Seaweed extract 12% is primarily kelp and other brown algae. These are processed through physical crushing, biochemical extraction, concentration via absorption, and film drying, resulting in a final product available as flakes or powder.
This seaweed extract offers distinct characteristics, including rapid dissolution, high biological activity, and excellent absorption by plants. It supports several key functions, such as promoting plant growth, increasing crop yields, helping prevent diseases, and repelling certain insects.
It can be applied through various methods, including root irrigation, fertigation (water flushing), and foliar spraying. Additionally, it serves as a valuable ingredient in the production of biological fertilizers, compound fertilizers, and organic fertilizers.
Higher-concentration variants are also available, including those with 14%-16%, 18%, and 20% active content (typically referring to alginic acid or equivalent key components).

12% Seaweed Extract – Primary Functions
The 12% seaweed extract delivers the following principal benefits to crops:
- It promotes seed germination and increases the germination percentage.
- It enhances root system development, enabling plants to absorb water and nutrients more effectively.
- It activates NPK nutrients and trace elements, counteracting phosphate fixation in the soil and thereby improving the availability and uptake of micronutrients.
- It elevates the activity of multiple enzymes in the plant, strengthening metabolic processes and supporting more vigorous and uniform growth.
- It stimulates flower bud differentiation, improves fruit set, promotes fruit enlargement, enhances fruit coloration, and accelerates maturity.
- It increases the plant’s tolerance to abiotic and biotic stresses, including drought, low temperatures, pests, and diseases.
- It contributes to higher crop yields and superior quality of harvested produce.
Recommended Application Methods
- Dilute the product at a ratio of 1:1000 (1 part extract to 1000 parts water) for use in fertigation (drip or flushing irrigation) and foliar spraying.
- Blend with compound fertilizers at a ratio of 1:100 (1 part seaweed extract to 100 parts fertilizer) to enhance nutrient performance.
- To improve the efficacy of pesticides or foliar fertilizers, incorporate the seaweed extract into the spray solution at a ratio of 1:5000.
This product, supplied as black flakes or powder, is completely water-soluble and derived from brown seaweed. Its effectiveness is primarily attributed to the presence of alginic acid (≥12%), seaweed polysaccharides, mannitol, amino acids, and other bioactive components.
