Properties and effects of biostimulants based on seaweed extracts

Seaweed fertilizer refers to the use of macroalgae growing in the ocean as raw materials, mostly cold-water waters of the brown algae of the algae-based, through a special physiological and biochemical process, the inside of the beneficial substances extracted, applied to agricultural production, plant growth for the growth of fertilizers to provide favorable help. Due to the special environment of seaweed growth, it is of great help to agricultural production, which makes the application prospect of seaweed fertilizer more and more broad. Therefore, there are more and more kinds of seaweed fertilizers on the market, and the scope of application is also more and more extensive.

3.the mechanism of seaweed extract:

●To promote the growth of soil microorganisms, enrich the microbial flora, and then improve the physical and chemical properties of the soil to promote plant growth.

●Contains plant growth regulators to directly stimulate plant growth and development, seaweed extract contains a variety of plant hormones, and seaweed extract contains a variety of plant growth regulators (cytokinin, growth hormone, abscisic acid, gibberellin), so you need to pay attention to the amount of seaweed.

●Improve soil structure, such as seaweed acid chelated into alginate with gel properties, promote soil aggregate structure and humus formation.
