Session 7b: Management effects on SOM and ecosystem services

Chair:   Cornelia Rumpel (National Center for Scientific Research, FR)

Ecosystem services such as carbon storage, biodiversity, nutrient and water availability are linked to soil organic matter (SOM), which is directly influenced by land management. Agricultural practices such as fertilization (including organic matter amendments), tillage, and species choice may affect quantity and nature of SOM with consequences for its functioning and the ecosystem services provided by soil. This session welcomes contributions dealing with the effect of land-use practices on SOM formation and turnover at different spatial and temporal scales, highlighting their consequences for SOM dynamics and element cycling. In particular studies relating management effects on the location and composition of SOM to its functions are welcomed.  Contribution of studies assessing innovative management techniques and their impact on SOM and associated ecosystem services are encouraged.
