Comparative analysis of black carbon in soils [PDF]

open access: yesGlobal Biogeochemical Cycles, 2001
Black carbon (BC), produced by incomplete combustion of fossil fuels and vegetation, occurs ubiquitously in soils and sediments. BC exists as a continuum from partly charred material to highly graphitized soot particles, with no general agreement on clear‐cut boundaries of definition or analysis. In a comparative analysis, we measured BC forms in eight

Aggregate‐occluded black carbon in soil

open access: yesEuropean Journal of Soil Science, 2006
Summary The great stability of black carbon (BC) in soils may not be solely attributable to its refractory structure but also to poor accessibility when physically enveloped by soil particles. Our aim was to elucidate the intensity of physical entrapment of BC within soil aggregates.

Quantification of black carbon in urban soils [PDF]

open access: yes, 2011
Black carbon (BC), which comprises partially combusted organic material such as char and soot, is a hazardous pollutant and contributor to global warming, but is also highly stable, and once deposited in soil contributes to long-term stocks of ...

Responses of Soil Collembolans to Land Degradation in a Black Soil Region in China

open access: yesInternational Journal of Environmental Research and Public Health, 2023
Land degradation in black soil regions has a significant effect on belowground systems, and Collembolans can adequately indicate environmental changes in the soil. However, there is currently a knowledge gap in the literature regarding the responses of soil Collembolans to land degradation.

Quantifying the Contribution of Sediment Load to Soil Detachment Rate by Sediment-Laden Rill Flow

open access: yes, 2017
Sediment load changes with downslope distance during rill erosion process, and thus quantifying the potential contribution of sediment load on soil detachment rate is essential to accurately model the rill erosion process.
