With extensive research, real-world examples, and hands-on applications, this go-to guide offers a comprehensive look at the principles and practices of biochar—and all of its world-changing uses.

Like many human discoveries, biochar has likely been invented, lost, and reinvented multiple times. It can be found in the rich terra preta soils of the Amazon and in the ancient “dark earths” dotting Africa, Asia, and Europe. However, biochar isn’t just an archeological curiosity. 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.
