Heavy superphosphate (GTSP) abbreviation: three materials, heavy calcium
Implementation standard: GB21634 one 2008
Characteristics: powder, granule
Use:It is a slightly acidic quick-acting phosphate fertilizer. It is a single water-soluble phosphate fertilizer with high concentration and high fertilizer efficiency, strong adaptability, and has the effect of improving alkaline soil. Supply plant phosphorus and calcium, promote the value of germination, root growth, plant development, branching, fruiting and maturity. It can be used as base fertilizer, root topdressing, seed fertilizer, foliar spraying and raw materials for the production of compound fertilizer. It can be applied alone or mixed with other nutrients. If mixed with nitrogen fertilizer, it has a certain nitrogen fixation effect.
Packing:Plastic woven bag (lined with inner film), net weight: 50kg (+/-0.5kg) or 25kg (+/-0.25kg kg) can be customized customer marks.
Other ingredients: calcium, magnesium, sulfur, silicon, iron, sodium, potassium, manganese and other trace elements needed for crop growth. Properties: granular solid, slightly acidic, gray or dark brown in appearance, suitable for long-distance transportation and storage. Soluble in hydrochloric acid, nitric acid, soluble in water, almost insoluble in ethanol. Water loss by heating (100 ℃). Easy to caking after damp. It is more corrosive and hygroscopic than superphosphate. Because it does not contain iron sulfate and aluminum sulfate, it is not easy to degrade phosphate.
Storage and transportation: sealed and stored in a cool, dry warehouse. The packaging must be sealed and moisture-proof. To prevent rain and sun exposure during transportation.
