How phosphate is mined and processed
In a given area of land, plants grow and remove phosphorus from the soil. But then those plants die, and the phosphorus is their tissues is recycled back into the soil. When land is farmed, plants absorb the phosphorus, but then the plants are removed to be eaten. Because this reduces the amount of soil phosphorus available, humans started adding
