The National Commodity Crop Productivity Index (NCCPI) is a model that uses inherent soil properties, landscape features, and climatic characteristics to assign ratings for dry-land commodity crops such as wheat, cotton, sorghum, corn, soybeans, and barley. The model arrays Soil Survey Geographic Database map unit components from 0.01 to 1.0; components with the most desirable soil properties, landscape features, and climatic characteristics will display larger NCCPI values than soils with less desirable traits. The maps presented above are part of the Detailed Soil Survey Atlas, a national collection of state-centered maps prepared at a scale of 1:500,000 derived from U.S. Department of Agriculture soil geographic databases.
