 Employee inspects soil testing equipment

AFSRC scientists are studying the role of plant-based polyphenolic compounds, such as tannins, on Appalachian agroecosystems. An understanding of how tannins and other plant-derived polyphenolic compounds interact with soil and affect the basic fluxes and transformations of soil organic matter and the availability of important plant nutrients such as nitrogen and phosphorus is expected to yield useful information that provides a rational basis for developing management strategies for soil nutrients. Tammy Robertson (Biological Science Technician) is inspecting some of the laboratory equipment used in the analyses of polyphenolic compounds.

Further information about the research can be obtained from Dr. Jonathan Halvorson.
