— Phosphate-solubilizing fungi (PSF) are able to enhance the solubilization of insoluble phosphate (P) compounds. They also have the capacity to mobilize and increase nutrient uptake, produce organic acids and increase the efficiency of phosphate fertilizers, such as superphosphate and rock phosphate (Jyoti et al., 2013; Li et al., 2015).

— Soil characteristics, especially acidity, and calcium and phosphate status, are important: if these are not conducive to dissolution, crop response to rock phosphate is small. Some crop characteristics, especially the extent of root systems and whether they are infected with mycorrhizae, also affect utilization of rock phosphate.
Phosphate bearing deposits were first discovered in Jordan in 1908. It is estimated that more than 60% of the area of Jordan has phosphate-bearing deposits at varying depths. Jordanian Phosphate Mining Company (JPMC) predecessor commenced its phosphate mining activities in the Al Ruseifa area in 1935.
unit for separating phosphate rock mined in Florida begins with wet screening to separate pebble rock that is larger than 1.43 millimeters (mm) (0.056 inch [in.]) or 14 mesh, and smaller than 6.35 mm ... phosphate rock mined from other reserves contains organics and must be heated to 760 to 870°C (1400 to 1600°F) to remove them. ...
— In this study, in vitro and greenhouse experiments were carried out to investigate P and K solubilization traits of nine Actinobacteria (P13, P14, P15, P16, P17, P18, BC3, BC10, and BC11) under fertilization with rock phosphate (RP). K and P solubilization were evaluated on Alexandrov and NBRIP media containing mica and six …
— In order to select Actinobacteria that could improve plant growth and thus agricultural yield, we assessed different plant growth promoting (PGP) abilities of eight rock phosphate (RP)-solubilizing Actinomycete isolates originating from Moroccan phosphate mines. Six of these strains were able to grow on root exudates of the wheat plant as sole …
Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. Pure phosphorus is used to make chemicals for use in industry. The most important use of phosphate rock, though, is in the production of phosphate fertilizers for agriculture. Virtually all common fertilizers have an "N-P-K" rating.
