Incentivising soil carbon sequestration

Soil contains a huge amount of carbon, twice as much as in the atmosphere in the 0-30 cm layer alone. However, continuous cultivation over a long period has reduced stocks of soil organic carbon (SOC, which I will abbreviate here to soil carbon), often to dangerously low levels. The EU’s Joint Research Centre estimates that some 45% of the soils of Europe have a low or very low organic matter content (0-2% organic carbon). The main mechanism for soil carbon loss is associated with ploughing, due to increased decomposition of SOC due to soil aeration and soil aggregate destruction, increased aggregate turnover and a reduction in aggregate formation.… Read the rest
