Summary We investigated the effect of untreated and biologically treated olive mill wastewater (OMW) spreading on the soil characteristics and the microbial communities. The water holding capacity‚ the salinity and the content of total organic carbon‚ humus‚ total nitrogen‚ phosphate and potassium increased when the spread amounts of the treated or untreated OMW increased. The OMW treated soil exhibited significantly higher respiration compared to the control soil. However‚ the C-CO2/Ctot ratio decreased
