Virtual Field Day: Manure Application and Cover Crop Planting Timing to Maximize Water Quality Benefits in Corn

Event Type: 

Iowa Learning Farms and the Iowa Nutrient Research Center will host a virtual field day on Thursday, March 12, at 1 p.m. Central time. The free event will feature a live discussion with Dan Andersen, associate professor and extension agriculture engineering specialist at Iowa State University, Raj Raman, Morrill Professor of agricultural and biosystems engineering and Philip Rockson, agricultural and biosystems engineering graduate research assistant at Iowa State.

The virtual field day aims to provide valuable insights into the impacts of different cover crop systems and manure application methods on water quality and corn yield. In this innovative project, funded in part by the Iowa Nutrient Research Center, the focus is on how timing affects yield and water quality when comparing fall and spring manure applications.

“We've done a fair amount of work on the timing of manure application, looking at late fall manure versus early fall manure impacts on corn yield and water quality, knowing that some people are stressed about ‘when can we get manure on in the fall,’” noted Andersen. “We saw huge timing responses, and one of the next questions was ‘How much different is it when you move manure application to spring?’”

Participants are also encouraged to ask questions.
