I'm curious how much fertilizer is used in that acre, and how much fuel was needed to crack the atmospheric Nitrogen to produce the fertilizer.

300 lbs of urea or .65 boe of NG (1 bbl of oil = 20 gallons of gas and 11 gallons of diesel). So let's just say 20 additional gallons of fuel to account for the N

Edit: the land would be planted to wheat if not planted to corn. Wheat uses approximately 80% of the N as corn. The land wouldn't sit idle.
