Phosphorite Wikipedia
Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock which contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than

Evaluation of Superphosphate and Rock Phosphate for a
clear advantage over rock phosphate for all crops. Yields for Treatment 2 always were lower than yields for Treatment 6. These treatments apply similar amounts of P over a 6year period. Even doubling the amount of P applied (Treatment 3 compared with Treatment 6) has not been enough to compensate for the lower efficiency of the rock phosphate.

Organophosphate poisoning Wikipedia
Organophosphate poisoning is poisoning due to organophosphates (OPs). Organophosphates are used as insecticides, mediions, and nerve agents. Symptoms include increased saliva and tear production, diarrhea, vomiting, small pupils, sweating, muscle tremors, and confusion. While onset of symptoms is often within minutes to hours, some symptoms can take weeks to appear.

Phosphate rock (phosphorite) mining is the fifth largest mining industry in the United States in terms of quantity of material mined. In 1989 the total production of phosphate rock in the U.S. was estimated at 38 million metric tons (MT). Most phosphate production leads to the making of fertilizers.
PHOSPHORIC ACID (HYDROGEN PHOSPHATE)
The most important phosphorus fertilizer is monobasic calcium phosphate, called superphosphate[Ca(H 2 PO 4) 2], derived by treating rock phosphate with sulfuric acid (or phosphoric acid). Superphosphate is soluble in water and acts as a carrier of phosphorus needed by plants.
