UREA 46 FERTILIZER

Urea 46 (Urea Fertilizer 46-0-0)

Urea 46, commonly referred to as Urea 46-0-0, is a widely used nitrogen-based fertilizer in agriculture. It contains 46% nitrogen by weight, making it one of the most concentrated solid nitrogen fertilizers available. Here’s a detailed description:

Key Characteristics:

• Chemical Composition: Primarily urea (CO(NH₂)₂), a white, granular or prilled (small, spherical pellets) substance. The “46” indicates 46% elemental nitrogen content, with no phosphorus (0) or potassium (0).
• Appearance: White or off-white granules, typically 2-4 mm in diameter for easy handling and spreading.
• Solubility: Highly soluble in water (about 1079 g/L at 20°C), which allows for quick dissolution and absorption by plants.
• Production: Manufactured through the reaction of ammonia and carbon dioxide under high pressure and temperature, resulting in a cost-effective product.

Uses:

• Primary Application: Provides essential nitrogen for plant growth, promoting leafy development, photosynthesis, and overall yield. Suitable for a wide range of crops, including cereals (wheat, rice, corn), vegetables, fruits, and pastures.
• Application Methods:
  • Soil broadcasting before planting or top-dressing during growth.
  • Foliar spraying (dissolved in water) for rapid uptake.
  • Incorporation into irrigation systems (fertigation).
• Soil Types: Effective in most soils but performs best in neutral to slightly acidic conditions (pH 6-7). Avoid over-application to prevent nitrogen leaching or volatilization (loss as ammonia gas).
