[Terrapreta] pulverizing charcoal

[Greg and April]

No, that was not me, I have never tried to pulverize char with a cement mixer - I don't even have a retort or a cement mixer yet.

  Greg-------Folke may be right. After two years I can't seem to find any of the lump charcoal that I placed in the ground. It appears that the critters and plants are breaking the charcoal up. I would suggest after it has been saturated with soil moisture. Except some small chunks of charcoal remain dry after a year in the soil. Rich has posted a picture of this dry charcoal-------Larry

    Are you sure about that ?

    We already have some evidence that when char level get above a certain level in worm bins, they don't do very well - probably because it's so abrasive.

    If it's abrasive enough to keep worm levels down, what makes you think that the worms can make big pieces small?

    I'm not trying to be rude, I'm just pointing out that we may have some evidence that what you said may not be true.

      The worms and the plant roots  will do the job. After a year, all pieces are conveniently small.
