Zinc Lignosulfonate for Agriculture and Fertilizer Formulations
Zinc Lignosulfonate is a water-soluble zinc-containing lignosulfonate used in fertilizer, crop nutrition, micronutrient blends, soil-related formulations, and selected industrial dispersion or binding systems.
China Lignin supplies GAC-ZnLS for buyers who need zinc relevance together with lignosulfonate dispersion and formulation support. It is best positioned as a zinc micronutrient formulation material, not a stand-alone yield claim.
Micronutrient Relevance
Designed for buyers comparing trace-element lignosulfonate grades for crop nutrition and fertilizer formulation.
Formulation Support
Lignosulfonate behavior may support dispersion, binding, and water-based compatibility in selected systems.
Export Qualification
Confirm TDS, SDS, COA, packing, sample result, destination rules, and label requirements before order.
Answer-First Product Overview
Zinc is important for enzyme activity, auxin metabolism, protein synthesis, internode development, and crop quality. Zinc lignosulfonate can help formulators deliver zinc in a lignosulfonate-based material that supports compatibility testing in water-based and powder systems.
Buyer Note
Zinc availability depends on soil pH, carbonate level, phosphorus interaction, organic matter, crop demand, application method, and formulation design. Confirm zinc assay, solubility, pH, compatibility, and regulatory labeling before order.
Main Specification
Specifications should be confirmed with the latest TDS, COA, SDS, sample result, and commercial contract. Values below are written for product-page qualification and buyer discussion.
| Item | Typical value | Buyer note |
|---|---|---|
| Name | Zinc lignosulfonate | Confirm selected grade before order |
| Product code | GAC-ZnLS | Use for quotation and sample reference |
| Appearance | Yellow brown to brown powder | Useful for handling and visual acceptance |
| Dry matter | 95% min | Supports solids and loading calculation |
| Water-insoluble | 1.0% max | Relevant for spray and filtration systems |
| Sulfate | 2% min | Confirm if salt sensitivity matters |
| Total zinc | around 3% or 2-5% | Confirm exact zinc assay by COA |
| Lignosulfonate | 55% min or 50-60% | Main lignin-derived formulation component |
| Moisture | 7% max | Important for flowability and storage |
Agriculture and Fertilizer Applications
Use should be selected by crop target, formulation route, micronutrient requirement, compatibility, dosage, local regulation, and buyer testing rather than by product name alone.
Zinc Fertilizer
Useful for formulations targeting zinc deficiency or zinc nutrition programs.
Foliar Nutrition
Evaluate crop safety, pH, spray water quality, and tank-mix compatibility.
Seed and Early Growth Concepts
Relevant where zinc supports early growth, but germination and dust-off tests are required.
Soil Application
Consider soil pH, phosphorus level, and zinc fixation risk.
Micronutrient Blends
Can be combined conceptually with iron, manganese, copper, boron, or trace-element systems after compatibility testing.
Granular Fertilizer
May support zinc addition and binding behavior in selected granulation systems.
Grade Selection Guide
Choose the grade by nutrient assay, application method, solubility requirement, water quality, pH compatibility, crop sensitivity, packaging, and required documentation.
- Zinc assay target
- Foliar vs soil application
- Phosphorus interaction risk
- pH and water hardness
- Blend compatibility
- Local label requirements
Industrial Applications
Trace-element lignosulfonates can also be evaluated in selected industrial systems. Performance should be treated as grade-specific and process-specific.
| Industrial use | Common role | Buyer check |
|---|---|---|
| Ceramic and pigment systems | Dispersion support where zinc content is acceptable | Check color and process compatibility |
| Binder systems | Powder binding and handling support | Test strength and moisture behavior |
| Dust suppression | Lignosulfonate binding support | Check zinc environmental limits |
Packaging, Documents, and Related Products
Common export supply includes 25 kg woven bags with inner liner, palletizing, moisture protection, and buyer-approved packaging. Buyers should request TDS, SDS, COA, packing list, invoice, sample information, and application notes where available.

FAQ
What is zinc lignosulfonate used for?
Zinc lignosulfonate is used or evaluated for zinc-containing fertilizer formulations, foliar nutrition, micronutrient blends, granular fertilizer, soil-related products, and selected industrial dispersion or binding systems.
Can zinc lignosulfonate be used in foliar fertilizer?
It may be evaluated for compatible foliar systems, but buyers should test crop safety, pH, water quality, zinc rate, and tank-mix compatibility.
How should buyers choose zinc lignosulfonate?
Buyers should compare zinc assay, lignosulfonate content, water-insoluble level, pH, moisture, documents, and application testing results.
