Vertical electrical soundings using eletroresistivity method were carried out in the public waste landfill in Macapá - AP, having as a goal to investigate the geoelectrical and hidrogeologic characteristics of the ground. The results of geophysics interpretation allowed obtaining a model of five geoelectrical layers until the depth of 14,6 m. This model is correlated to a sedimentary sequence of clay-silt-sandy with laterite. The main flow of the water table, also determined, is concordant to the topographical gradient.

The objective of this study was to evaluate the behavior of morphological Eucalyptus platyphylla when subjected to five levels of soil salinity. The research project was conducted in a greenhouse at the experimental area of the Department of Agricultural Engineering of the FCA / UNESP, Botucatu-SP, utilizing plastic pots filled with soil containing NaCl concentrations, in sufficient quantities to raise the level of electrical conductivity. The experiment was conducted in randomized blocks in factorial scheme 5 x 4, 5 electrical conductivities (1.41, 2.50, 4.50, 6.45 and 8.33 dS m-1) and four repetitions. The results showed that soil salinity did not significantly affect the following parameters: height, green mass and dry matter of shoot, and root and leaf area of the plants.
