The chemical composition of snow water of spruce forests of the middle taiga
The spatial and temporal dynamics of the chemical composition of precipitation in the form of snow, throughfall under the canopy of old-growth spruce forests of middle taiga is traced. It is noted that the average monthly deposition of mineral components with snow water always low. Higher deposition values of macro- and micro-components noted in December. Snow waters are hydrocarbonate-calcium and low-acidic, with pH 5.2±0.3. Spruce stands transform the chemical composition of snow mainly during snowmelt in December and March, increasing the concentration of both macro- and micro-components. The chemical composition of snow throughfall under spruce dominated dissolved organic carbon.
