The protection and improvement of natural resources especially for desert vegetation need a comprehensive recognition of natural resources and relationship on Soil characteristics. One of the most important species growing in sabzevar desert is Stipagrostis pennata and in the current research the relationship between the physicochemical properties of the soils and growth characteristics of the S. pennanta including density, canopy cover and amount elements of soil have been studied in the land. A random systematic design has been applied in 4 sites called A, B, C, and D within a distincthabitat of S. pennanta. Soil samples have been taken from 2 depths (0 - 30 cm) and 30-60 and prop Hon of clay, silt and sand content, amount of N, P, K, C, Na, Ca and Mg have been determined in a soil lab. The soil physico–chemical and plant growth data have been analyzed through statistical methods using the SPSS software. Further finding of this study show that the growth characteristics of S. pennanta such as density, canopy cover and forage production rarely depend on soil chemical properties but there is a statistically significant positive correlation between the canopy cover and amount of Ca. This has been shown by higher canopy cover in site B which has higher Ca..The results show that there is direct relationship between the amount of nitrogen and growth properties off of Stipagrostis pennata and other elements of the soil was not significant.
