SOC and TN were therefore  investigated in 30 field sites comprising natural forests, planted  forests, shrub, and grasslands. SOC and TN stocks differed and correlated  significantly with land use age; the C stocks correlates significantly  with land use change compared the TN stocks. However, there was no  relation between the C and N stocks with elevation, implying that SOC and  TN are solely dependent on land use age. SOC sequestration potentials of  the sampled ecosystems were 345.86, 293.19, 266.45, and 251.23 t  ha\u22121\u00a0for the natural forests, planted forests, shrub, and  grasslands with total mean value of 289.18 t\u00b7ha\u22121\u00a0(1,060.42  t\u00b7ha\u22121\u00a0CO2\u2212eq). A significant SOC stock loss (17.96%, 29.80%, and  37.66%) occurred in converting natural forests to planted forests, shrub,  and grasslands, whereas gains (27.36%, 14.31%, and 5.71%) would occur in  reconverting grassland to natural forests, planted forests, and  shrublands. Therefore, the C that was lost during deforestation and  conversion of natural forests into other land use types could not match  the carbon gains thereafter. Our results suggest that land use change and  land use age have influenced soil C and N stocks. Moreover, natural  forests are better in ecological conservation and restoration of degraded  lands. This study provides baseline information for C and N management in  ecologically restored and degraded lands.", "keywords": ["2. Zero hunger", "land use change", "soil organic carbon", "13.
