Any pics? Would help to see the area and how they work together. Couple ways to lay out a good plan are google earth, save the screen image and then open it with the paint program on all windows computers. If not possible a drawn map with on-the-ground pics works. It's important to map out the previaling wind patterns.

For early season you can't beat clover/alfalfa mixes especially if your the only show in town, also they're treadable for you to continue using your ATV trail. For the late season most guys would say brassicas because of the limited size of plot #2 but it takes usually a couple years for deer to hook-up with a new food source. Maybe a mix of clover/alfalfa/chicory, then soybeans and canola(rape seed). Simply disk in the big seed then broadcast the small stuff and pack it with the ATV tires. This wouldreduce the risk and allow you to see if the deer in your area will hit a late season brassica plot.
