Influence of industrial effluence of the Selenga pulp and paper mill on soil and plants

Irrigation of Alluvial-Meadow soil by purified industrial effluence with a salt concentration of 758-1319 mg/l, including 437-745 mg/l sulfates, led to an increase in the content of exchangeable sodium, the accumulation of fewer nitrates, and a decrease in the activity of cellulose decomposition. However, the structurizing effect of the effluence is noted, and the C-HA/C-FA ratio widens. The yield of dry weight of grasses and their nutrition capacity does not differ from those in the variant with river-water irrigation.
