OBTANING OF CALCIUM AND MAGNESIUM PHOSPHATE FERTILIZERS ON THE BASE ON NEUTRALIZATION OF EXTRACTION PHOSPHORIC ACID BY LIMESTONE

The article presents the processes of obtaining calcium and magnesium-containing ordinary phosphorus fertilizers using local carbonate raw materials - limestone. It is established that the use of this method in production leads to the attraction of local carbonate raw materials to produce ordinary phosphorus fertilizers."Science and innovation" international scientific journal.
