Abstract: 

This research was done to investigate the influence of exclosure (for 5 years) and grazing (continuous grazing) on the organic carbon content and soil bulk density in the central Albors south slopes rangelands in the spring of 1383. Using VAL. BL. And CRUM methods, organic carbon and soil bulk density was calculated. The soil organic carbon in grazing conditions in the depth of zero to 20 centimeters was higher (55.9 ton per hectare) showing significant differences in 5% level while in the depth of 20 to 50 centimeters (67.3 ton per hectare for grazing and 63.8 ton per hectare for exclosure) no significant differences was seen in 5% level. The soil carbon content up to the depth of 50 centimeters was 123.2 ton per hectare in grazing conditions and 108.2 ton per hectare in exclosure conditions. In exclosure conditions the amount is less, that showed significant differences between grazing and exclosure conditions in 5% level.
