Nitrogen placement: What Minnesota farmers should know about depth, incorporation, loss pathways, and more

Understanding how nitrogen behaves in the environment is more important than ever. And when growers have access to unbiased, research-based information, they’re better equipped to make farm-specific nitrogen management decisions. Here at Advancing Nitrogen Smart, we unpack and examine the latest up-to-date nitrogen data to help farmers maximize their profits while at the same time minimize nitrogen loss to the environment. We cover topics that are timely and relevant for Minnesota farmers and agricultural professionals, just as we’ve been doing for the last 10 years with our in-person and online Nitrogen Smart courses. We’re starting off this series with a discussion about placement, and what Minnesota farmers should know about depth, incorporation, loss pathways, and more!
