Origin and fate of dissolved organic matter in the subsoil

The main objective of this sub-project is to study the complex interactions between organic matter and mineral surfaces during the migration of dissolved organic matter in subsoils by investigating both abiotic and biotic processes as controls of dissolved organic carbon cycling. We particularly focus on interactions between adsorption of dissolved organic carbon depending on the availability of sorption sites and the microbial decomposition of dissolved organic carbon as being affected by sorption and exchange processes between the solid and the liquid phase. With this respect, we also want to reveal differences in the role of decomposed plant litter in comparison to fresh litter for the cycling of dissolved organic carbon in subsoils.
