Product Overview
Seaweed extract is a water-soluble organic biostimulant produced from marine brown algae. JINGFENG’s Ascophyllum nodosum extract is obtained by physical crushing followed by enzymatic or biochemical hydrolysis, so the algae’s own alginic acid, seaweed polysaccharides, mannitol, betaine, amino acids and natural plant growth regulators (auxins, cytokinins and gibberellins) are preserved intact. The enzymatic range below is fermented and colour-graded (green, brown and black) for different formulation and label needs, and includes NPK-free grades for organic-only blends.
Enzymatic Green Seaweed Extract Liquid (Alga L 40%) is the high-load green liquid biostimulant: a fermented Ascophyllum nodosum extract with ≥ 40% seaweed oligo and ≥ 20% alginic acid, plus nitrogen, phosphorus and potassium. It is green, 100% water soluble and dissolves instantly for foliar and fertigation programmes.
Key Benefits
High-load liquid
≥ 40% seaweed oligo and ≥ 20% alginic acid in a single liquid dose.
Ready-to-use
No pre-dissolving — mixes straight into the spray tank or irrigation line.
Built-in N, P and K
Contains nitrogen, phosphorus and potassium so it works as a standalone foliar feed.
Natural growth regulators
CTK / IAA ≥ 610 ppm from the seaweed’s own phytohormones.
COA on every batch
Each lot ships with a Certificate of Analysis stating the tested values against Chinese industry standards.

Frequently Asked Questions
How do I dilute it?
Dilute 1:800 – 1:1500 with clean water for foliar spraying, or 1:1000 – 1:2000 for drip / flood irrigation. Always add the product to water, not water to the product.
How is it different from the 15% brown liquid?
The green 40% liquid leads on seaweed oligo (≥ 40% vs ≥ 15%) and alginic acid (≥ 20% vs ≥ 8%) — a higher-load dose for programmes that want more seaweed active per litre.
Is it ready to use?
Yes — it is a liquid, so no pre-dissolving step is needed. It mixes straight into the spray tank or irrigation line.
Is it 100% water soluble?
Yes — 100% water soluble with no residue, safe for drip lines, micro-sprinklers and spray tanks.
Do you provide a COA per batch?
Yes. Every shipment travels with a Certificate of Analysis stating the tested seaweed oligo, alginic acid and N-P-K.
What is the minimum order and lead time?
Standard stock item. MOQ one pallet of bottles / drums; 7 – 15 days ex-works. Private-label printing available on request.
