Diammonium Phosphate (DAP) fertilizer is a high-grade complex chemical fertilizer widely used in modern agriculture across developed nations worldwide.
This fertilizer is recognized as environmentally friendly and delivers proven positive impacts on crop performance and yield.
Competitive Advantages of DAP Dinh Vu
Prior to the commissioning of the DAP Dinh Vu chemical fertilizer plant in 2009, domestic agricultural demand for DAP fertilizer was completely dependent on foreign imports (primarily from China) at substantial foreign exchange costs.
Since entering commercial operation, DAP Dinh Vu Plant has manufactured and supplied approximately 3 million metric tons of high-grade DAP fertilizer to the market. Dinh Vu DAP fertilizer products are distributed across all 63 provinces and centrally-run cities nationwide, and exported to international markets including Japan, South Korea, the Philippines, Indonesia, New Zealand, Cambodia, and India.
DAP Dinh Vu fertilizer contains 45% phosphate (P2O5) and 16% pure nitrogen (N), along with various essential secondary nutrients and micronutrients. Economic calculations indicate that DAP provides concentrated macro-nutrients, with total pure nitrogen and phosphate nutritional content reaching 61%. 1 kg of DAP equals 2.8 kg of single superphosphate plus 0.34 kg of urea fertilizer. Consequently, utilizing complex DAP fertilizer significantly reduces farmer labor: instead of applying 25 kg of base NPK fertilizer, farmers only require 6 kg of DAP, thereby providing highly assimilable phosphorus and nitrogen for crops.
Field surveys and research indicate that, due to the unique characteristics of Lao Cai apatite rock ore in Vietnam, DAP Dinh Vu possesses natural slow-release properties and exceptional nutrient uptake efficiency. On identical soil types and crop varieties, farmers only need to apply 80% to 90% of the volume required by conventional fertilizers (calculated on equivalent nutrient ratios), while producing robust, sturdy crops with enhanced pest resistance and decreased pesticide requirements.
This is readily explained by the controlled nutrient release rate: macro-nutrients are supplied proportionally and continuously across plant vegetative stages, creating sturdy root systems and stalks that prevent lodging and bolster crop vigor, while minimizing leaching and run-off nutrient losses.
The adoption of slow-release fertilizers aligns with international agricultural best practices, matching fertilizer solubility curves to crop vegetative cycles, avoiding waste from volatilization and surface run-off, and preserving soil ecology and water resources. Deep placement fertilization techniques are particularly essential for phosphate fertilizers, including high-grade DAP complex fertilizer.
This advanced chemical technology safeguards nutrient integrity, minimizes leaching, and delivers steady yet timely nourishment throughout the crop development cycle. Deep placement substantially lowers application doses and reduces fertilizer expenditures in intensive farming. DAP Dinh Vu guarantees total nutrient content ≥ 61%, consisting of 16% Nitrogen and 45% P2O5 active phosphorus.
Enhancing Crop Resilience and Environmental Sustainability
As a balanced N-P complex fertilizer meeting rigorous international benchmarks, DAP Dinh Vu provides harmonious nutrition, fostering plant health, increasing stress resistance, and mitigating pesticide spraying requirements. This complies with clean agricultural production standards under VIETGAP, supporting the Government's policy to modernize Vietnamese agricultural production.
Being chemically neutral, DAP Dinh Vu poses no skin contact hazards for farmers and is suitable for all soil classifications and agricultural crops across Vietnam. DAP Dinh Vu is particularly effective as a basal fertilizer, supplying vital nitrogen and phosphorus right at seed germination and sprouting, enhancing winter cold tolerance. Northern spring-crop paddy rice applied with DAP Dinh Vu shows virtually no frost damage compared to standard phosphate fertilizers. For tea plantations in northern mountainous regions, DAP boosts winter flush productivity under adequate irrigation.
Owing to specialized chemical engineering processes, hazardous impurities and soil-hardening agents—particularly phosphogypsum (CaSO4·2H2O)—are thoroughly removed during manufacturing. Using DAP Dinh Vu therefore reduces freight volume, field handling labor, and eliminates environmental contaminants in farmland.
Manufactured on modern, automated chemical production lines with ISO-compliant quality management and VILAS-17025 certified testing laboratories, every phase—from raw apatite feed preparation, chemical reaction process control, through to final product testing—is rigorously monitored. DAP Dinh Vu consistently guarantees superior chemical and physical stability.
With these distinct advantages, DAP Dinh Vu has gained widespread trust among farmers nationwide. In 2023, DAP - Vinachem JSC targeted VND 3,243 billion in revenue, VND 115 billion in pre-tax profit, and 210,000 metric tons in DAP output. The company focuses all resources on operational optimization, strict environmental compliance, reliable raw material supply, and adaptive market distribution.
