Some soil properties could be changed by parent material, topography, climate vegetation cover and time. Mineral contents in soil, considered, in relation with vegetation cover, also soil minerals are in relation with parent material, relief, time differences and local differences of vegetation cover. In this study, the soil properties of Van’s city center and its vicinity areas are found out that they were changed by product pattern and parent material. 1/25000 scale topography, belongs to that study area, land use, geology and geomorphplogy maps were used in this research. By using these maps, nine soil samples from different units where field crops are grown and different geological and geomorphological units were collected from 0-30 cm depth. Soil’s pH, EC, soil texture CaCO3, organic matter, total nitrojen and available phosphorus analysed. According to the results obtained from research, the pH values of soil were moderate alkaline and alkaline; the CaCO3 contents varied medium and high due to the effects of main material. In textural contents of soils, the effects of parent material and vegetation cover were observed and they were found in medium and heavy textured groups. Soil’s EC values were in non-salty soil class. The contents of organic matter varied with vegetation cover and they were found out sufficent especially in areas where forage plants were grown and pastured. Similarly, determined that the soil’s nitrojen contents, essential plant nutrient element, are low and medium. The phosphorus contenst of soils varied with fertilization and were generally low. The soil properties of Van’s city center and its vicinity areas were changed and varied with the vegetation cover and the parent material.
