“…Our present data ( Fig. 4; Table 3) are similar to previous work by Sutinen et al (2006) showing a significant decrease in the soil EC a in a descending micro-site order; EC aUTR =0.70±0.04 mSm −1 , EC aTILT =0.57± 0.05 mSm −1 and EC aTRENCH =0.34±0.03 mSm −1 , respectively. Also, the soil EC wUTR =6,5±1.4 mSm −1 and EC wTILT =7.0±2.1 mSm −1 found in Sutinen et al (2006), was also confirmed here, such that EC wUTR = 11.7±9.1 mSm −1 and EC wTILT =10.7±9.2 mSm −1 were obtained (Fig.…”

“…Hence the root- (Giesler et al 2005). The MSP inversion of soil horizons (Pohtila 1977;Hunt and McMinn 1988;Örlander et al 1990) has short-term soil effects (Van Cleve and Dyrness 1983;Jurgensen et al 1997;Haeussler et al 1999;Simard et al 2003), but also contributes to the long-term soil physico-chemical dynamics (Vitousek and Matson 1985;Tanskanen and Ilvesniemi 2004;Sutinen et al 2006;Figs. 4 and 6).…”

“…Scots pine, seedlings in their early stages (<6 years;Pohtila 1977), yet the performance and stabilisation of the plantations strongly depend on the site types within the first 20 years (Hansson and Karlman 1997;Witzell and Karlman 2000). Mechanical site preparation is unable to guarantee a long-term reduction in the soil water content (>15 years; Elliott et al 1998;>23 years;Sutinen et al 2002aSutinen et al , 2006. Rather, soil physical properties outweigh the impact of MSP, such that temporal stability of spatial patterns (time stability) of measured soil water content does not alter via MSP (Vachaud et al 1985;Van Pelt and Wierenga 2001;Sutinen et al 2007a).…”

“…In this study, we assessed soil quality at spots of Norway spruce seedlings/saplings by the soil solute content obtained with terrestrial galvanic measurements of soil electrical conductivity (EC a ) (see Rhoades and Oster 1986;McBride et al 1990;Puranen et al 1999;Sutinen et al 2006;Närhi et al 2010a). McBride et al (1990) found EC a at red oak (Quercus rubra L.) sites to be strongly correlated with soil attributes associated with forest soil quality, such as exchangeable Ca, Mg and CEC.…”

The northern boreal forests in Fennoscandia have been managed for decades using clear-cut harvesting and subsequent mechanical site preparation (MSP). MSP is intended to reduce competing vegetation, improve soil temperature and water conditions as well as mobilize nutrients for the use by outplanted seedlings. The use of heavy machinery, particularly bulldozerdriven Marttiini-plough, has raised concerns about soil quality and therefore sustainability of forest productivity and forest floor diversity. We applied soil physical measurements and inventories of naturally established Norway spruce (Picea abies (L.) Karst.) to investigate these concerns 16-18 years after intensive forest management in Finnish Lapland. MSP with Marttiiniplough had inverted Podzol soil profile and created the following micro-sites: trench, tilt and untreated (UTR) soil between the ploughed tracks at former spruce sites. The soil electrical conductivity (EC a ) and soil solution conductivity (EC w ) at micro-sites of spruce seedling/ saplings, differed significantly (p<0.001). The majority of spruce individuals (60%) were established on UTR (mean EC a =0.54±0.34 mSm −1 ), while the proportion on tilt was minor (34%, EC a =0.35±0.18 mSm −1 ) and almost absent on trench (6%, EC a =0.12±0.11 mSm −1 ). In a similar way, the soil quality decreased such that EC wUTR = 11.7 ± 9.1mSm −1 > EC wTILT = 10.7 ± 9.2mSm −1 > EC wTRENCH = 2.2 ± 2.9mSm −1 . Spruce individuals at UTR (mean height 127±89 cm) and tilt (111±74 cm) were significantly (p<0.001) taller compared to those in trench (32±44 cm). The five study sites were surrounded by mature Norway spruce stands, yet only 0-14% of spruce seedlings/ saplings were found on the MSP-exposed mineral soil. These results imply that intensive forest practices result in losses in soil nutrient supply, hence endangering sustainability of the soil quality, and therefore occasionally hamper natural regeneration of Norway spruce.

“…The median soil Ca:Al ratio was only 0.02, indicating, according to general theory, considerable risk for aluminium stress. A significant long-term decrease of soil EC b , correlating with Ca concentration, has been observed after mechanical site preparation in the study area (Sutinen et al 2006). To maintain long-term forest productivity and to prevent eutrophication of waters due to leaching of nutrients, it is important to find methods for suitable mechanical site preparation.…”

To focus conservation efforts into forest areas with high biodiversity, more information is needed about soil-vegetation dependencies in Finnish Lapland. We studied understory vegetation and soil variables along a transect across a felsic-mafic lithological sequence in central Finnish Lapland. At 119 northern boreal forest sites, coverages of understory vegetation, several mineral soil chemical elements, soil electrical conductivity, pH, and dielectric permittivity, as a measure of soil volumetric water content, were measured. We found that soil Ca concentration and Ca:Al ratio were the main variables determining vegetation composition and diversity. Ca-rich soils were characterised by high electrical conductivity, pH, and Mg concentration, and by low concentration of Al, S, Zn, and low C:N ratio. Soil Ca concentration is a diagnostic measure of plant diversity as concentration higher than 100 mg kg -1 resulted in a considerable increase in plant diversity. Sites with Ca concentration this high were rare, and probably important in maintaining high biodiversity. The median soil Ca:Al ratio was only 0.02, suggesting, according to general theory, a considerable risk for aluminium stress. We found Geranium sylvaticum and Rubus saxatilis to be good indicators for Ca-rich regimes and high plant diversity.
