摘要：

Abstract. Four bullock‐drawn tillage implements (mouldboard plough, chisel plough, sweeps, and shovels) were evaluated on a hard‐setting Alfisol. Measurements included draft requirement, bulk density, cone index, soil crust strength, water content of the plough‐layer and crop yield. Changes in bulk density and cone index due to tillage decreased with time and were negligible by the end of the growing season. After tillage with a mouldboard plough the crust was stronger than after tillage with other implements. The shovel cultivator enabled the soil to store more water, and required least draft per unit effective area of cut. Copyright © 1990, Wiley Blackwell. All rights reserved
