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.
Diammonium phosphate fertilizer is a plant food that is rich in the mineral phosphorus. It is widely used among farmers in the production of grain and row crops, such as corn, wheat, rye and some lawn grasses. Some farmers may choose to blend this type of plant food with other fertilizer forms to meet the specific needs of their crops and soils.
