Product Description

Seaweed extract Green contains 40% seaweed oligosaccharides and 18% K2O, making it a powerful addition to any plant growing regimen. Seaweed Extract Green uses Ascophyllum nodosum, a brown alga that grows in the cold waters of the Atlantic coast.

It is a valuable source of trace minerals and micronutrients that promote plant growth and resilience. The beneficial carbohydrates in Green Seaweed Extract activate the plant's natural defense mechanisms, making the plant healthier and able to withstand environmental stressors. Potassium (K2O) inside of the material is essential for proper plant development, including strong stems and roots. It also enhances the uptake of water and nutrients into the soil, resulting in increased flower and fruit production and higher overall yields.

It is a versatile and user-friendly product. It can be easily mixed with water for foliar spraying or incorporated into the soil during planting or transplanting. Works on a wide variety of plants, including ornamentals, fruits, vegetables, and herbs. Use green seaweed extract to promote healthy plant growth and increase yield. Its rich mineral content and active carbohydrates synergistically support the development of strong stems and roots.


1. Promote the growth and development of plants: The plant growth regulating substances rich in seaweed, such as auxin and gibberellin, can stimulate the growth and development of plants, promote the elongation of young leaves, and accelerate the formation and growth of flowers and fruits.

2. Enhance the resistance of plants: polysaccharides, proteins and other components in seaweed can promote the vitality of the plant immune system and improve the resistance of plants to adverse environments.

3. Improve soil: Seaweed fertilizer can improve soil structure, increase soil air permeability and water retention, and increase the number of soil microorganisms.

4. Promote nutrient absorption: organic substances such as calcium gluconate and iron gluconate rich in seaweed fertilizer can promote the absorption and utilization of nutrients by plants, and improve the quality and yield of crops.

Seaweed extract green powder is a kind of seaweed Oligosaccharide, which contains more than 70 minerals, vitamins and enzymes.  it is a kind of high-level products that contains a variety of natural plant growth regulators, such as highly unsaturated fatty acids, potassium, phosphorus, calcium, magnesium, zinc, iodine and other more than 40 minerals and rich vitamins, is unmatched by land plants.

1. Stimulate the activity of defense enzyme system in plants and induced resistance of crops to produce a variety of substances, enhance crop drought resistance, cold resistance, resistance to salt, acid and alkali resistance ability, can inhibit the virus, bacteria, fog, soft rot bacteria, damping bacteria, such as root rot fungus can promote nitrogen-fixing bacteria, cellulose decomposing bacteria, lactic acid bacteria, actinomyces and bacteria proliferation and increase the number of actinomycetes nearly 30 times. At the same time can effectively improve the soil, improve the living environment of crops.

2. Balanced regulation of plant growth, promote flower bud differentiation, improve fruit set rate, control tree without fruit, dark green leaf color after spraying, thick stem, disease resistance and high yield, early flowering, multiple fruits, large fruits, single fruit weight, early market, good fruit color, reduce fruit falling and cracking.

3. Promote the development of plant roots, improve the absorption and utilization of soil nutrients and water, increase the content of chlorophyll, improve the efficiency of photosynthesis, greatly increase the yield and improve the quality.

4. In the first year, the incidence can be reduced by 40%, and the yield can be increased by 45%. In the second year, the incidence was reduced by 60%, the yield was increased by 32%, and the soil microbial area was significantly increased.

5. Please ensure that the soil moisture and fertilizer are sufficient when using this product.

This product is a natural biological agent, harmless and POLLUTION-free, can effectively protect the environment, maintain ecological balance, is the production of pollution-free agricultural products of excellent preparation.

It can promote additional budding if applied as the plants are beginning to bud and extends the shelf life of fruits and vegetables if applied 10 days before harvesting. The extract lengthens the life of cut flowers if they are sprayed with it a day or two before cutting. It can also be used as a rooting solution.

Seaweed extract also boosts crop yields, improves resistance of plants to frost and disease, increases uptake of inorganic constituents from the soil, bolsters resistance to stress conditions and reduces storage losses of fruit. It promotes vigorous growth and helps deter pests and diseases on fruit, flowers, vegetables, lawns etc. it is especially useful in organic gardening. They contain almost every micro-nutrient in a fully chelated (immediately available) form. The algae are also full of carbohydrates, which plants use as a building block. Numerous beneficial microorganisms also use carbohydrates as a food source.

There are very important Plant Hormones naturally found in Seaweed. Nature hormones, in which the most important ones are auxins, cytokinin, betaines and Gebelein's. These hormones are essential for plant health. Most of them only require a very small percentage but are still important.

There are many different kinds of auxins, all of which have specific roles. One of the most important functions is to balance the growth rate. stimulating growth. also stimulating root growth and preventing shoots from forming or opening at the wrong time. Seaweed contains natural auxins that play an important role in the production of plants' own auxins. Because enzymes formed with the help of trace elements in seaweed fertilizers play an important role in the formation of these auxins.


Cytokinin are another group of important plant hormones. They start and activate the basic growth process. The cytokinin in seaweed extract stimulate growth with greater vigor as they mobilize nutrients in the leaves. They also provide protection from edge frost (up to -3 degrees Celsius). Cytokinin also slow down the senescence (aging process) of plants.


Betaine plays a crucial role in the osmotic process of plants. They help increase water uptake by the plant and are very helpful in dry conditions. Betaine is also particularly helpful for plants that are under stress.

Frequently Asked Question

1. From properties, it seems seaweed oligosaccharides is similar with seaweed alginic acid, but contents much higher, why?
The seaweed extract(oligosaccharides) is the up graded product of seaweed alginic acid. By special secondary low-temperature directional enzymatic hydrolysis technology, membrane filtration and natural anti-corrosion technology, small molecule active oligosaccharides (≤2000Da) can be got, that are easier to be absorbed by plant.
