[Terrapreta] charcoal making

[Sean K. Barry]

Hi Richard,

You do live in an area of some beauty.  How long after you started the kindling under the split logs was it when you bury the burning pile?  Did you leave any small air intake vents/ output stacks at the bottom or stacks out the top?  Who is the John you refer to?  Are you the two pictured?  Did you measure or estimate the weight of the wood you put into the pit?
Will you measure the weight of the resulting charcoal?  Will you be doing a proximate analysis of the charcoal?

Good luck with your "Terra Preta" making adventure.  I hope you have some interesting results with the pot tests also.

Regards,

  Here is a set of images about our charcoal making project this  
  weekend. It is a smothered pit method, first time for myself . We did  
  open the lower end of the pit after 5 hours and take out about 40  
  gallons , then we put the unburned wood back in and recovered. We  
  will be looking at it again in about 18 hours.

  This will provide us with a charcoal treatment set for our container  
  study on charcoal as a soil additive. Surly we will not make charcoal  
  this way again but we will have a comparison between John's pyrolyser  
  made charcoal to our small holder method.

  This charcoal as well as our other experimental ingredients will be  
  submitted to  a complete analysis routine.

  Larry Williams may have more to say about our project later.
