What is the goal of crop rotation?

The goal of crop rotation is to enhance soil nutrients, which is achieved through the systematic planting of different crops in the same area across a sequence of seasons. This practice helps to improve soil fertility and structure over time. Different plants have varying nutrient requirements; rotating crops allows for the replenishment of nutrients that may have been depleted by certain plants during a growth cycle. For instance, legumes might be planted in rotation because they can fix atmospheric nitrogen, enriching the soil for subsequent crops.

In addition to nutrient enhancement, crop rotation also helps to disrupt the cycles of pests and diseases, as many pests tend to specialize on certain species of plants. By changing crop types, farmers can reduce pest populations naturally over time. However, the specific goal emphasized here is the enhancement of soil nutrients, making it the correct choice.
