  abstract = {{D}isturbance induced by two contrasting irrigation regimes (groundwater versus urban wastewater) was evaluated on a sandy agricultural soil through chemical and microbial analyses. {C}ontrary to wastewater, groundwater displayed very high nitrate contents but small amounts of ammonium and organic matter. {D}espite these strong compositional shifts, soil organic carbon and nitrogen, nitrate and ammonium contents were not significantly different in both types of irrigated plot. {M}oreover, neither microbial biomass nor its activity, determined as fluorescein diacetate hydrolysis activity, was influenced by irrigation regimes. {B}acterial community structure, assessed by denaturing gradient gel electrophoresis ({DGGE}) of 16{S} ribosomal {DNA} fragments, was also weakly impacted as molecular fingerprints shared an overall similarity of 85%. {A}mmonia-oxidizing bacterial community ({AOB}) was monitored by {DGGE} of the functional molecular marker amo{A} gene (alpha subunit of the ammonia monooxygenase). {S}urprisingly, no amo{A} signals were obtained from plots irrigated with groundwater, whereas signal intensities were high in all plots under wastewater. {A}mong the last, compositional shifts of the {AOB} community were weak. {O}verall, impact of irrigation water quality on soil chemistry could not be evidenced, whereas effects were low on the total bacterial compartment but marked on the {AOB} community.},
