Ultrasol® MAP

Ultrasol® MAP is an NP source which is high in phosphorous and which is essential for the root development and crop establishment. The phosphate Ultrasol® MAP buffers fertigation solutions, keeping the pH effectively stable at around 4,5.

  • Ultrasol® MAP is very low in chloride, sodium and heavy metals.
  • Is a free-flowing crystalline powder that quickly dissolves in water.
  • Can be mixed with all water-soluble fertilizers other than calcium-containing products.
  • The phosphate in Ultrasol® MAP buffers fertigation solutions, which keeps the pH effectively stable at around 4,5.
  • Nitrogen in Ultrasol® MAP is present in the ammonium form, which offers better control over N availability to plants than urea.
