The only time I ever see deer eating corn here, is in the middle of winter, never in season.....or summer when its in a sweet phase. It'll even be left up on stalks in winter and they won't eat it. Not sure why they'll pick over lefterover grain/corn on the ground under snow when its on stalks right there. I hear you about soybeans though I'm not convinced a field of either is much better off. Corn does offer cover, but so does beans, and so does woods.
