Modelling carbon overconsumption and the formation of extracellular particulate organic carbon [PDF]
Biogeosciences, 2007 During phytoplankton growth a fraction of dissolved inorganic carbon (DIC) assimilated by phytoplankton is exuded in the form of dissolved organic carbon (DOC), which can be transformed into extracellular particulate organic carbon (POC).

Remote Sensing Observation of Particulate Organic Carbon in the Pearl River Estuary
Remote Sensing, 2015 River estuaries are connectors of terrestrial and marine ecosystems. Riverine particulate organic carbon (POC) is discharged into oceans after a series of biogeochemical reactions in estuaries.

Dissolved carbon flow to particulate organic carbon enhances soil carbon sequestration
SOIL. Particulate organic carbon (POC) and mineral-associated organic carbon (MAOC), which are two primary components of the soil carbon (C) reservoir, have different physical and chemical properties as well as biochemical turnover rates. Microbial necromass

Distribution, Fluxes, and Balance of Particulate Organic Carbon in the Arctic Ocean
Oceanology, 2019 Particulate organic carbon (POC) is one of main component of carbon cycle in the Ocean. In this study an attempt to construct a picture of the distribution and fluxes of POC in the Arctic Ocean adjusting for interchange with the Pacific and Atlantic Oceans has been made.

Estimating soil particulate organic carbon through total soil organic carbon
Ciencia del SueloParticulate soil organic carbon (POC) is sensitive to management changes, and a good soil health indicator. However, its determination is tedious and time consuming. Given POC changes represent most of total organic carbon (TOC) variation due to soil use,

Long-term application of straw and biochar improves soil carbon fractions, enzyme activity, and tomato yield under continuous greenhouse cultivation [PDF]
Frontiers in Plant ScienceIn recent years, there has been increasing emphasis on the sustainable organic material reutilization, including straw and biochar. This study investigates the effects of prolonged applications of straw (R), biochar (B), and their combination (RB) on ...

Soil organic carbon and particulate carbon in water in riparian systems under different land use
Terra Latinoamericana, 2021 Overexploitation of hydric resources and lack knowledge of interactions between riparian vegetation, water and soil, generates loss of environmental services and ecological degradation in many mountainous riparian environments. In order to characterizing
