What is Soil Carbon?

A major component of the terrestrial biosphere pool in the carbon cycle. It is formed from the decomposition of living organisms whcih themselves contain a high level of carbon. This carbon is relatively stable and can stay in the soil for generations, if not centurys.

How much is there?

Soil contains 2-3 times as much carbon as the atmosphere

Oceans: 38,000 gigatons C (stable, average turnover of a C atom is about 100 years)
Soils: 1600 – 2400 gigatons C (average turnover about 35 years)
Atmosphere: 800 gigatons C (average turnover 5 years)
Biomass: 600 gigatons C (average turnover 10 years)

What about Tetra Petta?

Terra Petta is formed using biochar -the remains from burning organic matter. This was been used by South American people to maintain the productive quality of their soil.

Soil Carbon is formed by the natural process of decay.
