USER NOTES:
The data are designed to provided a guidance for the use of soils at the county level. The data contain both estimated and measured data on the physical and chemical soil properties and soil interpretations for engineering, water management, recreation, agronomic, woodland, range, and wildlife uses of the soil.
The SSOILS data base provides the most detailed level of information and was designed primarily for farm and ranch, landowner/user, township, county, or parish natural resource planning and management. Using the soil attributes, this data base serves as an excellent source for determining erodible areas and developing erosion control practices; reviewing site development proposals and land use potential; making land use assessments and chemical fate assessments; and identifying potential wetlands and sand and gravel aquifer areas.
The following attribute tables are included:
*comp (map unit component) - stores soil component
information
*compyld (component crop yield) - stores crop yield information
for soil components
*forest (forest understory) - stores information for plant
cover as forest understory
for soil components
*interp (interpretation) - stores soil interpretation
ratings (both limitation
ratings and suitability
ratings) for soil components
*layer (soil layer) - stores characteristics of soil
layers for soil components
*mapunit (map unit) - stores information that
applies to all components of a
soil map unit
*windbrk (windbreak) - stores information on
recommended windbreak
plants for soil components
*wlhabit (wildlife habitat) - stores wildlife habitat
information for soil
components
*woodland(woodland) - stores information on common
indicator trees for soil
components
*woodmgt (woodland management) - stores woodland management
information for soil
components
The spatial data base will be updated when the information becomes available.

DATA LINEAGE SUMMARY:
Using NCSS mapping standards, soil maps in the SSOILS data base are made using field methods. Surveyors observe soils along delineation boundaries and determine map unit composition by field traverses and transects. Aerial photographs are interpreted and used as the field map base. Maps are made at scales ranging from 1:12,000 to 1:63,360. Typically scales are 1:15,840, 1:20,000, or 1:24,000. The maps, along with comprehensive descriptions, produce an attribute and spatial data base for NCSS publications.
