Biochar production Biochar can improve soil fertiliy, retain water and filter contaminants Biochar is produced through a process called pyrolysis, in which agricultural by products such as crop residues or wood waste are subjected to high temperatures in an oxygen-free environment. The resulting biochar is a porous, carbon-rich material that can be used in agricultural applications. Its porous structure enhances water and nutrient retention in the soil, and its chemical stability contributes to carbon capture and improves soil quality. Biochar is characterized by its high porosity and specific surface area, which gives it an exceptional ability to retain water, nutrients, and organic compounds in the soil. Enhances plant and crop growth. Reduces the need for chemical fertilizers. Carbon sink. Improves soil quality and agrobiodiversity. Enhances water retention.
