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 ...

Microbial necromass in cropland soils: A global meta‐analysis of management effects

Global Change Biology, 2023
AbstractMicrobial necromass is a large and persistent component of soil organic carbon (SOC), especially under croplands. The effects of cropland management on microbial necromass accumulation and its contribution to SOC have been measured in individual studies but have not yet been summarized on the global scale.

Microbial necromass as the source of soil organic carbon in global ecosystems

Soil Biology and Biochemistry, 2021
Abstract Despite the recognized importance of the contribution of microbial necromass to soil organic carbon (SOC) sequestration, at a global scale, there has been no quantification for cropland, grassland, and forest ecosystems. To address this knowledge gap, the contents of fungal and bacterial necromass were estimated based on glucosamine and ...

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

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.

Deconstructing the microbial necromass continuum to inform soil carbon sequestration [PDF]

Functional Ecology, 2022
Abstract Microbial necromass is a large, dynamic and persistent component of soil organic carbon, the dominant terrestrial carbon pool. Quantification of necromass carbon stocks and its susceptibility to global change is becoming standard practice in soil carbon research.

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 ...

Sowing crop affects soil microbial necromass carbon via altering soil fungal community structure in a macadamia-based agroforestry system

Ecological Indicators, 2023
Agroforestry management practices governed soil organic carbon (SOC) and microbial community structure in terrestrial ecosystems, yet the effect of these practices on microbial necromass carbon (C) remain poorly understood in a subtropical region.
