Shifts in controls and abundance of particulate and mineral-associated organic matter fractions among subfield yield stability zones Soil (IF 6.8) Pub Date : 2023-11-06 Sam J. Leuthold, Jocelyn M. Lavallee, Bruno Basso, William F. Brinton, M. Francesca Cotrufo
Abstract. Spatiotemporal yield heterogeneity presents a significant challenge to agricultural sustainability efforts and can strain the economic viability of farming operations. Increasing soil organic matter (SOM) has been associated with increased crop productivity, as well as the mitigation of yield variability across time and space. Observations at the regional scale have indicated decreases in

The effect of soil moisture content and soil texture on fast in situ pH measurements with two types of robust ion-selective electrodes Soil (IF 6.8) Pub Date : 2023-10-20 Sebastian Vogel, Katja Emmerich, Ingmar Schröter, Eric Bönecke, Wolfgang Schwanghart, Jörg Rühlmann, Eckart Kramer, Robin Gebbers
Abstract. In situ soil pH measurements with ion-selective electrodes (ISE) receive increasing attention in soil mapping for precision agriculture, as they can avoid time consuming sampling and off-site laboratory work. However, unlike the standard laboratory protocol, in situ pH measurements are carried out at lower and varying soil moisture content (SMC), which can have a pronounced effect on the

Using climate change scenarios to simulate mobility of metal contaminants in soils: the example of copper on a European scale Soil (IF 6.8) Pub Date : 2023-10-17 Laura Sereni, Julie-Mai Paris, Isabelle Lamy, Bertrand Guenet
Abstract. Soil contaminant deposition is highly dependent on anthropogenic activities while contaminant retention, mobility and availability are highly dependent on soil properties. The knowledge of partitioning between soil solid and solution phases is necessary to estimate whether deposited amounts of contaminants will rather be leached through runoff or accumulated. Besides pedological driven partitioning

The limited effect of deforestation on stabilized subsoil organic carbon in a subtropical catchment Soil (IF 6.8) Pub Date : 2023-10-16 Claude Raoul Müller, Johan Six, Liesa Brosens, Philipp Baumann, Jean Paolo Gomes Minella, Gerard Govers, Marijn Van de Broek
Abstract. Predicting the quantity of soil organic carbon (SOC) requires understanding about how different factors control the amount of SOC. Land use has a major influence on the function of the soil as a carbon sink, as shown by substantial organic carbon (OC) losses from the soil upon deforestation. Yet, predicting the degree to which land use change affects the SOC content, and the depth down to

Land inclination controls CO2 and N2O fluxes, but not CH4 uptake, in a temperate upland forest soil Soil (IF 6.8) Pub Date : 2023-09-19 Lauren M. Gillespie, Nathalie Y. Triches, Diego Abalos, Peter Finke, Sophie Zechmeister-Boltenstern, Stephan Glatzel, Eugenio Díaz-Pinés
Abstract. Inclination and spatial variability in soil and litter properties influence soil greenhouse gas (GHG) fluxes and thus ongoing climate change, but their relationship in forest ecosystems is poorly understood. To elucidate this, we explored the effect of inclination, distance from a stream, soil moisture, soil temperature, and other soil and litter properties on soil–atmosphere fluxes of carbon

Organic and inorganic nitrogen amendments reduce biodegradation of biodegradable plastic mulch films Soil (IF 6.8) Pub Date : 2023-09-15 Sreejata Bandopadhyay, Marie English, Marife B. Anunciado, Mallari Starrett, Jialin Hu, José E. Liquet y González, Douglas G. Hayes, Sean M. Schaeffer, Jennifer M. DeBruyn
Abstract. Biodegradable mulch films (BDMs) are a sustainable and promising alternative to non-biodegradable polyethylene mulches used in crop production systems. Nitrogen amendments in the form of fertilizers are used by growers to enhance soil and plant-available nutrients; however, there is limited research on how these additions impact the biodegradation of BDMs tilled into soils. A 4-month laboratory

Mineral Dust and Pedogenesis in the Alpine Critical Zone Soil (IF 6.8) Pub Date : 2023-09-13 Jeffrey S. Munroe, Abigail A. Santis, Elsa J. Soderstrom, Michael J. Tappa, Ann M. Bauer
Abstract. The influence of mineral dust deposition on soil formation in the mountain critical zone was evaluated at six sites in southwestern North America. Passive samplers collected dust for two years, and representative soil and rock were gathered in the vicinity of each dust sampler. All materials (dust, soil, and rock) were analysed to determine their mineralogy (with x-ray diffraction), geochemistry

Parent material influences soil abiotic N2O production from chemical oxidation of hydroxylamine Soil (IF 6.8) Pub Date : 2023-09-12 Suyun Li, Cai Gan, Danni Cai, Jiani Ma, Shurong Liu
Abstract. Hydroxylamine (NH2OH) and nitrite (NO2-) represent pivotal nitrification intermediates that substantially govern soil abiotic N2O production. Yet, the intricate factors influencing the abiotic formation of N2O from chemical reactions involving NH2OH and NO2- remain uncertain. This study was designed to reveal the impacts of land use type and parent material on soil abiotic N2O production
