Ammonium Humate is a natural organic fertilizer produced by reacting high-quality humic acid (extracted from leonardite) with ammonia. It combines slow-release organic nitrogen and highly active humic substances in one product, providing both immediate and long-term nutrition while improving soil health.
Main Specifications
| Parameter | Specification |
|---|---|
| Total Humic Acid (dry basis) | ≥ 60 % |
| Water-soluble Humic Acid | ≥ 85 % |
| Total Nitrogen (N, dry basis) | 5 – 7 % |
| Ammonium Nitrogen (quick part) | 2 – 4 % |
| Organic slow-release Nitrogen | 2 – 4 % |
| Moisture | ≤ 12 % |
| pH (1 % solution) | 7.5 – 9.5 |
| Water Solubility | ≥ 90 % |
| Particle size (powder) | 80 – 200 mesh |
| Granular size (if granular) | 1 – 4 mm |
Main Benefits
- Gives plants both quick and slow nitrogen – no sudden growth flush, no burning.
- Supplies 5–7 % gentle organic nitrogen that lasts longer than urea or ammonium sulfate.
- High humic acid (≥ 60 %) improves soil structure and feeds microbes right away.
- Works great as starter fertilizer for rice, corn, vegetables, and transplanting.
- Increases root growth and seedling vigor in the first 20–30 days.
- Reduces nitrogen leaching and volatilization loss in wet or sandy soils.
- Dark color warms the soil faster in cold seasons and helps germination.
- Safe for young plants and can be used in organic programs (many grades are OMRI-listed).
- One application covers early growth stage and improves soil for the whole season.
How to Use
- Broadcasting or band placement before planting
- Side-dressing for rice, maize, vegetables
- Mix into transplanting water or nursery media
- Can be dissolved for foliar spray (0.5 – 1 kg/ha)
Typical Rates
- Rice & field crops: 50 – 150 kg/ha
- Vegetables & transplanting: 80 – 200 kg/ha
- Nursery media: 2 – 5 kg/m³
Packaging
- 25 kg kraft or PP bag with inner liner
- 20 kg bag, 5 kg bag (retail)
- 500 – 1000 kg big bag
Key Advantages
- Much safer than straight ammonium sulfate or urea
- Nitrogen + humic acid in one bag – saves labor
- Less smell and less loss than normal ammonium fertilizers
- Good price, long-lasting effect
Storage
