Organic Seaweed Extract Fertilizer with Potassium Humate 98% Water Soluble Powder

ECER Organic Seaweed Extract Fertilizer with Potassium Humate is a premium organic biostimulant and soil conditioner crafted from wild-harvested Ascophyllum nodosum seaweed and high-grade leonardite potassium humate. With 98% water solubility, this powder delivers maximum nutrient bioavailability for sustainable organic farming operations.

Key Product Features

• 98% Ultra-High Water Solubility: Near-complete dissolution with minimal residue. Ideal for precision irrigation systems including drip tape, micro-sprinklers, and hydroponic setups.
• Triple Organic Certification: OMRI Listed, ECOCERT certified, and produced under ISO 9001:2015 quality management. Fully compliant with USDA NOP, EU Organic Regulation (EC) 834/2007, and JAS organic standards.
• Rich in Natural Biostimulants: Contains alginic acid (2-3%), mannitol, betaines, cytokinins, auxins, and gibberellins that naturally stimulate plant metabolism and cell division.
• Powerful Soil Conditioning: Potassium humate improves soil structure by promoting aggregate formation, enhancing water retention capacity by 30-40%, and increasing cation exchange capacity (CEC) for better nutrient holding.
• Natural Chelating Agent: Humic and fulvic acids naturally chelate micronutrients (Fe, Zn, Mn, Cu), preventing soil fixation and ensuring continuous nutrient availability to crops.
• Enhanced Microbial Activity: Organic carbon from seaweed and humate provides an ideal substrate for beneficial soil microorganisms, building long-term soil fertility.

Application & Usage

Recommended Dosage:

• Foliar Application: 1-2 kg/ha, dilute at 1:1000-1200 ratio, apply every 15-20 days during vegetative and fruiting stages
• Drip Irrigation/Fertigation: 3-5 kg/ha, applied with regular irrigation cycles
• Soil Broadcast/Base Dressing: 15-20 kg/ha mixed with base fertilizer
• Seed Soaking: 0.5-1 kg per ton of seeds, soak for 8-12 hours
• Hydroponics: 0.1-0.2 g/L in nutrient solution, renewed weekly

Suitable Crops: Organic vegetables (lettuce, spinach, kale), fruit trees (apple, citrus, mango, avocado), berries (strawberry, blueberry), cereals (organic wheat, quinoa), pulses, oilseeds, medicinal herbs, greenhouse ornamentals, and turf grass.

Why This Product Stands Out

• 25-35% average yield increase observed in field trials across multiple crop types
• Significantly reduces chemical fertilizer dependency: 20-30% less NPK required when used as complementary treatment
• Improves post-harvest shelf life and fruit firmness through enhanced calcium uptake
• Reduces transplant shock and accelerates seedling establishment
• Compatible with most bio-pesticides and organic input programs
• Non-toxic, non-polluting, and safe for beneficial insects and pollinators
