In The Biochar Handbook, author Kelpie Wilson argues that the simple process of burning organic material in a low-oxygen, low-emission environment could be one of the most powerful tools we have to restore degraded soils and reduce our dependence on fossil fuels. In accessible and authoritative prose, Wilson demonstrates that biochar is a low-tech but effective means of reducing wildfire risks, restoring soil carbon, managing manure, weaning farms off of toxic inputs, and producing the best compost ever made. 288 pages pb
