Charcoal in the form of biomass is utilized to enhance soil nutrient content and growth environments. Pyrolysis, a process that involves heating and charring woody biomass with little to no oxygen, is one way to make it. By trapping carbon dioxide in the soil for hundreds of years, it absorbs atmospheric carbon.
Biomass has been studied for thousands of years. Ancient Amazonian cultures may have created a crude form of biochar and added it to the soil to aid in the growth of their crops, according to studies of the soil at several locations throughout the Amazon Basin.
Recent research revealed that trees' health was significantly enhanced by the addition of tiny amounts of biomass. Not only did 60% more transplanted trees survive, but they also showed noticeably improved growth, photosynthetic efficiency, and canopy area.
