  • , and ethanol percentage, EP, tests). Water repellency was measured on the surface and at soil depths of 2 cm and 5 cm for 3 fine textured soil types (Rendzic Phaeozem, Hypercalcic Calcisol, and Eutric Cambisol) developed below different plant covers (mossy pine
  • forest, evergreen oak forest, and meadow, respectively). At the class level, WDPT and EP tests offered similar results for unaltered and sieved samples. Differences in the wettability has been observed between soil depths and soil types.
  • , organic matter contents and pH levels. In the field, the actual water repellency was determined using the Water Drop Penetration Time Test (WDPT) but the same test was used to determine the potential water repellency after drying process for several days
  • by the Water Drop Penetration Time (WDPT) test and Fourier Transform-Infrared (FT-IR) analysis was applied to characterise sample chemical composition. Ash water repellency varied from wettable to severely water repellent and differed in terms of maximum WDPT
