Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,

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 ...
