Abstract: 

Some dry lands afforestation projects are accomplished in Rocky slopes. Rock crevices of rocky slopes provide suitable microsites for small tree. In this study we measured amount of EC, pH, organic materials, CaSO4, CaCO3, soil texture, N, P, K, soil moisture and gravel in soil on rock crevice of limestone lithology that three small tree establishment in these. The results show significant differences between soil moisture of 10-30 and 30-50 cm depth between crevices that different small tree establish, but our result doesn’t show significant differences on other soil characteristics between different small tree establishment sites, also these results show that there is only difference significant on soil moisture between live and dieback small trees establishment site. It was concluded that the amount of soil moisture could be played key important role in small tree survival and establishment on limestone rocky slope in arid lands.
