Difference B/W CAN and Urea Fertilizer |Cyber Agri Extension| Best Usage of Calcium Ammonium Nitrate

Urea and calcium ammonium nitrate (CAN) are both nitrogenous fertilizers commonly used in agriculture to provide plants with essential nitrogen nutrients. While they serve similar purposes, there are key differences between them:
Chemical Composition:
Urea: Urea is a white, crystalline solid containing about 46% nitrogen. It is a synthetic organic compound produced from ammonia and carbon dioxide.
Calcium Ammonium Nitrate (CAN): CAN is a granular fertilizer containing approximately 27% nitrogen. It is a combination of ammonium nitrate and calcium carbonate or calcium oxide.
Nitrogen Release:
Urea: Urea undergoes hydrolysis in the soil, converting into ammonium and bicarbonate ions. This process requires the enzyme urease and soil moisture. Ammonium is then converted to nitrate by soil microorganisms in a process called nitrification. This slow-release nature makes urea suitable for long-term nitrogen supply.
CAN: CAN dissolves readily in water, releasing both ammonium and nitrate ions immediately upon application. This makes CAN a quick-release nitrogen fertilizer, providing an immediate nutrient supply to plants.
pH Impact:
Urea: Urea has a slightly acidic reaction in the soil upon hydrolysis, which can lower soil pH over time.
CAN: CAN contains calcium carbonate or calcium oxide, which can help neutralize soil acidity, making it a suitable choice for acidic soils.
Best Way of Usage:
Urea:
Application: Urea can be broadcast on the soil surface or incorporated into the soil.
Timing: It is best applied before planting or as a topdressing during the growing season, especially for crops with high nitrogen demands.
Placement: Urea should be incorporated into the soil or irrigated immediately after application to minimize nitrogen losses through volatilization.
Calcium Ammonium Nitrate (CAN):
Application: CAN is typically broadcast on the soil surface or applied through fertigation systems.
Timing: It can be applied at various growth stages of the crop, depending on the nutrient requirements.
Placement: CAN should be applied evenly across the field and watered in to ensure proper nutrient distribution and minimize losses.
It's important to consider factors such as soil type, crop requirements, environmental conditions, and regulations when deciding between urea and CAN and determining the best application method for optimal crop growth and nitrogen utilization while minimizing environmental impact. Additionally, it's advisable to conduct soil tests to determine the nutrient needs of the crops and adjust fertilizer application rates accordingly.

Sugarcane main flod karni chaheay ya ni or gany ki fasal main is k kia benefits hain?

[@CyberAgriExtension]

Is main 2 Tarah ki nitrogen ha, akbAmmonical or dosri Nitrate, Jo k podo asani se jazab krleta ha. isk elawa is main calcium or Magnesium b ha, jo cell wall ko mazbot banta ha or sabz mady ko b barata ha. Is se podon main bemari or pest k khilaf quwaty madafat b paida hoti ha.

ایک بیگ فی ایکڑ ایک وقت میں کافی ہوتا ہے اس کے بعد ضرورت کے مطابق ڈالنا چاہیے-
