The biogeochemical cycle describes the fate of phosphorus in the atmosphere, water, and soil. The most common forms of phosphorus found in nature are orthophosphate ions (PO 4 3-).The principal source of phosphorus in the topsoil is the weathering of rock phosphate over a prolonged period during the process of soil …

The Europeans soon discovered phosphate deposits and the tiny island became a strip mine, exploited by foreign colonial powers. After it gained its independence in 1968, mining intensified until most of the phosphate had been stripped and the island's economy went south. In the process of mining phosphate to fertilize fields in faraway …

Phosphorus is a non-renewable resource that is primarily obtained from phosphate rock deposits. The majority of phosphorus resources are concentrated in a few countries, such as China, Morocco, and the United States [3]. This status poses potential geopolitical and economic risks in terms of resource distribution and pricing.

Phosphorus is an essential mineral found in every cell of the human body. Like calcium, sodium, magnesium, potassium, chloride, and sulfur, it is a macromineral. This means you need more of it than trace minerals like iron and zinc. The main purpose of phosphorus is to build and maintain bones and teeth.
