Abstract: The aim of this paper is to present the changes in magnetic and soil parameters that characterize the processes occurring in the degraded chernozem formed in loess from Miechow area. The study used magnetic properties of soil and the method of measuring reactivity pH, loss on ignition and carbonate content in the soil. The A and ABbr(Bt) horizons have similar values of the magnetic parameters: χ, χARM and χfd%. Both horizons [A and ABbr(Bt)] are enriched in strongly magnetic iron oxides (maghemit) with low values of magnetic coercivity. A parent rock (loess from the Miechow area) contains hematite with low magnetization and high magnetic coercivity. In the study the parameters of hysteresis loop and the temperature-dependent parameter: SIRM(T) and κ(T) were used to identify the magnetic minerals present in the soil profile. Magnetic susceptibility and its dependence on frequency were used to identify the enrichment of soil horizons in the fraction of magnetic particles formed during pedogenesis. Large magnetic enrichment in horizons A and ABbr(Bt) is associated with a high content of organic matter in the upper levels of the soil, for which the parameter of loss on ignition point to 8–10% of the organic matter.
