Urea is an organic compound that contains 46% nitrogen, making it one of the most concentrated nitrogen fertilizers available. It is produced synthetically from ammonia and carbon dioxide. Urea 46 Granules are granular, free-flowing substances that are easily handled and applied. Due to its high nitrogen content, it is particularly effective for various types of crops, including grains, fruits, and vegetables. Urea is a crucial component in promoting healthy plant growth, improving crop yield, and enhancing overall soil fertility.
Specifications
1. Chemical Formula: CO(NH2)2
2. Nutrient Content:
- Total Nitrogen (N): 46% (typically presented as 46-0-0)
- Other nutrients: Phosphorus (P), Potassium (K), and other micronutrients are not present in significant amounts.
3. Physical Properties:
- Form: Granular
- Color: White to slightly off-white
- Size: Granules typically range from 2 to 4 mm in diameter, though the distribution can vary depending on the manufacturer.
- Solubility: Highly soluble in water, making it easy to apply through various methods including broadcasting, fertigation, or incorporation into the soil.
4. Bulk Density: Approximately 0.7 to 0.8 g/cm�³ (varies by manufacturer and specific product).
5. Moisture Content: Typically less than 0.5% to 2% but varies by production process and storage conditions.
6. pH: Neutral to slightly alkaline (pH around 7).
7. Cation Exchange Capacity (CEC): Low inherent CEC, but nitrogen can influence the availability of other nutrients in the soil.
8. Storage: Store in a cool, dry place to prevent caking. Proper storage minimizes moisture uptake.
Application
- Method: Can be broadcast directly onto soil, banded with seeds or applied through irrigation systems (fertigation).
- Timing: Generally applied at planting or during the growing season, depending on crop requirements.
- Rate: The application rate will depend on soil tests, crop requirements, and local agricultural recommendations, typically ranging from 50 to 300 kg/ha.
Safety and Handling
While Urea is considered safe when handled properly, appropriate Personal Protective Equipment (PPE) such as gloves, masks, and safety goggles should be worn to prevent contact with skin and eyes. It is not classified as a hazardous material but can produce ammonia gas when exposed to moisture and heat.
