Název v původním jazyce

The impact of vegetation on hydraulic conductivity of sandy soil

Popis výsledku v původním jazyce

The objective of this study was to assess an impact of vegetation on the hydraulic conductivity of sandy soil at the locality Mláky II at Sekule (southwest Slovakia). It was found that the unsaturated hydraulic conductivity kr(?2 cm) reduced due to the soil water repellency increased in the same order: Forest soil < Glade soil Meadow soil < pure sand, as there decreased the water drop penetration time tp: Forest soil > Glade soil Meadow soil > Pure sand, which could refer to an inverse proportionality between the capillary suction and hydrophobic coating of soil particles. The saturated hydraulic conductivity Ks increased in the order as follows: Meadow soil < Glade soil Forest soil < Pure sand, and more than two-times higher Ks at both the Forest andGlade sites than that at the Meadow site could be a result of both the patchy growth of vegetation with some areas of bare soil at the Glade site and the macropores (dead roots) in more homogeneous humic top-layer at the Forest site.
