Journal ArticleDOI
New insights into organic-mineral particles: composition, properties and models of molecular structure
H.-R. Schulten,Peter Leinweber +1 more
TL;DR: In this article, a review of methodological advances and the characteristic features of the chemical composition of organic matter in these different fractions are summarized and compared for the first time, and the resulting potential, and limits, for modelling of organic macromolecules, organic-mineral particles and mineral surfaces are delineated.
Journal ArticleDOI
Transport of bacteria from manure and protection of water resources
Adrian Unc,Michael J. Goss +1 more
TL;DR: In this article, the authors investigated how the properties of such a complex environment as the soil-manure medium impact the persistence of bacteria within the vadose zone, and found that manure can change the partitioning of precipitation water between infiltration (enhanced by solid manure) and surface runoff (stimulated by liquid manure).
Journal ArticleDOI
Enhancement of copper and cadmium adsorption on kaolin by the presence of humic acids.
TL;DR: HAs were found to enhance the metal adsorption capacity of mineral surfaces, in particular kaolin, and this enhancement was also observed in the competitive adsorptive capacity of copper and cadmium on kaolin and kaolin-HA complex.
Journal ArticleDOI
The role of sorbed humic substances on the distribution of organic and inorganic contaminants in groundwater
E.M. Murphy,J.M. Zachara +1 more
TL;DR: In this paper, it was shown that hydrophobic adsorption, rather than phase partitioning, is the primary sorption mechanism for neutral organic molecules on these particle coatings and that mineral-bound humic materials may, therefore, provide a major sink for the removal of contaminants in groundwater.
Journal ArticleDOI
Impact of Long-Term No-Tillage and Cropping System Management on Soil Organic Carbon in an Oxisol: A Model for Sustainability
Ademir Calegari,William L. Hargrove,Danilo dos Santos Rheinheimer,Ricardo Ralisch,Daniel Tessier,Stéphane de Tourdonnet,Maria de Fátima Guimarães +6 more
TL;DR: In this article, the authors compared conventional tillage (CT) and no-tillage (NT) management systems and various winter cover crop treatments in a Rhodic Hapludox in southern Brazil.

Information Provided on Humic Substances by E4/E6 Ratios
TL;DR: In this article, it was shown that the ratio of optical densities or absorbances of dilute, aqueous humic and fulvic acid solutions at 465 and 665 nm is mainly governed by the particle size (or particle or molecular weight).

Carbon-13 nuclear magnetic resonance spectrometry. Chemical shifts for the paraffins through C9
L. P. Lindeman,J. Q. Adama +1 more
Journal ArticleDOI
Macromolecular Structures of Humic Substances
Kunal Ghosh,Morris Schnitzer +1 more
TL;DR: This paper investigated humic substances by surface pressure and viscosity measurements at different pHs and neutral salt concentrations to elucidate their macromolecular configurations and observed that such configurations were not unique; they varied with the changes in the medium.
Journal ArticleDOI
Sorption of metals on humic acid
H. Kerndorff,Morris Schnitzer +1 more
TL;DR: In this paper, the sorption of eleven metals on the humic acid of an aqueous solution containing Hg(II), Pb, Cu, Al, Ni, Cr(III), Cd, Zn, Co and Mn, was investigated with special emphasis on effects of pH, metal concentration and HA concentration.
