All biochar is not the same
All biochar is not the same, As someone who is building a business on biochar, I can tell you that high quality biochar and campfire leftovers are not the same. An open fire leaves ash, or the inert material in whatever you're burning. Only a tiny percentage would be actual char, and this will give you a small benefit. True char comes from a non-oxygen thermal process and will give you dramatic results.
