I wasn't really just talking about the ammonia.

Tractors run on diesel fuel, the trucks that move the grain run on diesel, the trains typically run on diesel, the ships typically run on diesel. The plant that processes it into food runs on coal or natural gas, or possibly some hydro power or nuclear. The bag that stores the food comes from natural gas (sometimes oil). Then that package is shipped to a store using diesel. The store powers its lights (also made from a polymer from natural gas) via natural gas generators.

One of fertilizers you point out is ammonia comes as a product from natural gas & it's the only current viable way to do it commercially, at scale.

Sure one day, we may replace all these components, but in-reality it's not anywhere close to being replaced.
