The mineralization of soil organic C is an important process regulating the functioning of natural and managed ecosystems. It controls the fluxes of the soil nutrients. In nutrient-poor sandy land ecosystem, the nutrient turnover and the energy transfer between plants and soils depends in large part on the input of litter and its mineralization in the soil. Information on sandy soil C mineralization and its response to a changing environment is therefore required for better understanding of biological feedb...
