Product Overview
Bio Fulvic Acid is JINGFENG’s biotech-fermented fulvic acid — produced by microbial fermentation of plant-derived feedstock rather than mined from leonardite. It is a short-chain humic substance rich in fulvic acid, free amino acids, enzymes, sugars and trace nutrients. Fully water soluble and hormone-free, it is used worldwide as a fertilizer raw material and plant biostimulant — chelating nutrients, buffering soil pH, and improving nutrient uptake in foliar, fertigation and blending programmes.
Bio Fulvic Acid Powder 90% is the concentrated end of our fermented fulvate line, guaranteed 90% fulvic acid on a dry basis with 100% water solubility. It is built for concentrated formulations, soluble concentrates and high-value foliar programmes where you want maximum active carbon and minimum inert make-up per kilogram.
At 90% fulvic acid the powder is darker and a little more hydroscopic than the 50%/70% grades, and its pH sits in the 5–7 window rather than 4–6 — both are normal consequences of the higher active load. Fermentation-derived amino acids, enzymes and sugars are still present, so the biostimulant effect is broader than a plain salt.
Use it when your formula is tight on space or you are selling a high-fulvic concentrate. For general blending the 50%/70% grades are the more economical choice; the 90% grade is where the label says ‘90% fulvic acid’.
Key Benefits
90% fulvic acid
The most concentrated grade in the family — minimum inert, maximum active carbon per kilogram.
Fermented, not mined
Carries free amino acids, enzymes and sugars; hormone-free green bio-input.
100% soluble
Dissolves with no residue; suitable for concentrated soluble liquids and foliar concentrates.
Chelates and buffers
Complexes metal ions, frees fixed phosphorus, buffers soil pH toward 5.5–7.0.
Hard-water stable
Anti-flocculation limit 32 meq/g; soluble across pH 1–14 and in saturated brine.
COA on every batch
Tested fulvic acid, pH and moisture against HG/T and NY/T methods, stated on the COA.

Form & Solubility
Form: free-flowing dark brown powder. The highest active load in the family, so a little more hygroscopic than the 50%/70% grades — keep bags sealed.
In water: dissolves completely under light agitation with no residue, ideal for concentrated soluble stocks. Add onto moving water to avoid a surface crust.
Dust: standard PPE at the weighing station recommended, as with any fine powder.
Which powder? 90% for concentrated/high-fulvic labels; 50%/70% for cost-sensitive blending.

Applications & Dosage
| Application | How to use | Rate |
|---|---|---|
| Concentrated soluble formula | Use as the fulvic base of a high-strength WS concentrate at 5–10% of total solids. | 5–10% of formula |
| High-value foliar concentrate | Dilute 1:1000–1:1500; spray every 7–15 days. | 3–7.5 kg/ha |
| Drip / fertigation | Pre-dissolve, filter, then meter into the line. | 7.5–15 kg/ha |
| Compound / bulk-blended NPK | Add 5–10 kg per tonne where a high fulvic guarantee is required. | 5–10 kg/t |
| Seed soaking / root dip | 1:500–1:800 solution, soak 6–12 h. | 1:500–1:800 |
Packaging & Storage

Frequently Asked Questions
Why 90% instead of 50% or 70%?
You get the highest fulvic guarantee per kilogram with the least inert make-up — the grade for concentrated formulas and high-fulvic labels. It costs more per tonne, so for general blending the 50%/70% grades are better value.
Is it still fully soluble?
Yes, 100% water soluble with light agitation and no residue.
Does the pH 5–7 window matter?
It is slightly higher than the 50%/70% grades because of the higher active load — normal for this grade. Account for it if your formula has a tight pH window.
Is it stable in hard water?
Yes — anti-flocculation limit 32 meq/g; soluble across pH 1–14 and in saturated brine.
What is the minimum order and lead time?
Made to order on a fermentation campaign. MOQ higher than the stocked 50%/70% grades; tell us your volume for a firm quote, typically 15–25 days.
Do you supply a COA per batch?
Yes — fulvic acid, pH and moisture tested to HG/T and NY/T methods.
