The purpose of this research was to examine nitrogen and phosphorus concentrations in runoff at the field-scale level i.e., homogeneous land-use plot over a variety of land-use practices. Land-use practices included animal containmentbarnyard areas, corn production fields, alfalfa and grass hayfields, Conservation Reserve Program CRP fields, and woodlots located in the upper Eau Galle River Watershed, west-central Wisconsin. The watershed is dominated by agricultural and dairy livestock land-use practices. Results from this study will be important in improving watershed modeling capabilities for predicting the runoff of nutrients from complex landscape mosaics.
