Parent material and vegetation are two important and influential factor in the formation of soil. Type of elements in the soil and their availability to plants depends heavily on soil parent material, as different parent material releases different amount of element during the weathering process. However, type and density of vegetation change with amount of organic matter and mechanism of element cycle, Overshadowed the availability of element in rangeland ecosystem. Botanical characteristics of the vegetation and the amount of plant residue added to the soil, determined importance of that plant species in releases of the element in soil and uptake by plant. Heavy elements that existing in pasture soil, with Entering to the plant and animal tissue come into the human food chain and endanger human health. Therefore studies the Trend of change of heavy element in soil and amount of heavy element Absorbed by plant can provided necessary knowledge to predict human health risks. This study were conducted to investigated profile distribution of heavy element and nutritional affected by Astragalus and Daphne and different parent material in upland rangeland around Koohrang city as an example of the Zagros rangeland. The experiment were conducted as factorial and completely randomized design with three replicated. In The study area selected three different parent material that included fossiliferous argillaceous limestone, fossiliferous dolomitic limestone and fossiliferous conglomerate red sandstone and in each parent material three places were selected. In each place two profiles with Astragalus and Daphne and a profile for the region without the plant as a control profile to depth of 100 cm were drilling and sampled. Then the physical and chemical properties and concentrations of nutritional and heavy element in soil profile (including soil texture, pH, the amount of lime and etc) and the concentration of heavy element (zinc, copper, iron and nickel) was measured in plants. The results showed that heavy metals have significant positive correlation with organic carbon and cation exchange capacity and a significant negative correlation with amount of soil lime. Existence of vegetation with effects on soil organic carbon, have an important role in fixing the heavy element in top soil and increase the availability of nutrients in the upper horizon. Organic matter as an important elements absorbent and kept them at surface of soil and prevent movement of them in profile depth. Type of parent material have significant effect on amount of soil element while the vegetation in some cases could not make a significant difference in concentration of element. Red conglomerate parent material Because of more resistance to weathering have a coarser texture and release fewer element compare to argillaceous limestone and dolomite in soil. Soils formed on limestone marl and limestone dolomitic parent material because of more development and due to more soil depth have more organic matter, cation exchange capacity and percentage of clay and silt compare with soils formed on red conglomerate. Soils formed on the red conglomerate parent material due to coarse texture compared to limestone parent material have more sand. Trend changing of total and adsorbed concentration of element in profile is similar, so that changes in different depths of the profiles obeyed a similar pattern.
