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 5 combines our trusted seaweed extract with a higher dose of nutrition, delivering 5 kg of NPK per 100 litres to support early crop growth and ongoing plant development.
As with all our SeaFol products, SeaFol Complex 5 is a pure, concentrated seaweed extract rich in natural growth stimulants, phytohormones, and trace elements that work together to build strong, resilient crops.
Our extraction process is chemical-free, ensuring that the natural bioactive compounds are preserved for maximum benefit to the crop. SeaFol Complex 5 is acidic, which helps improve tank mix compatibility by enhancing the solubility of other products.
The key benefits of SeaFol Complex 5 in crop production are:
Vigorous root development to access soil nutrients and moisture
Greener, more efficient leaves with higher chlorophyll levels
Greater resilience to stress caused by cold, drought, or nutrient deficiency
A substantial nutrient boost from added NPK to promote strong early growth
Improved soil biology through enhanced microbial activity
Uniform, healthy crop development
Increased potential yield
Naturally high in laminarin, which has been known to supress Septoria and Powdery Mildew
SeaFol Complex 5 is suitable for use in conventional systems and may also be used in organic production where permitted.
Apply SeaFol Complex 5 early in the crop cycle to support strong establishment and again in spring to encourage vigorous growth. Recommended for winter-sown crops at a rate of 2 litres per hectare in autumn, followed by 2 litres per hectare in spring. Always dilute in water and apply as a foliar spray or soil drench. Ensure full dispersion before application and agitate if necessary. Clean out spraying equipment thoroughly 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 5 delivers the combined benefits of seaweed-based biostimulation and an enhanced nutritional package. As a biofertiliser, it supplies 5 kg of NPK per 100 litres along with trace elements and organic carbon to support vigorous early growth. As a biostimulant, it promotes physiological responses beyond those expected from nutrients alone—including improved root development, greater tolerance to abiotic stress, and enhanced overall plant vitality. The increased nutrient load makes it ideal for pushing crops forward during key stages of establishment and recovery, contributing to stronger growth and improved yield potential.
CroptekBio products are used across a wide range of market sectors, whether you’re looking to improve yields, or improving soil and turf growth we can help.
