At Citrus Expo, University of Florida soil scientist Kelly Morgan said nutrient uptake by HLB-infected trees can be improved by applying the proper amount of nutrition and managing pH. “Those two things go hand-in-hand,” he said. “As you reduce soil pH below 7, you increase the uptake of most nutrients. So we need to reduce our pH. Our pH has …
