The aim of the research is to assess the properties and ecological condition of urban soils, along with their ability to foster the growth and development of plants on residential lawns within the cities of the Kama region. It has been confirmed that urban stratozems and urban quasi-soils with a sandy loam-sand granulometric composition have formed on the sandy terraces of the Kama River over several decades. The properties of urban soils have largely changed as a result of the deposition of lowland peat on the surface. The topsoil is typically distinguished by its carbonate content, an alkaline medium, a high availability of mobile phosphates, and considerable fluctuations in organic carbon content, exchangeable potassium, catalase, and cellulolytic activities. According to the results of phytotesting, the urban soils exhibited a satisfactory ecological state along with moderate levels of toxicity. The presence of alkalinity and exchangeable sodium in certain soils adversely impacted the test culture. During the research, assessing the impact of the modified lowland peat that has accumulated on the surface in the current carbon balance of the urban area proved to be a challenge.
