Ron,

 

Thanks for this clarification.  It makes sense.

Robert, etal

 

    Some charcoal in supermarkets is "chunk" and is "pure".  

 

    But all (?) charcoal briquettes (usually the cheaper and more common
form) seem to have considerable non-biomass material, including coal
fines and various waxy materials designed to assist in starting.  These
are cause for concern in soil tests.

	I am interested in understanding how charcoal sold in
supermarkets for barbeque fuel differs from agricultural grade charcoal.
Can someone explain this to me?

	 

	Thanks,
