Study sites included three pastures which had been grazed at the same intensities for 53 years. After 1 year there were changes in the initial dry run equilibrium runoff ratio on the area that had been heavily grazed. No changes were evident in the final wet-wet equilibrium runoff ratios after 2 years. These results indicate that changes in the infiltration parameters of the surface soil layers occur within 2 years after removal of cattle grazing but no changes occurred at the deeper soil depths, which affect long-term equilibrium infiltration. Wet-wet equilibrium runoff ratios decreased on the light and moderate grazed areas over the 3-year time span.
