Podzols are highly influenced by the creation of a thick organic layers. A study was conducted to assess the Impact of succession on physicochemical properties of sod-podzolic soils during the last 60 years, Western European part of Russia, CFSNBR. Samples were taken from three representatives pedons: MGD, DOB (20–30 years) and DBAS (50–60 years). The data were processed and analyzed using standard methods in laboratory. Statistical analyzed was using ANOVA in accordance with GLM procedure (IBM SPSS) version 25. There was a significant (p < 0.05) difference in SOM, SOC, BD, P2O5 & K2O between succession stages & soil depth. However, there was no significant difference (p < 0.05) in Ph of (H20 & KCL). Among the succession stages, DBAS (50–60 years) resulted is the highest MOC, MOM & MTN. The greatest Mean P2O5 & K2O was found in DOB (20–30 years). The highest MBD and high pH acidity of KCl & H2O were recorded in MGD. Considering the soil depth, the amount of SOM, TN & SOC soil contained in the surface horizons (A and E) is comparatively higher than the subsurface horizons (B, C) confined in Pedon under DBAS (50–60 years). The correlation analysis showed a positive and highly significant correlation (p < 0.01) between SOC, SOM, K2O and negatively correlation in soil bulk density. It has been noted that overgrown plant in different succession stage have a profound impact on soil physicochemical properties.
