Research Interests (with focus on Tropical Agriculture)

My research program focuses on the elucidation of nutrient cycling in calcareous soils, development of management practices to improve nutrient use efficiency, crop production, and water quality, and the impact of agriculture on south Florida’s natural ecosystems. My specific research areas include: a) understanding chemistry N, P, S and other nutrients in high pH soils; b) developing BMPs to improve fertilizer use efficiency; b) evaluating cover crops for improving soil quality; c) Conducting experiments on soil amendments; and d) Improving water quality monitoring and chemical analysis.

Teaching Interests (with focus on Tropical Agriculture)

My official assignment includes research and extension but not teaching.  Nevertheless, I am very actively involved in advising and mentoring undergraduate interns, graduate students, and postdoctoral research associates. I regard my teaching and mentoring activity as a great privilege and an important responsibility. It affords me the opportunity to work with very bright and talented young people who will hold important positions in future years.

Extension/Outreach Interests (with focus on Tropical Agriculture)

My extension program includes 1) implementing fertilizer BMPs; 2) increasing uses of cover crops and soil organic amendments; and 3) educating clienteles on water quality concepts and technology of monitoring and analysis.
