Ultrasol® K Plus

Ultrasol® K Plus is the leader potassium source for all growth stages with additional nitrate nitrogen for a quick absorption by the plant. Free of chloride and mixable with all water - soluble sources. This combination makes Ultrasol® K Plus the most all- round and the most efficient water- soluble K- source of its kind.

  • Ultrasol® K Plus is very low in chloride, sodium and heavy metals.
  • It`s a free- flowing, fine crystalline powder that quickly dissolves in water.
  • Can be mixed with all water-soluble fertilizers and it`s also compatible with the majority of pesticides in foliar application.
  • Nitrate nitrogen is non-volatile and enhances the uptake of other cations (K+, Ca2+, Mg2+).
  • Ultrasol® K Plus can be used to cover the potassium needs of a crop without supplying excess of sulphate or chloride.
  • Due to its low N/K ratio, Ultrasol® K Plus is suitable for all crops and growth stages, including flowering and ripening stages
