Details about Seaweed Extract

New-Nutri Seaweed Extract is extracted from fresh kelp seaweed(algae), wild ascophyllum nodosum. It contains mineral nutrients, vitamins, both macro elements and micro nutrients, which enhance the plant growth. It can be applied as foliar spray or directly applied to the soil as an organic nutrition source and suitable for all crops and applications. Fertilizers derived from seaweeds are found to be superior to chemical fertilizers due to high level of organic matter, micro and macro elements, vitamins and fatty acids. Seaweed Extract can be used with or without chemical fertilizers. New-Nutri Seaweed Extract is certificated by OMRI for organic use in agriculture.

Advantages of New-Nutri Seaweed Extract

  1. OMRI listed for organic use
  2. Nutrient-Rich
    The seaweed extract fertilizer contains a large amount of organic matter, including 40 kinds of minerals such as potassium, calcium, magnesium, iron, zinc, and iodine, and abundant vitamins, which are unmatched by terrestrial plants, especially seaweed polysaccharides unique to seaweeds. Alginic acid, highly unsaturated fatty acids and a variety of natural plant growth regulators can stimulate the production of non-specific active factors in plants and regulate the balance of endogenous elements.
  3. Easily obsorbed by plants
    The active ingredients in seaweed extract fertilizers are particularly active after they have been specially treated, and they enter the plants within 2 to 3 hours after application, and they have a speedy absorption and conduction velocity. Alginic acid in seaweed extract fertilizer can reduce the surface tension of water, forming a layer of film on the surface of the plant, increasing the contact area, water-soluble substances are relatively easy to penetrate the surface cells of stems and leaves so that plants can effectively absorb the nutrients in the seaweed extract.
  4. Improve the soil
    New-Nutri Seaweed Extract is a natural biological system that works in harmony with the plant-soil ecosystem. It can directly increase soil organic matter through soil or plants and activate various microorganisms in the soil. These microorganisms can act as catalysts in the circulation of plant-microbial metabolites, increasing the biological effectiveness of the soil.
  5. Fertilizer effect long
    New-Nutri Seaweed Extract can directly increase soil organic matter through the soil or plants, and activate various beneficial microorganisms in the soil. These microorganisms can act as catalysts in the circulation of plant-microbial metabolites and increase the biological efficiency of the soil. Metabolites of plants and soil microorganisms can provide more nutrients to plants. At the same time, the chelation system formed by seaweed polysaccharides and humic acid can release nutrients slowly and extend fertilizer efficiency.
  6. Non-toxic and safe
    The seaweed extract fertilizer raw materials are derived from natural seaweeds, have good affinity with terrestrial plants, are non-toxic and harmless to humans and livestock, and have no pollution to the environment. They are high-quality fertilizers for the production of harmless vegetables.
