Impact of forest management and soil compaction on soil GHG fluxes of a temperate forest

摘要: Temperate forests are a considerable sink for methane (CH4), carbon dioxide (CO2) and the emissions of nitrous oxide (N2O) and nitric oxide (NO) are low. Apart from the tree species composition, forest management itself can have a significant long-term influence and act as a driver on the GHG budget, particularly through soil compaction. To assess the impact of tree species composition, thinning and soil compaction on the GHG budget, we measured GHG soil fluxes in a one-year campaign in a forest located in the catchment of the" Münichbach", south-west to Vienna, Austria (N 48 07'16", E 16 02'52'', 510 m MASL). The soil is classified as Dystric cambisol over sandstone which is known to be sensitive for compaction and has a low recovery capacity. The mean air temperature in the campaign year (2019) was 9.7 C and the annual precipitation was 820 mm. The experimental setup consisted of four treatments …
