Other claims from this paper (9)
- Intervention effect Banded ammonium nitrate, ammonium phosphate and treble superphosphate delayed and/or reduced emergence.
- Observation Oats were the most tolerant and flax the least tolerant of the crops to banded fertilizer.
- Association Injury to emergence increased with lower soil temperature.
- Association Injury to emergence increased with lower soil moisture content.
- Observation For wheat, oats and barley, delay in emergence was more pronounced than reduction.
- Intervention effect For flax and rape, relatively light fertilizer applications both delayed and reduced emergence.
- Intervention effect Exposure of seeds to fertilizer in soils of low moisture content rapidly reduced their ability to germinate.
- Association Soil micro-organisms apparently increased damage to flax from fertilizer.
- Intervention effect Injury to emergence was eliminated when fertilizers were broadcast or placed in a band one inch or more away from the seed.
