Rye grass is a PITA to get rid of. Deer do not like it.
You can also use milo/sorgum as a nurse/smother crop. What ever you have on hand.
BIG RAIN is the key... I have quit using tractors/disc because it is cheaper to no till and I can control my weeds easier. Added benefit is that you can actually make sandy worn out soil, prosperous again after a few years of no till.
