Скачать или смотреть Use of Calcium Ammonium Nitrate in Wheat Crop||Ghulam Shabeer Velogs

Calcium Ammonium Nitrate (CAN) is a popular nitrogen-based fertilizer used in wheat cultivation due to its balanced composition of ammonium nitrogen (NH₄⁺) and nitrate nitrogen (NO₃⁻). Here's how it benefits wheat crops and guidelines for its application:

Benefits of CAN in Wheat Cultivation

1. Improved Nitrogen Availability:

CAN contains 27-28% nitrogen, half as ammonium nitrogen and half as nitrate nitrogen.

Nitrate nitrogen is readily available to plants, promoting quick growth, while ammonium nitrogen is slowly released, ensuring sustained nutrient supply.



2. Better Root Development:

The presence of calcium in CAN enhances soil structure and root penetration, improving overall crop health.



3. Resistance to Lodging:

Calcium strengthens plant cell walls, making wheat plants more resistant to lodging caused by strong winds or heavy rains.



4. pH Neutral:

CAN is less acidic than urea or ammonium sulfate, minimizing the risk of soil acidification over time.



5. Ideal for Moisture Deficit Areas:

CAN’s nitrate nitrogen is less prone to volatilization, making it suitable for areas with lower rainfall.




Application Guidelines

1. Soil Testing:

Conduct a soil test to determine nitrogen requirements for your wheat crop.



2. Timing:

First Dose: Apply at the time of sowing as a basal dose.

Second Dose: Top-dress at the tillering stage (25-30 days after sowing).

Third Dose: Apply at the booting stage (45-50 days after sowing) if required.



3. Dosage:

Typically, 50-100 kg/acre of CAN is applied, depending on the soil fertility and crop requirements.



4. Method of Application:

Broadcasting: Spread evenly over the field for uniform nutrient distribution.

Furrow Placement: Place the fertilizer near the root zone for better absorption.



5. Irrigation:

Water the field after applying CAN to ensure proper nutrient uptake and to reduce nitrogen losses.




Precautions

Avoid over-application as excessive nitrogen can lead to lush vegetative growth and reduce grain yield.

Store CAN in a dry place to prevent caking.

Mix CAN with other fertilizers only if compatibility is assured.


Using CAN effectively in wheat production enhances yield and ensures optimal grain quality.
