Contribution of microbial activity and vegetation cover to the spatial distribution of soil respiration in mountains

Frontiers in Microbiology, 2023
The patterns of change in bioclimatic conditions determine the vegetation cover and soil properties along the altitudinal gradient. Together, these factors control the spatial variability of soil respiration (RS) in mountainous areas.

Comparison of the Sorption of Cu(II) and Pb(II) by Bleached and Activated Biochars: Insight into Complexation and Cation–π Interaction

Agronomy, 2023
Attention has been paid to the application of biochar in the remediation of heavy metal contamination in soils. In this study, two modification methods, bleaching and activation, were used to enhance the biochar sorption of Cu(II) and Pb(II).

Biochar Extracts Can Modulate the Toxicity of Persistent Free Radicals in the Nematode Caenorhabditis elegans

Applied Biosciences, 2023
As an effective soil amendment, biochars require a comprehensive ecological evaluation before they can be widely used in agriculture because endogenous contaminants, such as environmentally persistent free radicals (EPFRs), certainly pose an ecological ...

Large errors in soil carbon measurements attributed to inconsistent sample processing [PDF]

SOIL
To build confidence in the efficacy of soil carbon (C) crediting programs, precise quantification of soil organic carbon (SOC) is critical. Detecting a true change in SOC after a management shift has occurred, specifically in agricultural lands, is ...

Inhibited vertical mobility of biochar-derived dissolved organic matter under low-intensity rainfall: role of mineral retention

Biochar
Biochar has great potential in the application areas of carbon sequestration and environmental remediation. A significant amount of dissolved organic matter (DOM) may be released from biochar, which is highly reactive and mobile.
