Diammonium phosphate, commonly referred to as (DAP 18-46), is the world's most used phosphate fertilizer. As a primary nutrient, DAP helps the plant to capture and convert the sun's energy into useful compounds for the plant. It also stimulates root development and enhances the durability of the stems.
Usage: In addition to its wide usage in the agricultural sector, DAP is also used to impregnate matches, and as a flame-retardant (for fighting forest fires).
Diammonium phosphate (DAP) is a widely used fertilizer that provides a high concentration of phosphorus and nitrogen nutrients. It is composed of two ammonium ions and one phosphate ion. DAP is a water-soluble salt and is often used in agricultural settings to enhance plant growth. Here are some key points about diammonium phosphate:
Nutrient Composition: Diammonium phosphate is a good source of both nitrogen and phosphorus, with nitrogen content in the ammonium form and phosphorus in the phosphate form.
The nitrogen in DAP is readily available for plants, while phosphorus is essential for root development, flowering, and fruiting.
Solubility: Diammonium phosphate is highly water-soluble, making it easy to apply as a liquid fertilizer or to dissolve in irrigation systems.
pH and Acidity: DAP tends to be slightly acidic, which can contribute to lowering the pH of the soil over time. It is essential to monitor soil pH when using fertilizers to prevent overly acidic conditions.
Application: DAP is commonly used as a dry granular fertilizer that can be broadcast on the soil surface.
It can also be dissolved in water and applied as a liquid fertilizer through irrigation systems, providing quick nutrient availability to plants.
Uses: Diammonium phosphate is suitable for a variety of crops, including grains, fruits, vegetables, and legumes.
It is often used during the early stages of plant growth to promote root development.
Storage: DAP should be stored in a cool, dry place to prevent moisture absorption and caking.
Safety Considerations:
When handling DAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
Compatibility: Diammonium phosphate is compatible with many other fertilizers and can be used in combination with them to provide a broader spectrum of nutrients.
Environmental Impact: Like other fertilizers, the application of DAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.

DAP is the most concentrated phosphate-based fertilizer. It is perfect for any agricultural crop to provide phosphorus nutrition throughout crop growth and development, as well as starter dose of nitrogen and lower sulphur.
It can be applied in autumn for tilling and in spring during sowing, as well as pre sowing cultivation. Dissolving in soil, it provides temporary alkalization of pH of the soil solution around the fertilizer granule, thus stimulating better uptake of phosphorus from the fertilizers on acid soils. Fertilizer's sulphur also contributes to the better intake of nitrogen and phosphorus by plants.
