Impacts of grazing management on some soil characteristics physical and chemical in semi-steppe rangelands

This research was performed in semi-steppe rangelands of Fars province in the Cheshmeh Anjir region, in 2013. Soil sampling was performed in a random-systematic manner. In each area, three transects of 50 m were established randomly with a proper distance in an area of about two hectares, and on each transect, two soil profiles were dug. The soil samples were collected from two depths of 0-25 and 25-60 cm. The experiment was laid out in a split-plot in a randomized complete block design with three replications. The study area at three levels (key, reference and critical) and the sampling depth at two levels (0-25 and 25-60 cm) were considered as main factor and sub-factor, respectively. The statistical analysis was performed using SPSS software. Mean comparison was performed by Duncan's test. The results of this study showed a significant difference (p
