Monoammonium phosphate is a completely water-soluble crystalline product. It is used as raw material for the production of water-soluble NPK fertilizers for protected ground and open field (in greenhouses, hydroponics, irrigation systems), and as a raw material for the preparation of liquid complex fertilizers. Nitrogen is necessary for the growth and development of the plant biomass, takes part in the photosynthesis process. Phosphorus is necessary for the development of the root system of the plants. MAP is used as a feed supplement for animals. In addition, it is used in industry. Monoammonium phosphate is the perfect flame retardant. Due to its physical and chemical properties, it prevents ignition and burning. Due to complete absence of insoluble impurities, the complete dissolution of monoammonium phosphate is ensured and absorption into impregnated materials such as fabrics, plywood or wood is improved.
