“…It is the product of the thermochemical decomposition of biomass at moderate temperatures (350-700°C) under oxygen-limiting conditions (Brassard et al, 2019). Besides biochar, liquid (bio-oil) and gas (syngas) products are obtained from the thermal decomposition (Han & Kim, 2008, Ok et al, 2018, Bartoli et al, 2020. Today, the main use of biochar is as amendment in agricultural soils, because of its high carbon content, stability, porosity and surface area (Brassard et al, 2019, Ok et al, 2015.…”
