Dr. Shalamar Armstrong with Purdue University leads this multi-institute research project that closely examines the impact that cereal rye cover crop has on nutrient loss.
A woodchip bioreactors is just one edge-of-field nitrogen management tools that farmers can use to reduce the amount of runoff of lost nutrients.

David and Jim Isermann share research on their farm using struvite as an alternative to traditional phosphorus field applications. Partners from Farm Bureau, Isermann Farms, University of Illinois, Illinois NREC and Soil Health Partnership all play a role in studying the Isermanns’ LaSalle County plot.

Lowell Gentry, Dan Schaefer and Eric Miller are studying how installing a woodchip bioreactor at the edge of a field, along with planting cover crops might limit nutrient loss.
Can drainage depth and spacing be optimized to minimize the nutrient losses and maximize crop production?
It’s not as complicated as it sounds. DNRA conserves Nitrogen within the system. Since DNRA takes nitrate and converts it to ammonium, it does not produce N2 or N2O.
Dr. Laura Christianson, along with her colleagues from the University of Illinois, are exploring various options of drainage water management. “Drain only what is necessary for good trafficability and crop growth — and not a drop more?
Dr. Amir Sadeghpour and research collaborators at SIU and UK are developing regionally-specific algorithms fro Illinois farmers to use GreenSeeker sensor tools.
This study supports the premise that concentrating N fertilizer below ground near the crop row can increase grain yield and N removal.
