Geogenic organic carbon in terrestrial sediments and its contribution to total soil carbon [PDF]

open access: yesSOIL, 2021
Geogenic organic carbon (GOC) from sedimentary rocks is an overlooked fraction in soils that has not yet been quantified but influences the composition, age, and stability of total organic carbon (OC) in soils.

Chemical characterization of water-soluble organic carbon aerosols at a rural site in the Pearl River Delta, China, in the summer of 2006 [PDF]

open access: yes, 2009
Online measurements of water-soluble organic carbon (WSOC) aerosols were made using a particle-into-liquid sampler (PILS) combined with a total organic carbon (TOC) analyzer at a rural site in the Pearl River Delta region, China, in July 2006.

Development of a fully coupled biogeochemical reactive transport model to simulate microbial oxidation of organic carbon and pyrite under nitrate‐reducing conditions [PDF]

open access: yes, 2018
©2018. American Geophysical UnionIn regions with intensive agriculture nitrate is one of the most relevant contaminants in groundwater. Denitrification reduces elevated nitrate concentrations in many aquifers, yet the denitrification potential is limited

Geochemistry of reduced inorganic sulfur, reactive iron, and organic carbon in fluvial and marine surface sediment in the Laizhou Bay region, China [PDF]

open access: yes, 2015
Understanding the geochemical cycling of sulfur in sediments is important because it can have implications for both modern environments (e.g., deterioration of water quality) and interpretation of the ancient past (e.g., sediment C/S ratios can be used ...

Losses of soluble forms of organic carbon in relation to different agro-technical treatment of meadows

open access: yesSoil and Water Research, 2016
Studies were performed to determine the loss of soluble forms of organic carbon in differently used meadows on mineral soil. In a long-term experiment two variants were distinguished: a productive meadow (N120-AN and N120-CN) and a non-productive one (Kp-
