Diamonium Phosphate (DAP)

Diammonium phosphate (DAP or diammophos) is a complex, highly concentrated, granular mineral fertilizer with excellent physical properties. It contains two main nutrients in its composition — 18% nitrogen (N) and 46% phosphoric pentoxide (P2O5) or in total 63% of active substance. It is obtained through a reaction between phosphoric acid (P2O5) and ammonia (NH3). It is incompatible with other alkaline chemicals due to the fact that its ammonium ions turn into ammonia when they get into medium with higher рH. This product of high quality is easily input into the soils, it is highly soluble, it is not hygroscopic and has a granular form with equal in size granules, which is evenly dissipated along the soil surface.

Advantages

  • It satisfies the needs for balanced input of nutrients depending on the contents of their absorbable forms in the soil;
  • It prevents the lack of nitrogen and provides permanent and complete fermentation. The high contents of phosphorus assist the accumulation of sugar in root crops and fruits;
  • It increases the endurance of the plants to unfavourable factors (drought, cold/frost), and it increases their endurance to diseases
  • It maintains the balance between the vegetative and reproductive phase;
  • It reduces the expenditures for storage, transportation and input into the soil.
