2.2. Factors affecting the properties of biochar. The yield of biochar and its physicochemical properties such as surface area, pore size, carbon content and functional group depend mainly on the pyrolysis process conditions and the type of feedstock used for its preparation (Manyà, 2012, Zhao et al., 2013).Also, these parameters strongly …
Creating biochar actually reduces CO2 in the atmosphere because the process takes a theoretically carbon-neutral process of naturally decaying organic matter and turns it carbon-negative: When plants decay, they emit CO2, which other plants eventually absorb, and the cycle continues. Biochar stabilizes that decaying matter and …
Straw biochar amendment has a strong adsorption capacity and is a valid means for improving the effectiveness of soil nutrients. Straw biochar can participate in the nutrient cycling process by interacting with soil, such as adsorbing various nutrient elements on the surface (i.e., N, P, and K) and enabling ion
