- W3173620005 abstract "<strong class=journal-contentHeaderColor>Abstract.</strong> Research carried out on soil organic carbon stock (SOCS) in the Sudano-Sahelian region of Cameroon is very rare. The few existing studies are mostly available in reports and concern in most cases carbon stocks in plant biomass. In order to contribute to the documentation on soils in this part of the country, the present work was designed to evaluate the SOCS in the main soil types and the influence of environmental factors and soil properties on these stocks under the natural dry tropical area of the Sudano-Sahelian zone of Cameroon. The study was undertaken in four sites, including three natural forest reserves (Laf, Zamai, Kosohon) and one national park (Mozogo), located at different latitudes. Three replicates were collected at each site, giving rise to three sampling points chosen per site, from 0 to 75âcm depth, for the determination of SOCS. At each sampling point, soils were sampled using depth increments of 25âcm from the surface. The studied area is covered by Haplic Vertisols, Dystric Arenosols, Dystric Leptosols and Dystric Planosols. Total SOCS (T-SOCS) content, which refers to a depth of 75âcm, decreases with increasing latitude, with <span class=inline-formula>249±26.26</span>âMgâha<span class=inline-formula><sup>â1</sup></span> in Vertisols at Laf forest reserve most southerly located, <span class=inline-formula>199±8.00</span>âMgâha<span class=inline-formula><sup>â1</sup></span> in Arenosols at Zamai forest reserve, <span class=inline-formula>166±16.63</span>âMgâha<span class=inline-formula><sup>â1</sup></span> in Leptosols at Kosohon forest reserve and <span class=inline-formula>161±8.88</span>âMgâha<span class=inline-formula><sup>â1</sup></span> in Planosols at Mozogo national park most northerly located, regardless of the altitude. No significant correlation was noted between T-SOCS and the altitude. A good correlation was noted between precipitation which decreases with increasing latitude and T-SOCS, indicating the importance of climate in the distribution of T-SOCS in the study area, which directly influences the productivity of the vegetation. More than 60â% of the SOCS was stored below the first 25âcm from the soil surface, a peculiarity of SOCS in drylands. The SOCS in the Sudano-Sahelian area of Cameroon is mainly influenced by climate and vegetation." @default.
