Seaweed extract fertilizer is the abbreviation of alginic acid-containing fertilizer. When the seaweed extract fertilizer is applied to the growth of plants, it has obvious benefits to the growth of plants. So what are the benefits of seaweed extract for plants? Today we are going to talk about this.

Seaweed is a low-level photosynthetic nutrient plant that grows in the ocean and is the original producer of marine organic matter. Since seaweed grows in seawater, it not only contains the nutrients of land plants, but also contains many incomparable trace elements from land plants, as well as seaweed polysaccharides, mannitol, etc.

seaweed extract benefits for plantsThe development of seaweed fertilizer has gone through three stages: rotten seaweed → seaweed ash (powder) → alginic acid (seaweed extract). The core substance in seaweed fertilizer is alginic acid (seaweed extract), and its main raw material is selected from natural seaweed.

After a special biochemical process treatment, the essence of seaweed is extracted, which greatly retains the natural active components. It contains a lot of mineral elements (potassium, calcium, magnesium, zinc, iodine, etc.) and rich vitamins.

And it especially contains the unique seaweed polysaccharides, alginic acid, highly unsaturated fatty acids and a variety of natural plant growth regulators. It has high biological activity and can stimulate the production of non-specific active factors in plants and regulate endogenous balance.

After special treatment, the effective components in seaweed are in an active state that is easily absorbed by plants. They enter the plant body within 2-3 hours after use, and have a fast absorption and transmission speed. Seaweed contains natural plant growth regulators such as auxins, cytokinins and gibberellins, which have high biological activity, and the proportions of various substances are similar to those in terrestrial plants.

seaweed extract benefits for plants

1.Increase the organic matter in the soil

Seaweed extract can directly increase soil organic matter or increase soil organic matter through plants. Various beneficial microorganisms in the soil can act as a catalyst in the cycle of plant and microbial metabolites, increasing the biological effectiveness of the soil. The metabolites of soil microorganisms can provide more nutrients for plants.

2.Improve soil structure

Seaweed extract is a natural biological agent that works in harmony with plant and soil ecosystems.

  • (1) It contains natural compounds such as sodium alginate, which are natural soil conditioners.
  • (2) Can promote the formation of soil aggregate structure,
  • (3) Improve the pore space in the soil, and coordinate the ratio of solid, liquid and gas in the soil.
  • (4) It can restore the natural colloid balance lost due to excessive soil burden and chemical pollution,
  • (5) Increase soil biological vitality, promote the release of nutrients, facilitate root growth, and improve crop resistance.

3.Better effect when combined with pesticides, chemical fertilizers, etc.

Seaweed extract can reduce the surface tension of water, form a film on the surface of the plant, increase the contact area, make it easier for water-soluble substances to enter the plant cell through the surface cell membrane of the stem and leaf, so that the plant can effectively absorb the nutrients in the seaweed extract.

Therefore, if the seaweed liquid fertilizer is mixed with insecticides, fungicides and chemical fertilizers, the effect will be better, the spraying cost can be reduced, and the pesticides and chemical fertilizers have a synergistic effect. It has been reported abroad that the seaweed extract contains natural antiviral effects.

The raw materials of seaweed fertilizer are selected from natural seaweeds, which have good compatibility with terrestrial plants, are harmless to humans and livestock, have no pollution to the environment, and have advantages that no other fertilizer can match.

seaweed extract benefits for plants

Seaweed extract fertilizer gathers a variety of active substances in the ocean, and has many advantages such as comprehensive nutrition, disease resistance, increased production, and no pollution. It is a good fertilizer that truly conforms to the development direction of modern agriculture. 

At present, new fertilizer products developed by seaweed have been widely used in developed countries and regions such as Europe and America, and are gradually replacing chemical fertilizers. Therefore, the prospect of seaweed extract fertilizer is very broad, and it is expected to become the dominant fertilizer in agriculture in the future.
