The objectives of this study were to determine the effects of clearcutting on the organic carbon stock (SOC) and selected hydro-physical soil properties of the topsoil and the correlations between these properties with soil temperature, soil moisture, and herbaceous vegetation. The research was conducted in the oak-hornbeam forest. The topsoil was sampled 3 times a year in both control and treatment plots after clear-cut timber removal from the treatment plots. The clearcutting decreased SOC, organic matter (OM), and permeability (HC) values of the soil by 62.87%, 72.35%, and 89.12%, respectively, while increased particle density (PD), pH, bulk density (BD), and dispersion ratio (DR) values by 10.91%, 15.15%, 31.30%, and 104.43%, respectively. Results showed that soil temperature was the main factor affecting SOC and has negative correlations with SOC, OM, EC, field capacity (FC), permanent wilting point (PWP), available water capacity (AWC), HC, saturation capacity (SC), and total porosity (TP) and positive correlations with pH, BD, PD, and DR properties of the soil (p<0.05). Moreover, it was determined that soil moisture had a positive correlation with AWC and DR and a negative correlation with HC and TP. Also, vegetation cover had a positive correlation with pH and a negative correlation with SC.
