Biochar is charcoal made from organic matters such as plant biomass and agricultural wastes that can be used to increase soil ability to sequester carbon and simultaneously improve its nutrient contents and water retention.
Biochar is a stable, carbon-rich soil amendment created from the thermal decomposition of biomass heated in a low-oxygen environment. This stabilized form of carbon can be returned to the earth, where it continues to store carbon while improving soil productivity. Biochar can be used in a range of situations, from potting soil to turfgrass applications. By using biochar in their fields, farmers can increase agricultural production without increasing cropland.
