Soybean (Glycine max L.) is one of the most sought-after legumes on the global market due to its high demand in the feed, food, and industrial sectors. Climate change necessitates the implementation of technological innovations to enhance plant resistance to adverse growing conditions. The aim of this study was to investigate the effect of pre-sowing seed treatment of soybean with the bacterial preparation Profix, the phytohormone based preparation Violar, as well as their combined application through seed inoculation and crop spraying during the bud formation–bloom phase, on the development and productivity of soybeans under an organic farming. To examine the dynamics of leaf surface area, photosynthetic pigments, malondialdehyde and proline levels, and their relationship with yield, the ANOVA-Tukey test and principal component analysis were employed. The field experimental results showed that pre-sowing seeds treatment with the Profix inoculant, the phytohormonal preparation Violar, and their combined application contributes to an increase in leaf surface area, an enhancement in the content of photosynthetic pigments, a reduction in malondialdehyde levels, and an increase in proline content in soybean plant. These physiological improvements ultimately led to average soybean yield increases of 12.3%, 19.6%, and 29.2%, respectively, despite adverse weather conditions 2024. These results demonstrate the effectiveness of integrating bacterial and phytohormonal seed treatments as a sustainable and innovative approach to enhancing soybean productivity under organic farming conditions.

Landfills are widely utilised for waste disposal due to their economic advantages and ease of implementation compared to alternative methods. However, landfills exert significant environmental and health impacts on adjacent agricultural land. Accumulation of heavy metals in soil is a risk to ecological and food safety. Methodological approaches to assess and mitigate the impact of landfills on agricultural land are essential for ensuring sustainable land use practices and safeguarding human health. In this study, landfills were assessed at the local level, and the hazard level was classified according to it. A set of priority measures for restoring technogenic disturbed areas and minimising their impact on agricultural land was determined. The need to select a set of innovative, ecologically oriented methods for remediation of landfills, depending on the type and degree of soil contamination, was identified in context of ensuring environmental and food security.
Assessment of the soil microbial community under energy crops (Panicum virgatum L. and Miscanthus giganteus): a case study from Ukraine

Bioenergy crops are a promising alternative for energy production. They can be grown on inaccessible, degraded, marginal land that is not economically viable for traditional agriculture. At the same time, a broader evaluation of the environmental and ecological impact of energy crop cultivation on land is needed. There are still knowledge gaps regarding the mechanisms underlying soil carbon accumulation, especially concerning the involvement of the soil microbiome in facilitating these processes during energy crop cultivation. The present study determined the main ecotrophic and taxonomic groups of soil microbial communities and the direction of soil microbiological processes under Panicum virgatum L. and Miscanthus giganteus growth. Research results showed an initial impact of energy crop growth on soil microbial communities in the soil-climatic conditions of Ukrainian forest-steppe zones. Soils under energy crops are characterized by the highest abundances of the investigated ecological and trophic microbial groups (by 1.2-3 times) compared to control (soil under grassland). The coefficients of microbiological processes determine the high potential for increasing soil fertility under energy crop cultivation. Statistical analysis of the results confirmed a medium and strong correlation between soil microbiological parameters and soil organic carbon content during energy crop growth. Therefore, energy crops can act as ecosystem engineers, improving soil biological and chemical properties and supporting soil ecosystem sustainability.

Biological mechanisms of invasiveness of Ambrosia artemisiifolia L. and innovative control approaches
(2025-12-03) Оніпко, Валентина Володимирівна; Onipko, V. V.; Поспєлов, Сергій Вікторович; Pospelov, S. V.; Поспєлова, Ганна Дмитрівна; Pospielova, G. D.; Pospelova, H; Коваленко, Нінель Павлівна; Kovalenko, N. P.
The purpose of the review was to summarize current scientific approaches to studying the biological mechanisms of invasiveness of Ambrosia artemisiifolia L., to identify ecological and agroeconomic risks associated with its spread, and to analyze innovative strategies for controlling this dangerous weed. Ambrosia artemisiifolia L. is one of the most aggressive invasive species of the Asteraceae family, posing a significant threat to agroecosystems, natural biodiversity, and human health. Its spread under conditions of trade globalization and climate change has reached a large scale, emphasizing the need for interdisciplinary research on the bioecological characteristics of this species and the development of comprehensive control strategies. The high invasive potential of A. artemisiifolia is determined by a complex of adaptive traits: rapid initial growth, tolerance to various soil types and climatic conditions, a powerful root system, cross-pollination, and pronounced seed heteromorphism. These features ensure the formation of persistent soil “seed banks” that support long-term population recovery even after mechanical or agronomic interventions. In addition, the considerable genetic variability of the species promotes local adaptation to changing climatic and anthropogenic factors, complicating control efforts across regions. It was emphasized that the expansion of ragweed in Europe and Asia leads to reduced crop yields, displacement of native species, and ecosystem degradation. Losses in the agricultural sector are associated with both direct decreases in the productivity of maize, sunflower, soybean, and other crops, and with increasing costs of herbicide application. However, chemical control is complicated by the development of resistance to major groups of herbicides. This underlines the relevance of integrated weed management approaches, that combine agronomic practices (crop rotation, optimization of sowing density, cultivation of competitive crops), biological control (entomophages, phytopathogens, microbial preparations), chemical methods, and environmentally safe technologies. A promising direction is the use of modern geographic information systems, remote sensing methods, and mathematical modeling to monitor the spread of A. artemisiifolia and predict its invasion dynamics under climate change. Such an approach makes it possible to identify priority control areas and effectively allocate resources. Further research should focus on improving adaptive integrated management systems for ragweed populations, assessing the long-term consequences of its invasion for biodiversity and human health, and developing ecologically oriented models of sustainable land use.
Comparative characteristics of morphometric indicators of quarantine species of the genus Cuscuta (Cuscuta L.) growing in Ukraine
(2025-12-08) Коваленко, Нінель Павлівна; Kovalenko, N. P.; Поспєлова, Ганна Дмитрівна; Pospielova, G. D.; Самородов, Віктор Миколайович; Samorodov, V. M.; Поспєлов, Сергій Вікторович; Pospelov, S. V.; Pospielov, S.; Оніпко, Валентина Володимирівна; Onipko, V. V.
A review is devoted to the comparative characteristics of the morphometric and biological features of doddlers in Ukraine based on a scientific source base. The systematic position of the common quarantine parasitic plants of the genus Cuscuta L. (dodder), commonly found in Ukraine, is presented. A morphometric analysis of 15 species is provided, highlighting differences in stem diameter, length, and color, features of the flower structure, types of inflorescences, and fruit shape. The literature data indicate a high degree of similarity among Cuscuta species prevalent in our country, which significantly complicates their identification in natural environments and agrocenoses, and is insufficient for clear and, more importantly, unmistakable identification by professionals in applied branches of the agricultural industry. Knowledge of the biological characteristics of Cuscuta species is important for understanding their spread and high naturalization potential. Currently, this information is quite fragmented and insufficiently studied. Information is presented regarding the most studied species, namely: C. campestris Yunck., C. trifolii Bab., C. europaea L., C. epilinum Weihe, C. Lemanniana Bge., C. lupuliformis Krock. and C. epithymym L. An important factor in the formation of the infectious background in agrocenoses and natural environments is the seed viability period. It has been established that the longest period of preservation of its viability is observed in C. trifolii Bab. (10-12 years); up to 6 years in C. campestris Yunck, C. europaea L., and C. Lemanniana Bge. The shortest viability period is up to one year (in the soil) in C. epilinum Weihe. However, there are reports about the possibility of preserving seed viability for up to 25–30 years under conditions unfavorable for its germination. In our opinion, this is due to such a phenomenon as "hardseededness". The formation of the seed bank in the soil is also influenced by the fertility of the species. Among the Cuscuta species growing in Ukraine, this indicator has been established only for seven species: C. campestris Yunck., C. trifolii Bab., C. europaea L., C epilinum Weihe, C. Lemanniana Bge., C. lupuliformis Krock., and C. epithymym L. The largest number of seeds per plant is produced by C. Lemanniana Bge. (up to 100.000) and C. campestris Yunck. (up to 114.000). The period of emergence of seedlings has been found to be March-May. It depends on the soil temperature and the depth of seed placement. It has been determined that at a soil temperature of 16–25 ⁰С, mass seed germination occurs in May-June. The flowering period is extended and lasts from June to August.

(2024) Pospielov, S. V.; Mishchenko, O. V.; Onipko, V. V.; Pospielova, G. D.; Поспєлов, Сергій Вікторович; Міщенко, Олег Вікторович; Оніпко, Валентина Володимирівна; Поспєлова, Ганна Дмитрівна
The paper presents experimental data on the effect of echinacea extracts on the sowing qualities of medicinal herbs. The biological activity of extracts obtained from the areal part (EAP) and rhizomes with roots (ERS) of pale echinacea was investigated. The object of study was the sowing quality of the seeds of such medicinal plants as blue cornflower (Centaurea cyanus L.), purple echinacea (Echinacea purpurea (L. Moench.), pale echinacea (Echinacea pallida (Nutt.) Nutt.), St. John's wort (Hypericum perforatum L.), forest mallow (Malva sylvestris L.), which are of industrial importance for medicinal plants. The seeds were soaked in 0.01%-0.0001% solutions of extracts, under the control they were treated with water, after that they were germinated in Petri dishes by generally accepted methods according to the standards. The best results were obtained in mallow seed extracts. The solution of EAP at a concentration of 0.001% increased the energy of germination by 19.2% compared to the control, and when using ERS in all concentrations, a positive effect was obtained (by 18.2 %-23.6% to the control). Germination of variants treated with EAP solutions increased by 1.12-1.21 times, and ERS – by 1.09-1.21 times. Treatment of Echinacea purple seeds with EAP solutions was not effective, but rhizome extract treatment with roots had a positive effect on both germination energy and germination resulting 12.0%-17.3% and 8.3%-9.5% compared to the control, respectively. Similar regularities were observed in variants with the treatment of Echinacea seeds with extracts in different concentrations. The action of EAP solutions did not statistically exceed the control, but when using ERS, the results reliably exceeded the control by 10.8%-13.8% (germination energy) and by 11.0%- 17.8% (germination). Treatment of St. John's wort and cornflower seeds with extracts did not lead to changes in seed quality indicators. A general trend of greater activity of extracts in concentrations of 0.01%-0.001% was observed.

Soil organic matter (SOM) is one of the primary indicators of soil quality, which plays an important role in enhancing a range of soil physical, chemical and biological functions in the agricultural ecosystem. Switchgrass cultivation for bioenergy has the potential to improve and stabilize soil properties on marginal land over the years. The research was aimed to evaluate the dynamics of SOM in different types of switchgrass cropping systems and the influence of SOM on switchgrass productivity. The experiment was performed on a marginal land in the central part of the forest-steppe zone of Ukraine. The switchgrass (Panicum virgatum L.) cultivar ‘Cave-in-Rock’ was used. The experiment included two factors. Factor A – type of cropping: 1) sole crops of switchgrass (Sw) – control; 2) strip intercropping of switchgrass and lupine (Sw + strip); 3) mixed intercropping of switchgrass and lupine (Sw + mix). Factor B – years of switchgrass cultivation (2010–2016). It was demonstrated that perennial switchgrass cultivation has the potential to increase SOM content. SOM content in Sw + strip crops increased by 0.12%, in Sw + mix – by 0.09% and in Sw – by 0.07%. The highest switchgrass productivity was formed in Sw + strip (from 1.11 to 1.53 kg m-2) and in Sw + mix (from 1.12 to 1.45 kg m-2) crops, the lowest – in Sw (from 0.85 to 1.34 kg m-2) crop. The maximum switchgrass productivity was observed for 5–7 years of cultivation. The highest height of plants and number of shoots of switchgrass were in Sw + strip crops, and significantly less in the other treatments. The results of the experiment showed a great increase of switchgrass productivity and SOM content in switchgrass crops and confirmed that switchgrass can be a sustainable energy crop.

The search for novel substances that promote the establishment of a microbial community and facilitate optimal humification processes while increasing soil organic matter content offers an opportunity for land restoration. The objective of study was to determine the abundance of ecological and trophic groups of soil microorganisms and the intensity of microbiological processes when subjected to probiotic treatment at various concentrations and doses in typical black soil. The eco-trophic groups of soil microorganisms were identified by inoculating dilutions of soil suspensions onto selective nutrient media. The direction and intensity of soil microbiological processes were assessed using the mineralization-immobilization, oligotrophy, and pedotrophy indexes. The results demonstrate that probiotics has a positive impact on the microbiological activity of the soil, leading to an increase in the number of ecological and trophic groups of soil microorganisms during both spring and autumn seasons. Notably, a significant effect on the soil microorganism conditions was observed after 30 days of probiotic treatment. Probiotics exhibit a favorable influence on microbiological processes within the soil, fostering conducive conditions for the development of soil microorganisms and the formation of humus. The most effective concentration of probiotics for promoting the functionality of microbial communities in black soils is determined to be 10%, accompanied by a dose of 100 l ha-1. Consequently, the application of probiotic treatment at a concentration of 10% and a dose of 100 l/ha-1 holds the potential to enhance the biological state of the soil, restore soil microbial diversity, and serve as an environmentally safe fertilizer.

The problem of soil contamination is relevant today. Soil contamination is generally associated with intensive industrial activities, inadequate waste management, mining, military activities, or accidents. Pollutants (e.g. heavy metals) are accumulating in soil and have major indirect impacts on biodiversity, quality of groundwater resources, and food safety. Soil contamination of agricultural land is a particular threat. Due to the military action and other conditions, the numbers of sites where potentially polluting activities have taken place are increasing in Ukraine. The cultivation of agricultural crops on soils with a medium or high level of toxicity is only possible after the re mediation of this area. The use of biological methods to intensify soil remediation processes, thereby reducing the additional burden on the environment, is becoming more widespread. The application of probiotics is an innova tive and ecological method for the restoration of contaminated soils. This will enable to improve the conceptual approaches to the implementation of an ecologically safe model for the restoration of contaminated land under the conditions of military action in Ukraine. The aim of the research was to assess the phytotoxic effect of soil con taminated with heavy metals and petroleum products before and after probiotic application. The seedling method was used to determine the remediation potential of contaminated soils. An express test of Triticum aestivum was used to determine soil phytotoxicity. The research results show the negative impact of soil contamination with heavy metals and petroleum products on the biometric indices of Triticum aestivum plants and positive dynamics of biometric indices of Triticum aestivum in variants after probiotic treatment (86–92% compared to the control). The obtained data show that a significant phytotoxic effect is observed by all biometric indices of Triticum aesti vum in all studied variants. The highest phytotoxic effect (33.56–42.70%) was observed in variants with combined contamination (PP+Zn+Pb). The results of probiotic application show a phytotoxic effect of less than 20% by all biometric indices of Triticum aestivum for all studied variants. Therefore, the results of the research can be used to develop recommendations for the remediation of land contaminated by military actions in Ukraine and the creation of sustainable agroecosystems.

Nanoparticles of iron/cobalt and iron/manganese oxides in the form of stable suspensions are used in the development and manufacture of nanotracers, which are used to check the mixing processes of animal feeds, which are in both solid and liquid states, the coding of liquid additives and the efficiency of their uniform distribution in prepared premixes and compound feed.
Formation of pale purple coneflower (Echinacea pallida (Nutt.) Nutt.) seed productivity in the conditions of the Left-Bank Forest-Steppe of Ukraine
(2025-12-08) Поспєлов, Сергій Вікторович; Pospelov, S. V.; Поспєлова, Ганна Дмитрівна; Pospielova, G. D.; Zezekalo, Ye.; Оніпко, Валентина Володимирівна; Onipko, V. V.; Manachynskyi, O.
The study results of seed productivity of pale purple coneflower (Echinacea pallida (Nutt.) Nutt.), a promising medicinal and honey crop are presented. The research was conducted in the conditions of production plantations of Poltava region. It was established that at the early stages of ontogenesis, pale purple coneflower developed slowly: the first sprouts appeared 11–15 days after sowing and this period extended to 20–25 days. The cotyledon leaf phase lasted about for 7–9 days, and the first true leaf was formed during 25–32 days. The above-ground part and root system grew slowly in the first two months, their development accelerated from July. By the end of the vegetation, the plant formed a rosette of leaves and a fleshy vertically thickened rhizome. The generative period of pale purple coneflower began from the second year of growing season. Flowering lasted on the average for 46–52 days, starting in June. Plants reached a height of 85 cm, forming from 1 to 9 generative stems (on the average – 5.4). The average number of seeds per plant made 2770 pieces, and thousand-seed weight varied within 2.3–3.55 g. The morphometric study of the parameters of different orders’ inflorescences on the shoot shows that the anthodia of the first-fourth orders were characterized by the largest diameter (3.02–3.60 cm) and the height of the inflorescences (2.443.25 cm). The first three inflorescences provided 68 % of the total seeds’ weight from the plant, which indicates their highest productivity and value. It is emphasized that the sowing qualities of pale purple coneflower seeds are limited by a long period of organic dormancy. Laboratory germination of freshly harvested seeds from inflorescences of the first order did not exceed 60%, but of inflorescences of the second and third orders was 75–78 %. Infectious structures of five fungi genera (Alternaria, Cladosporium, Fusarium, Mucor, Stachybotrys) were found on the achenia. To increase germination, it is recommended to conduct stratification at a temperature of +4–5°C for at least 60 days. It was concluded that seed crops of pale purple coneflower can be used more rationally by harvesting inflorescences of the fourth and higher orders for pharmaceutical needs. Taking into account the biological characteristics of the crop will contribute to increasing the yield and ensuring the stable cultivation of this promising plant.
