Analysis: 24.9% Potassium, 6.0% Magnesium, 17.0% Sulphur

Bag Size: 1000kg

A naturally mined granular fertiliser containing three essential elements for your crop development, providing immediately available Potassium, Magnesium and Sulphur.


Patentkali is particularly important for peak demand periods for Potassium, where Potassium , Magnesium and Sulphur are required, but Nitrogen nutrition is being kept to a minimum. Potassium is also essential for fruit and vegetable size, sugar and colour development. Additionally, Potassium is important for flower development of fruit trees and ornamentals and fruit size in vegetables. Ideal K-Mg ratio for potatoes, fruits, and vegetables.

Patentkali is naturally mined and contains all nutrients in a rapidly water-soluble and fully plant-available Sulphatic form from natural origins.


Timing of applications are suitable at any time during the season, however Patentkali has a special fit for amending soil Potassium and Magnesium levels and in the later stages of crop development, where nutrient demand is greatest.


The actual rates, number of applications and their timing will vary considerably for different crops and for different districts.  Before application, seek advice from your Campbell’s distributor or your local agronomist.
