USER NOTES:

This coverage contains estimates of land in agricultural production in counties in the conterminous United States as reported in the 1987 Census of Agriculture (U.S. Department of Commerce, 1989a). Land in agriculture data are reported as either a number (for example, number of Farms), acres, or as a percentage of county area. Land in agriculture estimates were generated from surveys of all farms where $1,000 or more of agricultural products were sold, or normally would have been sold, during the census year.

Most of the attributes summarized represent 1987 data, but some information for the 1982 Census of Agriculture also was included.

FGDL QUALITY ASSURANCE STATUS:

Dropped the following items: ST (state), PLYTYPE, WORKB. These items were for USGS internal use only.
Renamed CNTYNAME to CNTY_NAME
Renames AREA.ACRES to AREA_ACRES
Added items HECTARES and DESCRIPT
