Discovery Farms concluded monitoring agricultural tile drainage systems in northeastern Wisconsin and Minnesota in 2020. The goal of the project is to better understand the timing and mechanisms for soil and nutrient loss through tile systems. A full report of the three-year project is in the works and will be published in 2021.
Monitoring in Wisconsin took place in Shawano, Brown, Manitowoc, Kewaunee, and Door Counties at 24 sites.
