How to make biochar
Video demonstrating how we make biochar using the pit method. This is a very simple and quite effective method that anyone can utilise without special equipment or resources. Biochar is charcoal used as a soil amendment for both carbon sequestration and soil health benefits. Although it doesn’t ‘fertilise’ the soil it provides an environment for microorganism growth which in turn provides symbiotic support for trees, vegetables and grasses. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years. Like most charcoal, biochar is made from biomass (usually woody waste) via pyrolysis which is the heating of organic material in the absence of oxygen. Because no oxygen is present the material does not combust but decompose into combustible gases and charcoal.
