Abstract: Nitrogen loss from Illinois' tile drained lands significantly contributes to degraded water quality in the Mississippi River Basin and local water bodies. Denitrifying woodchip bioreactors offer agricultural producers a realistic and cost-effective edge-of-field option to clean nitrate from tile drainage water, but new approaches are required to design them to be more efficient and to manage them for maximized nitrogen removal. This work will improve design and management strategies for woodchip bioreactors by evaluating denitrification potential and nitrous oxide production potential of woodchips, tile drainage water, and soils.
