Foliar Feeding has Merit?

There are reports of macronutrients and micronutrients being foliar applied to give struggling canola plants a boost and potentially hasten or even crop maturity. Canola Council of Canada agronomists are not aware of any scientific research to date here in western Canada that supports the economics of this practice. If growers do choose to try a foliar application, leave a checkstrip or two so an evaluation of the final yields can be made. Council agronomists would like to follow fields with this treatment to harvest and use yield measurements to determine if the application was economical. If you are interested in having a Council agronomist help in evaluation, please contact your local regional agronomy specialist listed at the end of this report.
