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.
Arsenic occurs naturally in soil and minerals and is commonly found in groundwater throughout much of Minnesota. The occurrence and distribution of arsenic in groundwater is difficult to predict. Research is steadily increasing our understanding of the mechanisms and geologic conditions that determine arsenic occurrence in groundwater. The arsenic concentration in a new well, measured at the time of construction, is sometimes higher or lower, compared to subsequent sampling results.
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.
This project will complete a Acetochlor Impairment Response Report. This report will combine and coordinate information relating to actions being done in direct response to the acetochlor water quality impairments with those being done and support MDA’s on-going responsibility to assure pesticides are used in a manner that does not cause unreasonable adverse effects on the environment.
