2010 Soil Erosion Trends

In Montana, soil erosion levels have remained relatively stable for the past 8 years. There was very little change in cropland erosion rates between 2007 and 2010.

graphical representation of data described in following paragraph

Soil erosion on cropland in Montana decreased between 1982 and 2010. In 1982, the average annual soil erosion on cropland was 10.5 tons/acre/year. Of this 10.5 tons/acre/year of soil loss, 8.1 tons/acre/year was the result of erosion by wind and 2.4 tons/acre/year was a result of water erosion (sheet and rill). In 1987, the average annual soil erosion on cropland was 11.2 tons/acre/year. Of this 11.2 tons/acre/year of soil loss, 8.9 tons/acre/year was the result of erosion by wind and 2.3 tons/acre/year was a result of water erosion (sheet and rill). In 1992, the average annual soil erosion on cropland was 9.6 tons/acre/year. Of this 9.6 tons/acre/year of soil loss, 7.2 tons/acre/year was the result of erosion by wind and 2.4 tons/acre/year was a result of water erosion (sheet and rill). In 1997, the average annual soil erosion on cropland was 6.3 tons/acre/year. Of this 6.3 tons/acre/year of soil loss, 4.0 tons/acre/year was the result of erosion by wind and 2.3 tons/acre/year was a result of water erosion (sheet and rill). In 2002, the average annual soil erosion on cropland was 5.9 tons/acre/year. Of this 5.9 tons/acre/year of soil loss, 3.8 tons/acre/year was the result of erosion by wind and 2.1 tons/acre/year was a result of water erosion (sheet and rill). In 2007, the average annual soil erosion on cropland was 5.8 tons/acre/year. Of this 5.8 tons/acre/year of soil loss, 3.9 tons/acre/year was the result of erosion by wind and 1.9 tons/acre/year was a result of water erosion (sheet and rill). In 2010, the average annual soil erosion on cropland was 5.7 tons/acre/year. Of this 5.7 tons/acre/year of soil loss, 3.8 tons/acre/year was the result of erosion by wind and 1.9 tons/acre/year was a result of water erosion (sheet and rill).
