“…Furthermore, some studies suggested that C4 herbs are distributed according to altitude (Menot and Burns, 2001;Stevenson et al, 2005;Wang, 2003) and geographic location (Korner, 1991;Wang et al, 2004). In our study the two most common species, Cyperaceae and Poaceae, occur between 3600 m and 6100 m across the central Tibetan Plateau (Table 1), and the result shows no altitudinal relationship with the δ 13 C org values among both C3 and C4 herbs.…”

“…On the other hand, mean δ C soil values could be a function of climatic parameters. Stevenson et al (2005) found an inversely proportional relationship between mean annual precipitation and δ C ratios in soil. Bird et al (2004) concluded the same tendency in Botswana along a 1000-km-long transect.…”

“…Changes in δ C values in the investigated profiles (error bars indicate standard deviation) n = 3-6 (depending on standard deviation) According to the results of Stevenson et al (2005), pedogenic carbonates have significantly higher δ C values within a range of − 4.1 to − 10.8‰ that ensure the possibility of separation of organic and inorganic carbon solely on the basis of stable isotope concentrations. Accordingly, the higher values could be the result of CaCO exhumed from the parent material due to intensive erosion.…”

A 300-year record of sedimentation in a small tilled catena in Hungary based on δ13C, δ15N, and C/N distribution

Purpose Soil erosion is one of the most serious hazards that endanger sustainable food production. Moreover, it has marked\ud effects on soil organic carbon (SOC) with direct links to global warming. At the same time, soil organic matter (SOM) changes in\ud composition and space could influence these processes. The aim of this study was to predict soil erosion and sedimentation\ud volume and dynamics on a typical hilly cropland area of Hungary due to forest clearance in the early eighteenth century.\ud Materials and methods Horizontal soil samples were taken along two parallel intensively cultivated complex convex-concave\ud slopes from the eroded upper parts at mid-slope positions and from sedimentation in toe-slopes. Samples were measured for SOC,\ud total nitrogen (TN) content, and SOMcompounds (δ13C, δ15N, and photometric indexes). They were compared to the horizons of\ud an in situ non-eroded profile under continuous forest. On the depositional profile cores, soil depth prior to sedimentation was\ud calculated by the determination of sediment thickness.\ud Results and discussion Peaks of SOC in the sedimentation profiles indicated thicker initial profiles, while peaks in C/N ratio and\ud δ13C distribution showed the original surface to be ~ 20 cm lower. Peaks of SOC were presumed to be the results of deposition of\ud SOC-enriched soil from the upper slope transported by selective erosion of finer particles (silts and clays). Therefore, changes in\ud δ13C values due to tillage and delivery would fingerprint the original surface much better under the sedimentation scenario than\ud SOC content. Distribution of δ13C also suggests that the main sedimentation phase occurred immediately after forest clearance\ud and before the start of intense cultivation with maize.\ud Conclusions This highlights the role of relief in sheet erosion intensity compared to intensive cultivation. Patterns of δ13C\ud indicate the original soil surface, even in profiles deposited as sediment centuries ago. The δ13C and C/N decrease in buried in\ud situ profiles had the same tendency as recent forest soil, indicating constant SOM quality distribution after burial. Accordingly,\ud microbiological activity, root uptake, and metabolism have not been effective enough to modify initial soil properties

“…According to the chronology suggested by Orombelli and Ravazzi (1996), the development of soils with caranto features outcropping in the Venetian Plain (Giandon et al, 2001;Mozzi et al, 2003;Ragazzi et al, 2004;Bondesan & Meneghel, 2004;Mozzi, 2005) and in the Po Plain (Cremaschi, 1987;Marchetti, 2001Marchetti, , 2002Amorosi et al, 2008) are related to the warm and relatively humid climate during Early and Middle Holocene. Post-glacial climate enhanced local calcification, resulting in the pedogenetic formation of calcareous nodules at depth within the alluvial sequence (Magaldi & Giammatteo, 2008;Stevenson et al, 2005;Zhou and Chafetz, 2010).…”

The caranto paleosol and its role in the early urbanization of Venice

As rising sea level threatens Venice, there is a need to construct a historical framework for interpreting modern environmental changes. Environmental conditions that would later help support Venice's urbanization were established during the Late Glacial period when calcic soils began to develop in the Venetian alluvial paleoplain. A calcic paleosol, buried by Middle to Late Holocene marine transgressive deposits, represents a subsurface layer long known in the Venice area as "caranto." Referenced in the ancient chronicles of architects and builders, the caranto exhibits relatively high compressive and shear strength, making it an important substrate for supporting building foundations, some dating back to the Gothic era (12th-15th centuries A.D.). Hence, the caranto paleosol documents local post-glacial environmental changes while playing an important role in Venetian building construction and human settlement. Here we provide geochemical, sedimentological, paleoecological, and chronological analyses of the caranto paleosol and related deposits based on recent coring of the Venetian Lagoon.
