1. Spatial variability of soil physical-hydric attributes under bovine trampling in agreste of Pernambuco State, Brazil
ABSTRACT. Soils under pastures suffer physical modifications, in greater or lesser intensity, via the action of animal trampling. Thus, the aim was to evaluate the spatial dependence of soil physical attributes under bovine trampling. The trial was performed at Roçadinho Farm, Agreste of Pernambuco, Brazil, in a 40 x 40 m paddock that was managed with conti

2. Atributos químicos e textura do solo em veredas conservadas e antropizadas no bioma Cerrado / Chemical attributes and texture of the soil in conserved and altered wetlands (veredas) in Cerrado biome
Este trabalho objetivou estudar os solos de áreas úmidas (veredas) situadas em ambientes conservados e antropizados (em áreas agrícolas e de pecuária), por meio da determinação de atributos químicos e textura do solo. O estudo foi realizado na região nuclear do bioma Cerrado, no estado de Goiás, em veredas situadas no município de Bela Vista de Go

3. Chemical attributes and texture of the soil in conserved and altered wetlands (veredas) in Cerrado biome / Atributos químicos e textura do solo em veredas conservadas e antropizadas no bioma Cerrado
The objective of this work was to study the soil of wetlands situated in conserved and altered environments (in agricultural and cattle areas), by determining the chemical attributes and texture of the soil. The study was carried through in the central region of Cerrado biome, in the state of Goiás, in wetlands situated in the City of Bela Vista de Goiás.

5. Critérios de relevância para classificação de cavernas no Brasil
What is the scientific basis used for the classification of caves in Brazil? Are the attributes identified today and the aspects evaluated sufficient to classify natural underground cavities? To answer these questions, 1,169 caves were selected as a sample of the universe of 6,522 natural underground cavities known and registered in Brazil. A questionnaire w

6. Variabilidade espacial de atributos fisico-hidricos do solo cultivado com feijão irrigado sumetido a diferentes sistemas de preparo / Soil physical-hydric attributes spatial variability doe diferent irrigated bean tillage systems
Since last decades irrigation practices are recognized as major water consumers, requiring specific agricultural producers education and awareness on water use and supply. Recent research reports indicate significant water economy, crop yielding as well as contribution to sustainable agricultural development, if direct seedling, when compared with convention

7. Variabilidade espacial da qualidade físico-hídrica do solo de um sistema em produção agroecológica. / Spatial variability of physical - hydric soil quality of an agroecological production system
The knowledge of physical hydric soil quality indicators is crucial during planning and management of agriculture activities. Many articles had been written to identify and to correlate the physical hydric soil quality and crop production. However, the most part of the results are not reliable for mapping spatial variability, mainly in large areas. The objec

8. Variabilidade espacial de atributos fÃsicos e hÃdricos do solo e da produtividade da cultura da soja em uma Ãrea comercial
Studies that involve the physical attributes and hydrics of the soil are important for the development of the maintainable agriculture. When the areas of cultivated lands are used with intense agricultural production, the soil presents alterations in their physical attributes and hydrics. The economical viability of the agricultural production depends of the

9. Hydric erosion and initial development of the Eucalyptus grandis in a Red-Yellow Argisol submitted to different methods of soil preparation in the Vale do Paraíba-SP region / Erosão hídrica e desenvolvimento inicial do Eucalyptus grandis em um Argissolo Vermelho-Amarelo submetido a diferentes métodos de preparo de solo no Vale do Paraíba - SP
In Brazil, and especially in the state of São Paulo in the Vale do Paraíba region, eucalypt plantation is expanding to high declivity areas occupied with degraded pastures due to the limited agricultural value of these topographies and its greatest forest aptitude. Such areas are naturally more susceptible to the hydric erosion, which reduces the fores
