Abstract: Forests of Carya cathayensis (Chinese hickory), a unique tree species with seeds that produce high-grade oil. Intensive management including heavy application of chemical fertilizer and long-term application of herbicides has resulted in serious soil organic carbon (SOC) decrea. To evaluate what kind of composition of SOC decrea, soil samples collected from intensively-managed forests (IMF) of 5, 10, 15, and 20 years were compared to samples of IMF forests newly converted (year 0) from an evergreen and deciduous broadleaf forest (EDBF). The results indicated that SOC, light fraction organic carbon (LFOC), and high fraction organic carbon (HFOC) decreased after converting an EDBE to an IMF. Compared to the EDBF, in the Chinese hickory forest with 20 years intensive management, there was a decrease in SOC (38.6%), LFOC (68.2%), and HFOC (26.0%). After 5 years of intensive management, LFOC/SOC decreased from 23.0% to 17.0%; whereas HFOC/SOC increased from 70.0% to 83.0%. The results demonstrate that LFOC is the main composition of SOC decreased after converting an EDBE to an IMF. [Ch, 3 fig. 2 tab. 26 ref.]
