Product description
Product overview
Granular seaweed fertilizer is a highly effective organic granular fertilizer produced from high-quality seaweed extract. The product is black granules, available in two types: Type I - organic granular seaweed fertilizer, suitable for conventional base fertilizer application; Type II - water-soluble granular seaweed fertilizer, water-insoluble content ≤5%, can be used in drip irrigation systems.
Product Features
- High organic matter contentOrganic matter ≥60%, improves soil structure, enhances its water-holding and nutrient-holding capacity.
- High seaweed extract contentSeaweed extract ≥30%, rich in natural plant growth substances.
- Available in Two VariantsType I is suitable for regular base fertilizer; Type II can be used in drip irrigation systems.
- Granular formConvenient for mechanical application, uniform spreading
- Long-Lasting Fertilizer EffectUsed as a base fertilizer, providing continuous nutrition to crops.
- Eco-friendlyOrganic raw materials, no chemical additives, environmentally safe.
Key action
Soil improvement
Rich organic matter improves soil aggregate structure, enhancing soil aeration, water retention, and nutrient holding capacity.
Growth stimulation
Natural biostimulants in seaweed extract promote plant root system development and nutrient absorption.
Stress Resistance Enhancement
Enhances crop resistance to drought, salinity, diseases, and other stress factors.
Quality improvement
Improves appearance and taste of agricultural products, enhances market value.
Area of application
Application Recommendations
In-furrow Application (Recommended)
Granular fertilizer applied to planting holes or pits for fruit trees as a base fertilizer for crop nutrition.
- Application Rate per Mu: 40-80 kg/Mu
- Application timing: before sowing or transplanting
- Application method: uniform mixing with soil
- Attention: after application, incorporate into soil and water
Band Application
Apply in furrows along planting rows, suitable for mechanized treatment of large areas.
- Application Rate per Mu: 40-80 kg/Mu
- Application timing: before seeding or during soil cultivation
- Application method: furrow depth 15-20 cm.
- Attention: after application, incorporate into soil and water
Area of application
| Crop Type | Typical crops | Recommended dosage |
|---|---|---|
| Industrial crops | Flowers, tea, tobacco | 80 kg/mu |
| Vegetables | Tomatoes, cucumbers, peppers, leafy greens | 80 kg/mu |
| Melons and gourds | Watermelon, melon, strawberry | 80 kg/mu |
| Cereals, cotton, and oilseed crops | Rice, wheat, corn, cotton, rapeseed | 80 kg/mu |
| Field Crops | Various field crops | 80 kg/mu |
| High-yield industrial crops | Fruit trees, vegetable and fruit greenhouses | Increase dose if necessary |
- Suitable for use as a base fertilizer, can be applied in holes or furrows.
- Application rate: 40-80 kg/mu; for high-yield cash crops, the dose can be increased as needed.
- Store in a cool, dry place, avoid direct sunlight and humid conditions.
- After application, immediately incorporate into the soil and water to accelerate fertilizer dissolution and crop uptake.
- Can be used together with organic and mineral fertilizers for better effect.
Frequently asked questions
Main differences between the two types:
- Type I (Granulated organic seaweed fertilizer)Suitable for conventional base fertilization, can be applied locally in holes or rows, suitable for various crops.
- Type II (Granulated Water-Soluble Seaweed Fertilizer)Water-insoluble residue ≤5%, suitable not only for base application but also for drip irrigation, offering a wider range of applications.
Recommendation: if only for base fertilizer, Type I is sufficient; if also needed for drip irrigation, choose Type II.
Key differences:
- Raw MaterialsGranular seaweed fertilizer is made from seaweed extract, while conventional organic fertilizers are made from manure, poultry litter, plant residues, etc.
- NutrientsGranular seaweed fertilizer contains seaweed-specific active substances such as alginates, mannitol, and auxins, while conventional organic fertilizers have a relatively uniform nutrient composition.
- EfficiencyGranulated seaweed fertilizer, besides improving soil, also promotes plant growth and enhances stress tolerance.
- Organic Matter ContentOrganic matter content in granular seaweed fertilizer ≥60%, exceeding standards for conventional organic fertilizers.
Total recommended application rate is 40-80 kg/mu; the specific dosage should be determined based on the following factors:
- Crop TypeFor high-yield cash crops (e.g., fruit trees, greenhouse vegetables), the dosage can be increased accordingly.
- Soil conditionsOn poor or newly cultivated soils, the dose should be increased.
- Planting DensityFor dense crops, increase the dose.
- Crop rotationUnder long-term monoculture farming, the dosage should be increased.
For first-time use, it is recommended to consult a specialist or conduct small-area tests to determine the optimal rate.
