'''Biochar''' is a name for [[charcoal]] when it is used for particular purposes, especially as a soil amendment.

Some of the world's most productive soils (e.g. Canadian prairies, Russian [http://en.wikipedia.org/wiki/Chernozem Chernozem] / or "black earth") are very rich in organic carbon. This is now thought to be pyrogenic in origin, likely originating from prairie or forest fires. This carbon is often thousands of years old, demonstrating its stability in soil. For more extensive background on Biochar, please consult the [http://en.wikipedia.org/wiki/Biochar Wikipedia entry on biochar].

===Biochar as a method of carbon sequestration===
The [[earth]] absorbs around 18 times the amount of [[carbon]] emitted by [[humans]] each year.{{fact}}{{w|Carbon cycle}} However, about the same amount (one figure given is 99.9%) of this carbon is released to the atmosphere through [[decomposition]]. This cycle can be closed by a process known as [[pyrolysis]], in which biomass is heated in the absence of oxygen, creating charcoal and locking carbon in the form of biochar.{{w|Biochar}}
