DAP (Diammonium Phosphate): The fertilizer that quickly became the item of commerce because it had the highest concentration of phosphate and nitrogen at 18N – 46P 2 O 5 – 0K 2 O. MAP (Monoammonium Phosphate): This fertilizer is essentially the same as DAP, but it has a lower concentration of nitrogen at 11N – 52P 2 O 5 – 0K 2 O.
