Other claims from this paper (10)
- Intervention effect Fruit yield rose linearly and was greater with CN.
- Intervention effect Nitrogen use efficiency fell with increasing N rates for both forms.
- Intervention effect NUE was 14 to 38% greater for CN than AN.
- Association AN was associated with lower fruit yield than CN.
- Association AN was associated with lower NUE than CN.
- Association Increasing AN rates increased soil solution acidification.
- Mechanism Limited nitrification produced high ammonium concentration in soil solution.
- Mechanism Limited nitrification reduced net cation absorption by trees, particularly calcium.
- Recommendation The authors concluded that CN could increase fruit yield in fertigated tropical citrus groves.
- Recommendation The authors concluded that CN could increase NUE in fertigated tropical citrus groves.
