Nitrogen fertilizer production and use is responsible for about 30 percent of Canadian agricultural GHG emissions. Rising nitrogen fertilizer tonnage is the main reason agricultural emissions are increasing. Nitrogen fertilizer is probably unique among all human materials and processes in that it is a major source of all three main GHGs: nitrous oxide, in use; carbon dioxide, in its production; and methane, from its natural gas feedstock.
Though rising N use creates an emissions challenge, there are many farm-level changes that can help farmers use less fertilizer while still maintaining yields. Dr. Mario Tenuta will outline many of these promising approaches, discussing nitrogen efficiency, placement, timing, and formulations and coatings. To reduce agricultural emissions we must reduce emissions from nitrogen. Dr. Tenuta will show us some of the ways that might be possible.

Speaker
Dr. Mario Tenuta is a professor in the Department of Soil Sciences and heads the Applied Soil Ecology Lab. From 2006 to 2017 he served as the Canada Research Chair in Applied Soil Ecology. Dr. Tenuta is one of Canada’s foremost experts in nitrogen use and ways to reduce use and emissions. In his outreach to farmers and others, he works to translate discoveries to recommendations and advice for growers, crop consultants, retailers, and industry.
