P2O5%: 0.2 Ph: 7-11

seaweed extract is in powder or flakes or liquid form. It is 100% water soluble bio-organic ferilizer. It is widely used for crops, flowers, fruits etc. As the big manufacturer of seaweed extract in China, Shandong Jiejing Group Corporation developed series of seaweed bio-organic ferilizer with seaweed extract as main material based on our own formulation. 

Main nutrients

The main nutrients of seaweed extract are divided into two parts: mineral elements and life active substances. The mineral elements absorbed and enriched by seaweeds in the marine environment: there are mainly nitrogen, phosphorus, potassium macroelements and trace elements such as iron, boron, molybdenum, calcium, magnesium, iodine, cobalt, zinc, manganese, and copper. The life active substances in seaweed mainly include: alginic acid, seaweed polysaccharides and oligosaccharides, amino acids, phenolic polymer compounds, mannitol, betaine, natural plant growth regulators (such as cytokinins, gibberellins), etc.
Functional material composition

Amino acid

Amino acids are the basic components of protein. They can be used as nitrogen with a good absorption effect, and they can also directly participate in protein synthesis in plants. Since plant self-protection is mostly achieved through various protective enzymes (proteins), deep-water seaweeds grow in a harsh environment, and the content of protective proteins in seaweeds is much higher than other plants. Jingdian Seaweed Essential Amino Acids are extracted from deep-sea seaweeds, which can better increase the protein content of plants. It can not only improve the quality of agricultural products, but also improve the ability of crops to stay below the unfavorable environment.

Plant endogenous hormones

Plant endogenous hormones refer to hormones synthesized by plants themselves. Seaweeds grow fast. They are synthesized in some organs of the plant and then transferred to other plant organs, which can affect growth and differentiation. They play an important role in inhibiting cell growth, promoting organ maturation, and promoting plant growth and development. Phytohormones have important regulatory and control effects on plant growth and development. Seaweed grows fast, and the cell division speed is much higher than that of land plants, so the endogenous hormone levels in seaweed extracts are significantly better than land plants. The high-dose plant endogenous hormones in seaweed extract can well regulate the endogenous hormone levels of crops and ensure the production capacity.


The main effect of betaine is to increase cell osmotic pressure. In a high-salt and low-temperature environment, plant cells are prone to death due to a large amount of water loss; after the cell osmotic pressure is increased, the cell's water retention capacity is enhanced, and it can be more resistant to low-temperature and high-salt environments. Therefore, betaine can mainly improve the living ability of plants in low temperature, saline-alkali environments. In addition, betaine has a protective effect on the functional enzymes in plants, which can ensure the normal progress of plant life activities under harsh conditions. In addition, betaine also has a certain effect in repelling insects.


The main effect of mannitol is to participate in photosynthesis and enhance the ability of plant nutrient synthesis, which is of great significance for increasing production. After the photosynthesis efficiency is improved, the plant growth ability is strengthened, the plant content is increased, and the plant is indirectly improved. Mannitol can also quickly repair injured tissues of plants, speed up wound healing, unblock the blocked vascular bundles of plants, and has a certain effect on assisting diseases such as fusarium wilt.

Seaweed polysaccharides and oligosaccharides

Seaweed polysaccharides and oligosaccharides are high-content components in seaweed extracts. Polysaccharides are an important component of all living organisms, and play an important role in controlling cell division, regulating cell growth, and maintaining normal metabolism of living organisms. In addition, seaweed polysaccharides can be directly absorbed by plants as sugars to increase the sugar content of fruits and promote fruit coloring. Moreover, when plants encounter a harsh environment with insufficient energy synthesis of nutrients, the sugars can oxidize and release energy to maintain normal plant growth. Practice has shown that Aimeite has a more obvious effect on promoting plant growth and development when used in adverse environments such as low temperature and drought. Seaweed polysaccharide has a certain negative charge, and has a large surface area and electrical properties, so it has a good effect on middle and trace elements and a variety of biologically active substances, such as Ca (calcium), Mn (manganese), betaine, mannitol, etc. Strong chelating ability to ensure the overall absorption effect of seaweed essence.

Alginic acid

The content of alginic acid in seaweeds is relatively high, and it can play a similar role to silicone during use, improve the spreading ability of water on the surface of plants, and help the absorption quality under spray conditions. The application of alginic acid to the soil can also play a similar effect to fulvic acid, which can loosen the soil, improve the soil structure, and enhance the soil moisture and air permeability.

Jiejing is a leading enterprise with the longest history of the domestic seaweed integrated processing industry. It is the world's largest alginate manufacturer, Asia's largest manufacturer of seaweed active substances, and the only company in China that industrially extracts fucoidan, fucoxanthin, and brown algae polyphenols (BAP).

Product categories:
★ Alginic acid and its salts (sodium alginate, calcium, potassium, ammonium), alginic acid derivatives (propylene glycol alginate);
★ Marine biological active substances and marine drugs (fucoidan, fucoxanthin, alginate oligosaccharides, brown seaweed polyphenols);
★ Products and raw materials for the big health industry (seaweed concentrated powder, kelp polysaccharide extraction)
★ Seaweed bio-organic fertilizer and seaweed plant growth agent.
Today I mainly introduce Jiejing Seaweed bio-organic fertilizer and seaweed plant growth agent, because this year we focus on promoting this product to abroad. Jiejing seaweed extract powder fertilizer got highly appraised of farmers in China, and take big market share in Southern China. I believe the quality talks louder.
