In my reading it sounds as though the secret of biochar is really nothing more than massive surface area. The stuff becomes more beneficial to the soil as it becomes colonized by millions of microbes that all help the soil become healthier. It really isn't that drastically different than why running pond water through fine filtration can help improve water quality.
I'm not buying that I have to buy this stuff from anyone. I make nice black charcoal in the fire pit everytime it smother a fire and that's my biochar.
