Hi Folks,
I posted on this group site a while back about soil reclamation using ancient techniques - one of them was "terra preta" aka bio-char which is being researched a lot now for creating an almost miracle-like living matter in the soil. Deane's son and his lovely companion are traveling around the US highlighting all things green and found and interviewed a gentleman who creates bio-char and explains why it is so useful.

Hope this gives you some helpful ideas. This is just one way of creating bio-char. Do some of your own research and see what you come up with :-)
