180: Brian Smith on Biochar

Greg talks to Brian Smith, a transplant to Arizona who needed to improve his gardening results and found out about biochar. Brian explains the process that was used over 2000 years ago, to transform burned wood into a long lasting organic super buffet with nutrients galore. He tells how he was so interested in the results that he took his research to the point that he can now make his own biochar in his backyard.
