Which process primarily accelerates soil humification due to bioturbation?

💡 Explanation

Bioturbation by organisms increases soil porosity and mixes organic matter, accelerating humification via enhanced aeration and organic redistribution, because oxygen exposure promotes rapid decay. Therefore aeration is key, rather than soil compaction or mineral weathering.
