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.
The two commercial forms of orthophosphates are monoammonium phosphate (MAP) and diammonium phosphate (DAP). Polyphosphate fertilizers contain a variety of polymeric forms mixed with some orthophosphate. Present production capacities for manufacturing ammonium phosphate fertilizers are given and future capacities are projected.
Compound fertilizer can supply comprehensive nutrient for crops. The production process of compound fertilizer is to combine the main nutrient elements needed for crops (such as N, P, K and other trace elements) by chemical method, that is, gather the nitrogen fertilizer, phosphorus fertilizer, potash fertilizer and other chemicals together and make into particles which are suitable for farming.
