Seaweed liquid fertilizer (SLF) contains organic nutrients, like cytokinin, gibberellins and auxin. It also contains macro and micronutrients. Seaweed liquid fertilizer is made from kelp (brown algae), which contains alginate. This alginate reacts with metals in the soil and forms long, cross-linked polymers, which improve the crumbling of soil, swell up when they get wet. It retains moisture for a long time. They are especially useful in organic gardening, which provides carbohydrate for plants.
This manure has more than 70 minerals, vitamins and enzymes which promote vigorous growth in plants. The plants grown in seaweed liquid fertilizer have improved resistance to frost and disease, indicating that this fertilizer is ecofriendly-pesticide.
