Hi all,

Initial photos from the terra preta trial are posted to 
http://terrapreta.bioenergylists.org/
Thanks Erin and Tom for the upload.

Radish germination was ~one week ago.

Char was mesquite BBQ char (due to availability), crushed and screened 
to 1/8". Presumably high temp. No nutrients were added to the char 
itself. No mycorhizal fungi. Mixtures range from 0-100% sand, soil, and 
char in ~16% increments by volume. 90 pots total. 28 combinations with 3 
pots each + 6 additional pots at 33%/33%/33%. Pots are placed randomly 
in the grid. Radish appears to do much better on pure sand then pure 
char (which is extreme anyway, the middle range will be more 
interesting). Plants will be thinned to the two best (of four) per pot 
this weekend.

The primary data collected will be the final biomass weight. This will 
be collected in a few weeks.

Cheers,
Bear
