WEBINAR: Nitrogen Management Systems in Tile Drained Fields: Optimizing Yields and Minimizing Losses

Lowell Gentry will demonstrate annual nutrient losses from tile drained agricultural watersheds in east central Illinois and will focus on a replicated tile drainage study under a corn/soybean rotation. Our research group monitors 36 tile lines on one farm which accommodates 6 nitrogen treatments with 3 replicates and both crops. Treatments range from fall nitrogen application to split applications (spring and side-dress) with a cover crop. The major objective of the study is to evaluate the yield response and the tile nitrate losses associated with each of the N management systems. Additionally, this study will determine when and how tile nitrate losses occur in these systems, under both corn and soybean production.
