[Terrapreta] Terra preta postings on arclein blog

[David Yarrow]

actually, i'd like to respectfully disagree with robert.  and yet agree with 
his more fundamental logic that the amazonian natives didn't charcoal trees. 
but they didn't just charcoal corn stalks, either.

i recall nearly 40 years ago i learned how to make earthenware pottery from 
a man who lived many years with the navajo in the southwestern states.  he 
fired his pottery in a pit with cow pies.  i was amazed they would even 
burn, and even more amazed how hot they could get.  then he should me how to 
damp down the glowering pit of redhot cowpies and create a reducing fire to 
turn the pottery black.

when i moved into my 190-year-old farmhouse 10 years ago, i could see the 
soil was wasted, wornout and depleted from the ratty lawn and poor diversity 
of plant species.  my neighbor, who grew up in my house, saw me starting a 
garden and came over to warn me i wouldn't get anything to grow.  i thanked 
him and continued doing what i had learned to do to create fertile topsoil.

these days, i have milkweed, valerian, goosefoot, other weeds that reach 5 
to 8 foot tall, with sout, sturdy stems.  and the bamboo and rosebushes!! 
even my pokeweed grows into giant bushes.  and the trees that once barely 
grew are blooming like mad, making multitudes of seeds which fall on fertile 
soil and sprout like mad into sapling weed trees.  all this before i found 
out about charcoal.

so my once wasted and weak soil is now busting out with bioversity and 
biomass all through the growing season.  i am still amazed how each spring 
when the snow melts, the flat soil erupts in green growth that soon soars up 
to and over my head.  since much of this annual outburst of growth is 
"weeds," i have an abundance of biomass to harvest and stuff in a 
pyrolyer -- or pottery kiln.  long before i get to harvesting cornstalks, i 
could have barrels of charcoal ready to spread -- most of it fine textured, 
and easily crushed into powder without metal tools or power equipment.  and 
absolutely no reason to cut down any trees to make firewood or charcoal.

i seriously, thoroughly doubt the amazon tribes needed to cut down trees 
just to make charcoal.  if nothing else, it was far too much work.
