Study is focused on the visualization of the preferential flow in different soil types and their horizons using the dye tracer experiment. The field ponding dye infiltration experiments were performed in two soil types: Haplic Luvisol and Haplic Cambisol. In addition, the thin soil section were made and micromoprphological images were used to study soil aggregate structure and dye distribution in microscale. Images of the dye patterns (taken in macro- and micro-scales) documented very different nature of the preferential flow in different soil types and also within the soil profiles.
