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

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 ...

Divergent accumulation of microbial necromass and plant lignin components in grassland soils [PDF]

Nature Communications, 2018
It remains unclear how microbes and plants contribute to soil organic carbon (SOC) accrual. Here, using biomarkers, the authors show that microbial necromass and plant-derived lignin components have divergent accumulation mechanisms and that microbial ...

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

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.

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 response to soil warming: A meta-analysis

Frontiers in Soil Science, 2022
Microbial-derived soil organic matter (SOM), or necromass, is an important source of SOM and is sensitive to climate warming. Soil classification systems consider soil physicochemical properties that influence SOM, hinting at the potential utility of ...

Clay-organic matter interactions drive microbial necromass preservation in soils [PDF]

Nature Communications
Microbial necromass is increasingly recognized as a major source of stable soil organic matter (SOM), and its persistence is often attributed to interactions with clay-sized minerals. However, the mechanisms underlying this mineral-mediated stabilization

Earthworms as catalysts in the formation and stabilization of soil microbial necromass. [PDF]

Glob Chang Biol, 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

Afforestation of severely desertified land in semi-arid areas promotes soil carbon and nitrogen accumulation through microbial necromass [PDF]

Communications Biology
Afforestation is an important measure used to expand carbon (C) sequestration and mitigate climate change. However, the impact of soil microbial necromass on soil C and nitrogen (N) sequestration still remain unclear following afforestation of severely ...

Sticky Dead Microbes: rapid abiotic retention of microbial necromass in soil [PDF]

Soil Biology and Biochemistry, 2020
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.

Distinct Roles of Plant Residues and Microbial Necromass in Soil Organic Carbon Accumulation and Stability in the Alhagi sparsifolia Community [PDF]

Plants
In desert ecosystems, deep-rooted plants like Alhagi sparsifolia contribute not only to wind prevention and sand fixation but also to the transport of carbon into deep soil layers through their root systems.
