Soil salinity and arbuscular mycorrhizal fungi (AMF) might influence the soil physical properties. Three experiments were performed to determine the effects of soil salinity and AMF species on soil structure, soil water repellency (R) and plant available water. Six AMF treatments including four exotic species ( Rhizophagus irregularis , Funneliformis mosseae and Claroideoglomus claroideum , a mix of three species), one mix native AMF species and an AMF–free soil with four salinity levels (1, 5, 10 and 15 dS m -1 ) were used. The results showed that the soil stability ratio increased in the presence of native AMF treatment and the greatest soil stability was observed at 10 dS m -1 . The R value increased with salinity increment. The mix of three exotic and native AMF enhanced the R significantly compared to AMF–free soil in all salinity levels. The lowest LLWR 100 and LLWR 330 were found at 1 dS m -1 and then increased by salinity until 10 dS m -1 . The greatest IWC was found at 1 dS m -1 and decreased by salinity. In addition, the AMF increased the LLWR 100 , LLWR 330 and IWC. It is concluded that the physical quality of soil in this experiment was determined by the salinity level and different AMF species.
