Leverage NRCS Conservation Practice 336 to Improve Soil Health
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, …
Early Data on Biofertilizer for HLB-Affected Trees
