| Abstract Pedological surveys and physiographic characterization of a watershed are fundamental procedures for planning the soil use. Thus, the aim of this study was to characterize and map the soil classes of the Lajeado Pessegueiro watershed, located in Guarujá do Sul, Santa Catarina, Brazil. The types of land use and occupation, slope classes and physiography of the study area were delineated and described. Data were collected from 19 complete soil profiles and 9 extra samples. Physiographic analysis was performed using prior information on the photopedology of the terrain geomorphological characteristics, climatic conditions, vegetation, land use and geological conditions. The watershed has a predominant undulating relief (406.51 ha). The predominant... |

| This study compares the chemical composition of the solution and exchange complex of soil in a 3-year-old irrigated vineyard (Vitis vinifera L., Red Globe cultivar) with that of adjacent clearing in the native hyperxerophyllic 'caatinga' vegetation. The soils are classified as Plinthic Eutrophic Red-Yellow Argisol; according to Soil Taxonomy they are isohyperthermic Plinthustalfs. Detailed physiographic characterization revealed an impermeable gravel and cobble covering the crystalline rocks; the relief of this layer was more undulating than the level surface. Significant higher concentrations of extractable Na, K, Mg and Ca were observed within the vineyard. Lower soil acidity, higher Ca/Mg ratios, as well as lower sodium adsorption and Na/K ratios... |

| Objetiva-se delimitar e quantificar a planicie do Pantanal no Brasil, na escala de 1:250.000, sua sub-regioes e a participacao estadual e municipal nessa regiao. Os criterios adotados na delimitacao foram aspectos relacionados a inundacao, relevo, solo e vegetacao. Os materiais utilizados foram os estudos anteriores relacionados a delimitacao fisiografica do Pantanal, Sistema Global de Posicionamento (GPS), mapas municipais estatisticos, cartas topograficas e imagens coloridas do satelite Landsat 5 TM, ambos na escala de 1:250.000, apoiados em trabalhos de campo. A extracao das informacoes foi feita a partir de metodos de interpretacao visual das imagens. Os criterios adotados mostraram-se consistentes na delimitacao, e a inundacao e o relevo foram os de... |
