| Outline of Final Research Achievements |
Soil compaction by forestry machinery significantly affected on soil hardness and water content, however the effects of logging slash disposal and skid trails on soil hardness and water content were smaller than the effect of forestry machinery. The effects of soil compaction were mitigated within 10 years after clear-cutting.
According to laboratory incubation experiment used larch plantation forest soils at Hokkaido, net nitrification were not occurred in soils with strong compaction and irrigation treatments but occurred in control, suggesting denitrification could occurred probably due to low soil oxygen content by soil compaction and irrigation. However there were no clear effects of soil compaction on microbial community structure. According to laboratory incubation experiment used soils collected from broad area along Japanese archipelago, the response to soil compaction changed widely site by site.
