资源简介：
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.
