“…Results from Jaunlelgava sites show significant increase in the soil penetration resistance due to soil compaction up to 80 cm deep. The results confirm the view expressed in other studies that soil compaction caused by logging machinery in sandy soils is more than 70 cm deep [1]. The study site in Ogresgals is more fertile than the sites in Jaunjelgava and default soil penetration resistance is lower because of smaller soil particle sizes.…”

The aim of the study is to evaluate the impact of forest harvesting machinery on soil compaction in technological corridors and on water exchange. The study area consists of 6 study plots on sandy and moraine loam sediments. Each study site is 400 m 2 large and consists of a 20 m long technological corridor with adjoining areas. Thinning has been done in the study areas in 2016 and technological corridors are made perpendicular to slope of the forest floor. During field works data about soil penetration resistance were collected. Monitoring of the groundwater level was conducted during all study period and soil samples were collected to analyse the soil water permeability. The study concludes that, due to logging, there are significant signs of soil compaction in technological corridors. In the study sites on the sandy sediments the greatest compaction effect is observed in the layer from 20-80 cm, while on the moraine loam sediments in the layer up to 20 cm deep. Changes in groundwater levels as a result of soil compaction have not been observed and that may be associated with atypically dry weather conditions during 2018.

“…Several studies [1][2][3] conclude that heavy logging machinery significantly contributes to soil compaction and decreases the amount of macropores in soil, hinders water infiltration and gas exchange, and affects adjacent areas. Significant impact has also been observed on the soil fauna.…”

“…3). A smaller range of pressure heads in the wheel tracks compared to the undisturbed soil is in line with the results presented by Fründ and Averdiek (2016). However, there were no differences found between the water balances of the two microsites, which was expected for the present modeling approach when the same weather data, plant descriptions and groundwater level data were used for both microsites, and the only difference was in the hydrological properties of the upper 0 to 5 cm of the mineral soil.…”

“…During the 2017 growing season, the estimated air‐filled porosity in the wheel tracks was below 0.10 m 3 m −3 on the majority of days at Site T (82%) and one fourth of the days at Site R (23%; Table 3). In the study by Fründ and Averdiek (2016) on skid trails in Germany, no recovery of soil aeration in the 12‐ to 24‐cm depth was found during the first 3 yr after harvester and forwarder traffic. In Finland, the growth of Norway spruce seedlings was reduced when air‐filled porosity was below 0.10 m 3 m −3 (Wall and Heiskanen, 2003); also, when studying mature stands of Scots pine, the growth‐rate was reduced when this threshold was exceeded (Wall and Heiskanen, 2009).…”

“…Wetter conditions in the wheel tracks were indicated by both the measurements with the portable TDR along the slopes and the Ellenberg indicator value F (soil moisture). This is commonly found in soil compaction studies on forestland (Ares et al, 2005;Fründ and Averdiek, 2016;Wei et al, 2016). However, in dry years, the higher water-holding capacity in the wheel tracks may be beneficial for seedlings, as long as the soil is not too compacted for root penetration.…”

Core Ideas Impact of forwarding on soil water and vegetation was investigated after 4 to 5 years. Soil water content was highest in wheel tracks and lowest between tracks. Bare soil was more frequent in tracks and between tracks than in undisturbed soil. In wheel tracks, soil aeration may be restricted in periods with high precipitation. Simulated root‐zone pressure heads showed little variation between microsites. Soil compaction is a common consequence of forestry traffic traversing unprotected, moist soils; it decreases porosity and affects hydraulic conductivity even in coarse‐textured soils. The aim here was to study root‐zone hydrology and vegetation in three microsites (in, between, and beside wheel tracks) 4 to 5 yr after forwarder traffic, on stony and sandy till soils in two clearcuts in northern Sweden. Measurements of soil volumetric water content (VWC), vegetation indicators and one‐dimensional hydrological modeling (Hydrus‐1D) of wheel tracks and undisturbed soil were conducted. Soil VWC was monitored hourly during 2017 and 2018 in three or four plots along a slope on each site. Soil VWC was also measured once with a portable sensor in 117 plots along two slopes at each site, where the vegetation was recorded and analyzed using Ellenberg indicator indexes. Soil VWC was highest in wheel tracks and lowest between tracks; this was corroborated by the species composition in the wheel tracks (Ellenberg indicator for soil moisture). Bare soil was more frequent in wheel tracks and between tracks than in undisturbed soil. The model simulations indicated that the changed soil hydraulic properties influenced the VWC results in the wheel tracks. However, the differences in average pressure heads in the root zone were small between the microsites and only apparent during dry periods. In the wheel tracks, air‐filled porosity was <0.10 m3 m−3, indicating insufficient soil aeration during 82% (Site T) and 23% (Site R) of the 2017 growing season. Insufficient aeration could be one explanation for the presence of some still unvegetated areas.

During mechanized forest operations, machines with high wheel loads are operated directly on the soil and can pose serious concerns for the integrity and quality of soil properties. Simply relying on absolute soil density (g cm −3 or t m −3) as a measure of qualitative assessment remains site specific. Instead of absolute soil density, the aim of this study was to assess and quantify the above-and belowground biomass growth response of Norway spruce (Picea abies [L.] Karst) seedlings exposed to varying relative bulk densities (RBD), expressed as a ratio between field bulk density and maximum bulk density achieved through the standard Proctor test. In the laboratory study, silt loam collected from a forest stand located near Munich, Germany, was placed inside 24 chambers (30.6 cm in length, 8.2 cm in width, and 42.0 cm in height) and compacted layerwise with a hydraulic press until the target RBD levels (0.67, 0.72, 0.77, and 0.82) were reached. After compaction, 120 Norway spruce seeds were sown and growth was monitored for 156 days. Morphologic measurements of 102 seedlings were performed after the growing period where root, shoot, and needle growth characteristics and mass were recorded. Detailed root analysis was performed with the WinRHIZO software, and nutrient analysis was performed on the soil as well as the root, shoot, and needle components of seedlings. Results indicate statistically lower average root (48%), shoot (43%), and needle (43%) mass per seedling for seedlings growing on the RBD 0.82 as compared to those growing on the RBD 0.67. Most analyses revealed no statistical differences between the two lower RBD levels, while statistical differences were detected as the RBD increased to 0.77 and 0.82. The use of RBD as a means of qualitative assessment of soil properties showed promise and should be investigated further for other economically important European tree species, while taking into consideration a longer monitoring period.
