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.
The Illinois Soybean Association (ISA) checkoff and membership programs represent more than 43,000 soybean farmers in Illinois. The checkoff funds market development and utilization efforts while the membership program supports the government relations interests of Illinois soybean farmers at the local, state, and national level, through the Illinois Soybean Growers (ISG). ISA upholds the interests of Illinois soybean producers through promotion, advocacy, and education with the vision of becoming a market leader in sustainable soybean production and profitability.
