It is widely accepted that earthworm activities participate greatly to soil processes by the
bioturbation of large volumes of soil. In particular, their disturbances affect primarily the soil
bacteria communities by their gut transit. However, while earthworm cast biostructures deviate
from surrounding soil in term of morphology and availability of organic matter compound, little is
know about the persistence of a functional discrimination of microbial biota within soil
biostructures. In this work, we have considered that the bacterial communities could vary
according to the aged of cast deposition, to the location of cast and also to OM nature initially
ingested by earthworm.
Based on the classification of soil structures observable on soil profile (Piron et al, 2008), we
sampled soil cores corresponding to physicogenic soil structures (e.g. S- Surrounding soil and
Ag- granular plough structure) and to biogenic structures (e.g. B3g and B3i that represent
respectively some recent granular and welded packing of cast deposition). So, soil material
was collected at different depths and under contrasted soil management in the experimental
plot of Kerguéhennec (France) that compared impact of different fertilisations (mineral fertilisation
vs poultry manure) combined to different tillage practices.
On each soil cores, Ctot and Ntot were measured. Moreover, we considered soil bacterial
community by the fingerprinting of 16S rRNA gene fragment assessed by terminal restriction
fragment length polymorphism (T-RFLP).
First results demonstrated that the manure input enhanced the Ctot rate in the first centimetres
for both physicogenic and biogenic soil structures. However, differences clearly appeared with
the depth: biogenic structures significantly concentrated Ctot below 20 cm.
The variability of bacterial communities will be discussed in regard to this spatial variability of
Ctot and Ntot content, and the different fertilisation treatments. MenosIt is widely accepted that earthworm activities participate greatly to soil processes by the
