Abstract (in english)
   The impact of varying soil micromorphology on soil hydraulic properties and consequently on water flow and herbicide transport is demonstrated on three soil types. The micromorphological image of humic horizon of Haplic Luvisol shows higher order aggregates. The micromorphological image of humic horizont of Greyic Phaeozem shows the relatively homogeneous matrix structure with many pores less than 100 micrometers and a system of larger pores. Aggregates in humic horizont of Haplic Cambisol are purely developed. The soil water properties reflect the pore-size distribution studied using the image analysis. The chlorotoluron mobility in the monitored soils increases as a follows: Haplic Luvisol< Haplic Cambisol< Greyic Phaeozem. Preferential flow slightly affected the herbicide transport. Large gravitational pores that may transport water under saturated conditions were not active during the monitored period.
