Removal of mineral components and organic matter by the wetland water is evaluated using the observations on the Pulozero oligotrophic bog (the Kola Peninsula). Precipitation is a source of mineral components for bogs, its mean annual mineralization is 26.8 mg/dm 3 . The average annual inflow of mineral components per bog unit area is 13.0 t/km 2 . Their mean annual channel flow modulus (14.8 t/km 2 ) is 38% greater than the modulus of their total loss (10.7 t/km 2 ) from the wetland (by infiltration, discharge, and accumulation). It is explained by the partial discharge of groundwater into the stream channel. The accumulation of mineral components within a peat deposit is equal to 2.3 t/km 2  per year, or 17.7% of fallen ones. The concentration of organic matter in the water of a hummock-ridge complex is on average equal to 140.3 mg/dm 3 , varying from 68.2 to 200.8 mg/dm 3 . The modulus of organic substance loss within the complex is on average equal to 38.2 t/(km 2  year). Its annual channel flow is 12.5 t/(km 2  year). The accumulation of organic matter within the peat deposit reaches 25.7 t/(km 2 year), or 67.3% of the organic substance mass formed within the bog microlandscape during a year.
