This paper aims to assess the usefulness of magnetic susceptibility measurements in pedological studies of mill pond sediments. The study area includes the former Turznice mill pond basin located in the south-eastern part of the Grudziadz Basin. Four soil profiles were selected within the transect located along the longitudinal axis of the basin. The following soil properties were determined in the collected samples: bulk density, particle size distribution, pH, content of carbonates, approximate content of organic matter (LOI), total organic carbon (TOC), total nitrogen (Nt), and the pseudo-total contents of metals (Fe, Mn, Cu, Zn, Pb, Ni, Cd). The obtained results were correlated with the specific (mass) magnetic susceptibility (chi). This study revealed that the variability of the soil cover in the basin was driven by different sedimentation conditions. The different composition of natural terrace deposits versus mill pond sediments has been well reflected in the magnetic properties. However, the possibility cannot be excluded that a pedogenic (gleyic) process is the key factor causing the vertical variability of magnetic properties in studied soils.
