    The basins of former mill ponds are a common element of the cultural landscape, while soil science studies focusing on mill pond sediments remain relatively rare. One of the key properties relevant to the sustainable management of these sites is the content and stocks of organic carbon in the soils developed from the mill pond sediments. Therefore, the study aimed to analyze the total organic carbon (TOC) and total nitrogen content, as well as its stocks in the studied soils, the share of the labile fractions of these compounds in relation to the environmental factors influencing these properties and finally their potential changes over time (stability). The obtained results confirmed that the studied soils (mostly classified as Gleyic Fluvisols and Fluvic Phaeozems) are characterized by a high amount of TOC. This manifests in the large TOC stocks in the upper 50 cm (mean = 18.1; min = 8.35; max = 35.5 kg m−2) and in the whole soil profiles (mean = 43.7; min = 10.6; max = 93.6 in kg m−2). The dissolved organic carbon share in TOC content was slightly over 1% on average (mean = 1.06; min = 0.19; max = 4.75) and the specific UV absorbance averaged about 2.40 L mg C−1 m−1, indicating the relatively large proportion of recalcitrant organic fractions and low potential for further degradation.

    Understanding pedodiversity in the historical park: implications of human impact
    (Springer, 2025-08-12) Hulisz, Piotr; Pindral, Sylwia; Dziemińska, Anna; Kot, Rafał; Michalski, Adam; Dąbrowski, Michał; Markiewicz, Maciej
    Purpose This research explores how human activity, particularly in historical parks, has influenced soil diversity (pedodiversity) and altered soil properties over time, focusing on the Lubostroń palace park in Poland. Methods In 2019, field research included 34 soil drillings and 7 soil pits, yielding 29 samples analyzed for particle size distribution, pH, CaCO3, TOC, TN, available phosphorus, and magnetic susceptibility. A pedodiversity map was created based on an updated, WRB-reclassified 1:5,000 historical soil-agricultural map, refined using fieldwork, laboratory analyses, and the integration of current land use data. The pedodiversity index (PI) was calculated using Patch Richness and Shannon’s Diversity Index, ranked by the Jenks method, following PCA and bonitation procedures. Results The analyses revealed significant soil modifications, such as deposition of technic hard materials, heap materials, artifacts, and alterations in pH, phosphorus levels, and organic carbon content. These changes reflect diverse historical land uses, including residential, agricultural, and industrial activities. Spatial analyses showed that Brunic Arenosols and Brunic Regosols cover 46% of the park, while heavily transformed Technosols occupy 8.6% in built-up zones. High pedodiversity index values were primarily found in the central and eastern parts of the park, indicating intense anthropogenic influence. Conclusion The study demonstrated that over 200 years of intensive and multidirectional human activity strongly influenced soils in the Lubostroń park. The human impact led to various transformations that shaped the spatial pattern and increased soil diversity (pedodiversity), which was not recorded on the 1:5,000 historical soil-agricultural map. The applied approach enabled a detailed identification of these changes, which may support the reconstruction of past environmental conditions and sustainable park management.
