Which risk commonly develops in heavily bioturbated soil horizons?

💡 Explanation

Increased bioturbation destabilizes soil structure due to burrowing animals disrupting cohesion via burrow network formation; therefore, this results in weaker soil susceptible to collapse, rather than increased clay surface, water infiltration, or directly altering soil pH.
