Soil organic carbon and soil organic carbon pool in the managed and unmanaged beech-hornbeam stand

In the present study the impact of silviculture activities on soil organic carbon (SOC) and soil organic carbon pool (SOCP) in the mixed beech-carpinus forest located in district one of Shastkolate forest, Golestan province, was investigated.
In the first month of growth season in 2014, from 4 one-hectare treatments, 80 soil samples were randomly collected (up to depth of 20 cm) for organic carbon and coarse fragments estimation and 80 soil sample cylinders were collected for bulk density measurement. Treatments were 3 managed forests (selection system) in time periods of 1, 7 and 10 after the last disturbance and 1 unmanaged forest (control). Amounts of SOC and SOCP in different treatments were compared by one-way variance analysis.
Findings: Result showed that the amounts of SOC and SOCP in 4 treatments were different significantly (p
