OC and TN levels were highest under long-term leucaena\uffe2\uff80\uff93grass pasture (P\uffe2\uff80\uff89&lt;\uffe2\uff80\uff890.05). For leucaena\uffe2\uff80\uff93grass pastures that had been established for 20, 31, and 38 years, OC accumulated at rates that exceeded those of the adjacent native grass pasture by 267, 140, and 79\uffe2\uff80\uff89kg/ha.year, respectively, while TN accumulated at rates that exceeded those of the native grass pastures by 16.7, 10.8, and 14.0\uffe2\uff80\uff89kg/ha.year, respectively. At a site where 14-year-old leucaena\uffe2\uff80\uff93grass pasture was adjacent to continuously cropped land, there were benefits in OC accumulation of 762\uffe2\uff80\uff89kg/ha.year and in TN accumulation of 61.9\uffe2\uff80\uff89kg/ha.year associated with the establishment of leucaena\uffe2\uff80\uff93grass pastures. Similar C\uffe2\uff80\uff89:\uffe2\uff80\uff89N ratios (range 12.7\uffe2\uff80\uff9314.5) of soil OC in leucaena and grass-only pastures indicated that plant-available N limited soil OC accumulation in pure grass swards. Higher OC accumulation occurred near leucaena hedgerows than in the middle of the inter-row in most leucaena\uffe2\uff80\uff93grass pastures. Rates of C sequestration were compared with simple models of greenhouse gas (GHG) emissions from the grazed pastures. The amount of carbon dioxide equivalent (CO2-e) accumulated in additional topsoil OC of leucaena\uffe2\uff80\uff93grass pastures \uffe2\uff89\uffa420 years old offset estimates of the amount of CO2-e emitted in methane and nitrous oxide from beef cattle grazing these pastures, thus giving positive GHG balances. Less productive, aging leucaena pastures &gt;20 years old had negative GHG balances; lower additional topsoil OC accumulation rates compared with native grass pastures failed to offset animal emissions. </p>", "keywords": ["Carbon sequestration", "2.

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.
