SUMMARY OF RESEARCH DIRECTIONS

Dr. David E. Kissel is administrative head and Director of the Agricultural and Environmental Services Laboratories (AESL) of the University of Georgia. This unit provides testing services for farmers, researchers, homeowners, and industry clients. The three faculty in this unit also carry out applied research in the development of new laboratory testing protocols and they collaborate with other faculty in the College on research and outreach projects that depend on the AESL testing protocols.

Dr. Kissel is author or co-author of over 100 refereed scientific articles and numerous popular scientific articles on nitrogen and phosphorus fertilizer use and cycling in soils and crops. Recent research has been in the areas of mapping of soil properties such as organic carbon and clay across field landscapes using remote sensing and GIS technologies. Research is in progress on new laboratory methods, including the development of better methods for routine determination of soil pH and lime requirement. Dr. Kissel has an extensive background on sorption of ammonia by soils and the reaction of urea in soils. Some of his present research involves the study of ammonia sorption by chars, a product from biofuels production.
