FoliMAX Vigor-K is a chloride free, high potassium citrate/carbonate complex formulation, designed for maximum nutrient uptake into the plant. FoliMAX Vigor-K contains a high potassium analysis (30%) for correction of K deficiencies in turf and landscape plants. Vigor-K is a useful product for use in autumn for conditioning the plant prior to the onset of winter. FoliMAX Vigor-K is tank mix flexible with most soluble and liquid fertilisers and is ideal for use in combination with FoliMAX N-hancer-N to obtain a desired nitrogen and potassium output. FoliMAX Vigor-K offers you a reliable and robust high potassium fertiliser that will become an integral part of your turf liquid nutrition program.

The potassium citrate/carbonate complex explained

The potassium in FoliMAX Vigor-K is present as a citrate/carbonate complex. Having dual forms of potassium optimises availability of the nutrient, both via the leaf and the soil. The potassium citrate component provides a citrate molecule which is found in all plants, and this form of potassium is immediately recognised and assimilated by the plant maximising leaf uptake. The potassium carbonate form is ideal for plant uptake in the soil environment and also has the additional benefits of enhancing disease resistance properties within the turfgrass plant.

FoliMAX Vigor-K : Low salt index of potassium sources

Higher salt index fertilisers have a greater potential to cause foliar burn. The lower the salt index, the lower the potential for phytotoxicity. Both potassium carbonate and potassium citrate have very low salt index and as a result, FoliMAX NRG-NK has a very low potential for foliar burn after application.

 Product Salt Index
 Potassium chloride 120.1
 Potassium sulphate 42.6
 Potassium thiosulphate 68.0
 Potassium nitrate 69.5
 Potassium carbonate <20
 Potassium citrate <10


The importance of potassium in turf management

Turf grasses require potassium in relatively large amounts, second only to nitrogen. Potassium is referred to as the turf ‘toughener’ and its main purpose is to improve stress tolerance within the plant. It is an ideal element to be used in conjunction with nitrogen, as while N produces cell growth, potassium strengthens the walls of the cell, hardening it to stresses such as disease and pest infestation. Potassium is also important for many plant processes and it performs the following functions within the plant:

  1. Regulation of the opening and closing of the stomata, which effectively improves heat and drought tolerance.
  2. Production of proteins and carbohydrates. Potassium also assists in moving these compounds throughout the plant. This becomes very important for winter survival and recovery.
  3. Controls uptake of certain nutrients.
  4. Increases root development, enhancing greater branching of the root system. This contributes to improved drought and wear tolerance.

What is SRN-IQ technology and what does it do?

The SRN-IQ Nitrogen technology is a true liquid, clear urea-formaldehyde solution which has an oily, resinous quality. The SRN-IQ Nitrogen technology has a linear molecular structure, which allows it to be more compact than other slow release nitrogen technologies, and therefore provides it with significantly improved foliar uptake capabilities.

  • Rapid plant uptake
  • Slow release nitrogen
  • Enhanced soil activity
What is NutrexTM Delivery Technology and how does it work?

Nutrex™ Delivery Technology is a novel technology designed to enhance foliar uptake of liquid nutrition products and optimise internal mobility of the applied nutrient. This vastly improves the efficiency of applications of fertilizer formulations containing the Nutrex™ Delivery Technology, resulting in minimal nutrient loss and optimum plant response.

  • Enhanced uptake and nutrient delivery to the plant’s vascular system.
  • Integrated surfactant package for optimised surface spreading, further enhancing foliar uptake.
  • Natural humectants within the formulation prolong drying time on the leaf to extend the uptake window.
  • Improves internal mobility of applied nutrients, getting the nutrient to where it needs to be faster, and with less expense of energy to the plant.
  • Provides a source of energy to the plant as the carbohydrate is metabolised internally.
