It may not help early season but a good hot doe scent durring the rut may get his attention if the wind is right. If I were you I'd concentrate on trying to get permission to where you're seeing them.
I've been out a few times scouting so far and it seems that the deer are liking hanging out on the other side of the field (which is not a place I have permission to hunt right now).
Please elaborate on right now. Have you asked or are you waiting? If you haven't asked I think the sooner the better. I would bring up the fact you see these deer eating out of the owners fields and offer some assistance. The longer you wait and the closer it gets to the season the more difficulty I think you'll have gettig permission.
If you're looking for a cheap fall crop you could pick up some Whitetail Institute Secret Spot for $10.00. It'll plant 3000sq' and as you can see it's pretty cheap. $5.00 for lime and I'd skip on fertilizer since you're soil is probably pretty fertile in IL. Once the beans are harvested this just may do the trick to pull them in.
I guess the bottom line is you can try to lure them in but taking to them will probably be productive. Get on the horn and get permission
