This study was carried out by investigating the effect of exclosure on some soil properties and carbon sequestration in Dozalum dry rangelands of Golestan province. In this study, soil sampling was performed using systematic-random method and the establishment of three transects with a length of 100 meters, points were identified along each transect. Soil samples were taken at each point. Soil samples were taken at each point. A total of 30 samples of topsoil (from a depth of 0-15 cm) were taken in each area. Then in the laboratory, soil properties, bulk density, soil porosity, soil moisture, acidity, electrical conductivity, sodium, potassium, calcium, magnesium, lime, nitrogen, sodium uptake ratio, and soil carbon were measured. An independent t-test was used to compare the control and exclusion zones for homogeneous data and Mann-Whitney nonparametric test was used for the carbon variable. The data obtained from the experimental results were analyzed using SPSS software. To evaluate the performance of carbon sequestration, carbon tax policy and carbon emission costs were used as the shadow value of carbon. The results of the analysis of changes in soil parameters at the two sites show that rangeland confinement for 15 years in the study areas had little effect on soil properties and only the ratio of sodium uptake was statistically significant. The results also showed that the rangeland confinement operation in comparison with the control area had no significant effect on the amount of deposited carbon and the confined area has an economic value of 255909.5 Tomans in terms of carbon sequestration function. %> http://drnl.sanru.ac.ir/article-1-149-en.pdf %P 1-11 %& 1 %! %9 Research %L A-10-384-3 %+ Desert Management, Gorgan University of Agricultural Sciences and Natural Resources %G eng %@ 2717-4425 %[ 2021
