How is the phosphorus cycle different from the nitrogen or carbon cycles?
The global phosphorus cycle has four major components: (i) tectonic uplift and exposure of phosphorus-bearing rocks to the forces of weathering; (ii) physical erosion and chemical weathering of rocks producing soils and providing dissolved and particulate phosphorus to rivers; (iii) riverine transport of phosphorus to …
Because phosphorus is very immobile in the soil, it does not move very far in the soil to get to the roots. Diffusion to the root is only about 1/8 of an inch per year, and relatively little phosphorus in soil is within that distance of a root. Therefore root growth is very important to phosphorus nutrition.
Does phosphorus move in the soil?
Unlike the compounds of other matter cycles phosphorus cannot be found in air in the gaseous state. This is because phosphorus is usually liquid at normal temperatures and pressures. It is mainly cycling through water, soil and sediments. In the atmosphere phosphorus can mainly be found as very small dust particles.

A SOIL-BASED VIEW OF THE PHOSPHORUS CYCLE through the action of rain are balanced in the gains from weathering rocks. In soil, phosphate is absorbed on clay surfaces and onganic matter particles and becomes incorporated (immobilized). Plants dissolve ionized forms of phosphate.
What do the carbon nitrogen and phosphorus cycles have in common?
The phosphorus cycle differs from the nitrogen cycle and the carbon cycle because phosphorus doesn’t have a gas phase as a part of the cycle.
