Product Brief Introduction: MAP is a water-soluble quick-acting compound fertilizer and one of the main varieties of high concentration phosphate compound fertilizer. Its total effective nutrient content amounts to over 55-66.0% and the content proportion between available phosphorus (AP2O5) and total nitrogen (TN) is around 5.44:1. It is mainly used as topdressing and is the primary basic materials for producing multi-nutrient compound fertilizers and BB fertilizers. This product is extensively applied to various varieties of grain crops and cash crops including paddy, wheat, corn, sorghum, cotton, gourds, fruits and vegetables. It is extensively suitable to many soils of different properties such as red earth, yellow earth, brown earth, yellow wet earth, black earth, cinnamon earth and purple earth etc. It is especially appropriate for dry areas with little rain in northwest, north and northeast China. Major Technical Specifications: For Granule MAP (60%), Total nutrient (TN+ AP2O5) content≥60.0%, total nitrogen (TN)≥9.0%, available phosphorus(AP2O5)≥49.0%, water soluble phosphorus (W P2O5/ AP2O5)≥90.0%, free water≤4.0%, granularity of granule products (2-4mm)≥90.0%, and average granule compression strength≥30.0 N/per granule. For other products and their specifications, please refer to the packing bags or consult through the business telephone.Illustrations on other product Ingredients: Products also contain intermediate and trace elements necessary for crop growth such as calcium, magnesium, sulfur, silicon and iron. Product Identification: GranularCriteria Implemented: (GB 10205-2001)Granular Brand: Sanhuan Brand Outward Appearance: Granular solid with gray color Power Brands: (Sanhuan Brand, Yufeng Brand and Golden Furui Brand)Outward Appearance: White or light-colored powder without distinct crystallization. Major Product Ingredients: NH1H2PO4Product Hazard or Harmful Ingredients: This product does not combust or explode. It is poison-free and harmless to health.Product Physical Properties: White powder or granules (granular products have high granular compression strength); It is neutral and the density is 1.80g/cm3 and pile density around 960-1040kg/m3. It dissolves well in water and acid. Powder products have certain hydroscopic property.Product Chemical Properties: It is stable under normal temperature without redox. It does not combust or explode when it is under high temperature or contact acid base and redox materials.Spillage Treatment Method: Simple cleaningProtection Measures for Product Transport & Storage: To prevent from caking and going bad, it should be kept indoor or be covered with protection materials like canvas and free from the blazing sun.Other Explanations: Powder products produced by high quality phosphoric rock through phosphoric acid concentration process are classified as Class I MAP while those produced by medium or low quality phosphoric rock with high content of magnesium, iron and alumina through slurry concentration process are classified as Class II MAP.
