The Clay County Drainage Site is designed to evaluate the environmental impact of both surface and subsurface drainage from agricultural fields. This site includes six subsurface plots and one surface runoff plot, each approximately 24 acres in size. Monitoring stations are fully automated and each individual plot is monitored separately.The soils and topography across this demonstration site are virtually identical and represent field characteristics common in the most productive agricultural areas of the Red River Valley.
The Discovery Farms program is a farmer-led effort to gather information on soil and nutrient loss on farms in different settings across Minnesota. The mission of Discovery Farms Minnesota is to gather water quality information under real-world conditions.
