NPK Roller Granule Fertilizer is a compound fertilizer produced through roller compaction or roller granulation technology. This process forms dense, uniform granules without high-temperature drying, making it suitable for producing balanced nutrient fertilizers with stable physical properties.
For agricultural markets such as Vietnam—where rice, vegetables, fruit trees, and industrial crops are widely cultivated—NPK roller granule fertilizer is commonly used due to its ease of application, consistent nutrient distribution, and adaptability to both manual and mechanical fertilization.
Hebei Wangdalei Trading Co., LTD supplies NPK roller granule fertilizers from China to Vietnam, supporting distributors, importers, and agricultural input companies with stable formulations and export-oriented packaging.
Roller granulation differs from traditional drum or tower granulation methods. The process relies on mechanical pressure rather than thermal bonding, which allows better control of nutrient ratios and granule hardness.
Key technical characteristics include:
Uniform granule size, typically 2–4 mm
Low moisture content, reducing caking during storage
Balanced nutrient distribution in each granule
Reduced nutrient loss during production
Suitable for chloride-based and low-chloride formulations
These characteristics are especially relevant for Vietnam’s humid climate, where fertilizer storage stability and transportation durability are critical factors.
Vietnamese agriculture requires fertilizers adapted to diverse crops and soil conditions. NPK roller granule fertilizers are often customized according to regional nutrient demand.
| Crop Type | Common NPK Ratio | Application Stage |
|---|---|---|
| Rice | 16-16-8 / 20-20-15 | Basal and tillering |
| Vegetables | 15-15-15 / 18-18-18 | Pre-plant and top dressing |
| Fruit Trees | 12-12-17 / 15-10-20 | Flowering and fruit setting |
| Coffee & Pepper | 16-8-16 / 20-10-10 | Growth and yield stages |
| Industrial Crops | Customized | Based on soil analysis |
Roller granule NPK fertilizers are compatible with blended micronutrients such as magnesium, sulfur, or trace elements when required by local agronomic practices.
Vietnam’s agricultural systems range from smallholder farms to large plantations. NPK roller granule fertilizer is suitable for both due to its physical and chemical stability.
Practical advantages include:
Easy broadcasting by hand or machine
Reduced dust compared with powder fertilizers
Even nutrient release in soil
Good compatibility with compound fertilization programs
Lower risk of segregation during transport
In paddy fields and upland farming systems alike, roller granule fertilizers help maintain consistent crop nutrition throughout critical growth stages.
As an NPK roller granule fertilizer supplier from China, Hebei Wangdalei Trading Co., LTD works with production facilities that follow standardized manufacturing and inspection procedures.
Quality control focuses on:
Nutrient content accuracy
Granule strength and uniformity
Moisture level control
Anti-caking performance
Packaging integrity for export
Each batch is tested to ensure it meets contractual specifications required by Vietnamese import regulations and distributor standards.
Given Vietnam’s climate and port handling conditions, export packaging plays an important role in fertilizer quality preservation.
Typical export options include:
25 kg or 50 kg PP woven bags with inner liner
Moisture-resistant packaging for sea freight
Neutral or customer-specified labeling
Containerized or bulk pallet loading
Hebei Wangdalei Trading Co., LTD supports flexible logistics arrangements to meet the needs of Vietnamese wholesalers and agricultural supply chains.
Granule strength is a key performance indicator for roller granule fertilizers. Adequate hardness reduces breakage during transportation while still allowing granules to dissolve gradually in soil.
From a technical perspective:
Higher compaction pressure improves granule integrity
Balanced binder ratios reduce dust formation
Controlled particle size enhances nutrient uniformity
Proper cooling and screening reduce fines
These factors contribute to stable fertilizer performance under Vietnam’s field and storage conditions.
Q1: Is NPK roller granule fertilizer suitable for mechanized spreading?
Yes. The uniform granule size makes it compatible with most fertilizer spreaders used in Vietnam.
Q2: Can formulations be customized for specific crops?
Formulations can be adjusted according to crop type, soil conditions, and local agronomic recommendations.
Q3: How does roller granulation affect nutrient availability?
Roller granulation ensures even nutrient distribution within each granule, supporting consistent nutrient uptake by crops.
Q4: What is the typical shelf life of NPK roller granule fertilizer?
When stored in dry conditions, shelf life generally ranges from 24 to 36 months.
Q5: Can micronutrients be added during production?
Yes. Micronutrients such as boron, zinc, or magnesium can be incorporated if required.
NPK Roller Granule Fertilizer plays a practical role in supporting Vietnam’s diverse agricultural production systems. Its stable granule structure, adaptable formulations, and suitability for both small-scale and commercial farming make it a widely used compound fertilizer option.
As a supplier focused on export markets, Hebei Wangdalei Trading Co., LTD provides NPK roller granule fertilizers from China with consistent quality, flexible specifications, and packaging adapted to Vietnam’s agricultural and logistical requirements.
