Abstract:
The effect of adsorbed Mg and Ca ions on the infiltration rate (IR) of two montmorillonitic soils (Calcic Haploxeralf and Typic Rhodoxeralf) at several kinetic energies of water drops was studied. The kinetic energy of the water drops, the type of adsorbed ion and the electrolyte concentration in the applied solution all have a strong effect on the IR of the soils saturated by Mg or Ca ions. The higher IR values of the soils exposed to electrolyte solution suggests that clay dispersion takes place in Mg and Ca soils exposed to deionized water from simulated rainfall. -from Author
