Late Season Liquid Potassium Fertiliser

A highly available, specially balanced potassium fertilizer to improve plant metabolism. Potassium is an essential element for the process of photosynthesis, protein production, water use regulation and transport and activates over sixty enzymes involved in plant growth and fruit production.

Highly effective due to high potassium levels, balanced with phosphate for energy, together with nitrogen and organic components for uptake and efficient metabolism.

Product Features

  • Maintains plant flowering, set and fruit fill during peak periods in high-performing crops when they may not get sufficient uptake to meet demand from the soil.
  • High analysis of essential plant nutrients for growth and yield – 55% by weight are NPK nutrients.
  • Improves plant drought tolerance and resistance to pest attack.
  • Potassium is an important quality parameter including sizing, colour, taste (brix) and shelf life.

Sizes Available

  • 20 Litre
  • 200 Litre
  • 1000 Litre


Both phosphorus and potassium play vital roles in fruiting as phosphorus is key (energy) in many processes that result in cell division, and potassium in the production and translocation of carbohydrates.

The essential traces all play vital roles. Zinc is essential in increasing pollination and enhancing the production of plant growth hormones while boron assists with cell structure including pollen tube development.

Manganese aids in photosynthesis and utilisation of other nutrients, molybdenum has a key role in the utilisation of nitrates into amino acids, copper is a catalyst for many processes including the transfer of sugars, iron is essential in chlorophyll synthesis and cobalt in the production of carbohydrates.
