I expressed some concern when I rotovated the soil in the spring that the smeared soil at the bottom of the rotovated soil may prove difficult for corn roots to penetrate. So I decided to dig up a plant to check. If the roots had a difficult time they would be turned and/or short.
I took these photos June 24th, and am pleased to see that this corn plant appears to have had no problem. By the looks of the rest of the field, its safe to say my fears were unfounded.
