Diammonium phosphate (ammonium hydrophosphate – diammophos or DAP) (NH4)2HPO4 is a water-soluble salt formed by the interaction of ammonia and phosphoric acid. It’s a granule of white or gray color, readily soluble in water. It’s physiologically neutral, non-hygroscopic, doesn’t dust and cake.
Diammophos is a universal, non-nitrate, highly concentrated nitrogen-phosphorus fertilizer, in which trace elements are present. The ratio of nitrogen and phosphorus increases the resistance of plants to adverse environmental factors (drought and frost) and diseases. High content of phosphorus contributes to the accumulation of sugar in root crops and fruits.
By the quantitative content of substances in the diammophos it’s a phosphorus-based fertilizer. This makes possible to use it effectively on soils with high acidity, where many other fertilizers are ineffective.
