Improved N application methods and N sources for corn in Southwestern Ontario

IPNI-2014-CAN-4RC02

Introduction: Increased farm sizes have resulted in greater time constraints for producers to apply nitrogen fertilizers to crops. Hence, some producers have now started applying their N by either streaming UAN onto their soils or are considering adding inhibitors with urea or UAN to reduce losses of applied N. Read more

Interpretive Summary

Corn producers often apply nitrogen (N) fertilizer by either streaming urea-ammonium nitrate (UAN) or broadcasting urea onto the soil. They are considering adding inhibitors to reduce losses of applied N. Compared to other N sources, urea and UAN fertilizers have higher risks of ammonia loss. As with other N sources, denitrification and nitrous oxide (N2O) losses can also be substantial.
