A sane reaction to increased fertilizer prices would be a reduction or elimination of requirements for ethanol additives to gasoline. This would at least match drops in feed in tariffs for wind and solar electricity and give the appearance of balance and a coherent 'no subsidies' approach, which, in itself, would be a novelty.

There are hard limits to how high ammonia can go - It is the most widely synthesized chemical on earth, and natural gas is most emphatically not a necessary ingredient. There are producers right now making money producing it via the electrolysis pathway in places with cheap electricity. I think this is due to a cartel in ammonia production, because the level of profit that implies for people producing it the lazy way is hard to explain without a cartel limiting production - but it does mean that if ammonia goes much higher a lot of people are going to start turning electricity water and atmospheric nitrogen into fertilizer.
