Variations in radiocarbon ages of various organic fractions in core sediments from Erhai Lake, SW China [PDF]

open access: yes, 2003
Radiocarbon dating was performed for the extracted organic fractions (cellulose-rich and humic acid fractions of plant fragment; fulvic acid, humic acid and humin fractions of humus substance) and shell from core sediments of the Erhai Lake, SW China ...

Rhizosphere and non-rhizosphere soil organic carbon and its labile fractions in alpine desertified grassland affected by vegetation restoration

open access: yesPlant, Soil and Environment
Grasslands are the predominant land use type in China, which is currently encountering significant desertification issues. Consequently, restoring grassland vegetation has important implications for terrestrial carbon (C) levels and, consequently, the ...

Effects of Continuous Manure Application on the Microbial Community and Labile Organic Carbon Fractions

open access: yesAgriculture, 2023
The application of organic materials contributes to the sustainable development of agriculture. Increased manure inputs have a fundamental effect on the composition and dynamics of soil organic carbon (SOC). In this study, we conducted a 10-year field experiment in Changchun, Jilin, Northeast China, to investigate the effects of manure addition on soil

Content of soil organic carbon and labile fractions depend on local combinations of mineral-phase characteristics [PDF]

open access: yesSOIL, 2022
Abstract. Soil organic matter (SOM) is an indispensable component of terrestrial ecosystems. Soil organic carbon (SOC) dynamics are influenced by a number of well-known abiotic factors such as clay content, soil pH, or pedogenic oxides. These parameters interact with each other and vary in their influence on SOC depending on local conditions.

Dynamics of labile soil organic carbon during the development of mangrove and salt marsh ecosystems

open access: yesEcological Indicators, 2021
Labile fractions of soil carbon pools are sensitive to environmental changes, which would influence the stabilization of soil carbon. However, it is unclear whether the dynamics of labile organic carbon (LOC) and soil organic carbon (SOC) are coupled and

Effects of long-term fertilisation on soil organic carbon sequestration after a 34-year rice-wheat rotation in Taihu Lake Basin

open access: yesPlant, Soil and Environment, 2021
To evaluate the long-term effects of fertilisation on soil organic carbon (SOC) sequestration in rice-wheat cropping ecosystems, SOC dynamics, stocks and fractionation were determined.

Effect of land use and organic matter on nitrogen and carbon labile fractions in a Typic Hapludult [PDF]

open access: yesJournal of Degraded and Mining Lands Management, 2017
A study that was aimed to determine the effect of organic matter from groundnut and maize biomass on the availability of N and C labile fraction was conducted in laboratory and glasshouse, Iletry, Malang. Research used randomized block design with three replications. The first factor was land use : (1).
