Which one of these would you consider to be an artificial method of replenishing nutrients in the soil?

Options

A. Addition of fertilizers
B. Mixed cropping
C. Crop rotation
D. Fallowing

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for an artificial method of replenishing nutrients in the soil. We need to differentiate between artificial and natural methods.

2. **Identifying the Options**: The options provided are:
- Adding of fertilizers
- Mixed cropping
- Crop rotation
- Fallowing

3. **Analyzing Each Option**:
- **Adding of Fertilizers**: This involves the application of chemical substances to the soil to provide essential nutrients. Since fertilizers are manufactured in factories and deliberately added to the soil, this method is considered artificial.
- **Mixed Cropping**: This method involves planting multiple crops simultaneously on the same piece of land. It is a natural method of utilizing the soil's nutrients but does not specifically replenish them artificially.
- **Crop Rotation**: This practice involves changing the type of crop grown in a particular area in different seasons. While it helps maintain soil health, it is a natural method of nutrient management.
- **Fallowing**: This is the practice of leaving land uncultivated for a period to allow it to recover and replenish its nutrients naturally. It is not an artificial method.

4. **Conclusion**: Among the options, the only artificial method of replenishing nutrients in the soil is the **Adding of Fertilizers**.

**Final Answer**: Adding of fertilizers.
