Single-Source Blended NPK
Terafon® Single-Source Blended NPK fertilizers are produced through a precise mechanical blending process using high-purity straight fertilizers such as Urea, DAP/MAP, and MOP/SOP. These blends offer flexible NPK formulations, predictable nutrient performance, and cost-efficient production for large-scale agriculture.
This product class is widely used in global fertilizer supply chains due to its formulation versatility, rapid customization capability, and strong compatibility with secondary nutrients and micronutrient packs. Ideal for crops requiring tailored nutrient ratios, bulk application efficiency, and economical soil fertility management.

Key Features & Agronomic Advantages
-
Flexible NPK Formulation: Customizable NPK ratios to match specific crop requirements, soil test data, and regional nutritional standards.
-
Cost-Efficient Production: Produced from widely available straight fertilizers, reducing manufacturing cost, energy use, and capital expenditure.
-
Superior Logistics & Supply Chain Efficiency: High-analysis straight materials minimize transportation cost per nutrient unit and ensure consistent year-round supply.
-
Rapid Market Response: Blends can be produced quickly to meet seasonal demand, crop-stage requirements, or customer-specific formulas.
-
Even Granule Size for Better Distribution: Matched particle size (typically 2–4 mm) minimizes segregation and ensures uniform spreading in the field.
-
Additive Compatibility: Blends can incorporate secondary and micronutrients when physical/chemical compatibility is confirmed.
- Improved Nutrient Use Efficiency: Accurate blending ensures predictable nutrient availability and consistent field performance.
Recommended Applications
- Field Crops & Cereals: Wheat, maize, rice, soybeans—bulk field application with balanced NPK ratios.
- Vegetables & Cash Crops: Open-field vegetables, potatoes, cotton, sugarcane—custom NPK for crop-specific needs.
- Orchards & Plantations: Pre-plant and top-dress blends for citrus, apples, bananas, coffee, etc.
- Greenhouse & Nursery Crops: Small-batch specialty blends with micronutrients.
- General Soil Fertility Improvement: Ideal for farms requiring economical, flexible nutrient programs.
Application Guidelines
-
Use soil analysis to determine nutrient requirements before selecting an NPK ratio.
-
Suitable for broadcasting, banding, top-dressing, or soil incorporation.
-
Apply with calibrated spreaders to ensure even nutrient distribution.
-
For high-value crops, blending can be supplemented with targeted micronutrient applications.
-
Avoid excessive handling to minimize segregation in the final blend.
- Do not store blends with highly hygroscopic materials unless properly coated or protected.
Packaging & Storage
-
Packaging: 25 kg / 50 kg woven PP bags, 500–1,000 kg jumbo bags
-
Storage: Store in a cool, dry, ventilated warehouse; protect from moisture and direct sunlight
-
Shelf Life: Stable under proper storage; anti-caking treated for long-term handling
