Resumen

In this article we provided updates on research efforts to improve the nutrition of HLB-affected Florida citrus by revising the diagnostic critical threshold concentrations of nutrients in leaf tissue. We also revisited the DRIS method for improving diagnosis of multiple nutrient deficiencies that are common in HLB-affected groves, including K, Mg, Mn, Zn, Fe, B, and Cu. Additional leaf nutrient data will be obtained for an expanded survey, to be analyzed and corroborated with results of recently completed micronutrient fertilization experiments.
