description

Nowadays, humic substances, the main organic components of soils and many fossil sediments, are becoming a material of wide application in agriculture and many technologies. Elemental, functional and spectral (UV, fluorescence, FTIR, 13C NMR spectra) analysis of industrially produced, as well as reference humic substances demonstrate significant differences in properties of humic substances depending on their origin, and thus, their potential application in agriculture. For authentication of humic substances’ origin, their elemental composition, as well as stable isotope (δC, δN, δO) ratios can be used.
