We investigated the relationship between vegetation type and soil carbon dynamics in even-aged alder (Alnus hirsuta) and Korean pine (Pinus koraiensis) plantations in central Korea. Both forests were located on the same soil parent material and occupied similar topographic positions. Soil CO2 efflux in the two plantations was determined using a dynamic chamber method accompanied by measurements of soil moisture content and temperature. Mean soil temperature was similar in the two plantations, but mean soil water content was significantly higher in the alder plantation than in the pine plantation. In both plantations, seasonal patterns in soil CO2 efflux exhibited pronounced variation that corresponded to soil temperature. Soil water content did not affect the seasonal variation in soil CO2 efflux. However,in summer, when soil temperature was above 17oC, soil CO2 efflux increased linearly with soil water content in the alder plantation. Estimated Q10 was 3.3 for the alder plantation and 2.7 for the pine plantation. Mean soil respiration during the measurement period in the alder plantation was 0.43 g CO2 m−2 h−1, which was 1.3 times higher than in the pine plantation (0.33 g CO2 m−2 h−1). Higher soil CO2 efflux in the alder plantation might be related to nitrogen availability, particularly the concentration of NO3 −, which was measured using the ion-exchange resin bag method.
