Impact of varying soil structure on transport processes in different diagnostic horizons of three soil types

Popis výsledku v původním jazyce

When soil structure varies in different soil types and the horizons of these soil types, it has a significant impact on water flow and contaminant transport in soils. This paper focuses on the effect of soil structure variations on the transport of pesticides in the soil above the water table Transport of a pesticide (chlorotoluron) initially applied on soil columns taken from various horizons of three different soil types (Haplic Luvisol, Grayic Phaeozem and Haplic Cambisol) was studied using two scenarios of ponding infiltration. The highest infiltration rate and pesticide mobility were observed for the Bt1 horizon of Haplic Luvisol that exhibited a welldeveloped prismatic structure. Thelowest infiltration rate was measured for the Bw horizon of Haplic Cambisol, which had a poorly developed soil structure and a low fraction of large capillary pores and gravitational pores. Watr infiltration rates were reduced during the experiments by asol structure breakdown, swelling of clay and/or
