Well sounds like you have put some thought and work into this project, good to hear and look forward to seeing in up and running, wish I could set one up at where I hunt
as for suggestions for a food plot
well clover is a good idea, as it grows well and last fairly long, BUT it does need come TLC to stay prime, like weed control, mowing a few times a yr, will make it last longer, as will treating it by sprating it for weeds, as if not every yr, or even in one yr, the weeds will over take the plot, and choke out the clover
another good plant, is chichory, it can also be mixed with the clover seed and make for a good mixed crop plot, chichory, tends to last longer /staying greener better after a few front, where clover will pucker up after them, and then the plot will be more attractive later into hunting season, by planting both
best advice is, do it right, do a soil test, add whqt's the test say is needed to get soil at right PH and base line to grow seeds well
kill/burn down the sight well before seeding/too, to help kill as many weed seeds as you Can
be glad to explain how better if you like, but clover/chichory blend would be my suggestion for a plot
