Abstract

The soil hydrophobicity can be understood as soil water repellency or difficulty in wetness. This phenomenon is associated with the covering soil particles and hydrophobic organic compounds reducing the soil sorptivity and hence infiltration of water. The aims of this study were to determine the level of hydrophobicity in the soil and assess its relationship with resistance and size distribution of water stable aggregates, particle size distribution and organic matter content of different soils in southern Brazil. Undisturbed soil samples were collected in different soil layers, 0-5, 5-10 and 10-20 cm, to determine soil sorptivity, geometric mean diameter and aggregate stability index while granulometric composition and organic matter content were determined using disturbed soil samples.
