The atmospheric concentrations of greenhouse gases have increased to unprecedented levels during last decades, raising concerns about their effect on climate change. Agriculture and land use change play an important role in CO2 emission fixation, especially by affecting the soil carbon (C) storage. In this context, agroforestry systems (AFSs) could contributing mitigation. Given importance olive cultivation Mediterranean region, it is investigate C stock groves, assess which agronomic practices improve these systems. For reason, a study was conducted different including conventional organic management, typical silvopastoral AFS. Furthermore, abandoned grove nearby forest were examined as comparison. Soil samples collected each farm analysed for content physico-chemical characteristics. This indicates that, irrespective groves Umbria region Italy are characterised high level if compared those growing other areas ecosystems, indicating that adopted area not negatively A slightly lower measured AFS comparison farms, while associated with pomace, suggesting practice can be used further increase orchards.
