0-Till is supposed to preserve 0.5T/ha/yr of C... Crop diversity another 0.2T/ha/yr.
Obviously, if the dirt is blowing, you are doing much damage... but it's not so much zero till as maximizing the amount of time *something* grows on the land... Lots of research.
The more carbon in the air, the more aggressive plants are... which means more carbon is captured and converted to sugar...
A challenge in grain production, especially here where our seasons are too short for many cover crops.
