The National Soil Survey Handbook provides the main operational and procedural guidance for conducting the NRCS portion of the National Cooperative Soil Survey program.
NRCS has recently updated soil data for each of the 3,265 soil survey areas mapped over the last 118 years. Spatial (soil polygons) and tabular (physical and chemical properties) data are available from Web Soil Survey.
Web Soil Survey version 3.0 was recently launched. The web-based application provides free soils information along with maps, properties, and interpretations aimed at helping with land use decisions.
