Compare Desert Environments Soil Physical and Chemical Characteristics with Different Vegetation(Case Study: Southwestern of Sistan Region)

The objective of the study was to compare the desert environments soil physical and chemical characteristics with different vegetation types. This study has done in southwestern of Sistan region (Tasoki and Torsh Ab).
Study

The study areas were distinguished based on geologic maps in scales of 1:50,000 and field observations, and global positioning system (GPS). Four soil samples were taken from the 0-45 cm depth at each location and analyzed for pH, EC, organic matter, organic carbon, nitrogen, CaCO3, ESP, potassium, moisture, sodium, phosphorus, magnesium, calcium, sodium adsorption ratio, chlorine and texture. Dates were analyzed using SPSS software. 

The data indicated that there are no statistically significant differences between soil properties including: pH, nitrogen, phosphorus, moisture, magnesium, and silt, at the 0.05 levels (p> 0.05). But, there are statistically significant differences between soil properties including: organic matter, organic carbon, CaCO3, ESP, potassium, sodium adsorption ratio, calcium, clay and sand were statistically significant at the 0.05 levels (p< 0.01).

Concluded that the study area soil no limits to incrase of vegetation cover. The studies concluded that there were no soil limite for incrase of vegetation cover in study area.
