Biochar is a solid, charcoal-like material formed by heating biomass in the absence of oxygen in a process known as pyrolysis. Though not a fertilizer, biochar – when applied to soil – boosts fertility by helping to retain water in the soil when it is dry, and it helps to promote drainage when conditions are wet and retain soil nutrients. This kiln …
