Biochar: a guide to analytical methods

摘要

Biochar seems to be a bit of a buzzword in soil chemistry and environmental science at present. If you have not heard of the term before, biochar is a type of charcoal produced by the conversion of biomass (hence the name) via pyrolysis. Different forms can be produced for different applications and soils by varying the type of the initial material used as feedstock and/or the pyrolysis conditions (e.g. temperature, rate of heating and oxygen delivery).
