[Terrapreta] Terrapreta : chemical description

[Sean K. Barry]

Hi Lewis,

I will look in the Dr. Johannes Lehmann's book, Amazonian Dark Earths; Origin, Properties, Management, and I'll send along what I can find about that subject.

Regards,

SKB

  from       Lewis L Smith  [ energy economist with extensive biomass 
  experience ]

  Does anyone have an empirical chemical formula for any of the major 
  components of a typical Amazonian terra preta or better yet, a drawing 
  of the typical molecules ?

  Thank you.  ###
