Product Overview
Sodium lignosulfonate is the sodium salt form of lignosulfonate, a water-soluble lignin derivative valued for anionic dispersing behavior, binding performance, and compatibility with many water-based agricultural and industrial systems.
The Agri Grade TDS lists four farm uses: soil conditioning, binder and dispersant in fertilizer granulation, and dispersant in pesticide formulations. This page covers how agricultural buyers use it; the dispersion chemistry behind pesticide formulations is explained on greenagrochem.net.
Agriculture and Fertilizer Applications
Fertilizer Granulation
Listed in the TDS as a binder and dispersant in fertilizer granulation, to reduce dust and improve flow. Check granule strength, moisture and drying on your own line.
Coated and Slow-Release Fertilizers
Lignosulfonate is also tested in fertilizer coatings. See lignosulfonate for coated and slow-release fertilizers.
Pesticide Formulations
Listed as a dispersant in pesticide formulations. For WP, WDG and SC dispersant choice and test methods, see dispersants for SC and WDG agrochemicals.
Soil Conditioning
Listed in the TDS for soil conditioning. Results depend on soil and rate, so confirm in a field trial. Compare with humic products in lignosulfonate vs humic acid.
Micronutrient Blends
Used to carry and disperse trace elements in blends. See lignosulfonate vs EDTA chelates for the trade-offs.
Liquid Tank Mixes
Before adding it to a tank mix, check compatibility with a jar test.

Grade Selection Guide
For fertilizer granulation, buyers should test dosage, moisture level, drying condition, particle size distribution, and compatibility with NPK or mineral ingredients.
For pesticide formulations and crop-input blends, check pH, water hardness, compatibility with the active ingredient, storage stability and local registration requirements.
Packaging and Loading
Sodium lignosulfonate is commonly supplied as powder in export packaging suitable for container shipment.
Packing: 20 kg or 25 kg woven bags with a polyethylene liner, or 500 kg / 600 kg jumbo bags (FIBC). Custom packing is available on request.
Storage: keep sealed in a cool, dry, ventilated place. Shelf life is 24 months from production in the original unopened packing.
Buyer Checklist
FAQ
What is sodium lignosulfonate used for in agriculture?
The Agri Grade TDS lists soil conditioning, binder and dispersant in fertilizer granulation, and dispersant in pesticide formulations. It is also used to carry trace elements in micronutrient blends.
Can sodium lignosulfonate be used in fertilizer granulation?
Yes. It may be evaluated as a fertilizer granulation binder. Performance depends on product grade, dosage, moisture level, fertilizer ingredients, granulation equipment, drying conditions, and target granule strength.
Is sodium lignosulfonate suitable for soil-related formulations?
It can be considered as a lignin-derived formulation component in soil-related products, but it should not be treated as a universal soil performance guarantee. Suitability should be confirmed by formulation and field context.
What are the Agri Grade specifications?
Typical values: pH 7.0 – 9.5, dry matter 95% min, lignosulphonate 55% min (dry basis), water-insoluble matter 1% max, sulphate 2 – 5%, calcium and magnesium 0.5% max, reducing sugar 7% max. The batch COA gives the actual results.
How is it packed?
20 kg or 25 kg woven bags with a polyethylene liner, or 500 kg / 600 kg jumbo bags. Custom packing can be arranged.
What documents should buyers request?
Buyers should request the current TDS, SDS, COA, sample information, packaging details, and available application guidance for the intended formulation.
How should I choose between sodium, calcium, and liquid lignosulfonate?
Choose by solubility, cation type, application system, handling preference, pH compatibility, transportation form, and performance testing. Sodium lignosulfonate is often selected where water solubility and dispersing behavior are important.
