Abstract
Problem Statement and Purpose. Soils occupy a special place in the biosphere, ensuring its biological productivity. At the same time, they experience the greatest anthropogenic impact, as one of the important chains of the circulation of pollutants. Within the village settlements, the main pollutants of the soil are chemical protection products of plants and fertilizers used in agriculture, emissions of motor vehicles and individual enterprises, landfills. These contaminations can negatively affect the quality of agricultural produce grown on agricultural lands and farmland plots of the rural population. The purpose of the work is to find out the impact of the economic activity of the village of Rozivka on the ecological status of soils. Data & Methods. These materials are derived from our own field and analytical studies. The selection of soil samples was conducted taking into account the location of the main pollutants in the village (roadside lawns, industrial sites, landfills and agricultural land) and within the natural, conventionally clean zones (private plots, park area). Analytical studies of physical and chemical properties of soils were carried out according to generally accepted standardized methods. Estimation of the ecological condition of the soil cover of the village Rozivka was determined by the method of biotesting with the help of plant test systems by the method of A.I. Gorova. Green Peas Maxigolt was used as a test culture. Results. Studies conducted show that the economic activity of the population of the village Rozivka greatly affects the change of physical and chemical properties of soils, worsening their ecological status. One of the universal methods that makes it possible to obtain a comprehensive toxicological characteristic of integrated soil contamination is biotesting, which allowed to establish that, despite the high content of humus and nutrients in selected soil samples of the territory of the village within the limits of the influence of road transport, industrial enterprises and landfills, seed germination rates, the length of the ground and underground part of the germs is lower compared to the soil samples, selected on conditionally clean territories and control place (croft). The worst morphometric indicators of germination of peas are characterized by soil samples taken in the zone of dual impact of vehicles and industrial enterprises “Odessavinprom” – 47%, which indicates their high pollution. The phytotoxic effect is highest for soils selected near unauthorized landfills and corresponds to a high level of contamination. Consequently, the main factors influencing the decrease of seed germination and inhibition of the growth of Green Peas Maxigolt germs in the conditions of rural economy are the accumulation of toxicants in the soil, which are caused by emissions of road transport and industrial enterprises, the introduction of low-quality mineral fertilizers and meliorants, high alkalinity of soils. Particularly environmentally dangerous are soils near landfills.
