The Content and Stocks of Organic Carbon and Labile Carbon Fractions Are Key Properties for the Sustainable Use of Terrestrialized Former Mill Ponds
(MDPI, 2026) Mendyk, Łukasz; Glina, Bartłomiej; Glatzel, Stephan; Markiewicz, Maciej; Sewerniak, Piotr; Ukalska-Jaruga, Aleksandra
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.
Salinity-driven evolution of psychrotolerant Bacillus velezensis S_51 strain reveals metabolic adaptations to osmotic stress and enhanced glycine betaine production
(Springer Nature, BioMed Central (BMC), 2026) Goszcz, Aleksandra; Musiałowski, Marcin; Ciuchciński, Karol; Stasiuk, Robert; Błaziak, Kacper; Furtak, Karolina; Junkier, Aleksandra; Bernatowicz, Anna; Schiavon, Michela; Dębiec-Andrzejewska, Klaudia
Soil salinisation limits agricultural productivity by disrupting microbial homeostasis and plant–microbe interactions. Osmoprotectants, including glycine betaine, play a crucial role in protecting microbial cells against osmotic stress by stabilising cellular structures and maintaining osmotic balance. To optimise microbial production of glycine betaine, adaptive laboratory evolution (ALE) was applied to Bacillus velezensis S_51 under increasing sodium chloride (NaCl) concentrations, providing insight into the underlying metabolic and genomic adaptations. After 10 sequential passages (500 generations), the evolved strain exhibited an adaptive shift in growth preference towards higher salinity from 0% to 4% (0.68 M) NaCl, indicating niche specialisation. This adaptation was accompanied by a pronounced increase in osmoprotection, with intracellular glycine betaine levels rising by ~262-fold relative to the ancestral strain, reaching to 882.25 ± 68.58 µM g⁻¹ DM. Metabolic profiling revealed a non-uniform reorganisation of substrate utilisation, with differentiation between ancestral (P1) and evolved (P10) strains largely driven by a limited subset of compounds (~62% contribution of key substrates). The evolved strain showed a ~ 4–5-fold increase in the number of effectively utilised carbon (C) and nitrogen (N) sources, with selective enhancement of specific amino acids (e.g., L-serine, L-aspartic acid) and reduced utilisation of several carbohydrates and hexose phosphates, indicating redistribution of substrate utilisation profiles under osmotic constraints. Functional trait analysis showed increased biofilm formation and elevated indole-3-acetic acid (IAA) production (from 0.1 to 0.13 µg mL⁻¹), while siderophore production remained stable. Genomic analysis identified mutations in key regulatory genes, including kapB, spo0A, and comP, suggesting an association between phenotypic shifts and regulatory network reconfiguration. Together, these results demonstrate that ALE drives coordinated metabolic, physiological, and regulatory adaptation, enhancing microbial fitness under saline conditions and supporting its application in saline soil biotechnologies.
Reconstructing missing data by comparing imputation and interpolation techniques: applications for long-term groundwater monitoring
(Nature Portfolio, 2026) Bronowicka-Mielniczuk, Urszula; Mielniczuk, Jacek; Skowron, Piotr
Missing data is a pervasive challenge in environmental monitoring, severely hindering reliable analysis and effective water resource management. This study addresses this issue in the context of the EU Nitrates Directive (91/676/EEC), focusing on the proportion of groundwater monitoring sites expected to exceed the regulatory limit of 50 mg NO₃⁻/L. Overall, 57% of observations were missing, with 99% of monitoring stations experiencing data gaps over the 2000–2024 study period. Six reconstruction techniques were evaluated: k-nearest neighbours, multiple imputation by chained equations, missForest, natural neighbour, inverse distance weighting, and indicator kriging. This work presents a novel approach to comparing various imputation techniques for reconstructing threshold overruns and modelling trends in exceedance rates. Moving beyond conventional error metrics, the evaluation is grounded in distributional similarity and monotonic dependence using Hellinger and Kullback-Leibler distances and generalised Lorenz curves. Based on the comparative analysis, indicator kriging was identified as the most robust approach and was subsequently adopted to parameterise the log-linear trend in the proportion of monitoring stations expected to exceed the concentration threshold. This study provides a methodological framework for addressing extreme missingness in environmental monitoring networks, offering actionable insights for EU Member States reporting under the Nitrates Directive.
Determinants of farmers’ intention to invest in integrated on-farm energy production in four European countries

This paper explores farmers’ interest in on-farm renewable energy generation across Belgium, Denmark, Iceland and Poland. We focus on adoption patterns, drivers, barriers and training needs. Drawing on a literature review and a cross-country farmer survey, the study examined existing energy generation practices, availability of surplus feedstocks and intentions to invest in new renewable energy enterprises. While 54% of respondents had some form of energy generation, predominantly solar panels on buildings, only a few used more complex systems such as biogas or biomass. Logistic regression analysis identified two statistically significant predictors of near-term investment interest: presence of a farm successor and establishment costs. Farmers favoured low-barrier technologies, and financial returns and business sustainability were key motivations. High capital costs of installation and concerns over long-term land use change were major deterrents. As a result, it is unsurprising that farmers saw the need for financial incentives, such as grants and low-interest loans. In-person workshops were preferred for training. The findings suggest that, rather than viewing adoption as a single event, policymakers and advisory services should encourage continuous expansion and diversification, focusing on reducing investment barriers and making energy generation density a policy metric.
