Studies show yield advantage to extra nitrogen on wheat
Once wheat starts to green up it is time for you to apply nitrogen.
For years Ontario research indicated that maximum yield came from about 90-100 pounds per acre of actual nitrogen. Work by Dr David Hooker University of Guelph the past two years and farm plots by the Ontario Soil and Crop Improvement Association under the direction of Peter Johnston, Ontario Ministry of Agriculture, Food and Rural Affairs’ cereals specialist, suggest that there may be an economic advantage to applying more than this.
