Re: Terra Preta

David:

Thanks for the input. I have seen several 55 gallon drum methods. I was kind of thinking that the burn it inside method would be the best also. I'm glad to have somebody else confirm that. That is what I will try initially.

As far as your suggestion about using lots of drums. I'm not sure that would be practical to produce the large amounts of charcoal needed to do a farming scale test it would take a long time. The wigwam burner is about 150 feet in diameter so I can make a big dense stack of wood and burn it in the middle covering it with earth using my backhoe before I start it. I can drive into the wigwam burner and use the backhoe to work and not do it all by hand. I'm pretty sure if I started it first and them piled on the wood that I could not control it.

My best guess is that I probably need 5 or 10 tons to do an acre. Not something you do a drum at a time I don't think. I could be wrong.

I hope to get a chance to try something soon and I will report back on my results.

Thanks for the ideas.
