THE ІMPACT OF WINTER PIT CLOSURE TECHNOLOGY ON THE AGROCHEMICAL STATE OF SOIL UNDER TREE PLANTINGS IN THE URBAN CONDITIONS OF VINNYTSIA

Abstract

Tree plantings play a significant role in urban development and the improvement of human settlements. They are one of the key tools for enhancing the living conditions of residents in cities, towns, and villages. These plantings contribute to improving the microclimate and increasing the aesthetic appeal of the architectural environment. Green zones serve essential functions aimed at ensuring a comfortable urban life.In modern urban planning, the interaction between the natural environment and urban infrastructure is considered a fundamental aspect of a city’s development, regardless of its size. Therefore, green plantings are viewed as integral structural elements of urban space. They play a crucial role in the organization of territories by forming compositional centers, separation zones, and framing residential areas.Undoubtedly, in order to ensure the healthy growth and development of trees, it is necessary to create favorable growth conditions, which include not only proper care but also the consideration of external factors, particularly technogenic influences. The agrochemical state of the soil is of great importance and is significantly influenced by the applied maintenance technologies, especially the method of winter pit closure.This approach helps preserve soil moisture, reduce erosion processes and the impact of low temperatures, and ensures better conditions for the root systems of trees in urban environments.This article examines the impact of winter pit closure technology on the agrochemical state of soil under tree plantings. The study was conducted to assess changes in the main agrochemical indicators of the soil as a result of applying the winter pit closure method. It was found that the winter pit closure technology helps reduce moisture loss, stabilize the temperature regime of the root system, and maintain soil fertility.The research results showed that the use of closed pits during the winter period significantly reduces soil salinity levels. The most notable reductions were observed in the most saline locations: on Soborna Street and Pirogova Street, salinity levels decreased by 75,3 and 73%, respectively.On Zamostianska Street, where salinity levels were within normal limits, winter pit closure allowed for a 37% reduction in soil salt content. On Poryka Street, where salinity was low, the salt content in the soil decreased by 28,7% due to the closure of pits for the winter period.
