Seaweed Extract 30% — Ascophyllum Nodosum, ≥ 30% Alginic Acid
A cold-water extract of brown seaweed standardised to 30% alginic acid on a dry basis, carrying alginates, mannitol and betaines, supplied through the qualified partner network.

- Indicative Use (foliar)1 – 2 kg/ha
- Indicative Use (fertigation)3 – 5 kg/ha
What This Product Is
Seaweed Extract 30% is a cold-water extract of the brown seaweed Ascophyllum nodosum, standardised to 30% alginic acid on a dry basis as certified in the supplier TDS and COA. Other assay bases are available on request, which matters because seaweed extracts are quoted on several different bases across the market.
It contains alginates, mannitol, betaines and other bioactive compounds that may influence plant signalling and stress responses. It is used alongside amino acid programmes rather than instead of them: the amino acid powder supplies organic nitrogen and free amino acids, the seaweed extract supplies the signalling chemistry.
Like the rest of the complementary range it is partner-supplied, pre-vetted for production consistency and documentation, and consolidated free of charge into the same container as your amino acid order.
What You Get
- ≥ 30% alginic acid on a dry basis, certified in the supplier TDS and COA
- Cold-water extraction from Ascophyllum nodosum
- Alternative assay bases available on request, so quotations can be compared like for like
- Pairs with amino acid programmes for stress tolerance and root development work
- Consolidated free of charge into one container with the amino acid order
Who Buys It
- Biostimulant formulators combining seaweed and amino acid chemistry
- Distributors building a stress-tolerance product line
- Horticultural programmes focused on root development and recovery
- Buyers consolidating several inputs into one container
What It Fixes
- Seaweed quotations on incompatible assay bases
- Sourcing a biostimulant input and an amino acid input from two unconnected suppliers
- Documentation arriving after the goods rather than before the order
- Part-container quantities that no single supplier wants to ship
How It Is Made And Supplied
- Species: Ascophyllum nodosum, brown seaweed
- Cold-water extraction
- Standardised to alginic acid on a dry basis per the supplier TDS/COA
- Contains alginates, mannitol and betaines among other bioactive compounds
- Packed in 25 kg or 20 kg kraft bags
- Partner-supplied, consolidated at the Suzhou warehouse
Technical Data

How It Compares With The Alternatives
| Against amino acid powder | Seaweed extract is used for signalling compounds such as alginates, mannitol and betaines. Amino acid powder supplies organic nitrogen and free amino acids. They are complementary. |
|---|---|
| Against fulvic acid | Fulvic works as a carrier and chelating chemistry; seaweed extract is standardised on alginic acid and used for plant signalling and stress response. |
| Against a seaweed extract quoted on another basis | Ask for the assay basis before comparing. This product is standardised on alginic acid, dry basis, and other bases are available on request. |
From Sample To Production Batch
Step 1
Confirm which assay basis the quotation uses before comparing suppliers.
Step 2
Request the supplier TDS and COA with the pre-shipment sample.
Step 3
Start at the indicative foliar or fertigation rate and validate by crop and formulation.
Step 4
Check compatibility with the rest of the tank mix at field concentration.
Step 5
Confirm import, registration and labelling in the destination market before shipping.
