Other claims from this paper (9)
- Intervention effect AS+DMPP increased orange tree biomass.
- Intervention effect AS+DMPP produced a more profuse root system.
- Intervention effect AS+DMPP raised fruit yield.
- Intervention effect DMPP addition significantly increased fertilizer 15N uptake.
- Intervention effect AS+DMPP soils had lower -N concentrations from April to June.
- Intervention effect DMPP reduced fertilizer 15N loss in drainage to less than 3%, versus 9-10% with CPN or AS.
- Intervention effect AS+DMPP gave the highest nitrogen uptake efficiency, 69%, versus 61% for CPN and 54% for AS.
- Observation High summer temperatures significantly reduced DMPP activity.
- Recommendation The authors recommend DMPP supply during spring fertilization.
