Which cultural practice can support healthy plant growth?

Using crop rotation as a cultural practice is effective in supporting healthy plant growth because it helps to maintain soil fertility and prevents the buildup of pests and diseases. By alternating the types of crops grown in a specific area, different nutrient needs and pest pressures are addressed, reducing the chances of soil depletion that can occur when the same crops are grown repeatedly in the same spot. This practice allows for a more diverse soil ecosystem, promotes nutrient cycling, and can disrupt the life cycles of pests that may thrive on a single crop type, ultimately leading to healthier plants.

In contrast, the other practices listed do not contribute to healthy plant growth. Planting the same crops in the same location repeatedly can lead to nutrient depletion and increased vulnerability to diseases. Using the same fertilizer type without considering the varying nutrient needs of different plants can lead to imbalances in soil chemistry. Overwatering plants can cause root rot and other water-related issues, which negatively impact plant health. Therefore, crop rotation stands out as the most beneficial practice for sustainable plant growth.
