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 Powder (Alga GSP 50%) is the premium green powder: ≥ 40% alginate, ≥ 50% algal oligosaccharides, ≥ 60% organic matter and potassium as K₂O ≥ 18%, plus calcium, magnesium and a full micronutrient spread. It is a green powder, 100% water soluble, for premium organic and compound fertilizer blends.

Frequently Asked Questions
What is the potassium content?
Potassium as K₂O is ≥ 18%, with calcium ≥ 1.2% and magnesium ≥ 0.4% for a broader nutrient spread than the brown Bio-Alga BSP.
How is it different from the green No NPK powder?
The Alga GSP 50% grade carries nitrogen and potassium (K₂O ≥ 18%) plus Ca and Mg, while the green No NPK grade has none — pick Alga GSP 50% when you want a built-in nutrient 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.
