Question: Soil colloidal particles show the phenomena? (IFFCO 2022)
Options:
Urea
Anhydrous ammonia
Sodium nitrate
Ammonium sulphate
Urea has the highest nitrogen content among commonly used nitrogen fertilizers. It contains approximately 46% nitrogen by weight. This makes it a highly efficient and cost-effective source of nitrogen for plants.
📌 Other Options Explanations:
-Anhydrous ammonia: Contains around 82% nitrogen, the highest among nitrogen fertilizers. However, it's a gas and requires specialized equipment for storage and application, making it less practical for many farmers.
-Sodium nitrate: Contains approximately 16% nitrogen.
-Ammonium sulphate: Contains approximately 21% nitrogen. It also provides sulfur, which can be beneficial for some crops.
🔑Key Points:
-Urea is also known as Carbamide and its chemical formula is CO(NH2)2.
-Other names of Urea are-
-Carbamide
-Carbonyldiamide
-Diaminomethanone.
-Urea is the most important nitrogenous fertilizer in the country because of its high N content (46%N).
-Urea is neutral in pH and can adapt to almost all kinds of soils.
-The main function of Urea fertilizer is to provide the plants with nitrogen to promote green leafy growth.
