Plant litter decomposition is regulated by its phosphorus content in the short term and soil enzymes in the long term

Geoderma
Plant litter decomposition plays a vital role in soil carbon (C) cycling and nutrient release, significantly influencing agricultural resource utilization and soil fertility management.

Disentangling direct and indirect effects of water table drawdown on above and belowground plant litter decomposition: Consequences for accumulation of organic matter in boreal peatlands. [PDF]

, 2011
Pristine peatlands are carbon (C) accumulating wetland ecosystems sustained by a high water table (WT) and consequent anoxia that slows down decomposition.

Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

Land Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

Leaf litter decomposition rates increase with rising mean annual temperature in Hawaiian tropical montane wet forests [PDF]

, 2014
Decomposing litter in forest ecosystems supplies nutrients to plants, carbon to heterotrophic soil microorganisms and is a large source of CO2 to the atmosphere.

Impact of Nitrogen Deposition on Carbon and Nitrogen Cycling in Peatlands Under Land‐Use Change

Land Degradation &Development, EarlyView.
ABSTRACT Increasing nitrogen (N) deposition significantly alters carbon and N dynamics in peatlands by affecting microbial processes, enhancing greenhouse gas emissions and nutrient leaching into adjacent waters. However, how peatland conversion for agriculture and forestry influences the fate of added N under elevated atmospheric deposition remains ...

Bacterial Diversity in Agricultural Soils during Litter Decomposition [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT Denaturing gradient gel electrophoresis (DGGE) of amplified fragments of genes coding for 16S rRNA was used to study the development of bacterial communities during decomposition of crop residues in agricultural soils. Ten strains were tested, and eight of these strains produced a single band.

Underground Lag: Fungal Community and Edaphic Legacies After Disturbance

Land Degradation &Development, EarlyView.
ABSTRACT Páramos are neotropical mountain ecosystems that regulate water and store large amounts of carbon, but are increasingly degraded by agriculture and grazing. Although native vegetation often recolonizes after abandonment, belowground recovery remains poorly understood.

Macrophyte litter mixtures mediate decomposition processes in coastal sediments

Communications Earth & Environment
Understanding litter decomposition processes in coastal macrophyte habitats is critically important for predicting ecosystem functioning. However, decomposition processes of litter mixtures in coastal habitats remain largely unexplored.

Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...
