Munda tribals living in parts of Orissa, Jharkhand and West Bengal states, in India, use biochar for increasing the crop production. They mix charcoal with farm yard manure (pellets of small ruminants / cattle dung) and add to the red lateritic soils which are other wise less fertile. They cultivate vegetables and green salad in the well fenced plots of about 1 acre in size. The biochar is mostly a byproduct from the biomass cook stoves in use (most often three stone stoves / simple clay earth stoves). They have access to wood from the jungles, which is used as fuel.
