Soil researches of recreational areas and street protective green plantations were carried out in Alytus city in 2009-2019, in accordance with the "Greenery and Green plantations Condition Monitoring Program, 2008". The soils in the park areas are noncarbonated, with a predominantly sandy fraction and poorly structured. Soil near streets have been found to be alkaline (pH 6.7-7.9), less alkaline (pH 8.2-8.4); in the area of newly planted streets and recreational greenery - alkaline (7.1-7.9). The amounts of P, Na, Ca, Mg, Cl correspond to the background indicators of Lithuanian soils. According to the amount of mobile potassium (K2O), soil is low in potassium and mobile phosphorus (P2O5) varies from low amount (51-100 mg kg-1) to high amount (> 200 mg kg-1) groups. The main amount of heavy metals were present under the limits of background concentration (or less). [ABSTRACT FROM AUTHOR]
