Diammonium Phosphate or DAP (Diammonium Phosphate) is a chemical compound with the chemical formula (NH₄)₂HPO₄. This substance is in the form of white powder or crystalline granules and is widely used as a chemical fertilizer in agriculture because it contains nitrogen and phosphorus, two essential elements for plant growth.

Diammonium Phosphate Properties

High solubility in water: It dissolves easily in water, and therefore plants can quickly use the elements in it.
Rich source of nitrogen and phosphorus: Nitrogen is essential for vegetative growth of plants and phosphorus for root growth and flowering.
Suitable pH: The pH of diammonium phosphate is in the neutral to slightly alkaline range, which is suitable for most soils.
Miscibility: It mixes well with other fertilizers.

Diammonium Phosphate Applications

Agricultural fertilizer: The most important use of diammonium phosphate is as an agricultural fertilizer. This fertilizer is added directly to the soil or mixed with other fertilizers and used.
Water treatment: It is used in water treatment as a coagulant and sedimentation agent.
Food industry: It is used as a buffering agent and pH regulator in some food products.
Other industries: It is also used in the textile, leather and paper industries.

Advantages of using diammonium phosphate

Simultaneous supply of two essential elements: Nitrogen and phosphorus are two main elements required by plants, which are simultaneously provided by diammonium phosphate.
Increased crop yield: The use of diammonium phosphate increases the yield and quality of agricultural products.
Improved root growth: The phosphorus in diammonium phosphate strengthens the root system of plants.
Increased plant resistance to diseases: Plants fed with diammonium phosphate have greater resistance to diseases and pests.
Important points in using diammonium phosphate
Amount of use: The amount of diammonium phosphate used depends on the type of soil, type of plant and weather conditions.
Time of use: The best time to use diammonium phosphate is at planting or during the growing season.
Mixing with other fertilizers: Diammonium phosphate can be mixed with other fertilizers, but before mixing, it is better to consult agricultural experts.
