Yeah, you specifically plant feed corn, instead of grocery-type corn. Also why stealing corn cobs off the roadside can backfire.

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
