Nitrogen loss: Lessons learned from the 2024 growing season

Abstract

Nitrogen loss: Lessons learned from the 2024 growing season is the big topic on today's episode of the Nutrient Management Podcast. What N application practices looked particularly bad in 2024? Some farmers are saying they are no longer going to apply fall N based on how 2024 played out. Is this warranted, or is it an overreaction? Is there any data back from split-application trials, or evaluations of rescue treatments? What did it tell us? In hindsight, what would have been ideal practices to have used this past year? Moving forward, what can we take away from the 2024 growing season with respect to how to manage fertilizer?
