Potassium is responsible for activating plant functions, acting as a catalyst for enzymes to ward off disease and soils rich in potassium increase a plant's resistance to diseases including mould.  Potassium is involved in cell growth by division by combining sugars, starches and carbohydrates. It helps increase chlorophyll and regulate stomata openings thus making better use of air and light.  Potassium is necessary for the production of proteins that augment the oil content which helps improve the flavour of fruit and vegetables and is closely linked to disease resistance and strong healthy root growth.

Deficiency of Potassium

A plant deficient in potassium displays a mottling of the old leaves and a yellowing between their veins.  Potassium is mobile within the plant thus the older leaves will show the deficiency first. The plant can at first seem healthy but is susceptible to disease.

Progressive signs of Potassium deficiency:

  • Leaves of the plant are dark green and the plant appears healthy
  • Branching occurs but they are week
  • Leaves loose their luster
  • Margins of leaves turn grey and tunr a rusty brown
  • Leaves curl up and die
  • Older leaves become yellow and display rust coloured blotches and later drop
  • Mould becomes prevelant
  • Flowering is diminished and fruit drop occurs

Treating Potassium deficiency:

  • Potassium added directly to the nutrient mix is sometimes undertaken hwoever this can sometimes be difficult to achieve
  • Slowly increase the level of potassium in the nutrient
  • Generally foliar feeding with potassium is not recommended
  • In soil based crops added potash is the usual method however care should be taken to adjust the pH as potash is generally very alkaline.

Toxicity of Potassium:

Generally difficult to recognise as symptoms mimic those of others and generally are present when the plant is displaying deficiencies of other elements such as manganese, zinc, iron and magnesium.

Treating Potassium Toxicity:

Flush media with mild complete nutrient solution and if that is not successful a water flush maybe acceptable but not overly recommended.
