Another option you could consider is soybeans this year and corn next spring. Soybeans can get by without any fertilizer (some would be best) and it will possibly add 30-40lbs of nitrogen to your ground, for next years corn. For a food plot 50-70lbs of soybeans per acre is about right depending on your deer population. If you do decide to plant soybeans, use an inoculate, the correct type should be available where the soybeans are purchased.
Like Soilman said, seed corn will stay good stored correctly till next year.
But I'm still stuck on 80lbs of nitrogen per acre minimum [8D]
