GRANULAR TRIPLE SUPERPHOSPHATE (GTSP)

CAS NO.： 65996-95-4

STANDARD APPLIED： GB 21634-2008

MOLECULAR FORMULA：Ca(H2PO4)2H2O

Molecular weight：252.07

CHARACTERISTICS：Granular solid of light acidity and moisture absorption, and in color of gray or dark brown. It loses moisture when heated(100℃) and easily caked after being wetted. Because It don’t contain ferric sulphate and aluminium sulphate, it is not easy to produce phosphate degradation.

PHYSICAL PROPERTY：Colorless triclinal crystal or white crystalline powder. Relative density 2.22(16℃), soluble in hydrochloric acid and nitric acid, slightly soluble in cold water, and hardly insoluble in ethyl alcohol. 1.8g calcium dihydrogen phosphate soluble in 100ml water at 30℃, the aqueous solution is acidic and hydrolyzed to calcium orthophosphate after heated. It will lose crystalline water at 109℃ and decompose into calcium metaphosphate at 203℃.

PRODUCT DESCRIPTION：Since the available phosphate content is higher than single super phosphate, the application amount can be reduced according to the phosphorus pentoxide and single super phosphate. It is the single water-soluble phosphorus fertilizer with the highest concentration that is widely used at present. It has high fertilizer efficiency, strong adaptability and has the function of improving alkaline soil.

USAGE：It can be used as base fertilizer, seed fertilizer and complementary fertilizer, also as raw material for compound fertilizers.

USING GUIDE：When using it as a base fertilizer, apply 10 to 80 kilograms per mu subject to the soil texture; when using it as a complementary fertilizer, apply 40- 50 kilograms per mu, and apply it around the roots not directly to the roots. The GTSP performs better when used as a base fertilizer than it performs when used as a complementary fertilizer.

PACKING： In 25KG/50KG/1000KG PP woven bag with PE film liner.
