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.
9706. Nyborg, M.. 1961. The effect of fertilizers on emergence of cereal grains, flax and rape.. Can. J. Soil Science 41:89-98..
Ammonium nitrate, ammonium phosphate and treble superphosphate fertilizers placed in a band with seeds of wheat, oats, flax and rape were found to delay and/or reduce emergence. Order of tolerance of these crops was oats>barely>wheat>rape>flax. The nitrogen ferilizer was more injurious than the two phosphate fertilizers, when applied on the basis of N and P2O5 content respectively. Injury to emergence increased with lower soil temperature. Damage to flax was apparently increased by soil micro-organisms. Injury to emergence was eliminated when fertilizers were broadcast or placed in a band one inch or more away from the seed.
