For a acre, I would throw out 100 lbs of oats. They grow well with no maintenance at all. Would do better with fertilizer, 13-13-13 also at 100 lbs per acre, but will grow without any. Will come up 10 days after first rain. Will lay in the ground until the first rain with no problem. However, with oats or anything that you plant you should cover them up. oats need to be 1/4 - 1/2 inch under the ground. A easy way to cover them after you till and broadcast the seed is to simply drive over the plot with your truck pulling a 6"X 6" timber behind you. It will move enough dirt to take care of what you need. But get it in the ground as soon as you can. On second thought, I would plant 150 lbs per acre as being a small plot, it is going to get hammered by the deer, so over seed just a little no matter what you decide to plant. I am not a fan at all of the packaged ready made seed bags that you can buy. I don't think you get your money's worth at all with them.
