Many other references with historical soil erosion information have been compiled by Sundquist (2005). Between 1982 and 2003, total soil erosion on all cropland and CRP land in the United States decreased from over 3 billion tons per year to 1.7 billion tons (Table 3). This is a decrease of nearly 43 percent.There are several likely reasons for this decline.ata from the 2003 Annual NRI, the most up-to-date NRI information available, indicate that average soil erosion rates on all cropland and CRP land have decreased more than 38 percent since 1982. In 2003, the soil erosion rate was estimated at 4.5 tons per acre per year, compared to 7.3 tons per acre per year in 1982.
