[Terrapreta] Nothing?

[Tom Miles]

Bakary Jatta,

Well done indeed. And thank for introducing us to the Zai planting holes. I
have put a picture and some links to the zai technique at:
http://terrapreta.bioenergylists.org/
The results described for zai planting holes with manure are quite
impressive.  

We would welcome experience from others. Christoph Steiner has suggested
using biochar in planting holes. I don't know if he has described them in
his dissertation.

Regards,

Tom Miles
