Gradual drying of permafrost peat decreases carbon dioxide production in drier peat plateaus but not in wetter fens and bogs Soil (IF 5.8) Pub Date : 2025-05-14 Aelis Spiller, Cynthia M. Kallenbach, Melanie S. Burnett, David Olefeldt, Christopher Schulze, Roxane Maranger, Peter M. J. Douglas
Abstract. Permafrost thawing of northern peatlands can cause the local collapse of peat plateaus into much wetter thermokarst bogs and fens, dominated by Sphagnum mosses and graminoids, respectively. However, permafrost thaw can also improve landscape drainage and, thus, lead to the regional drying of peatlands. How gradual drying of these thawing permafrost peatlands affects the subsequent microbial

The clay mineralogy rather than the clay content determines radiocaesium adsorption in soils on a global scale Soil (IF 5.8) Pub Date : 2025-04-29 Margot Vanheukelom, Nina Haenen, Talal Almahayni, Lieve Sweeck, Nancy Weyns, May Van Hees, Erik Smolders
Abstract. The transfer of radiocaesium (137Cs) from soil to crops is the main long-term radiation risk after nuclear accidents. The prevailing concept is that 137Cs sorption in soil – and, hence, its bioavailability – is controlled by soil clay content (0–2 µm). This study tested this assumption using 24 soils collected worldwide. The radiocaesium interception potential (RIP), i.e., 137Cs adsorption

Soil is a major contributor to global greenhouse gas emissions and climate change Soil (IF 5.8) Pub Date : 2024-12-06 Peter M. Kopittke, Ram C. Dalal, Brigid A. McKenna, Pete Smith, Peng Wang, Zhe Weng, Frederik J. T. van der Bom, Neal W. Menzies
Abstract. It is unequivocal that human activities have increased emissions of greenhouse gases, that this is causing warming, and that these changes will be irreversible for centuries to millennia. Whilst previous studies have broadly examined the contribution of agriculture or land use change to anthropogenic greenhouse gas emissions, the contribution of soil itself remains unclear, with quantifying

Uncovering soil compaction: performance of electrical and electromagnetic geophysical methods Soil (IF 5.8) Pub Date : 2024-12-04 Alberto Carrera, Luca Peruzzo, Matteo Longo, Giorgio Cassiani, Francesco Morari
Abstract. Monitoring soil structure is of paramount importance due to its key role in the critical zone as the foundation of terrestrial life. Variations in the arrangement of soil components significantly influence its hydro-mechanical properties and therefore its impact on the surrounding ecosystem. In this context, soil compaction resulting from inappropriate agricultural practices not only affects

Freeze–thaw processes correspond to the protection–loss of soil organic carbon through regulating pore structure of aggregates in alpine ecosystems Soil (IF 5.8) Pub Date : 2024-12-04 Ruizhe Wang, Xia Hu
Abstract. Seasonal freeze–thaw processes alter soil formation and lead to changes in soil structure of alpine ecosystems. Soil aggregates are basic soil structural units and play a crucial role in soil organic carbon (SOC) protection and microbial habitation. However, the impact of seasonal freeze–thaw processes on pore structure and their impact on SOC fractions have been overlooked. This study characterized

The clay mineralogy rather that the clay content determines radiocaesium adsorption in soils Soil (IF 5.8) Pub Date : 2024-12-03 Margot Vanheukelom, Nina Haenen, Talal Almahayni, Lieve Sweeck, Nancy Weyns, May Van Hees, Erik Smolders
Abstract. The transfer of radiocaesium (137Cs) from soil to crops is the main long-term radiation risk after nuclear accidents. The prevailing concept is that 137Cs sorption in soil, and hence its bioavailability, is controlled by soil clay content (0–2 µm). This study tested this assumption using 24 soils collected worldwide. The Radiocaesium Interception Potential (RIP), i.e., 137Cs adsorption, was

Missing the input: The underrepresentation of plant physiology in global soil carbon research Soil (IF 5.8) Pub Date : 2024-11-28 Sajjad Raza, Hannah V. Cooper, Nicholas T. Girkin, Matthew S. Kent, Malcolm J. Bennett, Sacha J. Mooney, Tino Colombi
Abstract. Plant processes regulating the quantity and quality of soil organic carbon inputs such as photosynthesis, above- and belowground plant growth, and root exudation are integral to our understanding of soil carbon dynamics. However, based on a bibliometric analysis including almost 50 000 scientific papers, we found that plant physiology has been severely underrepresented in global soil organic

Impact of crop type on the greenhouse gas (GHG) emissions of a rewetted cultivated peatland Soil (IF 5.8) Pub Date : 2024-11-27 Kristiina Lång, Henri Honkanen, Jaakko Heikkinen, Sanna Saarnio, Tuula Larmola, Hanna Kekkonen
Abstract. Raising the water table is an effective way to abate greenhouse gas emissions from cultivated peat soils. We experimented a gradual water table rise at a highly degraded agricultural peat soil site with plots of willow, forage and mixed vegetation (set-aside) in southern Finland. We measured the emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) for 4 years. The mean

Calcium is associated with specific soil organic carbon decomposition products Soil (IF 5.8) Pub Date : 2024-11-27 Mike C. Rowley, Jasquelin Pena, Matthew A. Marcus, Rachel Porras, Elaine Pegoraro, Cyrill Zosso, Nicholas O. E. Ofiti, Guido L. B. Wiesenberg, Michael W. I. Schmidt, Margaret S. Torn, Peter S. Nico
Abstract. Calcium (Ca) may contribute to the preservation of soil organic carbon (SOC) in more ecosystems than previously thought. Here we provide evidence that Ca is co-located with SOC compounds that are enriched in aromatic and phenolic groups, across different acidic soil-types and locations with different ecosystem properties. In turn, this co-localised fraction of Ca-SOC is removed through cation-exchange
