1. Fertilidade do solo e estoques de carbono e nitrogênio sob sistemas agroflorestais no Cerrado Mineiro
Resumo Os sistemas agroflorestais são utilizados para diversificar a produção de alimentos, proporcionar aumento na biodiversidade da fauna e da flora e conservação do carbono e nutrientes no solo. Sendo assim, o objetivo deste estudo foi avaliar a fertilidade e os estoques de carbono (C) e nitrogênio (N) do solo após dez anos de implantação de sist

2. Structural and Floristic Variations in an Atlantic Subtropical Rainforest in Southern Brazil
ABSTRACT The Atlantic Subtropical Rainforest covers a huge area of Santa Catarina state, starting on the coast and going through the Serra Geral. Along its distribution, the vegetation changes according to altitude, geomorphology, and soil. In the attempt to evaluate vegetation variations related to different soil types in an Atlantic Forest remnant, 43 plo

3. As, Cu AND Zn CONCENTRATION IN SANITARY SEWAGE SLUDGE FERTILIZED SOIL AND IN CRAMBE AND CORN GRAINS
ABSTRACT This study aimed to evaluate the total contents of As, Cu and Zn in the profile of a Haplic Cambisol cultivated with crambe and corn and fertilized with sanitary sewage sludge and to compare them with those obtained in other forms of fertilization, as well as the content of metals in the grain of these crops. Two experiments were carried out in the

4. Weathering of Rhyolites and Soil Formation in an Atlantic Forest Fragment in Northeastern Brazil
ABSTRACT Weathering and pedogenesis have been studied for a wide range of rocks and climates around the world. However, the eruption of rhyolitic magmas is a rare geological event, which leads to few studies associated with the rhyolite-soil-landscape relationship. In this context, this study evaluated the influence of rhyolite weathering on the properties o

5. Caracterização de solos em uma topoclimossequência no maciço de Triunfo - Sertão de Pernambuco / Characterization of soils along a topoclimosequence in Triunfo mountain-semi-arid of Pernambuco state
High altitude forest in mountain of Northeast Brazil are islands of the Humid Atlantic forest in the middle of semi-arid region, with an atypical climatic condition, improved by the occurrence of orographic precipitions that can reach more than 1200mm per year. In Pernambuco state scientific studies in these humid sites were only related to botanic and biolo

6. Atributos do solo, ambientes e perdas de solo para Ãreas florestadas no sul e leste do Brasil / Soil properties, condition and soil losses for south and east Brazilian forest areas
Eucalyptus cultivation has increased in all Brazilian regions. In order to recommend good management practices it is necessary to understand differences in soil properties where eucalyptus is planted. In addition, aggregate stability analyses have proved to be a useful tool to measure soil effects caused by changes in management practices. Besides, the evalu

7. Produção de biogás, caracterização e aproveitamento agrícola do biofertilizante obtido na digestão da manipueira / Biogas production, characterization and agricultural use of the biofertilizer obtained in the cassava digestion
During the cassava roots processing, large quantities of waste are generated, among which stands out the manipueira, an effluent that has high polluting load, but on the other hand can be used as fertilizer and energy source. In this context, this study aimed to examine the anaerobic digestion of manipueira process, seeking to quantify the biogas produced it

8. Gênese, classificação e mapeamento de solos desenvolvidos de rochas pelíticas em áreas cultivadas com eucalipto em Minas Gerais / Genesis, classification and mapping of soils developed from pellitic rocks in areas cultivated with eucalyptus in Minas Gerais
Because the demand for arable areas has turned very intense in the last years, soils then considered as not appropriate to agricultural use are now being revalued and studied in order to use them for forest plantings, to example of Cambisols developed from pellitic rocks of Bambui Group. In reason of the expressiveness of these soils, usually associated Lato

9. Levantamento de solos em sub-bacias hidrogrÃficas como apoio para avaliaÃÃo do uso da terra e da potencialidade da recarga de aqÃÃferos. / Soil survey in hydrografic watersheds as support to evaluation of land use and aquiferous recharge potencial.
The knowledge of natural resources, mainly soil water, is fundamental for a better evaluation of land use in sustainable basis, indicating its potential and limitations for agricultural and non-agricultural exploration. This evaluation can be improved by the use of Land Agricultural Vocation Evaluation System, in which the differential impacts of limitations

10. Validação do modelo WEPP na predição de erosão hídrica para condição edafoclimática da região de Viçosa-MG / WEPP model validation in the prediction of water erosion for edaphic climatic conditions in the region of Viçosa-MG
The sensitivity analysis of the WEPP model demonstrated that for the Brazilian edaphic climatic conditions the most critical parameters from the soil are: the erodibility interril (Ki), the erodibility in rill (Kr), the critical shear strength (τc) and the effective hydraulic conductivity (Ke). Through is of fundamental importance the evaluation of the

11. Indicadores de qualidade estrutural na avaliaÃÃo da compactaÃÃo do solo em decorrÃncia da colheita mecanizada da cana-de-aÃÃcar. / Indicators of structural quality in the evaluation of soil compaction due to mechanized harvesting of sugarcane.
The mechanized harvesting of sugarcane in inadequate water contents in the soil has been responsible for soil compaction and reduction of yield in the later cycles of the crop. The identification of the impacts of mechanized harvesting of the sugarcane crop on soil structure, in different classes can become an important cropping strategy for minimization of

12. Composição, estrutura e aspectos ecológicos da mata ciliar do Rio Araguari no Triângulo Mineiro / Composition, structure and ecological aspects of forest riparian the Araguari River within Triângulo Mineiro region
The study aimed to characterize the tree-shrub community of a riparian forest, one of the last remnatns on the Araguari River, at Uberlândia, Triângulo Mineiro region, Minas Gerais State. The composition, horizontal and vertical structure were investigated by phytosociological survey of 110 plots of 10m x 10m (1,1ha). All trees with CAP ` 15 cm were regist
