The Great Effect of Seaweed Extract on Agricultural Production

Seaweed contains a large number of bioactive components and nutrients that terrestrial organisms lack, which makes seaweed have great development and utilization value in the field of fertilizer application. Seaweed fertilizers are usually made from large brown algae that grow in the ocean, such as Ascophyllum nodosum, Sargassum, etc. Through chemical, physical and biological methods, the active ingredients in seaweed are extracted to make seaweed bio-organic fertilizer to provide nutrients for plant growth. The nutrients in seaweed fertilizer are rich and varied, including alginic acid, betaine, mannitol, cytokinin, amino acids, vitamins, minerals and other active substances with unique structures and seaweed metabolites. It contains organic active ingredients that integrate nutrients, antibiotics, and natural plant hormones. While providing sufficient nutrients for crop growth, the endogenous hormones contained in seaweed can significantly promote crop growth, increase yield, enhance crop stress resistance, reduce pests and diseases, optimize soil structure, and protect the ecological environment.

Seaweed extract is an important form of seaweed fertilizer. The preparation of seaweed extract is obtained by concentrating the degraded extract of seaweed. It usually has the form of powder, flakes and granules. The application method of seaweed extract is simple and diverse. When applying, it can be diluted with a certain proportion and then sprayed on leaves, irrigated roots or soaked in seeds. It can also be used as an additive raw material to make high-end foliar fertilizer and flushing fertilization. In addition, seaweed extract can also be added to NPK water-soluble fertilizers, organic water-soluble fertilizers, amino acid-containing humic acid water-soluble fertilizers, etc. By adding a small amount of seaweed extract, it can play a role in improving fertilizer efficiency. As a new functional fertilizer, seaweed extract has been widely recognized by agricultural workers for its beneficial effect on crop growth.
