Cost of Erosion
One of the problems we have in selling erosion control is that most farmers do not notice the change from one year to the next. Iowa State University recently estimated the value of the nutrients lost by erosion. Their estimates are based on the organic matter levels in the soil. They estimate that the erosion can cause at much as $50 loss in a year at a rather modest loss level of 5 tons per acre.
