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.
Funding supports an Irrigation Specialist to develop guidance and provide education on irrigation and nitrogen best management practices (BMPs). In this position, Dr. Vasu Sharma provides direct support to irrigators on issues of irrigation scheduling and soil water monitoring. She is collaborating on the development of new irrigation scheduling tools that help irrigators manage water and nitrogen resources more precisely. These tools help reduce nitrogen leaching losses in irrigated cropping systems.
The Minnesota Department of Agriculture (MDA) has partnered with the East Otter Tail Soil and Water Conservation District (EOT SWCD) to carry out a series of workshops and expand programs that promote proper water and nitrogen management.
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.
