Assistant Professor

Specialty: Agronomy  

Active Projects:

  • Sugarcane cultivar development program: Evaluation of sugarcane (Saccharum spp.) clones at stage III of Florida sugarcane cultivar development program in collaboration with USDA-ARS, Canal Point and Florida Sugarcane League. Cultivars developed by this program (CP cultivars) are cultivated on >90% of Florida sugarcane area and also grown as major cultivars in many Central American countries.
  • Energy cane cultivar development program: Evaluation of energy cane (Saccharum spp.) clones in energy cane breeding program in collaboration with USDA-ARS, Canal Point and BP. Energy cane is a high biomass, low sucrose crop, which can be potentially used for cellulosic ethanol production. 
  • Green cane harvest: Evaluation of the effect of green cane vs. burnt cane harvest on microclimate, soil nutrition, sugarcane growth and yield parameters in Florida. Development and evaluation of techniques to manage sugarcane harvest residue (sugarcane trash) and to determine its long-term effect on soil carbon flux and soil organic matter.
  • Precision Agriculture: Apparent soil Electrical Conductivity (ECa) is an indirect measurement of soil EC, which can be measured quickly with Electromagnetic Induction equipment (EM-38). Soil mapping based on ECa is a very important precision agriculture tool for precise management of soil inputs. I am working to determine the relationship of ECa (measured with EM-38) with soil depth, soil moisture, CEC, soil pH, and available soil nutrients in organic and mineral soils of south Florida. Uses of soil ECa maps include guided soil sampling, assigning variable rates of nutrients, improving the irrigation efficiency, salinity diagnosis, planning drainage remediation, and improving the placement of on-farm tests. 
  • Soil sustainability: An organic soil in southern Florida contains very high (>85%) organic matter. To reduce its oxidation and to improve soil sustainability, I am working on evaluation of no-tillage and minimum tillage practices in sugarcane cultivation. Other different soil sustainability practices, including cover crops and crop rotation, are also under evaluation.
