"The major challenges with phosphate mining are really price and geopolitical stability," says Yameogo. "It is known that when the price of fertilisers goes up, farmers can withhold buying them." In 2008, the price of phosphate fertiliser unexpectedly increased five-fold. This price spike was caused by a number of factors.

The mining of pebble phosphate began in 1888 in central Florida and in the 1960s in Hamilton County. Today phosphate mining occurs primarily in the central Florida area (Polk, Hillsborough, Manatee and Hardee counties). The central Florida phosphate mining region covers approximately 1.3 million acres of land known as the "Bone Valley."

These different types of phosphate ions can be represented by different chemical reactions. ... Other countries with large phosphate-mining industries include Egypt, Israel, Tunisia, and …
1. Introduction. Phosphorus (P) is a vital biogenic element that plays a crucial role in the biosynthesis of various compounds, such as phytic acid, nucleic acid, and phospholipids, in plants (Bai et al., 2020).It is closely intertwined with key metabolic processes, including nitrogen (N) and carbon (C) metabolism, as well as photosynthesis, …
