Plane is one of the most important trees used in urban landscapes. In most urban lands all over the world, chlorosis is the main problem. Urban landscape trees are planted in a compacted soil around new construction. Compacted soil restricts rooting area and decreases root penetration. Compaction also appears to decrease tree establishment and dramatically reduce shoot growth. Inoculation of plants’ root with mycorrhizal fungi can be used as a method to increase plants’ nutrition. The objective of this study was to examine the effect of inoculation with mycorrhizal fungi on nutrients’ uptake and reducing of cholorosis in mature plane trees by soil compaction remediation. An split split plot experiment was carried out based on a completely randomized design with three replications in two successive years and under two irrigation system. Treatments were included an N-P-K fertilizer with manure, a mixture of mycorrhizal fungi ( Glomus Intraradices and G. mosseae ) with manure, a mixture of mycorrhizal fungi with N-P-K fertilizer and manure, and control (only manure). The results showed that, inocultion of plants with mycorrhizal fungi increased fresh and dry weights of leaves, soluble sugar content, P and Fe content, total protein and the activity of superoxide dismutase and peroxidase enzymes. The results also showed that the drip irrigation increased fresh and dry weights of leaves, soluble sugar content, greenness and health of trees, chlorophyll and carotenoid content, N content, and the activity of superoxide dismutase and peroxidase enzymes. The majority of measured parameters in the second year were significantly increased. Finally, the results of this experiment showed that drill hole nutrition by applying mycorrhizal fungi, resulted in soil compaction remediation and improve the health and greenness of plane trees by increasing nutriens uptake.
