[Terrapreta] charcoal making

[Richard Haard]

Terrapreta interest group

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.
