[Terrapreta] eprida char - organic?

[Gerald Van Koeverden]

Sean,

I did a quick scan of those organic farming regulations: the only  
relevant applications I could find were on page 16 under the heading  
"Synthetics allowed."

1.  The only entry for charcoal is "Activated charcoal (CAS #s 7440– 
44–0; 64365–11–3)—only from vegetative sources; for use only as a
filtering aid."

2.  Nitrogen—oil-free grades.

Doesn't look like even straight charcoal would be acceptable to them  
as a soil amendment.  "Terra Preta" is not yet a part of their lexicon.

I don't know what an "oil-free" grade of nitrogen means.
