[Terrapreta] charcoal in agriculture

[Tom Miles]

Richard,

 

If you look at a slice of soil mix from each of your test conditions after
the growing season can you see a qualitative difference in the charcoal
itself, or the blend for each fraction? Does the soil in the most productive
mix look different than the least productive mix? Do the results tell you
anything about what the charcoal particle size should be?

 

Thanks for a thought provoking report.

 

Tom
