Abstract
This study aim to the effect of some trees groups on the chemical soil properties. this work on the select forest in the Dubis region which establishment in 1964. selected some species of Trees for this study (Morus alba L and Platanus orientalisL. ) as deciduous trees and Eucalyptus camaldulens as tree evergreen, Pinus brutia Ten. as evergreen needle tree and Tamarix Arabica as deciduous needle tree. Labor work were involved on the determined and measured of some soil chemical properties (pH, EC, O.M, CaCO3, CEC, Soluble Ions). results concluded that the pH in surface horizons were decreased under species of trees selected for compared , which ranged between 7.10-7.42 with control as the value of the soil 7.53 interaction and varied depending on the vegetation species. The electrical conductivity were increased under species of trees compared to the open ground location. It was noted there is a high content of organic matter as it reached the surface horizon under groups of trees 37.84, 31.68, 30.80 and 27.64 gm. kg-1 compared with 15.33 gm.kg-1 of open land and taken in the following arrangment Platanus orientalisL.> Morus alba L.> Tamarix Arabica> Eucalyptus camaldulens >Pinus brutia Ten. As well as with CEC.
