Which of the following is a benefit of practicing crop rotation?

Practicing crop rotation offers significant benefits, particularly in improving soil health and agricultural yields. By alternating the types of crops planted in a given area across seasons, the practice helps break the cycles of pests and diseases that often develop when the same crop is grown repeatedly. Different plants contribute various nutrients to the soil; for example, legumes can add nitrogen, which enhances soil fertility. This diversity in planting not only enriches the soil but also enhances its structure and ability to retain moisture, leading to healthier crops and ultimately higher agricultural yields.

In contrast, other options highlight negative aspects that are typically avoided through proper crop rotation. Increased pest infestations would occur with monoculture practices, where the same crop is planted year after year. Decreased soil nutrients would also result from this practice, as certain crops can deplete specific nutrients from the soil without replenishing them. Lastly, higher usage of chemical fertilizers contradicts the goal of sustainable agriculture, where crop rotation aims to reduce reliance on such inputs by naturally enhancing soil nutrient levels. Thus, choosing to implement crop rotation leads to improved soil health and enhanced agricultural productivity.
