The aims of this study were to investigate the effectiveness of clay mulches (Bentonite and Zeolite) on wind erosion. Soil was homogenously filled into metal trays. Clay mulches i.e. bentonite at two rates (100 and 200 g + 1000 ml water; B1 and B2), and zeolite at two rates (100 and 200 g + 1000 ml water, Z1 and Z2), and control (1000 ml water) in three replications were prepared. Then the mulches were sprayed on soil surfaces of the trays. Wind speed of 85 km h-1 was applied to treatments for 20, 40 and 60 minutes. Based on analysis of variance the effect of mulch, time and interaction effect of them on soil erosion content were significant at p < 0.01. Comparison of means showed that clay mulches significantly reduced the soil erosion content in relation to the control, and Z1, Z2, B1, and B2 treatments had no significant difference (p < 0.05).
