Phosphorus is an essential plant nutrient required to assure stable food supply of the global populace. There has been debate regarding the availability of mined phosphorus for future generations. Given that in 2019, the USGS reported that the economically extractable phosphate rock reserves worldwide were 63323359752 million tons, while world mining production in 2018 was 279822649 million tons per year.
