soil C cycling


Molecular interactions of the plant-soil-microbe continuum of bioenergy ecosystems

This research aims to reveal the microbial mechanisms that regulate carbon (C) stabilization in soils dedicated to biofuel crops, and test identified mechanisms in ecosystem-scale field experiments. Emerging evidence suggests that dead microbial biomass, or necromass, constitutes a significant fraction of soil organic matter. Although microbial necromass stabilization is frequently invoked as a mechanisms for long-term soil C storage, there remains limited empirical data illustrating the complement of molecules that comprise microbially derived soil organic C.
