Micro-scale dry bulk density variation around earthworm (Lumbricus terrestris L.) burrows based on X-ray computed tomography by Rogasik, Helmut, Schrader, Stefan, Onasch, Ingrid, Kiesel, Joachim, Gerke, Horst H.

“…The burrowing activity of earthworms leads to soil structural changes by compaction of surrounded soil matrix, which represents the so-called drilosphere. This…”
