Speaker: Christopher Kucharik

Agriculture’s long-term reliance on nitrogen to maintain or increase crop productivity over the last several decades has contributed to increased nitrate concentrations in groundwater across Wisconsin. Climate change will bring a shift towards increased precipitation and a higher frequency of extreme rainfall events that will make nutrient management more challenging thereby exacerbating current water quality issues. This presentation will review our current understanding of the intersection of nitrogen, groundwater quality, and climate, highlight ongoing field research, and present numerical modeling results and new decision support tools that could help us on our quest to reduce nitrogen losses to groundwater from agricultural land management in a changing climate.
