Potassium Humate for Agriculture and Fertilizer Formulations
Potassium Humate Potassium Humate is a water-soluble humate product used in soluble fertilizer, soil drench, fertigation, seed treatment concepts, granular coating, and organic-mineral fertilizer formulation.
Potassium humate is chosen when buyers want humic substances plus potassium relevance in a more soluble form than ordinary humic acid. It is commonly supplied as black powder, shiny flakes, or granules, with grade selection based on humic acid content, K2O, water solubility, pH, moisture, and filtration behavior.
Product Overview
Potassium humate is chosen when buyers want humic substances plus potassium relevance in a more soluble form than ordinary humic acid. It is commonly supplied as black powder, shiny flakes, or granules, with grade selection based on humic acid content, K2O, water solubility, pH, moisture, and filtration behavior.
Buyer Note
High solubility does not automatically mean universal compatibility. Test with hard water, phosphate, calcium, micronutrients, acids, pesticides, and surfactants before commercial blending or drip use.
Main Specification
Specifications should be confirmed with the latest TDS, COA, SDS, sample result, and commercial contract. The values below are typical ranges for grade screening.
| Item | Typical value | Buyer note |
|---|---|---|
| Name | Potassium humate | Confirm powder, flake, or granule grade |
| Product code | GAC-KH | Use for sample and quotation reference |
| Appearance | Black powder, shiny flake, or granule | Select by process and handling |
| Humic acid | 50–70% (dry basis), by grade | Range across current grade TDS; confirm by COA |
| K2O | 6–10% min (dry basis), by grade | Important nutrient and label indicator |
| Water solubility | 80–100% by grade | Critical for fertigation and liquid fertilizer |
| Moisture | 15% max | Important for storage and flowability |
| pH | 9–10 | Check compatibility with acidic inputs |
| Water-insoluble matter | By grade | Confirm for drip, spray, and filtration systems |
Agriculture and Fertilizer Applications
Application should be selected by crop, soil test, water quality, formulation route, compatibility, dosage, and destination-market rules rather than by product name alone.
Fertigation
Soluble grades can be evaluated for irrigation and drip fertilizer programs after filtration and compatibility testing.
Liquid Fertilizer
Useful in humic liquid fertilizer concentrates when pH, precipitation, and stability are managed.
Soil Drench
Selected for root-zone humate programs and soil nutrient-holding concepts.
Seed Treatment Concepts
Can be tested in seed coating or seed-starting systems where local rules allow.
Granular Coating
Powder or soluble grades may support humic coating on NPK and compound fertilizer.
Private Label Distribution
Suitable for importers needing flakes, powder, granules, COA, SDS, and custom packing.
Grade Selection Guide
Select the grade by assay, solubility, pH, application method, handling, regulatory fit, and the buyer’s required documentation.
- Humic acid and K2O target
- Solubility and filtration
- Powder vs flake vs granule
- pH compatibility
- Hard-water stability
- Label and registration requirements
Formulation and Industrial Uses
Some grades can be evaluated beyond field fertilizer programs. Treat all process behavior as grade-specific and test-specific.
| Use | Common role | Buyer check |
|---|---|---|
| Water-soluble fertilizer | Humate component and potassium contributor | Check precipitation with calcium and phosphate |
| Granular coating | Humic coating material | Check dust, adhesion, and moisture |
| Organic-mineral blends | Humic input in compound fertilizer | Check homogeneity and nutrient declaration |
Packaging, Documents, and Related Products
Common export supply can include 25 kg bags with liner, jumbo bags, pallets, moisture protection, sample lots, and buyer-defined packaging. Request TDS, COA, SDS, packing details, sample information, and destination-market label support before order.
FAQ
How is potassium humate different from humic acid?
Potassium humate is normally more water soluble and contains potassium, while humic acid is often used as a broader soil and granular fertilizer raw material.
Can potassium humate be used in drip irrigation?
Only soluble and low-insoluble grades should be tested for drip use. Water quality, filtration, pH, and compatibility must be checked.
What specifications should buyers request?
Request humic acid, K2O, solubility, water-insoluble matter, moisture, pH, particle size, COA, SDS, and sample results.
