The primary raw materials for this seaweed extract 18% are kelp and other brown algae. The extract is produced through specialized biochemical processes that carefully preserve the seaweed’s natural active components.
This results in a product rich in non-nitrogenous organic compounds, more than 40 mineral elements, and a variety of vitamins—including potassium, calcium, magnesium, zinc, and iodine—at levels far higher than those found in most land plants.
The extract contains significant amounts of seaweed polysaccharides, alginic acid, highly unsaturated fatty acids, and various natural plant growth regulators. These substances exhibit strong biological activity, enabling them to stimulate the production of non-specific defense factors in plants and help regulate the balance of endogenous hormones.
Available concentrations
Other variants of seaweed extract are available at 12%, 14%–16%, and 20% (typically referring to alginic acid or equivalent key active content).

Main Functions
This 18% seaweed extract provides the following primary benefits:
- Soil improvement: It swells upon water absorption, helps loosen compacted soil, breaks up surface crusts, and helps prevent soil degradation such as acidification and salinization.
- Environmentally friendly effects: It regulates soil microbial ecology, helps reduce pesticide residues in the soil, and contributes to the passivation of heavy metals.
- Disease reduction: It suppresses the growth of soil-borne pathogens and helps lower populations of underground pests.
- Stress resistance enhancement: It supports the development of a strong root system, helps prevent excessive vegetative growth, induces the production of phytoalexins in plants, and increases overall crop tolerance to adverse conditions.
- Comprehensive nutrition supply: It supplies a broad range of medium and trace elements, effectively preventing deficiency symptoms in crops.
- Quality improvement: It enhances fruit coloration, improves surface gloss and hardness, increases the content of soluble solids, and improves storage stability of the produce.
- Yield increase: It promotes flower bud differentiation, raises fruit-setting rates, supports fruit enlargement, increases individual fruit weight, and advances crop maturity.
Recommended Usage
- Dilute the product with water at a ratio of 1:2500 to 1:3000 (1 part extract to 2500–3000 parts water) for applications through fertigation (flushing or drip irrigation) and foliar spraying.
- Combine with compound fertilizers at a ratio of 1:100 (1 part seaweed extract to 100 parts fertilizer).
- To boost the performance of pesticides or foliar fertilizers, add the seaweed extract to the spray solution at a ratio of 1:5000.
