  • The phosphorus cycle — Science Learning Hub

    Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43-), located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or plant-eating animals.Phosphate Mining and the Paradox of Abundance Edge Effects,Sep 17, 2019· Similar to other products of the plantation, widespread use of phosphate is accompanied by environmental destruction. Phosphate strip mines produce around 150 million tons of toxic spoil a year, and the ravaged exterior edges of key mining zones—marked by massive draglines, huge slurry pipes, and heaps of waste—are visible for tens of miles.
