Cattle treading accompanied by a high input of organic matter was previously found to favour methanogenesis in soils at a site used as winter pasture in outdoor cattle husbandry. In this current study, the phylogenetic microarray AnaeroChip revealed high methanogenic diversity in a cattle-impacted soil with predominance of Methanosarcina, and presence of Methanoculleus, Methanobacterium, Methanocalculus, Methanobrevibacter, Methanosaeta, Methanothermobacter, Methanogenium, Methanohalobium, Methanolobus. The bioturbation effects of an epigeic earthworm, Eisenia andrei, on the methanogenic microbial community in cattle-impacted soil were studied in a 6-month laboratory microcosm experiment. The microarray showed that the methanogenic community was changed by addition of earthworms to the soil.
