  Carbon isn't nitrogen. The nitrogen needed for agriculture comes from the Haber process. What I'm saying is we can't just give up on the Haber process and go back to "natural" farming without figuring out how we're going to feed everybody.

  ... if it were used as a carbon sink. But that cellulose "waste" part of the corn is a feedstock for other industries. Keeping those inputs constant means growing more of some other crop and increasing net nitrogen usage. Producing nitrogen fertilizer takes energy, currently from fossil fuels.
