Which consequence results when excessive earthworm activity impacts agricultural topsoil?

💡 Explanation

Decreased soil aggregate stability occurs when excess bioturbation physically breaks down soil structure because earthworm castings have lower structural integrity; therefore topsoil becomes more vulnerable erosion, rather than benefiting seedling emergence or speeding pesticide breakdown.
