Microbial necromass carbon and nitrogen persistence are decoupled in agricultural grassland soils

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

Microbial Necromass in Soils—Linking Microbes to Soil Processes and Carbon Turnover [PDF]

Frontiers in Environmental Science, 2021
The organic matter of living plants is the precursor material of the organic matter stored in terrestrial soil ecosystems. Although a great deal of knowledge exists on the carbon turnover processes of plant material, some of the processes of soil organic

Plant detritus carbon dominates over microbial necromass carbon in topsoil of alpine ecosystems

Communications Earth & Environment
Determining microbial necromass carbon and plant detritus carbon is essential for accurate global soil organic carbon modeling. Yet soil organic carbon precursors are usually ignored in alpine assessments.

Environmental and microbial controls on microbial necromass recycling, an important precursor for soil carbon stabilization

Communications Earth & Environment, 2020
Microbial necromass recycling, which can influence soil carbon stabilization, is controlled by microbial growth and precipitation, as indicated by stable isotope tracing and indicator species analysis in a range of UK grasslands.

Microbial necromass carbon enhances arsenic methylation in paddy soils. [PDF]

Proc Natl Acad Sci U S A
Microbial necromass carbon (MNC) constitutes a critical component of soil organic carbon. Yet, how MNC regulates microbial arsenic (As) methylation processes in soil remains unclear. Across major Chinese rice-growing regions, bacterial and fungal necromass carbon showed significant positive correlations ( P

Light grazing promotes the accumulation of soil microbial necromass carbon in a desert steppe. [PDF]

BMC Plant Biol
Grazing, as one of the most important methods of utilizing natural grasslands, can significantly impact the accumulation and stabilization of soil organic carbon within grassland ecosystems. Soil microbial necromass carbon (MNC), including fungal necromass carbon (FNC) and bacterial necromass carbon (BNC), is an important source of soil organic carbon (

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.

Microbial physiology and necromass regulate agricultural soil carbon accumulation [PDF]

Soil Biology and Biochemistry, 2015
Abstract Strategies for mitigating soil organic carbon (SOC) losses in intensively managed agricultural systems typically draw from traditional concepts of soil organic matter formation, and thus emphasize increasing C inputs, especially from slowly decomposing crop residues, and reducing soil disturbance.

Decomposition of Microbial Necromass Is Divergent at the Individual Taxonomic Level in Soil

Frontiers in Microbiology, 2021
The turnover of microbial biomass plays an important part in providing a significant source of carbon (C) to soil organic C. However, whether the decomposition of microbial necromass (non-living microbial biomass) in the soil varies at the individual ...
