[Terrapreta] Char sorption of water.

[Gerald Van Koeverden]

I am not claiming scientific validity.  Just exploring an  
observational phenomenon that it seems nobody else has noticed.  (I  
haven't had any responses from anyone who says that it doesn't work  
for them.)

It does make common sense that for charcoal to be an integral part of  
soil habitat, that a water continuum should exist between the two.   
Facilitating the transformation of charcoal from hydrophobic to  
hydrophilic (or at least 'hydro-neutral') characteristics might be  
key to establishing new terra pretas more quickly..
