Beech as the most-abundant tree species in Slovakia has a tendency to form a compact humus layer with specific structure, leading to a reduction in the soil surface infiltration area and a significant influence on the preferential flow generation. The research was carried out in beech forests with different forest stand density in the Vtáčnik Mountain (Central Slovakia). The maximal infiltration surface area 35.11 ± 6.58% of sand surface infiltration area was reached at the plot A (0.8).
