Verbatim
e1“Emergence of flax and rapeseed was often reduced to less than half by row placement of 33.5–0–0 at a rate of 17 kg N per ha, or by 11–48–0 at rates of 15 to 20 kg P per ha, and yields were usually greater when damage to emergence was avoided by placing the fertilizers away from the row”
e3“Fields tests were conducted with commercial fertilizers applied to barley, flax and rapeseed by placement in the row and by placement in different positions away from the row”

Other claims from this paper (10)
- Intervention effect Row placement of 33.5–0–0 at 34 kg N per ha delayed barley emergence.
- Intervention effect Row placement of 33.5–0–0 at 34 kg N per ha did not substantially reduce barley emergence.
- Intervention effect Row placement of 0–45–0 at rates up to 39 kg P per ha did not substantially reduce barley emergence.
- Intervention effect Row placement of 11–48–0 at rates up to 39 kg P per ha did not substantially reduce barley emergence.
- Intervention effect Row placement of 33.5–0–0 at 17 kg N per ha reduced flax and rapeseed emergence to less than half.
- Intervention effect Row placement of 11–48–0 at 15 to 20 kg P per ha reduced flax and rapeseed emergence to less than half.
- Intervention effect Yields were no greater for barley, flax and rapeseed when fertilizers were placed away from the row.
- Intervention effect When higher fertilizer rates were used, placement away from the row gave much greater yields than placement in the row.
- Observation Phosphorus fertilizer efficiency varied considerably with the position in which it was placed.
- Observation A position 2.5 cm directly below the row was the best phosphorus placement for barley and flax.
