It is widely recognized that organic matter contributes to the hydrophobic characteristics of soils. . The alteration of mineral surfaces by natural organic matter directly impacts waterdriven geochemical processes in terrestrial environments, such as the transport and fate of contaminants. Badía et al. observed differences in soil hydrophobicity among organic matter-rich soils under various vegetation types. Soils beneath pine showed the highest water repellency (i.e., more hydrophobic), whereas soils under meadow exhibited the lowest repellency. Franco et al. demonstrated that the primary contributor to hydrophobicity in South Australia's sandy soils is a polar wax, structurally similar to those found in regional plant materials, such as eucalyptus trees. Similarly, Jiménez-Morillo et. al. suggested that the intensity of soil water repellency is correlated with both the quantity and quality of soil organic matter, particularly the content of fatty acids. In contrast, non-saponifiable lipids showed no association with soil hydrophobicity.
