Fosforikiertokulku
Fosforikiertokulku refers to the biogeochemical cycle of phosphorus. Phosphorus is an essential nutrient for all living organisms, playing a critical role in DNA, RNA, and ATP. Unlike carbon or nitrogen, phosphorus does not have a significant gaseous phase, making its cycle primarily terrestrial and aquatic. The main reservoir of phosphorus is in rocks and sediments, where it exists in the form of phosphate minerals.
Weathering of these rocks slowly releases phosphate into the soil and water. Plants absorb dissolved phosphate
A significant portion of phosphorus enters aquatic ecosystems through runoff from agricultural fields, where it is
