Effect of Paulownia and Buckwheat Intercropping on Soil Microbial Biodiversity, Dehydrogenase Activity, and Glomalin-Related Soil Protein
(MDPI, 2025) Woźniak, Małgorzata; Liszewski, Marek; Jama-Rodzeńska, Anna; Gębarowska, Elżbieta; Siebielec, Sylwia; Kaczmarek, Agata; Gałka, Bernard; Zalewski, Dariusz; Bąbelewski, Przemysław
Intercropping of trees and classical crops has been proposed as a practice to help adapt to climate change and protect soil against erosion. However, the effects of intercropping on soil biology are not sufficiently quantified. Therefore, the aim of this study was to evaluate microbiological changes in the soil resulting from the intercropping of Paulownia and buckwheat. A field experiment, involving an intercropping and control no-tree variant, was conducted from 2019 to 2022 with a plot size of 30 m2. Buckwheat rhizosphere soil samples were collected twice in both 2021 and 2022 in order to evaluate the effects of intercropping on a range of parameters describing soil microbiome status: abundance of microorganisms, bacterial and fungal community structure (using Illumina MiSeq sequencing), dehydrogenases (DHA) activity, and total glomalin-related soil proteins (T-GRSP). In addition, the colonisation of buckwheat roots by fungi, yield, and biometric traits of the plant were determined. Next-generation sequencing showed that Actinobacteria, Proteobacteria, and Acidobacteria were dominant in the microbiome of every variant of the experiment, regardless of the crop. In contrast, the mycobiome was dominated by fungi classified as Ascomycota and Mortierellomycota. This observation corresponded to an increase in buckwheat yield in intercropped plots. Biometric traits, namely buck wheat yield and total kernel weight per plant, showed higher values when buckwheat was intercropped with Paulownia compared to the control. DHA activity was stimulated by intercropping at the first sampling date, whereas glomalin concentration and abundance of microorganisms were not dependent on the cropping systems tested. This study shows that tree-based intercropping (TBI) systems promote a more diverse soil microbial community and function than conventional agriculture. Our results also suggest that TBI positively impacts buckwheat biometric traits, supporting its implementation in rural landscapes. The yield under intercropping cultivation amounted to 0.65 t ha−1, while in control sites it was 0.53 t ha−1. The total abundance of bacteria under intercropping cultivation was higher compared to monoculture in 2021 at the first term of sampling (4.3 × 10 4) and in 2022 in the second term of soil sampling (4.6 × 10 4).
Changes in soil organic carbon stocks and chemical properties in organogenic soils under long-term agricultural use in Central Europe, Poland
(John Wiley & Sons Ltd, 2025) Zając, Ewelina; Smreczak, Bożena; Ukalska-Jaruga, Aleksandra; Skalski, Tomasz; Oleszczuk, Ryszard; Scharenbroch, Bryant C.
Organic soils, particularly peatlands, are important carbon sinks. In Europe, almost half of its area has been drained and is primarily used for agriculture as grasslands. In Poland, 86% of the drained peatland area causes problems with high carbon dioxide emissions due to organic matter oxidation. The aim of the study was to analyze changes in organic soils between 1975 and 2017 using data from 476 reference soil profiles. The results showed a significant decrease in organic soils (≥12% SOC) from 62% to 35%, and an increase in organo-mineral (6.0-12.0% SOC) and non-humose mineral soils (≤1.75% SOC) by a similar percentage. The depth of SOC rich layers also decreased significantly, with deep soils (>100 cm) dropping from 20% to 5% and shallow soils (21-50 cm) increasing from 24% to 58%. The average SOC stock loss was almost 273 Mg C·ha -1 (from 500.42 Mg C·ha -1 to 228.04 Mg C·ha -1), with the median being four times lower. A decrease in SOC stock was observed in 64% of sites, while an increase was seen in 36%. The most significant decrease in SOC stock, by 64.67% compared to 1975, occurred in organic soils (from 762.19 Mg C·ha -1 to 269.26 Mg C·ha -1). There was an increase in SOC stock in organo-mineral, humose, and non-humose mineral soils, although it was not statistically significant. Moreover, the results indicated that continuous grassland use on organic soils does not offset carbon losses from organic matter oxidation due to drainage.
The Influence of Fusarium culmorum on the Technological Value of Winter Wheat Cultivars

The research hypothesis assumes that Fusarium culmorum infection affects the baking value of wheat. The aim of the research was to determine the effect of the cultivar on the rheological properties of wheat dough in response to Fusarium culmorum infection of wheat. A two-factor experiment conducted during the 2018–2020 growing seasons in Osiny, Poland, was set up using the completely randomized block design with three replications. The first factor was winter wheat cultivars (six cultivars), while the second factor was inoculation (two levels—Fusarium culmorum and distilled water—control). The immunoenzymatic ELISA method was used to determine the content of deoxynivalenol (DON) in grain. The DON content in the grain varied between cultivars. Fusarium culmorum inoculation resulted in an increase in protein, ash content, and flour water absorption, changes in dough rheological properties, and a decrease in the sedimentation index. Inoculation also caused negative changes in starch properties. The observed interaction between Fusarium culmorum inoculation and cultivars in shaping the qualitative parameters and rheological properties of the dough indicates that there are wheat cultivars less susceptible to Fusarium infection, which do not show any significant changes as a result of infection.
Biological Activity of Monoterpene-Based Scaffolds: A Natural Toolbox for Drug Discovery
(MDPI, 2025-03-27) Mołdoch, Jarosław; Agacka-Mołdoch, Monika; Jóźwiak, Grzegorz; Wojtunik-Kulesza, Karolina
One of the most common strategies used in drug design is the molecular scaffold approach, which combines traditional medicine based on natural active compounds derived from plants with modern synthetic drug development. Designing new compounds based on natural skeletons enables extensive modifications of both bioavailability and biological activity. An excellent example of a natural molecular scaffold is the monoterpenes group, which serves as a core structure for building more complex molecules by attaching various chemical groups. Their ability to interact with biological targets, combined with structural versatility, makes them promising molecular scaffolds in pharmaceutical research and green chemistry applications. This review paper focuses on selected monoterpenes (carvacrol, carvone, citral, menthol, menthone, β-pinene, thymol, and verbenone), which are frequently used as molecular scaffolds. The newly designed derivatives exhibit various biological activities, including anticancer, antibacterial, antiviral, neuroprotective, and many others.
Influence of Production Technology Intensity on the Yield and Amino Acid Profile of the Grain Protein of Different Sowing Oat (Avena sativa L.) Cultivars

The biological value of protein is mainly determined by its amino acid composition, and primarily depends on the optimal content of individual exogenous amino acids. The synthesis of these compounds in oat grain is influenced by genetic factors, habitat conditions and the agrotechnology used in cultivation. The aim of this study was to assess the influence of production technology (integrated, intensive) on the yield, content and amino acid profile of protein in the grain of hulled and naked oats. Field studies were conducted at the Agricultural Experimental Station Kępa—Pulawy, Osiny farm of IUNG—PIB (Poland) during two growing seasons (2019 and 2020). It was found that the total protein content of oat grain and its amino acid composition significantly depended on genotype and production technology. Naked oat grain was characterised by significantly higher protein content. The higher the intensity of production, the higher the content of total protein and exogenous and endogenous amino acids. Lysine was the amino acid that limited the biological value of protein in the grain of both oat cultivars. Its deficit was more frequent in grain from intensive production technology.
