Urea fertiliser is a widely used nitrogen fertiliser in agriculture. It is a highly concentrated nitrogenous fertiliser containing about 46% nitrogen, making it the highest nitrogen content solid nitrogen fertiliser available.
Usage and Application
Soil Application:
Broadcasting: Urea can be evenly spread across the soil surface. It is advisable to incorporate urea into the soil immediately after application to minimize nitrogen loss due to volatilization.
Banding: Placing urea in bands near the plant roots can improve nitrogen use efficiency.
Drilling: Urea can be drilled into the soil alongside seeds at planting.
Foliar Application:
Spraying: Urea can be dissolved in water and sprayed onto the foliage of plants. This method is useful for providing a quick nitrogen boost during critical growth stages.
Irrigation:
Fertigation: Urea can be dissolved and applied through irrigation systems, ensuring an even distribution of nitrogen.
