Which mechanism accelerates soil horizon mixing in grasslands?

💡 Explanation

Bioturbation, involving soil displacement via organisms, mixes soil layers, because tunneling increases aeration and organic matter distribution; therefore horizons blend more rapidly rather than remaining distinct layers as through leaching alone.
