Fulvic Acid for Agriculture and Fertilizer Formulations
Fulvic Acid Fulvic Acid is a highly water-soluble humic-substance product used in foliar fertilizer, fertigation, micronutrient formulations, seed treatment concepts, biostimulant blends, and specialty crop nutrition programs.
Compared with humic acid and potassium humate, fulvic acid is selected when a buyer needs low molecular weight humic substances, high water solubility, and better fit for foliar or liquid fertilizer systems. It should still be qualified by pH, ash, chloride, heavy metals, compatibility, and local registration requirements.

Answer-First Product Overview
Compared with humic acid and potassium humate, fulvic acid is selected when a buyer needs low molecular weight humic substances, high water solubility, and better fit for foliar or liquid fertilizer systems. It should still be qualified by pH, ash, chloride, heavy metals, compatibility, and local registration requirements.
Buyer Note
Fulvic acid content can be reported by different test methods. Buyers should align the test method and COA standard before comparing quotations from different suppliers.
Main Specification
Specifications should be confirmed with the latest TDS, COA, SDS, sample result, and commercial contract. The values below are buyer-screening ranges for product-page qualification.
| Item | Typical value | Buyer note |
|---|---|---|
| Name | Fulvic acid | Confirm source and test method |
| Product code | GAC-FA | Use for sample and quotation reference |
| Appearance | Yellow brown to dark brown powder or liquid | Depends on grade and concentration |
| Fulvic acid | 50-90% by grade | Benchmark commercial range; confirm by COA |
| Water solubility | 100% | Key for foliar, drip, and liquid fertilizer |
| Moisture | 10% max for powder | Check storage stability |
| pH | 4-7 or by grade | Important for compatibility |
| Ash / inorganic salts | By grade | Confirm where low-salt formulation is required |
| Heavy metals | Comply with destination-market requirements | Request SDS and COA |
Agriculture and Fertilizer Applications
Application should be selected by crop, soil test, water quality, formulation route, compatibility, dosage, and destination-market rules rather than by product name alone.
Foliar Fertilizer
Used in foliar nutrition concepts where full solubility, clarity, and compatibility are required.
Micronutrient Complexing Support
Can be evaluated with trace elements, subject to pH and stability testing.
Fertigation
Suitable for water-based systems after filtration, water-quality, and precipitation checks.
Biostimulant Blends
Used in humic-substance formulations with amino acids, seaweed, or compatible nutrients.
Seed Treatment Concepts
Can be tested in low-rate seed programs according to local rules.
Export Private Label
Useful for distributors needing high-solubility fulvic grades and COA-driven supply.
Grade Selection Guide
Select the grade by assay, solubility, pH, application method, handling, regulatory fit, and the buyer’s required documentation.
- Fulvic assay method
- Solubility and clarity
- pH and salt level
- Powder vs liquid
- Micronutrient compatibility
- Heavy metals and registration
Formulation and Industrial Uses
Some grades can be evaluated beyond field fertilizer programs. Treat all process behavior as grade-specific and test-specific.
| Use | Common role | Buyer check |
|---|---|---|
| Liquid fertilizer | Soluble humic-substance component | Check long-term stability and pH drift |
| Micronutrient blends | Complexing or compatibility support | Test precipitation and color |
| Private-label products | High-solubility humic ingredient | Confirm test method and claim language |
Packaging, Documents, and Related Products
Common export supply can include 25 kg bags with liner, jumbo bags, pallets, moisture protection, sample lots, and buyer-defined packaging. Request TDS, COA, SDS, packing details, sample information, and destination-market label support before order.
FAQ
Is fulvic acid more soluble than humic acid?
In most fertilizer applications, fulvic acid is selected for higher water solubility and easier fit in foliar or liquid systems.
Can fulvic acid complex micronutrients?
It can support micronutrient formulation concepts, but the final product must be tested for stability, pH, clarity, and local label rules.
Why do fulvic acid quotations differ so much?
Differences usually come from raw material, extraction route, test method, assay basis, ash, moisture, and purity requirements.
