Erosion in Iowa is likely worse than previous estimates.
We already knew part the story: swept away by wind and heavy rains, Iowa’s rich soil is disappearing at an alarming rate, stripping the land of its fertility and polluting the state’s waters.
We just didn’t know how serious the problem has become.
Government estimates had put Iowa’s yearly erosion rate at about 5 tons of soil per acre, and more recent data from Iowa State’s Daily Erosion Project pegged that rate much higher – up to 12 times as high in some areas of the state.
