Scope of Application
This product is suitable for various field crops, fruits, vegetables, tobacco, tea plants, flowers, nurseries, lawns, medicinal herbs, landscaping, and other cash crops.
Application Guidelines
Drip Irrigation (Recommended)
High-concentration liquid fertilizer suitable for facility agriculture and precision fertilization; seaweed extracts can be directly absorbed and utilized by crops.
- Concentration: Dilute 300–500 times
- Application Rate: 5–10 L/mu per application
- Frequency: Once every 10–15 days
- Note: Can be used in combination with water-soluble macro-element fertilizers.
Fertigation
Apply via fertigation with watering, suitable for supplementing nutrition in cash crops such as fruit trees and vegetables.
- Dosage: 10–20 L/mu per application
- Dilution Ratio: 1:100 — 1:200
- Time: Critical Crop Growth Period
- Note: Better results with frequent small applications
Foliar Spray
Rapidly supplements nutrition and corrects nutrient deficiency symptoms, especially suitable for use during fruit development.
- Dilution Ratio: 1:500 — 1:800
- Application Rate: 30–60 L/mu
- Time: Morning or evening, avoid high temperatures
- Note: Pay attention to concentration when used with other foliar fertilizers
Water-Soluble Fertilizer Blending
Use as an organic nutrient source in combination with water-soluble macro-element fertilizers to achieve balanced nutrition.
- Use in combination with water-soluble macronutrient fertilizers
- Addition ratio: 10–20%
- Suitable for melons, fruits, vegetables, and fruit trees
- Increases fertilizer efficiency and reduces soil acidification

| Field Crops | Wheat, Corn, Rice, Cotton | 5 — 8 L/acre | 10 — 15 L/mu | Seedling Stage, Growth Stage, Grain Filling Stage |
| Fruit Trees | Apple, pear, peach, grape, citrus | 8 — 12 L/mu | 15 — 20 L/mu | Germination stage, flowering stage, fruit expansion stage |
| Vegetables | Tomato, cucumber, pepper, eggplant | 5 — 8 L/acre | 10 — 15 L/mu | Seedling Stage, Flowering Stage, Fruiting Stage |
| Melons and Fruits | Watermelons, Melons, Strawberries | 5 — 8 L/acre | 10 — 15 L/mu | Vine extension, flowering, and fruit expansion stages |
| Cash Crops | Tobacco, Tea Plants, Flowers | 5 — 10 L/mu | 10 — 15 L/mu | During Growth Period, After Harvest |
- Store in a cool, dry place away from direct sunlight.
- Shake well before use. Sedimentation is normal and does not affect fertilizer efficacy.
- It can be mixed with most fertilizers and pesticides, but a small-scale trial before use is recommended.
- For foliar application, it is recommended to conduct a small-scale trial first to confirm no phytotoxicity before large-scale use.
- Before using drip irrigation, it is recommended to filter the solution to prevent impurities from clogging the drippers.
Frequently Asked Questions
The main differences lie in nutrient form and added value:
- General Purpose Water-Soluble NPK FertilizerProvides only inorganic nutrients such as nitrogen, phosphorus, and potassium, with a single nutritional profile.
- Seaweed Liquid FertilizerIn addition to providing macro-elements (NPK 7-12-15), it is supplemented with seaweed polysaccharides ≥20g/L and organic matter ≥100g/L, offering crops rich organic nutrition and natural bioactive substances.
- Comprehensive Adjustment FunctionNatural plant growth regulators in seaweed extracts comprehensively regulate various physiological functions of crops, improve stress resistance, and enhance quality.
Low-temperature decomposition technology is an advanced seaweed processing method:
- Preserve Active IngredientsDecomposition is carried out under low-temperature conditions to maximally preserve natural active substances in seaweed, such as seaweed polysaccharides and plant growth regulators.
- Natural Product AppearancePresents the original light green appearance of seaweed, dark green liquid, pure color.
- Nutritional IntegrityAvoids the destruction of nutrients by high-temperature processing, resulting in more comprehensive and sufficient product nutrition.
- High Absorption and Utilization RateLow-temperature decomposition products are more easily absorbed and utilized by crops, improving fertilizer efficiency.
Based on the crop growth cycle and fertilizer requirements:
- Seedling StagePromotes seedling growth, enhances photosynthesis, laying a foundation for later growth.
- Growth PeriodSupplies macronutrients to promote vegetative growth and enhance crop vigor.
- Flowering and Fruiting StageHigh phosphorus and potassium content, promotes flower bud differentiation, increases fruit setting rate, and promotes fruit enlargement.
- Fruit Enlargement StageHigh-potassium formula promotes rapid fruit expansion and improves fruit quality.
For optimal results, it is recommended to apply continuously during the critical nutrient-demand periods of the crop.
