Excerpt: Biochar or Terra preta is charcoal created by pyrolysis of biomass, and differs from charcoal that its primary uses are carbon sequestration or Bio-energy with carbon capture and storage, can improve water quality, increase soil fertility, raise agricultural productivity and reduce pressure on old-growth forests. Biochar is a stable solid rich in carbon content, and thus, can be used to lock carbon in the soil. Biochar is of increasing interest because of concerns about climate change, thus creating biochar breaks into the carbon dioxide cycle with carbon sequestration. Pre-Columbian Amazonian natives are believed to have used biochar to enhance soil productivity and made it by smoldering agricultural waste. European settlers called it Terra Preta de Indio. Following observations and experiments by a research team working in French Guiana it has been hypothesized that the Amazonian earthworm Pontoscolex corethrurus was the main agent of fine powdering and incorporation of charcoal debris to the mineral soil. Biochar is a high-carbon, fine-grained residue which use...
