CSR2 is a Corn Suitability Rating index that rates soil types for their potential row-crop productivity. Previously called CSR, the CSR2 generally provides an index comparable with the original CSR but with greater transparency, consistency and method of calculation. The Natural Resource Conservation Service’s (NRCS) Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA NRCS and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties.

This task sheet demonstrates how to use the WSS to generate CSR2 Reports for Iowa counties.
