Cadmium in topsoils of the European Union - An analysis based on LUCAS topsoil database.

open access: yesScience of the Total Environment, 2023
Cadmium (Cd) is a naturally occurring element that can accumulate in the soil through the application of fertilisers containing cadmium and as a waste of industrial processes.

Spatial assessment of topsoil zinc concentrations in Europe.

open access: yesScience of the Total Environment, 2023
Zinc (Zn) is essential to sustain crop production and human health, while it can be toxic when present in excess. In this manuscript, we applied a machine learning model on 21,682 soil samples from the Land Use and Coverage Area frame Survey (LUCAS ...

Drought reduces water uptake in beech from the drying topsoil, but no compensatory uptake occurs from deeper soil layers

open access: yesNew Phytologist, 2021
Summary The intensity and frequency of droughts events are projected to increase in future with expected adverse effects for forests. Thus, information on the dynamics of tree water uptake from different soil layers during and after drought is crucial ...

A spatial assessment of mercury content in the European Union topsoil

open access: yesScience of the Total Environment, 2021
Mapping of surface soil Hg concentrations, a priority pollutant, at continental scale is important in order to identify hotspots of soil Hg distribution (e.g. mining or industrial pollution) and identify factors that influence soil Hg concentrations (e.g.

Global biogeography of fungal and bacterial biomass carbon in topsoil

open access: yesSoil Biology and Biochemistry, 2020
Bacteria and fungi, representing two major soil microorganism groups, play an important role in global nutrient biogeochemistry. Biogeographic patterns of bacterial and fungal biomass are of fundamental importance for mechanistically understanding ...

Macro- and microscale gaseous diffusion in a Stagnic Luvisol as affected by compaction and reduced tillage [PDF]

open access: yes, 2008
Intensification of mechanical agriculture has increased the risk for soil compaction and deformation. Simultaneously, reduced tillage practices have become popular due to energy saving and environmental concerns, as they may strengthen and improve the ...

Phase Composition of Urban Soils by X-Ray Diffraction and Mössbauer Spectroscopy Analysis [PDF]

open access: yesArchives of Metallurgy and Materials, 2019
The main purpose of this study was to identify the mineral composition of soil sample taken from the upper layer of topsoil. High absorption of chemical substance is a characteristic for humus-organic layer of topsoil. The source of those substance could

Carbon mineralization and microbial activity in agricultural topsoil and subsoil as regulated by root nitrogen and recalcitrant carbon concentrations [PDF]

open access: yes, 2018
Aims Mechanisms of subsoil carbon sequestration from deep-rooted plants are elusive, but may contribute to climate change mitigation. This study addressed the role of root chemistry on carbon mineralization and microbiology in a temperate agricultural ...

Modeling the phosphorus balance of different soilsusing the 4M crop model

open access: yesPlant, Soil and Environment, 2012
Our study focuses on the phosphorus (P) balance in two long-term fertilization experiments which were carried out in characteristic soils of Hungary with four fertilization treatments and four main crops. The objectives of this study are: (1) to quantify
