The trees—native to Kenya—are one of the first fruit trees shown to have this ability, known as the oxalate carbonate pathway. All trees use photosynthesis to turn CO2 into organic carbon, which forms their trunk, branches, roots and leaves; this is why planting trees is seen as a potential means to mitigate CO2 emissions.Some species of fig trees store calcium carbonate in their trunks—essentially turning themselves (partially) into stone, new research has found. The team of Kenyan, U.S., Austrian, and Swiss scientists found that the trees could draw carbon dioxide (CO2) from the atmosphere and store it as calcium carbonate ‘rocks’ in the surrounding soil.The inorganic carbon in calcium carbonate typically has a much longer lifetime in the soil than organic carbon, making it a more effective method of CO2 sequestration. What was your take on using calcium carbonate ‘rocks’ in the surrounding soil to rehabilitate our soil ?
