In this study, the dynamism of forest areas was tried to be determined by determining the ecological differences between the areas where Fagus orientalis Lipsky. (Eastern beech, Fagaceae), a very important species for forestry in Turkey, and the soils of agricultural fields. lime %, total salt %, pH, texture, field capacity %, C%, N%, C/N ratios, 30-day carbon mineralization of the lands of Eastern beech forests and agricultural fields, which are naturally formed in Sivas province Koyulhisar district, under controlled conditions (28°C, 80 humidity %) was determined by the respiration method, and two areas in two different ecosystems were compared. When the carbon mineralizations of eastern beech soils were examined seasonally, it was determined as 19.54>18.23>17.87>17.18 mg C(CO2)/100g DS/30 day in spring>autumn>summer>winter seasons, while it was determined as 14.46>13.87>13.68>13.65 mg C(CO2)/100g DS/30 day in autumn>summer>spring>winter seasons in agricultural soils, respectively. Significant relationships were found between the C%, N%, 30-day carbon mineralization cumulative values and % carbon mineralization rates between both areas.
