Biochar is defined by the International Biochar Initiative as the "solid material obtained from the thermochemical conversion of biomass in an oxygen-limited environment".

Biochar is a charcoal-like product made from biomass waste, such as wood or agricultural waste, paper mill waste, or other biological residues. The concept for use as a soil amendment originated in …

Biochar has several unique chemical and physical properties that make it very useful for retaining nutrients and water. Biochar ranges from 50 to 90 percent carbon and less than 0.1 percent nitrogen. …
