Potassium for every growing stage!

  • The best source of potassium without nitrogen for all growings phases of plant
  • Ideal for chlorine-sensitive crops such as tobacco, horticulture, vineyard, potato, etc.
  • Free of Chlorine, Sodium and heavy metals 
  • Ideal source of potassium for all crops, especially if they are grown on alkaline soils or are demanding for sulphur or nitrogen fertilizers are not required, usually at the end of the growing season.
  • In alkaline soils, sulphur reduces pH in the roots, helping to improve the availability of phosphorus and certain trace elements such as Fe, Zn, and others.


Potassium oxide (Κ2Ο) 100% Water-Soluble 52%
Sulphur trioxide (SO3 ) 100% Water-Soluble 45%
pH in solute 1% 4,5
Solubility to g/l at 20 0C 124
Suitable for use in organic farming




Nitrogen and phosphorus deficiency in combination with high potassium concentration make it ideal for the application at any stage of growth to supplement the nutrition of plants with potassium.

Way Of Application:

Fertiplant can be applied by fertigation or foliar spray or hydroponic.

FERTIPLANT Potassium Sulphate is suitable for using in organic farming.


FERTIPLANT Potassium Sulphate does not combine with fertilizers that contain calcium.

Not compatible fertilizers can be used simultaneously only in separate dismantling tanks.

We suggest the dissolution of FERTIPLANT potassium sulphate, made before adding any other fertilizer.


Accurate dosing should be obtained after soil analysis and leaf-diagnostics. Take advise from local agronomist.
