Ammonium phosphate fertilizer is the compounds containing nitrogen and phosphorus that are usually produced through the neutralization reaction of phosphoric acid and ammonia. At present

there are a variety of products

such as slurry monoammonium phosphate (MAP)

diammonium phosphate (DAP)

industrial grade MAP

water soluble MAP

water soluble ammonium polyphosphate (APP) and so on. After more than 60 years of development

China’s ammonium phosphate fertilizer industry has experienced the road of from scratch and from weak to strong. The successful development of the slurry MAP technology ended the history that the high concentration phosphate fertilizer cannot be produced by using the medium and low grade phosphate ore. The continuous

stable and large-scale production of DAP plant provides sufficient guarantee for DAP products in China. The development of new ammonium phosphate fertilizer products

such as industrial grade MAP

water soluble MAP

water soluble APP

provides technical support for the transformation and upgrading of phosphorus chemical enterprises. In this paper

the production methods

the development history and the latest research progress of ammonium phosphate fertilizers were reviewed.
