Description

High-Quality Agricultural DAP (Diammonium Phosphate)

Agricultural DAP (Diammonium Phosphate) is one of the most widely used compound fertilizers in global agriculture. It provides both nitrogen and phosphorus in a single product, supporting strong root development, improved crop growth, and higher yield performance. Manufactured in China by Shandong Aolansu, it delivers stable quality, high nutrient content, and reliable performance for modern farming.

Stable Nutrients & Fast Absorption

Our Agricultural DAP contains ≥64% total nutrients (N + P₂O₅), including nitrogen ≥18% and available phosphorus ≥46%, with a balanced nutrient ratio of about 1:2.5. Water-soluble phosphorus ≥90% ensures fast absorption by crops, while low moisture (≤2.0%) prevents caking and improves storage stability.

Advanced Manufacturing Process

Produced using high-purity phosphoric acid and liquid ammonia through chemical synthesis, granulation, drying, and screening. The product features uniform 2–4 mm granules with excellent flowability, making it suitable for mechanical spreading and manual application.

Wide Crop Application

Suitable for rice, wheat, corn, cotton, vegetables, oilseeds, and fruit trees such as apples, pears, and citrus. It performs well in acidic and neutral soils, improves root development, increases flowering and fruiting rate, and enhances crop quality and yield.

Packaging & Supply Ability

Standard packaging is 50 kg PP woven bags with PE liner, moisture-proof and durable for long-distance transport. We support 1 ton minimum trial orders, OEM packaging, and bulk supply with factory-direct pricing.

FAQ

Q1: What kind of soil is suitable for agricultural DAP?
A1: Our agricultural DAP is weakly alkaline, which is most suitable for neutral and acidic soils. It can slightly adjust the soil pH value, reduce the fixation of phosphorus by the soil, and improve the fertilizer utilization rate. It is not suitable for strong alkaline soils, which will easily lead to phosphorus fixation and reduce the fertilizer effect. Shandong Aolansu’s factory in China has tested the adaptability of the product in various soils, ensuring good application effect.

Q2: Can agricultural DAP be mixed with other fertilizers?
A2: It can be mixed with nitrogen fertilizers such as urea and ammonium nitrate, which can complement nutrients and improve the overall fertilizer effect. However, it should not be mixed with alkaline fertilizers such as plant ash and lime, because it will cause nutrient loss and affect the fertilizer effect. Shandong Aolansu will provide detailed mixing guidelines for free to help you use it correctly.

Q3: What are the advantages of purchasing agricultural DAP from your China supplier?
A3: Shandong Aolansu has its own factory in China, which can provide factory-direct prices, reducing your procurement costs. We have rich production experience and strict quality control, ensuring stable product quality and consistent fertilizer effect. We also provide sufficient stock, timely delivery and complete export documents, which can fully meet your bulk procurement needs.
