How to succeed at 4R fertilizer management on your farm

Agronomy Management: The “right” approach for on-farm nutrient management and fertilizer varies from region to region in Western Canada

4R nutrient management must be farm-specific — geared for the unique crops, cropping practices, soils and climatic conditions of that farm, researcher Ross McKenzie writes.

Still hard to predict precise fertilizer payback

Despite decades of precision agriculture advances, international research finds no clear way to predict where and when adding nutrient through fertilizer will fail to boost growth

Despite decades of advances, international research finds no clear answer for where and when adding nutrient will fail to boost growth.

Nutrien pays farmers for efficient nitrogen

Nutrien’s Sustainable Nitrogen Outcomes (SNO) program pays Prairie farmers to limit nitrogen loss and, therefore, fertilizer-related greenhouse gas emissions.

How much nitrogen can farmers really cut?

Manitoba fertilizer trials search for the the sweet spot where farmers can cut nitrogen rates, with a nitrification inhibitor, without harm to yield

Manitoba fertilizer trials look for nitrification inhibitor sweet spot, to lower greenhouse gas emissions and cost without hurting yield.

OECD lauds Canada’s low farm subsidies, except supply management

The Organization for Economic Co-operation and Development says Canada’s farm subsidies are among the lowest, but still criticized supply management industries like dairy, poultry and eggs

Fertilizer label changes called costly, unnecessary

Canada’s bulk fertilizer makers now have until July 2026 to update their labels, but industry says the rules will be expensive to implement and won’t actually provide safety gains
