Multiparametric analysis of soil properties in the drained forest bogs of Western Siberia

The application of multiparametric statistical methods has confirmed that peat soils are different in the degree of their drainage and properties because of their modification during a 20–25 year period of artificial drainage operation. The following sequence represents the relative significance of the contribution to the soil changes of the parameters studied: groundwater table > air capacity > pH > 0T > Eh > water-soluble: C > Fe3+ > NH 4 + and the activity of soil oxidoreductases in the following sequence: peroxidase > catalase > dehydrogenase. The necessity to supplement the substantive-genetic principle of the classification of drained peat soils with characterization of their water regime is substantiated.
