The 100 (Haplic Luvisol) and 50 (Haplic Cambisol) litres of solute of dye Brilliant Blue FCF (5 g/litre) was infiltrated on a 1x1 m plot (applying an initial ponding depth of 10 and 5 cm, respectively) immediately after the wheat harvest. The 3-D image od the dye distribution was created. In addition, the thin soil section were made and micromorphological images were used to study a soil aggregate structure and dye disrtibution in microscale. Images of the Haplic Luvisol showed that while dye tracer was partly regularly transported and only some isolated domains were visible in the surface Ap1 horizon, the preferential flow occured in the subsurface horizons. Images of the Haplic Cambisol showed that dye tracer transport in the Haplic Cambisol was in all horizons (Ap, Bw, C) mainly affected by the preferential flow caused by the gravitational fractures and biopores.
