Nitrous oxide incentives required

During the 2020 Soils and Crops workshop in Saskatoon last winter, Richard Farrell of the University of Saskatchewan’s College of Agriculture and Bioresources presented a study on slow and controlled released nitrogen products on the Prairies.

Researchers from the University of Manitoba, Agriculture Canada and the University of Alberta also worked on the study that showed nitrous oxide emissions from Canadian crop production can be significantly reduced with the use of advanced efficiency fertilizers.

However, despite clear environmental benefits of using advanced efficiency products Farrell said researchers were unable to detect any significant agronomic benefits, and that farmers will likely need a financial incentive to increase their use of advanced efficiency fertilizer products.

Nitrous oxide emissions have an atmospheric lifetime of more than 100 years and almost 300 times the global warming potential compared to carbon.
