Soil carbon typically denotes the organic matter in soils, known as soil organic carbon (SOC). Yet, there's also an inorganic component to soil carbon, mainly comprising soil inorganic carbon (SIC), which is often calcium carbonate and primarily accumulates in arid regions with poor soil quality. This has led to misconceptions about its significance. A recent study in Science by Prof. HUAN
