Abstract

Wind erosion is problem in recent years has affected many parts of the Iran. Due to the harmful effects of petroleum mulch, polymer and plant mulch is particular importance to reduce the environmental impact of these compounds and solve the problem of soil loss in erosion-prone land. In this study, two types of polymer and plant mulch as soil stabilizer were used in four levels 0, 15%, 30% and 60% on three types of soil from wind erosion sites in Khuzestan. Effect of mulch to reduce soil loss in the wind tunnel at speeds of 8, 10, 13 m/s were examined. The results of experiments were examined with SPSS software performed factorial experiment in a randomized complete block design and Duncan. Statistical analysis showed that the soil treated with both mulch, significantly different from the control soil to reduce soil loss. It also shows that between two types of mulch in terms of impact on the reduction of soil loss is not significant difference, But the mulches used in various concentrations are significantly different from the one percent level. Results Effect of polymer and plants mulch (both liquid) showed that the use of polymer mulch could well be Decrease the soil loss at speeds of 8, 10 and 13 m/s. Also, mulch plants, reduced the soil loss in the Agricultural soil Abdolkhan area and Hoveyzeh area. But in the land of sand Borvayeh area, this mulch, Had not a positive impact on reducing soil loss in low concentrations.
