Manganese Lignohumate
Manganese–Lignohumate Micronutrient for Crop Nutrition and Soil Programs
Manganese Lignohumate is a micronutrient material combining manganese with a lignohumate organic matrix. It is developed for agricultural fertilizer systems where manganese supply, organic functionality and soil-oriented formulation objectives are evaluated together.
Micronutrient–Lignohumate Technology
Manganese behavior depends strongly on soil pH, redox conditions, drainage and crop demand. GAC-MnLSHA provides a defined manganese assay in a lignohumate matrix for analysis-led formulation and field validation.
Manganese Contribution
Approximately 3% total manganese in the standard grade.
Low Insoluble Matter
Maximum 1% water-insoluble matter.
Defined Bulk Property
Typical density 0.532 g/cm³ for process evaluation.
Product Characteristics
- High dry matter for transport and formulation.
- Minimum 55% lignohumate content.
- Maximum 7% moisture.
- Standardized micronutrient grade with batch COA support.
- Defined density for handling and blend-development calculations.

Applications
Agricultural Fertilizers
For foliar, soil and irrigation micronutrient formulation trials.
Organic-Mineral Blends
Manganese-containing organic component for fertilizer development.
Soil Conditioners
For combined micronutrient and soil-oriented programs.
Compound Fertilizers
For qualified powder or granular blends after uniformity testing.
Application Development
| Application Route | Development Requirement |
|---|---|
| Foliar development | Verify crop safety, concentration and tank-mix compatibility. |
| Irrigation systems | Confirm filtration, pH, oxidation and precipitation behavior. |
| Soil application | Set rates from soil pH, redox, drainage and crop analysis. |
| Dry blends | Verify density matching, assay uniformity and segregation control. |
No universal field rate is stated. Final concentration and application rate require crop, soil, water-quality, compatibility, regulatory and field validation.
Technical Considerations
- Manganese availability is strongly influenced by soil pH and redox conditions.
- Poor drainage can materially change manganese behavior and crop response.
- Confirm water quality and compatibility before liquid application.
- Both manganese deficiency and excess must be considered in rate selection.
Quality Control
Release controls include identity, appearance, dry matter, moisture, total total manganese, lignohumate, sulphate and water-insoluble matter where specified. Batch identification and retained QC records support supply consistency.
