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 goals of the program are to evaluate the effectiveness of agricultural conservation practices, identify underlying processes that affect water quality, and develop technologies to target critical areas of the landscape. Funded projects provide current and accurate scientific data on the environmental impacts of agricultural practices and help to develop or revise agricultural practices that reduce environmental impacts while maintaining farm profitability.
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.

The objectives of this study were to examine ditch sediment and water samples for the presence and numbers of E.coli and to determine what proportion of the E.coli were stable member of the microbial community (i.e. indigenous to the sites) and what proportion were likely transient or only present because of run-off. Researchers used sophisticated DNA technology to determine the potential sources of E.coli present in the ditch sediment and water samples.
The Nitrogen Fertilizer Management Plan (NFMP) recognizes that existing best management practices (BMPs) may not adequately protect the groundwater from nitrate contamination in some geologic sensitive areas. The NFMP introduces the concept of alternative management tools (AMTs), which are advanced practices that may be required to protect groundwater or mitigate groundwater contamination.
The objective of the project is to demonstrate controlled drainage and saturated buffers as flood mitigation practices as well as their water quality and quantity benefits. The project is intended to set a compelling example to increase the acceptance and adoption of drainage water management practices in the Red River Valley.Surface and subsurface runoff will be monitored, and water samples will be collected and analyzed for nitrate-nitrogen. Installations were completed in 2015-2016.
The Root River Field to Stream Partnership is comprised of farmers, the Minnesota Department of Agriculture, the Minnesota Agricultural Water Resource Center, The Nature Conservancy, Fillmore and Mower County Soil and Water Conservation Districts, the Root River SWCD, Monsanto and academic researchers.Together, project partners are addressing the following key questions:What is the range of sediment, nitrogen and phosphorus losses from agricultural fields on real farms in southeast Minnesota?What are the long-term trends and relationships between specific farming practices and water qualit
