Biochar is a fine grained and porous substance produced through modern pyrolysis processes under oxygen free or anoxic conditions at a relatively low temperature 450 c 650 c from a wide. Such a use of biochar is a significant advance over conventional organic matter management as the biochar is more stable in soil and is better able to retain nutrients in combination with sustainable biomass production such a biochar sequestration can be carbon negative and therefore be used to actively remove carbon dioxide from the atmosphere with obvious significance for mitigation of climate changebiochar production can also be combined with bioenergy production through the use of
