To find the effect of Atriplex canescens on soil chemical properties, two adjacent areas, each with and area of 1 ha, were selected in Hossein Abad Hapeshloo Shahryar. In one area it was planted Atriplex canescens in 2003 while the later one without Atriplex canescens was considered as control area. To sample soil, random- systematic method was used along 3 transects with a length of 100 m. In planting site transects were established perpendicularly on furrows were while in control site they were established parallel. Along each transect, 3 profiles were dug in initiate, medium and end points of each transect under shrubs and samples were taken from two depths (0- 30 cm and > 30 cm). Then, soil characteristics including texture, pH, Ec, Lime (CaCo3), ESP, organic mater (OM) and elements of Na, K, Ca, Mg and N were measured in laboratory. The results of this study showed that pH and Mg were significantly reduced in planting site compared of control. In addition, Na, Mg, Lime and Ca were significantly increased in planting site in comparison to control.
