The objective of this study was to investigate the population of the arbuscular mycorrhizal fungi (AMF) and the effect of soil properties on AMF population in the semi-arid ecosystem of the Lake Tuz in Turkey. The analysis values of physical, chemical of soils, infection status of AMF in plants and spore densities of AMF in soil were evaluated, statistically. The AMF spore colonization percentage and spore density ranged from 0.00 to 67%, 0 to 1188 pores per 10 g soil -1, (with an average of 480.18 pores per 10 g soil -1) respectively. A very weak and negative correlation was determined between soil properties in research areas and the spore densities of AMF. But, only the percentages of CaCO3 (0.64) had a significant positive correlation (P<0.05) with spore number of the AMF. The Mg, Cu and Zn content of soil were significant positive correlation with infection rate (0.65, 0.73 and 0.69 respectively) and negative but non significant correlation between infection rates with EC, P, Na contents of soil. The spore isolated from saline soils when examined in terms of shapes and colors, it was determined that they had varied colors changing from transparent to black. In conclusion, there were a suitable population of AMF and infection of plant roots in saline soils of Turkey. © 2011 Academic Journals.
