In this project our team set out to quantify the individual and cumulative impacts of select in-field, edge-of-field and beyond-the-field/in-stream management practices on water quantity and water quality for a small watershed and upscale these results to watershed scale (HUC 8). To accomplish this task we designed an experiment within a small watershed at the University of Minnesota Southwest Research and Outreach Center near Lamberton, MN. Our goals were to measure individual and cumulative response of cover cropping, bioreactors, constructed wetlands and drainage ditch management on water and nutrient (nitrogen and phosphorus) loss within a small agricultural watershed. Another goal was to use data from our experimental site coupled with actual on-farm management data from farms in the Cottonwood River Watershed that are enrolled in the Minnesota Agricultural Water Quality Certification Program (MAWQCP).
