520 _aOn a red-brown earth 3 systems were applied over 3 years of wheat cropping: in order of decreasing "disturbance", cultivated fallow, direct drilling, and direct drilling with narrow points. 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
