Purpose: Diammonium Phosphate  is a Agricultural Grade Phosphate and Tech Grade Phosphate mainly used as a high concentration nitrogen phosphorus compound fertilizer;  Industrial grade is used for impregnating wood and fabrics to increase their durability. It can also be used as a dry powder fire extinguishing agent and phosphorus for fluorescent lamps; It is also used for printing plate making, manufacturing of electronic tubes, ceramics, enamel, etc., and biochemical treatment of wastewater.

Diammonium hydrogen phosphate (DAP) is a type of fertilizer that contains the essential nutrients nitrogen and phosphorus in a highly concentrated form. It is a granular fertilizer that is easy to handle and apply, making it a popular choice for farmers and gardeners. 

DAP is made by reacting ammonia with phosphoric acid, resulting in a white crystalline substance. It has a high nitrogen content, typically around 18%, and a phosphorus content of around 46%. These two nutrients are essential for plant growth and development, with nitrogen promoting leaf and stem growth and phosphorus promoting root development and flower and fruit production.

DAP is commonly used on crops such as corn, wheat, and soybeans, as well as in fruit orchards and vegetable gardens. It is often applied before planting or during the early stages of growth to ensure that plants have access to the nutrients they need to thrive. DAP can be applied directly to the soil or mixed with water and applied as a foliar spray.

While DAP is an effective fertilizer, it is important to use it responsibly to prevent environmental damage. Overuse of nitrogen and phosphorus fertilizers can lead to runoff and pollution of waterways, which can harm aquatic ecosystems. Farmers and gardeners should follow recommended application rates and timing, and consider using alternative fertilizers or organic farming methods to minimize their environmental impact.
