Product Description

Product Introduction

 

DAP (Diammonium Phosphate) is a white crystalline or powdery compound widely recognized for its high nutrient content. It is a key agricultural fertilizer and industrial raw material, formed through the reaction of ammonia and phosphoric acid. This compound is valued for its ability to deliver two essential plant nutrients in a single formulation, making it efficient and versatile in various applications.

Product Application

Agricultural Applications

• Fertilization: DAP is a primary source of nitrogen and phosphorus for crops. Nitrogen supports leafy growth and photosynthesis, while phosphorus promotes root development, flowering, and fruit formation. It is commonly used in fields, orchards, and nurseries for crops like corn, wheat, soybeans, and vegetables. For example, in rice cultivation, DAP helps strengthen seedling roots and improve grain filling, leading to higher yields.
• Soil Enrichment: It acts as a soil amendment to enhance fertility, especially in acidic or nutrient-deficient soils. By releasing nutrients gradually, DAP improves soil structure and supports beneficial microbial activity, creating a healthier growing environment for plants.

Industrial Applications

• Flame Retardant Production: DAP is used as a raw material in manufacturing flame-retardant chemicals for plastics, textiles, and construction materials. Its chemical properties help inhibit fire spread, making it an essential component in fire-safe industrial products.
• Water Treatment and Chemical Synthesis: In some water management systems, DAP can regulate nutrient levels to control algae growth and prevent water eutrophication. Additionally, it serves as an intermediate in synthesizing certain phosphorous-based chemicals for pharmaceuticals and detergents.
