The seaweed extract powder we use primarily originates from Ascophyllum nodosum, imported from Canada. Using advanced biological enzymatic processes, our production technology ensures top-tier quality. The compounds of our seaweed extract powder fertilizer include cytokinin, oligomeric alginate potassium, betaine, mannitol, polysaccharides, iodine, trace elements, and alginic polyphenols, all obtained from sea-grown seaweed through biochemical techniques.
The diverse features of this soluble seaweed extract powder make it essential in promoting cell proliferation, improving resilience against stress, fortifying defences against diseases and pests, enhancing crop yield, and moderating growth. Also, it aids in improving the soil's quality. Our brown seaweed extract powder ensures the production of green organic food, owing to its optimal performance and safety standards.


1:Pure seaweed extract promotes the growth of roots, resolves issues linked to successive cropping, enhances the efficiency of fertilizer application, and decelerates the aging process of plants.
2:It oversees and balances the plant's growth, curtails excess branch development, and minimizes pruning.3:The extract aids in the growth of leaves and the process of photosynthesis, which is essential for nutrient accumulation, transfer, and retention.
4:Alginate sodium, an element in the seaweed extract, can increase bud and flower production and lower the incidence of abnormal, undersized, and rotten fruits.
5:It ensures fruits maintain a healthy form, vibrant and colorful skin, high sugar levels, and offers long-term storage.
6:Our seaweed extract fertilizer can improve symptoms such as undersized leaves, yellowing leaves, shriveling fruits, bitter pits, and other physiological diseases caused by nutrient deficiency.
7:It works as a deterrent for insects and slows the spread of diseases transmitted by worms, phytoplasmas, and bacteria.
8:The extract boosts the plant's ability to withstand drought, cold, diseases, and floods.
9:The extract helps adjust the pH of the soil, ameliorate soil physical structure, conserve moisture and fertility, fostering the growth of microorganisms.
