The second largest pool of terrestrial carbon is soil CaCO₃. In addition to being an important sink of atmospheric CO₂, soil carbonate is potentially an important source of atmospheric CO₂. The cemented form of soil carbonate-the petrocalcic horizon-develops in geomorphically stable soil in arid, se...
