Biochar, produced in pyrolysis of crop residues, forestry wastes and animal manures, can restore soil fertility while storing carbon for centuries to millennia. Biochar helps soil retain nutrients and fertilizers, reducing emissions of greenhouse gases such as N2O. Replacing slash-and-burn agriculture with slash-and-char, using agriculture and forestry wastes for can provide CO2 drawdown of ~8 ppm or more in half a century.
