Buy DAP Fertilizer (18-46-0) | Trusted Wholesale Supplier & Manufacturer | IGSAS

In the world of modern agriculture, few products are as fundamental and effective as DAP fertilizer, also known as Diammonium Phosphate. It’s the most widely used phosphorus (P) fertilizer globally, and for good reason. DAP is a high-nutrient, highly effective fertilizer that provides crops with a critical boost right at the start of their life cycle .

At IGSAS, we understand that the foundation of a successful harvest is laid early. DAP’s exceptional physical properties and high nutrient content make it the go-to choice for farmers looking to maximize their yields. But what exactly is it? DAP is an inorganic compound created by reacting phosphoric acid with ammonia, resulting in a granular, water-soluble fertilizer . It’s celebrated for its two primary macronutrients: Nitrogen (N) and Phosphorus (P).

Key Information: DAP 18-46-0

The power of DAP lies in its “18-46-0” formula, which represents its guaranteed analysis:

18% Nitrogen (N): Nitrogen is essential for leafy, vegetative growth. The nitrogen in DAP is in the ammoniacal form, which plants can readily absorb, giving them a strong start .
46% Phosphorus (P2O5): This is the star of the show. With 46% available phosphorus, DAP is a powerhouse for root development and energy transfer. This nutrient is crucial for flowering, seed formation, and overall plant health. DAP is the single most important source of this vital nutrient .
0% Potassium (K): DAP is a starter fertilizer; it focuses on delivering nitrogen and phosphorus where they’re needed most.

Diammonium Phosphate is suitable for all crops and soils, making it a versatile tool for any farming operation .

Technical Details

Dap Fertilizer

For the science-minded farmer and professional, understanding the technical specifications is key. DAP is a highly concentrated and efficient fertilizer, meaning less product is needed to deliver more nutrients, reducing storage and transport costs .

The technical specifications for premium-grade DAP are as follows:

Appearance: Brown, dark brown, or pale yellow free-flowing granules of uniform size .
Total Nutrient Content (N+P2O5): Minimum 64% .
Total Nitrogen (N): Minimum 18% .
Ammoniacal Nitrogen: Minimum 15.5% .
Available Phosphorus (P2O5): Minimum 46% .
Water-Soluble Phosphorus: Minimum 41%, making it highly available to plants .
Moisture Content: Maximum 2.5% .
Particle Size: 90% of the granules typically fall between 1.00mm and 4.00mm .
pH in 1% Solution: Approximately 8.0, creating a slightly alkaline environment in the soil near the granule.

Purity, Testing & Quality Assurance

At IGSAS, we know that quality is non-negotiable. DAP fertilizers need to be consistent and pure to deliver the promised agronomic benefits. Our product complies with the highest international quality standards, including the Chinese GB/T10205-2009 standard for premium (Grade A) product . We ensure:

High Water Solubility: Our DAP is highly water-soluble, allowing nutrients to dissolve and become available to the plant roots quickly .
Low Cadmium Content: We prioritize products with low levels of heavy metals. DAP typically contains very low cadmium levels, which is an environmental and health consideration .
Physical Integrity: The granules are strong, hard, and uniform, which is crucial for storage and mechanical application. This non-hygroscopic (doesn’t absorb moisture easily) property ensures it doesn’t clump, making it ideal for drill sowing .

Packaging Information

We offer flexible packaging solutions to meet the diverse needs of our customers. Our standard DAP packaging includes:

50 kg Bags: The industry standard for easy handling and application.
Jumbo / Big Bags (1000 kg / 1 MT): Ideal for large-scale farmers and distributors looking to reduce packaging costs and handling time .

Request the Current COA

We believe in full transparency. A Certificate of Analysis (COA) is a document that certifies the exact quality and purity of a specific batch of DAP fertilizer. It details the exact nutrient content, moisture levels, and other physical properties.

Common Research Applications Include

DAP is the preferred choice for establishing a healthy crop. Common applications include:

Basal Fertilization: It is the primary fertilizer applied during soil preparation and at the time of sowing for strategic cereal crops like wheat, barley, corn, and oats .
Root Development: DAP’s high phosphorus content is crucial for supporting root nodule formation in pulse crops like chickpeas, lentils, and beans .
Industrial Crops: It’s also used for pre-sowing soil prep for cotton, sunflower, and sugar beet .
Starter Fertilizer: DAP is an ideal choice for providing a quick boost of energy to young plants, ensuring they grow strong and deep root systems even in acidic soils .

H3: Precautions

While DAP is an excellent fertilizer, it must be handled with care. Here are key safety and handling precautions to follow.

Handling and Storage

DAP is stable under normal conditions but should be stored properly. Keep it in a cool, dry, and well-ventilated area away from direct sunlight, rain, and extreme heat . Since it can absorb moisture from the air (hygroscopic), ensure the storage area is clean and dry to prevent clumping . Do not store near food, seeds, or feed, as it can affect germination .

Incompatible Materials

DAP is incompatible with alkaline materials . It should never be mixed with lime, calcium-based products, or superphosphate-based products, as this can cause chemical reactions that release ammonia gas . It may also be corrosive to certain metals like iron, mild steel, aluminum, zinc, and copper .

Personal Protective Equipment (PPE)

When handling DAP, especially in dusty conditions, wear appropriate PPE . This includes:

Respiratory Protection: Use a NIOSH-approved dust respirator to avoid inhaling dust .
Eye Protection: Wear safety goggles to protect against eye irritation .
Hand Protection: Use cloth, leather, or PVC gloves .
Clothing: Wear long-sleeved clothing to protect your skin.

First Aid Measures

Eyes: Flush immediately with plenty of water for at least 15 minutes. If irritation persists, seek medical attention .
Skin: Wash with mild soap and water. Remove contaminated clothing .
Inhalation: Move to fresh air. If respiratory symptoms develop, seek medical attention .
Ingestion: If large amounts are swallowed, seek emergency medical attention immediately .
