Product Name: Seaweed Extract Fertilizer 14%-16%
Description: A natural liquid biostimulant and organic fertilizer derived from marine brown algae (primarily Ascophyllum nodosum or similar species such as kelp and other brown algae). This product is a concentrated extract containing 14%-16% seaweed solids (w/v), enriched with natural plant growth regulators, alginic acid, trace elements, and organic matter. It functions primarily as a plant growth enhancer and soil conditioner 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 using low-temperature or enzymatic processes to preserve bioactive compounds.

Benefits and Functions
- Promotes enhanced seed germination, robust root development, and improved plant vigor.
- Facilitates better nutrient uptake and soil structure improvement via alginic acid.
- Enhances tolerance to abiotic stresses (e.g., drought, salinity) and biotic stresses (e.g., pests, diseases).
- Supports increased flowering, fruit set, and overall crop quality (e.g., size, color, shelf life).
- Fully biodegradable and environmentally compatible; ideal for organic and sustainable farming practices.
- 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: 1.5–3 L/ha per application; apply 2–4 times during the growth cycle (vegetative, flowering, and fruiting stages).
- Frequency: Every 10–15 days; adjust according to crop requirements and environmental conditions.
- Crops: Suitable for vegetables, fruits, field crops, ornamentals, turf, and greenhouse productions.
Storage and Handling
- Store in a cool, dry location protected from direct sunlight.
- Shelf Life: 2–3 years when stored under recommended conditions.
- Precautions: Non-toxic; avoid contact with eyes. Rinse thoroughly with water if contact occurs. Employ protective equipment during handling.
Safety and Environmental Notes
- Classified as non-hazardous; fully biodegradable with negligible environmental impact.
