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 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. …

As the first journal specifically focusing on biochar, the journal Biochar covers multidisciplinary subjects of agronomy, environmental science, and materials science.
