"Biochar is a potentially scalable negative emission technology (NET). The negative net flow of carbon is achieved sequentially via photosynthesis which fixes atmospheric carbon into biomass, followed by thermochemical processing of biomass into biochar which converts the bulk of the fixed carbon into stable or recalcitrant form, and finally by the application of the resulting biochar to soil. In addition, this process can result in additional carbon offsets through favorable modification of soil by reducing fertilizer requirement, as well as other secondary benefits. On the other hand, biochar is typically contaminated with traces of organic (e.g., dioxins) and inorganic impurities (e.g., salts) that are detrimental to soil quality."
