Michael Essington, Professor Biosystems Engineering & Soil Science Annual Performance Period: January 1, 2006 to December 31, 2006 A. SUMMARY AND IMPACTS. 1. Summary. Provide an overall summary (500 words or less) of your accomplishments during the reporting period. Research concluded to elucidate the chemistry of 2-ketogluconate (KG), a microbial byproduct of glucose (a root exudate and monosaccharide) oxidation, and to enhance our ability to predict the fate and behavior of substances in soil systems. The multivariate statistic analysis of spatially-indexed soil chemical data illustrate that landscape position and soil drainage characteristics are reflected in the chemical data. Although such a finding is expected, the observation that only minor changes in topographical characteristics (e.g., elevation) strongly impacts the chemical characteristics of west Tennessee loess-derived soils was unexpected. Conducted research to test the hypothesis that the source of stream sediments could be identified using mult-elemental analysis and multivariate statistical techniques. Preliminary findings indicate that the technique has considerable promise. 2. Impacts. List up to three significant impacts of your program. Impact statements should be one to three sentences and should be written in a way that would be meaningful to the public. The textbook, ‘Soil and Water Chemistry: An Integrative Approach,’ (M.E. Essington, 2003, CRC Press) is currently being employed at numerous national and international universities in soil chemistry and environmental soil chemistry courses. More than 1600 copies of the text have been sold, and the book is now in its second printing and modifications for a second edition are in progress. The book is now listed as a 'best seller' according to CRC Press. 2-Ketogluconate (KG) is a microbially-produced low-molecular-mass organic acid the may be found in soil at significant concentrations, particularly in manure-amended soil and in soils that contain low bioavailable phosphorus levels. Our research indicates that this microbial exudate may play an important role in the cycling of nutrients (Fe and P) and in the detoxification of trace elements (Al) in the soil environment. The results also indicate that soil biota have several chemical tools at thier disposal (in addition to citrate, oxalate, etc.) that are capable of enhancing nutrient availability and metal behavior in soil. Through the multielemental analysis of watershed surface soils and stream sediments, we were able to show that stream sediments could be traced to source. This is a major finding that could potentially revolutionize current practices for evaluating the impacts of land management on non-point source pollution. The method is analytically simplistic and statistically valid. B. PROJECTS AND PROGRAMS (EXTENSION, RESEARCH AND TEACHING).
