اقرأ أكثرThe 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."

اقرأ أكثرThe process of mining phosphate and the production of fertilizers also introduces pollutants into the environment, which alters habitats. The use of fertilizers for agricultural activities typically increases the amount of chemical nutrients in soil or water, especially phosphorous (and nitrogen). These nutrients increase plant and algae growth.
اقرأ أكثر1. 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, …
