O článku:
The paper examines the impact of the interface depth between the superimposed organic horizon and the organomineral A- horizon of forest soil on the water infiltration from the Guelph infiltrometer into forest soil. The superimposed organic horizon forms the surface layer of forest soil and it has specific physical properties such as high porosity, low bulk density, released structure and high values of hydraulic conductivity. The decomposing organic matter of the superimposed organic horizon causes the water repellency of organomineral A-horizon lying under it. In model Hydrus 2D/3D simulations with different interface depths between the superimposed organic horizon and the organomineral A-horizon of forest soil a slowdown of vertical component of infiltration from the Guelph infiltrometer and a preference of horizontal component of infiltration was detected in the case when the interface was in the bottom of borehole in which the Guelph infiltrometer was located, or when the interface has been moved higher than the bottom of borehole. By the increase of interface above the bottom of borehole, the increase of saturated hydraulic conductivity value from Ks=0.0041 cm s-1 to Ks=0.109 cm s- 1 was detected.
