Natural ecosystems are influenced by improper and unplanned land uses, multi-faceted pressures caused by rapid population growth and indirectly physiographic factors. This study was carried out in order to investigate the relationship between land use and some physiographic characteristics and soil properties in Oltu Anzav vineyards basin of Erzurum province. In the study, the physiographic characteristics were determined by Geographic Information Systems (GIS) technology and the relations with some physical and chemical soil properties were examined by statistical analysis. The average elevation of the basin ranged from 730 to 2890 m and its area has extreme slope, steep slope and very steep slope groups according to the slope map. Basin lands belong to “Brown Forest Soil” class as great soil group. According to the results of analysis from 129 soil samples collected in the basin; Organic matter, sand, clay, silt, lime, EC and pH content were found as 0.05-6.04%,14.47-91.67%,3.33-55.11%, 3.90-50.22%, 0-63.13%, 0.04-1.98 mScm-1 and 5.71-8.84, respectively. In addition, phosphorus, exchangeable potassium, magnesium, sodium and calcium concentration varied between 2.03-241.30 ppm, 29.62-1261.50 ppm, 0.20-21.00 meq lt-1, 6.16-2019.00 ppm and 7.87-149.50 meq lt-1, respectively. In the analysis; It has also been determined that land use has a significant effect on OM content. Particularly the sand, clay and total lime content was affected out of the slope groups of the soil. Significant differences were determined between altitude groups and OM, sand, clay, silt, pH, total lime, phosphorus (P), K+, Na2+, Mg2+ values and between aspect groups and OM, total amount of lime and changeable Na+ concentration. Significant decreases in the rate of organic matter due to the increase in the elevation also indirectly affected the other dynamics of the soil. As a result, the physiographic characteristics play an important role on soil properties. This situation, in order to maintain sustainable forestry and agricultural activities, requires a detailed actual site survey to be carried out while planning forest, cropland and grassland management.
