Animals excrete a lot of nitrogen as they grow with a large fraction escaping into the air as ammonia. What happens to that ammonia, and can we predict how that excess nitrogen might be beneficial to nearby crop production? This webinar will present pilot-scale research for manure and food waste treatment. This presentation was originally broadcast on May 16, 2025.

The Role of Agriculture in Atmospheric Nitrogen Deposition: Sources, Impacts, and Management
Agriculture is the largest source of ammonia emissions and contributes to nitrogen deposition which can impact ecosystem health. This webinar introduces the topic of nitrogen deposition and provides an overview of the role of the National Atmospheric Deposition Program (NADP) in determining nitrogen deposition sources. In addition, the speakers provide an overview of a region being impacted by agriculture related nitrogen deposition and discusses agricultural management practices that may reduce ammonia emissions and nitrogen deposition. This presentation was originally broadcast on September 20, 2024. Continue reading “The Role of Agriculture in Atmospheric Nitrogen Deposition: Sources, Impacts, and Management”
