This work provides new data on the concentrations and export of chemical elements with soil waters of various plant communities of slope and valley-floodplain landscapes in the basin of upper reaches of the Ussuri River. The data show that the most nutrient-rich waters are formed in humus horizons of soils developed under elm-ash communities of valley-floodplain landscapes. More than 80% of the content of these elements are accumulated in the soil profile and support the functioning of communities. The waters of humus horizons of valley-floodplain communities are a potential source of elements entering river waters during periods of maximum precipitation. Soil waters of the mineral horizons of slope under mixed coniferous-deciduous communities are more acidic and transport relatively high amounts of dissolved organic carbon, iron, aluminum and phosphorus.
