Response of sandy soil structure to long-term farmyard manure rates: The role of organic carbon and glomalin
(Elsevier, 2026) Juriga, Martin; Šimanský, Vladimír; Jonczak, Jerzy; Chojnacka, Aleksandra; Wójcik-Gront, Elżbieta; Pikuła, Dorota
Long‑term changes in soil structure under farmyard manure (FYM) application remain insufficiently understood in sandy soils, which are naturally poor in organic matter and highly susceptible to degradation. This study evaluates the century‑scale effects of gradually increasing annual FYM rates (0, 20, 40, 60 Mg ha⁻¹ yr⁻¹) in a 96‑year field experiment established on a Planosol in Skierniewice, central Poland. The results showed that increasing FYM inputs caused pronounced accumulation of soil organic matter. Total organic carbon (TOC) rose from 5.06% in the control to 7.53%, 11.18%, and 14.43% under 20, 40, and 60 Mg ha⁻¹, respectively (up to +185%). Total nitrogen (TN) increased from 0.45% to 1.29%, while total glomalin-related soil protein (T‑GRSP) rose by 34–77% relative to the unfertilized soil. Bulk density declined significantly only at the highest rate (from 1.69 to 1.52 g cm⁻³). Structural responses were nonlinear: mean weight diameter (MWD) increased sharply already at 20 Mg ha⁻¹(from 0.62 to 0.87 mm), and vulnerability coefficient (Kv) rose from 0.73 to 2.50, indicating higher aggregate vulnerability at 20 Mg ha⁻¹, but higher FYM rates did not further change vulnerability. Individual size-fractions of water-stable macro-aggregates (WSAma) 5–3 mm and 3–2 mm increased significantly under 20 Mg ha⁻¹, indicating an early saturation threshold. PCA confirmed that TOC, TN, and T‑GRSP are the dominant drivers of soil property changes. Overall, the greatest soil structural change occurred between the control and 20 Mg ha⁻¹ FYM. This study evaluated soil-level endpoint responses; crop productivity, crop-rotation performance, and environmental impacts were not measured and therefore cannot be inferred from the present dataset.

(Springer, 2026) Aboukhalid, Kaoutar; Machon, Nathalie; Lambourdière, Josie; Bakha, Mohamed; Neffa, Mounsef; Korbecka-Glinka, Grażyna; Khiraoui, Abdelkarim; Choudhary, Ravish; Lamiri, Abdeslam; Al Faiz, Chaouki
Oregano is a highly valued aromatic and medicinal herb in the Mediterranean, appreciated for its ecological, medical, and culinary properties. This paper aims to explore genetic variation and population structure within O. elongatum and O. grosii populations across their natural range in Morocco by analyzing 13 microsatellites (SSRs). Despite the restricted habitat of O. elongatum, the level of genetic diversity in this species is rather high (Ho = 0.455; He = 0.429); however, O. grosii possesses a reduced level of genetic diversity (Ho = 0.285; He = 0.291) while demonstrating more genetic differentiation between populations. Principal Coordinates Analysis and STRUCTURE analysis revealed four clusters that largely reflected the geographic origin of these plants and clearly separated the two taxa. These results indicate strong genetic differentiation and distinct population structures, supporting their differentiation as separate genetic entities. However, further integrative studies combining genomic and morphological data are needed to confirm their taxonomic status. No significant relationship between genetic and geographic distances was detected, indicating the absence of isolation by distance in the species studied. These findings underscore the necessity of developing species-specific or unit-based approaches to their conservation. Overall, this study illustrates how genetic data can inform conservation planning for rare endemic plants in ecologically sensitive regions, providing a model applicable to other Mediterranean mountain ecosystems facing climate and land-use pressures.
Development of Gluten-Free Corn Snacks Enriched with White Mulberry Fruit: Polyphenolic Composition, Antioxidant Activity and In Vitro Gastrointestinal Stability of Phenolic Compounds
(MDPI, 2026) Kasprzak-Drozd, Kamila; Ziółkiewicz, Agnieszka; Wojtunik-Kulesza, Karolina; Gancarz, Marek; Kowalska, Iwona; Misiurek, Justyna; Wójciak, Magdalena; Sowa, Ireneusz; Oniszczuk, Tomasz; Combrzyński, Maciej; Oniszczuk, Anna
The aim of this study was to evaluate the effect of adding white mulberry (Morus alba L.) fruit to extruded corn snacks on their polyphenol profile, antioxidant properties, acetylcholinesterase (AChE) inhibitory activity and the preservation of phenolic compounds in an in vitro digestion model. Mixtures of corn grits with 0, 10, 15 and 20% dried mulberry fruit were extruded at temperatures of 100, 120 and 140 ◦C, and then the total polyphenol content (TPC) and antioxidant activity (IC50 for DPPH) were determined. For selected samples (0%, 140—3E; 15% mulberry, 140—9E; mulberry—13E), further antioxidant tests (FRAP, CUPRAC, Fe2+ chelation) were performed, the phenolic compound profile (UHPLC) and AChE inhibition were assessed, and a two-step in vitro digestion was conducted. The addition of mulberry significantly increased TPC- and free-radical-scavenging capacity compared to the control sample, with snacks containing 15% mulberry extruded at 140 ◦C showing approximately a 3.5-fold higher TPC than the control, while dried mulberry fruit itself exhibited about a five-fold higher TPC than this enriched snack. Among the snacks, the most favorable DPPH-radical-scavenging effect was obtained for the variant with 20% mulberry at 120 ◦C (IC50 = 0.176 mg/mL), whereas the mulberry fruit extract reached an IC50 of 0.0926 mg/mL. In a two-step in vitro digestion model, the mulberry-enriched snack with 15% fruit retained 69.3% of its initial TPC after the gastric phase and 33.3% after the intestinal phase, compared with 55.0% and 20.0%, respectively, for the control snack, confirming a partial but meaningful preservation of phenolic compounds under simulated gastrointestinal conditions. UHPLC analysis confirmed that mulberry and the enriched snacks are a rich source of chlorogenic acids and their isomers, as well as quercetin and kaempferol glycosides, which largely survived the two-step in vitro digestion, despite an observed decrease in TPC after the gastric stage and a further reduction after the intestinal stage. At the same time, mulberry extract and mulberry-enriched snacks exhibited high antioxidant activity in all tests conducted and in vitro AChE inhibitory activity, suggesting that Morus alba L. fruit has the potential to be used as a natural functional ingredient in the production of gluten-free snacks with antioxidant and potentially neuroprotective properties.
Persistence, Resilience, and Economic Outcomes of CAP-Supported Organic Farms: Evidence from Poland
(MDPI, 2026) Zieliński, Marek; Gołębiewska, Barbara; Jadczyszyn, Jan; Pimenow, Sergiusz; Sobierajewska, Jolanta; Adamski, Marcin; Tyburski, Józef
Organic farming in the European Union is strongly shaped by Common Agricultural Policy (CAP) support, yet participation durability remains less examined than supported organic area or organic–conventional comparisons. This study assesses whether the length of participation in CAP-supported organic farming is associated with the organizational, production, and economic outcomes of organic farms in Poland. It applies a two-level approach: CAP support trajectories based on ARMA data for 2008–2025 and organic production duration based on Polish FSDN data for 2008–2022. A comparative analysis was conducted of the characteristics of the potential, organization, and economic situation of farms with varying levels of persistence within the organic farming support system. The frequent variation in the results obtained indicates the distinct characteristics of these groups of farms. The results show that organic farming in Poland is highly CAP-dependent and follows an unstable trajectory, with expansion up to 2012–2013, subsequent decline, and renewed growth after 2019. Longer participation is associated with differences in land resources, supported organic UAA, ANCs conditions, production organization, and livestock presence, indicating both adaptation and structural selectivity. FSDN data show that fully organic farms have lower land and labor productivity than conventional farms, but persistent fully organic farms achieve similar income per hectare when subsidies are included; without subsidies, their income remains much weaker. The findings indicate that the evaluation of organic farming support should move beyond beneficiary counts and certified organic area to include participation durability, production-system coherence, economic viability, and territorial embeddedness. More differentiated instruments are needed to strengthen durable, knowledge-intensive, and territorially embedded organic farming systems.
The core microbiome of fluvisols from the Vistula River Valley: relationships between bacteria and basic soil properties
(TÜBİTAK (Scientific and Technological Research Council of Turkey / Turecka Rada Badań Naukowych i Technologicznych), 2026) Furtak, Karolina; Marzec-Grządziel, Anna; Grządziel, Jarosław; Niedźwiecki, Jacek
Fluvisols develop in river valleys through the accumulation of alluvial sediments. They are characterised by high fertility and are extensively used for agriculture. This study aimed to identify the core microbiome of fluvisols in the Vistula Valley and to examine its relationship with the basic physicochemical properties of the soils. Six types of fluvisol (very light, light, medium, and heavy) from four locations in Lublin province were analysed, with samples collected in 2018 and 2022. The microbiome structure was determined by sequencing the V3–V4 region of the 16S rRNA gene and was compared with soil parameters such as pH, electrical conductivity, organic matter, nitrogen, carbon, and metal contents. A core microbiome, dominated by Acidobacteria_Gp6 (ASV_018) and Rhizobiales (ASV_001), was identified in all samples. Together with Actinobacteria and Proteobacteria, these taxa perform key ecological functions, including nutrient cycling, supporting plant growth, and maintaining soil ecosystem stability. The results confirm the hypothesis that specific bacterial groups within the core fluvisol microbiome contribute to its high quality and agricultural suitability. The data provide a basis for further research into the functional role of the floodplain soil microbiome and its resilience to periodic flooding.
