Midwestern US has lost 57.6 billion metric tons of soil due to agricultural practices

Read the full story from the University of Massachusetts Amherst.

A new study in the journal Earth’s Future led by the University of Massachusetts Amherst shows that, since Euro-American settlement approximately 160 years ago, agricultural fields in the midwestern U.S. have lost, on average, two millimeters of soil per year. This is nearly double the rate of erosion that the USDA considers sustainable. Furthermore, USDA estimates of erosion are between three and eight times lower than the figures reported in the study. Finally, the study’s authors conclude that plowing, rather than the work of wind and water, is the major culprit.
