Abstract

Based on experimental observations monitored parameters are to solve the mutual relationships within the atmosphere – soil – plant system during the years 2019–2023. The current structure of the interest area ​represents a strongly anthropogenically modified urban landscape with a high built-up area directly in the site and in the vicinity of the monitored site itself. The focus is on soil cover, considering the quality of urban soil and climatic parameters assessed from the perspective of ongoing climate change. Urban soils develop their specific soil properties under the strong influence of the environmental environment and often depend on their use in the urbanized area, which is diverse. From the analysis of the chemical analysis, the contents of individual parameters in the soils are largely influenced by the exogenous effects of the urban environment. Increased mineralization of organic matter is recorded and reduced supply of soil nutrients (especially phosphorus) due to the absence of macro-nutrient application. The content of carbonates in the range from 14% to 23% is considerably high, which is a consequence of the high proportion of construction and industrial waste (anthroskeleton). It has been shown that the amount of humus in urban soils is a significant factor influencing and largely determining the success of plantings and the ability of tree species to survive in urban environments. The park planting of black walnut is in very good condition, given to the soil and climatic conditions and due to permanent maintenance. During the years under review, black walnut showed good drought and high calcium content tolerance, which is primarily due to good rooting. The results of soil analyses confirm that black walnut can adapt to deteriorating climatic conditions, provided that the soil conditions are of sufficient quality.
