There has been greatly increasing attention given to the potential of ‘biochar’, or charcoal made from biological tissues (e.g., wood) to serve as a long term sink of carbon in the soil. This is because charcoal is carbon-rich and breaks down extremely slowly, persisting in soil for thousands of years. This has led to the suggestion being seriously considered by policy makers worldwide that biochar could be produced in large quantities and stored in soils. (source: slu.se)
