Iowa Learning Farms Webinar: Quantifying and Managing Residual Soil Nitrogen
February 22 @ 12:00 pm - 1:00 pm
The Iowa Learning Farms (ILF) conservation webinar taking place Feb. 22 at noon CST will feature Greg LaBarge, field specialist, agronomic systems department, The Ohio State University. LaBarge conducts research and outreach on nutrient management and water quality issues through The Ohio State University Extension. His work focuses on the application of 4R (Right Source, Right Time, Right Rate, Right Place) management of nitrogen (N), phosphorus (P) and potassium (K) in row crops, and conservation practices which help limit downstream impacts of nutrients leaving farm fields.
Iowa Learning Farms is an Iowa State University Extension and Outreach conservation and water quality education program.
In the webinar, “Quantifying and Managing Residual Soil N after Corn,” LaBarge will highlight research conducted to help measure residual nitrogen in soil after harvest and discuss management techniques such as cover crops which have proven to limit transport of nutrients to waterways. He will also discuss edge of field losses and additional conservation practices that mitigate nutrient losses.
“Having sufficient nitrogen (N) is critical to supporting maximized crop yields, but our studies are showing a significant amount of residual N in the soil after harvest,” said LaBarge. “Research has shown that the use of cover crops after corn is an effective way to capture residual N as organic matter and improve soils. Identifying and encouraging the deployment of additional practices which keep that N in the field is important to achieving both long-term economic and environmental goals.”
Participants are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
