Why should wet soil be avoided in pest management?

Avoiding wet soil in pest management is crucial because wet conditions can lead to soil compaction, which compresses the soil structure and inhibits healthy root growth. Compacted soil creates a conducive environment for certain pests and diseases to thrive, as they may spread more easily in moist conditions. Additionally, excess moisture can attract insects and other pests that flourish in wet environments, increasing the likelihood of infestations.

While the other options mention aspects of soil fertility, plant growth, and irrigation, they do not directly address the risks associated with pest management in wet soils. Wet soil can indeed be fertile, and moisture is essential for plant growth, but these factors do not mitigate the challenges posed by increased pest activity and soil health issues caused by compaction. Therefore, avoiding wet soil is pivotal in implementing effective pest management strategies.
