[Terrapreta] Where do you get it?

[Greg and April]

There is usually a reason that soils are poor, and if that reason is not addressed, then just adding char, may be just a waste of time, money and effort.

If the soil is poor because of specific climate issues or specific soil chemistry issues - char is not necessarily the answer.

  I see biochar as a very dynamic concept, one that builds on itself and boosts itself; one that can expand "outwards", reclaiming poor soils as it goes along.

      I've raised this question before, and so have others. If we consider the
      large scale production of charcoal, to be used for TP, where is the
      biomass feedstock to come from?

    I certainly think that if a tax is raised on carbon dioxide emissions and the same (or at least a similar) amount is paid to those that sequester carbon (as charcoal, which is 3.77 kg more carbon per kilo as the carbon conten of carbon dioxide), then the wole invention capacity of mankind would be released, and certainly a lot of feedstock would be found.
    I rather think that the inverse problem would occur: that more biomass that the carrying capacity would be harvested. Therefore I think that an (international?) body need to be raised, so that takng out biomass that is damging the ecological system wold lead to a detention of payment, which may imply a use of benign methods.
