We have been involved in several collaborative research projects conducted in agricultural systems. I am thrilled to be returning to work with Dr. E. Pattey at Agriculture and Agri-Food Canada (AAFC) in summer 2022 around greenhouse gas emissions from cropped systems. Stay tuned for more details...!
We have collaborated with Dr. Asim Biswas at the University of Guelph in evaluating a new soil water sensor capable of measurement at field scale. This project formed the PhD research of Dr. Duminda Vidana Gamage.
We completed a project with (AAFC) Ste. Foy, led by Dr. Philippe Rochette. With Dr. Andy VanderZaag of AAFC, Ottawa, we evaluated the ammonia volatilization using wind tunnels. Devon Watt completed Master's level research within this project.
