4 Below ground turnover of C and nutrients in forest soils

Chair:

Douglas Godbold (AT),
Ivika Ostonen (EE)

Montag, 10:45-16:35, H17

Belowground C inputs have increasingly been shown to be important for the formation of soil organic matter. In this session we would like to explore the relative importance of above and belowground biomass inputs to SOM, and the contribution of roots and mycorrhizas to formation of SOM. We would also encourage submissions investigating both negative and positive priming, and the role of SOM turnover in tree nutrition.
