Abstract
Due to the effect of atmospheric carbon absorption and sequestration, this study is investigated the effects of exclosure and grazing on carbon stoage by Astragalus gossypinus in the part of the cold semi-arid rangelands of Vezvar in Behshahr. After determination of key area, two sites consist of exclosure and grazed area was selected and plant and soil sampling was done by random-systematic method. Thus, 20 plants and 40 soil samples were collected totally. Conversion coefficient of enclosure rangeland (٪0.78) was more than the grazed rangeland. Carbon stoage rates of roots with 19/9 kg/ha in exclosure area and grazed area with 8/33 kg/ha was more than the stem and leaf. Overall, the rate of carbon stoage in enclosure area with 1036467.022 kg/ha was more than grazed area with 976082.806 kg/ha and had not significant different. Investigation of carbon storage in soil showed that soil was stored more carbon to the plant biomass.
