The functional role of earthworm mucus during aggregation

Tom Guhra,
Arnold Wonneberger,
Katharina Stolze
et al.

Abstract: BackgroundSoil organisms influence pedogenesis on a molecular level through the production of biopolymers which interact with soil minerals depending on their molecular properties. Specifically, biopolymers impact structure formation by inhibiting aggregation as a separation agent or promoting aggregation as a bridging agent. Mucus is a biopolymer excreted by earthworms that consists mainly of proteins, polysaccharides, and, to a lesser extent, lipids. However, despite earthworms’ fundamental contribution to s… Show more

“…Increasing soil organic matter can increase the root length density value. Soil organic matter contributes to enhancing the physical characteristics of soil, including soil aggregation, pore size distribution (which promotes increased soil organism activity, particularly in the vicinity of root zones, thereby influencing the creation of new soil pores), bulk density, and porosity (Guhra et al, 2023). Lrv and Drv values in bending and control management showed decreasing values in each soil depth.…”
