Biochar is a soil amendment that is produced when organic waste material is partially combusted in the presence of limited oxygen. Biochar can be used by itself or can be blended with other soil amendments to address a wide range of environmental and agricultural challenges. These applications include improving soil health, remediating polluted soils, sequestering carbon, lowering greenhouse gas emissions, and improving soil moisture.
