بازیابی وزن مخصوص ظاهری و تخلخل در خاک‌های فشرده‌شده در اثر عملیات چوبکشی با اسکیدرهای چرخ‌لاستیکی با کاربرد مالچ‌های آلی در مسیرهای خروج چوب

However, research on the effect of such treatments on restoring soil properties is scarce. In this research, the effect of organic mulches including leaf litter, rice stubble, and sawdust on the recovery of the physical properties of the compacted soil of logging roads, including soil bulk density and porosity, was evaluated and tested two years after exploitation. The results showed that the treatment of leaf litter, rice stubble and sawdust mulches had a significant effect on the recovery of soil bulk density and porosity. The results showed that litter mulch has the highest amount of effect in restoring the physical characteristics of soil compared to stubble mulch and sawdust. This is despite the fact that the soil texture was not affected by the type and amount of mulch during two years. Also, in the depth of the surface, the effects of mulch are more and significant. It can be concluded that the application of different types of mulches and the increase in the rate of their use causes the recovery and improvement of the physical characteristics of the soil after carrying out logging operations over a period of two years compared to the logging route without treatment. However, the values of soil physical characteristics were still lower than the values measured in the control (untouched) area, which implies that two years is not enough time to restore the soil physical characteristics to the levels before car traffic in the study area.
