As much as a third of the topsoil in the corn belt may be gone

The corn belt, which stretches from western Illinois to the Dakotas, produces billions of bushels of corn, soybeans and other grains annually.

The study concluded that fertile soil has been destroyed not as a result of natural wind and water erosion, but by a century of overplowing. (tinyurl.com/wps8c99c)
Topsoil is the “black, organic, [carbon and mineral] rich soil that’s really good for growing crops,” said Evan Thaler, Ph.D. student at UMass. Topsoil accumulates over centuries and is teeming with microorganisms. ....
