Um... Why do we need to produce fertilizer? Animals make poop pretty easily and compost just needs to be turned frequently to make something to help plants grow.
Seems to me maybe these companies could adopt regenerative farming techniques is they are really concerned.
You cannot feed 8 billion people with the arable land that we have available without synthetic fertilizer.

Even if we were to Thanos snap the world population and feed those people with only compost/manure/night soil, a large percentage of the labor force would need to go into food production, and cheap food would no longer be a possibility.
Farmers are using all the manure that they have available in the most efficient manner that the market will bear right now and even then I don't know about any for profit farmer in my extension office who doesn't use additional synthetic fertilizer.
