Percent of Agriculture Land Subject to Select National Resource Inventory Conservation Practices, 2000-2012

This metadata record describes 26 30-meter raster data sets that estimate the percent of agricultural land that may be subject to select conservation practices for each year during the period 2000-2012. The data were derived from U.S. Department of Agriculture (USDA) National Resources Conservation Service (NRCS) National Resource Inventory (NRI). One set of rasters (denoted by the ICP prefix) represents an estimate of the percent of agricultural land potentially subject to Alley Cropping, Contour Buffer Strips, Contour Farming, Contour Orchard/Other Fruit Area, Cross Wind Trap Strips, Field Border, Filter Strip, Grassed Waterway, Hedgerow Planting, Herbaceous Wind Barriers, Irrigation System, Tailwater Recovery, Riparian Forest Buffer, Stripcroppings, Terrace, Tree/Shrub Establishment, and Windbreak/Shelterbelt Establishment practices. The other set (denoted by the WCP prefix) represents the estimated percent of agricultural land potentially subject to Bedding, Hillside Ditch, Surface Drainage, Field Ditch, and Water and Sediment Control Basin practices. These grouped practices were then processed into 26 separate national 30-meter rasters (16 years x 2 practice types) as described in the process steps of this metadata record. These conservation practice data are estimated areas protected by a conservation practice and not an actual conservation practice footprint. Summaries that could possibly reveal the location and/or identity of an NRI sample site may not be published.
