We have been involved in several collaborative research projects conducted in agricultural systems. Two recently completed projects are:
We completed a project with Agriculture and Agri-Food Canada (AAFC) Ste. Foy, led by Dr. Philippe Rochette. With Dr. Andy VanderZaag of AAFC, Ottawa, we evaluated the ammonia volatilization measured using wind tunnels. Devon Watt completed Master's level research within this project.
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.
