United States In cooperation Department with Louisiana Soil Survey of of Agriculture Agricultural Natural Experiment Resources Station and Conservation the Louisiana Acadia Parish, Service Soil and Water Conservation Committee Louisiana iii 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. iv 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 Station, and local agencies. The Natural Resources Conservation Service has leadership for the Federal part of the National Cooperative Soil Survey. Major fieldwork for this soil survey was completed in 1996. Soil names and descriptions were approved in 2000. Unless otherwise indicated, statements in this publication refer to conditions in the survey area in 1996. This survey was made cooperatively by the Natural Resources Conservation Service and the Louisiana Agricultural Experiment Station and the Louisiana Soil and Water Conservation Committee. The survey is part of the technical assistance furnished to the Acadia 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.
