Limited evidence for soil enzyme activities mediating C:N discrepancies between microbial biomass and organic matter in year 145 of a maize‐based agroecosystem experiment

Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Soil microbial biomass (MB) generally exhibits a narrower C:N than soil organic matter (SOM), creating a stoichiometric discrepancy hypothesized to be reconciled in part by C‐ and N‐acquiring enzyme activities. We used soils from an at‐equilibrium long‐term experiment to evaluate the degree to which MB C:N plasticity and enzyme activities ...

Microbial Necromass and Extracellular Enzyme Activities Are Associated with Depth-Dependent Soil Carbon Stabilization Along a Wildfire-Severity Gradient

Microorganisms
Wildfire can alter soil organic carbon (SOC) pools and microbial pathways of carbon stabilization, but depth-dependent links between microbial necromass and stable carbon pools remain unclear. We investigated a wildfire-severity gradient in a subtropical

Assessing fungal–mineral interactions in soil: A review of microscale methods

Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Biological weathering of minerals has profoundly transformed Earth over geologic time by driving soil formation, nutrient cycling, and long‐term biogeochemical processes. Among soil biota, fungi are increasingly recognized as key yet obscure drivers of weathering through their unique hyphal growth forms, metabolic capabilities, and symbiotic ...

Contrasting stability of fungal and bacterial communities during long-term decomposition of fungal necromass in Arctic tundra

Environmental Microbiome
Decomposition is a crucial process in terrestrial ecosystems, driving nutrient cycling and carbon storage dynamics. Considering the amount of fungal necromass produced in soils annually, its decomposition represents an important nutrient recycling ...

Contrasting Freeze–Thaw Regimes and Straw Amendment Reshape Microbial Necromass and Soil Carbon Pools in Saline–Alkali Paddy and Maize Soils

Agronomy
Soil carbon dynamics in seasonal freeze–thaw zones reflect the interplay of two temporal regimes: high-frequency symmetric cycles driven by diurnal temperature fluctuations, and low-frequency asymmetric cycles with extended freezing and brief thawing ...

Decades of High Nitrogen Deposition Mainly Enhanced Eutrophication Rather Than Acidification of Dutch Forest Soils

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract In the last decades, forest in the Netherlands have been exposed to high levels nitrogen (N) deposition, which allows to assess the fate and impacts of N and evaluate the concept of N saturation in this large scale “experiment” and related soil acidification.

Changes in plant lignin components and microbial necromass matter with subtropical forest restoration

Geoderma
Soil organic carbon (SOC) represents the largest carbon reservoir in terrestrial ecosystems. Therefore, understanding how to enhance SOC is crucial for the global carbon cycle and atmospheric CO2 removal. While there has been reported on SOC accumulation

Long‐Term Impact of Cropping System and Nitrogen Input Quality on Nitrogen Release and Organic Matter Chemistry

European Journal of Soil Science, Volume 77, Issue 5, September–October 2026.
ABSTRACT Long‐term integrated soil management strategies are essential for enhancing soil organic matter (SOM) quality and promoting the availability of mineralizable nitrogen (N). This study employed a tripartite analytical framework to investigate how crop rotations and organic N amendments influence soil N availability and SOM chemistry.

Macroaggregate disintegration mediates forest gap impacts on MAOC decrease in karst ecosystems

Geoderma
Forest gap disturbances, which are projected to intensify with climate change, threaten the stability of mineral-associated organic carbon (MAOC) in karst soils.
