Soil fertility & nutrient management; efficient use of fertilizers; soil enzymology; pesticide biodegradation.

Frieda Eivazi is Professor of Soil and Environmental; she has adjunct appointment at University of Missouri-Columbia (UMC). Her present research is on development of the bioremediation techniques to be applied to point-source contamination of widely used pesticides for crop production.  Dr. Eivazi has been the PD or Co-PD of many research projects funded by different agencies and has numerous peer reviewed publications including two book chapters. Eivazi has served in national review boards or panels for NSF, EPA, and USDAand is member of editorial review board for the Journal of Plant Nutrition, and Communications in Soil and Plant Analysis, and Journal of Soil Ecology.
Current Research Project:
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.
