When its dry, doesn it make sense to only use minimal nitrogen (N) fertilizer with canola and cereals and then broadcast more N when moisture conditions improve?
Delaying N fertilization until after seeding will work in some situations, but the window of opportunity to make it successful is narrow and the decision about adding additional N must be made within a few weeks of seeding. Since topdressed N is inefficient, and usually requires a custom floating operation, the total costs of broadcasting after seeding are considerably higher than if a comparable amount of N would have been applied at seeding.
