Project Overview

Agricultural drainage is very prevalent practice in Dodge County and there is a need to implement practices to that will better manage flow and pollutant loads that are being contributed to nearby surface waters. This project involves the installation of a woodchip bioreactor on a tile-drained agricultural field, which will feature improvements in design, and monitoring scope, as compared to a previous bioreactor constructed in Dodge County in 2007. The bioreactor for this project will demonstrate a cost-effective way for agricultural producers to reduce the nitrate level of tile discharge water, and further the understanding of how these same units can aid in phosphorous management, as well.
