Phosphorous (P) is a crucial nutrient in fertilizers, and food cannot be produced without it. The survival of the global population is dependent on it. There is an ambiguity as to the availability of the world's key source of P as its global reserves are being depleted fast. Phosphate rock is limited and concentrated in only a few countries.

Phosphorus (P) is critically needed to improve soil fertility for sustainable crop production in large areas of developing countries. In recent years, phosphate rock (PR) for direct application has been tested in tropical acid soils as a potential alternative to conventional water-soluble P fertilizers like single superphosphate (SSP) and triple superphosphate …

1. Introduction1.1. The importance of phosphorus. Phosphorus (P) is essential for cellular activity making it non-substitutable for life. Worldwide approximately 17.6 Mt of phosphorus was extracted in 2009 from phosphate rock mining operations for conversion and application as fertilizer, and 3.8 Mt for other purposes.Without this supply humanity …

Significant sedimentary deposits of phosphate rock occur in Idaho, Utah, and, to a lesser degree, Wyoming and Montana. The quality of phosphate rock is most often expressed in P 2 O 5 content, and some of the …

Apatite [Ca 5 (PO 4,CO 3) 3 (OH,F,Cl)] is the most abundant phosphate mineral, which accounts for more than 95% of all phosphorus in the Earth's crust and is found as an accessory mineral in most rock …

Phosphate rock is the basis material for almost all phosphate fertilizers, either as such or transformed into phosphoric acid. When added to the soil, phosphate rock slowly dissolves and gradually releases its nutrients. This product is usually used to recharge the pool of phosphorus in soils. Phosphate rock is also used as a raw material for ...
