  over the longer term, feeding the bacteria
population by such compounds is only a part
of the picture.  for humus it is the plant
parts that decay which last longer.

  if you have some fires going through at 
times to form some chars then you get carbon in
a more stable form (often with vastly more
surface area for bacterial populations).

  btw, terra preta is composed of more than
just carbon.  it is also evidence of a 
complicated society and large population...
