Why Use Potassium Chloride?


Use Potassium Chloride to maintain and/or build potassium levels in pastoral applications. Applying potassium will enhance clover growth in potassium deficient soils.


Potassium is a key contributor to yield in many crops. Speak to your Dickie Direct Area Manager for more information in regards to your crops potassium requirements.

Products FAQs

When to Use

Autumn, Spring


  • Potassium Chloride can pass through some soils quickly reducing utilisation. To find out if Potassium Chloride is the most efficient potassium source for your soil type contact your Dickie Direct Area Manager.
  • Avoid large applications in the months prior to winter in order to limit leaching losses.
  • Avoid applications on chloride sensitive crops.
  • Where possible apply smaller applications more frequently as opposed to larger one of applications to increase utilisation, i.e. split applications over Autumn and Spring

Potassium’s Role in Plants

  • The main role played by potassium in plants is the balancing of negative charge from anions such as nitrate and sulphate.
  • Potassium is required for protein and starch synthesis and is involved in activating enzyme systems within the plant.
  • Potassium enhances plant quality through shape, size, vigour, and strength.
  • Grasses and clover compete for potassium, therefore low potassium pasture has no clover present and high potassium pasture has a strong presence of both grass and clover.
