Drs. Karl Williard, Jon Schoonover of Southern Illinois University and Gurbir Singh and Gurpreet Kaur from the Delta Research and Extension Center at Mississippi State University had their original research published in Vadose Zone Journal, published by the Soil Science Society of America.
Dr. Shalamar Armstrong’s research near Bloomington, Ill. takes a close look how adjusting N timing overcame the usual yield lag in corn planted into cereal rye cover crop.
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.
How do current recommendations on drainage depth and spacing influence nutrient loss, crop productivity and nutrient utilization?
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.
