DAP (Di-ammonium Phosphate/ Diammonium hydrogen phosphate/ Ammonium phosphate dibasic/Ammonium hydrogen phosphate/ Di-Ammonium hydrogen orthophosphate/ Diammonium Phosphate/Phosphorus ICP standard solution Fluka) is easily soluble in water and used as a high effective nitrogen and phosphate – two of the macro-nutrients fertilizer in agriculture. It is also used in producing NPK compound fertilizers & BB fertilizers as a basic raw material . DAP granular is produced by granulation process for base-dressing, top-dressing for deeply application directly. DAP does not contain chloride and is widely used for all kinds of plants and soil.
