Explanation

### Step-by-Step Solution:

1. **Understanding the Compounds**:
- Urea (CO(NH2)2) is an organic compound, while ammonium sulfate ((NH4)2SO4) is an inorganic salt.

2. **Soil pH Impact**:
- Ammonium sulfate, when used as a fertilizer, can lead to the formation of acids in the soil. This is because it releases ammonium ions (NH4+) which can lower the pH of the soil, making it more acidic.
