Abstract A model based upon concepts of multispecies ion chromatography and mobile-immobile water was developed to simulate the leaching of major soil cations during steady, continuous infiltration of electrolyte solutions into soil columns. The model assumes that a fraction of exchange sites is readily accessible to the mobile solution located in large intra-aggregate pores and that the remaining slowly accessible exchange sites are located in the immobile solution inside smaller pores within aggregates. Ion exchange is assumed to occur instanteously for all of the partitioned exchange sites. Diffusive transfer of ions between the mobile and immobile solution phases results in a time lag for cation leaching from the two compartments of exchange sites, as well as early breakthrough for ion concentration in effluent flowing from the soil column.
