Soil carbon management has been promoted as one of the few readily available strategies to mitigate the rising concentration of atmospheric CO₂ and its associated impacts on climate change. One of these carbon management strategies is enhanced rock weathering which involves adding crushed silicate rocks to the soil. The approach requires careful interpretation of the differences between soil organic carbon (SOC) and soil inorganic carbon (SIC) and their measurement, with implications for land management and C credit accounting. In this Opinion, the authors emphasise the distinct nature and fates of SOC and SIC, advocating for their separate management, particularly in C credit schemes.
