The vertical distribution and control of microbial necromass carbon in forest soils

Global Ecology and Biogeography, 2020
AbstractAimForest soils contain large amounts of terrestrial organic carbon (C), but the formation pathway of soil organic C (SOC) remains unclear. Recent evidence suggests that microbial necromass is a significant source of SOC, yet a global quantitative assessment across the whole soil profile is lacking.

Large‐scale importance of microbial carbon use efficiency and necromass to soil organic carbon

Global Change Biology, 2021
AbstractOptimal methods for incorporating soil microbial mechanisms of carbon (C) cycling into Earth system models (ESMs) are still under debate. Specifically, whether soil microbial physiology parameters and residual materials are important to soil organic C (SOC) content is still unclear. Here, we explored the effects of biotic and abiotic factors on

Microbial necromass ≠ microbial biomass: Microbial death pathways affect soil organic carbon sequestration

2023
The last two decades soil organic matter research developed rapidly, uncovering a central role of soil microorganisms in the sequestration and storage of soil organic carbon (C), especially through accumulation of their necromass. However, despite strong evidence that the so-called soil microbial carbon pump is an important process, the direct ...

Patterns and controlling factors of soil microbial necromass carbon in global ecosystems

Journal of Environmental Management
Microbial necromass is a critical source of soil organic carbon (SOC) in terrestrial ecosystems, and the quantity and quality of microbial necromass carbon (MNC) can influence long-term soil carbon sequestration. However, few studies have explored the distribution of soil MNC and its contribution to SOC along the soil profiles across different ...

Rhizosphere as a hotspot for microbial necromass deposition into the soil carbon pool

Journal of Ecology
Abstract Microbial leftovers, known as necromass, are key players in storing carbon in the soil around plant roots (i.e. rhizosphere), a zone characterized by high‐efficiency microbial anabolism.

Depth‐dependent drivers of soil microbial necromass carbon across Tibetan alpine grasslands

Global Change Biology, 2021
AbstractMicrobial necromass carbon (C) has been considered an important contributor to persistent soil C pool. However, there still lacks large‐scale systematic observations on microbial necromass C in different soil layers, particularly for alpine ecosystems.

Necromass responses to warming: A faster microbial turnover in favor of soil carbon stabilisation

Science of the Total Environment
Microbial byproducts and residues (hereafter 'necromass') potentially play the most critical role in soil organic carbon (SOC) sequestration. However, little is known about the influence of climate warming on necromass accumulation in the agroecosystem and the underlying mechanisms associated with microbial life strategies.

Spatial variation and controls of soil microbial necromass carbon in a tropical montane rainforest

Science of the Total Environment
Soil microbial necromass carbon is an important component of the soil organic carbon (SOC) pool which helps to improve soil fertility and texture. However, the spatial pattern and variation mechanisms of fungal- and bacterial-derived necromass carbon at local scales in tropical rainforests are uncertain.

Microbial necromass carbon in estuarine tidal wetlands of China: Influencing factors and environmental implication

Science of the Total Environment, 2023
Microbial necromass is an important component of the stable soil organic carbon (SOC) pool. However, little is known about the spatial and seasonal patterns of soil microbial necromass and their influencing environmental factors in estuarine tidal wetlands.

Microbial necromass contribution to soil carbon storage via community assembly processes

Science of The Total Environment
Soil organic matter has been well acknowledged as a natural solution to mitigate climate change and to maintain agricultural productivity. Microbial necromass is an important contributor to soil organic carbon (SOC) storage, and serves as a resource pool for microbial utilization.
