Carbon Farmers have been building equipment to make high quality biochar for many years both in the UK and in Kenya. Biochar has many proven applications in the tropics, but even after all this time we still can't say how best to use it in a UK garden. As biochar is the main reason people buy a Tawi stove, we have decided to try and answer 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.
