The raw materials for seaweed extract 20% are primarily kelp and other brown algae. These undergo processing steps such as physical crushing, biochemical extraction, concentration through absorption, and film drying, resulting in the final product in the form of flakes or powder.
This seaweed extract in flake or powder form offers several notable characteristics: it dissolves quickly in water, retains high biological activity, and demonstrates excellent absorption by plants. It supports various beneficial effects, including enhanced plant growth, increased crop yields, improved disease resistance, and reduced pest issues.
The 20% seaweed extract can be applied through methods such as root irrigation, fertigation (flush irrigation), and foliar spraying. It also serves effectively as a base material in the production of biological fertilizers, compound fertilizers, and organic fertilizers.
Additional variants of seaweed extract are available with concentrations of 12%, 14–16%, and 18%.

Main Functions
This product delivers the following benefits:
- Provides organic nitrogen and helps improve soil fertility.
- Increases the crop’s ability to resist stress and disease.
- Supports cell elongation and proper tissue development.
- Speeds up enzyme activity, metabolic processes, and lignin formation.
- Aids in the transport of carbohydrates and the metabolism of proteins.
- Stimulates stronger root growth and better root system development.
- Enhances pollen germination and supports pollen tube growth.
- Encourages flower bud formation; improves fruit shape retention, gives brighter and more attractive peel color, and raises sugar levels in the fruit.
- Boosts the plant’s tolerance to frost, cold temperatures, waterlogging, and drought conditions.
Usage Instructions
- Dilute with water at a ratio of 1:3000 to 1:4000 for use in flush irrigation, drip irrigation, or foliar spraying. (Flakes are usually more convenient for these methods.)
- Mix with compound fertilizer at a ratio of 1:100 to improve overall nutrient performance.
- Combine with pesticides or foliar fertilizers at a ratio of 1:5000 to increase their effectiveness. (Powder form dissolves more quickly and is generally preferred for this application.)
