You don't plant a bag of corn to the acre.
Or use $200 worth of fert.
N is 65 cents a pound here and phos is 900 a tonne.
It's not quite $200 for Fert but it's close.
And a bag does 2.5 acres.
Even so - - - even if you seed 2 bu/acre of barley - - - - maybe that costs you $25 (pricey certified seed which I'd doubt you're using on silage).
So you get 2.5 acres out of a bag of corn seed - - - - what does that bag cost $235 maybe $250 maybe even more.
You have over $200 of difference right there. So your per acre difference is $80 per acre.
With the fertility that makes $280 so at $45/ton your cost is valued at 6 tons of silage.
So you are losing a net of about 1 to 2 tons of silage in value to get the higher yielding crop.
To me that's an easy decision.
Now if you were getting 15 to 20 tons of corn silage you'd me much closer to a par response.
If you couldn't grow barley as well that would also change your decision matrix.
