3. Physical Properties
| Property | Value |
|---|---|
| Bulk Density | 550 – 750 kg/m³ |
| Particle Size (granular) | 1 – 4 mm (90% min) |
| Particle Size (powder) | ≤ 200 mesh (95% min) |

4. Key Functional Properties
- High nitrogen content combined with humic substances provides both immediate and slow-release nitrogen nutrition.
- Improves soil cation exchange capacity (CEC), soil structure, and microbial activity.
- Enhances nutrient use efficiency (NUE) and reduces nitrogen leaching.
- Chelates micronutrients (Fe, Zn, Mn, Cu) and improves their plant availability.
- Stimulates root development and increases drought resistance.
5. Agricultural Performance (Field Results Summary)
| Crop | Typical Application Rate | Observed Benefits |
|---|---|---|
| Cereals (wheat, corn) | 50 – 150 kg/ha | 8 – 18% yield increase, 10 – 25% N-saving |
| Vegetables | 100 – 300 kg/ha | Improved quality, earlier harvest |
| Fruit trees | 200 – 500 g/tree | Increased fruit size, better color |
| Turf & ornamentals | 50 – 100 g/100 m² | Darker green color, stronger root system |
6. Recommended Application Methods
- Soil broadcast or banding (granular form)
- Fertigation/drip irrigation (highly soluble grades)
