The flow of carbon from plants to soils is one of the least understood processes in forests. Soils contain a large amount of carbon, and as a consequence, small-scale losses and gains within this pool can have tremendous impacts at ecosystem scales. We focus on carbon dynamics in rhizospheres, the region around roots and their symbionts. That is, we investigate the loss of carbon from roots and its interaction with soil fungi.
