ABSTRACT Root environment and soil composition play an important role on growth and development of the roots and, consequently, the trees. In this research, the effect of some physical and chemical properties of two soil types, including a typical agricultural soil and an urban soil with three soil depths (0-40cm, 0-80cm and 80-120cm), on the growth of plane trees in an urban environment were examined. Plan trees were selected as the typical tree types planted in Mashhad urban landscape. The agricultural soil type was upplied from local agricultural fields and the urban soils type was sourced from urban street landscapes in Mashhad. The results showed that there were significant differences in all measured traits including soil density, lime percentage, soil pH and EC, organic carbon percentage, nitrogen, phosphorus and potassium content. The results of leaf analysis showed that the trees cultivated in the urban soil had lower nitrogen and phosphorus absorption compared with trees planted in agricultural soil. In urban soils, soil density increased, which can be due to urban planning standards. In addition to soil compaction, nutrient shortages, inappropriate pH and high EC and other adverse soil conditions, tree growth will reduce and shortage of tree nutrients will occur. Due to the importance of trees in the city's life, a suitable planting bed for receiving water and nutrient for trees in urban soils should be provided.
