摘要

Wind erosion is a common environmental problem in most of the arid and semi-arid regions of the world. Although anthropogenic soil disturbance has always been an influential factor intensifying the natural process of aeolian land form evolution and dust emissions around the world (Xu, 2006; Okin et al., 2001) and in inland drift-sand areas of Turkey (Buyuk et al., 2011), comprehensive understanding on this subject is still missing. Tegen and Fung (1995) estimated that 20-50% of the global dust load is initiated from human-disturbed soils. The objective of this study was to examine the impact of two tillage practices, reduced tillage (RT) and conventional tillage (CT), at the beginning of the windy season on sediment transport on a sandy-loam soil surface in Karapinar, Turkey. Employing the conventional tillage system combined with fallow periods in wheat cultivation in semi-arid regions of central Anatolia has been identified as a suitable practice to restore the soil moisture content. During the fallow phase of the cropping system multiple moldboard or disk plowings are usually performed to increase the soil percolation and water storage capacity. Conventional tillage buries residues and stalks, and likewise removes the natural plant cover that has been emerged on the surface after the last tillage application. The coincidence of the spring tillage and severe spring winds in fallow periods has been determined to be the major reason for soil losses from these croplands.
