Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Microbial and Non‐Microbial Biostimulants for Soil Health in Managed Agricultural Systems: A Scientometric Analysis of Bioinputs From 2021 to 2025

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Biostimulants and related bioinputs encompass microbial and non‐microbial strategies used to improve plant performance, nutrient‐use efficiency, stress resilience, and soil functioning. Aim For this study, plant biostimulants were operationally defined as substances or microorganisms applied to enhance nutrient‐use efficiency ...

Low Soil Organic Matter Stability Exacerbates the Vulnerability of Karst Areas to Rocky Desertification

Land Degradation &Development, EarlyView.
ABSTRACT Karst rocky desertification represents a severe form of land degradation and has traditionally been attributed to geological and hydrological constraints. However, soil organic matter (SOM), a key regulator of erosion resistance, is highly responsive to management practices, yet its contribution to rocky desertification remains poorly ...

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

From Model to Practice: Testing Near‐Infrared Spectroscopy as a Bone Collagen Prescreening Tool

Archaeometry, EarlyView.
ABSTRACT Collagen is a vital archaeological material, preserving biochemical signatures that provide insights into past environments, diets, and human–animal interactions. However, diagenetic processes can lead to rapid and often inconspicuous degradation of collagen. Given the variability in collagen preservation and its significance for analyses such
