Resumo: | Currently understand the factors that influence the emissions of CO2 in the Amazonian environment has been discussed more intensively, because the rapid increase in climatic variations (temperature and precipitation) which influence the exchanges between terrestrial ecosystems and the atmosphere. Given the above, the objective of this study was to evaluate the spatial distribution of CO2 emissions and soil properties under native pasture in Humaitá region, Amazonas. A sampling grid of 70 m x 70 m with 64 points regularly spaced at a distance of 10 m and georeferenced was delimited. Soil samples were collected at each grid point in layers of 0.00 to 0.05 m and 0.05-0.10 m for determination of soil physical properties and organic carbon, 128 soil samples. At the crossing points in the morning they were evaluated CO2, temperature and soil moisture, using the LI-6400 system. CO2 emissions in native pasture area in the present study conditions are complex nature of phenomena, it is not possible to identify a single soil attribute or the environment to explain the variation in space, thus indicating that a difficulty in establishing relationships between attributes soil and CO2 emission is due to the complexity of the phenomenon. |

Diante do exposto, objetivou-se com este trabalho avaliar a distribuição espacial da emissão de CO2 e atributos do solo sob campo nativo na região de Humaitá, Amazonas. Foi delimitada uma malha de 70 m x 70 m com 64 pontos amostrais espaçados regularmente pela distância de 10 m. Esses pontos foram georreferenciados e, em seguida, foram realizadas as coletas de solo em cada ponto da malha nas camadas de 0,00-0,05 m e 0,05-0,10 m para determinação dos atributos do solo, totalizando 128 amostras de solo. Foram avaliados o fluxo de CO2, fatores ambientais (temperatura e umidade do solo), atributos físicos (macroporosidade, microporosidade, porosidade total e densidade do solo), carbono orgânico total e estoque de carbono. As emissões de CO2 na área de campo nativo nas condições do presente estudo são fenômenos de natureza complexa, não sendo possível identificar um único atributo do solo ou do ambiente que explique sua variação no espaço, indicando assim que a dificuldade encontrada ao estabelecer relações entre os atributos do solo e emissão de CO2 ocorre devido à complexidade do fenômeno.Universidade Federal de Uberlândia2016-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/31502Sociedade & Natureza; Vol. 28 No. 2 (2016)Sociedade & Natureza; v. 28 n. 2 (2016)1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/31502/pdfCopyright (c) 2016 Revista Sociedade & Naturezainfo:eu-repo/semantics/openAccessMantovanelli, Bruno CamposCampos, Milton Cesar CostaAlho, Leandro CoutinhoSilva, Paula CarolineSilva, Diogo André PinheiroCunha, Jose MauricioSilva, Douglas Marcelo PinheiroSoares, Marcelo Dayron Rodrigues2021-04-30T14:00:57Zoai:ojs.www.seer.ufu.br:article/31502Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-04-30T14:00:57Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
