Deep soils store more carbon than previous estimates have suggested.
Researchers took extensive samples down to 40 metres below the surface of the highly weathered landscape of southern Western Australia and found carbon in small concentrations all the way to the bedrock, which in total measured up to five times more than commonly reported carbon levels in soils.
The findings may have profound implications for managing climate change as the soil represents one of the world’s largest carbon stocks, and this deep carbon has been previously overlooked.
