The oats will germinate quickly and provide erosion control and browse until your plot seeding comes up, but you'll have to mow it before it goes to seed.Otherwise it could smother your food plot. It's an annual and won't come back. But if the seeds drop, it will re-seed itself. We usually recommend one bushel (32#)/ac.as a nurse crop planting rate. 50# on 3/4 ac. would be a bit much. Half the bag would be about right.
Thanks, Wingbone. I'll go with half the bag.
