[Terrapreta] Charcoal- what are the differences that make adifference?

[Ron Larson]

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,
