By Tripti Vashisth, Taylor Livingston and Abhishek Neupane Florida citrus production occurs predominantly on sandy soils that are inherently low in organic matter and possess limited water- and nutrient-holding capacity. These soil constraints have become increasingly important in the era of huanglongbing (HLB), where compromised root systems reduce the tree’s ability to efficiently acquire water and nutrients. As a result, …
