Exploring Impacts of Cover Crops, Tillage, and N-Inhibitors on Crop Performance and Water Quality

Thursday, November 5, 2020 - 1:00pm

Iowa Learning Farms, in partnership with the Iowa Nutrient Research Center, and Conservation Learning Group (CLG), is hosting a free virtual field day exploring impacts of cover crops, tillage and nitrogen-inhibitors on crop performance and water quality on Thursday, November 5th at 1 p.m. CST. Join us for a live conversation with Matt Helmers, Director of the Iowa Nutrient Research Center, Emily Waring, Graduate Research Assistant, and Carl Pederson, Agricultural Specialist in Agricultural and Biosystems Engineering at Iowa State University.

Since 1989, research focused on the effects of nitrogen (N) management on crop production and tile drainage water quality has been conducted in north-central Iowa near Gilmore City. In 2010, the treatments were changed to examine the impacts of cereal rye winter cover crop vs. no rye (with and without tillage), conventional tillage vs. no-till, and timing of N-application and use of nitrification inhibitor. Through extensive data collection and monitoring the team is measuring the impact of these practices on nitrogen and phosphorus loss and crop yield.

“This long-term dataset allows us to examine the impacts of conservation practices under a range of weather conditions. We have measured cover crops as an effective practice in reducing N loss from the cropping system,” says Helmers.
