Liquid urea, such as Nano urea, is primarily used as a foliar spray to provide nitrogen nutrition directly to crops during their active growth phases. This method allows for quick absorption by the leaves.
Based on the provided information for Nano urea (4% N), here is a guide on its application:
Application Guide for Nano Urea
Using Nano urea involves specific steps for mixing and application to ensure effective nutrient delivery to your crops.
Dosage and Mixing
The recommended dosage involves diluting the concentrated liquid urea product with water before application.
- Mixing Ratio: Mix 2-4 ml of Nano urea in one Litre of water.
- Quantity per Acre: In general, a 500 mL quantity of Nano urea is sufficient for spraying one acre of land when prepared using the specified mixing ratio.
It's important to prepare the solution according to these concentrations to avoid potential leaf burn or inadequate nutrient supply.
Application Method and Timing
The liquid urea mixture is applied directly onto the leaves of the crop.
- Method: Spray the diluted Nano urea solution on the crop leaves.
- Timing: Apply the spray during the crop's active growth stages. This is when the plants are most actively developing leaves and require nitrogen for growth. Specific timing may depend on the crop type and its growth cycle.
Suitable Sprayers
Various types of sprayers can be used for applying the Nano urea solution uniformly across the crop canopy.
- Types: Suitable equipment includes:
- Knapsack sprayer
- Boom sprayer
- Power sprayer
- Drone sprayers
Ensuring good coverage of the leaf surface is key for effective absorption of the nutrient. Always calibrate your sprayer to ensure the correct application rate per acre.
In Summary:
To use Nano urea effectively:
- Dilute 2-4 ml of Nano urea per litre of water.
- Use approximately 500 mL of Nano urea (diluted as above) to cover one acre.
- Spray the solution directly onto crop leaves.
- Apply during the crop's active growth stages.
- Use appropriate spraying equipment like knapsack, boom, power, or drone sprayers.
This method ensures efficient delivery of nitrogen, supporting healthy crop development.
