Humic Acid Urea

Humic Acid Urea 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.

Humic Acid Urea FAQ

1. Where does the humic acid in Humic Acid Urea come from, and what is its core function?

The humic acid mainly comes from one sources: Mineral sources (extracted from lignite, weathered coal, etc.);

Its core functions are: improving soil aggregate structure, promoting beneficial microbial activity, enhancing crop nutrient absorption capacity, and improving crop resistance to drought, cold and diseases.

2. How does it differ from conventional urea?

Unlike regular urea (only 35% nitrogen utilization rate, short efficacy, soil degradation risk), it inhibits urease activity to reduce ammonia volatilization (30-50%), extends efficacy to 60-100 days, improves nitrogen utilization to 60-70%, and enhances soil health long-term.

3. What are the main types of Humic Acid Urea?

Two core types:

Coated Humic Acid Urea (HA film on urea surface, slow-release focus);
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?

The molten process (132-138℃) ensures uniform HA dispersion in urea matrix, avoiding nutrient segregation. It offers better stability, higher HA activity, and “slow-release + synergistic absorption” dual mechanisms, outperforming blended products.

5. Is Humic Acid Urea safe for crops and soil?

Yes, it is safe. Humic acid is a natural organic substance (extracted from mineral sources or bio-fermentation) that is non-toxic and biodegradable. Proper application will not cause crop burn or soil pollution; on the contrary, it can improve soil ecological environment.

6. How does it compare with controlled-release urea (CRU)?

Both have slow-release effects, but Humic Acid Urea has unique advantages:

It not only controls nitrogen release but also improves soil quality (CRU focuses only on nutrient slow release);
Lower cost than most CRUs;
Better compatibility with other fertilizers/pesticides;
Suitable for more soil types (especially degraded soils).

7. Its price is higher than conventional urea—Is it cost-effective?

Yes, it is highly cost-effective. Although the unit price is 15-25% higher, it can reduce dosage by 10-20% and topdressing times by 1-2 times (saving labor costs). Meanwhile, it increases crop yield by 8-17%, and the additional income far exceeds the price difference. The average ROI reaches 1:2.3 in grain crop cultivation.

8. When can I observe visible results?

Short-term (1-2 weeks): Crop leaves turn greener, seedlings grow stronger; Long-term (1-3 growing seasons): Yield increases by 8-17%, soil compaction/salinization alleviated, and drought/disease resistance enhanced.

9. Can it be mixed with other fertilizers or pesticides?

Yes. It is compatible with most NPK fertilizers, organic fertilizers, and pesticides. Avoid mixing with strong acidic/alkaline products (pH <5 or >9) to prevent nutrient loss. Test small batches first for large-scale mixing.

10. How to store Humic Acid Urea properly?

Store in a dry, well-ventilated, and cool area. Keep away from moisture, direct sunlight, and high temperatures (>30℃). Seal the package tightly after opening to prevent caking. Shelf life: 2 years under proper storage conditions.
