Lability of organic carbon in lakes of different trophic status
Freshwater Biology, 2009Summary1. We used first‐order kinetic parameters of biological oxygen demand (BOD), the constant of aerobic decomposition (k) and the asymptotic value of BOD (BODult), to characterise the lability of organic carbon pools in six lakes of different trophic state: L. Naroch, L. Miastro and L. Batorino (Belarus), L. Kinneret (Israel), L.

Soil Research, 2006
Forty-four soils from under native vegetation and a range of management practices following clearing were analysed for ‘labile’ organic carbon (OC) using both the particulate organic carbon (POC) and the 333 mm KmnO4 (MnoxC) methods. Although there was some correlation between the 2 methods, the POC method was more sensitive by about a factor of 2 to ...

A distinct sensitivity to the priming effect between labile and stable soil organic carbon
New Phytologist, 2022Summary Soil organic carbon (SOC) is a mixture of various carbon (C) compounds with different stability, which can be distinctly affected by the priming effect (PE). However, little is known about how the PE changes with SOC stability. We address this issue by combining results from two experiments and a metaanalysis. We found that the PE increased

Lability of soil organic carbon in tropical soils with different clay minerals
Soil Biology and Biochemistry, 2010Abstract Soil organic carbon (SOC) storage and turnover is influenced by interactions between organic matter and the mineral soil fraction. However, the influence of clay content and type on SOC turnover rates remains unclear, particularly in tropical soils under natural vegetation.

Simulating decomposition of labile soil organic carbon: Effects of pH
Soil Biology and Biochemistry, 2008Based on previous studies we suppose common soil carbon turnover modelling approaches to fail to accurately simulate the fate of labile organic carbon in acidic soils possibly because pH effects on decomposition are not accounted for. For mountainous permanent grasslands with higher shares of particulate carbon, turnover times of this fraction were ...

A novel molecular approach based on carbon‐normalized yields of combined amino acids was developed to quantify concentrations of labile (L), semi‐labile (S), and refractory (R) dissolved organic carbon (DOC) in shelf and basin waters of the Western Arctic Ocean. Concentrations of L‐DOC were seasonally and spatially variable (0.1‐14.2 µmol L−1).

Labile and Stable Soil Organic Carbon in abandoned lands with different management
2023Soil is a key element in the Earth system, and changes in land management can affect soil organic carbon (SOC) dynamics and the provision of ecosystem services related to soil. The content and stock of SOC has been adopted as the measure to be used for land degradation assessment.

AbstractSoil organic matter (SOM) mineralization processes are central to the functioning of soils in relation to feedbacks with atmospheric CO2 concentration, to sustainable nutrient supply, to structural stability and in supporting biodiversity. Recognition that labile C‐inputs to soil (e.g.

Ecosystems, 2009
The large pool of actively cycling carbon (C) held in soils is susceptible to release due to changes in landuse, management, or climate. Yet, the amount and distribution of potentially mineralizable C present in soils of various types and the method by which this soil C fraction can best be quantified, are not well established.
