Afforestation increased the microbial necromass carbon accumulation in deep soil on the Loess Plateau

Journal of Environmental Management
Microbial necromass carbon (MNC) is a stable part of SOC that makes up most of the C pool in land ecosystem. However, the contribution of MNC to SOC accumulation during afforestation is still unclear, particularly in the deep soil. Based on the collection and biomarker analysis of the forest succession sequence and soil profiles with significant depth ...

Global synthesis on the response of soil microbial necromass carbon to climate‐smart agriculture

Global Change Biology
AbstractClimate‐smart agriculture (CSA) supports the sustainability of crop production and food security, and benefiting soil carbon storage. Despite the critical importance of microorganisms in the carbon cycle, systematic investigations on the influence of CSA on soil microbial necromass carbon and its driving factors are still limited.

Microbial traits are shaped by soil type with potential implications for microbial necromass carbon cycling

Microbial necromass carbon (MNC) is 15-80% of SOC and is controlled by necromass production (microbial growth and death), stabilisation (minerals and aggregates), and consumption (recycling and destabilisation). Microbial traits (i.e., quantitative measures that capture differences in life strategies or niche segregation among taxa) provide a step ...

Microbial life-history strategies and particulate organic carbon mediate formation of microbial necromass carbon and stabilization in response to biochar addition

Science of the Total Environment
Microbial necromass carbon (MNC) contributes significantly to the formation of soil organic carbon (SOC). However, the microbial carbon sequestration effect of biochar is often underestimated and influenced by nutrient availability. The mechanisms associated with the formation and stabilization of MNC remain unclear, especially under the combined ...

Vegetation and microtopography drive microbial necromass carbon sequestration in wetland soils

Floodplain wetlands are important carbon sinks, yet drought-induced water level declines threaten this function by triggering mudflat-to-meadow transitions that alter soil organic carbon (SOC) stocks and stability. Microtopography shapes wetland hydrology and vegetation productivity; however, its interactive effects with vegetation on microbial ...

Microbial Community Traits and Necromass Dynamics Shape Soil Carbon Accumulation

Global Change Biology
ABSTRACT Soil organic carbon (SOC) sequestration is vital for food security and climate mitigation. However, its long‐term response to fertilisation remains unclear. Using the 180‐year Broadbalk Experiment (the world's longest‐running fertilisation trial; Rothamsted, UK), combined with 14

The Convertion of Croplands to Wetlands Alters Soil Organic Carbon by Regulating Soil Particulate and Microbial Necromass Carbon

Journal of Environmental Management
Natural wetlands store 20-30 % of soil organic carbon (SOC), and conversion of croplands to wetlands is thus an effective strategy for SOC restoration. However, the contribution of microbial necromass carbon to SOC change during this conversion process remains unclear.

Salinity decreases the contribution of microbial necromass to soil organic carbon pool in arid regions

Science of The Total Environment
Saline soils are widely distributed in arid areas but there is a lack of mechanistic understanding on the effect of salinity on the formation and biochemical composition of soil organic carbon (SOC). We investigated the effects of salinity on the accumulation of microbial necromass under natural vegetation and in cropland in salt-affected arid areas ...

Microbial necromass carbon contributed to soil organic carbon accumulation and stabilization in the newly formed inland wetlands

Environmental Research
Inland wetlands might be an important "carbon sink", and the chronosequence development of newly formed inland wetlands offers a natural and suitable opportunity for studying the dynamic effect of plant and microbial necromass carbon (PlantC and MNC) on the soil organic carbon (SOC) stabilization. The space-for-time chronosequence approach was used and

Effects of vegetation restoration on soil microbial necromass carbon and organic carbon in grazed and degraded sandy land

Journal of Environmental Management
Vegetation restoration effectively enhances carbon (C) sequestration and supports the sustainable management of degraded ecosystems. However, its impact on the accumulation of microbial necromass C (NC) and soil organic C (SOC) in degraded and grazed sandy land remains unclear.
