Monoammonium phosphate


Monoammonium phosphate (MAP) is a granular phosphate-nitrogen fertilizer. The phosphate is well soluble in water, and the nitrogen content is in ammonium form. MAP is an effective universal fertilizer which can be used for all types of crop and all kinds of soil. However, MAP is particularly suitable as an under-root fertilizer in crops with a high P requirement (e.g. corn). Through the high ammonium content, the phosphate intake is promoted during under-root fertilization.

The advantages at a glance

  • Good transport and storage qualities: non-hygroscopic, non-dust-forming, does not tend to cake
  • Good spreading behaviour thanks to a balanced range of granule sizes
  • Also suitable for fertilizer mixes thanks to excellent granular properties
