Earthworms as catalysts in the formation and stabilization of soil microbial necromass [PDF]
Global Change Biology, 2022 AbstractMicrobial necromass is a central component of soil organic matter (SOM), whose management may be essential in mitigating atmospheric CO2 concentrations and climate change. Current consensus regards the magnitude of microbial necromass production to be heavily dependent on the carbon use efficiency of microorganisms, which is strongly influenced

Root Exudates Shape Soil Organic Carbon Stabilization by Controlling Microbial Necromass Formation Under Long-Term Nitrogen Fertilization [PDF]
MicroorganismsSoil organic carbon (SOC) stabilization is largely governed by the accumulation of microbial necromass carbon, yet how stabilization is influenced by root exudation remains poorly understood, particularly under long-term nitrogen (N) fertilization. Here,

Sticky dead microbes: Rapid abiotic retention of microbial necromass in soil [PDF]
Soil Biology and Biochemistry, 2020 Abstract Microbial necromass dominates soil organic matter. Recent research on necromass and soil carbon storage has focused on necromass production and stabilization mechanisms but not on the mechanisms of necromass retention. We present evidence from soil incubations with stable-isotope labeled necromass that abiotic adsorption may be more ...

Fertilization and Aridity Legacies Determine Soil Microbial Necromass Persistence Across Climates [PDF]
Global Change BiologyABSTRACT Microbial necromass‐mineral interactions are vital for soil organic carbon (C) persistence, but their response to concurrent climate and fertilization legacies in croplands remains unclear. Using six long‐term field sites (27–38 years) across a pronounced aridity gradient, we show that stabilization of microbial necromass is ...

Microbial Necromass, Lignin, and Glycoproteins for Determining and Optimizing Blue Carbon Formation
Environmental Science & Technology, 2023 Coastal wetlands contribute to the mitigation of climate change through the sequestration of "blue carbon". Microbial necromass, lignin, and glycoproteins (i.e., glomalin-related soil proteins (GRSP)), as important components of soil organic carbon (SOC), are sensitive to environmental change.

The divergent accumulation mechanisms of microbial necromass C in paddy soil under different long-term fertilization regimes [PDF]
Geoderma, 2023 To investigate the stabilization mechanism of microbial necromass carbon (C) in rice paddy soil, the accumulation of microbial necromass and its contribution to SOC in bulk soil and in various fractions were addressed under a 40-year fertilization trial.

Ecosystem‐Dependent Responses of Microbial Necromass Carbon to Warming Are Governed by the Balance Between Necromass Formation and Decomposition [PDF]
Glob Chang BiolMicrobial necromass carbon (MNC) is increasingly recognized as a major contributor to persistent soil organic carbon (SOC), yet its response to climate warming and the underlying regulatory mechanisms remain poorly understood. Here, we conducted a global

Defining a core microbial necrobiome associated with decomposing fungal necromass
FEMS Microbiology Ecology, 2023 Abstract Despite growing interest in fungal necromass decomposition due to its importance in soil carbon retention, whether a consistent group of microorganisms is associated with decomposing necromass remains unresolved. Here, we synthesize knowledge on the composition of the bacterial and fungal communities present on decomposing ...

Responses of microbial necromass carbon and microbial community structure to straw- and straw-derived biochar in brown earth soil of Northeast China [PDF]
Frontiers in Microbiology, 2022 Soil microbial organisms are conducive to SOC sequestration. However, little attention has been given to the contributions of living MBC and microbial necromass carbon to the SOC pool under biochar and straw amendments.

Microbial necromass carbon and nitrogen persistence are decoupled in agricultural grassland soils [PDF]
Communications Earth & Environment, 2022 Different mineralization rates between plant litter and microbial necromass do not necessarily imply differences in carbon persistence, and necromass carbon is less persistent than nitrogen, according to inoculation experiments with grassland soils under
