Crop rotation is helpful because

Options

A. It gives more nitrates in the soil
B. It gives more sulfates in the soil
C. It gives more nitrogen in the soil
D. It gives more phosphorus in the soil

Explanation

**Step-by-Step Solution:**

1. **Understanding Crop Rotation**: Crop rotation is an agricultural practice where different types of crops are planted in the same area in sequential seasons. This method prevents the continuous planting of the same crop, which can deplete specific nutrients in the soil.

2. **Nutrient Management**: Different crops have varying nutrient requirements and uptake patterns. By rotating crops, farmers can improve soil health by allowing different plants to contribute to and utilize different nutrients. For example, legumes can fix nitrogen in the soil, enhancing nitrogen availability for subsequent crops.

3. **Soil Fertility Improvement**: The practice of crop rotation leads to an increase in soil fertility. As different crops are planted, they can replenish nutrients such as nitrogen, phosphorus, and sulfur, which are essential for plant growth.

4. **Increased Crop Yield**: With improved soil fertility, the overall health of the soil is enhanced, leading to better crop yields. Healthy soil supports robust plant growth, which can result in higher production levels.

5. **Conclusion**: Therefore, crop rotation is helpful because it increases the availability of essential nutrients like nitrates, enhances soil fertility, and ultimately leads to increased crop yields.

**Final Answer**: Crop rotation is helpful because it increases the availability of nitrates in the soil, which improves soil fertility and crop yield.
