National Commodity Crop Productivity Index (NCCPI)
NCCPI is designed to express the inherent capacity of the soils in a given field to produce dryland commodity crops. It was intended to be used in the evaluation of rental payments made on fields enrolled in the Conservation Reserve Program (CRP).
NCCPI values are general guidelines toward soil productivity, but may not completely correlate in all seasons, crops and locations.
User Guide for the National Commodity Crop Productivity Index (NCCPI) Version 2.0, 2012
"The National Commodity Crop Productivity Index (NCCPI) model is a national soil interpretation that is generated in the National Soil Information System (NASIS) environment and is reported in the Soil Data Mart and on Web Soil Survey. It presently deals only with nonirrigated crops, but at a later date it will be expanded to include irrigated crops, rangeland, and forestland productivity. "
