If it were me In Indiana I would chisel and then plant a heavy cover crop. I would do 1/3 rye and as many other covers that would work. I wouldn’t chisel again after. IMHO Chiseled or worked ground that has nothing in it (OM) will just default to compaction. At least with a cover you start to get some OM, in soil.
You might consider a winterkill mix (as other poster suggested) the roots of which would retain moisture which would be available for cash crop. I heard that dead roots can retain up to 10 times their weight in moisture.
When I started this I had below avg corn yields for a few years. Now I am even or beating convential yields.
