Conteúdo:  In thist study, land use and landscape quality were analyzed in the Queima-Pé river basin, Mato Grosso, Brazil. Land use and landscape quality were identified based on 3 m of spatial resolution images from GeoEye. For land use, manual segmentation and visual interpretation methods were used. Twelve map classes were identified and semi-perennial crops, temporary crops, pasture and native vegetation were the most significant ones. In terms of land use, the basin area contained 55.83% pasture, 26.06% crops, and 7.49% natural vegetation. Landscape analysis revealed that the study area contained 0.79% lower class, 87.80% medium-class, and 11.40% upper-class quality landscape. Through this analysis was determined predominance of the visual quality characterized as medium class, in the basin area.

Conteúdo:  A glasshouse experiment was condcted to determine how reduction conditions would affect plant nutrient availability and uptake in red-yellow latosol (Acrustox). Soil analysis showed that the most important change were a marked increase in extractable and in inhibition of nitrification. The grass andropogon (Andropongon gayanus Kunth var. bisquamulatus (Hoechst) Hack) and the legume stylo (Stylosanthes capitata (Vog) responded differently to reducing conditions. Andropogon showed low P, Ca, Mg Fe and Mn content in the shoots but an intense coating of oxidized iron was observed on the surface roots. Stylo plant, on the other hand, showed no iron deposition on the root surfaces a high iron content in the shoots. No decreased P, Ca or Mg content was observed in this case. Is was concluded tha in water saturated soil, reduction took place and plant performance was affected no only by restricted root development but by preventing P, Ca and Mg uptake in Andropogon and increasing Fe uptake stylo plants. It is suggested that restricted P, Ca and Mg uptake by Andropogen would be the result of iron deposition on root surfaces.
