Changes in Several Properties of Humic Acids after Application of Exogenous Organic Materials

Popis výsledku v původním jazyce

Exogenous organic materials (biochar, compost, digestate, lignite, and lignohumate) were applied to a Haplic Cambisol with the aim to improve soil chemical properties and soil organic matter quality. Ultraviolet- visible spectroscopy was used for comparing alkali-extracted humic substances. Elemental composition and specific peaks in Fourier transformed infrared (FT-IR) spectra were used for comparison of the isolated HAs. All the HA samples contained alkyl, aromatic, carboxyl, amido, amino, and carbonyl groups. The highest content of aliphatic C-H groups in the HAs after compost and lignohumate applications and the prevalence of aromatic groups in the HAs after biochar and lignite applications were estimated. Based on the differences in FT-IR spectra, stability indexes of HAs were calculated.
