Abstract	During soil solute transport events, preferential flow paths generate gradient concentrations between fast and slow moving regions dominated by different pore water velocities. Under stationary water flow conditions, advection and mechanical dispersion are the controlling mechanisms. Under a periodic irrigation regime, amid irrigation events, water flow decreases and solutes become more uniformly distributed through the soil regions due to diffusion. In this work, a leaching experiment is carried out, consisting of 8 short irrigation events after application of Pentafluoro-Benzoic acid as a non-sorbable tracer. Effluent composition and volumes are used to study the concentration perturbations in the breakthrough curve. Results obtained with the application of this technique can give practical conclusions on model development and application, as well as metyhodological conclusions in scale chage from column to field experiments.
