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

BMC Plant Biology
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 (

Key role of microbial necromass and iron minerals in retaining micronutrients and facilitating biological nitrogen fixation in paddy soils [PDF]

Fundamental Research
Paddy fields, as the largest anthropogenic wetlands on Earth, face a high risk of micronutrient loss through surface runoff and leaching due to their frequent irrigation-drainage cycles, as well as removal with crop harvest.

Bacterial functional traits: a key driver of soil organic carbon dynamics during reductive soil disinfestation [PDF]

Frontiers in Microbiology
Reductive soil disinfestation (RSD) significantly enhanced SOC content. However, its microbial mechanisms mediated through changes in microbial necromass carbon, particularly under different organic amendments, remain poorly understood.

Rapid evolution in necromass use under resource limitation reduces persistence in producer-decomposer microbial biospheres [PDF]

Communications Biology
Decomposer bacteria recycle necromass, the organic remnants of dead cells. This process underlies ecological system persistence via provisioning matter for future generations; however, it is unknown if more efficient necromass recycling also improves the

Manufacturing triple-isotopically labeled microbial necromass to track C, N and P cycles in terrestrial ecosystems [PDF]

, 2022
The functional relevance of microbial necromass in terrestrial biogeochemical cycles remains one of the unresolved mysteries of element cycling in ecosystems, especially considering the high microbial abundance and turnover in soil.

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.

Initial soil formation by biocrusts: Nitrogen demand and clay protection control microbial necromass accrual and recycling

, 2022
Microbial biomass is increasingly considered to be the main source of organic carbon (C) sequestration in soils. Quantitative information on the contribution of microbial necromass to soil organic carbon (SOC) formation and the factors driving necromass ...

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 ...
