Effects of Crop Rotation and Hydrogel Application on Soil Biological Properties and Wheat Biomass Production in Drylands

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim Conservation agriculture (CA) is rapidly gaining traction to promote sustainable crop production, focusing on minimum soil disturbance, permanent soil cover, and strategic crop rotation. Moreover, hydrogel is increasingly being used to improve water retention, including in combination with CA, particularly in water limited ...

Plant Availability of Phosphorus From Sewage Sludge Ash‐Based Fertilizers and Its Relationship to Phosphorus Extractability

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Sewage sludge ash (SSA) is a potential phosphorus (P) source for fertilizers, but untreated SSA (USSA) often shows low plant availability of P. To increase P availability, sodium additives can be applied before sewage sludge incineration or during thermochemical SSA posttreatment, as this leads to the formation of CaNaPO4.

Climate Change and Reduction of Soil Organic Layer Thickness Increases Drought Risk in Mountain Forests of the Northern Alps

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background On ca. 10% of the forested sites in the Bavarian Alps (Germany) mountain, forest soils (so‐called folic histosols) are characterized by thick organic layers overlying poorly weathered calcareous parent material. Aim These organic layers play a critical role in releasing water and nutrients for vegetation, yet they are also sensitive

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Review of the Salpausselkä ice‐marginal formations in Finland

Journal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...
