Contour Farming on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 330

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP330), Contour Farming (CF) on agricultural land by county. Contour Farming is described as "tillage, planting, and other farming operations performed on or near the contour of the field slope." (U.S. Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools. The acres on which CF's are applied were totaled at the county level in the tabular NRI database and then apportioned to a raster coverage of agricultural land within the county based on the Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover grids (Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not record information on those lands.
