| In order to verify the influence of class and use and occupation of land on water quality, it was performed the characterization and analyzes of land use and monitoring of seven springs inserted in a watershed located in the rural of Viçosa city - Minas Gerais (MG) state, in Brazil. Through soil analyzes, carried out in five different profiles, it was possible to identify three distinct pedological classes: Argisol, Cambisol and Latosol. Furthermore, the concentrations of Fe, Mn, Cu, Zn, Cr, Cd, Pb and Ni were identified in each of the horizons in the considered profiles. Water samples were collected and analyzed monthly, over eight months, twenty two parameters of water quality. Comparing the results of each survey, it was possible to identify a relation... |

| Characteristics of soils along footslope of limestone mountain were studied in farmer field used for growing sugarcane in Wangdong subdistrict, Muang district, Kanchanaburi province. There were eight locations selected, comprising lower footslope (ND-1), upper lower footslope (ND-2), lower middle footslope (ND-3), middle footslope (ND-4),upper middle footslope (ND-5), erosional lower upper footslope (ND-6), lower upper footslope (ND-7), and upper footslope (ND-8). This study aimed at investigating the relationship of soil characteristics and their position on footslope. Soil morphological, physical and chemical properties were examined and analyzed based on standard methods. All soils studied were classified as Aquic Haplustalf (ND-6), Inceptic Haplustalf... |

| The aim of this work was to evaluate the vegetative-productive balance of Vitis vinifera L., cvs. Merlot, Malbec and Cabernet Sauvignon on Aridisols with hardened layers in the Alto Valle of Rio Negro, Argentina. The study was carried out in 15.5 ha of vineyards during 2002-2003 on five soil groups characterized by: type, thickness and depth of the horizons, texture and resistance to penetration. In each sampling site three plants were evaluated. Production, leaf area, pruning material, trunk diameter, the Ravaz Index, the leaf area/yield ratio and the leaf area index were determined. A variance analysis and means comparison were made. The production level, the leaf area and the pruning material of the three cultivars were reduced (P < 0.05) when the... |
