Post-Emergent Nitrogen Applications Have Potential for Increasing N-use
Efficiency in Spring Grains
Drs. G. Lafond, S. Brandt, W. May, C. Holzapfel and A. Johnston
Provisos are that some starter N is applied at time of seeding, but the
amount of starter N is dependent on how much risk the grower is willing to
assume by going with more N after crop emergence.

Applying Some Starter N at Seeding Critical in
Spring Wheat and Canola
Drs. G. Lafond, S. Brandt, W. May, C. Grant and A. Johnston

applied at seeding to minimize risks with post-emergent N applications.
