Comparison of soil properties under native Salsola yazdiana Assadi floor with exotic plants Atriplex lentiformis Breweri in semi-desert rangelands (case study: Tabas rangelands)

Perennial shrubs cause to change the soil quality of their habitat through litter fall and root penetration. This research was aimed to investigate the effects of two range species on the soil surface. The study was conducted in a part of steppe rangelands in Tabas County. Soil sampling was performed completely random at 0-20 cm soil depth with two treatments including beneath the stratum and control group. Soil chemical properties including EC, organic matter and soluble sodium and chlorine were measured. Data analysis showed that the soil chemical properties measured beneath the stratum of both species differed significantly as compared with the control group (P
