Which pedogenic effect is accelerated when earthworm bioturbation increases?

💡 Explanation

Intense earthworm activity accelerates clay mineral translocation because bioturbation increases mixing of soil horizons, therefore enhancing eluviation of clay particles. This increases clay minerals movement, rather than the weathering reduction or aggregate stabilization implied by the other options.
