Properties of soil and peat humic substances from Latvia
(2019) Klavins, M.; Purmalis, O.; Grandovska, S.; Klavina, L.
The acidity, elemental, functional and spectral (UV, fluorescence, IR spectra) characteristics of humic substances isolated from soils of different origin and peat in Latvia are described and compared with values common for humic substances of different origin, to evaluate the character of processes during humification. Substantial dependence of properties of humic substances on the humification conditions are found.
