[Terrapreta] charcoal in plantings of Jatropha curcas

[Sean K. Barry]

Hi Roy,

It was too your idea, Michael wanted to steal it, you said he could ... to use water power to turn a drum filled and tumbled with too lumpy charcoal and rocks.

You don't get to not acknowledge the credit for the idea.

Regards,

SKB

  Subject: [Terrapreta] charcoal in plantings of Jatropha curcas


  Here in Costa Rica we have a small company (Atlantis Energy S.A.) dedicated to the planting and cultivation of Jatropha curcas, principally to produce biodiesel. We are mostly planting on wet, slopes with worn out soils that were pasturage for cattle. I have always assumed that our soil management would include the advantages of terra preta. 

  The cultivation of Jatropha curcas should include considerable prunning and although these prunings would make poor fuel charcoal, they should be suitable for terra preta uses. Since I assume that the charcoal should be reduced as finely as possible to go in the soil, why not place it in a rolling drum with some rocks to be turned by a small water wheel?

  Another question is the possible use of waste plastics to make such charcoal. As part of household wastes many plastics are of a not recyclable type or are too dirty to recycle. Can these be reduced to charcoal for use in the soil?
