It sounds like you’re on the right road. Don’t worry about trying to remove rocks unless you just have some bolders……build soil over the top of the little ones. I used to hunt a rocky property up in Tallapoosa Co years ago and it seemed like the rocky plots just grew more rocks no matter how many you picked up. Go heavy on some cereal rye this fall and try to grow out a really thick crop of rye hay next spring…..followed by another thick crop of summer grass. Keep giving it some N periodically to keep it pushing out growth and keep your nutrients balanced as you go. Stay patient....
