All fertilizer phosphorus comes from phosphate rock tricalcium phosphate The phosphorus in the rock is not readily available to crop plants because the natural rock contains 1 to 3 percent of fluorine and this makes the phosphorus soluble with difficulty Nevertheless it has been and still is the practice to grind the rock very finely and
Bases of the production of phosphoric fertilizers are classical methods involving acid dissolution of rock phosphates The development of new methods applicable both to high quality and low quality phosphates is important for solving technological and ecological problems and to increase the economical effectiveness of phosphorus fertilizer technologies In this
The level of potentially toxic metals in the phosphate rock depends on the type and the origin of the phosphate rock whereas; sedimentary phosphate deposits possess much higher concentrations of
