Copper Lignohumate for Agriculture and Fertilizer Formulations
Copper Lignohumate Copper Lignohumate is a copper-bearing humate-lignin product for micronutrient fertilizer, organic-mineral blends, granular coating, and selected soil or crop nutrition programs.
It should be positioned carefully: copper is an essential micronutrient at low levels, but excessive copper can create phytotoxicity, residue, soil accumulation, and regulatory concerns. The product page should make China Lignin look technically responsible, not promotional at any cost.

Buyer Note
Copper-containing products require especially careful dosage, crop-sensitivity, residue, label, and local regulatory review. Do not recommend blanket usage rates on the product page.
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 | Copper lignohumate | New product page draft |
| Product code | GAC-CuLH | Use for sample and quotation reference |
| Appearance | Brown to black powder | Confirm current sample |
| Total copper | 2-5% by grade | Confirm exact Cu assay by COA |
| Humic substances | By COA | Key soil-related indicator |
| Lignin / lignosulfonate fraction | By COA | Key formulation indicator |
| Moisture | 15% max or by grade | Check storage stability |
| pH | By grade | Important for compatibility and crop safety |
| Water solubility | By grade | Confirm by target application |
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.
Copper Micronutrient Programs
For controlled copper-relevant crop nutrition concepts after soil, crop, and regulatory review.
Organic-Mineral Fertilizer
Can be evaluated in trace-element fertilizer blends with humic-lignin positioning.
Granular Fertilizer Coating
Useful where copper addition and organic coating behavior are both required.
Specialty Crop Inputs
May fit markets where copper micronutrient products are allowed and carefully managed.
Private Label Supply
Requires clear COA, SDS, label review, and destination-market compliance checks.
Comparison Product
Connects with copper lignosulfonate and trace element lignosulfonate blend pages.
Grade Selection Guide
Select the grade by assay, solubility, pH, application method, handling, regulatory fit, and the buyer’s required documentation.
- Cu assay and legal limits
- Crop sensitivity
- Residue and soil accumulation
- Humic substance level
- pH and solubility
- SDS and label review
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 |
|---|---|---|
| Granular fertilizer | Copper-bearing organic matrix | Check assay uniformity and local limits |
| Powder blending | Trace element humate-lignin component | Check segregation and dust |
| Custom blends | Controlled copper input | Check compatibility with other trace elements |
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
What is copper lignohumate used for?
It is evaluated as a copper-bearing humate-lignin product for micronutrient fertilizer, organic-mineral blends, and granular coating concepts.
Can copper lignohumate be used on every crop?
No. Copper dosage, crop sensitivity, residue concerns, soil accumulation, and local rules must be reviewed before use.
How should copper lignohumate be compared with copper lignosulfonate?
Copper lignohumate emphasizes a humate-lignin matrix, while copper lignosulfonate emphasizes lignosulfonate-based solubility, dispersion, and complexing behavior.
