The phosphorus cycle (article) | Ecology | Khan Academy
The phosphorus cycle is slow. Most phosphorus in nature exists in the form of phosphate ion— PO 4 3 −. Phosphorus is often the limiting nutrient, or nutrient that is most scarce and thus limits growth, in aquatic ecosystems. When nitrogen and phosphorus from fertilizer are carried in runoff to lakes and oceans, they can cause eutrophication ...

A new phosphorus sulphide phase
Abstract. A new phosphorus sulphide phase may be obtained from melts of composition within the range P S P S 6·9. The X-ray powder pattern expands as the sulphur content of the melt falls. It is deduced that the phase is of variable composition. When red phosphorus is used as a reactant, addition of iodine is necessary to give a substantial ...
