The minimum-disturbance treatment produced high soil strength, aggregate stability and bulk density; lowest bulk density occurred in the intermediate treatment. Water infiltration in the field increased with decreasing disturbance, but in all treatments was reduced by sheep grazing the site; infiltration differences appeared to reflect propensities to compact and form crusts
