MAP has high nitrogen and phosphorus content and is often used in agricultural production as a basic compound fertilizer.
It is mainly used to prepare compound fertilizer and can also be directly applied to farmland.
As fertilizer, it is most suitable to apply ammonium phosphate during crop growth. Ammonium phosphate is acidic in soil and may have adverse effects if it is too close to seeds. It is better than ordinary calcium and ammonium sulfate in acidic soil and better than other fertilizers in alkaline soil; It should not be mixed with alkaline fertilizer to avoid reducing fertilizer efficiency. If lime is to be used in acid soil in the south, monoammonium phosphate should be applied after a few days.
Phosphate Rock is the raw material to manufacture most commercial phosphate fertilizers. In its unprocessed state, phosphate rock is not suitable for direct application. The process begins by grinding rock phosphate to a fine material. Potash is also fed together with super phosphate to obtain various grades of fertilizers.

Monoammonium phosphate (MAP) is a widely used fertilizer that provides essential nutrients to plants, particularly nitrogen and phosphorus. Here are some key points about monoammonium phosphate:
Nutrient Composition: MAP is composed of ammonium ions and phosphate ions.
It contains both nitrogen and phosphorus, making it a valuable fertilizer for promoting plant growth.
Solubility: Monoammonium phosphate is highly water-soluble, allowing for easy application as a liquid fertilizer or in irrigation systems.
pH: MAP tends to be slightly acidic, which can contribute to lowering the pH of the soil. This can be beneficial in alkaline soils or for crops that prefer slightly acidic conditions.
Fertilizer Use: It is commonly used in agriculture as a source of both nitrogen and phosphorus.
The ammonium nitrogen in MAP is readily available for plant uptake, while phosphorus is crucial for root development, flowering, and fruiting.
Application: MAP is often used as a granular fertilizer that can be broadcast on the soil surface.
It can also be dissolved in water and applied as a liquid fertilizer.
Compatibility: MAP is generally compatible with other fertilizers, and it can be used in combination with them to provide a broader spectrum of nutrients.
Uses in Different Crops: MAP is suitable for a variety of crops, including grains, fruits, vegetables, and legumes.
It is particularly useful for crops that require a balanced supply of nitrogen and phosphorus during their growth stages.
Storage: Monoammonium phosphate (MAP) should be stored in a cool, dry place to prevent moisture absorption and caking.
Environmental Impact: Like other fertilizers, the application of MAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.
Safety Considerations: When handling MAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
