Liquid potassium lignosulfonate is evaluated as a lignin-derived formulation ingredient where potassium contribution, dispersion or binding is relevant. Agricultural suitability must be confirmed for the exact commercial grade and finished formulation. This guide explains the available GAC-KLS-L technical data and the checks needed before fertilizer, soil or crop-use trials.
GAC-KLS-L: documented reference data
Source: Green Agrochem, Liquid Potassium Lignosulfonate Technical Data Sheet, document GAC-KLS-L, Rev. 2.0. The PDF and editable version agree. The TDS calls these typical production results for reference, not binding specifications, even where its table uses minimum or maximum notation. Confirm contractual limits and actual shipment results separately.
| Parameter | TDS reference value | Interpretation and confirmation needed |
|---|---|---|
| Appearance | Black liquid | Check colour contribution in the finished formulation. |
| Solid content | 45% min | Confirm the measurement method and actual batch solids before calculations. |
| Water-insoluble matter | 2.5% max | Confirm reporting basis and filtration method; qualify screens and nozzles. |
| Lignosulphonate content | 45% min | Dry-basis versus as-supplied basis and assay method need confirmation. |
| K₂O content | 8–10% | Reporting basis is not stated. Do not calculate a nutrient application rate until confirmed. |
| Reducing sugar | Around 4% | Typical value; confirm basis and method where relevant to formulation stability. |
| Density | 1.20–1.30 g/ml | Measurement temperature is not stated; obtain batch data for volume-to-mass conversion. |
| pH | 4.0–7.0 | Test concentration and temperature are not stated. This range does not establish crop safety. |
The available GAC-KLS-L-COA document is marked Rev. Template and explicitly labels its results as illustrative. It is not an actual shipment certificate. Request a completed, authorized batch COA with appropriate test methods.
Confirm agricultural suitability before formulation
The TDS mentions agricultural applications but also carries a Construction label and lists industrial uses. Neither a potassium content nor a broad application list establishes fertilizer registration, organic-input eligibility, foliar suitability or crop safety. Confirm the intended use with the supplier and review the exact grade against the destination-market requirements.
For product-family context, see potassium lignosulfonate. Do not substitute potassium lignohumate, powder-grade or mixed potassium/calcium product data for this liquid grade.
Build a controlled formulation trial
- Define the intended function: formulation aid, binding contribution or documented nutrient contribution.
- Obtain confirmed assay bases, current technical documents and an actual batch COA.
- Compare against the existing formulation while holding water quality, ingredients, mixing sequence and process conditions constant.
- Record precipitation, settling, viscosity, foam and filtration behaviour immediately and after the intended storage period.
- Verify equipment compatibility and complete appropriate crop or soil trials before commercial use.
For broader formulation and handling considerations, see the liquid lignosulfonate agriculture guide. Formulation performance must still be verified for this specific grade.
Recommended dosage: what is documented?
The reviewed GAC-KLS-L Rev. 2.0 TDS does not provide an agricultural starting dosage or dilution ratio. Request a documented supplier-recommended starting trial range that identifies the application, exact grade and calculation basis. Do not treat a generic dilution ratio as a validated foliar or irrigation rate.
Likewise, this document does not substantiate a fixed crop-yield increase, heavy-metal removal percentage, toxin breakdown or improved animal nutrient absorption. Such outcomes require their own identified test system and evidence; product composition alone cannot establish them.
Packaging and handling information
The TDS lists flexitank or IBC packaging according to customer requirements, cool, dry, well-ventilated storage with protection from freezing, and a 12-month shelf life from manufacture under recommended storage conditions. It advises avoiding mist inhalation and eye or skin contact and keeping containers closed. Obtain the current product-specific SDS and confirm its applicability before handling or shipment.
Request a qualification document set
Send the proposed formulation, intended crop or process, water analysis, destination market and acceptance criteria to info@greenagrochem.com. Ask for GAC-KLS-L Rev. 2.0 data confirmation, percentage reporting bases, relevant test methods, a current SDS and an actual batch COA before agreeing a trial or purchase specification.
