Which outcome results when earthworm limitations suppress bioturbation?

💡 Explanation

Reduced earthworm bioturbation decreases organic matter incorporation, because surface layers lose vital mixing, therefore accelerated surface nutrient depletion occurs, rather than deeper soil horizon impacts, due to only surface interactions that limit pedogenesis.
