Phosphorus (pdf)
Soil Fertility Manual Chapter 4
Murrell, T. ScottPlants must have phosphorus (P) for normal growth and maturity. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement, and several other processes in plants. Symptoms of deficiency may include stunted growth, reduced yield, and various other signs. Soil P comes largely from the weathering of apatite, a mineral containing P, calcium (Ca), and other elements. Phosphorus moves very little in most soils. Several factors affect P availability, including amount and type of clay, time of application, temperature, and other conditions. Placement of P fertilizer is an important consideration. Phosphate rock (PR) is the basic material used in all P fertilizer production. Understanding water solubility of various P fertilizers is important.
