Estimates from this model, the erosion productivity impact calculator (EPIC), show that if cropping patterns and the mix of management, tillage, and conservation practices inventoried in the 1982 National Resources Inventory are continued for 100 years, sheet and rill erosion and wind erosion will exceed erosion tolerance on 127 million acres and 64 millionCollection: Reprints Collection
