Brief description of research program and goals:
My scholarly program is oriented toward the area of biogeochemistry with primary emphasis on carbon, nitrogen and phosphorus cycling in agricultural and natural ecosystems. More specifically, fluxes of these elements and their impact on the environment owing to anthropogenic activities are being investigated in a basic and an applied manner. A large effort has been put forward in my program to identify and solve soil, water and air contamination problems arising from land-disposal of wastes (manure and dead animals) from animal agriculture in the Southeast. Another area of on-going research in my program is evaluation of new and existing technology for prediction of crop nitrogen needs. This research area has both agronomic and environmental implications, because current nitrogen recommendation strategies are non-site specific. Part of my scholarly program is aimed at development of a fundamental understanding of nutrient cycling processes. I have conducted studies on carbon and nitrogen cycling in several systems including agroecosystems having different tillage management, cover crops and amendments, and loblolly pine stands having different vegetation management. In addition, I have investigated the impact of increasing atmospheric carbon dioxide concentrations on carbon and nitrogen cycling processes. I have also been involved in research designed to elucidate carbon and nitrogen cycles in commercial fish ponds.
Brief description of outreach program and goals:
Although I have no formal extension appointment, I have participated in technology transfer to producers of agricultural and silvicultural commodites in the state of Alabama. I have also participated in “in-service” training for County Agents. I have also been involved in implementing on-farm demonstrations designed to educate producers as to proper agronomic/environmental practices. Moreover, I have made presentations to politicians and leaders of the agricultural community inside and outside Alabama.
