The fungi guys will tell you that running out of mineral fertilizer is bullshit on roughly 95% of the arable land because all of the minerals your food needs are right there in the sand and clay. I once heard it described that conventional agriculture is essentially a hydroponics system using partially sterilized soil as the substrate.
Nearly every symbiotic relationship fungi make is based on buying sugars from plants by selling them minerals from biological weathering of rock (particles). What happens in conventional agriculture is that we murder all of the fungi.
There are a few places with strange soil compositions that are actually lacking in particular minerals. We could either elect to do something else with that land, or transition everyone but them to a post-green-revolution strategy.
