How cover crops, along with nitrogen timing, affected yield in tile-drained fields
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.
Is Cereal Rye before Corn Recommended?
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.

How Effective are Wetlands for Nutrient Removal?
Small tile-treatment wetlands can offer a practical, long-term edge of field solution to the challenge of reducing nutrient losses from cropland tile drainage runoff.

How do Woodchip Bioreactors Work?
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.
Combining Cover Crops with a Woodchip Bioreactor for Lower Nitrate Loss
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.
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?
What is DNRA?
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.
What is Drainage Water Management?
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?
How Useful is Variable Rate Nitrogen
Dr. Amir Sadeghpour and research collaborators at SIU and UK are developing regionally-specific algorithms fro Illinois farmers to use GreenSeeker sensor tools.
