Controlled-release fertilizer programs differentially affect leaf nutrition and nutrient factor productivity in mature HLB-affected ‘Valencia’ sweet orange trees in Florida
Huanglongbing (HLB) compromises citrus root function, nutrient uptake, and productivity, making fertilizer management critical for sustaining tree performance in affected groves. This study evaluated conventional and controlled-release fertilizer (CRF) programs in mature HLB-affected ‘Valencia’ sweet orange trees grown...
