Biochar is a charcoal-like substance generated by pyrolysis, a regulated process that involves burning organic material from agricultural and forestry wastes (also known as biomass). Biochar is made using a particular procedure to reduce contamination and properly retain carbon, despite the fact that it looks a lot like regular charcoal. Biochar technology has the potential to mitigate climate change, improve soil quality, reduce waste, and generate energy as a byproduct. The initial positive effect of biochar on soils, manifested by intrinsic nutrient addition, is likely to fade over time. As a result, maintaining agricultural output while using new biochar is a huge challenge.
