Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 05:51 AM | Dataset Last Updated: November 17, 2020 at 12:00 AM
This dataset consists of four national 1-kilometer (km) resolution rasters of the estimated percent presence of the soil restrictive layer (SRL) in the upper 25, 35, 45, and 55 centimeters of agricultural land. These rasters were developed from selected criteria of soil parameters from the Soil Survey Geographical (SSURGO) database and mapped agricultural land from the National Land Cover Database 2001 (NLCD 2001), version 2.
