Resumo: | Soil characterization by photopedology studies are important tools in soil survey. Aerial photographs were used in a study of drainage network and its quantitative and descriptive characteristics were obtained in four areas located in Paraná State, Brazil, in soils developed from basic and acid rocks. In the aerial photo 1:25,000 scale, circular sampling with 10 km2 were selected, both developed from acid rocks. The parameters of drainage pattern permit to separate the soils developed from basic rocks and soils developed from acid rocks. The descriptive analysis was useful to differentiate the soil units, but was not so sensible as drainage density. The drainage density in circular sampling was the best index for characterization of soils units. Soils developed from acid rocks have different drainage pattern when compared with similar soils developed from basic rocks. The drainage density can be considered a weathering index for the same rock, for basic or acid rocks. |

Foram estudados, em quatro regiões do Estado do Paraná, solos desenvolvidos de rochas eruptivas básicas e ácidas, utilizando-se fotografias aéreas de escala 1:25.000, nas quais foram locadas amostras circulares de 10 km2. Foram caracterizados e estudados os padrões descritivos e quantitativos da rede de drenagem dos solos. Também observaram-se as relações existentes entre o grau de evolução desses solos e os índices de drenagem. A análise descritiva mostra-se útil na diferenciação dos solos, entretanto, foi um parâmetro menos sensível que a densidade de drenagem, que permitiu discriminar os solos desenvolvidos de rochas básicas bem como os de rochas ácidas. Os solos originados de rocha ácida possuem uma rede de drenagem diferente de seus pares originados de rocha básica. O índice densidade de drenagem pode expressar o grau de evolução dos solos em um mesmo substrato rochoso, no caso rochas básicas ou rochas ácidas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlexandre Melo Demattê, JoséAntônio Demétrio, Valdemar1998-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4819Pesquisa Agropecuaria Brasileira; v.33, n.1, jan. 1998; 87-95Pesquisa Agropecuária Brasileira; v.33, n.1, jan. 1998; 87-951678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4819/6936info:eu-repo/semantics/openAccess2014-11-10T18:46:35Zoai:ojs.seer.sct.embrapa.br:article/4819Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-10T18:46:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
