The sandy soils in south Florida - including those of the Indian River region - suffer from low organic matter content, which limits water-holding capacity and retention of nutrients. Coupled with typically elevated temperatures during summer months, organic matter from crop residues and amendments becomes rapidly decomposed, which further decreases soil quality.
Irrigation with saline groundwater has initiated high pH conditions in some surface soils, which further stress crops. Intensive water, fertilizer, and soil management of these marginal areas is necessary to optimize crop production.
Dr. Wright's research and Extension program focuses on identifying management strategies that can improve soil quality, while minimizing adverse environmental effects.
