Does anyone have an accurate listing of WHAT is most likely to yield what kind of contruction materials? I read on another of these forums that wheat is a good place to find nails for example. I am desperate to find some screws for upgrading my silo. I don't mind planting the actual crop IF there is some guide as to which one I need for what!! Please help if you can :) Cheers in advance
