Understanding Ascophyllum nodosum

Welcome to the world of Ascophyllum nodosum, affectionately known as rockweed, knotted wrack, knotted kelp or egg-wrack. Introduced to the Rainbow & Brown family in 2016, our Ascophyllum nodosum Seaweed Extract Flake is sourced from the icy waters of the Northern Hemisphere. This natural product has gained a loyal following, remaining a popular choice and a valuable complement for both agricultural and home use. Thriving in challenging intertidal environments, Ascophyllum nodosum has been the subject of extensive research for its agricultural benefits. Rich in over 70 minerals, 17 amino acids, 4 natural growth promoters, chelating agents and complex sugars, this type of seaweed species serves as a nutrient powerhouse that enriches both soil and plants. One of the key advantages of Ascophyllum nodosum lies in its ability to foster symbiotic relationships within the soil ecosystem. Plant roots, including those of pasture, exude substances that nourish soil microbes in the rhizosphere. In return, these microbes produce enzymes that aid in water and nutrient absorption, leading to enhanced crop yields, frost and disease resistance, nutrient uptake and overall plant vigour. Seaweed fertilisers such as our Seaweed Extract Flake are particularly beneficial in organic farming, providing a comprehensive array of micronutrients in a readily available form. Additionally, alginates found in seaweed act as superb soil conditioners, improving soil structure and water retention capacity. The remarkable resilience of Ascophyllum nodosum has established it as a top-tier seaweed and serves as an exceptional biostimulant.  

For an added boost, consider blending our Seaweed Extract with Gibber900 or Gibb-Gro gibberellic acid. Numerous success stories across the country have demonstrated that Gibber900 promotes accelerated growth and increased DM, while the Seaweed Extract enhances the lushness and vibrancy of Gibber-treated pastures.
