Humic Fulvic Acid Concentrated Liquid
The Concentrated Blend — More Active per Litre
Every lot ships with a Certificate of Analysis stating actual tested values.
Product Overview
Humic Acid Liquid is JINGFENG’s mineral-source liquid humic and fulvic acid, extracted from leonardite and fully dissolved in water. It is a black, free-flowing liquid rich in humic substances that improves soil structure, chelates nutrients and boosts fertilizer efficiency in fertigation and foliar programmes. Potassium-free, chlorine-free and hormone-free, it is compatible with most soluble fertilizers and safe for drip, sprinkler and flood irrigation.
Humic Fulvic Acid Concentrated Liquid is the high-active end of our liquid line, carrying 210 g/L humic acid and 200 g/L fulvic acid in a fully dissolved solution. It is built for formulators and growers who want maximum humic/fulvic load per litre — fewer drums to handle, more active carbon per hectare.
Like the original blend it is 100% water-soluble, potassium-free, chlorine-free and hormone-free, with no sediment. Use it in high-value fertigation and foliar programmes, or as the concentrated base of a private-label liquid fertilizer where the humic/fulvic guarantee is the selling point.
Key Benefits
210 g/L humic + 200 g/L fulvic
The highest active load in the family — more humic/fulvic per litre, fewer drums to store and ship.
Concentrated yet clean
Fully dissolved, no sediment, no clogged drippers — concentration without the handling penalty.
Fast foliar + deep soil
Fulvic for quick uptake, humic for soil structure and chelation, in one product.
Formulator-ready
A concentrated base for private-label liquid feeds; compatible with MAP, MKP and chelates.
Salt-friendly
Potassium-free and chlorine-free — high active load without raising the salt index.
COA on every batch
Each lot ships with a Certificate of Analysis stating tested organic matter, humic, fulvic, K2O and pH.

Form: black, free-flowing concentrated liquid. Homogeneous and stable; a light shake before use is enough.
In the system: inject into fertigation or add to the spray tank. Even at this concentration it disperses fully with no residue. Dilute to the working rate before it enters the line.
Handling: avoid eye contact and rinse after handling. Store sealed and use soon after opening.
How the liquid humic line compares
| Grade | Form | Humic acid | Fulvic acid | K₂O | Best for |
|---|---|---|---|---|---|
| Humic Acid Original Liquid | Liquid | ≥ 125 g/L | — | 20 g/L | Straight humic for soil & roots |
| Humic Fulvic Acid Original Liquid | Liquid | ≥ 125 g/L | ≥ 125 g/L | 20 g/L | Balanced humic + fulvic |
| Humic Fulvic Acid Concentrated Liquid (this product) | Liquid | ≥ 210 g/L | ≥ 200 g/L | 40 g/L | High-active concentrate |
All grades are fully water soluble, potassium-free and chlorine-free. Dilute before the irrigation or spray line.
Applications & Dosage
For high-value fertigation, foliar and concentrated liquid-formula bases.
| Application | How to use | Rate |
|---|---|---|
| Drip / micro-spray irrigation | Inject at the lower rate — the concentrated load goes further per litre. | 0.5–1.0 L per 660 m² |
| Foliar spray | Dilute 1:1000–1:1500 and spray in the cool part of the day. | 0.3–0.6 L per 660 m² |
| Concentrated formula base | Use as the humic/fulvic base of a high-active soluble feed; compatible with MAP, MKP and chelates. | 5–10% of formula |
| Seed / transplant dip | Dilute 1:800–1:1000 and dip roots at planting. | 1:800 – 1:1000 |
Packaging & Storage
| Pack size | Description |

Frequently Asked Questions
Why concentrated over the original blend?
The concentrated blend carries roughly 210 g/L humic and 200 g/L fulvic versus 125/125 in the original — more active per litre, fewer drums. Use the original when the per-litre cost matters more than the load.
Is it still fully soluble?
Yes. Even concentrated, it dissolves completely with light agitation and leaves no residue.
How do I dose it?
Lower rate than the original blend — 0.5–1.0 L per 660 m² in fertigation, diluted 1:1000–1:1500 for foliar. Always dilute before the line.
Will it clog drip lines?
No — fully dissolved, inject through the normal fertilizer injector and filter as usual.
Do you provide a COA per batch?
Yes — tested organic matter, humic acid, fulvic acid, K2O and pH against Chinese industry standards.
What is the minimum order and lead time?
Stock item. MOQ one pallet; 7–15 days ex-works. Private-label bottling available.
