Agropolychim AD Diammonium Phosphate (DAP)

Agropolychim AD Diammonium Phosphate (DAP) is a complex, highly concentrated, granular mineral fertilizer with excellent physical properties. It contains two main nutrients in its composition nitrogen and phosphoric pentoxide or in total 63% of the 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 the 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 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 unfavorable 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.

Applications & Uses
  • Diammonium phosphate is used for pre-sowing fertilization of winter and spring crops under irrigation conditions.
  • It is suitable for fertilization of soils rich in potassium.
  • Because of the fact that it is water-soluble, it has the properties of fast-acting phosphorus fertilizer, and the low mobility of the phosphorus in the soil allows its use for main, stocking as well as for periodic fertilization.
  • No additional pre-sowing fertilization with nitrogen is needed in autumn crops. It may be applied directly into the soil with the help of conventional equipment for spraying.
