| Abstract: | Dissolved organic matter was studied in soils of the felled areas in fir-spruce forests of the southern Sikhote-Alin Ridge. After cutting of the forest, the molecular-mass characteristics of the dissolved organic matter in the soils changed: its molecular structure became simpler, and the degree of aromatic polycondensation and the capacity for the formation of complexes with Fe and Al decreased. |
