Soluble Diammonium Phosphate 21-53-0 is a fully water-soluble, high-purity fertilizer in crystalline or fine powder form, designed for fertigation and foliar application. It contains 21% nitrogen in ammoniacal form and 53% phosphorus (as P₂O₅), making it an excellent source of immediately available nutrients during the early stages of crop development. The high phosphorus content promotes strong root establishment, flower formation and energy transfer within the plant, while the nitrogen supports balanced vegetative growth. This product dissolves in water completely without leaving any residue, resulting in a clear solution suitable for all fertigation systems. It is ideal for use in greenhouse cultivation, hydroponics, and precision agriculture.
