Although exact quantities are difficult to measure, human activities have caused massive losses of soil organic carbon.

Much of the contemporary literature on soil carbon relates to its role, or potential, as an atmospheric carbon sink to offset climate change.

Despite this emphasis, a much wider range of soil and catchment health aspects are improved as soil carbon is increased.

Permafrost affected soils cover nearly 9% of the earth's land area, yet store between 25 and 50% of the soil organic carbon.

Increasing temperatures facilitate the transfer of soil carbon to growing vegetation on the surface.

Heavy root production holds the soil in place and restores its natural fertility by increasing the soil carbon.

Our material needs are all supplied by the moon's soil, except for the light elements-hydrogen, carbon, and nitrogen-which the moon does not possess.

These can quickly stabilize the soil, place carbon into the ground, and protect the land from drying.

This reflects an increase in the level of soil organic carbon, cation exchange capacity, available plant nutrients and exchangeable bases.
