Factsheet: Optimizing Nitrogen Fertilizer Management Strategies for High-Yielding Spring Wheat in Manitoba
Current provincial N fertilizer guidelines are outdated and were developed with lower yielding varieties than currently being grown today. The current recommendation of 2-3 lbs N/bu yield potential creates large financial, environmental, and agronomic risks if applied using traditional methods. When high yields are achieved, protein content is at risk of being inadequate for milling purposes. Mid-season N fertilizer application may mitigate that risk, but minimal research has been done under MB growing conditions.
