We examined soil CO"2 efflux and potential controlling factors in managed mixed pine forests in southwestern Georgia. Soil CO"2 efflux was monitored periodically in two stands that differed in soil texture in 2001 and 2002, and in six additional stands in 2003. We also monitored controlling factors: soil temperature, moisture, organic layer mass, and A layer depth. Soil moisture and CO"2 efflux varied with soil texture differences among the stands. As expected, soil temperature had a strong influence on soil CO"2 efflux. Soil moisture, organic layer mass, and A layer depth also were correlated with soil CO"2 efflux during periods of water stress, but these relationships differed with soil texture. Forest management activities can alter components of soil CO"2 efflux, including soil carbon pools, temperature, and moisture; understanding the underlying variation of these components and resultant CO"2 efflux over soil types can help guide management toward desired forest carbon balance trends in southeastern mixed pine forests. |
