Urea is a better fertilizer than ammonium sulphate because `:`

Options

A. It has greater percentage of nitrogen
B. It is more soluble
C. It is weak basic
D. It does not produce acidity in soil

Answer

To answer the question "Urea is a better fertilizer than ammonium sulphate because:", we can break down the reasoning step by step.

### Step 1: Understanding the Composition of Urea and Ammonium Sulphate
- Urea (CO(NH2)2) is a nitrogenous compound that contains a high percentage of nitrogen.
- Ammonium sulphate ((NH4)2SO4) is also a nitrogenous fertilizer but has a lower percentage of nitrogen compared to urea.

### Step 2: Analyzing the Nitrogen Content
- Urea contains approximately 46-47% nitrogen by weight.
- Ammonium sulphate contains about 21% nitrogen by weight.

### Step 3: Solubility in Water
- Urea is highly soluble in water, which allows for better absorption by plants.
- Ammonium sulphate is also soluble but not as much as urea.

### Step 4: Environmental Impact
- When urea is applied, it breaks down into ammonia and then into nitrates, which are easily assimilated by plants.
- Ammonium sulphate releases ammonium ions, which can lead to soil acidification over time.

### Step 5: Conclusion
- Urea is considered a better fertilizer than ammonium sulphate primarily because it has a higher percentage of nitrogen (about 47% compared to 21% in ammonium sulphate), making it more efficient in providing the necessary nutrient for plant growth.

### Final Answer
Urea is a better fertilizer than ammonium sulphate because it has a greater percentage of nitrogen (approximately 47% by weight).
