    How Phosphate Is Mined And Processed

    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 phosphorus fertilizer to soils in the 1800s. Some of the fertilizer was organic, from ground up bones or mined guano (bat dung). But humans then started mining phosphorus
