Calcium Lignohumate Granules
Granular Calcium–Lignohumate Soil Conditioner for Fertility Programs
Calcium Lignohumate Granules are a soil-applied granular material combining a calcium-containing salt fraction with lignohumate-related organic functionality. The grade is developed for soil conditioners, base fertilizers and granular fertility programs.
PRODUCT STANDARD
GAC-CaLSHA-G
Product Technology
The product is designed for dry blending and direct soil-oriented programs where granule handling, partial water solubility and organic-mineral functionality are required together.
Granular Delivery
Suitable for dry blending and soil application.
Partial Solubility
Minimum 50% water solubility; not presented as fully soluble.
Organic Matrix
Minimum 50% lignosulfonate-related content.
Product Characteristics
- Black granular form.
- Suitable for base-fertilizer and soil-conditioner blends.
- Defined alkaline pH range.
- Partial-solubility profile for soil use.
- Batch COA and technical documentation support.
Technical Properties
Product standard: GAC-CaLSHA-G · Form: Black granules
| Parameter | Typical Specification |
|---|---|
| Appearance | Black granules |
| pH | Around 9–10 |
| Water solubility | ≥ 50.0% |
| Total salt | ≥ 7% |
| Lignosulfonate | ≥ 50% |
Typical production values support technical evaluation. Final acceptance criteria and batch results are governed by the approved specification, contract and shipment Certificate of Analysis.
Applications
Soil Conditioners
For granular programs targeting soil structure and fertility.
Base Fertilizer Blends
For dry compound and bulk-blended fertilizers.
Organic-Mineral Fertilizers
For combined mineral and lignin-humic functionality.
Granular Soil Programs
For field applications requiring robust handling.
Application Development
| Application Route | Development Requirement |
|---|---|
| Dry blending | Match particle size and density; verify segregation resistance. |
| Compound fertilizer | Test thermal and mechanical compatibility. |
| Soil conditioner | Set inclusion from soil analysis and formulation targets. |
| Direct soil use | Validate field rate under local crop and soil conditions. |
No universal field rate is stated. Establish final dosage through compatibility, process, regulatory, crop, soil and field validation.
Technical Considerations
- The grade is partially soluble and is not a fully soluble fertigation material.
- The TDS states total salt rather than elemental calcium; do not represent it as a guaranteed calcium assay.
- Confirm soil pH, salinity and total nutrient balance.
- Validate granule integrity and blending uniformity.
Quality Control
Release controls cover appearance, pH, water solubility, total salt, lignosulfonate-related content and batch identity.
