  Determining spatial variations of important soil features in a forest system could be, to great extent, helpful for characterizing soils to take management and preventive measures for reforestration. This study investigated spatial variability of soil organic matter (SOM), bulk density (BD), texture, pH and hydraulic conductivity (HC) in Cankiri Indagi Blackpine (Pinus nigra) plantation. Additionally, soil USLE erodibility factors were determined from five soil and soil-profile parameters to examine the sensibility of soils to water erosion processes, which was thought to be useful in managing and caring forest soils. These parameters were measured in a total of 52 samples obtained from depth of 0-10 cm from a 400 by 600 m area. Soils of the research site were classified after the soil genetic horizons were described and placed into orders, 2 sub-orders and 2 subgroups. According to the spatial analysis, ranges of semivariograms, which indicated the maximum distances for spatial correlations of the soil properties measured, were 330, 137, 120, 130, 1, 340 and 250 m for the soil organic matter, bulk density, clay, sand, pH, hydraulic conductivity and soil erodibility factor, respectively. Spatial dependence of the soil properties for short distances was determined as moderate in general and kriging maps for each soil property showed similarity for the organic matter, bulk density, clay and sand contents, which was indicator that to similar extent forest management practices could successfully be applied in the area to optimize resource use.
