Dr. Gabriel Maltais-Landry is an assistant professor of sustainable nutrient management systems in the UF/IFAS soil and water sciences department (SWS). He said the different nitrogen rates did not affect leaf nitrogen and soil extractable concentrations. Similarly, the application of calcium did not increase soil calcium extractable concentration relative to the grower standard. It did have a slight effect on leaf calcium, however.
“In contrast, magnesium was effective at increasing both leaf and soil magnesium concentrations,” he said. “Overall, our results suggest a greater impact of magnesium fertilization on soil and nutrient concentrations than nitrogen or calcium fertilization.”
Dr. Davie Kadyampakeni is an assistant professor of citrus water and nutrient management at the UF/IFAS Citrus Research and Education Center and co-author of the research article. He said future studies with a larger sample size and longer duration could help determine the strength of these interactions and their long-term implications. Additionally, measuring nutrient losses through leaching in the future would provide a more thorough understanding of the fate of these nutrient inputs.
“Overall, this study provides insights on the bene?ts of a balanced nutrition approach to ensure the optimal growth of HLB-affected citrus trees in Florida,” he added.
