Natural Sciences and Engineering Research Council of Canada Industrial Research Chair in 4R Nutrient Stewardship
Dr. Mario Tenuta is advancing 4R nutrient stewardship, an innovative approach developed with the fertilizer industry, to apply the ‘Right fertilizer at the Right rate, at the Right time and in the Right place,’ to enhance production goals, farm profitability and environmental sustainability. Dr. Tenuta seeks to resolve how 4R farming practices reduce emissions of the most important greenhouse gas emitted from soil, nitrous oxide (N2O), as well as developing new practices and the training of students to improve the sustainability of farming systems in Canada. His research will specifically work to evaluate how nitrification inhibitors stabilize fertilizers and reduce N2O emissions and N losses.
