“…The thickness of the Ol and Of + Oh layers was measured in the field (±0.1 cm). We sampled the top 10 cm of mineral soil because tree species have the greatest impact on the uppermost layers of the mineral soil (Augusto et al 2002;Hagen-Thorn et al 2004), and the top 10 cm of mineral soil roughly represents the 35-40 % of the total SOC stock down to 100 cm soil depth in Norway spruce and European beech forests (Galka et al 2014). Moreover, recent studies show that signif icant differences in C sequestration between conifers and de ciduous species over the last decades in French forests have only occurred at the uppermost 20 cm (Jonard et al 2013).…”

Abstract& Key message Combined effects of litterfall and root turnover significantly increase topsoil carbon stocks in Norway spruce and European beech mixed forests, indicating local complementarity effects mediated by tree species mixtures. & Context The establishment of mixed stands by intermingling individuals of European beech and Norway spruce is an ongoing trend in adaptive forest management strategies. However, our understanding of the potential of these strategies to promote C sequestration remains limited. & Aims This study aims to assess the effect of species composition on SOC stock in a mixed forest of Norway spruce and European beech. & Methods We studied C stocks in the uppermost soil layers in two stands dominated either by Norway spruce or European beech and in a mixture of both species. We evaluated the effect of litterfall and root turnover on soil organic carbon (SOC) stocks and its spatial distribution by combining structural equation models and geostatistical techniques. & Results C stocks in the forest floor were highest in Norway spruce, whereas in the mineral soil, the highest values were in the mixed stand. The proportion of Norway spruce litterfall was positively related to C stock in the forest floor across stands. Root turnover was positively related to C stock in the mineral soil of the mixed stand. & Conclusion Our results confirm a contrasting role of root turnover and litterfall between soil layers in the studied stands, suggesting that tree species composition can mediate the spatial distribution of SOC stocks in mixed forests.

“…In the studied soils under dwarf pine shrub, the SOC stock in the O horizon comprised only one-third of the entire SOC stock despite its substantial thickness, which is similar to the results obtained in forest soils in the Stołowe Mts. in southwestern Poland (Gałka et al, 2014).…”

Abstract. The purpose of the paper is to describe soil organic carbon (SOC) sequestration rates in calcareous shallow soils in reforested areas in the Tatra Mountains with a particular focus on different forms of organic matter (OM) storage. Three plant communities creating a mosaic on the slopes of the studied valley were taken into account.Fifty years since the conversion of pastureland to unused grassland, dwarf pine shrub and larch forest have emerged in the study area, along with the development of genetic soil horizons as well as SOC sequestration in the soil despite the steepness of slopes. SOC stock was measured to be the highest in soils under larch forest (63.5 Mg ha −1 ), while in soil under grassland and under dwarf pine shrub, this value was found to be smaller (47.5 and 42.9 Mg ha −1 , respectively).The highest amount of mineral-associated OM inside stable microaggregates (MOM FF3) was found in grassland soil (21.9-27.1 % of SOC) and less under dwarf pine shrub (16.3-19.3 % of SOC) and larch forest (15.3-17.7 % of SOC). A pool of mineral-associated OM inside transitional macroaggregates (MOM FF2) was found in soil under dwarf pine shrub (39.2-59.2 % of SOC), with less under larch forest (43.8-44.7 % of SOC) and the least in grassland soil (37.9-41.6 % of SOC). The highest amount of the free light particulate fraction (POM LF1) was found in soil under dwarf pine shrub (6.6-10.3 % of SOC), with less under larch forest (2.6-6.2 % of SOC) and the least in grassland soil (1.7-4.8 % of SOC).

“…The above-listed fi ndings lead to the conclusion that all archival data of soil pH at soil:solution ratio 1:2.5 can be reliably recalculated using simple linear regression equations to the desired pH values at soil:solution ratio 1:5. Additionally, the differences between pH values at soil:solution ratios 1:2.5 and 1:5, both in distilled water and KCl solution are under this study much smaller or even insignifi cant as compared to the reported pH differences related to fi eld variability [18,29,36,50,51]. Thus, the pH values at soil:solution ratios 1:2.5 and 1:5 may be considered identical (do not require the recalculation), if 1) the natural soil variability is high, or 2) only the pH class is required (as for fertility evaluation), or 3) soil pH is the only accompanying variable (as in monitoring of soil contamination with heavy metals).…”

“…[17][18][19][20]. Changes in soil pH are considered a sensitive indicator of human impacts (from agriculture, industry, urbanization, and others), both as acidifi cation [21][22][23] and alkalization [24][25][26][27][28][29][30]. Soil pH is therefore involved in all soil-oriented studies, inventories, and databases [31][32][33][34], as well as in most environmental monitoring programs [35][36][37][38][39].…”
