Seaweed extract, available in the form of black powder or tablet (snowflake shape), is derived and refined from marine biological algae as the primary raw material.
It is rich in nutrients that plants can directly absorb and utilize. These include plant growth regulators (such as auxins, cytokinins, and gibberellins), alginic acid, humic acid, vitamins, nucleotides, plant stress resistance factors, and essential elements for plant growth—such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, molybdenum, and boron.
All bioactive components are natural substances extracted from seaweed. The product has no pungent chemical odor—only a mild, natural seaweed scent—and leaves no residue. Its appearance is black or brown powder, and it dissolves quickly in water.

Functions
Natural Ingredients
Made from natural seaweed as the main raw material, it is rich in seaweed polysaccharides, oligosaccharides, phenols, betaine, mannitol, and other natural active substances that meet the nutritional needs of crop growth.
Promotes Growth and Yield
Enhances root development, increases fruit-setting rate, promotes fruit expansion, improves coloring and early maturity, boosts crop quality, and increases yield. It is rich in proteins, amino acids, vitamins, and other active compounds, while also containing iodine, calcium, magnesium, phosphorus, potassium, and a variety of trace elements. With excellent antioxidant properties and biological activity, it helps delay crop aging and extends the harvest period.
Improves Resistance
Contains abundant antioxidant compounds and plant growth regulators that help regulate plant metabolism, enhance resistance to stress, and boost immunity in crops.
Reduces Pesticide Damage
Helps reduce pesticide damage and has a certain repair effect. It aids in the healing and recovery of damaged plants by promoting cell regeneration.
Foliar Spray: Diluted by 1: 1500-3000(5.4-7. 5kg/Ha), spraying at seedling stage, then every 10-15 days
Drip Irrigation/Water Flushing: 7. 5kg-15kg/Ha, can be used with other fertilizers Specific usage can be adjusted according to local soil fertility, crop growth andfertilizer level
Key Nutrients and Minerals in Seaweed Fertilizer
Seaweed fertilizers contain a wide array of essential plant nutrients and minerals that are vital for healthy growth. The key nutrients typically found are:
Nitrogen (N) – Seaweed has moderate levels of nitrogen, which is key for lush vegetative growth and green foliage. Nitrogen promotes leaf and stem growth.
Phosphorus (P) – Phosphorus encourages blooming, fruiting, and root development. It also helps with seed germination.
Potassium (K) – Potassium, or potash, increases disease resistance and drought tolerance. It produces sturdier plants.
Calcium – Calcium is essential for cell wall structure and fruit development. It prevents blossom end rot.
Magnesium – Magnesium aids in chlorophyll synthesis and activates vital plant enzymes.
Sulfur – Sulfur helps form amino acids, proteins, and vitamins. It promotes nodule formation.
Lron – Lron allows chlorophyll synthesis and is vital for photosynthesis. It prevents leaf chlorosis.
Zinc – Zinc is important for enzyme activation, seed formation, and internode elongation.
Manganese – Manganese catalyzes plant enzyme reactions and metabolism.
Storage
Store in a cool, dry place out of direct sunlight. High heat and humidity can degrade seaweed fertilizers over time.
Liquids should be stored above 40°F to prevent freezing and separation. Granular products are more stable.
Use containers that seal tightly. Open bags of granular fertilizer can absorb moisture and clump.
Handling
Wear gloves and wash hands after handling, as the salts may be drying to skin.
Avoid inhaling dust from granular fertilizers. A damp cloth can help contain dust.
Check for spills and clean equipment after mixing/loading liquids to avoid corrosion.
