Abstract: 
In soil of the arid and semi - arid regions of Iran which is very salinity is very wide spread, salinity is the most important limiting factor. Application of biological systems is one of most suitable methods for salinity rehabilitation in these areas. A research project was conducted to solve a part of the salinity problem in Chah- afzal region consisting of five treatments based on a randomized systematic statistical design. The treatments consisted of five identical areas with different Atriplex cover and management system v: 1. control area (no Atriplex vegetation cover), 2. Atriplex vegetation cover without pruning.3. Atriplex vegetation cover with every year pruning, 4. Atriplex vegetation cover with pruning in every two year intervals, 5. Atriplex vegetation cover with every three year pruning intervals. The soil chemical parameters consisted of EC, pH, Na and SAR Were measured in three different soil depths of 0-20, 20-40 and 40-80 centimeter. The results showed that Atriplex lentifomis significantly decreased soil salinity to 40cm of soil depth. However, no significant effects was observed by pruning on measured soil parameters. Due to the ability of this spices in soil salinity decrement along with its potential characteristics for forage production, it could be recommended for rehabilitation of degraded rangeland in similar ecological regions.
