Yes, there is, you rotate your crop with legumes. There are also crops that gather stable phosphorous and activates it, but those tend to be long-lived and thus bad for rotation.

What I don't get is why the focus on fertilizers? There may be some wisdom on not spraying random poisons on the stuff you are going to eat¹, but the worst you can get with fertilizers is soil salinization, and this is perfectly avoidable on any place that isn't a desert already, and there are ways to avoid it on deserts too, just a bit more expensive.

1 - So there's a reason for a poison by poison discussion, the overall label of "organic" just poisons the discussion.

I assume the focus is on ensuring long-term crop viability even if we manage to deplete easily accessible mineral deposits used to provide phosphates or whatever. Personally I say we liberate everything we can from the ground, including carbon.

How do the crops you mention “gather phosphorous”? From where?
