Ultrasol® Calmag

Ultrasol® Calmag is a fully water-soluble calcium magnesium nitrate. It combines three nutrients in one product for good plant structure, increased photosynthetic capacity and rapid leaf mass development during the vegetative stage of plant growth. Ultrasol® Calmag shows a fast plant reaction because of the nutrient uptake synergy between nitrates, calcium and magnesium.



  • Ultrasol® Calmag is free of chloride, sodium and heavy metals.
  • Fully Soluble.
  • Is a free-flowing product that quickly dissolves in water.
  • Nitrate nitrogen is the most efficient nitrogen source for plant growth, is non-volatile and enhances the uptake of other cations (K+, Ca++, Mg++).
  • No salt accumulation.
  • Ultrasol® Calmag can be used to cover the magnesium and calcium needs of a crop without supplying sulphate or chloride.
  • Complements water-soluble NPK´s, allowing complete and balanced nutrition with only two products.
