Survey of relation between soil organic carbon in different vegetation systems (orchard, arable and forest) with chemical, physical and classification soil characteristics (case study: parts of land Ramsar)

The increasing concentration CO٢ in atmosphere the main agent of Climatechange, change ecosystems. Forthermore bearing looks necessary, Preventemissions excessive levels of pollution tolerance threshold of carbon dioxideatmosphere. while the have different vegetation ecosystems InfluenceImpressive on the carbon sequestration. This research was done to targetassessment the soil carbon sequestration, in tree type vegetation systems,citrus orchard, arable and forest in city of Ramsar. sampling points werechosen on map, sampling of depth ٠ to ١٠٠ cm, with harvesting ١٥ samplesoil in the user in total, ٤٥ sample was harvesting .in addition some of themost important soil properties, soil texture, acidity, soil bulk density, organiccarbon, total nitrogen and CaCo٣were measured in the laboratory. Resultsshowed that , sequestrated carbon in the forest(٤٥٣٢.٣٥ ton/ha)was most oforchard (٢٩٩٧.٦٦ ton/ha) and arable (paddy soil) (٢٦٨٢.٥٥ ton/ha). Also themost nitrogen, organic carbon ,organic matter and sequestrated carbon in thedepth of ٠ to ١٠ cm was ٨٦٦.٩٦٨ ton/ha in forest and least ٣٩٣.٤ ton/ha inarable (paddy soil). Map sequestration carbon in the profiles study drawnsystem GIS. in the study area four class soil included Alfisols, Inceptisols,Mollisols, Entisols.Totally it could be said that the process of carbon sequestration is importantfor water and soil quality, fertility increment and preventing the erosion.Therefore the forest ecosystem should be managed in order to increase thecarbon sequestration potential.
