The "Black Gold" of Farming: Turning Coconut Waste into Biochar

Biochar is produced through pyrolysis, a controlled burning process with limited oxygen that converts coconut waste (husk, shells, and pods) into a long-lasting soil amendment that can last over 100 years; the drum method uses a 200-liter oil drum with controlled air intake holes, burning for 2-4 hours depending on material, followed by sealing with cow dung and red soil, natural cooling, and activation with beneficial bacteria like Jeevamrutha before application under mulch to create a shelter for soil microbes.
