Abstract
Today, depending intensive tillage on arid and semi-arid regions, wind erosion is an important environmental problem. Reduced tillage practices are often considered as effective in reducing erosion. In this study, the effects on the wind erosion of different soil tillage applications were examined. Trials were conducted at wind speeds of 13ms-1 in a wind tunnel. After tillage, stubble amount and cover ratio, and mean weighted diameter of soil values were measured. These values were varied from 42.67 to 128 gm-2 for stubble amount, 1.27 to 19.32 % for stubble surface cover ratio and 6.53 to 13.57 mm for mean weighted diameter. At 13 ms-1, sediment transport rates varied from 176 to 1365 gm-2h-1 as depending on different soil tillage. The results showed that the relationships between erosion and shear stress of soil, stubble amount, and mean weighted diameter were found significantly and regression coefficient of relation were R2=0.79, R2=0.95 and R2=0.95 respectively.
