Spectral characterization of selected humic substances
13C NMR spectroscopy Fourier transform infrared spectroscopy (FTIR) humates lignohumate steady-state fluorescence spectroscopy UV-VIS
2015/3/10
Current concern for soil quality has stimulated research on soil organic matter (OM). Humic substances (HS) of different origin were compared applying ultraviolet-visible spectroscopy, Fourier transfo...
Effect of different levels of humic acids on the nutrient content, plant growth, and soil properties under conditions of salinity
humic acids nutrient content plant growth salinity soil properties
2015/3/3
In this study, the effects were investigated of salinity, foliar and soil applications of humic substances on the growth and mineral nutrients uptake of Corn (Hagein, Fardy10), and the comparison was ...
Spectroscopic Characteristics of Humic Acids Originated in Soils and Lignite
humic acids UV-VIS FTIR and SFS spectroscopy
2015/3/1
The aim of our work was to characterise the stability, humification degree, and principal classes of fluorophores in humic acids isolated from different matrices. Soil humic acids were isolated from a...
Molecular size distribution and hydrophilic and hydrophobic properties of humic acids isolated from forest soil

2015/1/30
The aim of the present paper was to determine hydrophilic and hydrophobic properties and the degree of polydispersity of humic acids depending on their degree of maturity and the properties of the pla...
Phosphorus fractions in arable and mountain soils and their humic acids
inorganic P organic P soil types humic acids 31P NMR
2015/1/30
Soil phosphorus (P) can exist in various inorganic (Pi) and organic forms (Po). Specific determination of Pi can be obtained by fractionate methods. However, the discrimination between the chemically ...
Mobility of Iron-Cyanide Complexes in a Humic Topsoil under Varying Redox Conditions
Iron-Cyanide Complexes a Humic Topsoil Varying Redox Conditions
2009/12/2
The potentially toxic Fe-CN complexes ferricyanide, [FeIII(CN)6]3−, and ferrocyanide, [FeII(CN)6]4−, undergo a variety of redox processes in soil, which affect their mobility. We carried o...
