To add: I want to stress the phosphorus is used by all livings things part.

Plants get phosphorus from soil, animals get it from plants, predators from other animals, and finally microorganisms from our all remains. But it all starts with plants. We cannot grow "low phosphorus" food plants or anything. It's used in ADP and DNA synthesis! Phosphorus sits at the core of life itself. Every living cell on earth depends on what plants can extract from soil.
