- Abstract
Background: Soil samples were taken from a depth of 0-10 cm under the Quercus cerris and Fraxinus excelsior at an altitude of 1300-1500 m from the Kullin site at Gulnar-Mersin and were compared for their pH, CaCO3, nitrogen (N) %, and carbon (C) % contents. Balanced soils in natural forest ecosystems are known to be very rich in carbon content which increases with latitude and altitude and that the C/N ratio varies greatly between the soils of different plant species. We determined the values of the C/N rates in Q. cerris and F. excelsior soils of the Gulnar Gezende forest for the first time at this altitude. Material and Methods: A pH meter and Scheibler calcimeter were used to determine the soil pH and lime contents respectively. Percentage C was determined using the Anne method and the N% with the Kjeldahl method. Results: There was no difference in the pH values and nitrogen percentage contents between the two soils. Q. cerris soil was found to have medium levels of CaCO3, while the level of CaCO3 in F. excelsior soils was low. The C/N rates and carbon contents were higher in Q. cerris soil than F. excelsior soil (P<0.05). Conclusions: The higher carbon content of Q. cerris soil can be explained by higher amounts of organic matter compared with F. excelsior, which might depend on factors such as microclimate and their specific characteristics.
