Product Information
- Product Name: Seaweed Extract 12%
- Description: A natural liquid biostimulant and organic fertilizer derived from marine brown algae (primarily Ascophyllum nodosum or similar species, such as kelp and brown algae). This product is a concentrated extract containing 12% seaweed solids (w/v), rich in natural plant growth regulators, alginic acid, trace elements, and organic matter. It serves as a plant growth enhancer rather than a primary NPK fertilizer.
- Form: Dark brown to black liquid
- Odor: Characteristic mild seaweed scent
- Source: Extracted from fresh or dried marine algae via physical or low-temperature processes to preserve bioactive compounds.

Benefits and Functions
- Enhances seed germination, root development, and overall plant vigor.
- Improves nutrient uptake efficiency and soil structure through alginic acid.
- Increases resistance to abiotic stresses (drought, salinity) and biotic stresses (pests, diseases).
- Promotes flowering, fruit set, and quality improvement (e.g., size, color, shelf life).
- Biodegradable and environmentally friendly; suitable for organic farming.
- Compatible with most fertilizers, insecticides, and fungicides.
Recommended Application
- Methods: Foliar spray, soil drench, or fertigation (drip irrigation).
- Dilution Rates:
- Foliar: 1:1000–1:2000 (0.5–1 ml/L water).
- Soil/Root: 1:500–1:1000.
- Seed Treatment: Soak in 1:1000 dilution.
- Dosage: 1–2 L/ha per application; apply 2–4 times during growth cycle (vegetative, flowering, fruiting stages).
- Frequency: Every 10–15 days; adjust based on crop needs.
- Crops: Suitable for vegetables, fruits, field crops, ornamentals, and turf.
Storage and Handling
