“…1f). These processes, apart from such factor as redox conditions, are affected by pH, organic matter content and temperature, but also cultivation and erosion, thus this is more evident in the topsoil (Davranche and Bollinger, 2000;Li and Richter, 2012). Probably, with ongoing gleization here, the beginning of brunification or lessivage processes is occuring, which appears to be resulting from accumulation of iron (Chojnicki, 1993(Chojnicki, , 2004Zagórski, 2001).…”

Forms of iron as an indicator of pedogenesis in profiles of selected soil types of the northern area of kujawsko-pomorskie province, PolandAbstract: The aim of the study was to determine types of soil-forming processes of the selected soils of Northern Poland, basing on the content and profile distribution of iron forms, and the calculated indicators of pedogenesis. The results confirmed the previous statements on the basis of morphological and textural analyses, hypothesis of soils genesis, thereby proving the usefulness of this kind of research in determining these processes. This research showed the beginning of brunification process in the Endogleyic Phaeozem, unnoticed in textural and morphological analysis, in which only the gleization process was previously identified. The content and distribution of iron forms (Fe d , Fe o , Fe c , Fe s ) in the profiles of the studied soils were characteristic for the type of soil and soil-forming process.

“…However, legacy effects of land use induced degradation are spatially heterogeneous, varying by land cover type [14][15][16] and topography [17]. Given the spatiotemporal complexity of land degradation, there is a need for improved analytical resolution in analyses of land use change [18].…”

Processes of land degradation and regeneration display fine scale heterogeneity often intimately linked with land use. Yet, examinations of the relationships between land use and land degradation often lack the resolution necessary to understand how local institutions differentially modulate feedback between individual farmers and the spatially heterogeneous effects of land use on soils. In this paper, we examine an historical example of a transition from agriculture to forest dominated land use (c. 1933-1941) in a highly degraded landscape on the Piedmont of South Carolina. Our landscape-scale approach examines land use and tenure at the level that individuals enact management decisions. We used logistic regression techniques to examine associations between land use, land tenure, topography, and market cost-distance. Our findings suggest that farmer responses to changing market and policy conditions were influenced by topographic characteristics associated with productivity and long-term viability of agricultural land use. Further, although local environmental feedbacks help to explain spatial patterning of land use, property regime and land tenure arrangements also significantly constrained the ability of farmers to adapt to changing socioeconomic and environmental conditions.

“…Transformation can be perceptible within a few years or decades, as it has already been observed following land-use changes (e.g. Li and Richter, 2012;Richter and Yaalon, 2012). Some vegetation communities have commonly been observed in association with specific soil types (Lundström et al, 2000, Mourier et al, 2010, Willis et al, 1997.…”

“…Land-use changes or ecosystem shifts can have a wide range of impacts on soil properties such as nutrient availability, organic matter content, soil structure, erosion or soil water repellency (Li and Richter, 2012;Van der Putten et al, 2013;Willis et al, 1997). Concurrently, soil properties are of great importance for vegetation establishment and maintenance in space and time (Kardol et al, 2006).…”

“…Because iron complexation with organic compounds is a dominant process in podzolic B mineral horizons and is sensitive to properties such as soil pH, organic matter content or soil erosion (Holmgren, 1967;Li and Richter, 2012;McBride, 1987), we also hypothesised that the podzolisation process and hence iron reactive chemical species would be different depending on the local vegetation density. We assumed that the conditions found in soils covered by a lichen mat with low-density canopy would be more prone to iron and aluminium oxide accumulations than MF soils.…”

Boreal coniferous forest density leads to significant variations in soil physical and geochemical properties

Abstract. At the northernmost extent of the managed forest in Quebec, Canada, the boreal forest is currently undergoing an ecological transition between two forest ecosystems. Open lichen woodlands (LW) are spreading southward at the expense of more productive closed-canopy black sprucemoss forests (MF). The objective of this study was to investigate whether soil properties could distinguish MF from LW in the transition zone where both ecosystem types coexist. This study brings out clear evidence that differences in vegetation cover can lead to significant variations in soil physical and geochemical properties.Here, we showed that soil carbon, exchangeable cations, and iron and aluminium crystallinity vary between boreal closed-canopy forests and open lichen woodlands, likely attributed to variations in soil microclimatic conditions. All the soils studied were typical podzolic soil profiles evolved from glacial till deposits that shared a similar texture of the C layer. However, soil humus and the B layer varied in thickness and chemistry between the two forest ecosystems at the pedon scale. Multivariate analyses of variance were used to evaluate how soil properties could help distinguish the two types at the site scale. MF humus (FH horizons horizons composing the O layer) showed significantly higher concentrations of organic carbon and nitrogen and of the main exchangeable base cations (Ca, Mg) than LW soils. The B horizon of LW sites held higher concentrations of total Al and Fe oxides and particularly greater concentrations of inorganic amorphous Fe oxides than MF mineral soils, while showing a thinner B layer. Overall, our results show that MF store three times more organic carbon in their soils (B+FH horizons, roots apart) than LW. We suggest that variations in soil properties between MF and LW are linked to a cascade of events involving the impacts of natural disturbances such as wildfires on forest regeneration that determines the vegetation structure (stand density) and composition (ground cover type) and their subsequent consequences on soil environmental parameters (moisture, radiation rate, redox conditions, etc.). Our data underline significant differences in soil biogeochemistry under different forest ecosystems and reveal the importance of interactions in the soil-vegetation-climate system for the determination of soil composition.
