Description	On the experimental area there is a research project in progress with the aim to optimize the drip irrigation and nitrogen fertilization of potatoes.. The soil profile, composed of Cambisols with high ratio of clay particles, exhibits fast preferential flow caused by macropores and parent rock heterogeneities. The simulation of the soil water suction field was done by means of S_1D_DUAL code, based on the dual-permeability approach. To simplify the description of spatial variability the scaling was applied. The model input parameters were determined inversely with application of parameter estimation software PEST. The comparison of results of the simulations of the both, single and dual domain approaches, demonstrates the significance of preferential pathways on the water regime. Low rainfall intensities do not remarkable affect the water regime of the middle layers of the soil horizon.
