“…Another important issue in the context of the discussed low SOC stocks is human-induced erosional processes which lead to the degradation of soils and depletion in SOC content and shallowing of humus horizons (Sinkiewicz, 1998;Podlasiński, 2013;Świtoniak et al 2016;Radziuk and Świtoniak, 2022;Sowiński et al 2023). The influence of slope processes on the properties of the studied soils is evidenced by their morphology -nearly half of them (34 profiles) had Bt horizons directly below plough horizons -which is the effect of erosive truncation.…”

Clay-illuvial soils (Luvisols or Retisols in WRB) are the most widespread component of soil cover in Poland. Due to common occurrence and relatively high fertility they are crucial for food production. Agricultural use of these soils, however, leads to strong alterations and, in many cases, their degradation. This is especially important in young morainic landscapes of northern Poland. Hummocky and undulating relief combined with agricultural use, leads to truncation of clay-illuvial soils and generally affect the quality of humus horizons and soil organic carbon (SOC) content. The aim of the presented study is to assess the overall SOC stocks in plough horizons of clay-illuviated soils and their differentiation between their most common subtypes (according to Polish Soil Classifi cation 2019). SOC stocks were calculated for 72 soil profi les. The average stocks were low -3.28 kg•m -2 which may be related to both: natural conditions and strong anthropogenic alterations. Based on the obtained results separate subtype attributes, although express the variability of clay-illuvial soils, do not refl ect the diversity of humus pools. However, it can be stated that SOC stocks differ statistically in particular complex subtypes. The highest SOC stocks (4.12 kg•m -2 ) were recorded in the humic stagnogleyic clay-illuvial soils (Stagnic Luvisols/Retisols in WRB) characterized by relatively high soil moisture and a low erosive transformations. Truncated pedons (Ap-Bt-C(k)) were divided into two common subtypes -eroded humic clay-illuvial soils and eroded clay-illuvial soils (Haplic Luvisols). Eroded humic subtype had quite high average SOC stocks -3.61 kg•m -2 , the second subtype had extremely low carbon pools -1.40 kg•m -2 . Such high diversity may result from different pace of erosion in particular profi les and regenerative, sustainable management (e.g. reduced ploughing, vineyards, grassland) leading to the rebuilding of SOC stocks in many of studied eroded humic pedons. Low stocks (2.24 kg•m -2 ) were also noticed in typical clay-illuvial soils which humus horizons were also degraded by erosion. A slight erosional alterations characterized subtype of texturally contrasted humic clay-illuvial soils (Abruptic Luvisols / Haplic Planosols) with average stocks -3.57 kg•m -2 . For further research larger database is necessary. Carbon stocks in the deeper horizons should also be investigated.

Purpose Particle size distribution (PSD) assessment, which affects all physical, chemical, biological, mineralogical, and geological properties of soil, is crucial for maintaining soil sustainability. It plays a vital role in ensuring appropriate land use, fertilizer management, crop selection, and conservation practices, especially in fragile soils such as those of the North-Western Himalayas. Materials and methods In this study, the performance of eleven mathematical and three Machine Learning (ML) models used in the past was compared to investigate PSD modeling of different soils from the North-Western Himalayan region, considering that an appropriate model must fit all PSD data. Results and discussion Our study focuses on the significance of evaluating the goodness of fit in particle size distribution modeling using the coefficient of determination (R2adj = 0.79 to 0.45), the Akaike information criterion (AIC = 67 to 184), and the root mean square error (RMSE = 0.01 to 0.09). The Fredlund, Weibull, and Rosin Rammler models exhibited the best fit for all samples, while the performance of the Gompertz, S-Curve, and Van Genutchen models was poor. Of the three ML models tested, the Random Forest model performed the best (R2 = 0.99), and the SVM model was the lowest (R2 = 0.95). Thus, the PSD of the soil can be best predicted by ML approaches, especially by the Random Forest model. Conclusion The Fredlund model exhibited the best fit among mathematical models while random forest performed best among the machine learning models. As the number of parameters in the model increased better was the accuracy.

The plant Silybum marianum (L.) Gaertn. has been used in a preliminary study to investigate its phytoremediation potential in moderately and heavily Cd-polluted Greek soils. For this purpose, a pot experiment was carried out using four soil treatments, two from agricultural and two from urban areas, contaminated with 3 and 30 mg of Cd per kg of soil. The modified Bureau of Community Reference (BCR) fractionation method was used to determine Cd levels in the soil fractions. The water-soluble, available-DTPA extractable, total and pseudo-total concentrations of Cd were also evaluated and attempts to find relationships between Cd soil fractions and Cd levels in the parts of the cultivated plants were made. Significant correlations among Cd soil fractions, Cd plant parts, and soil physicochemical parameters were obtained and discussed. High Cd translocation and accumulation rates were observed mainly in the root and the lower part of the stems, while in flowers and seeds no Cd was detected, leading to the conclusion that the high-value product contained in the seeds maintains its quality and is free of contaminants. The results are satisfactory indicating Silybum marianum (L.) Gaertn. as a promising plant for remediation practices in Cd-contaminated Mediterranean soils, promoting the principles of circular economy.
