Biochar

Biochar is a name for charcoal when it is used for particular purposes, especially as a soil amendment. Like all charcoal, biochar is created by pyrolysis of biomass. Biochar is under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions. Biochar thus has the potential to help mitigate climate change, via carbon sequestration. Independently, biochar can increase soil fertility, increase agricultural productivity and provide protection against some foliar and soil-borne diseases. Furthermore, biochar reduce pressure on forests, though the degree to which results offer long term carbon sequestration in practice has been challenged. Biochar is a stable solid, rich in carbon and can endure in soil for thousands of years.
