Suitable crops and recommended dosage
| Crop Type | Typical crops | Drip irrigation rate | Application rate with irrigation | Application period |
|---|---|---|---|---|
| Field Crops | Wheat, Corn, Rice, Cotton | 5–8 L/ha | 10–15 L/mu | Seedling stage, vegetative stage, grain filling stage |
| Fruit Trees | Apple, pear, peach, grape, citrus | 8–12 L/ha | 15–20 L/mu | Germination, flowering, and fruit filling period. |
| Vegetables | Tomatoes, cucumbers, peppers, eggplants. | 5–8 L/ha | 10–15 L/mu | Seedling stage, flowering stage, fruiting stage |
| Melon and Gourd Crops | Watermelon, melon, strawberry | 5–8 L/ha | 10–15 L/mu | Period of vine growth, flowering, and fruit set. |
| Industrial crops | Tobacco, tea plants, flower crops | 5 – 10 L/mu | 10–15 L/mu | During growth period, after harvest |
- Store in a cool dry place, avoid direct sunlight.
- Shake well before use. The presence of sediment is normal and does not affect fertilizer efficacy.
- Can be mixed with most fertilizers and pesticides, but a preliminary test on a small area is recommended.
- For foliar spraying, it is recommended to first conduct a test on a small area and use on a large scale only after confirming no phytotoxicity.
- Before use in drip irrigation, it is recommended to filter the solution to prevent clogging of drippers with impurities.
Frequently asked questions
The main difference lies in nutrient form and added value:
- Conventional water-soluble fertilizer with macronutrientsSupplies only inorganic nutrients such as nitrogen, phosphorus, and potassium; nutrient composition is uniform.
- Liquid seaweed fertilizerIn addition to macronutrients (NPK 7-12-15), it is supplemented with seaweed polysaccharides ≥20 g/L and organic matter ≥100 g/L, providing crops with rich organic nutrition and natural bioactive substances.
- Integrated regulation functionNatural plant growth regulators contained in seaweed extract comprehensively regulate various physiological functions of crops, enhance their stress resistance, and improve quality.
Low-temperature decomposition technology is an advanced method for processing algae:
- Active Ingredient PreservationExtraction is carried out at low temperatures, which maximally preserves natural active substances from seaweed such as seaweed polysaccharides, plant growth regulators, and others.
- Natural appearance of the productMaintains natural light green color of algae, dark green liquid, pure color.
- Food IntegrityPrevents nutrient degradation during high-temperature processing; the product has a more complete and sufficient nutritional composition.
- High bioavailabilityProducts with low decomposition temperature are more easily absorbed by plants, increasing fertilizer use efficiency.
According to crop growth cycle and fertilizer consumption characteristics:
- Emergence PhasePromotes seedling growth, enhances photosynthesis, laying the foundation for subsequent growth
- Growth StageReplenishes macronutrients, stimulates vegetative growth, improves crop condition.
- Flowering and Fruiting PeriodHigh phosphorus and potassium content promotes flower bud differentiation, improves fruit set, and stimulates fruit enlargement.
- Fruit Filling PeriodHigh-potassium formula, promotes rapid fruit filling and improves fruit quality.
Sequential application is recommended during key crop nutrient demand periods for optimal effect.
Store in original packaging, sealed, in a cool, dry, well-ventilated place. Shelf Life:24 monthsStorage Precautions:
