[Terrapreta] Dams & wetter air (Off topic, or not off topic. That is the question.)

[Sean K. Barry]

Hi Duane,

I agree.  At the bare minimum, photosynthesis requires water, CO2, and the right temperature range (above freezing and below what? ignition?)  Without lots of productive photosynthesis, there won't be enough plant material growing for even food maybe, let alone to make charcoal out of it!

Regards,

SKB

    These articles all seem to emphasize the down side of dams. Terra Preta enthusiasts need to keep their eyes on the fact water on land via irrigation or rain is an essential input to the production of the plant material needed to produce the charcoal that will build the soil – while sequestering carbon dioxide.
