Current Research Project:
BEHAVIOR OF SELECTED SURFACTANTS IN SOIL: INTERACTIONS WITH PHYSICOCHEMICAL AND MICROBIAL PROPERTIES.
The objectives of this project are:
1. Study the changes in soil microbial consortia as affected by different surfactants.
Knowledge of the natural evolution of microorganisms in the soil will be crucial to successful study of the fate of these chemicals and possible bioremediation design schemes.
2. Determine the effect of different surfactants on plant nutrient uptake.
This objective will investigate the possible interactions of surfactants with macro-and micronutrient uptake by plants.
3. Measure the activities of enzymes involved in the cycling of C, N, P and S in the presence of different surfactants.
Surfactants can interact with microbial enzyme activity, stability and/or specificity to positively or negatively affecting their role in nutrient cycling and fertility in the soil environment.
4. Determine the impacts of soil physicochemical properties (e.g, pH, CEC, free Fe and Al- oxides, organic C, particle size distribution) on sorption of surfactants in soils.
The most effective method of application of surfactants to soil would depend, in part, upon the adsorption isotherms of the surfactant by the soil.
