DAP

Diammonium phosphate, better known by the acronym DAP. The nitrogen is in ammoniacal form, which facilitates the absorption of phosphorus. Phosphorus is fully absorbable by plants and is 95% water soluble, which guarantees an excellent agronomic result. 

It is used only in the formulation of NPKs for fertigation and in blended fertilisers as a seed fertiliser when soils are rich in potassium or neutral.
