Buried Fossil Soils From Long Before Industrialization Are Deep In Carbon

Soil from thousands of years ago that is now deeply buried has been found to be rich in carbon, adding a new dimension to figuring out the planet's carbon cycle. The element carbon comes in many forms and cycles through the environment – land, sea and atmosphere – just as water in various forms cycles through the ground, oceans and the air. Scientists have long known about the carbon storage capacity of soils, the potential for carbon sequestration, and that carbon in soil can be released to the atmosphere through microbial decomposition. read more
