Nutrient Stewardship


Canadians understand the importance of sustainable environmental solutions. 4R Nutrient Stewardship (Right Source @ the Right Rate, Right Time, and Right Place®) was developed to help crop-producers minimize environmental concerns related to agriculture while maximizing economic benefits.

4R Nutrient Stewardship has been promoted and applied across Canada under Agriculture and Agri-Food Canada’s Agricultural Greenhouse Gases Program and the AgriInnovation Program (Growing Forward 2). A number of environmental concerns related to agriculture are evident across Canada, including: excessive phosphorous loadings, nitrate levels in drinking water, soil conservation, salinity, and soil and air quality concerns. 4R Nutrient Stewardship research provides crop producers with science-based information and advice on how to use best management practices to reduce emissions of greenhouse gases and address other environmental impacts when they apply fertilizer.
