The role of biodiversity for storage of carbon and minerals in roots, and aquisition of soil ressources in grassland
Inhalt In this subproject the role of roots for biodiversity effects on productivity and cycling of carbon and mineral nutrients in grassland is investigated. The effects of plant diversity on root characteristics that are related to (a) net primary production and mineral accumulation of  roots, (b) acquisition of soil resources by living roots, and (c) release of organic carbon and nutrients into the soil by decaying roots are assessed in  grassland communities that were experimentally established in the field, or in lysimeters, or in root boxes. It is expected that the results will improve our knowledge about the processes involved in diversity effects on ecosystem functions, and finally may help to develop recommendations of agricultural measures for sustainable grassland management.
