Hey mossberghunter93, It has not been mentioned, and maybe you already know. Corn needs allot of nitrogen,to get a decent ear. For fairly good ground i use 50 to 100lbs per acre. It usually takes 1lb of nitrogen to get 1 bushel of grain. Nitrogen has came down in price some, but its still high. If you got access, poultry litter is a good alternative. Also, sometimes feed stores that sell Seed corn will have a busted bag they will sell much cheaper.
Grown for grain, 1 bag will plant 2.5 to 3 acres, and will need up to 300lbs of nitrogen.

Hope that helps
