13. Atributos físicos de solos e distribuição das fitofisionomias de cerrado na bacia hidrográfica do Rio Jardim, DF.
RESUMO: Avaliou-se a influência das características físico-hídricas de cada classe de solo da Bacia do Rio Jardim, DF e suas relações com as principais fitofisionomias correspondentes. Na caracterização dos perfis de solos, determinam-se a curva de retenção de água no solo e a capacidade de água disponível. As fitofisionomias identificadas foram

14. Relação solo-relevo-substrato geológico na planíce costeira de Bertioga (SP) / Soil-relief-geologic substract relationship on the coastal plain of Bertioga (SP)
Knowledge of the chronology, relief, geology and soils in sedimentary coastal environments is relevant for their interpretation, reconstitution and conservation. In Bertioga, São Paulo State Brazil, several sections of the Pleistocene and Holocene morphostratigraphic costal plain units are preserved in the landscape. This thesis seeks the perception of the

15. Characterization of organic matter as support to the study of the formation of surface horizon in soils under minimum cultivation of eucalyptus. / CaracterizaÃÃo da matÃria orgÃnica como subsÃdio ao estudo da formaÃÃo de horizonte superficial em solos sob cultivo mÃnimo de eucalipto.
In Brazil, a substantial part of the forest plantations has been undertaken in areas in which the soil presents some degree of physical, chemical or biological degradation. The protection provided by tree canopy of forest plantations and soil cover, as a function of the deposition of litter, is one of the most important processes in the recovery of degraded

16. 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

17. Conhecimentos na análise de ambientes: a pedologia e o saber local em comunidade quilombola do norte de Minas Gerais / Knowledge in the environment analysis: the pedology and local knowledge in the quilombola community on northern Minas Gerais
Theren increasing incorporation and appropriation of the epistemologies towards the sustainability, valorization of the man-environment relationships and the perception of the need for maintaining the complexity of the productive systems in response to the environmental degradation process, aggravated by practices of the reductionist paradigms. Local knowled

18. 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

19. Environmental representativeness and forest fragmentation in areas dominated by eucalyptus plantations: a proposal for the spatial arrangement of forest fragments / Representatividade ambiental e fragmentação florestal em áreas dominadas por plantios homogêneos: uma proposta para o arranjo espacial de fragmentos florestais
This work presents a landscape study in areas dominated by eucalyptus plantations and native forest. The objectives were to evaluate the spatial configuration and the physiographic and pedologic heterogeneity of native forest fragments, aiming to establish scenarios of arrangement of these fragments that maximize the environmental representativeness of the l

20. Caracterização e classificação de solos da Ilha de Fernando de Noronha (PE)
In the main island of Fernando de Noronha Archipelago, the dry tropical climate with oceanic influence and the recent parent material of volcanic origin, are responsible for the small weathering of soils with high scientific importance for the development of the Brazilian System of Soil Classification (SiBCS). Seven representative soil profiles, involving tw

21. Bacterial Diversity in Agricultural Soils during Litter Decomposition
Denaturing gradient gel electrophoresis (DGGE) of amplified fragments of genes coding for 16S rRNA was used to study the development of bacterial communities during decomposition of crop residues in agricultural soils. Ten strains were tested, and eight of these strains produced a single band. Furthermore, a mixture of strains yielded distinguishable bands.
