Biochar brings benefits to soils, boosting plant growth - Green guru James Lovelock claims that the only hope of mitigating catastrophic climate change is through biochar - biomass "cooked" by pyrolysis. It produces gas for energy generation, and charcoal - a stable form of carbon. The charcoal is then buried in the ground, making the process "carbon negative". Researchers say biochar can also improve farm productivity and cut demand for carbon-intensive fertilisers. by Roger Harrabin
