K-Rich involves potassium citrate – a buffered, super-available form of potassium which can alleviate typical problems with potassium uptake which are often pH-related, due to the inherent alkalinity of this element. K-Rich has been specifically designed for foliar fertilizing of grain, vegetable and fruit crops during the potassium-hungry fruit/seed-fill stage.


What can K-Rich do for my crops?

Potassium (K) is involved in numerous biochemical and physiological processes within the plant which are vital to plant growth. 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. Therefore, consistent availability of this critical nutrient can have profound effects on yield, quality and stress tolerance and resistance. 


In all crop production, it is important to provide the nutrient requirements of the crop to gain sufficient yields and maintain the fertility of the soil. Insufficient soluble potassium during critical growth stages can result in under-developed fruit and grain which severely reduces marketable yields.


While potassium is needed by all crops for proper development and production, fruit trees and potatoes have a particularly high potassium requirement. Fruit, vegetables and grain crops require increased potassium during fruit/seed fill stage to aid filling, ripening and colour formation. This is because there is competition for energy between developing fruit and vegetative growth which may limit root growth and nutrient uptake, including K.


Applications of K-Rich can help meet the crop's increased demand for potassium at critical growth stages.


While K-Rich has been designed as a foliar, it can also be effective when applied in irrigation.


What's in K-Rich?

K-Rich is a highly plant-available form of potassium that facilitates energy transfer, can improve stress tolerance, and improves colour, quality, yield & storability. K-Rich is a super-available, citrate-complexed source of potassium containing over 30% potassium, ideal for optimum flower/fruit/seed production. K-Rich comes in a clear formulation suitable for all crop stages.


How should I use K-Rich?

K-Rich should be used as a foliar on broadacre, vegetable, turf, ornamentals, orchards, vineyards, and pasture at a rate of 1 - 3 L/ac, depending on crop and timing and based on the results of tissue analysis.


Do not spray if copper hydroxide residue may be present.
