field corn is also used in ethanol production, and the stalks and cobs become fodder, which, yes, is also feed, but it’s a highly efficient use of the plant and land, given the outputs.
Sure, but you could also grow food corn, so it’s not really a flaw in this graph.
I don’t think you could grow sweet corn at the same volume/efficiency. if you could, why wouldn’t you? it’s more valuable per pound
Now, I’m not actually a farmer, but I suspect you’re right. You can sell field corn, probably for a similar amount per hectare as food corn, because people will turn around and pay a much higher amount for animal products derived therefrom.
In the scenario presented here that’s basically wished away. The amount of ethanol we use compared to feed has got to be small, so I’m guessing that’s how it all works.
If we all switched to biogas that wouldn’t be true, but electric has won the green power race decisively.
