“…In particular, agricultural land is used for other purposes, there is a problem of land degradation, and the lack of a full-scale land survey results in the absence of up-to-date statistics on the quantity and quality of land resources. The outbreak of the Russian-Ukrainian war in 2022 also affected agricultural land in Ukraine, and this impact cannot be assessed at this time, as the country is still at war [1]. China, which, like Ukraine, is a developing country, has similar problems in the field of land resources.…”

Agriculture has always been central to China's cultural and economic development. The traditional calendar used in China to this day tells villagers the best time to sow and harvest, further confirming the importance of agriculture in everyday life. Land has always been the backbone of the agricultural sector, which in turn is the cornerstone of China's economy. Over the years, they have ensured national food security and provided livelihoods for large populations. Although the total amount of agricultural land in China is the third largest in the world, for a large area of land, only 0.106 hectares per capita is accounted for, which is far below the world average. Given the pressures of shrinking agricultural land due to economic development, rapid population growth, and urban growth, the Chinese government has developed a series of measures to protect agricultural land and ensure food security. This article is aimed at a detailed analysis of the evolution of agricultural land protection policy in China, an attempt to analyze the reasons for policy change, the measures introduced and their effectiveness. It will also provide experience and inspiration for solving issues related to land resources in Ukraine and can become the basis for cooperation between China and Ukraine in the field of agriculture to jointly address the global challenges of food security.

“…It has been established that the edaphic conditions and factors that determine the soil fertility (SOC, C/N, NPK content in the soil) correlate with the structure of the microbial group, the dependence of the number and diversity of microbiota on the environmental and human factors that determine the stability of agricultural soil (Symochko et al, 2019). Analysis of the taxonomic structure of microbiocenoses of the studied soils (Fig.…”

Soil microbial communities play an important role in ecosystems functioning and are on the field scale essential for plant nutrition and health. On a larger scale, they contribute to global element cycling. Furthermore, they are involved in the turnover processes of organic matter, the breakdown of xenobiotics and the formation of soil aggregates. An ecological state of soils depends on the structure and activity of soil microorganisms. The results of soil monitoring in various ecosystems in different climatic zones of Ukraine showed a clear trend for the correlation between the agroecological conditions and activity of microbiocenosis. The most significant influence of agricultural activity on the soil microbiota can be observed on the poorly soddy-podzolic and gray forest soils, where the crop cultivation without fertilization resulted in a decrease in the total count of microorganisms by 2.2-4.5 times. Application of agricultural measures aimed at achieving maximum productivity, specifically the combination of mineral, organic and biological fertilizers, contributes to an average 1.3-4.1 times increase in the total count of microorganisms in the soil, compared with non-fertilized variants. Soils with low content of organic matter and acidic medium, soddy-podzolic and gray forest soils were characterized by a high number of micromycetes, 136-185×103 CFU·g-1 soil, and a relatively low number of eutrophic and nitrogen-fixing microorganisms. The soil of natural ecosystems is characterized by a high total count of the microorganisms with a balanced structure of various ecological-trophic groups and balanced processes of mineralization-immobilization, organic matter decomposition, and humus accumulation.

Terrestrial ecosystems play a crucial role in the formation of soil resistome and the spread of antibiotic-resistant bacteria. Comprehensive studies of soil microbial communities, their structure, integrity, and level of antibiotic resistance (AR) in various terrestrial ecosystems were conducted. In total, 389 strains of dominant bacteria were isolated from the studied ecosystems, 57 of which were resistant to antibiotics, with levels of antibiotic resistance exceeding 70%. The soil microbiome of primeval forests was characterized by a low content of bacteria resistant to antibiotics; only two species, Bacillus cereus and Pantoea agglomerans, showed a high resistance to antibiotics. In the soil of agroecosystems of medicinal plants, among 106 strains of bacteria, a high level of resistance to antibiotics was found in 13 species. It was established that the number of antibiotic-resistant bacteria is highest in the soil of agroecosystems contaminated by enrofloxacin. Among 190 tested bacterial strains, 42 (22%) were characterized by a high level of antibiotic resistance. Therefore, the soil ecosystem is a key link in the formation and spread of antibiotic-resistant bacteria, which is a potential danger to humans. To reduce the risk of AR for humans, it is necessary to take appropriate measures to manage the soil microbiome and avoid soil contamination with antibiotics.
