I always plant a few acres of corn, just walk down a row and drop it on the ground, then run over with a drag or lightly disk. Can plant a field in less than a hour and I am elderly. I get my seed from Pheasants forever ( others might have it) for about $15 a bag, soybeans too, as well as wildlife mixes but those are more costly. Whatever you do go to a farm elavator or store, don't buy the package stuff.
