Rethinking nitrogen efficiency
Tracking nitrogen with stable isotopes offers surprising insights into fertilizer uptake, loss, and management strategies
The winter freeze-up slows but doesn’t stop nitrogen losses
New research shows there are nitrogen transformations ongoing through the winter even with late applications
Glacier FarmMedia – There’s a common assumption that when winter grips the Prairies, there’s no activity in the soil. As a result, urea or ammonium-based fertilizers applied in late fall aren’t thought to emit nitrogen during winter. Reynald Lemke, a research scientist with Agriculture and Agri-Food Canada, flipped this idea on its head this year, […] Read more
