The extent of degraded areas in Brazil, mostly caused by human activities, is increasing. Degradation leads frequently to bare soils, which, due to lack of vegetation cover, are liable to erosion and, therefore, might be the main source of sediments. The objective of this study is to analyze the physical and chemical soil properties of a degraded s...
Chapter
The genesis of soils has been seen mostly as an autochthonistic process, that is, formation in situ. However, soil geomorphologists have recognized addition and loss of materials, for example, through eolian and colluvial processes, as a major contribution to allochthonistic soil formation.The most important characteristic of these soils is the lit...
