Other claims from this paper (6)
- Observation Zn concentration in the 0–15 cm soil depth was three times higher than in the 30–45 and 45–60 cm depths.
- Observation Zn sorption coefficients were high (KD = 6.5) at 0–15 cm soil depth.
- Observation The 30–45 and 45–60 cm depths showed little Zn sorption.
- Intervention effect Leaf Zn concentration for foliar spray was two times higher than for the soil application method.
- Recommendation Foliar Zn at 5.6 or 11.2 kg ha−1 and N at 224 kg ha−1 appear adequate for improving the performance of HLB-affected citrus trees.
- Intervention effect A nitrogen level of 224 kg N ha−1 improved canopy volume compared with other N levels.
