What? No they don’t. My cousin runs a fertalizer mining operation down south (like, massive massive shit, not a small operation). Phosphorus, nitrogen, potassium, etc. are mined from ore.
I can’t say that nobody minds areas that would be rich in bat guano, but the vast majority of industrial mining operations for fertilizers as far as I’m aware come from mineral sources.
Yeah, but a lot of the mining is mining bat and bird guano, which is animal poop.
Guano reserves ran out by 1900 IIRC. It’s concentrations of nutrients in ancient mineral deposits now (and peak phosphorus is coming).
