Short summary
The missing carbon sink is puzzling since carbon cycle is related to global climate. The varying characteristics of soil profile CO2 concentration in carbonate areas and noncarbonates were investigated, together with pH, SOC, and isotope. It is found that carbonate corrosion deeply consumes soil CO2, which accounts for an average of 36 %. Such a process is important for karst carbon cycles and global climate changes, and may be a potential part of the missing sink.
