Given the complexity of edaphic systems - root structure, function, and rhizosphere interactions are understudied components of horticultural sciences. This is even more important in Florida, where many soils possess significant challenges to achieving sustainable and effective fruit production due to low natural fertility and organic matter. In addition to challenging soil conditions, maintaining proper nutrition for citrus is further exacerbated by citrus greening (huanglongbing, HLB), which damages the root system first. There is no cure for HLB, and no commercial varieties or scion-rootstock combinations are resistant to the disease. Maintaining a healthy root system is vital for keeping the Florida horticulture industry productive and profitable. The goal of our laboratory is to increase yield and quality of horticultural crop commodities by developing sustainable, environmentally sound, and effective management practices that improve and restore plant, root, and rhizosphere health.
