Final Report: March 2019
Summary: Increasing from size in western Canada has led many farmers to move back to less efficient broadcast nitrogen application in an effort to hasten spring seeding operations. However, surface application of nitrogen (N) fertilizer can increase the potential for volatilization losses, which reduces the nitrogen use efficiency of the crop. Researchers conducted field experiments to identify fertilizer management practices that reduce the potentials for volatilization losses, and improve fertilizer nitrogen use efficiency for canola. Overall the study findings support the use of in-soil banding of N fertilizers during seeding or near to the time of seeding as a best management practice to enhance nitrogen use efficiency in canola and other crop production systems.
