Tillage effects on soils: physical and hydraulic responses to direct drilling at Lockhart, N.S.W. [New South Wales; wheat] - 1986 - Printed
3 graphs, 7 tables, 20 ref. Summary (En)
On 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
