The biological, physical, and chemical processes involved in the cycling of phosphorus in the environment. The cycle comprises a geological (long-term) cycle and a biological (short-term) cycle, the latter with both terrestrial and aquatic components (Fig. 1). The phosphorus cycle differs markedly from other nutrient cycles (carbon, nitrogen, oxygen, and hydrogen), because phosphorus has no significant gaseous phase and, therefore, no major atmospheric component to its cycle.
