CO2 stimulates plant growth, and greenhouses increase CO2 levels at times.
I'm thinkin' I'd read leaving the residue on the ground, allows more of it to break down under the canopy the next year, so you get a some increase of CO2 in the canopy for plant use. Other non-volatile components will end up in the soil anyway, I'm guessing.
