Abstract

Soil carbon changes is one of the most important indicators impacts of Climate change impacts on Soil genesis. Study of soil carbon, including organic and inOrganic carbon (carbonates) and its impact on other soil characteristics in different Climates, is essential for the proper management of soil carbon on a global scale. It is too important the balance between different parts of carbon sources in the environment. In current study, organic and inOrganic carbon complex with primary particles were studied in 9 profiles a climosequence including three Climates arid, semi-arid and semi-humid with typic aridic, dry xeric and typic xeric moisture regimes and mesic and thermic temperature regimes. Results showed that the amount of Organic carbon in all three components decreases with increasing depth and also clay component has more Organic carbon content in all depths compared with other components of soil. Contrast to Organic carbon, inOrganic carbon content is lower in surface horizon compared with the subsurface in all three components of particle size and increases with increasing depth. The avearage of Organic carbon components of particle size in three studied regions showed that the following trend clay (1. 1%) > silt (0. 68%) > sand (0. 23%), while inOrganic carbon in the soil with trend silt (14. 41%) > sand (12. 11%) > clay (8. 14%).
