I would bush hog first. Depending on what it looks like mid-April, you may have to spray pretty early. Unfortunately, you will not get maximum results without tillage. Is it a Great Plains drill? If it is like the one we used, it's not gonna perform well in compacted dirt. Also depends on soil type.
I'm staying in Dixons Mills. Can't be too far from here. I'm sure y'all got turkey hunters, but if not, I could buy some of that seed for you, for a turkey.
