How to Obtain Red Phosphorus | Sciencing
Dec 15, 2018· Another method used since the late 1700s produces phosphorus from bone ash or rocks. In this method, you reduce animal or fish bones to ash, or you grind up phosphorusrich rocks, such as pyromorphite, and treat the ash or powder with sulfuric acid. The reaction produces phosphoric acid and calcium sulfate.

Inherent Factors Affecting Soil Phosphorus USDA
Phosphorus (P), next to nitrogen, is often the most limiting nutrient for crop and forage production. Phosphorus' primary role in a plant is to store and transfer energy produced by photosynthesis for use in
Phosphoric Acid Essential Chemical Industry
Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H2PO4, derived from phosphoric acid, H3PO4. The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid. Uses of phosphoric acid.
