Estimates of the Soil Restrictive Layer in the Upper 25,35,45, and 55 centimeters of agricultural land in the conterminous United States

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: February 10, 2026 | Last Modified: 2020-11-17T00:00:00Z
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.
