The Carbon Sequestration in Three Soils Types with Different Plant Coverage in Gazvin and Zanjan Provinces

The aims of the current research were determination of the carbon sequestration in three soils types with different plant coverage in Gazvin and Zanjan provinces. One of the studied sites was located in Gazvin province with slaine soils. This site was covered with plants for slaine soils. The second site was located in Zanjan province with gypsic soils. This site was covered with plants for gypsic soils. The third site also was located in calcie soils of Zanjan province. This site was under barley cultivation. The sequestrated carbon was studied in 2 layers of each soil profile including 0-30 and 0-100 cm and the distribution ofthe organic carbon were mapped by GIS software. The results showed that the total soil organic carbon was significantly different among the locations. Total carbon stores of 0-30 cm for the first, second and third locations were 279, 303 and 220 ton/ha, and carbon stores of 0-100 cm for the first, second and third locations were 486, 320 and 602 ton/ha, respectively.
