If you have the time, money, equipment and the acreage, to feed deer with summer plots, then i say go ahead, but if your trying to feed a deer herd with a couple acres, then i don't think its fesible. My density is not real high on my farm, so a couple acres does ok, but in high deer density area's i would be wasting my money. Starting next year, other than my dove field, i will just let my white clover and browse feed my deer until fall.
