Consequences of agricultural management on soil inorganic carbon; Case study: effect of irrigation on soil inorganic carbon dynamics in the tilled layer (0-20 cm) of Mediterranean agricultural soils
Despite the clear and growing evidence of agricultural management as a driver of SIC cycling with consequences on the total soil C budget, there are large knowledge gaps in terms of quantitative understanding of the processes affecting SIC and its interaction with SOC. If "climate-smart" agriculture is to be promoted, the design of agricultural systems should account not only for their net consequences on emissions or as a C sink but also for other aspects such as their resilience and adaptation capacity to climate change. This includes, in the case of carbonate-rich soils, usually poor in SOC, sustained ability for SOC stabilization, and water storage, for instance. Understanding the interaction of changes in SIC dynamics related to management needs an accurate assessment not only of the amounts of SIC gained or lost but of the changes in the typology and size distribution of stabilization.
