Plant diversity is key for microbial necromass carbon accrual in alpine grasslands

Communications Earth & Environment
The positive effect of plant diversity on soil carbon (C) stocks is well documented, yet its role in shaping persistent C components essential for long-term soil C stability remains unclear. Using a 3,000-km transect survey of natural grasslands, we found that both bacterial and fungal necromass C increased with plant species richness, with more ...

Ecosystem-level warming reduces microbial necromass in the topsoil but not in deeper soil of a subtropical forest

Geoderma
Rising temperatures in subtropical regions pose a significant challenge to soil carbon (C) storage. Microbial necromass is an important contributor to the persistent soil C pool, yet little is known about its responses to warming in subtropical forest ...

Six-year nitrogen addition alters microbial-derived carbon accumulation in association with soil stoichiometry and microbial community reorganization in an alpine coniferous forest

Frontiers in Forests and Global Change
BackgroundAtmospheric nitrogen (N) deposition can strongly alter soil organic carbon (SOC) stabilization by regulating microbial-derived carbon (C) formation.

Contrasting stability of fungal and bacterial communities during long-term decomposition of fungal necromass in Arctic tundra

Environmental Microbiome
Decomposition is a crucial process in terrestrial ecosystems, driving nutrient cycling and carbon storage dynamics. Considering the amount of fungal necromass produced in soils annually, its decomposition represents an important nutrient recycling ...

Arbuscular mycorrhizal fungi communities and glomalin mediate particulate and mineral-associated organic carbon formation in grassland patches

Communications Earth & Environment
Arbuscular mycorrhizal fungi stimulate particulate and mineral-associated organic carbon formation and stabilization through hyphae residue, glomalin-related soil proteins gluing, and mycelium entangling.

Legume cover crops sequester more soil organic carbon than non-legume cover crops by stimulating microbial transformations

Geoderma
Cover crops are one of the climate-smart agricultural practices used to increase soil organic carbon (SOC) sequestration. However, the SOC sequestration potential and underlying mechanisms under different cover crops, especially in orchard agroecosystems,

Changes in plant lignin components and microbial necromass matter with subtropical forest restoration

Geoderma
Soil organic carbon (SOC) represents the largest carbon reservoir in terrestrial ecosystems. Therefore, understanding how to enhance SOC is crucial for the global carbon cycle and atmospheric CO2 removal. While there has been reported on SOC accumulation

Microbial necromass carbon dominates the accumulation of soil organic carbon in bedrock-exposed areas of karst regions

Geoderma
Bedrock exposure alters the stability of soil organic carbon (SOC) in karst ecosystems; however, the responses of plant- and microbial-derived carbon—key indicators for assessing SOC stability—to bedrock exposure rates remain unclear. To address this, we

Biochar amendment reduced microbial necromass carbon accumulation in a paddy soil profile

Journal of Integrative Agriculture
Microbial necromass carbon (MNC) serves a crucial function in the formation and stabilization of soil organic carbon (SOC). Although biochar amendment is recognized as a promising approach for enhancing SOC sequestration, its impact on MNC accumulation ...
