Properties of Biochar Produced from Miscanthus x giganteus and its Influence the Growth of Maize (Zea mays L.)

摘要

In technical terms, biochar, a carbon-rich product, is produced when biomass (e.g. wood, organic manures, and bio-waste materials) is heated (pyrolysed) at temperatures below 700 °C in a limited air supply [1, 2]. Pyrolytical-oil (bio-oil), combustible gases, and biochar are formed during pyrolysis. Our investigations focus on the upgrading of bio-oil (not discussed in this communication), and on the production and characterisation of biochar, and its influences on plant growth when used as a soil amender.
