“…In recent years, researchers from many countries have actively discussed a valuable new biological method for decontaminating polluted soil, which offers an alternative to conventional cleaning methods by harnessing the biological productivity of living organisms -bioremediation. Biological methods, particularly phytoremediation, help address two important issues: they are cost-effective and do not require the introduction of special reagents, solutions, or chemicals into the soil (thus avoiding additional pollutants) [16]. Recently, the use of plants, specifically phytoextractors, for ecosystem remediation has become more prevalent.…”

Significant environmental concerns are raised by heavy metal pollution in soils, particularly in areas like South Kazakhstan where hazardous materials have accumulated as a result of human activities including mining, industry, and agriculture. This paper presents theoretical and experimental findings regarding the phytoremediation potential of sowing peas (Pisum sativum) in the grey soils of South Kazakhstan. Special attention is paid to the determination of gross concentrations of various forms of copper, nickel, and cobalt in the initial and remediated soils. The methodology basis for the study were chemical phase analysis, atomic absorption spectrometry, and X-ray electron microscopy to assess heavy metal levels in soils and plant samples. It was established that in the arid climate of Southern Kazakhstan, the upper layers of the soil up to 40 cm contain the highest concentration of heavy metal ions. The findings of the study will allow predicting the effectiveness of phytoremediation measures. The study suggests that sowing peas have potential for phytoremediation due to their ability to accumulate heavy metals in their root systems and biomass. It highlights the potential of phytoextraction techniques, which involve growing metal-accumulating plants in polluted soils and processing the harvested biomass to recover absorbed metals.

“…Existing systems for fertilizing agricultural crops, as a rule, do not take into account environmental safety, since the required norms of mineral fertilizers are calculated according to the indicators of the removal of nutrients with the planned harvest, and the degree of use of active substances from fertilizers is quite low [17][18][19]. Most nitrogen fertilizers (>60%) used in rice cultivation technology are not completely absorbed by plants and remain in the soil in the form of ammonia, nitrates and nitrogen oxide, which leads to serious environmental problems [5,20,21]. That is why it is relevant to study the use of specific doses.…”

The purpose of this research is to study the effect of doses of nitrogen fertilizers and methods of their application on the development and yield of rice plants of the Syr Suluy variety in the Kyzylorda region of the Republic of Kazakhstan. To study the effectiveness of methods for applying nitrogen fertilizers, options for their fractional application were provided at a rate of 120 kg/ha and 150 kg/ha. The ammonium nitrogen in the soil and the intensity of dry matter accumulation during the vegetation phases were analysed. The biometric parameters of rice plants were also studied, and the yield was estimated. Increasing the dose of nitrogen fertilizers led to increased accumulation of dry matter throughout the various phases of the rice vegetation. The improvement of the nitrogen regime of the soil contributed to an increase in yield by 3.29 t/ha or 85% compared to the variant without nitrogen fertilization. It was also found that with fractional application and 150 kg/ha of nitrogen fertilizer, the maximum economic profitability of 78.1% was achieved. The obtained data, which indicates the benefits of fractional application and increased doses of nitrogen fertilizers, can be used to optimize agricultural technology by refining fertilization schedules and dosages. This will aid in achieving the maximum possible and economically viable yield of rice of the Syr Suluy cultivar, ultimately improving farming practices in the Kyzylorda region of the Republic of Kazakhstan.

Russia’s attack on Ukraine has caused widespread contamination of agricultural land, which is now an urgent environmental problem that is important for human health and sustainable development. In this regard, the purpose of this study was to analyse the impact of military operations in Ukraine on agricultural land. To fulfil this purpose, a study was conducted at the Educational and Research Centre of Mykolaiv National Agrarian University, which included data collection and analysis in different regions of Ukraine, including Dnipro, Mykolaiv, and Zaporizhzhia oblasts. It was found that in Dnipropetrovsk Oblast, soil contamination with lead exceeds the maximum permissible concentration (MPC) by 3 times and fluoride by 1.5 times; in Mykolaiv Oblast, the concentration of lead exceeds the MPC by 5 times, the content of zinc, copper, fluoride, and oil products by a quarter; and in Zaporizhzhia Oblast, the concentration of lead exceeds the MPC by 11.17 times, the content of zinc and fluoride is increased by half, petroleum products – by 35%, and phosphates – by 30%. Furthermore, the study confirmed the impact of military operations on the physical and chemical properties of soils, specifically, an increase in the acidity of the soil environment (pH) and the density of the topsoil. To reduce the impact of war on soil and the ecosystem, it is necessary to monitor and assess the effects of military operations, develop and implement environmentally friendly technologies, and restore and rehabilitate the affected areas. The findings of this study can be used to prepare recommendations for the authorities to minimise the environmental impact of military operations on soils
