Emerging ecological and societal challenges require accurate and long-term data for climate studies, agricultural productivity and ecosystem sustainability. Agricultural activities can lead to either losses or gains of soil organic carbon (SOC) in croplands and grasslands. Improved knowledge of SOC pools and fluxes, and greater confidence in the biophysical models used to assess carbon (C) balances in agricultural systems are therefore required by policy makers to implement effective policies on climate change mitigation and adaptation as well as to ensure productivity via ie. soil fertility improvement. Increasing SOC stocks improves soil quality and structure, and is seen as a short- to mid-term solution mitigate greenhouse gas emissions.
