Biochar is elemental carbon refined from biomass and made cleanly using today's technology. When done responsibly and sustainably, production and use of biochar has been shown to boost crop yields, build long lasting soil fertility, and conserve water.iochar is elemental carbon refined from biomass and made cleanly using today's technology.

Origin of Biochar - Terra Preta. The technique of using charcoal to improve the fertility of soils originated in the Amazon basin at least 2500 years ago. The native Indians of the region would create charcoal and incorporate it in small plots of land from 1 - 80 hectares in size. Terra Preta, as it is known in this area of Brazil, remains highly fertile until today, even with little or no application of fertilizers. And this is in a region of the world known for its highly infertile soils.
