WC IL | Using a vertical tillage tool will chop and mix residue to whatever depth you run the tool, usually 2-3" deep. The problem I have seen many times is that means you mix residue directly into the seed zone. Once you have residue in that seed zone you cannot remove it. This can greatly reduce seed germination and will also increase potential of disease to seedlings. Residue in the seed zone leads to poor seed placement, poor emergence, poor germination, and the list goes on.
I have gotten along much better by removing residue from the row before doing any tillage. By running a shallow strip till pass in the Spring we are able to do the amount of tillage that you are wanting with the VT machine but we are doing it at a more-accurate depth since he row would have their own parallel linkage plus we have the ability to manage residue by moving it to the side before the tillage.
It might be worth considering a shallow strip till machine instead of a VT machine.
