Greater adoption of the 4R Nutrient Stewardship Framework is central to the federal government’s 30 per cent fertilizer emissions reduction target for Canadian agriculture. According to the most recent 4R Nutrient Use Survey, familiarity and uptake have increased, yet barriers to improvement exist. Ongoing research indicates field practices can effectively curb nitrogen emissions. GrainsWest spoke with industry experts who all emphasized the benefits of 4R principles.

While fertilizer is critical to keep farmers in the black, many see red as its cost has greatly increased. As prices are on the upswing, industry groups and researchers turn their attention to new ideas that may boost ROI.

The use of nitrogen fertilizer in agriculture has increased over the years as farmers have sought to boost crop yield. This reliance can bring unintended consequences in the form of nitrous oxide emissions, a greenhouse gas that contributes to ozone depletion. For decades, scientists around the world have worked to remedy this problem.
