NPK 15-15-15 (balanced blend)

Description

1. Product Overview

NPK 15-15-15 is a homogeneous, balanced compound fertilizer containing equal proportions of nitrogen, phosphorus, and potassium. It is primarily used as a base or maintenance fertilizer for permanent crops, row crops, and horticulture to support early vigor and root development. The key value proposition is predictable nutrient release and ease of bulk handling, reducing storage and application costs. Strategically, it remains the global benchmark for multi-nutrient baseline fertility programs, particularly in price-sensitive yet quality-driven agricultural markets.

2. Key Specifications & Technical Characteristics

• Chemical composition: N-P₂O₅-K₂O (15%-15%-15% by weight), chloride ≤ 2% (low-chloride grade available)

• Purity level: Industrial grade, heavy metal content compliant with EU/UK REACH and ISO 8157

• Physical characteristics: Granular (2–4 mm ≥ 90%), light grey to off-white, bulk density 0.9–1.0 g/cm³, free-flowing with anti-caking coating

• Packaging options: 50 kg woven PP/PE bags, 1,000 kg bulk bags, or loose bulk in container liners

• Shelf life: 24 months under dry, ventilated conditions (avoid direct sunlight)

3. Core Industrial Applications

• Primary industries: Large-scale arable farming (corn, wheat, rice), plantation crops (oil palm, rubber, tea), and commercial horticulture.

• Operational use cases: Pre-planting broadcast, side-dressing for perennial crops, and as a raw material for custom blended NPK formulations.

• Performance advantage: The precisely balanced ratio prevents luxury uptake of any single nutrient, reducing fertilizer waste by 12–18% compared to physical blends of single-nutrient fertilizers. Granule uniformity ensures excellent spreader calibration and minimized segregation during transport.

• Cost advantage: Low hygroscopicity extends practical storage windows in humid climates, lowering re-bagging or drying costs for distributors.

4. Competitive Advantages

• Quality consistency: Every batch tested at source and destination; guaranteed nutrient variance ≤ 0.5% absolute.

• Supply reliability: Multi-origin sourcing (EMEA, SE Asia, CIS) with 24/7 logistics coordination; typical lead time 15–25 days FOB to any major port.

• Logistics capability: Dedicated dry-bulk vessel loading and container-stuffing stations with weight certificate automation.

• Price competitiveness: Direct mill contracts remove 2–3 intermediary layers; volume-based rebates available.

• Sustainability: Zero added heavy metals; compatible with precision agriculture and variable-rate technology; reduced carbon footprint per nutrient unit vs. single-nutrient blends.

• Technical support: Full COA, SDS, and crop-specific application guides available via API or PDF upon purchase confirmation.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (bulk) or 1 full 20-ft container

• BULK 20MT loading capacity: 20 MT (net weight) per 20-ft dry bulk container or per truckload

• Loading capacity per container (standard 20-ft): 22 MT net (bagged) / 24 MT net (bulk liner)
