Technical Abstract: Endophyte infection of tall fescue has been shown to enhance soil organic carbon accumulation. However, the mechanisms for how this might occur have yet to be determined. We conducted controlled short-term incubations of tall fescue with and without endophyte infection to detect changes in decomposition of leaf tissue, fate of alkaloids during decomposition, water-stable aggregation, soil microbial biomass carbon, and microbial community structure. Relationships among soil physical, chemical, and biological properties as a function of endophyte infection will be discussed to describe the short-term impact of endophyte infection on the processes of decomposition, transformation, and stabilization of soil organic carbon and nitrogen.
