5. Conclusions
- The values of soil physical and chemical properties in litter, straw and sawdust treatments were significantly restored as compared with the values in the UNT but were still different from the values of the control treatment (UND).
- According to the current results, a 2-year period is not enough to return the soil physical and chemical properties to pre-traffic levels (using values measured in the control area or intact as a reference point) and a period of more than 2 years is needed for restoring soil properties.
- The present study shows that organic mulch spread on the surface of mineral soil in the skid trails after machine traffic acts as a fertilizer to accelerate the decomposition of organic matter.
- In general, the litter mulch with application levels of 6.2–12.2 Mg ha−1, straw mulch with application levels of 3.8–7.6 Mg ha−1 and sawdust mulch with application levels of 22.2–33.3 Mg ha−1 can be applied as an optimal level for spreading on skid trails to amend soil quality.
