Discovery of Phosphate in Florida

Discovery of Phosphate in Florida. Some three decades after phosphate rock was first mined in England to be used in fertilizer, Dr. C. A. Simmons, who owned a rock quarry for building stone in Hawthorne, near Gainesville in Alachua County, had some of his rock sent to Washington, D.C. in 1880 for analysis. The rock was determined to contain phosphate.

Phosphorus Sources for Corn Fertilization

Finely ground phosphate rock and colloidal phosphate rock are somewhat effective on acid soils, but only if applied at very high rates. Because of the low P availability, relatively low (30-33 percent) P 2 O 5 content, and problems associated with handling and applying a finely ground material, other P sources made from phosphate rock have been developed.
