**3.1.3 Soil characteristics**

Different root characters occur according to soil structure. Root enlarges, spreads and grows with its small roots and enlarges and deepens in well aired and sandy soil. Shallow and distributed root bodies are formed in silty, clayey or drained sub soil. Roots of some plants' same species have different characteristics in different soil structure. It is difficult to transplant plants in an areas furnished with solid construction material or densely vegetated with plants (Kim, 1988).

Appropriateness of soil aspects from which the plant is removed is as important as the plant species. Some soils can be as effective as the plant species in growing a root system which is compact and rich in terms of hairy root. As plants that grow in sandy soil forms deep and complicated root systems, they are more risky in transplantation when compared to the plants removed form clayey soil. But as there is not enough oxygen in clayey soil, capillary roots that are very important in new root formation don't grow enough. Because of this, ventilation of soil with different methods increases the level of success. Deep soil without any rocks, logs etc. are better in removing big plants (Ürgenç, 1998).
