Forest ecosystems contribute significantly to store greenhouse gases. This paper aimed to investigate the spatial and vertical distribution of litter, roots, and soil carbon. We obtained biomass and carbon of compartments (litter, roots, and soil) in a vegetation from Cerrado biome, state of Minas Gerais, Brazil. The materials were collected in 7 0.5 m² sub-plots randomly allocated in the vegetation. Root and soil samples were taken from five soil layers across the 0-100 cm depth. Roots were classified into three diameter classes: fine (<5 mm), medium (5-10 mm), and coarse (>10 mm) roots. The carbon stock was mapped through geostatistical analysis. The results indicated averages of soil carbon stock of 208.5 Mg . ha -1 (94.6% of the total carbon), root carbon of 6.8 Mg . ha -1 (3.1%), and litter of 5 Mg . ha -1 (2.3%). The root carbon was majority stored in coarse roots (83%), followed by fine (10%), and medium roots (7%). The largest portion of fine roots concentrated in the 0-10 cm soil depth, whereas medium and coarse roots were majority in the 10-20 cm depth. The largest portion of soil (53%) and root (85%) carbon were stored in superficial soil layers (above 40 cm). As conclusion, the carbon spatial distribution follows a reasonable trend among the compartments. There is a vertical relation of which the deeper the soil layer, the lower the soil and root carbon stock. Excepting the shallowest layer, coarse roots held the largest portion of carbon across the evaluated soil layers. DISTRIBUIÇÃO ESPACIAL E VERTICAL DO CARBONO EM SERAPILHEIRA E SUBSOLO EM VEGETAÇÃO DO CERRADO BRASILEIRORESUMO: Ecossistemas florestais contribuem significativamente para estocar gases do efeito estufa. Objetivou-se investigar a distribuição espacial e vertical do carbono em serapilheira, raízes e solo. Foram obtidos biomassa e carbono de compartimentos (serapilheira, raiz e solo) em vegetação do bioma Cerrado, Minas Gerais, Brasil. O material foi coletado em 7 sub-parcelas de 0,5 m² aleatoriamente alocadas na vegetação. As amostras de raízes e solo foram tiradas de cinco camadas do solo na profundidade de 0-100 cm. Raízes foram classificadas em três classes: raízes finas (<5 mm), médias (5-10 mm) e grossas (>10 mm). Estoques de carbono foram mapeados usando análise geoestatística. Resultados indicaram médias do estoque de carbono no solo de 208,5 Mg . ha -1 (94,6% do carbono total), carbono nas raízes de 6,8 Mg . ha -1 (3,1%), e na serapilheira de 5 Mg . ha -1 (2,3%). Carbono de raízes foi majoritariamente estocado nas raízes grossas (83%), seguido das finas (10%) e médias (7%). A maior porção das raízes finas se concentrou na camada de 0-10 cm, enquanto que raízes médias e grossas majoritariamente entre 10-20 cm. A maior porção do carbono em solo (53%) e raízes (85%) estiveram estocados nas camadas superficiais do solo (acima de 40 cm). Como conclusão, a distribuição espacial do carbono segue razoável tendência entre os compartimentos. Há uma relação vertical de que quanto mais profunda a camada de solo, menor o estoque ...

Abstract:The vegetation of Gambella national park varies in terms of composition and structure due to the occurrence of rivers bisect the park. Data of the vegetation was collected by different techniques such as field observation, GIS and remote sensing, GPS and compass, and topographic map. The scientific name, local name and their uses was identify by indigenous knowledge of the community, experts knowledge and field guide line book for each tree species. Stratification was used of homogeneity/heterogeneity of the land use of the park and make easy ways for study. There were also 80 sample plots with 10m x10m rectangular plot size was taken to carry out counting and identifying the species using transect line in the study area. A total of 39 species were recorded and the most dominance species was Grewia mollis. The analysis indicated that the riverine forest was dense (more stems) than terrestrials forest. The highest stem grown in the Riverine forest was Grewia mollis A. Juss whereas terrestrial species was Bridelias cleroneura and also more tree species were available in terrestrial wood land forest than riverine forest. As move to the reverine forest, there was more vegetation, abundance, distribution and greenness. Land use land cover change indicated that terrestrial wood land forest is decreasing from time to time due to anthropogenic factors. Therefore, in order to keep the sustainability of the national park from deforestation there must be integration of stack holder organization, awareness creation of the community, participatory approach in the park is required.

“…The mean soil organic carbon stock stored in 100cm soil depth of all land uses are; for NF (170.11±14.59), SC (127.96±9.43),HG (107.62±12.55) and CF (97.56±6.85). This higher mean SOC stock can be due to the accumulation of higher organic matter in soil surface and fast decomposition of litter which results in maximum storage of carbon (Sheikh et al,2009). In the forest ecosystem due to the high plant coverage it contains higher litter accumulation in the soil surface.…”

Soil organic carbon is the carbon associated with soil organic matter that is made up of decomposed plant and animal materials. This study was conducted in Dallo Mena district to estimate the amount of soil carbon stock stored in shade grown coffee (SC) and homegarden agroforestry practices (HG), and adjacent natural forest (NF) and annual crop field (CF) and to show the potential of agroforestry practices in soil organic carbon storage capacity. The study site was selected based on spatial analogue approach.From each land uses nine plots were selected by using systematic sampling method following the transect line. Soil organic carbon stock (100cm depth) were the highest for the NF(170.11 ± 14.59 Mg ha Agroforestry and other land uses of Dallo Mena districts are providing various ecological as well as economical benefits for the community. It is used as income source, conserving different plant species diversity and at the same time storing large amounts of soil organic carbon. Therefore, there is significant difference among natural forest, shade grown coffee agroforestry practice, homegarden agroforestry practice and annual crop field in soil organic carbon storage capacity.
