Resumo: | The connected fragments of lowland and alluvial deciduous forests present topography with the large pedological and geomorphological variations. Thus, to understand the conditions in these environments, it was studied in details the conditions of soils and landforms present in small tributaries of a watershed in sedimentary geology, in the town of Pantano Grande, Rio Grande do Sul state. In order to assess these variables, it was established 200 plots of 100 m² divided into 40 sampling points with five plots each, the headwaters to the floodplain of the River Jacuí. In each sampling unit, it was collected surface soil samples for the analysis of fertility and granulometric composition. It was determined 16 soil classes until the fourth categorical level by the Brazilian System of Soil Classification and 12 geomorphological and soil compartments. In the ordination analysis, it showed differences between the sampling points of the plain and slopes. The variables altimetry, slope, soil texture, H + Al and CEC were the most important ones in the analysis of environment ordination. |

Assim, para entender as condições nesses ambientes, foram estudadas de forma detalhada as condições de solos e as formas de relevo presentes em pequenos tributários de uma microbacia de geologia sedimentar, no município de Pantano Grande, Rio Grande do Sul. Para levantar essas variáveis foram instaladas 200 parcelas de 100 m² distribuídas em 40 pontos amostrais com 5 parcelas cada, desde as cabeceiras de drenagem até a planície de inundação do rio Jacuí. Em cada unidade amostral foram coletadas amostras superficiais de solos para análise de fertilidade e composição granulométrica. Foram determinadas 16 classes de solos até o quarto nível categórico e 12 compartimentos geomorfológico e pedológico. A análise de ordenação demonstrou diferenças entre os pontos amostrais da planície e vertentes. As variáveis, altimetria, declive, textura do solo, H + Al e CTC foram as mais importantes na análise da ordenação do ambiente.Universidade Federal de Santa Maria2016-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2419810.5902/1980509824198Ciência Florestal; Vol. 26 No. 3 (2016); 747-761Ciência Florestal; v. 26 n. 3 (2016); 747-7611980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/24198/14152Copyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessScipioni, Marcelo CallegariGalvão, FranklinLonghi, Solon JonasPedron, Fabrício de Araújo2017-11-06T16:09:58Zoai:ojs.pkp.sfu.ca:article/24198Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-11-06T16:09:58Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
