Title

P. Qian; J. J. Schoenau Journal of Plant Nutrition 2000. doi:10.1080/01904160009382024
Other claims from this paper (6)
- Intervention effect Swine manure increased canola phosphorus accumulation.
- Intervention effect Urea increased canola phosphorus accumulation.
- Intervention effect Manure and urea raised the proportion of phosphorus in canola seeds, more evidently with manure.
- Intervention effect Manure significantly increased soil nitrogen and phosphorus supply rates in canola pots.
- Intervention effect Urea significantly increased soil nitrogen supply rate.
- Mechanism Despite lower available soil phosphorus supply under urea, canola maintained its nitrogen-to-phosphorus ratio by absorbing more phosphorus.
