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.
