How is phosphate/phoserous created? How are they recycled?

Rock phosphate is mined from an island in the south Pacific, treated with hydrochloric acid to make phosphoric acid and then further processed to make other compounds. Plants and fungi recycle it on a regular basis.

Phosphate is Phosphorus plus Oxygen. Both are elements that are synthesized from lighter elements within the cores of supermassive stars. These stars then go supernova, spewing these elements as well as many others throughout the interstellar medium. Our solar system contracted from just such a cloud of gas and dust, causing our Earth to have some Phosphorus and Oxygen, which then spontaneously combined to form phophate. Living things figured out that Phosphate was a highly useful substance, causing them to concentrate it in huge amounts. We mine these deposits in order to produce fertilizer for our agriculture. I hope this helps.

nitially, phosphate weathers from rocks. The small losses in a terrestrial system caused by leaching through the action of rain are balanced in the gains from weathering rocks. In soil, phosphate is absorbed on clay surfaces and onganic matter particles and becomes incorporated (immobilized). Plants dissolve ionized forms of phosphate. Herbivores obtain phosphorus by eating plants, and carnivores by eating herbivores. Herbivores and carnivores excrete phosphorus as a waste product in urine and feces. Phosphorus is released back to the soil when plants or animal matter decomposes and the cycle repeats.
The phosphorus cycle occurs when phosphorus moves from land to sediments in the seas and then back to land again. The main storage for phosphorus is in the earths crust. On land phosphorus is usually found in the form of phosphates. By the process of weathering and erosion phosphates enter rivers and streams that transport them to the ocean. Once in the ocean the phosphorus accumulates on continental shelves in the form of insoluble deposits. After millions of years, the crustal plates rise from the sea floor and expose the phosphates on land. After more time, weathering will release them from rock and the cycle's geochemical phase begins again.

Some phasophate comes from islands.
