Diammonium phosphate (DAP) fertilizer

Description

1. Product Overview

Diammonium phosphate (DAP) fertilizer is a high-efficiency, NPK 18-46-0 compound fertilizer widely adopted for direct soil application in row crops, cereals, and oilseeds. Its high phosphorus availability supports early root vigor and energy transfer, while nitrogen promotes vegetative growth. The key value proposition is superior nutrient concentration per ton, lowering freight and storage costs per hectare. In volatile commodity markets, DAP’s predictable dissolution and neutralization of soil acidity make it a critical asset for yield security and farm profitability.

2. Key Specifications & Technical Characteristics

• Chemical composition: (NH₄)₂HPO₄ – 18% N, 46% P₂O₅, <1.5% moisture

• Purity / grade: Technical-grade DAP (≥ 99% purity); fertilizer grade meets ISO 8157 standards

• Physical characteristics: Free-flowing brown or grey-brown granules, 90% between 2–4 mm, bulk density ~0.96 g/cm³, hardness >3 kgf

• Packaging options: 50 kg woven polypropylene bags with inner liner; 1,250 kg big bags; bulk in-container (liner bag optional)

• Shelf life: 24 months in dry, covered storage (<40% relative humidity, no direct sun)

3. Core Industrial Applications

• Primary industries: Large-scale row crop farming (corn, wheat, rice, soybeans); fruit & nut orchards; sugarcane and cotton production

• Operational use cases: Starter fertilizer banded 2–3 inches below seed; pre-plant broadcast incorporation; fertigation after dissolution in neutral water

• Performance advantage over alternatives: Higher P₂O₅ content per ton vs. MAP or single superphosphate; less soil acidification than urea-based blends; lower caking tendency compared to low-density phosphate sources

• Cost efficiency: 20–25% fewer tons required per hectare versus conventional 10-20-10 blends, reducing transport, handling, and application labor

4. Competitive Advantages

• Quality consistency: Each batch tested for particle size distribution, moisture, biuret, and heavy metals (ISO 17025-accredited lab)

• Supply reliability: Multi-plant production across geopolitically stable regions with dedicated B2B inventory buffers against disruptions

• Logistics capability: 24/7 dispatch scheduling; direct rail-to-port and container stuffing; shipment tracking via digital logistics portal

• Price competitiveness: Long-term take-or-pay contracts with 2–5% spot discounts for full-haul shipments (≥500 MT)

• Sustainability: Low cadmium (<10 ppm); adherence to EU Fertilizing Products Regulation 2019/1009; compatible with precision application reducing runoff potential

• Technical support: Free crop-nutrient modeling; MSDS, batch COA, and phytotoxicity risk reports provided pre-shipment

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (one bulk truckload or partial container)

• Bulk 20 MT minimum for blended packaging

• Loading capacity per 20′ dry container: 25–27 MT (depending on bag type / bulk liner)

• Loading capacity per 40′ dry container: 26–28 MT bulk; 24–25 MT palletized bags
