fulvic acid - Opis:
- The study presented here concentrates on the characteristics of the humous compounds of humic and fulvic acid fractions of ß-humus, originating from the typologically differentiated soils (podzolic soil and chernozem). The soils were chosen so as to emphasize differences between chemical structure and degree of aromatic nucleus condensation in the humous acids isolated from them. It was found that the structure of the humous substances isolated from the podzolic soil is characterised by the lowest degree of condensation of the aromatic nucleus and the lowest polymerisation, while the humous acids from the chernozem are characterised by the highest degree of condensation of the aromatic nucleus and the strongest polymerisation.
