Caracterizaçao dos fatores que interferem no processo de repelencia à água em s...
Cambronero, Yorleni ChangO objetivo do trabalho foi avaliar a repelência à água em amostras de solos constituídos em laboratório com diferentes teores de matéria orgânica. Para caracterizar o grau de repelência do solo à água amostras de solo com diferentes texturas e teores de matéria orgânica constituídos em laboratório foram tratadas com 2 concentrações de extrato hidrofóbico e uma testemunha, para medir a repelência foi utilizado o...
Water repellency of sandy soil as a function of hydrophobic concentration
Cambronero, Yorleni Chang; Maia, Claudia Maria Branco de Freitas; Dedecek, Renato Antônio; Hansel, Fabrício AugustoSoil water repellency has been reported worldwide being most extremes cases observed in sandy soils. Soil water repellency is accepted to be caused by recovering of soil particles by hydrophobic compounds originated from plant decomposition. This work aimed to evaluate the influence of concentration of hydrophobic extracts from a forest soil under Pinus taeda on water repellency of sandy soil with differe...
Hydrophobicity of an Entisol under loblolly pine (Pinus taeda) plantation
Maia, Claudia Maria Branco de Freitas; Fukamachi, Cristiane Regina Budziak; Cambronero, Yorleni Chang; Dedecek, Renato Antônio; Mangrich, Antônio SálvioThe understanding of soil carbon stabilization processes can be very useful in the development of mitigation techniques for CO2 emissions and global warming. The greater the hydrophobicity of soil organic matter the more stabilized soil organic carbon. Therefore, hydrophobicity can be a sensitive index to characterize the ‘quality’ of soil organic matter. In this context, the present work aimed to characterize...
