The aim of this study was to evaluate the spatial variability of actual soil moisture (SMa), pH and bulk soil electrical conductivity (ECa) of soil surface horizons in the former Oleszek Mill Pond basin. Water mills are one of the first hydro-technological constructions in Poland. They appeared at the turn of the XI and XII centuries and became common in the XIII century. Construction and operation of water mills had influenced the transformation of the natural environment around them. Especially subject to transformations were the relief and water conditions. This research includes measurements of SMa, pH and ECa in soil surface horizons (0–30 cm). Actual soil moisture and bulk soil electrical conductivity were measured in situ using TDR Field Operated Meter – Easy Test FOM/mts and pH using CP-105 ELMETRON field pH-meter in 49 points located within the former mill pond basin. Differentiation of moisture, pH, and bulk soil electrical conductivity shows variability of the surface layer of the sediments accumulated in the former mill pond basin. On the other hand, the surface layer of the sediments does not show differences with regard to the division of the basin on the proximal, middle or distal part. The observed variability of spot-occurring extreme values is associated with the microrelief formed after the period of mill pond functioning (levees) or caused by local factors strongly modifying the surface of the biogenic plain within the basin, such as the seepages of water at the edge of the former water body.

The aim of the study has been to define the stocks and the basic properties of soil organic matter in agricultural-used soil sequence located in the former shoreline of disappearing lakes. The study area is located in the catchment of the Sumowskie Lakes, the Brodnica Lake District, North-Eastern Poland. The investigations involved preparation of five soil pits located in the south-western part of the former Sumowskie Lake bottom and on the southern slope of the adjacent kame hill. The greatest soil transformation is reflected in the quality and quantity of the soil organic matter. Indexes of organic matter quality and TOC stocks are significantly changing along the studied transect. The strongly humidified organic matter is found in mursh horizons. Gyttja layers above the groundwater level have a medium humification index. Horizons saturated with water are very low humidified. TOC stocks drop along the analysed soil sequence from the biogenic plain to the top of the kame hill.

The aim of the study was to assess the suitability of aerial photos for mapping the soils of dwindling lakes catchment areas. The study area is located in the North Poland, within the Brodnica Lakeland and it includes the direct catchment area of dwindling Sumowskie Lakes. There were three test area established for soil mapping. The photointerpretation was based on both immediate properties (colour of topsoil) for ploughed cultivated fields, and intermediate properties (vegetation and relief) for the areas of forests, shrubs or permanent pasture. The obtained results confirm the high usability of the cartographic materials such as aerial photographs and topographic maps for studies on specifications of areas such as the vicinities of dwindling lakes.
