Enzymatic Brown Seaweed Extract Powder
The High-Load Brown Powder — Bio-Alga BSP
Every lot ships with a Certificate of Analysis stating the tested values against the stated Chinese industry standards.
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 Brown Seaweed Extract Powder (Bio-Alga BSP) is a high-load enzymatic seaweed powder: ≥ 30% alginate, ≥ 40% algal oligosaccharides, ≥ 60% organic matter and potassium as K₂O ≥ 16%, plus nitrogen and phosphorus. It is a brown powder, 100% water soluble, built for compound and organic fertilizer blending where a firm K₂O floor matters.
Key Benefits
High alginate + oligo
≥ 30% alginate and ≥ 40% algal oligosaccharides in every batch.
Firm K₂O floor
Potassium as K₂O ≥ 16% — a built-in potash load for fertilizer blends.
High organic matter
≥ 60% organic matter feeds soil biology and chelates trace elements.
100% water soluble

Frequently Asked Questions
What is the potassium content?
Potassium as K₂O is ≥ 16% — a firm potash floor that lets you reduce separate KCl inclusion in the blend.
How is it different from the No NPK brown powder?
The Bio-Alga BSP grade carries nitrogen, phosphorus and potassium (K₂O ≥ 16%), while the No NPK brown grade has none — pick Bio-Alga BSP when you want a built-in K load, No NPK when you blend your own.
Is it 100% water soluble?
Yes — 100% water soluble with no residue, safe for drip lines, micro-sprinklers and spray tanks.
Is it suitable for organic farming?
It is a seaweed-derived organic input; ask us for the input list and technical data sheet for your certification body.
Do you provide a COA per batch?
Yes. Every shipment travels with a Certificate of Analysis stating the tested alginate, oligo, organic matter and K₂O.
What is the minimum order and lead time?
Standard stock item. MOQ one pallet; 7 – 15 days ex-works. Private-label printing and custom blends are available on request.
