A team from the United States Department of Agriculture's Agricultural Research Service in partnership with the University of Minnesota has found that the tillage of crops can affect levels of greenhouse gas emissions over a specified area of land.
No surprise. Tillage cuts down on worms and other natural processors of the soil while exposing more of the organic carbon to oxidation. I would be surprised if tillage DIDN'T change GHG emissions, not only of CO2 but also methane and NOx.
