Biochar properties

WebJun 29, 2024 · Biochar is the solid product of pyrolyzing biomass under the temperatures of 300–700 °C with limited oxygen (Lehmann and Joseph 2015).Biochar includes artificial biochar and natural biochar (usually formed by wildfire), and has a large range of physicochemical properties that are determined by pyrolysis condition and feedstock type. WebJan 8, 2024 · Biochar is a stable form of carbon and can last for thousands of years in the soil [ 40 ]. It is produced for the purpose of addition to soil as a means of sequestering carbon and improving soil quality. The conditions of pyrolysis and the materials used can significantly affect the properties of biochar.
