I really have to question your financial numbers. I do not know of anyone who would sell corn stalks for that cheap, but if you could give me some names, that would be a very cheap source of fibre/filler for the animals and a very cheap source of bedding. I would value corn stalks at a much higher rate for my own use simply as a fibre/filler or bedding. I have found that the variable costs for baling corn stalks is far lower than $50/tonne and the fixed costs are debatable. By making such an absurd financial assessment of baling corn stalks I also have to question your agronomic knowledge.
