Question: 1 / 400

What can occur if trenches are dug while soil is wet?

Increased absorption capacity

Smearing and potential irreversible damage to soil structure

When trenches are dug in wet soil, smearing occurs as the soil particles become disrupted and slick, which can lead to potential irreversible damage to the soil structure. Wet soil is less stable and more prone to compaction, which can create a dense, impermeable layer that hampers water movement and root penetration. This alteration can negatively impact overall soil health and soil's ability to support vegetation and structures above.

In contrast, increased absorption capacity, enhanced drainage performance, and faster installation processes are not typical outcomes of digging trenches in wet soil. Instead of benefiting from these effects, the structural integrity and characteristics of the soil are compromised, making it crucial to evaluate soil moisture conditions before excavation work.
