Phosphorus is a fundamental element for all life, yet it does not exist freely in nature but in compound forms called phosphates. Understanding what are naturally available phosphates reveals that they originate from two primary systems: the geological rock cycle and the biological decay of organic matter. These sources form the foundation of Earth's essential phosphorus cycle, a slow-moving process vital for ecosystems and agriculture.

The Earth's crust contains an estimated 0.27% of P2O5, primarily locked within minerals. Naturally, most phosphate comes from the slow and continuous geological processes of rock weathering and biological activity, which ultimately cycles this essential nutrient through our ecosystems.
