Healthy soil and sustainable growing

[Marty Kraft <martyk@allspecies.org>]

I am getting interested in biochar or terra prita. I am interested in  
hearing of anyone's applications to their soil. Did you buy it? Did  
you make it? What was your burner or retort like?

I am working to collect the barrels to make it but might want to buy  
some as well.

Thanks
