Liquid Fertilisers

A range of benefits for the end-user


Farmers understand that relying on conventional farming practices is no longer adequate when it comes to achieving an optimum return on crop yields. Four decades of scientific trials, conducted in over 70 countries, prove that Kelpak Liquid Fertilisers consistently improve plant growth and development from germination and rooting, through to fruit production. Containing several macro and micro elements, Kelpak Liquid Fertilisers are manufactured from freshly harvested giant Ecklonia maxima kelp using the proprietary Cold Cellular-Burst process to extract a natural, liquid seaweed concentrate while preserving the delicate natural elements contained in the cells.


Scientifically proven

Our Liquid Fertiliser products are manufactured using tried and tested methods, to ensure consistent results when applied to crops. As they are entirely natural and water soluble, Kelpak products can be safely used in conjunction with crop protection and fertiliser programs.

  • Root Growth

    Not only does Kelpak encourage growth of the primary root tip, the active ingredients also also enhance lateral root growth, resulting in a significant increase in overall root mass and surface area.

    The obvious benefits of this are increased water use efficiency and nutrient uptake, a more resilient plant in drought conditions and a well-anchored plant in wind or storm conditions. As the roots develop they also interact with the microbes found in surrounding soil that enable the free movement of minerals and nutrients into the root system. This has been scientifically proven in more than 600 field trials over the past 40 years.

  • Nutrient and Water Uptake

    Through improved root development and vascular tissue growth, water, nutrients, sugar molecules, amino acids and hormones can be transported through the plant more efficiently, ensuring the crop remains hydrated and nourished, ultimately ensuring an improved crop yield.

    This also ensures that the crop benefits fully from your usual fertiliser program, as more nutrients are taken up by the roots and absorbed by the plant more efficiently.

  • Plant Development

    Plant cell division and leaf spread are improved, ensuring higher chlorophyll production resulting in a healthier plant.

  • Pollen Tube Development

    Recent scientic studies clearly indicate the dramatic effect Kelpak has on pollen grain germination and pollen tube elongation. The pollen grain germinates and the pollen tube develops much faster when treated with Kelpak. This ultimately results in improved fruit set and crop yield.

  • Fruit Set

    The number of fruits per tree is improved as the overall percentage of fertilised flowers is significantly increased, ensuring improved fruit set and healthy fruit development. Kelpak application also ensures a higher rate of fruit set in cold or drought conditions. These adverse conditions negatively affect fruit set and Kelpak application can help offset this.

  • Fruit and Berry Size

    Kelpak helps in the development of the plant's root system and its vascular tissue which ultimately benefits fruit size through the provision of nutrients, minerals and essential compounds throughout the plant. Global trials and research indicate that the numerous natural bioactive compounds in Kelpak aid the plant's endogenous biosynthetic pathways that then lead to increased fruit sizing and uniformity.

  • Fruit Colour

    Fruit colour is an essential aspect of determining crop value. The active elements in Kelpak indirectly assist the plant's natural physiological processes, ensuring excellent fruit colour.

  • Fruit Quality

    Kelpak application improves firmness, shelf life and colour. By maintaining optimal nutrition and moisture levels in the plant before harvest, Kelpak application ensures that the fruit remains firm for longer periods on the shelf. Sugar levels are also improved as the additional nutrients deposit more starch which in turn is converted to sugars during ripening.

  • Resistance to Abiotic Stresses

    Kelpak provides a healthy root system, stronger stems and foliar growth, ensuring your plant will be more tolerant to abiotic stresses.

    Kelpak application directly after a crop has experienced stress such as drought, frost, hail or flooding, also benefits the plant's recovery.

    After transplant and harvest, most crops will experience shock. Kelpak application before or after these events will significantly improve re-establishment and ensure healthy reserves during dormancy.

  • Prevents Leaf Burn

    While calcium application is important in apple production, it often results in leaf scorch which will affect tree health and productivity. Kelpak acts as a buffer when applied together with calcium sprays, reducing leaf burn from these applications.

  • Excellent Returns on Investment

    Over four decades of trials consistently show that the return on investment when using Kelpak is significant, the extra value added to yield and quality of the crop far outweighing the cost.

    While the farmer has to consider every additional expense incurred in order to remain profitable, the added security provided when using Kelpak not only means that his crop will survive, but it will flourish, providing that much needed profit.
