Quantifying carbon for agricultural soil management: from the current status toward a global soil information system

Land managers are decision-makers who operate in a broader context that connect their agricultural and financial decisions. Any effort to improve the performance of agricultural soils through increasing levels of SOC requires a feasible and credible assessment of SOC stocks, which are affected by dynamic and complex soil processes and properties. This paper evaluates methods currently accepted to quantify and forecast soil organic carbon (SOC) that, when augmented and pulled together, could provide the basis for a new global soil information system.*
