Seaweed extracts from Ascophyllum nodosum have repeatedly shown their ability to promote yield and plant health in both scientific and on-farm trials. These seaweed extracts are well established as a biofertiliser and as a plant biostimulant.
SeaFol Complex 2 builds on the proven benefits of our original seaweed extract, with the added advantage of 2 kg of NPK (Nitrogen, Phosphorus and Potassium) per 100 litres, offering an integrated nutrient boost alongside natural growth stimulation.
Like SeaFol, SeaFol Complex 2 is a pure concentrated seaweed extract containing natural plant growth stimulants, phytohormones and a range of trace elements which promote strong, healthy crops.
Our extraction method uses no chemicals, preserving the full range of naturally occurring active ingredients for crop uptake. SeaFol Complex 2 is acidic, enhancing the solubility of other inputs when tank mixed.
The key benefits of SeaFol Complex 2 in crop production are:
Improved root development for better access to water and nutrients
Greener leaves with higher chlorophyll content to support photosynthesis
Increased tolerance to abiotic stress such as drought or temperature extremes
A nutrient boost from added NPK for early vigour and spring recovery
Enhanced soil microbial activity supporting overall soil health
Stronger, more resilient crop growth
Increased yield potential
High levels of laminarin which can contribute to then suppression of Septoria and Powdery Mildew in winter wheat and other crops
SeaFol Complex 2 is suitable for use in conventional production systems.
SeaFol Complex 2 should be applied early in the crop cycle to support establishment and again in spring to encourage renewed growth. Use on winter-sown crops at 2 litres per hectare in autumn and repeat at 2 litres per hectare in spring. Always dilute in water and apply as either a foliar spray or soil drench. Ensure the product is fully dispersed before application. Agitate if necessary. Flush sprayers or applicators after use. Do not store diluted product for more than three days.
We cannot predict or guarantee tank mix success for any product: always conduct a mix test to confirm compatibility.
SeaFol Complex 2 functions as both a biofertiliser and a biostimulant. As a biofertiliser, it provides a balanced supply of NPK nutrients (2 kg per 100 litres), trace elements, and organic carbon to support early crop growth. As a biostimulant, it triggers plant responses that go beyond basic nutrition—stimulating root development, enhancing stress tolerance, improving nutrient uptake, and supporting stronger establishment in autumn and spring applications. The seaweed extract base also promotes flower and fruit retention, contributing to increased yield and crop resilience.
