The above picture is from the spring of 2015, and shows soil suspended in the air on a breezy spring morning after the snow had melted.
From NRCS: "Wind erosion - the process of detachment, transport, and deposition of soil by wind." Before the large expansion of corn acres from high crop prices starting in 2008, "Between 1982 and 2007, soil erosion on U.S. cropland decreased 43%. Water (sheet & rill) erosion on cropland in 2007 declined from 1.68 billion tons per year to 960 million tons per year, and erosion due to wind declined from 1.38 billion tons per year to 765 million tons per year" (NRCS).
Future potential additions to this post includes a longer review, impacts of crop management, and current understanding of water and wind erosion rates.
