Strategies for N loss reduction while maintaining crop productivity are crucial in developing sustainable agriculture. Our research has shown that procyanidins can significantly reduce denitrification enzyme activity (DEA) and thus N2O emissions in soils from Minnesota corn fields by 10- 80%,

Mitigating cold and warm season nitrogen losses from corn systems (Year 2)
Assess whether winter rye cover cropping and enhanced efficiency fertilizers (EEFs) can effectively reduce reactive N losses during the spring freeze-thaw period while maintaining high corn yields
Reducing reactive nitrogen loses from corn systems
Over the last several years our regional atmospheric measurements and mesocosm experiments have revealed that reactive nitrogen losses associated with corn production are likely to increase as our climate continues to get warmer and wetter.
How is Climate Change in Minnesota Affecting the Sustainability of Corn Production?
The goal of this project is to develop a state-of-the-art large mesocosm facility to examine how climate change will impact agricultural productivity and other environmental impacts in Minnesota.
Agricultural Production and the Hydrologic Cycle in the Upper Midwest
The aim of this research is to gain a better understanding of how agriculture fits within the regional water cycle in the Upper Midwest. This project will use a combination of measurements made at field and regional scales
