DAP NH42HPO4 is a light brown granular phosphatenitrogen compound fertilizer produced by neutralizing phosphoric acid with ammonia
The phosphate is well soluble in water while the nitrogen content is in ammonium form P nutrient availability is ensured for crop rotation at the same time as nitrate fertilization
DAP can be used for all types of crop and all kinds of soil and should be applied during nitrogen fertilization in the spring or autumn
High quality contains fully watersoluble highly concentrated phosphate
Good transport and storage qualities nonhygroscopic nondustforming does not tend to cake
Good spreading behavior thanks to a balanced range of granule sizes
Suitable for fertilizer mixes thanks to excellent granular properties

Diammonium phosphate (DAP) is the world s most widely used phosphorus fertilizer. It' s made from two common constituents in the fertilizer industry, and its relatively high nutrient content and excellent physical properties make it a popular choice in farming and other industries.
The standard nutrient grade of DAP is relatively high, at 18-46-0, so fertilizer products with lower nutrient content may not be labeled DAP.
Usage - agriculture.
Chemical formula - (NH4)2HP04.
Form - granules.
Colour - brown / dark brown.
Diammonium phosphate is a highly concentrated granular complex nitrogen-phosphorus fertilizer. Produced by neutralizing phosphoric acid with ammonia. Diammonium phosphate is a highly effective fertilizer used on all types of soils for the main and pre-sowing application for all crops. The product is used in spring or for plowing the soil, as well as for top dressing during the growing season.
