We had a 2.1 acre bulk area that was soybeans in 2006. We strip tilled every other pass in the fall of 2006. These are the results of the first 5 passes. As you can see there is about a 7 bushel increase for the strip till. Other then strip tilling, the corn was all treated the same. There were more passes but the length got shorter and they were closer to the slough so I did not think they had merit for checking.
