- Unbeatable Cost-Effectiveness: Budget-friendly pricing with no compromise on soil-improving performance—cuts input costs vs. premium humic acid fertilizers.
- Hassle-Free Manual Broadcast: Granular form lets you spread by hand (no mixing/dilution needed)—saves time for large fields/orchards without relying on equipment.
- Boost Soil Organic Carbon: Enhances soil organic matter content to improve long-term fertility and water retention.
- Mild Potassium Supplement: Delivers 3% potassium oxide to support steady crop growth without over-fertilization risk.
- Broad Soil Compatibility: Works for sandy, loamy, and moderately compacted soils—ideal for both field crops and fruit orchards.

*Usage Notes
- Avoid mixing with strong acidic fertilizers/pesticides directly (adjust pH to 6-8 if needed).
- Apply once every 10-15 days for top dressing; 1-2 consecutive applications yield best results.
