Representing the Soil, Water and Nutrient management Laboratory were five presenters:
Kelly Mahan-Percivall, who is a Master’s student researching the topic of Alginate/Glomalin Biobeads: An initial determination of Structural Cohesivity, Nutrient Remediation Ability and Reapplication Viability. Preliminary results from Kelly’s work suggests that the quick initial absorbance of orthophosphate by the 45/5% group suggests that there is a glomalin driven absorption factor which may achieve the desired reduction in the characteristic leaching of nutrients.
Nan Xu is a Ph.D. student, presented her research titled Application of Bagasse for Sugarcane Production on Sandy Soils in South Florida. Nan’s experiment is being conducted on commercial sugarcane production fields, where three bagasse application treatments with different rates, 2-inch bagasse, 4-inch bagasse, 4-inch bagasse plus split nitrogen application is being compared to one control with no bagasse application. Several soil properties including soil pH, bulk density, maximum water holding capacity, organic matter content, cation exchange capacity, active carbon, and nutrient content (specifically, nitrogen, phosphorus and potassium) are being evaluated before and after the bagasse application to quantify its effects on sandy soils. As she continues to monitor changes in soil quality, for the next three years, preliminary results look promising.
