Characterisation of humic acid maturation by fluorescence spectroscopy and thermal analysis during composting of olive mill waste
Humic acids isolated from different stages of olive mill waste composting were investigated by Elemental analysis, Fluorescence spectroscopy and by Differential Scanning Calorimetry (DSC). The Elemental composition of these humic acids indicates an increase in aromatic structures during the composting. Indeed, the fluorescence results showed an increase in condensed aromatic ring systems. ...

Advanced characterization of algogenic organic matter, bacterial organic matter, humic acids and fulvic acids
Advanced characterization techniques of organic matter, including bulk organic characterization, size-exclusion chromatography, three-dimensional excitation–emission matrix, Fourier transform infrared spectroscopy, and fractionations using Amberlite XAD-8/4 resins, were used to investigate differences and similarities in the physicochemical properties of four different organic matter, ...

Effect of implementing organic farming on chemical and biochemical properties of an irrigated loam soil
Conventional agriculture can lead to reduced soil organic matter and depletion in soil fertility. For that reason, Food and Agriculture Organization of the United Nations (FAO) recommends organic matter incorporation to soils to increase their agronomic quality. This work studies the effect of the transition to organic farming on chemical and biochemical properties of a loam soil (Xerofluvent), ...
