Organic-K is a high analysis organic potassium (30%) fertiliser for rapid uptake; also includes plant stimulants for enhanced crop performance.

Organic-K is completely soluble and plant available, delivering the required quantity of nutrients with low application rates.

Potassium is involved in numerous biochemical and physiological processes vital to plant growth, yield, quality and stress. Potassium is essential for translocation of sugars and starch formation; it is also required for leaf stomata opening/ closing, strengthens plants and improves plant resistance to drought and disease. Fruit trees and potatoes have a high potassium requirement.

In organic systems, plants frequently struggle to access sufficient soluble potassium during critical growth stages, which can result in under-developed fruit and grain and severely reduce marketable yields. Organic-K as 30% potassium citrate is a particularly effective form of potassium (Taha 2014). It is used to supplement the potassium crops obtain from the soil
