Di-ammonium phosphate (DAP) is a highly water-soluble fertilizer containing nitrogen and phosphorus in a 1:1 ratio. It is a versatile product that can be used in various agricultural settings, including field crops, horticulture, and fruit orchards. DAP is produced by reacting ammonia with phosphoric acid, resulting in a granular or crystalline product suitable for application through various methods, such as broadcasting, banding, or fertigation.
