Roundup Soybeans would be great - and you could prepare & maintain the plots yourself with with a sprayer, roundup and a small set of disks,

You can broadcast soybeans on bare soil, but its better if you can disk them in a bit. You need to KILL the sod off with roundup before planting. You would probably need at least 2 acres - and 4acres would be better - or the deer will keep it browsed to nubs. Soybeans are a great summer plot - and the pods become attractive again when they dry and split in the fall.
