Biochar is a carbon-rich material produced through the pyrolysis of organic matter, such as agricultural residues, wood chips, and other biomass. This process involves heating the material in a low-oxygen environment, which prevents complete combustion and results in a stable form of carbon that can be sequestered in the soil for hundreds to thousands of years. The unique properties of biochar make it an invaluable tool for enhancing soil health, improving crop yields, and mitigating climate change.
