Although phosphate fertilizers are commonly applied either by surface broadcasting or banding with the seed to dryland spring wheat, data are limited on the residual effects of previous fertilization on plant growth and drought periods during the growing season. Therefore, the residual effects of P fertilization on spring wheat grown on Parshall fine sandy loam were determined in a field study at Mandan, North Dakota.
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.
