Subject:
adsorption; biogeochemistry; color; dissolved organic carbon; hydrochemistry; mineral soils; pH; peat; rivers; runoff; silicon; soil horizons; statistical analysis; subwatersheds; sulfur; temporal variation; England
Abstract:
... This study compares the spatial and temporal variability of water colour for fifteen sub-catchments of the River Nidd, northeast England, in 1986 and 2006/2007. Between 1986 and 2006/2007, mean annual water colour increased in all the sub-catchments. However, there was considerable variation in the increase, which ranged from 22 to 155%. Statistical analysis revealed that the sub-catchments could ...

Subject:
Lolium; Luvisols; adsorption; biogeochemistry; carbon dioxide; clay; dissolved organic carbon; iron; kaolinite; mineralization; montmorillonite; plant residues; soil organic carbon
Abstract:
... The interaction of organic carbon (OC) with clay and metals stabilizes soil carbon (C), but the influence of specific clay-metal-OC assemblages (flocs) needs further evaluation. This study aimed to investigate the stability of flocs in soil as affected by external C inputs. Flocs representing OC-mineral soil fractions were synthesized using dissolved organic C (DOC) combined with kaolinite (1:1 la ...

Subject:
atmospheric deposition; ammonium salts; acidity; acidification; sodium nitrate; sulfur; upland soils; nitrogen; dissolved organic carbon; ecosystems; soil pH; biogeochemistry; acid-base balance; tree mortality; adsorption; Europe; North America
Abstract:
... Dissolved organic carbon (DOC) concentrations have risen in upland waters across large areas of Europe and North America. Two proposed drivers of these increases are (1) deposition of atmospheric pollutant nitrogen (N) with consequent effects on plant and decomposer carbon dynamics, and (2) soil recovery from acidification associated with decreasing sulphur deposition. Examination of 12 European a ...
