Purpose of research: Basic research
Main objective of the project is to characterize the contribution of the mineral parent material to the initial development of element cycles. On the one hand, processes of mineral weathering result in a source function, e.g. for nutrients. On the other hand, the development of reactive mineral surfaces and sorption capacity as well as complexation reactions may increasingly result in a sink function, e.g. for dissolved organic matter. For both functions the interaction with the soil solution as a mobile phase plays a crucial role. We hypothesize that in the initial phase these processes and interactions preferentially occur along existing and developing structures and patterns (e.g. preferential flow paths, surfaces of aggregates and soil skeleton, rhizosphere).
