Biochar
Biochar is a carbonaceous material obtained by pyrolysis of biomass (agricultural residues, forest residues, manure) in the absence or with little oxygen. It has a porous structure, rich in carbon and very stable, which gives it benefits for improving soil, retaining water, and contributing to carbon sequestration.
