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.

The divergent accumulation mechanisms of microbial necromass C in paddy soil under different long-term fertilization regimes

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.

Global microbial necromass contribution to soil organic matter [PDF]

, 2021
Abstract Soil organic matter (SOM) plays an important role in mitigating climate change and sustaining soil health and food production 1,2. Mounting evidence suggests that microbial necromass is the main contributor to SOM 3; however, we lack quantification of microbial necromass at a global scale, especially in subsoils. Here, we generate, for

Melanization slows the rapid movement of fungal necromass carbon and nitrogen into both bacterial and fungal decomposer communities and soils

mSystems, 2023
Microbial necromass contributes significantly to both soil carbon (C) persistence and ecosystem nitrogen (N) availability, but quantitative estimates of C and N movement from necromass into soils and decomposer communities are lacking.

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 ...

Increased microbial sequestration of soil organic carbon under nitrogen deposition over China’s terrestrial ecosystems

Ecological Processes, 2020
Background China’s terrestrial ecosystems have been receiving increasing amounts of reactive nitrogen (N) over recent decades. External N inputs profoundly change microbially mediated soil carbon (C) dynamics, but how elevated N affects the soil organic ...

Quantitative assessment of microbial necromass contribution to soil organic matter [PDF]

Global Change Biology, 2019
AbstractSoil carbon transformation and sequestration have received significant interest in recent years due to a growing need for quantitating its role in mitigating climate change. Even though our understanding of the nature of soil organic matter has recently been substantially revised, fundamental uncertainty remains about the quantitative ...

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.

Microbial necromass under global change and implications for soil organic matter

Global Change Biology, 2023
AbstractMicrobial necromass is an important source and component of soil organic matter (SOM), especially within the most stable pools. Global change factors such as anthropogenic nitrogen (N), phosphorus (P), and potassium (K) inputs, climate warming, elevated atmospheric carbon dioxide (eCO2), and periodic precipitation reduction (drought) strongly ...

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

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
