You can top so on freshly broken ground at a rate of 200 lbs per acre.( at least that is what it was when I lived in Alabama a few years ago. Can’t go over what has already been broken up and can freshen up what has already been sown. I worked from the outside in when I did mine. Divide the field in quarters and do 1/4 each week up to the opener. The week of the shoot you should have fresh dirt and seed in the middle of the field. Best opportunity for everyone to have a crack at birds
