Lignosulfonates may be evaluated in fertilizer processing, nutrient formulations and selected soil- or crop-related trials. These agricultural uses are managed by ChinaLignin, the Green Agrochem Agriculture Division, rather than LigninCorp’s Industrial Chemicals division.
Use the full Ammonium and Potassium Lignosulfonates in Agriculture: Evidence and Trial Guide for counter-ion selection, exact-grade documentation, formulation checks, dosage language, crop-safety testing and regulatory boundaries.
What Must Be Verified
- Exact product code, counter-ion identity, solids/moisture, pH method, elemental analysis and impurities.
- Whether the intended function is fertilizer granulation, binding, dispersion, metal-ion complexation or a soil/crop research question.
- The calculation basis for any application amount and the delivered nitrogen, potassium, sulfur and total salts.
- Formulation compatibility, storage stability and processing performance before field evaluation.
- Replicated crop/soil trials, phytotoxicity monitoring and destination-market authorization for fertilizer, pesticidal or disease-control claims.
Former Numerical Claims—Evidence Status
| Former statement | Status | Required treatment |
|---|---|---|
| Ammonium lignosulfonate contains 6–8% nitrogen. | Unverified for the exact offered grade and analytical basis. | Use only current exact-grade elemental analysis/TDS and COA data. |
| Soil mixtures of 0.5%, 1.0% or 2.0% produced defined pH, microbial or pathogen effects. | Research-style figures were detached from source, soil, material identity, denominator and method. | Do not treat as supplier dosage. Cite the complete study system or omit the performance conclusion. |
| Bacteria increased from 300 million to more than 100 billion per gram; fungi increased by more than two log units. | Unverified experimental results without an adjacent primary source or complete conditions. | Not a commercial product claim; restore only as clearly labelled literature data after source verification. |
| More than 50% microsclerotia killed, nematodes reduced by over 60% or 95%, and disease delayed by 6–8 weeks. | Unsupported efficacy claims and potential regulated pesticidal/disease-control claims. | Quarantined from product promotion; requires the original study plus jurisdiction-specific regulatory review. |
| Guaranteed maximum disease control with zero crop harm. | Absolute and unsafe claim contradicted by the page’s own phytotoxicity discussion. | Removed as indefensible. Crop safety must be measured under defined conditions. |
Correct Agriculture Routes
For exact products, review Ammonium Lignosulfonate and Potassium Lignosulfonate. Send the crop or formulation, target function, water and soil conditions, current inputs, trial design, required documents and destination market to ChinaLignin technical support or info@greenagrochem.com.
Division note: LigninCorp continues to handle industrial lignosulfonate procurement for concrete, ceramics, mining, drilling, dust control and industrial binding. Agricultural product selection and agronomic evidence belong to ChinaLignin.
