ABSTRACT Soil compaction poses a significant threat to soil quality and sustainability, necessitating advanced assessment methods. We hypothesized that incorporating x‐ray computed tomography (XCT)‐derived pore characteristics with hydraulic properties would significantly enhance the development of a soil quality index (SQI) under soil compaction ...

ABSTRACT Sustaining soil potassium (K) supply in intensive continuous cropping systems is increasingly challenging because long‐term crop removal often exceeds the natural replenishment capacity of soil K‐bearing minerals, leading to progressive depletion of plant‐available K pools.

New experimental method for loess collapsibility using centrifugal model tests
The methods for loess collapsibility mainly include field immersion testing method and laboratory testing method. A majority of the results of laboratory testing method differ greatly from the engineering practice.

ABSTRACT Subalpine meadows play important roles in biodiversity conservation and soil carbon sequestration, but gully erosion poses a serious threat to their ecological stability. Soil shear strength (τ) is a key mechanical parameter for evaluating gully stability and soil resistance to failure. However, the spatial variation in soil shear strength and

A review of preferential flow and transport through root channels
Abstract Preferential flow can contribute up to 80%–90% of the flow and transport in the vadose zone. The root channels are the most prevalent form of preferential pathways. They create an evolving network of preferential pathways and are biogeochemical hotspots due to preferential transport of nutrients and other organics, colonization of bacteria ...

Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.

ABSTRACT Background We examined patient and visit trends in pediatric emergency department (ED) usage during the school year and summer breaks before, during, and after the COVID‐19 pandemic. Methods We extracted data on mental health‐related visits to the ED of an academic medical center from 2018 to 2023 among youth aged 5–18.

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Unravelling upbuilding pedogenesis in tephra and loess sequences in New Zealand using tephrochronology [PDF]
The genesis of soils developed in either tephra or loess on stable sites differs markedly from that of soils developed on rock because classical topdown processes operate in conjuction with geological processes whereby material is added to the land ...
