[Stoves] Biochar Projects for Science Students

[Jeff Davis]

Tom,


An exercise in critical thinking:

Two statements....

1. It's claimed that biochar persists in the soil for thousands of
years.

2. Biochar is not normally found in the soil.

Challenge....

How do we prove that there will not be any long term problems with no
turning back. Will we end up with a Frankenstein type soil
(FrankenSoil)?



Best regards,



Jeff
