The Relationships Between Some Ecological and Chemical Properties and Enzyme Activities in Soils of Soguksu National Park




Variations in acid and alkaline phosphatase and catalase enzyme activities in relation to altitude and pine forest vegatation in soils of Soguksu National Park were examined. Twenty-one samples were collected from surface soil (0-5 cm) at altitudes at 25 m intervals. Correlation coefficients were calculated between soil moisture, organic matter content, total-N, CEC, available P and K, altitude and the three enzyme activities. Significant positive correlations were recorded between acid phosphatase, alkaline phosphatase, catalase activity and the soil properties such as organic matter content, total-N, CEC, available P and K, soil moisture. A significant negative correlation was determined between altitude and enzyme activities. The results of the research indicated that enzyme activities were affected depending on altitude from which soil samples were taken.
