Plants-microbes-minerals: interactions that drive soil organic matter cycling

Session ID#: 83003

Session Description:
Plants, microbes, and minerals are central to soil organic matter cycling, but the interactions among them are poorly understood. While most plant carbon is decomposed to carbon dioxide, the remainder typically undergoes multiple microbial transformations before it forms longer-term associations with soil minerals. However, the mechanisms by which different plant inputs (i.e. root detritus, rhizodeposition, aboveground detritus) affect microbial utilization of organic materials and subsequent mineral stabilization processes are not well known.

We welcome lab, field, modeling, or data-synthesis studies that investigate plant-soil interactions and organic matter cycling on any spatio-temporal scale. Studies addressing mechanisms of plant inputs to soil organic matter, controls on input rates, as well as consequences for local, regional or global variation in soil organic matter stocks are especially welcome.
