The purpose of the research is to compare the effect of Tamarix aphylla (L.) and Atriplex canescens (Pursh) Nutt. cultivation on the soil's properties. The species were cultivated in a land with the area 42 ha and with the spacing 5m*5m in 1993 in Zahak, northern Sistan and Balochistan pro. Soil samples were taken at the depth of 0-30 cm and 31-60 cm with 8 replicates from any habitat and the control area using auger based on random-systematic method. physicochemical properties were measured, including soil texture, phosphorous, potassium, nitrogen, organic matter, T.N.V, EC and pH. Data analysis was performed using one-way ANOVA and Duncan's test. The results showed that there were differences between the properties of the region's soil. In other words, the soil EC of A. canescens (47.98 mmhos/cm) was more than that of T. aphylla (15.70 mmhos/cm) and the control area (15.80 mmhos/cm) at the depth of 0-30 cm. The soil pH of A. canescens (8.92) was also more than that of T. aphylla (8.62) and the control area (8.70). The available potassium in T. aphylla habitat (460 ppm) was also more than that in A. canescens habitat (325 ppm) and the control area (180 ppm). At the depth of 31-60 cm, the soil pH of A. canescens (9.02) was more than that of the control area (8.65). Therefore, it is more suitable to cultivate T. aphylla as a native species than A. canescens for biological restoration of the region.
