Title
INJURIOUS EFFECTS OF FERTILIZERS APPLIED WITH THE SEED ON THE EMERGENCE OF FLAX
E. S. Molberg Canadian Journal of Soil Science 1961. doi:10.4141/cjss61-006
Other claims from this paper (11)
- Intervention effect Broadcast nitrogen at 80 pounds caused no reduction in flax stand.
- Intervention effect Broadcast nitrogen at 80 pounds increased flax yield.
- Association Flax yields decreased whenever fertilizer reduced stand to 43 plants per row foot or less.
- Observation The threshold flax stand corresponded to approximately 36 pounds seed per acre.
- Intervention effect Up to 15 pounds nitrogen with flax seed was generally safe in greenhouse tests with adequate soil moisture.
- Intervention effect Mono-ammonium phosphate could safely provide 5 to 20 pounds P2O5 depending on fertilizer analysis.
- Association Increasing fertilizer nitrogen reduced the amount of P2O5 that could be used with flax.
- Intervention effect Mono-calcium phosphate results were more erratic and less satisfactory than mono-ammonium phosphate.
- Intervention effect Mono-calcium phosphate was unsafe above 15 pounds P2O5 per acre for flax.
- Association Commercial fertilizer damaged flax more under low soil moisture.
- Recommendation The authors recommend avoiding normal fertilizer rates in close contact with flax seed unless moisture is adequate.
