Increased detection of nitrate and pesticides in surface and ground water has prompted concern about the impact of farming systems on water quality. A number of studies have been incorporated into an analysis of the impact of farming systems on water quality. These studies are being conducted at Treynor on the loess soils and at Ames and Nashua on the glacial till soils. A series of temporal and spatial scales are being addressed through a combination of disciplines at each of these sites. The scope of this project and the experimental plan is described in this report.
