英文摘要	Wind erosion is one of the significant causes of soil and environmental degradation in arid and semiarid regions. Mulching is the most prevailing management scenario which applies to preserve the soil against erosive forces. In this study, effects of different organic and mineral mulches including O-Mulch (Organic-Mulch) at three levels: O1: 1% sugarcane bagasse biochar + 0.5% Arabic gum + 0.5% gelatin; O-2: 3% sugarcane bagasse biochar + 1% Arabic gum + 1% Gelatin; O-3: 5% combination of sugarcane bagasse biochar + 1.5% Arabic gum + 1.5% gelatin), M-Mulch (Mineral-Mulch, Natural white powdery substance) (at three levels: M-1: 1%, M-2: 3% and M-3: 5%) and H-Mulch (Hydrogel-Mulch with Nano silica) (at three levels: H-1: 0.5%, H-2: 1% and H-3: 1.5%), on soil physical and mechanical properties evaluated. The experiment performed in a completely randomized design with three replications. This study accomplished in the Koopal area located in the southeast of Khuzestan Province, Iran Country. The treatments applied to the soils in the plots of 50 x 30 x 5 cm at 75% of field capacity, then incubated for two and four months. After incubation, plots exposed to the open-jet Wind tunnel for 10 min at a speed of 21 m/s on 15 cm above the surface. Analysis of variance revealed that the effect of different levels of treatments on soil physical and mechanical properties in both two and four-month incubation was significant (P < 0.01). Our results illustrated that with increasing mulch levels, the organic carbon (OC), mean weight diameter (MWD), penetration resistance (PR), shear strength (SS), and tensile strength (TS) significantly increased. Moreover, with enhancing mulch application levels to the soil, friability index (FI), soil texture index (STI), and crusting index (CI) decreased meaningfully (P < 0.01). Regarding the effectiveness of mulching on soil physical and mechanical properties, the soil loss diminished. Results confirmed that O-Mulch at all levels, H Mulch and M-Mulch at the highest levels, had the best effect on soil loss mitigation because of their improving effects on soil characteristics. Generally, the applied treatments resulted in declining of soil erosion by increasing aggregate stability, creating a protective layer, and armoring effect on the soil surface.
