Split nitrogen application: Manitoba farm puts timing to the test
Hartney-area farmers experiment with spreading nitrogen across multiple passes, matching fertilizer timing to crop demand
VIDEO: THROWBACK: Targeting your fertilizer needs using the 4Rs
Synchronizing nutrient uptake and 4R principles for optimal crop results
Marla Riekman with Manitoba Agriculture talks about the 4Rs and the effective use of fertilizers when growing crops.
Canola sees no yield drop in seed-placed phosphorus trial
Phosphorus fertilizer put down with seed limits plant stands, not yield, Saskatchewan research shows
Saskatchewan trials show seed-placed phosphorus in canola rarely reduces yield but often reduces plant stands, shifting risk to crop establishment.
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.
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

Fall soil testing tips for smart fertilizer plans
Quality 2026 crops start with quality soil test data, which starts with Manitoba farmers using the best possible soil sampling practices in fall 2025
Quality crops next year start with quality soil test data, which starts with Manitoba farmers using the best possible soil sampling practices in fall 2025
Precision 4R cuts farm greenhouse gas emissions
Lower areas in your field tend to emit more greenhouse gas, research shows that precision 4R nutrient stewardship practices can help mute the trend

Biogas pitched to turn farm waste into renewable energy
Anaerobic digestion can convert manure and other agricultural waste into renewable energy as well as fertilizer, but Manitoba farmers don’t have the best history with the technology
