5. First Assessment of Carbon Stock in the Belowground Biomass of Brazilian Mangroves
ABSTRACT Studies on belowground roots biomass have increasingly reported the importance of the contribution of this compartment in carbon stock maintenance in mangrove forests. To date, there are no estimates of this contribution in Brazilian mangrove forests, although the country has the second largest area of mangroves worldwide. For this study, trenches d

6. Soil structural quality degradation by the increase in grazing intensity in integrated crop-livestock system
ABSTRACT The intensification of soil use, as in integrated croplivestock system (ICLS), might promote soil structural degradation. A field method to evaluate the soil structural quality is the Visual Evaluation of Soil Structure (VESS). Studies on the application of this method to ICLS are few. This work aimed to evaluate the structural quality of a Dystrude

7. High fire temperature changes soil aggregate stability in slash-and-burn agricultural systems
ABSTRACT Fire is a key controlling factor in ecosystem dynamics worldwide, especially, in tropical areas under slash-and-burn agricultural systems. Farmers use fire as a tool to clean the land, and benefit from nutrient enrichment from ash-soil heating. However, fire can cause some detrimental effects on soil systems, such as organic carbon depletion, increa

8. Magnetic Susceptibility of Soil to Differentiate Soil Environments in Southern Brazil
ABSTRACT The interest in new techniques to support digital soil mapping (DSM) is increasing. Numerous studies pointed out that the measure of magnetic susceptibility (MS) can be extremely useful in the identification of properties related with factors and processes of soil formation, applied to soil mapping. This study addressed the effectiveness of magnetic

9. Changes in Soil Organic Carbon Fractions in Response to Cover Crops in an Orange Orchard
ABSTRACT The cultivation of cover crops intercropped with fruit trees is an alternative to maintain mulch cover between plant rows and increase soil organic carbon (C) stocks. The objective of this study was to evaluate changes in soil total organic C content and labile organic matter fractions in response to cover crop cultivation in an orange orchard. The

10. Análise da influência da condutividade hidráulica saturada dos solos nos escorregamentos rasos na bacia do rio Guaxinduba (SP) / Analysis of the influence of saturated hydraulic conductivity from soils in the shallow landslides in the Basin of the River Guaxinduba (SP)
The prediction of landslides-prone areas has as fundamental step researching controlling factors and failure mechanisms. Some of these properties, such as the physical and hydrological soil properties are crucial to the instability of slopes subject to intense rainfall events. One of these properties is the saturated hydraulic conductivity, whose behavior ca

11. Avaliação da qualidade da água de chuva e de um sistema filtro-vala-trincheira de infiltração no tratamento do escoamento superficial direto predial em escala real em São Carlos SP / Evaluation of rainfall water quality and a filter-swaleinfiltration trenches system in the treatment of the building direct runoff in real scale in são carlos sp
Several studies cite the pollution of stormwater as equivalent and sometimes even superior to those found in the sewers. According to this premise and thinking about environmental issues, especially in the contamination of groundwater and the spread of waterborne diseases, the quality of rainwater has become an important focus of study. This work concerns th

12. The resigned qualification: the bad formation of workforce how a structural problem of Brazilian development / A qualificação resignada : A má formação da força de trabalho como um problema estrutural do desenvolvimento brasileiro
This work makes a diagnosis of training policy and professional education system in Brazil. The subject had never been so professional education on the agenda in the sociology of work and labor economics, but came to light at the end of the twentieth century, when the new stage of accumulation explained the decline of Fordism-Taylorism, also denouncing the n
