Vertical distribution of soil properties and soil organic carbon in community managed forest of Siwalik Hill, Nepal

Abstract. Lamichhane U, Ghimire P. 2022. Vertical distribution of soil properties and organic carbon in community managed forest Siwalik Hill, Nepal. Asian J For 6: 91-96. Nepal's Community Forestry (CF) approach is globally recognized as an innovative successful to resource management. Shorea robusta Gaertn. the dominant tree species which covers 19.28% total stem volume country's area. Soil represents a significant terrestrial Carbon (C) pool can play role mitigating global warming. Therefore, analyzing physicochemical Organic (SOC) stock essential because they are key parameters for evaluating land use management systems. The present study was conducted Durga Mai Forest (DMCF) Makawanpur District, Nepal, assess vertical SOC stock. samples within 1 m profile five depth layers (0-20 cm, 21-40 41-60 61-80cm, 81-100 cm) were collected analyzed Bulk Density (BD), texture, pH, content, Total Nitrogen (TN), Available Phosphorous (AP), Potassium (AK) Sandy loam textural class reported throughout Average BD, TN, AP, AK S. forest's found be 1.16 ±0.07 gmcm-3, 5.78 ±0.62, 0.14 ±0.04 %, 5.94 ±1.04 kgha-1, 104.20 ±19.66 respectively. results estimated 107.57 ±3.06 tha-1 profile, with 0.93 ±0.21% average content. Further, decreased increase depths. Similarly, depths significantly affected like AK.
