Amino K™ Product Details

Providing organic amino acids for plants

Amino K is a liquid soil ameliorant providing an amino acid supplement for plants. It is a natural by-product of the sugar industry as the end-product of yeast fermentation of molasses. 


Traditionally, molasses is a good soil food, but only in low volumes. Amino K endows soil microbes with the benefits of metabolites while retaining the more complex chain sugars and brix levels associated with molasses without the limitations, contributing to overall soil health.

Amino K™ Application

Amino K can be applied as a foliar, soil and seed treatment application.It can be applied to all crops across all areas of South Africa.

Amino K™ Technical Information

  • Although molasses has been used as a food source for many years, its primary limitation has been anaerobic spikes during the process of forming sugars which favour pathogens. The yeast fermentation process, however, removes many of these less complex sugars with the corresponding effect of increasing the nutrient and amino acid profile and creating metabolites—a “fast food” source for soil microbes.
  • Amino K°TM encourages the photosynthetic process. The organic amino acids act as instant food and a stimulus to microbes. This stimulus produces carbon dioxide in the soil, leading to increased photosynthesis once it is captured in the plant leaf, sending metabolites back to the roots as polysaccharide organic acids, which further propagate the cycle.


The main ingredients of Amino KTM are:

  • Amino KTM contains 4% potassium and other macro and micro elements – especially silicon and enzymes – which increase plant vigour when applied to the soil through irrigation systems.
  • In combination with consortia microbes (lactobacillus, yeast, etc.), Amino KTM facilitates the breakdown of organic matter, returning it to the soil.
  • Amino KTM is balanced, allowing for buffering of inorganic fertilisers which are inherently associated with a high salt index.
  • Amino KTM is popularly applied with inorganic fertilisers through a pivot and is predominantly applied to the soil just prior to planting and then throughout the crop cycle. Zylem will happily advise on crop-specific requirements and applications.
Available in 1000L flow bins and tanker loads.

Frequently Asked Questions

Amino K is a liquid soil ameliorant that acts as an amino acid supplement for plants. Amino K is formed as a natural by-product of the sugar industry. It is the end-product of yeast fermentation of molasses.

Amino acids act as an organic fertiliser and stimulant. They contain natural chelating agents that ensure nutrients and minerals are delivered in readily available forms for plants. As a plant protein hydrolysate, amino acids provide an organic source of nitrogen and plant stimulants. Amino acid fertiliser provides a building block of plant proteins and helps regulate essential plant functions. 

Studies have proven that organic amino acids can directly or indirectly influence the physiological activities of the plant. Adding organic amino acids to the soil helps improve the microflora of the soil and subsequently facilitates the assimilation of nutrients.


Amino acid supplements are readily absorbed, transported, and utilised as a source of nitrogen and carbon for plants. They also function as biostimulants for plants, enhancing plant productivity under stress conditions.

Adding amino acids to the soil provides plants with a protein source. As a biological food source for plant and soil microbes, amino acid fertilisers also help increase nitrogen content. Plants are able to pick up amino acids from the soil to receive organic nitrogen. Amino acids also act as a natural chelating agent.
