The Results of a UF/IFAS Study on Controlled-Release Fertilizer


Nutrition is a major force in the fight to combat the citrus production losses caused by citrus greening. A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) horticulturist, Tripti Vashisth, shares the results of a recent study that indicates that citrus yield and fruit quality can be improved with constant nutrition supplied by controlled-release fertilizer, according to a Citrus Industry article.

Results of the Study

Vashisth maintains that the study saw the most improvement in fruit quality with manganese and boron. “We are seeing improvement when we are increasing the rate of manganese and boron about 20 to 50 percent from what the IFAS recommendation was,” she stated in the article.

Growers are looking for any treatment or option that can help their citrus trees to produce in the face of citrus greening. The disease has severely affected citrus production, with both yields and the trees suffering. Vashisth shared the results of the study at the Citrus Expo in August and other similar meetings in the fall of 2018.
