I've maintained food plots on my property for years. To be completely honest though, I am becoming less convinced that they help my hunting much. Here in my part of the country, and I would guess in Michigan as well, by the time the hunting gets good the clover plots have been beaten down by frost and the deer don't use them anymore.
I rent some of my property to a farmer who has corn in one field and soybeans in another, rotating between them every other year. The deer will hit the clover very well during the summer and early fall, but from October on they usually walk right through the food plots to get to the field crops. During the best hunting times of the fall the leftover field crops are the best deer attractant I have on my land.
A couple of things that have worked well for me later in the fall are late planted (August) oats and also brasicas (rape) They don't reach maturity when planted that late of course, but they do stay green well into the fall and do appeal to the deer at those times. But they are not a long term plot, and you need to do something else with it the following spring.
