Check with you county agent & land owner of the CRP. In Minn. there are some $ incentives for the landowner to put in food plots. Speak with the landowner and he may let you put in a few plots. Also if you have some tree lines and brush along side the grassy fields that would be a great place for a plot. Some of the older CRP has grown sterile & just don't attract the wildlife much any more. I don't believe feeders are legal in Minn. So your best bet is food plots. For the food plot your best off to put in a good combo seed mix.
