Fast-acting phosphorus and nitrogen dual supplementation with excellent adaptability. As a high-concentration, fast-acting nitrogen-phosphorus compound fertilizer, Monoammonium Phosphate (MAP) features a scientific nutrient ratio and outstanding water solubility. Its acidic aqueous solution (pH≈4.5) makes it especially suitable for alkaline soils, helping adjust soil pH and improve soil structure.
With a high content of water-soluble phosphorus, Monoammonium Phosphate (MAP) can be directly absorbed by crops to rapidly supplement nutrients, promote root development and flower bud differentiation, and enhance crop stress resistance. Produced with high purity, low impurities, and stable chemical properties, the product is easy to store and transport. It serves not only as a premium agricultural fertilizer but also as a valuable raw material for industrial and water treatment applications, delivering excellent overall cost performance.

Contains a high proportion of water-soluble phosphorus that can be directly absorbed by crops without conversion, providing rapid fertilization effects and high nutrient utilization efficiency.
The acidic aqueous solution helps regulate alkaline soil pH and improve compacted soil conditions, making it especially suitable for alkaline and neutral soils.
The scientific nitrogen-phosphorus ratio promotes both root development and branch and leaf growth, delivering synergistic fertilization benefits.
Features stable tetragonal crystal structure, remains stable in air, resists nutrient loss under heating conditions (100–110℃), and is not prone to caking.
Suitable for agricultural fertilization, industrial anodic corrosion inhibition, and microbial nutrient supply in water treatment systems, offering broad application versatility.
Widely suitable for field crops, cash crops, and horticultural crops, especially for alkaline soils and phosphorus-deficient farmland. It can be flexibly used as base fertilizer, topdressing, and foliar fertilizer.
The product effectively promotes strong root growth, flower bud differentiation, fruit setting rate, and fruit quality, while alleviating weak plant growth and yellow leaves caused by nitrogen and phosphorus deficiencies.
Can be used as an anodic corrosion inhibitor in circulating water systems and boiler equipment to effectively reduce metal corrosion.
Used as a nutrient source for microbial culture in water treatment systems, supporting microbial growth and improving treatment efficiency.
Also utilized as an auxiliary additive in food processing, pharmaceutical preparations, and other industrial sectors due to its stable and versatile chemical properties.
Colorless transparent or white crystals with uniform particles, pure color, no visible impurities, and excellent fluidity for convenient spreading and mechanical application.
Solid crystalline texture with high strength and resistance to breakage. Dissolves rapidly in water, producing a clear solution without precipitation or residue.
Manufactured from high-quality phosphoric acid and liquid ammonia through advanced reaction processes, featuring high purity, low heavy metal content, and compliance with national high-quality standards.
Monoammonium Phosphate (MAP) Uses thickened woven plastic packaging with built-in moisture-proof inner film and strong sealing performance to effectively prevent moisture absorption and caking. Clear product labeling and complete information support easy identification and long-term storage.
