I always liked corn - still do - but now I'd rather have Standing Soybeans late in the season with 6"-18" of snow. For me -the deer prefer it over all else. I have no doubt that in the absense of soybeans - corn would do just fine. I found that some years I had to knock it down to get them to use it - but neot if we had decent snow.
Turnips have been turning my head lately. Every year I get more use - but still its usually after hunting season and after all the easy beans and corn are gone - look how they've been on it the last couple weeks though!
