Wisconsin Mound Soil Absorption System and Area FillPractice Exam

When should tilling of the site occur?

1. When the soil is wet

2. When the soil is dry

3. Regardless of soil conditions

4. Only after heavy rain

The correct answer is: When the soil is dry

Tilling of the site should occur when the soil is dry because dry soil creates optimal conditions for tilling. When the soil is dry, it is less likely to become compacted and allows for improved aeration and mixing of organic materials, which enhances soil structure. Furthermore, tilling dry soil helps to minimize damage to the soil's aggregate structure and prevents clumping, which can occur when tilling wet soil. Wet soil tends to be sticky and can lead to poor tillage outcomes, such as the formation of clods that can hinder seed germination and root growth. Additionally, tilling under inappropriate conditions, such as when the soil is wet or immediately after heavy rain, may lead to soil erosion and degradation of soil quality. Therefore, selecting dry conditions for tilling promotes better soil management and improved overall site preparation.
