Total and labile organic carbon content in agroecological system [PDF]
, 2013 In an intercropping lettuce-carrot system submitted to crescent dosages of organic compost (0; 12; 24; 48 Mg ha-1) were monitored carbon from soil microbial biomass (MBC), labile carbon in fumigated soil (LCF), in non-fumigated soil (LCNF), in autoclaved soil (LCA) and total organic carbon (TOC) at 0-10 cm of depth. Pasture and forest areas surrounding

A cross-system analysis of labile dissolved organic carbon [PDF]
Marine Ecology Progress Series, 1995 Abstract. Concentrations of recalcitrant and bioavailable dissolved organic carbon (DOC) and their seasonal variations were investigated at three stations in Tokyo Bay, Japan, and in two freshwater sources flowing into the bay. On average, recalcitrant DOC (RDOC), as a remnant of DOC after 150 days of bottle incubation, accounted for 78% of the total ...

Microbial diversity and the lability of dissolved organic carbon [PDF]
Proceedings of the National Academy of Sciences, 2014 Marine metagenomics is steadily unveiling the phylogenetic diversity and metabolic potential of the microbial plankton. Our awareness that planktonic Bacteria and Archaea (bacterioplankton) dominate this diversity only underscores our inability to answer a basic ecological question: what are bacterioplankton eating?

Hydropyrolysis: implications for radiocarbon pre-treatment and characterization of Black Carbon [PDF]
, 2010 Charcoal is the result of natural and anthropogenic burning events, when biomass is exposed to elevated temperatures under conditions of restricted oxygen.

Assessment of Labile Organic Carbon in Soil Using Sequential Fumigation Incubation Procedures. [PDF]
J Vis Exp, 2016 Management practices and environmental changes can alter soil nutrient and carbon cycling. Soil labile organic carbon, a readily decomposable C pool, is highly sensitive to disturbance. It is also the primary substrate for soil microorganisms, which is fundamental to nutrient cycling.

Distribution of labile dissolved organic carbon in Lake Michigan [PDF]
Limnology and Oceanography, 1990 Bioassay‐measured, labile dissolved organic carbon (LDOC) concentrations were compared in near‐bottom and near‐surface Lake Michigan water between April and October 1986. In five of seven experiments, the LDOC concentration was higher in near‐bottom water.

Soil labile organic carbon indicating seasonal dynamics of soil organic carbon in northeast peatland
Ecological Indicators, 2022 Peatlands have persisted as massive carbon pool in terrestrial ecosystem. Labile organic carbon (LOC) plays a vital role in carbon cycling in high-latitude peatlands, which is an important indicator of seasonal soil organic carbon (SOC) dynamics. However, the contributions of LOC fractions are poorly understood.

Alpine grassland soils contain large proportion of labile carbon but indicate long turnover times [PDF]
, 2011 Alpine soils are expected to contain large amounts of labile carbon (C) which may become a further source of atmospheric carbon dioxide (CO2) as a result of global warming.

Warming mineralises young and old soil carbon equally [PDF]
, 2006 The temperature sensitivity of soil organic carbon decomposition is critical for predicting future climate change because soils store 2-3 times the amount of atmospheric carbon.

Microbial formation of labile organic carbon in Antarctic glacial environments [PDF]
Nature Geoscience, 2017 Bioavailable glacial carbon has been thought to be largely ancient or anthropogenic. Analyses of carbon dynamics in an Antarctic supraglacial stream reveal that non-photosynthetic production relies on organic carbon from photosynthetic microbes.
