Why seaweed
Seaweed has become an essential part of the fertiliser industry, valued for its natural ability to improve soil health and promote plant growth.
Rich in nitrogen, potassium, magnesium and calcium, seaweed acts as a biostimulant, improving soil fertility and plant resilience. Alginates, polyphenols and natural plant hormones like auxins and cytokinins encourage root development, improve water retention and boost plant immunity. Seaweed fertilisers are biodegradable and eco-friendly, a sustainable alternative to synthetics.
A full range of seaweed species, all sustainably harvested and organically handled. Supplied wholeleaf, milled or as micron powder.
Benefits
What seaweed brings
Soil health
Adds nutrients and organic matter, with Ascophyllum nodosum and Fucus vesiculosus, and boosts microbial activity for a healthier soil ecosystem.
Plant growth
Natural plant hormones in Ascophyllum nodosum and Himanthalia elongata encourage roots, while Laminaria digitata and Alaria esculenta lift growth and yield.
Water retention
Improves soil structure to hold water and reduce irrigation, with Ulva lactuca and Saccharina latissima.
Pest & disease resistance
Boosts plant immunity and reduces reliance on chemical pesticides, aided by Fucus vesiculosus and Ascophyllum nodosum.
Sustainability
Biodegradable and lower-impact than synthetic fertilisers, led by Laminaria digitata and Himanthalia elongata.
Versatile application
Suitable for liquid fertilisers, foliar sprays and soil conditioners, using Alaria esculenta and Ulva lactuca.
