Turnover and availability of soil organic carbon under different Mediterranean land-uses as estimated by 13C natural abundance

Summary Soil organic matter (SOM) is an important factor in ecosystem stability and productivity. This is especially the case for Mediterranean soils suffering from the impact of humans and degradation as well as harsh climatic conditions. We used the carbon (C) exchange resulting from C3-C4 and C4-C3 vegetation change under field conditions combined with incubations under controlled conditions to evaluate the turnover and availability of soil organic C under different land-uses. The 40-year succession of Hyparrenia hirta L. (C4 photosynthesis) after more than 85 years of olive (Olea europaea L.) tree (C3 photosynthesis) growth led to the exchange of 54% of soil organic C from C3 to C4 form…
