Black Carbon (BC) may significantly affect nutrient retention and play a key role in a wide range of biogeochemical processes in soils, especially for nutrient cycling. Anthrosols from the Brazilian Amazon (ages between 600 and 8700 yr BP) with high contents of biomassderived BC had greater potential cation exchange capacity (CEC measured at pH 7) per unit organic C than adjacent soils with low BC contents.Synchrotron-based near edge X-ray absorption fine structure (NEXAFS) spectroscopy coupled…

Mineralogical controls on soil black carbon preservation

Black carbon (BC) has long been considered a chemically resistant component of soil organic carbon (SOC). However, there is substantial evidence that the chemistry of most C compounds is less

Long-term black carbon dynamics in cultivated soil

Black carbon (BC) is a quantitatively important C pool in the global C cycle due to its relative recalcitrance compared with other C pools. However, mechanisms of BC oxidation and accompanying

Oxidation is Key for Black Carbon Surface Functionality and Nutrient Retention in Amazon Anthrosols

Aims: Soil black carbon (BC) has been shown to possess large amounts of cation exchange sites and surface charge, and is viewed as a potential soil amendment to improve nutrient retention and for

Anion exchange capacity of biochar

Biochar has gained recent interest as a soil amendment and agent for carbon sequestration. Some biochars have significant levels of anion exchange capacity (AEC), which may reduce leaching of anionic

Temperature sensitivity of black carbon decomposition and oxidation.

Carbon loss and potential cation exchange capacity (CECp) significantly correlated with O/C ratios and change in O-C ratios, suggesting that oxidative processes were the most important mechanism controlling BC decomposition in this study.



An improved thermal oxidation method for the quantification of soot/graphitic black carbon in sediments and soils.

Improvements presented in this work allow for the accurate and precise measurement of GBC in complex organic and mineral matrixes by eliminating the interference caused by the presence of CBC, residual non-BC OC and minerals, or by the formation of condensation products that could account for as much as 4-6% of total OC.

Carbon K‐Edge NEXAFS and FTIR‐ATR Spectroscopic Investigation of Organic Carbon Speciation in Soils

Soil organic matter (SOM) is a fundamental component of soil and the global C cycle. We used C (1s) near-edge x-ray absorption fine structure (NEXAFS) and synchrotron-based Fourier transform

Charred organic carbon in German chernozemic soils

Burning vegetation produces partly charred plant material which subsequently could contribute to the highly refractory proportion of soil organic matter. The presence of charred organic carbon (COC)

Assessing the combined roles of natural organic matter and black carbon as sorbents in sediments.

We hypothesized that two mechanisms, absorption into natural organic matter and adsorption onto combustion-derived black carbon (BC), act in parallel to bind polycyclic aromatic hydrocarbons (PAHs)

New directions in black carbon organic geochemistry

Carbon isotope geochemistry and nanomorphology of soil black carbon: Black chernozemic soils in central Europe originate from ancient biomass burning

A common paradigm is that chernozem soils developed in the Holocene under grassland steppes, with their formation largely determined by three factors, parent material, climate and faunal mixing. For

The chemistry and nature of protected carbon in soil

The nature of organic carbon in the < 2, 2–20, 20–53, 53–200, and 200–2000 mu m fractions of four surface soils was determined using solid state 13C nuclear magnetic resonance (n.m.r.) spectroscopy

Black carbon in soils and sediments: Analysis, distribution, implications, and current challenges

This review highlights the ubiquity of black carbon (BC) produced by incomplete combustion of plant material and fossil fuels in peats, soils, and lacustrine and marine sediments. We examine various
