Resumo: A toposequense of important soils of the middle plateau region of Rio Grande do Sul were studied with reference to their morphological, geomorphological, chemical and mineralogical properties in order to obtain information concerning their genesis, classification, and agricultural capability. The soils of the plateau are derived from basic igneous rocks as well as from deposits of sandy material, whereas the soils of the back slope and footslopes are derived from the underlying basalt, having also received material eroded from the deeply weathered soils of the undulating uplands. In spite of their steep gradients and stoniness, the soils of the slopes are preferred by farmers because they have clay minerals which have undergone fewer transformations and hence have greater fertility. Although the soils of the older surfaces present undulating relief, they are highly weathered and quite acid, with low reserves of plant nutrients.

Os solos dos planos elevados foram desenvolvidos a partir de rochas eruptivas básicas e com adição de material arenoso, enquanto que os solos das encostas e declividades inferiores foram originados do basalto subjacente, recebendo contribuição de material erodido dos solos profundamente intemperizados dos planos elevados. Os solos das encostas, apesar de seus fortes declives e pedregosidade, são preferidos pelos agricultores, por apresentarem argilo-minerais menos transformados e elevada fertilidade natural, enquanto que os solos das superfícies mais velhas apresentam relêvo ondulado, mas são fortemente intemperizados, com baixas reservas em elementos nutritivos para as plantas e são francamente ácidos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraKlamt, EgonBeatty, Marvin T.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17356Pesquisa Agropecuaria Brasileira; v.7, n.6, 1972: Série Agronomia; 99-109Pesquisa Agropecuária Brasileira; v.7, n.6, 1972: Série Agronomia; 99-1091678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17356/11612info:eu-repo/semantics/openAccess2014-04-15T18:40:30Zoai:ojs.seer.sct.embrapa.br:article/17356Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:40:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
