One of the most important features of the arid and semiarid land soils is that they generally have high lime content. Although the effects of lime on the soil properties are generally known. However, there are not enough studies about the effects of high lime content in this region. For this reason, this study was aimed to make a simulation with the inherent lime content of the soils in this area and investigate its effect on some soil physical and chemical properties in the two contrasting texture soils. Clay and sandy loam soils which were obtained from this area, were mixed with micronized lime at the rate of 0, 5, 10, and, 20% (w/w), and then incubated at field capacity under laboratory conditions for one month. After the incubation period, the effects of increasing doses of lime applications on soil bulk density (HA), particle density (TY), mean weight diameter (AOÇ), aggregate stability (AS), liquid limit, plastic limit, plasticity index, pH, electrical conductivity (EC) organic carbon content (OC), mineralization of organic carbon (KM), total nitrogen (TN) and C/N ratio were determined. Accordingly, when 20% lime applications in clayey and sandy loam soils compared to controls (20% lime application measurement / control measurement) pH rations increased at the same level (1.01), while CaCO3, C / N and HA rations increased at the ratio of 2.09-2.59, 1.17-1.20 and 1.06-1.02; TY, AOÇ, EC and liquid limit decreased at the ratio of 1.03-1.07, 1.41-1.36, 0.84-0.96 and 0.86-0.94, respectively. The effects of lime applications on other soil properties varied depending on the soil texture. Except for the lime content, the highest variability in soil properties compared to the control were in TN and AOÇ values in clay soil and in AS and AOÇ values in sandy loam soil.
