| 摘 要： | This study was carried out at Sand Dunes Stabilization Researches Station in Baiji district (230km north of Baghdad,Iraq) to evaluate the effects of local soil conditioners manufactured from oil derivatives and plant residuals on sand dunes fixation as the first step for sand dunes stabilization.The results indicate that the fuel oil has the first place in improving wind erosion parameters in the study area,such as increasing mean weight diameter,dry aggregates percentage,the needed time for complete disaggregation by dry sieving,and decreasing the disaggregation rates.Bitumen emulsion occupies the second place ,while the plant residuals occupies the third place and has slight effects on the studied pa-rameters.Effects of conditioners on natural vegetation cover are negative in oil derivatives treatments,while positive in plants residuals treatments.

| Abstract: | This study was carried out at Sand Dunes Stabilization Researches Station in Baiji district (230 km north of Baghdad, Iraq) to evaluate the effects of local soil conditioners manufactured from oil derivatives and plant residuals on sand dunes fixation as the first step for sand dunes stabilization. The results indicate that the fuel oil has the first place in improving wind erosion parameters in the study area, such as increasing mean weight diameter, dry aggregates percentage, the needed time for complete disaggregation by dry sieving, and decreasing the disaggregation rates. Bitumen emulsion occupies the second place, while the plant residuals occupies the third place and has slight effects on the studied parameters. Effects of conditioners on natural vegetation cover are negative in oil derivatives treatments, while positive in plants residuals treatments. |
