The influence of vegetation on soil water repellency-markers and soil hydrophobicity

shows that in an ecosystem with oak, grasses and sedges, the roots of various plant species distribute differently in the top- and subsoils. The soil water repellency was measured using water drop penetration time test. The soils were extracted sequentially and soil water repellency markers, e.g., C22 ω-hydroxy fatty acid and C24 α,ω-dicarboxylic acid, were observed mainly derived from plants.196
