The UW-Madison Division of Extension Discovery Farms Program installed eight lysimeters on a Pepin County Dairy farm in the fall of 2021 that will remain for at least 3 years. These lysimeters capture water flowing beyond the root zone on its way to groundwater. This study will get an in-depth comparison of the ability of a conservation practice to mitigate nitrate leaching to groundwater. Watch this video, and the rest of the videos in this series for a full picture of how this project works and why it is important.
