[Terrapreta] Dynamotive demonstrates fast-pyrolysis

[John D. Wilson]

Increased respiration doesn't mean increased net emissions. If increased
biological activity is associated with increased net emissions, then
eventually all the carbon in the soil would be gone. Compost amended soils
increase net emissions because dead organic matter is added to the soil and
it is gradually decomposed resulting in a net loss of carbon. Eventually the
compost is mostly gone and then the net increase in emissions stops. In
contrast, the char appears to fuel decomposition briefly, but then
stabilize. At that point it does not provide a net source of emissions.

Hi Sean,
 
The only work I recall was the asian work showing , i think it was 1/3
reduction in Methane and 1/4 reduction in N2O with even low amounts of char.
 
I have not seen measurments on CO2 emissions , It's my assumption that the
increase of microbes, fungus, tilth, Glomalin, humus, soil respiration and
general biomass in TP soils food chain would increase CO2 soil emissions.
Just as compost amended healthy soils do.
