ICM News
By Gerald Miller, Professor Emeritus, and Lee Burras, Professor, Department of Agronomy
The equation for calculating Iowa’s Corn Suitability Ratings (CSR) was recently updated and designated Corn Suitability Rating 2 (CSR2). The updated equation provides every user an opportunity to calculate the rating for each soil map unit identified in Iowa.
Corn Suitability Rating 2 remains an index to the inherent soil productivity of each kind of soil for row crop production. The index is scaled from 100, for the most productive soils, to 5 as the least productive.
