Summary: Reservoirs: Rock and soil are the biggest reservoirs of phosphorus. Our mission is to provide a free, world-class education to anyone, anywhere. Biology is brought to you with support from the. Weathering. The phosphorus cycle is a sedimentary cycle (unlike carbon, oxygen, and nitrogen), the atmosphere is not a reservoir for phosphorous nor do microorganisms fix phosphorus as they do nitrogen. This is because phosphorous and phosphorous-based compounds cannot be found in the air in the gas state. Sinks and Sources: Since the phosphorus cycle doesn't involve the atmosphere, there are no sinks and sources. The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere. Phosphorus Cycle Definition. Phosphorus cycle. Phosphorus enters the biosphere almost entirely from the soil through absorption by plant roots. Phosphorus cycle. Biology is brought to you with support from the Amgen Foundation. Khan Academy is a 501(c)(3) nonprofit organization. The atmosphere doesn’t play a substantial role in the cycling of phosphorous. Phosphorus is essential for plant and animal growth, as well as the health of microbes inhabiting the soil, but is gradually depleted from the soil over time. About. The phosphorus cycle refers to the biogeochemical cycle by which phosphorous moves through the biosphere, hydrosphere, and lithosphere. Site Navigation. Donate or volunteer today! However, it is known that the phosphorus cycle is a slow process, consisting of the following steps: 1. When these rocks weather, phosphorus returns to water and the soil. The mechanism of the phosphorus cycle is not as clearly understood as other biogeochemical cycles. Up Next. Rocks are one of the primary sources and reservoirs of phosphorus, where they remain combined with other elements. The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.Unlike many other biogeochemical cycles,the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth. The ocean, rivers and streams are also a large reservoir of phosphorus.
