The assessment of the state of the specially protected natural areas (SPNA) of the regional (the “Pizhemsky” zakaznik)
and of the federal significance (the “Nurgush” nature reserve) located in the Kirov region is given in the article.
The predominant type of soils of the SPNRs under the study is alluvial turf soils, with strongly and slightly acidic reaction
of the medium. The content of organic matter in the soils of the “Pizhemsky” zakaznik varies from 3.1 to 4.7% for
meadow and from 1.2 to 7.3% for forest phytocenoses. For the territory of the “Nurgush” nature reserve the content of
organic matter in the soils of forest phytocenoses ranges from 2.0 to 6.7%. The content of nitrate nitrogen in the soils of
the studied SPNR corresponds to the average level of soil supply with nitrogen. A decrease in the content of ammonium
nitrogen down the soil profile was noted for the studied sites. The content in the soils of heavy metals (Zn, Mn, Fe, Cu, Pb,
Cd) is at a stable level within the ecological norm. In all studied soil samples, the main content of metals was manganese
and iron, both for active and for gross form. The maximum content of active forms of manganese and iron is found in soil
samples of the upper horizons. Insignificant amounts of copper, lead and cadmium indicate the absence of man-caused
contamination of the soil in these sites. Among the gross forms of heavy metals, iron predomination in soil samples of
the upper and lower horizons was recorded. The maximum content of gross iron form was noted in the samples from the
territory of the “Nurgush” nature reserve.
