Summary

The water quality of two agricultural watersheds was monitored from 1996 through 2007 to evaluate changes due to differing land-use practices. Both the South Fork Iowa River watershed in Iowa and the Little Cobb River watershed in Minnestoa are located in Des Moines Lobe of the Wisconsinan glacier topographic setting. Fertile soils developed on glacial till have allowed for development of intensive row crop agriculture. More than 85 percent of the watersheds are used for row-crop agriculture. In contrast to the similar intensity of row crop agriculture in the two watersheds, intensity of animal procudtion in the South Fork Iowa River is significantly larger than in the Little Cobb River. Nitrate concentrations from 1996 through 2007 [...]
