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 [...]
Can You Get a Hold of Your Soybean Mold with a Threshold?
Recently, I was asked, “How do I know if I should have sprayed a fungicide on my soybeans or not?” Below is a checklist of how to make these decisions and some photographs of a few foliar diseases. Check the weather and scout often. To know if a fungal disease is present, you’ve got to go to the field and look throughout the canopy. If it is warm, wet and humid, you probably have some disease present. There will be a lower fungicide yield response in a dry year, like 2012. Use a forecasting tool. If you are seeing gray [...]
