Ecological and agrochemical assessment of the state of agricultural landscapes in Ivano-Frankivsk region

In the Western region of Ukraine, one of the main factors influencing the ecological safety of agricultural landscapes is anthropogenic pressure. Based on monitoring studies, ecological and agrochemical assessment of the state of agrolandscapes of IvanoFrankivsk region is conducted, in particular in residential areas. The state of soils, natural waters and crop production was studied by the method of route monitoring. Chemical and analytical studies were carried out using methods of chemical, physical and chemical analysis using modern methods of atomic absorption spectrophotometry, flame photometry, in accordance with the requirements of the quality management system, according to methods that meet the regulatory framework of Ukraine. It was determined that some of the studied soil samples had very low acidity and high content of biogenic elements (especially phosphorus and potassium) and pollutants. The quality of natural waters in some cases did not meet the regulatory requirements. This is due to both natural factors — features of the hydrological regime, and anthropogenic — violation of sanitary rules for the development of the territory, the introduction of high doses of mineral and organic fertilizers, noncompliance with manure storage technologies, the maintenance of domestic animals and poultry, and the disposal of livestock and household waste. Some samples of crop products did not meet sanitary and hygienic standards for the content of lead, cadmium, nickel, copper and iron. Studies indicate a significant impact of the anthropogenic factor on the change in the quality of soil, natural waters and crop production. Conducting an ecological and agrochemical assessment of the state of agricultural landscapes in the Western region, including residential areas and establishing the features of migration and accumulation of biogenic elements and ecotoxicants, is a promising area of research to develop measures to prevent pollution of soil, groundwater, open reservoirs and plant products.
