Carbon Farmers have been building equipment to make high quality biochar for many years here and in Kenya. Biochar is a valuable resource in East Africa; but even after all this time, we still can't definitively say it is worth making and using in a UK garden. As biochar is the main reason people buy a Tawi stove, we have decided to 'press the pause button' and spend some time trying to resolve this question.
Those who sell biochar and advocate its use in the UK, claim it has miracle-like properties when used as a garden soil amender. Many in the scientific community say there is no credible UK-based evidence to support these claims. With your help we would like to bring more, and hopefully definitive, real-world evidence to the debate.
