[Terrapreta] volatile matter and char

[Richard Haard]

Edward - your comment below is a key issue to understanding use of  
charcoal as soil additive in temperate north. I would be interested in  
your comments on the observations Larry and I have had on charcoal re  
our posts moments ago and whether or not you believe pretreatment of  
charcoal before application as Larry is experimenting on is a valid  
approach to this problem.
