Diammonium phosphate content standard

53%. Diammonium is a high phosphate fertilizer derived from phosphate rock refining, different colors represent the refining of diammonium from different sources of mineral sources, different sources of refined diammonium quality difference is not big, field use almost no difference, and the price of mineral sources are also quite, so the color of diammonium does not determine the quality and price of diammonium, regular diammonium must be marked production process, production process **** there are two kinds of, one is the slurry method, one is the traditional method, in the diammonium packaging bags must be marked, generally located below the words "diammonium phosphate" with a small marking the diammonium content standard. Slurry method, a traditional method, in the diammonium bag must be marked, generally located in the "diammonium phosphate" word below the small mark with the "traditional method" and "slurry method" word Labeling, in the national fertilizer implementation standards is a mandatory requirement. When buying diammonium, its content and whether it is superior, qualified or first-class products determine the quality and price of diammonium. The national fertilizer implementation standards, the total content of diammonium phosphate qualified products is 53%, which contains 14 nitrogen, 39 phosphorus; the total content of first-class products is 57%, which contains 15 nitrogen, 42 phosphorus; the total content of superior products is 64%, which contains 18 nitrogen, 46 phosphorus.
