Potassium is involved in photosynthesis, enzyme activation, protein synthesis, carbohydrate metabolism, ionic balance of cells and fruit initiation and filling.
Potassium regulates the flow of water through the plant and importantly controls the plants turgidity. Stomata, which are the cells that control the opening and closing of leaf openings, are directly influenced by potassium supply.

Potassium has a direct effect on the plants ability to resist pests and diseases and withstand the effects of low soil water supply.
