2043. Fowler, D.B. and J. Brydon. 1989. No-till winter wheat production on the Canadian prairies: placement of urea and ammonium nitrate fertilizers.. Agron. J. 81:518-524.
A practical snow management system, which utilizes no-till seeding into standing stubble immediately after harvest, has permitted expansion of winter wheat production in western Canada. This study examined grain responses to urea and ammonium nitrate fertilizer banded and broadcast at seeding, or broadcast in the late fall or early spring. A moisture shortage biased the results. Fall banding prior to seeding helped reduce volatilization losses of urea (which were as much as 50%), but presented other problems and did not outperform broadcast ammonium nitrate.

In this rainfall zone, treatments with 25-50% if the N banded below the seed at planting and the remaining N spring broadcast, produced significantly higher yield and N use efficiencies when compared to the average of all other treatments. At the lower precipitation, more N should be fall-applied than in the wetter areas. Banding avoids some of the weed stimulation caused by broadcast N applications.
