Product Overview
Molten-Process Humic Acid Urea is a high-efficiency, eco-friendly compound fertilizer that integrates humic acid (HA) with urea via advanced molten-state technology. Unlike traditional blended/coated types, it achieves uniform HA dispersion in the urea matrix, ensuring superior stability, nutrient synergy, and performance—ideal for modern precision and sustainable agriculture.Core Manufacturing Process
Urea is melted at 132-138℃, then mixed with activated HA (mineral-based) and optional trace elements. High-speed mixing, granulation, and low-temperature curing produce uniform, dust-free granules with tight HA-urea combination, avoiding nutrient segregation. The process preserves HA activity, optimizes nitrogen release, and forms a “slow-release + synergistic absorption” mechanism.Technical Details

FAQ
1. Where does the humic acid in Humic Acid Urea come from, and what is its core function?
2. How does it differ from conventional urea?
3. What are the main types of Humic Acid Urea?

- Non-coated Humic Acid Urea (HA uniformly mixed with urea, including molten-process and blended types, cost-effective and versatile).
4. Why is molten-process Humic Acid Urea recommended?
5. Is Humic Acid Urea safe for crops and soil?
6. How does it compare with controlled-release urea (CRU)?
