Drivers of microbially and plant‐derived carbon in topsoil and subsoil

Global Change Biology, 2023
Plant‐ and microbially derived carbon (C) are the two major sources of soil organic matter (SOM), and their ratio impacts SOM composition, accumulation, stability, and turnover.

Wheat cultivars with small root length density in the topsoil increased post-anthesis water use and grain yield in the semi-arid region on the Loess Plateau

European Journal of Agronomy, 2021
Large distribution of roots in topsoil layers allow more uptake of soil water and nutrients during the vegetative growth, but it may be disadvantageous if soil water deficit develops during the reproductive stage.

Fungal necromass is reduced by intensive drought in subsoil but not in topsoil

Global Change Biology, 2023
The frequency and intensity of droughts worldwide are challenging the conservation of soil organic carbon (SOC) pool. Microbial necromass is a key component of SOC, but how it responds to drought at specific soil depths remains largely unknown.

Global predictions of topsoil organic carbon stocks under changing climate in the 21st century.

Science of the Total Environment, 2023
The organic carbon (OC) stored in global topsoil (0-30 cm) will be the most active participant in the carbon cycle under future climate change. Due to differences in focus regions or research methods, the spatio-temporal changes of future global topsoil ...

Soil acidification and factors controlling topsoil pH shift of cropland in central China from 2008 to 2018

Geoderma, 2022
Soil acidification can negatively impact the sustainability of agricultural systems. Spatially explicit estimations of soil acidification and the identification of local factors driving soil pH change are prerequisites for formulating and implementing ...

Digital mapping of zinc in urban topsoil using multisource geospatial data and random forest.

Science of the Total Environment, 2021
This study aimed to map the spatial patterns of Zn in urban topsoil by using multisource geospatial data and machine learning method. Geological map, digital elevation models, and Landsat images were used to extract data related to geology, relief, and ...

Long-term impacts of topsoil depth and amendments on soil physical and hydrological properties of an Alfisol in central Ohio, USA

, 2020
Soil hydrological properties and aggregate stability are strongly impacted by erosion and management practices. However, magnitudes of the erosion-induced changes in topsoil depth and the attendant alterations in soil properties are not well understood ...
