Resumo: | Establishing Comperj (petrochemical complex Petrobras and partner companies at Itaboraí city, Rio de Janeiro State, Brazil) involves a great impact on natural environment, while it is an opportunity for actions of environmental compensation. The objectives of this study were to characterize soil chemistry and mineralogy of Comperjarea, based on landscape, particle size distribution and soil morphology, also considering different parent materials, landscape positions (shoulder, backslope and footslope at the hillslope and toeslope at floodplain) and vegetation cover groups. Different landscape positions, comparing toeslope and average hillslope, have differential behavior on several chemical attributes, besides those associated with landscape position itself (topography and water regime). Along the hillslope, differences on surface soil samples also occurred, considering studied attributes, among different parent materials and vegetation covergroups. Sites of both vegetation cover groups (forest and pasture) along the hillslope showed differences on many chemical attributes, except for organic C average valuesthat were not differentiated among them. Soil mineralogy on all samples was extremely kaolinitic and there were small differences among parent material groups. Soilconsistencies observed were very to extremely hard on both soil parent material groups, Proterozoic and Tertiary. |

O presente trabalho procurou caracterizar a química e a mineralogia dos solos da área do Comperj, considerando a granulometria e a morfologia dos solos, como também os diferentes materiais de origem, as posições de paisagem (terços superior, médio e inferior de encosta e terraços da planície) e as diferentes coberturas vegetais atuais. As paisagens de planície e encosta apresentam diferenças de comportamento de vários atributos químicos do solo, além daquelas associadas à própria paisagem (relevo e regime hídrico). Nas encostas também ocorrem diferenças de comportamento entre as amostras de solo, em função da origem litotípica e da fitofisionomia atual. Os sítios de floresta e pastagem das encostas apresentam comportamento diferenciado para vários atributos químicos, ressaltando-se, entretanto, que os valores médios de C orgânico não diferiram entre os dois grupos. A mineralogia de todos os solos é extremamente caulinítica, observando-se poucas diferenças entre os grupos dos litotipos. A consistência muito a extremamente dura no topo do horizonte B foi descrita para perfis de solo de encosta dos dois grupos de material de origem (Proterozóico e Terciário).Embrapa Florestas2014-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/56710.4336/2014.pfb.34.77.567Pesquisa Florestal Brasileira; v. 34 n. 77 (2014): jan./mar.; 1-11Pesquisa Florestal Brasileira; Vol. 34 No. 77 (2014): jan./mar.; 1-111983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/567/352Gomes, João Bosco VasconcellosCurcio, Gustavo RibasDedecek, Renato AntonioRamos, Michele Ribeiroinfo:eu-repo/semantics/openAccess2017-04-28T12:47:45Zoai:pfb.cnpf.embrapa.br/pfb:article/567Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:47:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
