil Maps
The detailed soil maps can be useful in planning the use and
management of small areas.
To find information about your area
of interest, locate that area on the
Index to Map Sheets. Note the
number of the map sheet and turn
to that sheet.
Locate your area of interest on
the map sheet. Note the map unit
symbols that are in that area. Turn
to the Contents, which lists the
map units by symbol and name
and shows the page where each
map unit is described.
The Contents shows which table
has data on a specific land use for
each detailed soil map unit. Also
see the Contents for sections of
this publication that may address
your specific needs.

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 1989. Soil names and
descriptions were approved in 1989. Unless otherwise indicated, statements in this
publication refer to conditions in the survey area in 1989. This survey was made
cooperatively by the Natural Resources Conservation Service, the Louisiana
Agricultural Experiment Station, and the Louisiana Soil and Water Conservation
Committee. The survey is part of the technical assistance furnished to the Gulf Coast
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: Rice, which is a major crop in Jefferson Davis Parish, is being harvested in an area of
Crowley-Vidrine silt loam, 0 to 1 percent slopes.
